[0006]

The digital broadcast receiving apparatus having the configuration shown in FIG. 8 has no particular problem in receiving digital broadcasts in real time.

[0007] However, the user does not always watch the digital broadcast in real time. If the user broadcasts a program desired by the user during a time when the user cannot view the digital broadcast, a program recording device such as a VTR is required separately. . In addition, multi-channel is one of the major features of digital broadcasting.
However, since the amount of program information becomes enormous in proportion to the number of channels, selecting a favorite program from a huge amount of program information imposes a heavy burden on the user. . Furthermore, the program information is not always transmitted before the broadcast starts, and the program information may be transmitted simultaneously with the start of the broadcast. For such a program, whether or not the user should view in advance I can't judge.

[0008] The present invention has been made in view of the above points,
The aim is to create a digital broadcast receiver that can automatically store programs that match the user's preference and simply play back the stored data simply by the user registering the keywords of the favorite programs in the receiver. To provide.

[0009]

In order to achieve the above object, a digital broadcast receiving apparatus according to the present invention comprises, for example,
Data separating means for separating data such as video, audio and information from multiplexed digital data; data storing means for storing data such as video, audio and information separated from the data separating means; and a keyword input by a user A program keyword storage unit for storing program information, a program information analysis unit for analyzing program information from the separated information data, and a comparison between information stored in the keyword storage unit and the program information analysis unit. Control means for determining whether or not to store data such as sound and information, and based on an instruction from the control means, data such as video, audio and information of a program matching the keyword registered in the keyword storage means. ,
It is configured to automatically accumulate in the data accumulating means.

Here, the configuration shown in FIG. 1 shows a part of the receiving apparatus. In practice, a signal transmitted from a broadcasting station is formed by using various techniques such as digital modulation and error correction. In order to be transmitted, means corresponding to these technologies is indispensable in a stage preceding the input terminal 101, and such means is provided in the receiving apparatus 100 of the present embodiment. In addition, the above-described remote control signal receiving unit, an IC card, a configuration attached thereto, and the like shown in FIG. 8 are also provided in the receiving device 100 of the present embodiment.

In the configuration shown in FIG. 1, a keyword previously input by a user is registered in the program keyword registration table 104. This keyword is
This is information for identifying a program for which the user requests automatic accumulation. For example, the genre, program name,
Performers, performers, channels and the like can be set.

Next, a first example of the data automatic storage processing flow in this embodiment will be described with reference to FIG.

In a state where a digital broadcast of a certain channel is being received, when it is recognized that the broadcast of the next program has not started (when program information prior to the broadcast of the next program is received), first, In step ST1, it is determined whether or not the user is watching a program. This judgment is
For example, the control block 106 can determine whether the video / audio decoding circuit 110 is decoding a video / audio signal while receiving a digital broadcast. If the user is not watching, the process proceeds to the next step ST2. If the user is watching, the data automatic accumulation processing flow is terminated, and the start timing of the next data automatic accumulation processing flow is waited.

In step ST2, the program information analysis block 105 analyzes the genre and contents of the program to be broadcast next based on information data such as program information data extracted from the received data. Then, in the next step ST3, the control block 106 compares the analysis result of the program information analysis block 105 with the contents of the program keyword registration table 104, and compares the keyword registered in the program keyword registration table 104 with the program information analysis. If the analysis result of block 105 matches, the next step S
The process proceeds to T4, and if they do not match, this data automatic accumulation processing flow is terminated, and the start timing of the next data automatic accumulation processing flow is waited.

In step ST4, control block 106
However, based on the remaining capacity of the data recording medium 107 and the length (capacity) data of the program in which the above-mentioned keyword matches (this is data obtained from the program information data), the remaining capacity of the data recording medium 107 is It is determined whether or not it is sufficient to accumulate all the data of the program. If YES, proceed to the next step ST5, if NO, end this data automatic accumulation processing flow and proceed to the next data automatic accumulation processing flow. Wait for start timing.

