  However, the user cannot grasp the ratio of the recording time to the program airing time (hereinafter also referred to as the recording rate) only by the information presented from the program recording device disclosed in Patent Document 1. Further, the recording / reproducing system disclosed in Patent Document 2 can display the recorded time with respect to the scheduled recording time designated by the user, but cannot display the recording rate.

  For this reason, a user who uses the program recording device disclosed in Patent Document 1 or the recording / reproducing system disclosed in Patent Document 2 can record a program of, for example, a program broadcast time of 30 minutes for only 15 minutes. In this case, in order to know that 50% of the aired program has been recorded, it is necessary for the user himself / herself to confirm the recording rate by checking the program guide.

  When recording with reference to a database such as a program guide in advance, it is possible to make a reservation designation from the broadcast start time to the broadcast end time of the program, and it is easy to keep the recording rate at 100%. When the user determines that recording is necessary while viewing the program, the recording start time is delayed from the broadcast start time. In this case, in order to know how much of the program broadcast time can be recorded, it is necessary to refer to the program table and the like as described above.

  Also, since most of the program could not be recorded because the recording was started from the second half of the aired program, and the user decided to record the rebroadcast, the user waits for the rebroadcast of the desired program and makes a reservation for recording again There was a need. In this case, if the period until the rebroadcast is long, it is difficult to continue the investigation of the date and time when the rebroadcast is performed.

  Also, when watching a rebroadcast, it is necessary to know the previous recorded part in order not to watch the previously recorded part in an overlapping manner. It was difficult to memorize the recorded part accurately.

  Also, if the previous recorded program remains in the recording medium during rebroadcast recording, a part of the program is recorded in duplicate, and the consumption of the recording medium increases.

  In view of the above problems, an object of the present invention is to provide a program recording apparatus that can determine the ratio of recording time to program broadcast time.

  In order to achieve the above object, in the program recording apparatus according to the present invention, recording means for recording a broadcast program, and information related to the broadcast program recorded by the recording means, and at least a program broadcast time can be specified.

Convenience can be improved by displaying the ratio of the recording time with respect to the program broadcast time to the user, or by using it as a material for determining whether to record the rebroadcast.

  An embodiment of the present invention will be described with reference to the drawings. An example of the configuration of a program recording apparatus according to the present invention is shown in FIG.

  The program recording apparatus 1 according to the present invention is connected to an external database 7 storing information relating to broadcast programs, and a monitor 8 comprising a display and a speaker.

  The program recording device 1 includes a tuner 2 that receives a broadcast program, a control device 3 that controls the entire program recording device, an interface circuit 4 that communicates with an external database 7, and an input device 5 that inputs a user command. The recording / reproducing apparatus 6 has a function of recording a broadcast program on a recording medium and a function of reproducing a broadcast program recorded on the recording medium. The recording medium may be detachable from the program recording apparatus 1 or may be built in the program recording apparatus 1.

  Hereinafter, a plurality of embodiments of the operation of the program recording apparatus 1 will be described. First, the first embodiment will be described.

  For example, while the user is viewing 8ch on August 16, 2003, as shown schematically in FIG. 2 (a), the user starts recording on the input device 5 at 19:20 and inputs at 19:50. It is assumed that a recording end operation is performed on the device 5. FIG. 2B shows an 8ch broadcast program table from August 1st, 2003 18:00 to 21:00.

  The input device 5 transmits the user's operation content to the control device 3, and the control device 3 records and reproduces the 8-channel broadcast program received by the tuner 2 according to the user's operation content from 19:20 to 19:50. 6 to record. When the recording by the recording / reproducing apparatus 6 is completed, the control apparatus 3 uses the interface circuit 4 to store broadcast program information belonging to 8ch on August 16, 2003 at 19:20 from the program information stored in the external database 7. To get. Note that the broadcast program information acquired by the control device 3 needs to include at least information capable of specifying the program broadcast time. Here, the control device 3 acquires information that the program title is “quiz swiftly”, the program broadcast start time is 19:00, and the program broadcast end time is 20:00.

  Then, the control device 3 obtains the recording time from the recording start time and the recording end time, obtains the program broadcast time from the previously acquired program broadcast start time and the program broadcast end time, and calculates the recording rate from the recording time and the program broadcast time. calculate. After calculating the recording rate, the control device 3 associates the recording rate with other information (program title, recording date / time, channel, recording time, etc.) of the recorded broadcast program and records it on the recording medium by the recording / playback device 6. At the same time, information on the recorded program including the recording rate is output to the monitor 8. The monitor display at this time is shown in FIG. By displaying the recording rate on the monitor in this way, the user can grasp the recording rate without referring to the program guide or the like.

