Description

  The present invention relates to a television broadcast receiving apparatus that receives and records a television broadcast, and in particular, learns a user's viewing tendency from past operation histories (program viewing, recording, playback, etc.), and a television program based on that information. The present invention relates to a technique for automatically recording video.

  Conventionally, when a television program is recorded with a VTR, a DVD recorder, a hard disk recorder, or the like, the user has to perform a recording or recording reservation operation.

In order to simplify the recording or recording reservation operation, automatic recording based on the user's viewing history has been proposed (see, for example, Patent Document 1).
JP-A-5-62283

  By the way, there are many ways to see a general television program, and the same program is viewed at almost the same time, and there are surprisingly few programs that are consciously thinking about watching the program. In the conventional method, programs with high viewing frequency are preferentially recorded, and the above-mentioned programs also become garbage when automatically recorded due to high viewing frequency. There is a problem that a certain program is not recorded because the viewing frequency is low.

  The present invention has been made in view of the above points, and by calculating the degree of preference based on the user's original preference regardless of the time zone viewing frequency, the degree of reflection of the user's preference in the automatic recording process An object of the present invention is to provide a television broadcast receiving apparatus having an improved level.

In order to solve the above-mentioned problems, the present invention comprises the following means 1) to 2).
That is,
1) a channel selection means for a user to select a desired program from a digital broadcast television signal;
Time information detecting means for detecting time information of the selected program;
Genre information acquisition means for acquiring genre information of the selected program;
Storage means for storing the detected time information and the acquired genre information;
Viewing tendency information generating means for extracting time information and genre information of the user-selected program in a predetermined past period from the contents of the storage means, and generating user viewing tendency information;
Have
A television broadcast receiving apparatus, wherein a program desired by a user is automatically recorded based on the viewing tendency information of the user generated by the viewing tendency information generating means.

  2) When the viewing tendency information generating means switches from the state of continuously watching the same program to another program regarding the past specific time information in the contents of the storage means, the viewing tendency of the different program is viewed. The television broadcast receiver according to 1), wherein the tendency priority is increased.

  According to the “television broadcast receiving apparatus” of the present invention, it is possible to calculate a preference degree based on the user's original preference regardless of the viewing frequency, and the reflection degree of the user's preference is increased in the automatic recording process. A television broadcast receiver can be provided.

  Also, it is possible to provide a television broadcast receiving apparatus that can be made closer to the user's original preference by obtaining preference information not only from the preference information in the recorded program but also from the TV program being viewed. Can do.

  The best mode for carrying out the invention of the television broadcast receiving apparatus according to the present invention will be described below with reference to preferred embodiments.

  FIG. 1 is a schematic block diagram showing the configuration of a television broadcast receiving apparatus applied to this embodiment. As shown in the figure, the television broadcast receiving device 12 includes a tuner unit 1, a remote control signal reception processing unit 6, an EPG acquisition processing unit 5, an operation history creation processing unit 7, a storage device 8, and an inter-program priority information creation processing unit 3. The automatic recording processing unit 4 is configured.

  The television broadcast receiver 12 receives a television broadcast with the antenna 10, selects a channel with the tuner unit 1 and demodulates the video signal, and then uses the demodulated video signal as an EPG acquisition processing unit 5 and an automatic recording processing unit. 4 and the monitor 11. The remote control signal reception processing unit 6 performs a channel selection operation of the remote control 9 by the user and supplies a remote control signal to the operation history creation processing unit 7. The operation history creation processing unit 7 creates an operation history of the device and supplies it to the storage device 8.

  In addition, the EPG acquisition processing unit 5 extracts the received program information and EPG information from the supplied video signal and supplies them to the storage device 8. The storage device 8 for storing these can be accessed randomly, and supplies the stored EPG information and past operation history information to the inter-program priority information creation processing unit 3. The inter-program priority information creation processing unit 3 creates priority information between programs at a specific date and time based on the supplied information. Based on the created information, the automatic recording processing unit 4 performs automatic recording.

  In the inter-program priority information creation processing unit 3, not only the accumulated EPG information and past operation history information but also the reproduction information of the video signal automatically recorded by the automatic recording processing unit 4 is extracted to determine the user's preference. I am doing so.

  The procedure for creating the priority information between programs will be described below with reference to the flowchart of FIG. As shown in the figure, the inter-program priority information creation processing unit 3 first searches the storage device 8 for program information for the corresponding date and time, for example, between 19:00 and 20:00 every Tuesday in the past 10 weeks (step ST1), operation history information in the same period is extracted from the storage device 8 (step ST2).

