To supply.

  In addition, the video / audio processing unit 193 causes the display unit 236 to display a video corresponding to the video signal supplied to the display unit 236. Further, the video / audio processing unit 193 causes the audio output unit 237 to output audio corresponding to the audio signal supplied to the audio output unit 237.

  The operation unit 126 is an operation key, a power button, or the like provided on the HDD recorder 32. When the user operates the operation unit 126, an operation signal corresponding to the operation by the user is supplied to the system controller 121. The operation unit 126 does not need to be provided in the HDD recorder 32. For example, the operation unit 126 may be provided in a remote controller (not shown) that operates the HDD recorder 32. In this case, the user operates the operation unit 126. Then, an operation signal corresponding to the operation by the user is supplied to the system controller 121 by wireless such as infrared rays.

  The audio output unit 237 outputs audio corresponding to the audio signal supplied from the video / audio processing unit 193 of the HDD recorder 32.

  Next, a command transmission process in which the mobile phone 31 transmits a command instructing recording of a program together with the recording target determination information will be described with reference to the flowchart of FIG.

  This command transmission process is started when the user operates the operation unit 68 of the mobile phone 31 so as to start viewing a predetermined program. At this time, the system controller 61 is supplied with an operation signal from the operation unit 68 according to a user operation.

  In step S31, the system controller 61 initializes the variable n to the value 0.

  Thereafter, the system controller 61 determines, based on the operation signal from the operation unit 68, one-segment specific information that identifies a predetermined program that the user has started to view, and is the same as the predetermined program that the user has started to view. It is converted into TV-specific information that specifies the content program.

  Here, the specific information for one segment is information for specifying a predetermined program broadcasted by one-segment broadcasting, and the specific information for TV is information for specifying a predetermined program broadcasted by TV broadcasting. . The system controller 61 uses a specific information table in which specific information for one seg and TV specific information for specifying a program having the same content as the program specified by the specific information for one seg are associated with each other. The specific information for one segment can be converted into the specific information for TV.

  The reason why the 1Seg specific information is converted into the corresponding TV specific information is that a program having the same contents generally uses different channels for the 1Seg broadcast and the TV broadcast.

  The process proceeds from step S31 to step S32, and the system controller 61 generates a command for instructing recording of the program, and the communication unit 71 together with the TV specific information obtained by converting the specific information for 1seg. To the HDD recorder 32.

  That is, in step S <b> 32, the communication unit 71 transmits a command for instructing recording of a program to the HDD recorder 32 together with the TV specific information supplied from the system controller 61 as recording target determination information.

  After the process of step S32 is completed, the process proceeds to step S33, and the communication unit 71 transmits the TV specific information and command within a predetermined time according to the control of the system controller 61. Whether or not a response indicating that the information and the command have been normally received is received from the HDD recorder 32, that is, whether or not the HDD recorder 32 has normally received the TV specific information and the command from the communication unit 71. Determine.

  When it is determined in step S33 that a response indicating that the TV specific information and command are normally received from the HDD recorder 32 is received within a predetermined time after the TV specific information and command is transmitted. The processing proceeds to step S34, and the video / audio processing unit 65 displays on the display unit 66 a display indicating that the TV specific information and command have been normally received by the HDD recorder 32, under the control of the system controller 61. The process is terminated.

  On the other hand, in step S33, if a response indicating that the TV specific information and command are normally received is not received from the HDD recorder 32 within a predetermined time after the TV specific information and command are transmitted. When it is determined, the process proceeds to step S35, and the system controller 61 adds the value 1 to the variable n and sets the resultant added value as the value of the new variable n. Then, the process proceeds to step S36. Proceed to

  In step S36, the system controller 61 determines whether the variable n is larger than the threshold value Th_n. Here, the threshold value Th_n represents the number of times that the TV specific information and command are transmitted until the HDD recorder 32 normally receives the TV information. For example, the threshold value Th_n is a value set in advance when the mobile phone 31 is manufactured at the factory. .

  If it is determined in step S36 that the variable n is not greater than the threshold value Th_n, the process returns to step S32, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S36 that the variable n is larger than the threshold value Th_n, the process proceeds to step S37, and the video / audio processing unit 65 performs the TV recording by the HDD recorder 32 according to the control of the system controller 61. The display unit 66 displays a display indicating that the specific information and command for use have not been received normally, and the process ends.

  Next, a recording process in which the HDD recorder 32 records a program specified based on the recording target determination information from the mobile phone 31 will be described with reference to the flowchart of FIG.

In step S <b> 71, the antenna 122 receives a broadcast wave of TV broadcasting and supplies a corresponding RF signal to the tuners 161 _{1 to} 161 _N of the recording processing unit 123.

In step S71, each of the tuners 161 _{1 to N} demodulates RF signals of different channels from the RF signal from the antenna 122, and records the resulting programs as recording buffer buffers 162 _{1 to} 162 _N, respectively. To be recorded temporarily.

As a result, all programs of different channels broadcast by TV broadcasting are temporarily recorded in the recording ring buffers 162 _{1 to} 162 _N for the latest predetermined time.

  Thereafter, when the communication unit 71 of the mobile phone 31 transmits the TV specific information and command to the HDD recorder 32 in the process of step S32 of FIG. 6, the process proceeds from step S71 to step S72, and the communication unit 128 Under the control of the system controller 121, the TV specific information and command from the communication unit 71 of the mobile phone 31 are received and supplied to the system controller 121, and the process proceeds to step S73.

  In step S73, the system controller 121 determines whether or not the TV specific information and command supplied from the communication unit 128 is error-free information (data), that is, the communication unit 128 receives the TV from the mobile phone 31. It is determined whether or not the specific information and command can be normally received.