  Note that the recording rate may be displayed in a graph as shown in FIG. Thereby, the user can grasp the recording rate intuitively. Further, as shown in FIG. 4B, the recording rate may be graphed, and the recording rate graph may be changed in accordance with the position of the recording location in the program broadcast time frame. In FIG. 4B, A corresponds to the program broadcast time, B corresponds to the recording time, and C corresponds to the time from the start of broadcasting to the start of recording. Further, when the recorded broadcast program is reproduced, the recording rate is graphed as shown in FIG. 4 (c), and the recording rate graph is changed according to which position in the program broadcasting time frame the recording location is. In addition, it may be displayed at which position of the recorded part the reproduced part. In addition, if playback is in progress, the current playback location may be displayed as a pointer. In FIG. 4 (c), D corresponds to a reproduced position and E corresponds to a currently reproduced position. The display screen shown in FIG. 4C is displayed on a monitor by combining with the playback screen when, for example, display of a list management table of recorded programs is requested by a user operation during playback of a recorded broadcast program.

  Next, a second embodiment will be described with reference to an operation flowchart of FIG. First, the user performs a recording rate threshold setting operation on the input device 5. The input device 5 transmits the user operation content to the control device 3, and the control device 3 stores the threshold value in an internal memory (not shown in FIG. 1) according to the user operation content (step S10).

  Thereafter, when the user performs a recording start operation and a recording end operation on the input device 5, the input device 5 transmits the user's operation content to the control device 3, and the control device 3 uses the tuner 2 in accordance with the user's operation content. The received broadcast program is recorded by the recording / reproducing apparatus 6 (step S20).

  When the recording by the recording / reproducing apparatus 6 is completed, the control apparatus 3 acquires information on the broadcast program recorded in step S20 from the program information stored in the external database 7 through the interface circuit 4 (step S30). Note that the broadcast program information acquired by the control device 3 needs to include at least information capable of specifying the program broadcast time.

  Then, the control device 3 obtains the recording time from the recording start time and the recording end time, obtains the program broadcast time from the previously acquired program broadcast start time and the program broadcast end time, and calculates the recording rate from the recording time and the program broadcast time. Calculate (step S40).

  In subsequent step S50, the control device 3 determines whether or not the recording rate calculated in step S40 is equal to or greater than the threshold set in step S10. If the recording rate is equal to or higher than the threshold (Yes in step S50), the series of operations is terminated. On the other hand, if the recording rate is less than the threshold (No in step S50), the control device 3 re-broadcasts the broadcast program recorded in step S20 from the program information stored in the external database 7 through the interface circuit 4. Is determined to determine whether or not the rebroadcast schedule has been acquired (step S60). If the rebroadcast schedule can be acquired (Yes in step S60), the control device 3 uses the monitor 8 to record information on the broadcast program recorded in step S20 (program title, recording date and time, channel, recording time, recording rate, etc.). Output (step S70).

  In subsequent step S80, the control device 3 causes the monitor 8 to display a message asking the user whether or not to perform rebroadcast recording. Thereafter, the control device 3 determines whether or not the user has performed an operation for requesting re-broadcast recording reservation to the input device 5 (step S90). If the user does not perform an operation for requesting a recording reservation for rebroadcast (No in step S90), the series of operations ends. On the other hand, if the user performs an operation to request a rebroadcast recording reservation (Yes in step S90), the control device 3 sets a recording reservation at the rebroadcast date and time based on the rebroadcast schedule acquired earlier ( After that, the recording / reproducing apparatus 6 records the rebroadcast (step S110), and when the rebroadcast recording ends, the series of operations is terminated.

  According to the operation of the second embodiment, when the recording rate is equal to or higher than the threshold value, the program recording apparatus 1 automatically determines that rebroadcast recording is not performed, so the user needs to record rebroadcast. It is not necessary to judge whether or not. When the recording rate is less than the threshold, the user needs to determine whether or not rebroadcast recording is necessary, but information on the broadcast program recorded by the operation in step S70 is displayed on the monitor. Therefore, it is possible to easily determine whether or not rebroadcast recording is necessary. Therefore, although it is desirable to provide step S70, it may be omitted.

  Next, a third embodiment will be described with reference to an operation flowchart of FIG. In FIG. 6, the same steps as those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof is omitted. The flowchart of FIG. 6 is obtained by removing steps S70 to S90 from the flowchart of FIG.

  In the third embodiment, if the rebroadcast schedule can be acquired (Yes in step S60), the control device 3 automatically sets a recording reservation at the rebroadcast date and time based on the acquired rebroadcast schedule (step S100). Then, the recording / reproducing apparatus 6 records the rebroadcast (step S110), and when the rebroadcast recording ends, the series of operations ends.

  According to the operation of the third embodiment, the program recording apparatus 1 automatically determines that rebroadcast recording is not performed when the recording rate is equal to or greater than the threshold, and rebroadcasting is performed when the recording rate is less than the threshold. Since the program recording apparatus 1 automatically determines that recording is to be performed, the user does not have to determine at all whether or not rebroadcast recording is necessary.

  Further, the step group shown in FIG. 7 may be added to the above-described operation flowchart of FIG. 5 or the operation flowchart of FIG. Hereinafter, the operation of the step group shown in FIG. 7 will be described.