In step ST5, control block 106
Causes the data of the program, that is, data such as video, audio, and information, to be recorded (stored) in the data recording medium 107 from the beginning to the end of the program, and the next step ST6
After the storage of the program data is completed, the control block 106 causes the stored program information registration table 108 to register identification data for identifying the program whose storage has been completed, and proceeds to the next step ST7. The identification data stored in the stored program registration table 108 includes, for example,
A broadcast date and time, a broadcast channel, a program name, a program length, a keyword, the presence or absence of billing, and the like can be considered.

In step ST7, a preparation is made to notify the user that the data of the program with the matching keyword has been automatically stored or that the data has been stored automatically. That is, the fact that the automatic accumulation has been performed is notified by blinking of the LED, and the fact that the automatic accumulation has been performed is displayed as character information on the display screen during a predetermined second when the monitor screen is turned on next. To be performed is stored in a predetermined storage area. Thus, when the display of the monitor screen is turned on next, the control block 106 stores the data registered in the stored program registration table 108 into the OSD circuit 111.
Is generated as display character information, and this is mixed with the video signal by the mixer 112 and displayed on the display screen for a predetermined time. Then, after the completion of the process of step ST7, the data automatic accumulation processing flow is ended, and the start timing of the next data automatic accumulation processing flow is waited.

According to the processing flow of FIG. 2, a user registers a keyword of a favorite program in advance, so that a program according to the user's preference is automatically performed when the user is not watching a broadcast. Can be accumulated.

Next, a second example of the automatic data storage processing flow in this embodiment will be described with reference to FIG.

When it is recognized that the digital broadcast of a certain channel is being received before the start of the broadcast of the next program (when program information prior to the broadcast of the next program is received), first, In step ST11, it is determined whether or not the user is watching a program. If YES, the process proceeds to the next step ST12, and if NO, the process proceeds to step ST1.
Jump to 3. In step ST12, it is determined whether or not automatic accumulation processing is set to be performed even during viewing of a program (broadcast).
Proceeding to T13, if NO, end this data automatic accumulation processing flow and wait for the start timing of the next data automatic accumulation processing flow.

The processing after step ST13 is exactly the same as the processing of steps ST2 to ST7 in FIG. 2 described above, and a description thereof will be omitted.

According to the processing flow of FIG. 3, the user registers the keyword of the favorite program in advance, so that the program according to the user's preference is automatically performed when the user is not watching the broadcast. It is possible to accumulate, and if it is set to perform automatic accumulation processing even while watching a broadcast, a program according to the user's preference is automatically accumulated even while watching a program can do.

Next, a third example of the data automatic storage processing flow in the present embodiment will be described with reference to FIG.

If it is recognized that the digital broadcast of a certain channel is being received before the start of the broadcast of the next program (when program information prior to the broadcast of the next program is received), step ST21 is performed. Is performed. The processing of steps ST21 to ST23 of this example is completely the same as the processing of steps ST1 to ST3 of FIG.
The description is omitted.

In step ST24, based on the remaining capacity of the data recording medium 107 and the length (capacity) data of the program whose keyword matches, the remaining capacity of the data recording medium 107 is sufficient to store all the data of the program. It judges whether or not it is a thing, and when it is NO, it progresses to step ST25,
If YES, the process proceeds to step ST26. Step ST25
Then, when the remaining capacity of the data recording medium 107 is insufficient, it is determined whether or not it is set to overwrite recording on the data recording medium 107. If YES, the process proceeds to step ST26. And waits for the start timing of the next data automatic accumulation processing flow.

The processing after step ST26 is exactly the same as the processing of steps ST5 to ST7 in FIG. 2 described above, and a description thereof will be omitted.

According to the processing flow of FIG. 4, a user registers a keyword of a favorite program in advance, so that a program according to the user's preference is automatically performed when the user is not watching a broadcast. It is possible to accumulate, and by setting overwriting when the remaining capacity of the data recording medium 107 is insufficient, all data of the latest automatically selected program can be reliably accumulated. it can.

Each of the processing flows shown in FIGS. 2 to 4 is based on the premise that the program information of the next program is broadcasted before the broadcast of the next program. Even if data accumulation is started after judging match / mismatch, the program data is not hindered (without omission)
Can be stored (data can be stored simultaneously with the start of a program). However, there is a service in which the program information is not transmitted before the broadcast of the program, and the program information is transmitted simultaneously with the video / audio data of the program.