  If it is determined in step S73 that the TV specific information and command could not be received normally, the communication unit 71 of the mobile phone 31 again performs the TV specific information in the process of step S32 of FIG. After waiting for the information and command to be transmitted to the HDD recorder 32, the process returns to step S72, and thereafter the same process is repeated. In the process of step S32 of FIG. 6, when the communication unit 71 of the mobile phone 31 no longer transmits TV specific information and commands to the HDD recorder 32, that is, in step S36 of FIG. When it is determined that the threshold value Th_n is greater than the threshold value Th_n, the process of step S73 is terminated, and then the process is terminated.

  On the other hand, if it is determined in step S73 that the TV specific information and command have been successfully received, the process proceeds to step S74, and the system controller 121 normally receives the TV specific information and command. A response indicating that it has been received is generated and supplied to the communication unit 128, and the communication unit 128 is controlled to transmit the generated response to the mobile phone 31.

  After the process of step S74 ends, the process proceeds to step S75, and the system controller 121 specifies a recorded program that is a program to be recorded (recorded) based on the TV specific information from the communication unit 128.

  Further, the system controller 121 controls the recording processing unit 123 in accordance with a command from the communication unit 128, and causes the recording processing unit 123 to record the specified recorded program in steps S76 and S77.

That is, the process proceeds from step S75 to step S76, and the video processing unit 163 _n (n = 1, 2,... N) of the recording processing unit 123 temporarily records from the recording ring buffer 162 _n in step S71. The recorded program is appropriately read out, and processing necessary for recording the recorded program in the moving image content recording unit 124 is performed. Further, in step S76, video and audio processing unit 163 _n has a recorded program after processing, and supplied to the write unit 164 _n, the writing unit 164 _n has a recorded program after processing supplied thereto, the video content recorded To the unit 124 for recording.

  Thereafter, the process proceeds to step S77, and the system controller 121 determines whether or not the end time of the recorded program has been reached. If it is determined that the end time of the recorded program has not yet been reached, the process proceeds to step S77. Returning to S76, the same processing is repeated thereafter.

  On the other hand, if it is determined in step S77 that the end time of the recorded program has been reached, the process ends.

  As described above, in the command transmission process of FIG. 6 and the recording process of FIG. 7, when the user operates the mobile phone 31 so as to view a predetermined program, the mobile phone 31 has the TV specific information, Since the HDD recorder 32 automatically records a predetermined program specified by the TV specific information from the mobile phone 31 in accordance with the command from the mobile phone 31, the command is transmitted. Can watch an unviewed portion of the predetermined program using the HDD recorder 32 even if the viewing of the predetermined program performed using the mobile phone 31 is interrupted.

Further, before receiving the TV specific information and command from the mobile phone 31, the HDD recorder 32 temporarily records the latest predetermined time of the recorded program in the recording ring buffer 162 _n in step S71. Therefore, recording can be started from a time before the time when the TV specific information and command are received from the mobile phone 31. For this reason, the user uses the HDD recorder 32. It is possible to view a scene (for the latest predetermined time of the recorded program) before the start of viewing by the mobile phone 31.

  Further, every time the user operates the mobile phone 31 so as to change the channel, the program corresponding to the changed channel is automatically recorded in the HDD recorder 32. For example, the user can now watch Even if the cellular phone 31 is operated so that the channel of the program A being operated is changed to the channel of another program B, the program A is recorded on the HDD recorder 32. As a result, by viewing the program B using the mobile phone 31, the program A that could not be viewed can be viewed later using the HDD recorder 32.

  Here, when the user operates the mobile phone 31 to view a predetermined program, the predetermined program that the user views is automatically recorded on the HDD recorder 32. However, when viewing an unviewed scene, which is not viewed by the user, of the scenes constituting the predetermined program started to be viewed using the mobile phone 31, using the HDD recorder 32, the user is not viewing Until the scene is reproduced, it is necessary to perform operations such as fast-forwarding the scene of a predetermined program recorded in the HDD recorder 32.

  Next, a method by which the user can seamlessly view an unviewed scene that the user has not viewed without performing an operation such as fast-forwarding a predetermined program recorded in the HDD recorder 32 will be described.

  FIG. 8 is a diagram schematically illustrating processing performed by the information processing system of FIG. 1 that realizes such a method.

As shown on the upper left side of the figure, the user operates a mobile phone 31 capable of watching 1Seg so as to view a certain program, and views a certain program from scene 1 to scene 5. At this time, when the user starts viewing a certain program, the viewing that represents the relative time in the time required to reproduce all the programs when the scene 1 output from the mobile phone 31 is started. the relative in time required and viewing start information s _n used to calculate the start time, when the scene 5 are output when viewing end of a program is terminated, to play all certain program the viewing end information e _n respectively used to calculate the viewing end time representing a such time, the history information associated with identification information of the outputted certain program, and records the viewing information recording unit 70.

  After returning home, the user operates the operation unit 68 of the mobile phone 31 so that the history information recorded in the mobile phone 31 is transmitted from the mobile phone 31 to the HDD recorder 32.

  At this time, the HDD recorder 32 receives history information from the mobile phone 31. Then, the HDD recorder 32 detects an unviewed scene that the user has not viewed with the mobile phone 31 based on the received history information, and starts reproduction from the scene 6 that is the detected unviewed scene, for example.

  Next, viewing history processing in which a user views a predetermined program using the mobile phone 31 and records history information of the predetermined program will be described with reference to the flowchart of FIG.

