FIG. 1 is a block diagram showing a configuration of a broadcast terminal device according to an embodiment of the present invention. In FIG. 1, 1 is an antenna for receiving a broadcast wave, 2 is a tuner for detecting a broadcast channel from the received broadcast wave and extracting a signal, 3 is a demodulator for demodulating the detected broadcast wave, and 4 is a demodulator. A TS decoder for expanding and decoding an MPEG-2 TS (Transport Stream) signal among the signals, and a decoder 5 for expanding an image / audio signal (that is, for example, an MPEG-2 AV signal) among the demodulated signals. An AV decoder 6 for extracting audio from an AV signal decoded by the AV decoder 5; and an audio decoder 7 for extracting an image (moving image, still image) from the AV signal decoded by the AV decoder 5. An image reproducing unit 8 is a monitor for displaying a reproduced image. Reference numeral 9 denotes a data storage unit for storing various information of a program to be recorded / reproduced, 10 an input unit for inputting various commands by a user operation, and 11 a system control unit for controlling the overall operation of the broadcast terminal device. And a CPU is used.
Further, reference numeral 12 denotes a system bus connected between the above-described functional units and transmitting data and control signals.

The data storage section 9 includes, as data storage means, a video / audio information holding section 21 for storing video and audio data as program contents, and a recorded program information holding section for storing information about recorded programs. 22 and a program information holding unit 23 in which information of a broadcast program such as an EPG is stored.
A history storage unit 24 for storing user operation history in the past, that is, data relating to usage status, a setting information storage unit 25 for storing data relating to various setting contents for the broadcast terminal device, and a degree of importance of the stored data. Operation importance holding unit 26 in which weighting data representing
And a preference information holding unit 27 in which information on the user's preference from the usage status of the user is stored.

The operation of the broadcasting terminal having such a configuration will be described below. FIG. 2 is a flowchart illustrating the operation of the broadcast terminal device according to the present embodiment. In FIG. 2, when the operation of the broadcast terminal device starts, the CPU 11
Checks whether or not a user (user) has input a command in a processing step (hereinafter simply referred to as a step) ST1, and if there is no input, repeatedly checks for input. On the other hand, when a command is input, a process corresponding to the content of the command input in step ST2 is performed. The processing corresponding to the command input refers to processing such as program selection, viewing, recording, recording reservation, deletion of a recorded program, and the like. Next, the CPU 11 determines whether the program to be processed is a currently broadcasted program or a recorded program (step ST11).
3). If the program to be processed is a program that is currently being broadcast, the corresponding program information is acquired from the program information holding unit 23 (step ST4), the process corresponding to the command content is performed, and the operation is performed. The type and the program information are registered in the history holding unit 24 (step ST5). Regarding the processing of step ST4, the program information holding unit 23
, The program information is acquired and held in advance, or the information of the program being broadcast at the same time is acquired and held.
If it is determined in step ST3 that the program to be processed is a recorded program, the corresponding program information is obtained from the recorded program information holding unit 22 (step ST6), and the processing corresponding to the content of the command is performed. And the type of operation and the program information are registered in the history holding unit 24 (step ST5). Regarding the process of step ST6, the recorded program information holding unit 22 holds the program information in association with the recording. As a result, the history information is accumulated in the history holding unit 24 every time a command for operating the broadcast terminal device is input and operated by the user.

FIG. 3 is a diagram showing a storage state of the history information stored in the history holding unit. As shown in this figure, as the history information 30, the operation history of the broadcast terminal device is the date and time 33,
It is stored in various types such as an operation type 34 and program information 35. And, as date and time 33, year, month, day,
Date or time information such as hours, minutes, and seconds is stored as data, and various operations such as viewing, recording, deletion, saving, and leaving are stored as data as the operation type 34. Here, “viewing” in this embodiment means that the user views a program being broadcast for a certain period of time or more by himself / herself, or views (reproduces) a recorded program for a certain period of time. ) Means the case. “Recording” refers to a case where a user records by himself / herself, and this recording includes both a case where a broadcast program is recorded in real time and a case where recording is scheduled. “Delete” refers to a case where a once-recorded program is deleted (erased) without viewing it once. "Save" refers to a case where an operation of instructing to save again is performed after viewing a recorded program. "Leaving" refers to a case where a recorded program is not watched for a certain period of time.