Referring to FIG. 5, a fourth example of a data automatic storage processing flow according to the present embodiment for coping with such a service will be described.

First, when a certain program is started to be broadcast in a state where a digital broadcast of a certain channel is being received, first, in step ST31, it is determined whether or not the user is watching the program. Ends the data automatic accumulation processing flow and waits for the start timing of the next data automatic accumulation processing flow. In the case of NO, the process proceeds to step ST32 to start a data accumulation operation for accumulating the broadcast-started program data from the beginning.
That is, when the user is not watching the program, the storage of the received program is started unconditionally, and step ST
Go to 33.

In step ST33, the genre and contents of the program being received / stored are analyzed based on the program information data extracted from the received data of the program whose storage has started, and the process proceeds to the next step ST34. In step ST34, the analysis result of step ST33 is compared with the contents of the program keyword registration table 104, and it is determined whether or not the keyword registered in the program keyword registration table 104 matches the analysis result of step ST33. , Y
If ES, the process proceeds to the next step ST34, and if NO, the process jumps to step ST40.

In step ST34, based on the remaining capacity of the data recording medium 107 and the length (capacity) data of the program whose keyword matches, the remaining capacity of the data recording medium 107 is sufficient to store all the data of the program. It is determined whether or not it is the one. If NO, the process proceeds to step ST36,
If YES, the process proceeds to step ST37. Step ST36
Then, when the remaining capacity of the data recording medium 107 is insufficient, it is determined whether or not the overwriting recording is set on the data recording medium 107. If YES, the process proceeds to step ST37, and if NO, the process proceeds to step ST40.

In step ST37, the program data accumulation operation is continued, and when the program data has been completely stored, the operation proceeds to step ST38. Step ST38, ST
The processing in step 39 is exactly the same as the processing in steps ST6 and ST7 in FIG. 2 described above, and a description thereof will be omitted.

In step ST40, the program data storage operation is stopped. In the next step ST41, the stored data of the program whose storage operation has been stopped is deleted from the data recording medium 107. And waits for the start timing of the next data automatic accumulation processing flow.

According to the processing flow shown in FIG. 5, the program information is not transmitted before the broadcast of the program, and the program information data is transmitted simultaneously with the video and audio data of the program. It becomes possible to accumulate program data from the starting point.

Next, a first example of the stored data reproduction processing flow in the present embodiment will be described with reference to FIG.

When the stored data reproduction processing flow is started, the identification data of the stored program stored in the stored program information registration table 108 is displayed on the display screen by the OSD function under the control of the control block 106. Is done. In this state, in step ST51, it is determined whether or not the user has selected the desired storage data. If the user has selected the desired storage data, the process proceeds to step ST52. If the user has not selected the storage data, the process proceeds to step ST52. For example,
When an operation to erase the display screen of the identification data of the stored program is performed), the stored data reproduction processing flow is ended.

In step ST52, the control block 106, which has received a selection / reproduction request from the stored data of the user via the input terminal 114, sets the switching circuit 10
9 is switched to the data storage medium 107 side, and the data of the stored program designated by the user is output from the storage medium 107 to the video / audio decoding circuit 110 to reproduce the data of the stored program (video display and video display). Sound output).

Step ST53 following step ST52
Then, it is monitored whether or not the reproduction of the designated stored data is completed (it is determined whether or not the reproduction condition of the stored data is satisfied).
The processing routine of steps ST52 and ST53 is repeated, and when it is considered that the reproduction of the stored data has been completed, the process proceeds to step ST54.

In step ST53, for example, when the stored program has been viewed to the end, or when a specific time has elapsed since the reproduction was started even if the program was not viewed to the end, Reproduction is considered to be completed based on conditions such as when the time limit for viewing is determined and the time limit has passed.

In step ST54, the identification information corresponding to the stored data whose data reproduction has been completed is deleted from the stored program information registration table 108, and the next step S54 is executed.
At T55, the stored data of the program whose data reproduction has been completed is deleted from the data storage medium 107, and then the stored data reproduction processing flow ends.