  This viewing history process is started, for example, when the user operates the operation unit 68 to view a predetermined program using the mobile phone 31. At this time, the system controller 61 is supplied with an operation signal from the operation unit 68 according to the user's operation. The system controller 61 receives the tuner 63 and the video / audio processing unit based on the operation signal from the operation unit 68. 65 is controlled.

  In step S131, the antenna 62 receives the broadcast wave of the one-segment broadcast and supplies the corresponding RF signal to the tuner 63. The process proceeds to step S132, and the tuner 63 performs the one-segment broadcast supplied from the antenna 62. An RF signal of a predetermined channel is demodulated from the RF signal, and an audio signal and a video signal obtained as a result are supplied to the ring buffer 64 and temporarily recorded.

After step S132, the process proceeds to step S133, the system controller 61, as the viewing start information s _n, the viewing start time s _n is a time at which the user starts viewing counts time Figure Time is measured by a timer not shown.

  In step S133, the system controller 61 determines the specific information for the one seg of the program that the user has started to watch based on the operation signal from the operation unit 68, and determines using the above-described specific information table. The specific information for one segment is converted into the corresponding specific information for TV.

Further, in step S133, the system controller 61 includes a viewing start time s _n obtained by counting, information associating the identification information for the TV obtained by converting, as history information, the viewing information recording unit 69 The process proceeds to step S134.

  In step S134, the video / audio processing unit 65 reads the video signal and audio signal that are temporarily recorded in the ring buffer 64 as appropriate under the control of the system controller 61, and the process proceeds to step S135, where the read video signal and audio signal are read. These are respectively supplied to the display unit 66 and the audio output unit 67, the image corresponding to the video signal is displayed on the display unit 66, and the audio corresponding to the audio signal is output to the audio output unit 67.

  Thereafter, the process proceeds to step S136, and the system controller 61 determines whether or not an operation signal for instructing the end of the output of the program started by the user is supplied from the operation unit 68. It is determined whether or not the operation unit 68 has been operated so as to end the viewing of the started program.

  If it is determined in step S136 that viewing of the program that the user has started viewing has not ended, the processing returns to step S134, and the same processing is repeated thereafter.

On the other hand, in step S136, if it is determined that the user is viewing the program that initiated the viewing is terminated, the process proceeds to step S137, the system controller 61, the viewing end time e _n as viewing end information e _n Keep time.

  In step S137, the system controller 61 determines the specific information for the one seg of the program that the user has started to watch based on the operation signal from the operation unit 68, and makes the determination using the above-described specific information table. The specific information for one segment is converted into the corresponding specific information for TV.

Further, in step S137, the system controller 61 includes a viewing end time e _n obtained by counting, information associating the identification information for the TV obtained by converting, as history information, the viewing information recording unit 70 Supply and record, and the process ends.

  Next, history information transmission processing in which the mobile phone 31 of FIG. 1 transmits history information will be described with reference to the flowchart of FIG.

Further, the system controller 61 reads the history information recorded in the viewing information recording unit 70 from the viewing information recording unit 70 and supplies the history information to the communication unit 71.

  Thereafter, the process proceeds from step S171 to step S172, and the communication unit 71 transmits the history information supplied from the system controller 61 to the HDD recorder 32 via wireless such as infrared rays or the network 34. The process proceeds to step S173.

  In step S173, according to the control of the system controller 61, the communication unit 71 determines whether or not a response indicating that the history information has been normally received is received from the HDD recorder 32 within a predetermined time after transmitting the history information. That is, the HDD recorder 32 determines whether or not the history information from the communication unit 71 has been normally received.

  If it is determined in step S173 that a response indicating that the history information has been normally received is received from the HDD recorder 32 within a predetermined time after the history information is transmitted, the process proceeds to step S177, and the video Under the control of the system controller 61, the audio processing unit 65 causes the display unit 66 to display a display indicating that the history information has been normally received by the HDD recorder 32, and the process ends.

  On the other hand, if it is determined in step S173 that a response indicating that the history information has been normally received has not been received from the HDD recorder 32 within a predetermined time after the history information is transmitted, the process proceeds to step S174. The system controller 61 adds the value 1 to the variable k, sets the resulting addition value as the value of the new variable k, and the process proceeds to step S175.

  In step S175, the system controller 61 determines whether the variable k is larger than the threshold value Th_k. Here, the threshold value Th_k represents the number of times history information is transmitted until the HDD recorder 32 normally receives it, and is, for example, a value set in advance when the mobile phone 31 is manufactured at the factory.

  If it is determined in step S175 that the variable k is not greater than the threshold value Th_k, the process returns to step S172, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S175 that the variable k is larger than the threshold value Th_k, the process proceeds to step S176, and the audio / video processing unit 65 performs the history by the HDD recorder 32 according to the control of the system controller 61. A display to the effect that the information has not been normally received is displayed on the display unit 66, and the process is terminated.

  Next, referring to the flowchart of FIG. 11, when the mobile phone 31 performs the history information transmission processing of FIG. 10, the HDD recorder 32 performs history information reception processing for receiving history information from the mobile phone 31. explain.

  This history information reception process is started when the mobile phone 31 (communication unit 71) transmits history information in the process of step S172 of FIG.

  If it is determined in step S232 that the history information from the mobile phone 31 has not been normally received, in step S172 in FIG. 10, the history information is again transmitted from the mobile phone 31. The processing returns to step S231, and the same processing is repeated thereafter. In step S172 in FIG. 10, when the mobile phone 31 no longer transmits history information to the HDD recorder 32, that is, in step S175 in FIG. 10, it is determined that the variable k is greater than the threshold value Th_k. The process of step S232 is terminated, and then the process is terminated.

