Description

  The present invention relates to a recommended program extracting apparatus that extracts a recommended program (for example, a recommended recording program or a recommended viewing program) from programs scheduled to be broadcast.

  As a broadcast program recording device, program information is read from the recording history of a program recorded in the past, a program having the same information as the read program information is searched from the broadcast schedule information, and based on this search result There is one that performs scheduled recording (see, for example, Patent Document 1). As another recording apparatus, there is one that grasps a user's preference from a user's operation history, searches for a program that matches the user's preference, and performs scheduled recording based on the search result (see, for example, Patent Document 2). ). As another recording apparatus, there is a recording apparatus that designates a condition of a program that the user wants to make a recording reservation in advance, periodically searches broadcast schedule information, and automatically records a program that meets the condition (for example, Patent Literature). 3).

JP 2001-257974 A (paragraphs 0029-0031, FIG. 1) JP 2001-84420 A (paragraphs 0056-0057, FIGS. 1 and 12) JP-A-7-121935 (paragraphs 0014-0016, FIG. 1)

  However, the recording apparatus disclosed in Patent Document 1 can only make a recording reservation for a broadcast program in which the program information of the program recorded in the past and the program information “match”, and the user's preference is the program information of the program recorded in the past. Therefore, there is a problem in that it is not possible to appropriately extract a program that matches the user's preference and make a recording reservation.

  The recording apparatus disclosed in Patent Document 2 gives positive or negative points according to each operation such as program selection, viewing, recording, recording reservation, and deletion of recorded programs by the user (that is, the operation is scored). Since the degree of preference is determined by this, it is necessary to perform information processing for various operations by the user, and there is a problem that a large memory area is required to store a program for complicated information processing. . Further, in Patent Document 2, as to how to extract a program to be recorded from the scored preference degree, “a plurality of patterns are conceivable as to what is automatically continued and automatic recording is performed. Series, the same genre, the same performer, the same writer, the director, etc. (paragraph 0057) ”, and no specific automatic recording algorithm is shown. .

  Moreover, in the recording apparatus disclosed in Patent Document 3, it is necessary for the user to input information such as the program type or the performer in advance as the recording condition, and when the condition of the program desired to be recorded changes, each time, There is a problem that the user needs to change the recording condition and input again, which is troublesome.

  Furthermore, in the above-described conventional apparatus, when a plurality of users share one recording apparatus, recommended programs are extracted based on program information recorded by all users. The extracted recommended program information includes information that is almost unnecessary for the user currently using the apparatus, and can be information that confuses the user. In other words, since recommended program information is extracted from program information recorded in the past of all users who share the recording device, the extraction information most needed by the user who currently uses the device is extracted by other users. There is a problem that the extraction function of the recommended program may become a function having no utility value because it may be buried in necessary extraction information.

  The present invention has been made in order to solve the conventional problems as described above, and provides a recommended program extracting apparatus capable of extracting recommended programs for each user from programs scheduled to be broadcast. Objective.

As a result of counting the number of times of recording corresponding to various conditions such as program type and program name for all programs recorded by the user within the preset recorded program information extraction period or until reaching the preset number of times of recording. It is generated based on.

  FIG. 6 is a diagram for explaining recommended program extraction processing by the recommended program extracting unit 54 of the recommended program extracting apparatus according to the first embodiment. FIG. 7 is a diagram showing an example of a correspondence table between the ranking of the number of recording times and the points used by the recommended program extracting unit 54 of the recommended program extracting apparatus according to the first embodiment. 8 and 9 are diagrams for explaining an example of how to obtain the total recommended value by the recommended program extracting unit 54 of the recommended program extracting apparatus according to the first embodiment.