Further, the program information to be operated is stored as the program information 35. Further, a pointer 36 to the previous record and a pointer 37 to the next record for the history information are stored. The pointer 36 to the previous record stores the data address of the record. The pointer 37 stores the address of the data of the record. When these pieces of history information 30 are accumulated in the history holding unit 24,
The CPU 11 creates preference information from the history information 30. The creation of the preference information from the history information 30 is as follows.
The preference information is created one by one when one piece of history information is accumulated in the history holding unit 24, and the accumulated amount is detected when several pieces of history information are accumulated in the history holding unit 24 (for example, a threshold is set. There is a case where preference information is created when a predetermined amount is accumulated.

FIG. 4 is a flowchart for explaining the process of creating preference information by the CPU 11. When the creation process of the preference information is started, the CPU 11 checks whether or not there is unregistered history information 30 as the preference information (Step ST).
11) If there is no unregistered information, the process of creating preference information is immediately terminated. On the other hand, when there is unregistered information, C
PU 11 searches for preference information (step ST12).
In this search processing, it is searched whether or not the same data, that is, the same data type and the same data exists in the preference information holding unit 27. Then, it is checked whether or not there is the same data (step ST13).
If there is an identical one, the current time is set as the update time (step ST14). On the other hand, step S
If it is determined in the check operation of T13 that there is no identical information in the preference information holding unit 27, a new data record is added to the preference information holding unit 27 (step ST13).
15) Then, the current time is set as the update time (step ST14). When the update time is set, the CPU 11 calculates a weight value from the operation content of the history information targeted for the current process by calculation, and adds a weight value corresponding to the process to the weight field (or Is subtracted) (step ST16), and the process of creating a series of preference information ends.

FIG. 5 is a diagram showing a calculation table serving as a basis for calculating the above weight value for performing weighting for determining the degree of preference. As shown in this figure, the weight value is determined by the weight information 20 so as to be determined by the operation performed by the user.
The data of the operation type is divided into a large classification 21 and a small classification 22. And as the large classification 21, viewing 23,
It is divided into recording 24, deletion 25, saving 26, and leaving 27,
The viewing 23 is further divided into two items as a small classification 22. As for the viewing 23, "plus one point" is provided when the user intends to view the program for a certain time or more by himself / herself.
Point ". Next, with regard to the recording 24, in the case of recording by one's own intention, it is determined to be “plus two points” both in the current recording and in the reserved recording. The deletion 25 is determined to be “minus two points” when deleting a recorded program without looking at it. The storage 26 is determined to be "plus 3 points" when instructing to save after viewing a recorded program. Regarding the abandonment 27, when a recorded program is not watched for a certain period, it is determined to be “minus one point”.

Here, the term "preference" generally means "like (like) state", but the meaning of "degree of preference" used in the present invention. Is as follows. In other words, this is simply "like"
It does not mean whether or not they are interested (whether they are interested), but what they like or do not like or whether they do not like or dislike. If the “degree of preference” is “high”, it indicates “like (love) or dislike (dislike)”, while the “degree of preference” is
"Low" means "not like or dislike".

For example, if the “degree of preference” is represented by a numerical value, and the plus (+) direction is “like” and the minus (−) direction is “dislike”, the “degree of preference” in FIG. “Low” indicates the area “C”, and “high” indicates the area “A, E”. It should be noted that the region “B, D” is considered variously depending on the case. Of course, it is naturally possible to set the area more finely and perform more detailed control.

Therefore, in the case of "destroying (deleting) information having a low degree of preference among preference information", the preference information corresponding to the above-mentioned area "C" (or areas "B, C, D") is discarded. Will be. This is because the user does not like or dislike the information, which is irrelevant. Therefore, the preference information corresponding to the area “E” (or the area “D, E”) is “meaningful information” that the user “dislikes (does not like)” and is not discarded.

The entity data (for example, the program itself)
Is a waste of capacity even if the user holds the “unfavorable”, so the target for updating or deleting the entity data is the area “E (or D, E, or C to E, or B).
.. E). In other words, the substance data to be discarded is the one with the lower “importance data (specific values of the areas A to E)”.