  On the other hand, when it is determined in step S232 that the history information from the mobile phone 31 has been successfully received, the process proceeds to step S233, and the system controller 121 receives the history information supplied from the communication unit 128. And supplied to the viewing information recording unit 127 for recording.

  After the process of step S233 ends, the process proceeds to step S234, and the system controller 121 generates a response indicating that the history information has been normally received, supplies the response to the communication unit 128, and transmits the response to the mobile phone 31. . That is, in step S <b> 234, the communication unit 128 transmits a response indicating that the history information can be normally received to the mobile phone 31 according to the control of the system controller 121.

  Thereafter, the process is terminated.

  The HDD recorder 32 can detect an unviewed scene based on the history information received by the history information reception process of FIG.

  FIG. 12 is a diagram for explaining a method in which the HDD recorder 32 detects an unviewed scene that the user has not been able to view on the mobile phone 31 while away from home.

  In the figure, in the horizontal (horizontal) direction, scenes n−4 to m + 4 representing a part of a predetermined program that the user has started to watch using the mobile phone 31 are shown.

  Scenes n-4 to n and scenes m to m + 4 represent viewing scenes viewed by the user, and scenes n + 1 to m-1 represent unviewed scenes not viewed by the user.

HDD recorder 32, based on the history information from the portable telephone 31, as the relative time in the time required to play all predetermined program, the viewing end time Te _n is a time when the viewing end, and A viewing start time Ts _{n + 1} that is a time when viewing is started is calculated, and an unviewed scene is detected.

More specifically, for example, a user, a broadcast start time of the program that initiated the viewing using the mobile telephone 31, the viewing end time e _n to n-th a time when the viewing end, all predetermined program as the relative time in the time required for reproduction, it calculates the viewing end time Te _n.

Also, for example, the user can play all the programs based on the broadcast start time of a program that has been viewed using the mobile phone 31 and the viewing start time s _{n + 1} , which is the time when viewing has started n + 1 times. A viewing start time Ts _{n + 1} is calculated as a relative time in the required time.

  After the processing of step S264 is completed, the process proceeds to step S265, and the video / audio processing unit 193 of the playback processing unit 125 starts from the playback buffer memory 192 in which the playback program is temporarily recorded by the processing of step S262 or step S264. The reproduction program is read out, and the video signal and the audio signal as the reproduction program are supplied to the display unit 126 and the audio output unit 127, respectively, and the image corresponding to the video signal is displayed on the display unit 126, and the audio output unit 127 is displayed. To output a sound corresponding to the sound signal.

  Thereafter, the process is terminated.

  As described above, in the playback process of the HDD recorder 32 in FIG. 13, the HDD recorder 32 plays the predetermined program from the beginning of the unviewed scene based on the history information from the mobile phone 31. It is possible to seamlessly view an unviewed scene following the view scene viewed using the mobile phone 31.

  Note that the HDD recorder 32 may reproduce the unviewed scene at a predetermined speed such as double speed or triple speed.

  In the playback process in the HDD recorder 32 in FIG. 13, the HDD recorder 32 plays a predetermined program from the beginning of the unviewed scene. A predetermined program can be reproduced from the beginning.

  That is, FIG. 14 is a diagram showing a state in which the HDD recorder 32 plays a predetermined program from the beginning of a viewing scene a predetermined time before an unviewed scene.

  In the figure, the arrow extending in the right direction shown on the upper side indicates the relative time in the time required to play all the predetermined programs, and is surrounded by a rectangle shown in the center in the figure. Numbers 1 to 9 indicate scenes 2 to 9 of a predetermined program that are reproduced corresponding to the relative time in the time required to reproduce all the predetermined programs.

For example, the time when the user watches the predetermined program from the first scene to the scene 5 in real time while the predetermined program is being broadcast using the mobile phone 31 on the go, and finishes viewing the scene 5 At t ₀ , viewing ends.

Thereafter, after returning home, the user uses the HDD recorder 32 to start viewing from scene 3 reproduced at time t ₁ , which has already been viewed, and scenes 3 to 5 that are viewing scenes. , And scenes after the unviewed scene 6 subsequent to the scene 5 of the viewing scene can be viewed.

  As described above, since the predetermined program is reproduced from the viewing scene before the unviewed scene, the user can easily determine from which viewing scene the reproduced unviewed scene is continued. I can understand.

  Here, in the recording process of FIG. 7, the HDD recorder 32 starts a recording process for recording a predetermined program based on a command transmitted from the mobile phone 31. A predetermined program can be recorded on the HDD recorder 32 by making a timer reservation to record the program.

  Next, a program start information transmission process in which the HDD recorder 32 transmits program start information indicating that a predetermined program has been started will be described with reference to the flowchart of FIG.

  As a premise that this program start information transmission processing is performed, the user operates the operation unit 126 so that a predetermined program broadcast on a predetermined channel is recorded at a predetermined time, and the system controller 121 Based on the operation signal from the operation unit 126, the TV specific information of the program to be recorded and the recording start time to start recording are temporarily recorded in the built-in memory 121a.

  In step S371, the system controller 121 appropriately determines whether or not the time measured by the time measuring unit that measures time is the recording start time temporarily recorded in the built-in memory 121a. Until the recording start time is determined, the process of step S371 is repeated.

  If it is determined in step S371 that the time counted is the recording start time, the process proceeds to step S372, and the system controller 121 controls the recording processing unit 123 to start recording a predetermined program. Then, the process proceeds to step S373, and the system controller 121 initializes the variable m to the value 0.

  Thereafter, the system controller 121 obtains the specific information for one seg by converting the specific information for TV that specifies the predetermined program that has started recording into the specific information for one seg, and the process is step S374. Proceed to

  As with the mobile phone 31, the system controller 121 corresponds to TV specific information and one-segment specific information that specifies a channel that broadcasts the same program as the program specified by the TV specific information. It is assumed that the specific information for TV is converted into the specific information for one seg using the attached specific information table.