  The recommended setting list 75 shown in FIG. 6 includes the number of recordings by condition (column 76 in the list 75), the point “h” (column 77 in the list 75), and the recommended value “h × w” (column 78 in the list 75). ). The number of times of recording by condition (column 76 of list 75) is the number of times based on the type list 70 in the recorded program information extraction list 69 shown in FIG. The point “h” (column 77 in the list 75) shown in FIG. 6 is a point given based on the correspondence table in FIG. As shown in FIG. 7, in the first embodiment, when the ranking of the number of times of recording (for example, type, program name, start time, channel, performer) is first, 7 points, second place The points are changed by 1 point for each rank, such as 6 points in the case of 5 and 5 points in the case of the third place. However, two or more points may be changed for each rank, and points may be arbitrarily set for each rank. The recommended value “h × w” (column 78 of the list 75) shown in FIG. 6 indicates the type of program (list 70 in FIG. 5) in order to determine the priority for setting the recommended program at the point “h”. ), Program name (list 71 in FIG. 5), start time (list 72 in FIG. 5), channel (list 73 in FIG. 5), performer (list 74 in FIG. Weighting coefficient) is a value obtained by multiplying “w”. The weighting coefficient “w” of each item is an arbitrary value satisfying 0 ≦ w ≦ 1. FIG. 6 shows a case where the weighting coefficient “w” is set to 0.8 for each item, but the weighting coefficient may be different for each item.

  The weighting coefficient “w” is set for each item “type”, “program name”, “start time”, “channel”, and “performer” shown in the recorded program information extraction list 69 of FIG. Are preset. The weighting coefficient “w” focuses on any of the items “type”, “program name”, “start time”, “channel”, and “performer” shown in the recorded program information extraction list 69 of FIG. Is a coefficient for deciding whether to extract recommended programs. For example, when a recommended program is extracted with the most emphasis on “performers”, the weighting coefficient “w” of “performers” is set to a larger value (a value closer to 1) than other items. For example, when “start time” and “channel” are not important items, the weighting coefficient “w” of “start time” and “channel” is set to a relatively small value (a value close to 0). .

  As described above, statistical processing is performed for each type of program recorded in the past, and the recommended setting list 75 shown in FIG. 6 is created. Next, using the statistical processing result, an overall recommended value is calculated for the program scheduled to be broadcast. For example, as shown in FIGS. 8 and 9, the program information scheduled to be broadcast is acquired from the broadcast program attribute information supply means 51, and the point “h” (table of FIG. And the recommended value “h × w” (row 81 in the table of FIG. 8) is obtained using the weighting coefficient “w” (row 80 of the table of FIG. 8), and the recommended value “h × w” is determined. And the total value is calculated as a comprehensive recommended value (column 82 in FIG. 8). FIG. 8 shows an example of calculating the total recommended value for the program “EEE” in the program information supply list 56 shown in FIG. 3, and FIG. 9 shows the total recommended value for the program “FFF” in the program information supply list 56 shown in FIG. An example of the calculation is shown.

  FIG. 10 is a diagram for explaining the operation of the extraction result display means 55 of the recommended program extracting apparatus according to the first embodiment. In the recommended program extracting unit 54, a total recommended value is calculated for each program, a program whose total recommended value is equal to or larger than a preset value is extracted, and the result is listed and displayed by the extraction result display unit 55. To do. For example, the recommended program extraction list 87 shown in FIG. 10 is displayed. The recommended program extraction list 87 includes a date (column 88 of the list 87), a program name (column 89 of the list 87), a start time (column 90 of the list 87), an end time (column 91 of the list 87), It consists of items of channels (column 92 in list 87).

