Description

  The present invention relates to an automatic recording apparatus that automatically extracts recommended programs to be recorded from broadcast programs and automatically records them.

  A conventional device that automatically extracts recommended programs to be recorded calculates the recommended degree of each program to be broadcast based on past recording history information, and records programs whose recommended degree value is greater than or equal to the reference value. It is determined that the program is a recommended program and is automatically extracted (see Patent Document 1).

Japanese Patent Laying-Open No. 2005-117138 (page 3-8, FIG. 1)

  In the conventional recommended recording program extracting device disclosed in Patent Document 1, the recommended degree value is expressed as a comprehensive recommended recording value. For example, if a program whose genre is music is recorded at a very high frequency, the recommended total recording value of the program whose genre is music increases, and many music programs are extracted as recommended recording programs. In the case where a program of a genre other than music is hardly recorded, it is considered that a program whose overall recording recommended value is a reference value or more is only a music program. For example, in the recording history, when there is only one program whose genre is animation and all other program genres are music, the recommended recording program is only music depending on the standard value of the recommended total recording value set. It can happen. In this case, there is a problem that if the recording reservation of the program corresponding to the next broadcast of the music program held in the recording history is forgotten, the music program is not extracted as a recommended recording program.

  In addition, the conventional recommended recording program extracting device disclosed in Patent Document 1 cannot automatically execute the recommended recording program by simply extracting the recommended recording program. For this reason, even if a program to be recorded is extracted, there is a problem that the recording is not performed unless the user performs an operation of reserving a recording of the extracted recommended recording program.

  Furthermore, in the case of automatically recording a program extracted by the method proposed by the conventional recording recommended program extracting apparatus disclosed in Patent Document 1, the user's program is included in the automatically recorded program. Even if a program that does not match your preferences is included, the automatically recorded information will be reflected in the recording history, so the accuracy of the degree of match with the user's preferences will deteriorate when the next recommended recording program is extracted There was a problem.

  The present invention has been made to solve the above-mentioned problems, and even when the recording reservation setting for the next broadcast is forgotten, it is determined that the setting has been forgotten, and automatic recording can be set reliably. The purpose is to provide a device.

  Furthermore, the present invention not only automatically extracts recommended recording programs, but can also automatically extract the extracted programs up to the recording reservation setting, and in addition, the recording reservation is made for the program that meets the user's preference. Another object of the present invention is to provide an automatic recording device that can do this.

  The automatic recording apparatus according to the subject of the present invention includes recording reservation storage setting means for setting recording and storing recording reservation information which is information of a currently reserved program, and information of each program recorded in the past. From recording history storage means for storing recording history, program information supply means for supplying program information of a program scheduled to be broadcast from now on, recording history output from the recording history storage means, and recording reservation storage setting means Comparing with the recording reservation information to be output, a program that is in the recording history but not in the recording reservation information is detected, and a program corresponding to the detected program is output from the program information supply means. If there is in the program information, the first scheduled recording program extracting means for extracting the program as a scheduled recording program, and the user's operation information for each program recorded in the past. The operation history storage means for storing the recording history, the recording history output from the recording history storage means and the operation history output from the operation history storage means are acquired and included in the recording history based on the operation history After determining the weighting, which is the degree that matches the user's preference for each program, the recorded program information that combines the recording history, the operation history, and the weighting is determined, and based on the recorded program information Recorded program information determination means for calculating a recommended recording value reflecting the weight for each item in the recording history, the program information output from the program information supply means, and the item output from the recorded program information determination means The recommended recording value for each item is obtained, and for each program scheduled to be broadcast included in the program information, the sum of recommended recording values for each item is calculated. A total recommended recording value representing the recommended degree of the program, and a broadcast scheduled program whose total recommended recording value is equal to or greater than a predetermined reference value is extracted as a scheduled recording program from the program information. A recording reservation program extracting means, wherein the recording reservation storage setting means adds the information of the recording reservation program extracted by the first recording reservation program extraction means and the second recording reservation program extraction means to the recording reservation information. Thus, the recording setting of the scheduled recording program is performed.