  In step S374, the system controller 121 generates program start information, supplies it to the communication unit 128 together with the acquired one-segment specific information, and controls the communication unit 128 to obtain the program start information and the one-segment specific information. Then, it is transmitted to the mobile phone 31.

  After the process of step S374 is completed, the process proceeds to step S375, and the communication unit 128 operates within the predetermined time from the time when the program start information and the specific information for one seg are transmitted according to the control of the system controller 121. From 31, it is determined whether or not a response indicating that the program start information and the specific information for one seg have been normally received has been received.

  If it is determined in step S375 that the program start information and the response indicating that the one-segment specific information has been normally received have been received, the process ends.

  On the other hand, if it is determined in step S375 that a response indicating that the program start information and the specific information for one-segment broadcasting have been normally received has not been received, the process proceeds to step S376.

  In step S376, the system controller 121 adds the value 1 to the variable m and sets the resulting added value as a new variable m. Then, the process proceeds to step S377, where the variable m is greater than the threshold Th_m. It is determined whether it is also large. Here, the threshold value Th_m represents the number of times that the mobile phone 31 transmits the program start information and the specific information for 1Seg until it is normally received. For example, the threshold value Th_m is a value that is set in advance when the HDD recorder 32 is manufactured at the factory. It is.

  If it is determined in step S377 that the variable m is not greater than the threshold value Th_m, the process returns to step S374, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S377 that the variable m is greater than the threshold value Th_m, the process is terminated.

  Next, referring to the flowchart of FIG. 16, when the HDD recorder 32 performs the program start information transmission process of FIG. 15, the mobile phone 31 receives the program start information from the HDD recorder 32. The reception process will be described.

  This program start information reception process is started, for example, when the HDD recorder 32 transmits program start information and one-segment specific information in step S374 of FIG.

  At this time, in step S411, the communication unit 71 receives the program start information and the specific information for one seg transmitted from the HDD recorder 32 according to the control of the system controller 61, and supplies them to the system controller 61. The process proceeds to step S412.

  In step S412, the system controller 61 determines whether the program start information and the one-segment specific information supplied from the communication unit 71 are error-free information, that is, the communication unit 71 determines whether the program start information and the one-seg It is determined whether or not the specific information is normally received.

  If it is determined in step S412 that the program start information and the one-segment specific information cannot be normally received, in step S374 in FIG. 15, the HDD recorder 32 again determines the program start information and the one-segment specific information. After waiting for the information to be transmitted, the process returns to step S411, and thereafter the same process is repeated. In the process of step S374 in FIG. 15, when the HDD recorder 32 no longer transmits the program start information and the specific information for one seg to the mobile phone 31, that is, in step S377 in FIG. If it is determined that it is greater than Th_m, the process of step S412 is terminated, and then the process is terminated.

  On the other hand, if it is determined in step S412 that the program start information and the one-segment specific information have been normally received, the process proceeds to step S413, and the system controller 61 normalizes the program start information and the one-segment specific information. A response indicating that it has been received is generated, supplied to the communication unit 71, and supplied to the HDD recorder 32. That is, in step S413, the communication unit 71 transmits a response indicating that the program start information and the one-segment specific information have been normally received according to the control of the system controller 61, and the process proceeds to step S414.

  In step S414, the system controller 61 controls the video / audio processing unit 65 based on the program start information from the communication unit 71, and causes the audio output unit 67 to store the program specified by the specific information for one seg for a certain period. A sound indicating that the broadcast has started is output. Instead of outputting sound, a vibration function provided in the mobile phone 31 may be used as means for notifying the user that the broadcast of the program specified by the specific information for 1Seg has started. .

  Thereafter, the process proceeds from step S414 to step S415, and the system controller 61 views the program specified by the specific information for one seg within a certain period during which audio is output in the process of step S414. As described above, the one-segment viewing of the program specified by the one-segment specific information within a certain period based on whether or not the operation unit 68 of the mobile phone 31 has been operated, that is, based on the operation signal from the operation unit 68. It is determined whether or not the mode is set.

  If it is determined in step S415 that the one-segment viewing mode has been set within a certain period, the process proceeds to step S416, and the mobile phone 31 displays the program specified by the received one-segment specific information. The process is terminated.

  That is, in step S416, the mobile phone 31 performs the process described with reference to FIG. 9, and then the process ends.

  On the other hand, when it is determined in step S415 that the one-segment viewing mode has not been set within a certain period of time, the process proceeds to step S417, and the system controller 61 determines that the one-segment segment-specific information from the communication unit 71 is present. Then, the audio / video processing unit 65 is controlled, and an icon or the like indicating that the program specified by the one-segment specific information is started is displayed on the display unit 66, and the process proceeds to step SS418.

  In step S418, under the control of the system controller 61, the tuner 63 causes the ring buffer 64 to temporarily record the program specified by the specific information for one seg broadcast within the latest predetermined time. Is terminated.

  After that, when the user operates the operation unit 68 of the mobile phone 31 so as to set the one-segment viewing mode, the mobile phone 31 outputs the predetermined program temporarily recorded in the ring buffer 64 in step S418. .

  Here, even if the user cannot set the mobile phone 31 to the one-segment viewing mode when the predetermined program is started, the ring buffer 64 is identified by the one-segment identification information by the processing in step S418. Since the program to be recorded is temporarily recorded from the beginning, if the capacity of the program temporarily recorded in the ring buffer 64 is smaller than the recording capacity of the ring buffer 64 when the one-segment viewing mode is set, Since the program specified by the specific information for 1Seg is temporarily recorded in the ring buffer 64 from the beginning until the 1Seg viewing mode is set, the user can view the program from the beginning.