  FIG. 3 shows a program list created from the operation history information and EPG information. In the figure, the portion indicated by filling is a program determined to have been watching the program from the operation history information. An example of EPG information at this time is shown in FIG. 4, and an example of operation history information is shown in FIG.

  The first record of the operation history shows that the program key is 2, and thus the program with ID 2 in the EPG information has been viewed. Similarly, the second record indicates that the EPG information ID6 program has been viewed.

  Next, in the example for each program, there are four types of programs: news, variety, documentary, and travel. (In this case, it may be considered as a channel.) A parameter for holding the priority between programs assigned to the program is initialized (step ST3). This is repeated for each program (step ST4).

  Next, the degree of similarity of the contents viewed every time for each program is obtained (step ST5). This can be done, for example, by determining the similarity of each program by using a word vector space model or the like after morphological analysis is performed on the program content description sentence of the EPG data of each program to morpheme.

  In the present embodiment, the description of the program content is used as an element for obtaining the similarity, but the similarity may be obtained more finely by adding other elements such as a title, a genre, and a performer.

  Next, the similarity is similarly obtained for the same program that is not viewed based on the obtained similarity, and is classified into those that are similar and those that are not. In FIG. 3, the shaded portion represents a program that has not been viewed that is similar to the view that has been viewed. In the present embodiment, the variety program shows that the contents are similar throughout the target period. On the other hand, for example, the travel program viewed twice is a travel program for overseas travel, and the other is related to domestic travel and the similarity is classified. Further, for example, in a documentary program, one viewing is a documentary related to economic problems, and the other is related to natural science and the degree of similarity is classified.

  After the initialization step, a program (variety) determined to be viewed based on the operation history is selected from the oldest date and time, and it is checked whether there is a program viewed in the past other than the program (variety) (step ST6). ). At this stage (1/21), since there is no more past data, it is determined that there is no past data, and the corresponding program parameter viewed is incremented by one.

  The processing target is moved to the next day (1/28) (step ST9), and the same processing is performed. Also in this case, since there is no program viewed in the past (1/21) other than the program viewed (variety), the parameter of the corresponding program viewed is incremented by one. The same process is repeated until 2/11.

  In the operation history information of 2/18, a travel program is watched, and a variety program that was normally watched is not watched. Furthermore, it is known that the variety programs that have been viewed up to the previous time and the variety programs that have not been viewed this time are similar in content, based on the similarity of each program that has already been obtained. Since this is considered to be conscious of a travel program (overseas travel) different from the variety program that was normally viewed, it is determined in step ST6 that "the program that was normally viewed was not seen", and the program that was viewed As the priority information parameter, a value obtained by adding 1 to the maximum parameter value of the program viewed in the past is set (step ST8). The parameters of each program at this time are news: 0, variety: 4, documentary: 0, travel (overseas travel): 5.

  In the next week, since the variety was watched again, the variety parameter is incremented by +1, and at the same time, the parameter of the program having a higher priority than itself is incremented by one. In this case, since the trip is 5, it is set to 6 (step ST7). The same processing is repeated up to 3/4.

  In the 3/11 investigation history information, a documentary program (economic problem) is being watched, and a variety program that was normally watched is not being watched. Therefore, all the parameters of the program having a higher priority than the corresponding program are incremented by one. (Step ST8). The parameters of each program at this point are: News: 0, Variety: 6, Documentary (Economic Issues): 7, Travel (Overseas Travel): 7, Documentary (Economic Issues) and Travel (Overseas Travel) have the same priority It becomes.

  By repeating the above processing, the final (as of 3/25) parameters of each program are as follows: news: 0, variety: 7, documentary (economic problem): 8, travel (overseas travel): 9.

  From this result, the times with a common similarity such as documentary (economic problem) and travel (overseas travel) are higher in priority than the variety program with the highest viewing frequency, and it depends on the viewing frequency. It can be seen that the preference of the program is determined based on the user's original preference.

  By recording a program having a large value for each time zone based on the inter-program priority information thus obtained, automatic recording based on the user's original preference can be performed.

It is the schematic block diagram which showed the structure of the television broadcast receiver applied to a present Example. It is a flowchart for demonstrating the preparation procedure of the priority information between programs. It is a figure which shows an example of the program list produced from operation history information and EPG information. It is the figure which showed an example of the EPG information in FIG. It is the figure which showed an example of the operation history information in FIG.