  Next, the recommended program extraction operation by the recommended program extraction apparatus according to the first embodiment will be described. First, the user specifying means 93 shown in FIG. 2 specifies (identifies) a user based on the input user number. Next, the recorded program / user specifying information storage means 52 stores a recording history of programs that have been recorded in the past for the specified user. An example of the recording history is a recording information list 64 shown in FIG. 4, and this list 64 includes information on the date, recording start time, recording end time, and recording channel when the user performed recording. . For example, when the user sets the reserved recording, it is necessary to set the broadcast date, recording start time, recording end time, recording channel, and user specific information of the program to be recorded. Is stored in a non-volatile memory (reference numeral 19 in FIG. 1) provided in the recommended program extracting apparatus, it is possible to store a recording history. In addition, if the user starts the recording by pressing the recording button of the recommended program extraction device instead of the reserved recording and performs the recording operation such as stopping the recording by pressing the stop button, the recommended program The clock (not shown) built in the extraction device can know the date and time of recording, the recording start time and the end time, and can also know the recorded channel from the tuner tuning status at this time. it can. Therefore, even when such a recording is performed, the recording date, the time when recording was started, the time when recording was completed, and the recorded channel information are retained in the nonvolatile memory, so that a history recorded in the past can be obtained. It is possible to memorize it.

  Next, the recorded program attribute information extracting means 53 is a figure detected by the program attribute information supply list 56 shown in FIG. 3 supplied by the broadcast program attribute information supplying means 51 and the recorded program / user specifying information storage means 52. 4 is collated, and it is determined which of the program information supplied by the broadcast program attribute information supply means 51 is what the user has recorded in the past. Comparing the program attribute information supply list 56 shown in FIG. 3 with the recorded information list 64 shown in FIG. 4, the recorded program associated with the user “1” is recorded from 21:00 to 22:00 on February 15, 2003. Drama “Program name: AAA” of the channel “8” and the news “Program name: BBB” of the channel “8” recorded from 22:00 to 22:30 on February 15, 2003, 2003 The music “program name: CCC” recorded on the channel “4” recorded from 18:30 to 19:00 on February 17 and the channel “19” recorded from 20:00 to 20:30 on March 5, 2003. It is understood that the program is “program name: FFF”.

  FIG. 4 shows a case where the start / end times of the program information supply list 56 and the start / end times of the recording information list 64 match, but the start / end times do not necessarily match. When the start / end times of the program information supply list 56 and the start / end times of the recording information list 64 do not match, only a part of the programs in the program information supply list 56 is recorded, There is a case where the program is recorded at once. When only a part of a program is recorded, for example, when 50% or more of the broadcast time of the program is recorded, it is regarded as a corresponding program, and less than 50% of the broadcast time is recorded. If it is, it is judged that the program is not regarded as a corresponding program. Further, when a plurality of programs broadcast continuously are recorded continuously, a determination is made such that each of the plurality of programs is regarded as a corresponding program.

  Next, program attribute information is extracted from the program information supply list 56 for the recorded program, and a recorded program information extraction list 69 shown in FIG. 5 is generated. The recorded program information extraction list 69 includes a predetermined period (for example, the latest one month) or a predetermined number of recordings according to the conditions of the type, program name, program start time, channel, performer, etc. It is generated based on the result of counting the number of times of recording according to the condition of how many times the recording corresponding to each condition has been performed until reaching (for example, the latest 100 times). In the recorded program information extraction list 69, the start time 72 is counted as starting at 20:00:00 if the recording start time is from 20:00 to 20:59:59. . For example, for the program shown in FIG. 3 (program name “BBB”), the count is added to the news as the type, the count is added to the program name “BBB” as the program name, and the start time is 22:00. 1 is added to the minute, 1 is added to the channel “8”, and 1 is added to the performer “bb” as the performer. Such processing is executed for all programs recorded within a preset period or until a preset number of recordings is reached. In the above description, the case where the program start time is handled in units of one hour has been described. However, for example, the program start time may be handled in smaller units such as 10 minutes, 15 minutes, and 30 minutes. You may make it handle by a coarser unit like 2 hours, 3 hours, and a half day unit.

  Next, as shown in FIG. 6, the recommended program extracting unit 54 extracts the number of recordings by condition for the recorded program attribute information extraction list 69 shown in FIG. 5 generated by the recorded program attribute information extracting unit 53. Statistical processing is performed on 76, and a recommended program to be recorded for the broadcasted program is extracted.