  Hereinafter, various embodiments of the subject of the present invention will be described in detail along with the effects and advantages thereof with reference to the accompanying drawings.

  According to the subject matter of the present invention, even when the recording reservation for the next broadcast is forgotten, it can be determined that the setting has been forgotten and the recording reservation can be reliably set.

  Furthermore, according to the subject of the present invention, not only the recommended recording program can be automatically extracted, but the extracted program can be automatically set up to the recording reservation setting, and further, the program suitable for the user's preference. Can be reserved for recording.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of an automatic recording apparatus according to the present embodiment. In FIG. 1, a recording history storage unit 101 stores a recording history of programs recorded in the past. The recording reservation storage setting unit 102 stores information on programs reserved for recording, and sets recording reservation when a new reservation is made. The program information supply unit 103 supplies program information of a program scheduled to be broadcast from now on. The first scheduled recording program extraction unit 104 compares the recording history stored in the recording history storage unit 101 with the recording reservation information stored in the recording reservation storage setting unit 102, and finds the recording reservation information in the recording history. In the program information acquired from the program information supply unit 103, the program is extracted. The operation history storage unit 105 stores a user's operation history. The recorded program information extraction unit 106 extracts program information of programs recorded in the past from the recording history stored in the recording history storage unit 101 and the operation history stored in the operation history storage unit 105. The second scheduled recording program extraction unit 107 extracts a program to be scheduled for recording based on the program information acquired from the program information supply unit 103 and the recorded program information acquired from the recorded program information extraction unit 106.

  FIG. 2 is a flowchart showing a basic processing flow in the automatic recording apparatus of FIG. Hereinafter, a basic processing flow will be described with reference to FIG.

  First, the first scheduled recording program extracting unit 104 acquires a recording history of a program recorded in the past from the recording history storage unit 101, and further, information on the currently reserved program from the recording reservation storage setting unit 102. The recording reservation information is acquired (STEP 201).

  An example of the recording history is shown in FIG. As shown in FIG. 3, the recording history is composed of information on a program channel recorded in the past, date, day, start time, end time, program name, genre, and performer. For example, 301 shows one recording history, the channel is 1 channel, the date is October 1, 2006, the day of the week is Sunday, the start time is 19:00, the end time is 19:30, This shows that a program having the program name “Program A”, the genre “Drama”, and the performer “Performer a” has been recorded in the past. That is, FIG. 3 shows that 17 programs from 301 to 317 are stored as the recording history.

  An example of recording reservation information is shown in FIG. As shown in FIG. 4, the recording reservation information is composed of information of a currently reserved program channel, year / month / day, day of the week, start time, end time, and program name. For example, 401 indicates one recording reservation, the channel is 4 channels, the date is October 24, 2006, the day of the week is Wednesday, the start time is 22:00, the end time is 22:30, It shows that a recording reservation with the program name “program D” is set. That is, FIG. 4 shows that eight recording reservations 401 to 408 are set.

  Next, the first scheduled recording program extracting unit 104 compares the acquired recording history with the recording reservation information, and determines whether there is a program that is in the recording history but not in the recording reservation information ( (STEP 202). For example, the first scheduled recording program extracting unit 104 compares the recording history in FIG. 3 with the recording reservation information in FIG. First, the part 104 determines whether or not there is a program corresponding to the program in the recording history 301 in FIG. At that time, the same section 104 determines whether there is a program A having the same program name on the same channel. Since the recording reservation 407 in FIG. 4 indicates that the program A has the same program name and the same channel, the same section 104 includes a program corresponding to the program in the recording history 301 in the recording reservation information in FIG. If it exists, it can be judged. In making such a determination, the method is not limited to the above-described method. Even if the program names do not completely match, a condition for determining that the program is the same may be added if, for example, the program name character string is the same for five or more consecutive characters. This is because a part of the program name may be omitted or a word may be added as a subtitle. In order to distinguish from programs that are broadcast with the same program name at different times, for example, when determining that the start times are the same or that the start time difference is within ± 3 hours It may be added as a condition.