FIG. 7 is a diagram showing an example of the data format of the user preference information created by the above-described preference information creation processing operation. As shown in this figure, as the preference information 40, data relating to the preference is stored in various types such as an update date and time 43, a preference data type 44, specific preference data 45, and the importance 46 of the preference. ing. And the year when the preference information was updated as the update date and time 33,
Date or time information such as month, day, hour, minute, and second is stored as data. As the preference data type 44, the type of information about the program, such as the genre of the program, the cast, the series ID, the director, the time information of the program, and the channel information, is stored as data. Further, as the preference data 45, individual data corresponding to data such as a genre and a performer corresponding to the preference data type 44 is stored.
Specifically, for example, as the preference data included in the “genre” of the preference data type 44, “international film”
There are preference data such as “baseball” and “drama”, and as the preference data of the type “performer” of the preference data type 44, the name of each individual performer (talent, actor, actress, etc.) is the preference data. Is stored as Further, the weight value added (or subtracted) in step ST16 of the preference information creation processing operation is stored in the importance data 46. The pointer 47 to the previous record stores the address of the data of the target record, and the pointer 48 to the next record stores the address of the data of the target record. Further, as the pointer 47 to the previous record and the pointer 48 to the next record for the preference information, addresses of data corresponding to the respective pointers are given.

FIG. 8 is a diagram for explaining the data type 44 in the data of the preference information 40 more specifically. As shown in this figure, the data type 44 is a genre 44a and a performer 4
4b, a director 44c, an original creator 44d, IDs 44e of various series such as serial drama, a plurality of collection IDs 44f, a channel identifier, and a program frame representing data of a broadcast date and time (a start time, an end time or a broadcast time). Information 44g. Then, in general, various types of data 44 a to 44 included in these data types 44
g is associated with an ID 44h. Acquisition of such information is specified in advance as a format, and is recognized by both the sending side and the receiving side, so that acquisition of each data is possible.

FIG. 9 is a diagram showing an example in which the preference information 40 shown in FIG. 7 is represented in a list format. In this figure, the preference information 40 is represented by 40 (n), 40 (n + 1), 40 (n + 2).
... in the form of a list. And
The preference information 40 (n) stores an update date 43 (n), a genre (ID1) 44 (n) corresponding to the data type, and “baseball” 45 (n) importance data 46 (n) as preference data. . A similar data structure is adopted for the preference information 40 (n + 1). This preference information 40
For (n + 1), performer (ID2) 44 (n + 1) is stored as data corresponding to the data type, and “Taro Yamada” is stored in the preference data.

FIG. 10 is a diagram showing an example of the data content of the system holding unit data in the broadcast terminal device. As shown in the figure, the system holding unit data 50 includes recording reservation processing schedule data 51, latest recording reservation processing time data 52, and next recording reservation processing time data 53.
And the maximum recording reservation number data 54 and the maximum history data record number data 55.

FIG. 11 is a flowchart for explaining the addition and deletion processing of the preference information record by the CPU 11. When the addition / deletion processing of the preference information record is started, the CP
U11 checks whether there is room (storage area) for adding a record in the data storage unit 9 (step ST2).
1) If there is no room to add a record, a record that has already been registered is searched, and data with a low degree of preference and the oldest update date and time are not used (no viewing or the like). And delete it (step S
T22). Next, a new record is generated and added (step ST23), and then the record addition / deletion processing is terminated. On the other hand, if there is room to add a record, a new record is generated and added immediately (step ST23), and then the record addition / deletion processing ends.

FIG. 12 is a flowchart for explaining the automatic recording reservation processing by the CPU 11. When the automatic recording reservation process is started, the CPU 11 acquires the current time (step ST31), and then checks whether or not the time of the automatic recording reservation process has passed (step ST32). In this automatic recording reservation processing, the time at which the automatic recording reservation processing is performed is set and stored in the system in advance. In this case, the processing interval is arbitrary. The schedule is also set in the system in advance and stored in the setting information holding unit 25. If the time of the automatic recording reservation process has not passed in the check process, the process returns to step ST31 to acquire the current time. On the other hand, if it is determined in the check processing in step ST32 that the time of the automatic recording reservation processing has passed, it is next checked whether or not the previous processing is before the latest scheduled processing time (step ST33). In this case, the time at which the automatic recording reservation process was performed is also stored in the setting information holding unit 25. If it is determined in the check processing in step ST33 that the previous processing is not before the latest scheduled processing time, the process returns to step ST31 to acquire the current time. On the other hand, when it is determined in the check processing in step ST33 that the previous processing is before the latest scheduled processing time, the information in the preference information holding unit 27 is sorted in descending order of importance of each record (step ST34). . Next, a condition having the highest importance value is set as a search condition (step ST35), and further, program information of a stored program to be broadcasted is searched for (step ST3).
6). Next, programs that have been searched and that have not been scheduled for recording are sequentially reserved for recording up to the maximum value of recording reservations (step ST37), and then it is checked whether recording reservations have been made up to the maximum value of recording reservations. (Step ST38) If the recording reservation has been made up to the maximum value of the recording reservation, the process returns to step ST31 to acquire the current time. On the other hand, if the recording reservation has not been made up to the maximum value of the recording reservation, a condition having the next highest importance is set as a search condition (step ST3).
9) After that, the process returns to the process after step ST36. In this way, the automatic recording reservation processing is continued.