  As described above, when the broadcast of the program reserved for the timer at the home is started by the program start information transmission process of FIG. 15 and the program start information reception process of FIG. 16, the program is transmitted from the HDD recorder 32 to the mobile phone 31. Since the mobile phone 31 is to notify the start of the broadcast and the mobile phone 31 is to output a sound to notify the user of the start of the broadcast of the program, the user starts the broadcast of the timer reserved program by the mobile phone 31. You can easily know what will be done.

  Next, another viewing history process performed by the mobile phone 31 will be described with reference to the flowchart of FIG.

  This other viewing history process is started, for example, when the user operates the operation unit 68 to view a predetermined program using the mobile phone 31. At this time, the system controller 61 is supplied with an operation signal from the operation unit 68 according to the user's operation. The system controller 61 receives the tuner 63 and the video / audio processing unit based on the operation signal from the operation unit 68. 65 is controlled.

  In step S451, the system controller 61 determines whether or not history information of a predetermined program that the user starts to watch is recorded in the viewing information recording unit 70 in which the history information is recorded. It is determined whether or not there is an interrupted section (unviewed scene), which is a section in which viewing is interrupted, which is made by starting and ending.

  In step S451, when it is determined that the history information of the predetermined program that the user starts to watch is not recorded in the viewing information recording unit 70, that is, when it is determined that there is no interruption section, the process is as follows. Proceeding to step S453, in steps S453 to S459, the same processing as in steps S131 to S137 of FIG. 9 is performed.

  Thereafter, the process proceeds from step S459 to step S460, and the tuner 63, according to control of the system controller 61, receives a predetermined program received during a predetermined time period from when the one-segment broadcasting radio wave is received by the antenna 62. Until the next time another viewing history process is performed, the temporary recording in the ring buffer 64 is continued as appropriate. Then, when another viewing history process is performed next time, the other viewing history process performed this time is ended.

  On the other hand, if it is determined in step S451 that history information of a predetermined program that the user starts to watch is recorded in the viewing information recording unit 70, that is, if it is determined that there is an interrupted section, the processing is performed. In step S452, the system controller 61 determines whether the user has operated the operation unit 68 so as to view the program from the interruption section based on the operation signal from the operation unit 68, or the program from the currently broadcasted program. It is determined whether or not the operation unit 68 has been operated so as to watch the video, that is, whether or not the interruption section is to be reproduced.

  If it is determined in step S452 that the interrupted section is not reproduced, the process proceeds to step S453, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S452 that the interrupted section is to be reproduced, the process proceeds to step S455. In steps S455 to S459, the mobile phone 31 starts viewing the predetermined program from where it last finished viewing. Start.

  That is, in step S455, the same processing as in step S133 of FIG. 9 is performed, the processing proceeds to step S456, and the video / audio processing unit 65 performs step S460 in other viewing history processing last time according to the control of the system controller 61. The predetermined program temporarily recorded in the ring buffer 64 by the above process is read, and the process proceeds to step S457, and thereafter the same process is repeated.

  As described above, since the interruption section generated by interrupting the viewing last time can be reproduced, the user can start viewing from the beginning of the interruption section generated last time, for example. Therefore, the program can be viewed seamlessly by the mobile phone 31 regardless of the HDD recorder 32 at home.

  Here, in the information processing system of FIG. 1, the user can seamlessly view an unviewed scene of a program started to be viewed by the mobile phone 31 by using the HDD recorder 32 at home while away from home. However, on the contrary, the user can view the program that the user was watching at home from the television receiver 33 seamlessly on the go.

  FIG. 18 is a block diagram illustrating a configuration example of such an information processing system.

  The information processing system in FIG. 18 includes a mobile phone 31 and a television receiver 33.

  The cellular phone 31 is configured in the same manner as the cellular phone 31 of FIG. 1, and transmits a request signal for requesting predetermined data to the television receiver 33 and transmits the data corresponding to the request signal to the television receiver. From the machine 33.

  The television receiver 33 receives a request signal from the mobile phone 31 and transmits data corresponding to the request signal to the mobile phone 31.

  FIG. 19 is a block diagram showing a detailed configuration example of the television receiver 33 of FIG.

  The television receiver 33 includes a system controller 261 having a built-in memory 261a, an antenna 262, a tuner 263, a buffer 264, a video / audio processing unit 265, a display unit 266, an audio output unit 267, a ring buffer 268, an operation unit 269, and a communication. Part 270.

  For example, the system controller 261 controls the tuner 263, the video / audio processing unit 265, and the communication unit 270 in accordance with the operation of the operation unit 269 operated by the user.

  Further, the system controller 61 reads the ring buffer data from the ring buffer 268 in which the ring buffer data corresponding to the latest predetermined time in the predetermined program is temporarily recorded, and supplies the ring buffer data to the communication unit 270.

  The memory 261a is a memory used for a work area used for processing performed by the system controller 261.

  The antenna 262 receives a broadcast wave of TV broadcast and supplies a corresponding RF signal to the tuner 263.

  The tuner 263 demodulates the RF signal of a predetermined channel from the TV broadcast RF signal supplied from the antenna 262, and appropriately supplies the audio signal and the video signal obtained as a result to the buffer 264 for temporary recording.

  The buffer 264 temporarily records the audio signal and the video signal supplied from the tuner 263.

  The video / audio processing unit 265 reads the video signal and the audio signal from the buffer 264 in which the video signal and the audio signal are temporarily recorded, and supplies them to the display unit 266 and the audio output unit 267, respectively.