  When judging from 302 to 317 in FIG. 3 by the same method, the first scheduled recording program extracting unit 104 reads the program C recorded from 13:00 on 2006/10/2 of 303 and 2006/10 on 305. 4 is detected in the recording history, but there is no recording reservation that can be regarded as the same program in FIG. If all the programs in the recording history of FIG. 3 are present in the recording reservation of FIG. 4, the first recording reserved program extraction unit 104 proceeds to the processing of STEP 206.

  Next, the first scheduled recording program extraction unit 104 acquires program information of a program scheduled to be broadcast from the program information supply unit 103 (STEP 203). Such program information is generally called EPG (Electronic Program Guide), which is superimposed on a broadcast wave or published on the Internet, and receives the broadcast wave or connects to the Internet. Thus, it is possible to obtain an EPG.

  In addition, if there is a program that is in the recording history and is not included in the recording reservation information, the first recording reserved program extracting unit 104 acquires the program information that the program corresponding to the extracted program is acquired from the program information supply unit 103. Is checked (STEP 204). In the above example of FIGS. 3 and 4, since the program C of 303 and the program E of 305 in FIG. 3 correspond to programs that are in the recording history but not in the recording reservation information, the first recording reserved program is extracted. The unit 104 checks whether a program corresponding to each of the program C and the program E exists in the acquired program information.

  As a method of checking whether or not the program information includes the program C and the program E, it can be determined by a method similar to the method described in STEP202. That is, a program with the same channel and the same program name is searched. Depending on the case, the search can be performed under conditions such as the close program name, the start time being the same, or the close time.

  When a corresponding program is found in the program information, the first scheduled recording program extracting unit 104 determines that the extracted program is a program that should be reserved but forgotten to be reserved. The program is reserved (STEP 205). As a result of the examination, if it is assumed that there is a program C in the program information at 13:00 on 2006/10/23 and a program E at 18:00 on 2006/10/25, as shown in FIG. The first scheduled recording program extraction unit 104 reserves recording of the program C and the program E of 510, and the recording reservation storage setting unit 102 records the program C and the program E of 510 that are newly reserved for recording. Add to booking information.

  By performing the above processing, it is possible to prevent forgetting to record the next broadcast of a program recorded in the past.

  After the recording reservation storage setting unit 102 sets the recording reservation in STEP 205, or when there is no corresponding program in STEP 204, the automatic recording apparatus advances the processing to STEP 206.

  Next, the recorded program information determination unit 106 acquires a recording history from the recording history storage unit 101 and also acquires an operation history corresponding to the recording history from the operation history storage unit 105, and weights described later from the operation history. decide. Then, the recorded program information determination unit 106 adds the determined weight to the recording history and the operation history, and determines the recorded program information of the previously recorded program determined from the recording history (STEP 206). An example of such recorded program information is shown in FIG. The recorded program information in FIG. 6 is data that summarizes the recording history, the operation history of each program, and the weight determined from the operation history. In this example, the operation history includes the number of days elapsed since the recording date, the presence / absence of dubbing of the recorded program, and the playback rate for the entire time of the recorded program. That is, the operation history storage unit 105 measures the number of days that have elapsed from the recording date of the recorded program for each order of the recorded program indicated in the recording history, and dubbing the recorded program on a removable recording medium described later. It is determined whether or not the recorded program has been played, and the ratio of the recorded program played back with respect to the time length of the recorded program (reproduction rate) is measured, whereby each measurement result and determination result (presence / absence) are recorded. The number of days elapsed since the day, the presence / absence of dubbing of the recorded program, and the playback rate for the entire time of the recorded program are stored.

  Here, a method in which the recorded program information determination unit 106 determines the weight of each recorded program from the acquired operation history data will be described based on the flowchart shown in FIG. The weighting is determined for each recorded program.