  When the rebroadcast recording in step S110 ends, the control device 3 displays on the monitor 8 that the rebroadcast recording is complete (step S120). By notifying the completion of the rebroadcast recording, the user can recognize that the rebroadcast recording has been completed even if the user has forgotten to rebroadcast for a long time. .

  Then, the control device 3 outputs information on the broadcast program recorded in step S20 (program title, recording date and time, channel, recording time, recording rate, etc.) to the monitor 8 (step S130). Since this information can be used as a material for determining whether or not to rebroadcast, the user can easily determine whether or not to rebroadcast. Therefore, although it is desirable to provide step S130, it may be omitted.

  In subsequent step S140, the control device 3 determines whether or not the user has performed an operation requesting the input device 5 to replay the rebroadcast (step S140). If the user does not perform an operation for requesting reproduction of rebroadcast (No in step S140), the series of operations ends. On the other hand, if the user performs an operation for requesting the rebroadcast reproduction (Yes in step S140), the control device 3 causes the recording / reproduction device 6 to reproduce the rebroadcast (step S150), thereby reproducing the rebroadcast. When is finished, a series of operations are terminated.

  8 may be added to the above-described operation flowchart of FIG. 5 or the operation flowchart of FIG. Hereinafter, the operation of the step group shown in FIG. 8 will be described. In FIG. 8, the same steps as those in FIG. 7 are denoted by the same reference numerals, and detailed description thereof is omitted.

  If it is determined in step S140 that the user has performed an operation to request rebroadcast reproduction (Yes in step S140), the control device 3 causes the recording / reproduction device 6 to start rebroadcast reproduction (step S160). Then, the control device 3 determines whether or not the playback location has reached the previous recording start time (step S170).

  It is possible to determine where the previous recording start time is from the recording start time in the recording in step S20 and the broadcast start time acquired in step S30. For example, when the threshold of the recording rate is set to 80% and the user is viewing 8ch on August 16, 2003, as shown schematically in FIG. The recording start operation is performed, and the recording end operation is performed on the input device 5 at 19:50. FIG. 2B shows an 8ch broadcast program table from August 1st, 2003 18:00 to 21:00. In this case, from the recording start time 19:20 and the broadcast start time 19 o'clock, the previous recording start time is determined to be the time when 20 minutes have elapsed from the start of the broadcast.

  If the playback location reaches the previous recording start time (Yes in step S170), the control device 3 displays a notification that the previous recording start time has been reached on the monitor 8 (step S180), and the playback is performed. When playback is stopped in response to a playback stop request from the user, a series of operations ends.

  When the step group in FIG. 8 is added, when the playback part reaches the previous recording start time during rebroadcast playback, a notification to that effect is displayed on the monitor, so that the user can accurately grasp the previous recording start time. it can. As a result, it is possible to prevent the previously recorded portion from being viewed in an overlapping manner. Since the part after the previous recording start time is also recorded at the time of rebroadcast recording, the part after the previous recording start time continues if the user does not stop playback even if notified in step S180. Can watch.

  Further, in the operation flowchart of FIG. 5 or the operation flowchart of FIG. 6 described above, step S100 may be a step for setting a recording reservation except for the portion after the previous recording start time. As a result, when the rebroadcast recording is performed, portions after the previous recording start time are not recorded redundantly.

  For example, when the threshold of the recording rate is set to 80% and the user is viewing 8ch on August 16, 2003, as shown schematically in FIG. The recording start operation is performed, and the recording end operation is performed on the input device 5 at 19:50. FIG. 2B shows an 8ch broadcast program table from August 1st, 2003 18:00 to 21:00. In this case, from the recording start time 19:20 and the broadcast start time 19 o'clock, the previous recording start time is determined to be the time when 20 minutes have elapsed from the start of the broadcast. Therefore, the recording reservation is set except for the portion after 20 minutes after the start of broadcasting. That is, the recording reservation setting is set for only 20 minutes from the start of broadcasting.

  Furthermore, when step S100 is set as a step for setting recording reservation except for the portion after the previous recording start time, the step group shown in FIG. 9 may be added to the operation flowchart of FIG. 5 or the operation flowchart of FIG. 9, the same parts as those in FIG. 7 are denoted by the same reference numerals, and detailed description thereof is omitted. When the reproduction of the rebroadcast in step S150 ends, the control device 3 displays on the monitor 8 a notification that the part after the previous recording start time is not recorded (step S190), and ends the series of operations. .

  The operation flow shown in FIG. 9 allows the user to know the reason why the rebroadcast recording ended in the middle of the program.

  In the second embodiment or the third embodiment, at step S70, at step S130, the monitor display shown in FIG. 3, FIG. 4 (a), or FIG. When the display of the program list management table is requested, the monitor display shown in FIG. 3, FIG. 4 (a), FIG. 4 (b), or FIG. 4 (c) may be performed.

  In the second embodiment or the third embodiment, it is preferable not to perform the determination in step S50 for the recorded rebroadcast program.