  In addition, the video / audio processing unit 265 causes the display unit 266 to display a video corresponding to the video signal supplied to the display unit 266. Further, the video / audio processing unit 265 causes the audio output unit 267 to output audio corresponding to the audio signal supplied to the audio output unit 267.

  Further, the video / audio processing unit 265 reads out the video signal and the audio signal from the buffer 264 in which the video signal and the audio signal are temporarily recorded, and appropriately supplies the video signal and the audio signal to the ring buffer 268 to be temporarily recorded.

  The display unit 266 displays a video corresponding to the video signal supplied from the video / audio processing unit 265.

  The audio output unit 267 outputs audio corresponding to the audio signal supplied from the video / audio processing unit 265.

  The ring buffer 268 temporarily records the video signal and audio signal supplied from the video / audio processing unit 265.

  The operation unit 269 is an operation button or a power button provided on the television receiver 33. When the user operates the operation unit 269, an operation signal corresponding to the operation by the user is supplied to the system controller 261. Note that the operation unit 269 is not necessarily provided in the television receiver 33, and may be provided, for example, in a remote controller (not shown) that operates the television receiver 33. When the unit 269 is operated, an operation signal corresponding to the operation by the user is supplied to the system controller 261 by wireless such as infrared rays.

  The communication unit 270 transmits the ring buffer data and the like supplied from the system controller 261 to the mobile phone 31 via wireless such as infrared rays. The communication unit 270 receives information supplied from the mobile phone 31 and supplies the information to the system controller 261.

  Next, referring to the flowchart of FIG. 20, the television receiver 33 transmits ring buffer data in response to a request signal from the mobile phone 31 that requests the ring buffer data temporarily recorded in the ring buffer 268. The ring buffer data transmission processing will be described.

  In step S511, the antenna 262 receives a broadcast wave of TV broadcast and supplies a corresponding RF signal to the tuner 263. The tuner 263 receives a predetermined channel from the RF signal of TV broadcast supplied from the antenna 262. The RF signal is demodulated, and the resulting audio signal and video signal are supplied to the buffer 264 for temporary recording.

  In step S511, the video / audio processing unit 265 reads the video signal and the audio signal, which are temporarily recorded in the buffer 264, as appropriate, and supplies them to the display unit 266 and the audio output unit 267, respectively, according to the control of the system controller 261. Then, the display unit 266 displays an image corresponding to the video signal, and the audio output unit 267 outputs audio corresponding to the audio signal.

  The processing proceeds from step S511 to step S512, and the video / audio processing unit 265 further supplies the video signal and audio signal read from the buffer 264 to the ring buffer 268 to temporarily record them, and the processing proceeds to step S513. move on.

  Thereby, the latest predetermined time in the program represented by the video signal and the audio signal is recorded in the ring buffer 268.

  In step S513, the communication unit 270 determines whether or not a request signal for requesting ring buffer data temporarily recorded in the ring buffer 268 has been received.

  If it is determined in step S513 that the request signal has not been received, the process returns to step S511, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S513 that the request signal has been received, the process proceeds to step S514, the system controller 261 initializes the variable i to the value 0, and the process proceeds to step S515, where the ring buffer data Is read from the ring buffer 268 temporarily recorded, and converted into a predetermined format that can be reproduced by the mobile phone 31.

  In step S515, the system controller 261 supplies the ring buffer data converted into a predetermined format to the communication unit 270 and causes the mobile phone 31 to transmit the ring buffer data.

  That is, in step S515, the communication unit 270 transmits the ring buffer data (converted into a predetermined format) supplied from the system controller 261 to the mobile phone 31.

  After the process of step S515 ends, the process proceeds to step S516, and the communication unit 270 sends a response indicating that the ring buffer data has been normally received within a predetermined time after transmitting the ring buffer data to the mobile phone. It is determined whether or not the mobile phone 31 has received the ring buffer data from the communication unit 270 normally.

  If it is determined in step S516 that the mobile phone 31 has received a response indicating that the ring buffer data has been normally received within a predetermined time after transmitting the ring buffer data, the process proceeds to step S520. In accordance with the control of the system controller 261, the video / audio processing unit 265 causes the display unit 266 to display a message indicating that the ring buffer data has been normally received by the mobile phone 31, and the processing ends.

  On the other hand, if it is determined in step S516 that a response indicating that the ring buffer data has been normally received has not been received from the mobile phone 31 within a predetermined time after transmitting the ring buffer data, Proceeding to step S517, the system controller 261 adds the value 1 to the variable i, and sets the resultant addition value as the value of the new variable n. Then, the process proceeds to step S518.

  In step S518, the system controller 261 determines whether the variable i is larger than the threshold value Th_i. Here, the threshold value Th_i represents the number of times the ring buffer data is transmitted until the mobile phone 31 normally receives it, and is, for example, a value set in advance when the television receiver 33 is manufactured at the factory.

  If it is determined in step S518 that the variable i is not greater than the threshold value Th_i, the process returns to step S515, and thereafter the same process is repeated.

  On the other hand, if it is determined in step S518 that the variable i is larger than the threshold value Th_i, the process proceeds to step S519, and the video / audio processing unit 265 performs the ring by the mobile phone 31 according to the control of the system controller 261. A display to the effect that the buffer data has not been received normally is displayed on the display unit 266, and the process is terminated.

  Next, ring buffer data reception processing in which the mobile phone 31 receives ring buffer data from the television receiver 33 will be described with reference to the flowchart of FIG.

  This ring buffer data reception process is started when the user operates the operation unit 68 of the mobile phone 32 so as to record a predetermined program having the same content as the program output from the television receiver 33. Is done.