  First, the recorded program information determination unit 106 checks from the operation history whether or not a certain period has elapsed after the recording of the recorded program has ended (STEP 701).

  If the recorded program is reproduced from the beginning to the end, it can be determined that the user has watched the program with interest. However, just because a program is not played back immediately after recording cannot be determined that the program does not meet the user's preference. Therefore, it is necessary to determine whether or not the recorded program has been reproduced after a certain period of time has elapsed since recording. Therefore, if the predetermined period has not elapsed, the recorded program information determination unit 106 determines that the weight for the recorded program is 1 (STEP 702) in the sense that the program is not a determination target program.

  If a certain period of time has elapsed after recording, the recorded program information determination unit 106 regards the recorded program as a determination target program. Next, the recorded program information determination unit 106 checks whether or not the corresponding recorded program has been dubbed to “removable media” from the operation history (STEP 703). Here, “removable medium” means a medium on which a recording medium such as a DVD or VTR video tape can be taken out from the recording apparatus and stored. If the recorded program is dubbed to removable media, the fact means the user's intention to save the program, regardless of whether it was played or not played. Therefore, it can be determined that the corresponding recorded program is a program that matches the user's preference. Therefore, when the corresponding recorded program is dubbed, the recorded program information determination unit 106 determines that the corresponding recorded program is a program that matches the user's preference, and determines the weight as 1 (STEP 704). ).

  If the recorded program has not been dubbed, the recorded program information determination unit 106 next sets the recording time of the recorded program as 100%, and “reproduce” "Rate" is checked from the operation history. First, the recorded program information determination unit 106 checks whether or not the playback rate of the corresponding recorded program is 20% or less of the recording time (STEP 705). If the playback rate is 20% or less, the recorded program information determination unit 106 determines that the corresponding recorded program is far from the user's preference, and determines the weight to be 0.25 (STEP 706). On the other hand, if the playback rate exceeds 20%, the recorded program information determination unit 106 next checks whether or not the playback rate of the corresponding recorded program is 50% or less of the total recording time (STEP 707). ). If the playback rate is 50% or less, the recorded program information determining unit 106 determines that the corresponding recorded program is slightly away from the user's preference, and determines the weighting as 0.5 (STEP 708). . On the other hand, if the playback rate exceeds 50%, the recorded program information determination unit 106 determines that the corresponding recorded program is a program that matches the user's preference, and determines the weight to be 1 (STEP 709). ). By the above-described method, the recorded program information determination unit 106 sequentially determines the weighting of each subsequent recorded program from the operation history.

  A specific example of the recorded program information created by the recorded program information determination unit 106 is shown in FIG. In FIG. 6, it is assumed that the current time is 2006/10/23. In addition, the fixed period after recording is 7 days, and when 7 days have not elapsed, it is determined that the program does not match the preference and the weight is set to 1. Here, the fixed period after recording is 7 days, but it is not limited to 7 days. In FIG. 6, in the case of the program A 617 of 2006/10/22 starting at 19:00, the elapsed time is 1 day and 7 days have not passed, so the weight is 1. In the case of the program E starting at 18:00 on 2006/10/4 of 605 in FIG. 6, the elapsed time is 19 days, 7 days or more have passed, and dubbing is present, so the playback rate is 0. Even so, the weight is 1. In the case of the program B starting at 20:00 on 2006/10/8 in 610 in FIG. 6, the number of days elapsed is 7 days or more and there is no dubbing. Determine the playback rate. In this case, since the reproduction rate is 19% and 20% or less, the recorded program information determination unit 106 determines the weight of the recorded program B to be 0.25. In the case of the program G starting at 20:00 on 2006/10/4 of 607 in FIG. 6, the elapsed days are 7 days or more, there is no dubbing, the playback rate is 37% and exceeds 20%. However, since it is 50% or less, the recorded program information determination unit 106 determines the weight of the recorded program G to be 0.5. For the remaining programs, all the elapsed days are 7 days or more, no dubbing is performed, and the playback rate exceeds 50%. Therefore, the recorded program information determination unit 106 sets the weight of all remaining recorded programs to 1 decide.