  First, paying attention to the program type 70, the point “h” (column 77 in the list 75 in FIG. 6) is obtained for the number of recordings 76 by condition. The point “h” is determined based on the order of the number of times of recording as shown in FIG. 7, for example. For example, in the case of news, the value of the point “h” is 7 because the number of times of recording is first in the example shown in FIG. Thereby, a high point is given to the type recorded many times in the past. In FIG. 6, only the type 70 is shown, but the respective points are similarly obtained for the conditions of program name, start time, channel, and performer. Also for these other conditions, as shown in FIG. 7, each point “h” is determined by the order of the number of times of recording.

  Next, a recommended value “h × w” (column 78 in the list 75) that is a value obtained by multiplying the weighting coefficient “w” for determining the priority when setting the recording recommendation by the point “h” is obtained. . However, 0 ≦ w ≦ 1. In FIG. 6, the recommended recording setting list 75 for the condition of the type including items such as news, drama, movie, music, animation, variety, and education is shown as an example, but the program name, start time, channel, appearance Similarly, a recommended value is obtained for the condition of the person etc., and a recommended setting list 75 is generated. These are statistical processes for determining how important each item is to be reflected in the extraction of recommended programs. In the example shown in FIG. 6, it is determined that the program type is a relatively important condition, and a relatively large value is set to w = 0.8. For example, since it is a very important condition for performers, it is considered better to have a strongly recommended value. For example, a large value such as w = 0.9 is set, and the channel is not so important. In consideration, for example, a small value such as w = 0.3 is set.

  Further, the recommended program extracting unit 54 obtains a comprehensive recommended value described below for the broadcast program based on the recommended setting list 75 obtained by the above method. If the total recommended value is large, it is determined that the program is highly recommended for recording.

  In the program attribute information supply list 56 shown in FIG. 3 which is the program information supplied by the broadcast program attribute information supply means 51, the program “EEE” and the program “FFF” scheduled to be broadcast are taken as examples of the total recommended value. Explain how to find it. Here, as a value of the predetermined weight “w”, the type is “0.8”, the program name is “0.8”, the start time is “0.4”, and the channel is “0.3”. For performers, “0.9” is set. Note that the value of the weighting coefficient “w” may be a value other than the above as long as 0 ≦ w ≦ 1. Furthermore, the value of “w” for the type, program name, and performer in which the value of the weighting coefficient “w” is set large is set small, and the value of the start time and the channel weight “w” is set to a large value. Also good. Further, the weighting coefficient “w” may be configured to be changeable by the user.

  As shown in FIG. 8, the program “EEE” has the type “news”, the program name “EEE”, the start time “19:00”, the channel “6”, and the performer “ee”. The recommended value can be obtained by the above-described processing described with reference to FIGS. The recommended value of the program “EEE” is “5.6” for the type “news”, “3.2” for the program name “EEE”, “2.0” for the start time “19:00”, channel “1.5” for “6” and “0” for performer “ee”. The total value of these recommended values is the total recommended value. Therefore, the total recommended value of the program “EEE” is “12.3” as shown in FIG. Similarly, the total recommended value of the program “FFF” is “5.5” as shown in FIG.

  The determination as to whether or not the program is recommended for recording (or viewing) is made based on the size of the total recommended value calculated as described above. For example, when the reference value for making this determination is set to “10.0”, the calculated comprehensive recommended value is compared with this reference value, and the program “EEE” having the comprehensive recommended value that is equal to or greater than the reference value is the recommended program. The program “FFF” having a comprehensive recommended value less than the reference value is not a recommended program. In this way, a total recommended value is obtained for a program scheduled to be broadcast, and a recommended program is determined by extracting a program in which the recommended value is equal to or greater than the reference value by the recommended program extracting means 54.

  The program extracted by the above method is displayed by the extraction result display means 55. For example, programs extracted as a list 87 as shown in FIG. 10 are displayed.