  At this time, in step S581, the system controller 61 records a predetermined program having the same content as the program output from the television receiver 33, based on the operation signal from the operation unit 68. That is, in step S581, a predetermined program supplied from the antenna 62 to the ring buffer 64 via the tuner 63 is read and supplied to the moving image content recording unit 69 for recording.

  Thereafter, when the user operates the operation unit 68 to transmit a request signal for requesting ring buffer data temporarily recorded in the ring buffer 268 of the television receiver 33, the communication unit 71 controls the system controller 61. The request signal is transmitted to the mobile phone 33 according to the above.

  Thereafter, the process proceeds from step S581 to step S582, and the communication unit 71 receives the ring buffer data from the television receiver 33 transmitted by the process of step S515 in FIG. 20 and supplies the ring buffer data to the system controller 61. The processing proceeds to step S583, and the system controller 61 determines whether or not the ring buffer data supplied from the communication unit 71 is error-free data, that is, the communication unit 71 receives the ring buffer data normally. Determine whether or not.

  If it is determined in step S583 that the ring buffer data could not be received normally, in step S515 in FIG. 20, the television receiver 33 waits for the ring buffer data to be transmitted again. Returning to step S582, the same processing is repeated thereafter. In the process of step S515 in FIG. 20, when the television receiver 33 no longer transmits ring buffer data to the mobile phone 31, that is, in step S518 in FIG. 20, the variable i is larger than the threshold value Th_i. Is determined, the process of step S583 is terminated, and then the process is terminated.

  On the other hand, if it is determined in step S583 that the ring buffer data has been normally received, the process proceeds to step S584, and the system controller 61 uses the ring buffer data supplied from the communication unit 71 as the moving image content recording unit 69. To be recorded.

  After the process of step S584 ends, the process proceeds to step S585, and the system controller 61 supplies the communication unit 71 with a response indicating that the ring buffer data has been normally received, and transmits the response to the television receiver 33. Then, the process is terminated.

  Next, with reference to the flowchart of FIG. 22, a description will be given of a reproduction process in which the mobile phone 31 reproduces a predetermined program after the ring buffer data reception process of FIG.

  The reproduction processing by the cellular phone 31 is performed following the one-segment viewing mode in which the user views the program currently broadcast, or the ring buffer data obtained in step S582 in FIG. 21 and the ring buffer data. The program is started when the operation unit 68 of the mobile phone 31 is operated so as to set the follow-up playback mode in which the program recorded in step S581 of 21 is played back at the double speed or triple speed.

  At this time, in step S621, the system controller 61 determines, based on the operation signal from the operation unit 68, whether the mode of the mobile phone 33 is set to the one-segment viewing mode or the chasing playback mode.

  If it is determined in step S621 that the chasing playback mode has been set, the process proceeds to step S622, and the system controller 61 records the moving image content recording unit 69 in which the ring buffer data and the program following the ring buffer data are recorded. Then, the ring buffer data and the program following the ring buffer data are read out, supplied to the video / audio processing unit 65, and the video / audio processing unit 65 is controlled to be played back at, for example, double speed.

  Thereafter, in step S622, when the user operates the operation unit 68 to change from the chasing playback mode to the one-segment viewing mode, the process proceeds to step S623.

  On the other hand, if it is determined in step S621 that the chasing playback mode has not been set, that is, the one-segment viewing mode has been set, the process proceeds to step S623, and the mobile phone 31 performs the predetermined program currently being broadcast. Is output.

  That is, in step S623, the tuner 63 demodulates the RF signal of a predetermined channel from the RF signal from the antenna 62 according to the control of the system controller 61, and the audio signal and video signal obtained as a result are converted into the ring buffer 64. To be temporarily recorded.

  In step S623, the video / audio processing unit 65 reads the audio signal and the video signal temporarily recorded in the ring buffer 64, and supplies the video signal and the audio signal to the display unit 66 and the audio output unit 67, respectively. The display unit 66 displays an image corresponding to the video signal, and the audio output unit 67 outputs audio corresponding to the audio signal.

  Thereafter, the process proceeds from step S623 to step S624, and the system controller 61 determines whether or not an operation signal for instructing the end of the output of the program started by the user is supplied from the operation unit 68, that is, the user It is determined whether or not the operation unit 68 has been operated so as to end the viewing of the program that has started viewing.

  If it is determined in step S624 that viewing of the program that the user has started viewing has not ended, the processing returns to step S623, and the same processing is repeated thereafter.

  On the other hand, if it is determined in step S624 that viewing of the program that the user has started viewing has ended, the process ends.

  As described above, the mobile phone 32 records a program having the same content as the program output from the television receiver 33 in the ring buffer data reception process of FIG. Since the scene that could not be viewed of the program output from the John receiver 33 can be received as ring buffer data from the television receiver 33, the user can use the mobile phone 32 to The program can be viewed from a scene where the program output from the receiver 33 could not be viewed. Therefore, the user can seamlessly view the continuation of the program that was viewed using the television receiver 33 using the mobile phone 31.

  Next, the series of processes described above can be executed by dedicated hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software can execute various functions by installing a so-called embedded computer or various programs. For example, it is installed from a program storage medium in a general-purpose personal computer.

  FIG. 23 is a block diagram illustrating a configuration example of a computer that executes the above-described series of processing by a program.

  A CPU (Central Processing Unit) 901 executes various processes according to a program recorded in a ROM (Read Only Memory) 902 or a storage unit 908. A RAM (Random Access Memory) 903 appropriately stores programs executed by the CPU 901, data, and the like. The CPU 901, ROM 902, and RAM 903 are connected to each other by a bus 904.