  The above processing is the flow of weight determination. As described above, the weighting for each recorded program is determined based on the operation history, and the recorded program information as shown in FIG. 6 is created by adding the weight of each recorded program to the recording history information. Even if the program does not meet the user's preference, the accuracy of extracting the next recommended recording program can be prevented from being lowered.

  After determining the weight of each recorded program, the recorded program information determination unit 106 creates or determines the recorded program information by adding the weight obtained from the operation history to the recorded history, as described above. Based on the recorded program information, each recommended recording value is calculated for each item in the recording history in the recorded program information (STEP 206). A method for calculating each recommended recording value for each item will be described below by taking a channel as an example of “item”. For this purpose, an operation for calculating the recommended recording value for each channel will be described with reference to an example of FIGS.

  First, the recorded program information determination unit 106 obtains the number of times of recording for each channel from the recorded program information shown in FIG. For example, since the channel 1 is recorded four times, the recorded program information determination unit 106 determines the number of times of recording for the channel 1 as four times, and similarly determines the number of times of recording for the channel 3 as three times. Here, the recorded program information determination unit 106 checks not the simple number of times of recording, but “weighted number of times of recording” for each channel. The “weighting” here corresponds to the weighting determined according to the flowchart of FIG. For example, from the recorded program information shown in FIG. 6, it is determined that the number of times of recording on channel 2 is three. However, for program B of the recorded program 610, the weight is 0 from the recorded program information shown in FIG. .25. Therefore, the recorded program information determination unit 106 calculates the sum of weights 1 + 0.25 + 1 = 2.25 of the recorded program images 602, 610, and 615 in which the program of channel 2 is recorded, and the calculation result 2.25 is calculated as channel 2 To “weighted recording count”. Similarly, the results obtained for all the other channels are shown in the column of “weighted recording count” in FIG.

  Next, the recorded program information determination unit 106 assigns the points h shown in FIG. 9 to each channel in the order of the channels with the largest “weighted recording count” (see FIG. 8). Then, the recorded program information determination unit 106 calculates the recommended recording value h × w of each channel by multiplying the point h of each channel by “weighting w” representing the importance for each item. Here, the weight w is an arbitrary value satisfying 0 ≦ w ≦ 1. The recorded program information determination unit 106 performs the same operation not only on the channel but also on other items in the recorded program information. 10 shows recommended recording values for each start time (item) calculated for the item “start time”, FIG. 11 shows recommended recording values for each genre (item) calculated for the item “genre”, and FIG. FIG. 13 shows the recommended recording value for each performer (item) calculated for the item “performer”. FIG. 13 shows the recommended recording value for each program name (item) calculated for “name”.

  Here, the weight w used in FIGS. 8, 10, 11, 12, and 13 represents how much importance is given to the judgment of the user's preference among the items. Yes. For example, regarding the channel that is the item shown in FIG. 8 and the start time that is the item shown in FIG. 10, it is considered that the degree of importance in determining the user's preference and determining the recommended recording program is not so great, A relatively low weighting is employed, such as w = 0.3 for the channel and w = 0.4 for the start time. On the other hand, regarding the genre, which is the item shown in FIG. 11, the program name, which is the item shown in FIG. 12, and the performer shown in FIG. A relatively large weighting is employed, such as w = 0.8 for a genre, w = 0.8 for a program name, and w = 0.9 for a performer.

  Next, the second scheduled recording program extraction unit 107 (1) acquired from the program information supply unit 103 and program information of a program scheduled to be broadcast in the future, and (2) acquired from the recorded program information determination unit 106. From the data of recommended recording values (see FIGS. 8, 10, 11, 12, and 13) of each item in the recorded program information (see FIG. 6), a program scheduled to be broadcast (broadcast scheduled program) "Recommended value for total recording" representing the recommended degree is calculated for each program in the program information (to be broadcast in the future) (STEP 207).