Thus, the importance of the program is determined from the tendency of the user's preference, and when a highly important program is broadcast, the broadcast terminal apparatus of the present invention automatically makes a recording reservation for the program. It is. That is, the operation of the user is scored, what kind of information the program has been viewed (the importance of the information) is determined based on the value of the score, and the program having the high score information is automatically recorded. At this time, a plurality of patterns can be considered as to what should be continuously performed for automatic recording. For example, the same series, the same genre, the same performer, the same writer, the director, etc. These patterns can be categorized in all information related to the program by the data type 44 of the preference information.

Although the recording is performed, the points are also deducted for the category of the program that is not seen, and the automatic recording can be stopped for the category that is not seen. Also, for recorded programs, if there is room in the storage medium, it is retained for a certain period of time.
Delete the oldest update date first. However, this does not apply if the user intentionally wishes to retain the information. The category of the program intended to be held in this way gives a high score when scoring as described above. In this sense, the weight information 20 shown in FIG. 5 can be variously changed with respect to the item to be weighted and the value of the weight.

Also, by collecting and analyzing such preference information for each individual, it becomes possible to automatically record a program suitable for each individual. For example, in a general household, preference information can be collected and analyzed for each individual such as a father, a mother, a brother, and oneself.

In the case of a series, programs that are continuously watched are automatically recorded. this is,
This is because the preference information is likely to be viewed before scoring according to the weight information 20. In this case, not only the program is automatically recorded when the program is recorded, but also the recording method can be changed according to the attribute of the program to be recorded. For example, if the program is a drama as an attribute of the program, additional recording is performed as a recording method. On the other hand, when the attribute of the program is news or weather forecast, overwrite recording is performed as a recording method. In this way, there are cases where a program broadcast every week, such as a drama (or series), is watched after the entire series has been shot. However, only the latest data is important, such as news or weather forecast, and old data need not be viewed, so that it is deleted when new data is recorded. As a result, the storage area of the recorded program information holding unit 22, which is a data storage unit, can be used effectively. In this case, when a program is recorded by a recording method of overwriting, after all recording is completed, the old program to be overwritten is deleted, so that neither the new nor the old data is recorded and held due to a defective recording operation. The problem described above can be avoided.

When recording a program, the recording method of the program to be recorded can be changed based on the preference information. In other words, it is possible to perform a control in which an interesting thing is additionally recorded, and recording is performed by overwriting in a case where the user is not so interested but tries to record for a trial.

As another mode, when recording a program, the bit rate at the time of recording can be changed according to the attribute of the program to be recorded. That is,
If the program is a drama or educational program, the quality of the recorded program is often required to be high, so recording is performed with a high bit rate, while programs such as news are particularly Since the definition is not emphasized, the storage area of the recorded program information holding unit 22 can be used effectively by adopting a bit rate according to the attribute of each program.

The bit rate at the time of recording a program to be recorded can be changed based on the preference information.
In other words, if you are interested, you can set a higher bit rate to record with high image quality, and if you are not interested, you can set a lower bit rate and record with lower image quality, and use the storage area effectively. .

When a broadcasted program is recorded, the program information of the program is also recorded. When a list of recorded programs is displayed, the program information is classified and displayed based on one information included in the program information. Alternatively, when displaying a list of recorded programs, the programs may be classified and displayed based on a plurality of pieces of information included in the program information. Various variations are conceivable for the list display of the programs.
That is, when displaying a list of recorded programs on a terminal that receives a program that transmits program information related to the broadcasted program and a program composed of video, audio, information, and the like, the degree of preference for each program is displayed. , Or the programs can be sorted and displayed in preference units. When the list of recorded programs is displayed, the list may be displayed in ascending order of the storage expiration date, or only unviewed programs may be displayed.