  FIG. 14 shows an example of “program information” provided by the program information supply unit 103. FIG. 14 shows some programs among many programs as examples of programs scheduled to be broadcast from now on. Hereinafter, the operation in which the second scheduled recording program extraction unit 107 calculates the “total recommended value” for each program in the program information will be described with reference to FIG.

  First, for each program name in the acquired program information, the second scheduled recording program extraction unit 107 calculates a recommended recording value for each item in the recorded program information from the data shown in FIGS. 8 and 9 to 13 calculated earlier. Check out. For example, in the case of the broadcast-scheduled program B indicated by reference numeral 1401 in FIG. 14, the channel is 2, so that the second scheduled recording program extracting unit 107 recommends recording calculated from channel 2 from the reference numeral 803 in FIG. It is determined that the value is 1.8. 14, the start time of the scheduled program B is 12:00, but in FIG. 10, since 12:00 is not in the ranking, the second scheduled recording program extracting unit 107 is scheduled to broadcast. For program B, the recommended recording value calculated from the start time is determined to be zero. Since the program name is program B, the recommended recording value calculated from the program name for the broadcast scheduled program B by the second scheduled recording program extraction unit 107 is 4.8 from reference numeral 1203 in FIG. And decide. Further, since the genre of the broadcast scheduled program B is animation, the second scheduled recording program extracting unit 107 determines that the recommended recording value calculated from the genre is 5.6 based on reference numeral 1102 in FIG. . Further, since the performer of the broadcast scheduled program B is the performer b, the recommended recording value calculated by the performer is 6.3 from the reference numeral 1302 in FIG. Decide that. Then, the second scheduled recording program extraction unit 107 calculates the total recommended recording value of the broadcast scheduled program B to be 18.5 by adding the recommended recording values of the respective items obtained above. Similarly, when the second scheduled recording program extraction unit 107 obtains the total recommended recording value for each of the other broadcast-scheduled programs in FIG. 14, the calculated result is as shown in FIG.

  Next, the second scheduled recording program extraction unit 107 compares whether or not the total recording recommended value of each broadcast scheduled program is greater than or equal to the reference value, and the total recommended recording value of a certain broadcast scheduled program is the reference value. If it is above, recording reservation is performed with respect to the recording reservation memory | storage setting part 102 so that the applicable broadcast plan program may be recorded (STEP208). In the case of FIG. 15, if the standard value of the recommended total recording value is defined as 12, the second scheduled recording program extracting unit 107 refers to the scheduled broadcast program B indicated by reference numeral 1501 and the scheduled broadcast program C indicated by reference numeral 1505. It is determined that the broadcast-scheduled program K denoted by reference numeral 1506 is a program to be reserved for recording whose recommended total recording value is equal to or greater than a reference value. Therefore, as shown in FIG. 16, the second scheduled recording program extracting unit 107 reserves recording reservation for the scheduled broadcast program B indicated by reference numeral 1601, the scheduled broadcast program C indicated by reference numeral 1602, and the scheduled broadcast program K indicated by reference numeral 1603. The recording reservation storage setting unit 102 additionally sets the recording reservation information shown in FIG. 16 to the already set recording reservation information and stores it.

  In the present embodiment, the dubbing operation and the reproduction operation are used as the user operation history, but the present invention is not limited to these. With a recorder without a dubbing function, the same effect can be obtained even when only the playback operation is measured. In addition, there are recorders that have a program protection function to prevent accidental deletion of programs, but it is possible to determine that a program that has been protected is a program that suits the user's preference. It is also possible to use whether or not the operation has been performed as an operation history.

  By performing the above processing, even if you forget to set the recording reservation for the next broadcast schedule of a program that was recorded in the past, it is determined that you have forgotten the setting, and the recording reservation for that broadcast schedule program is set reliably. Furthermore, it is possible to automatically make a recording reservation for a program that meets the user's preference from the recording history and the user's operation history for the recorded program.