According to the processing flow of FIG. 6, for example, even if the user cannot view the program at the time of broadcasting, the user can view the automatically stored favorite program once at the timing desired by the user. Can be. Furthermore, in this example,
Since the data storage medium 107 is built in the receiving apparatus 100 and the data stored in the data storage medium 107 is automatically deleted after the viewing is completed, the broadcaster can view the data. There is no problem in terms of fees.

In the stored data reproduction processing flow shown in FIG. 6, once the stored program is viewed once, the stored program data is automatically deleted. If you want to watch it again, you cannot deal with it.

FIG. 7 shows a second example of the stored data reproduction processing flow according to the present embodiment which can cope with such a case.
This will be described with reference to FIG.

When the stored data reproduction processing flow is started, the identification data of the stored program is displayed on the display screen by the OSD function. In this state,
Steps ST61 to ST63 are executed. The processing of steps ST61 to ST63 is completely the same as the processing of steps ST51 to ST53 in FIG.
The description is omitted.

Step ST64 following step ST63
Then, the user is asked whether or not to store the data of the reproduced and viewed program in the data storage medium 107. If the user desires to save the data, the process proceeds to step ST65.
If the user does not wish to save, the process jumps to step ST70.

In step ST65, the control block 106 refers to the information data of the program desired to be stored and, once viewed, cannot be stored in the data storage medium 107 unless a fee payment procedure is performed. It is determined whether or not the data is program data. If YES, step ST6
The process advances to step ST68 if NO. Such a mechanism for permitting re-viewing with separate charging is added to, for example, the stored program data and the control block 106, and once the process of reading out the program data from the data storage medium 107 is executed, the re-viewing is performed. If the fee payment procedure is not performed, the program data is automatically erased.

In step ST66, the user is informed that a fee must be paid to store and maintain the data of the program desired to be stored in the storage medium 107.
In the next step ST67, it is determined whether or not the user has performed a fee payment procedure.
The process proceeds to 68, and if NO, proceeds to step ST70. In addition,
Payment procedure (notification of billing, etc.)
Is directly notified to the broadcaster in the case of two-way communication, and in the case of no two-way communication, the accounting information is aggregated using, for example, the IC card 514 described above. Becomes

In step ST68, the control block 106 refers to the information data of the program desired to be stored, and once viewed, the program data whose storage in the data storage medium 107 is completely prohibited. It is determined whether or not the program data is copy-free program data, and the process proceeds to step ST72. If the re-viewing is prohibited program data regardless of whether a fee is paid, the process proceeds to step ST69. .

In step ST69, the user is notified that the program data is completely prohibited from being re-viewed,
Proceed to step ST70.

In step ST70, step S70 in FIG.
As in the process of T54, the identification information corresponding to the stored data whose reproduction has been completed is deleted from the stored program information registration table 108, and in the next step ST71, the data reproduction is performed in the same manner as the process of step ST55 in FIG. Deleting the stored data of the completed program from the data storage medium 107;
After that, the stored data reproduction processing flow is terminated.

On the other hand, in step ST72, processing for storing and maintaining the reproduced program data in the data storage medium 107 is performed. In the next step ST73, the stored program registration table 108 stores the identification data of the stored and maintained program. Is re-registered by adding re-registration date and time information and the like as necessary. In the next step ST74, the
A process similar to the process of T7 is performed, and thereafter, the stored data reproducing process flow ends.

According to the processing flow of FIG. 7, for example, even if the user cannot view the program at the time of broadcasting, he / she views the automatically stored favorite program at least once at a timing desired by the user. be able to. Further, in this example, if the user desires to view again, the program is determined according to whether the program is a copy-free program, a program that cannot be re-viewed for free due to copyright law, or a program that cannot be re-viewed at all. Therefore, whether the program is to be deleted or stored continuously is automatically selected appropriately, so that it is convenient for the user and also disadvantageous to the broadcaster side. Will not be.

The program keyword described in the above-described embodiment is an example of information for identifying a program. Even if a program identifier dependent on or independent of a broadcaster, a program identification flag, or the like is used. Similar effects can be obtained. Also,
The data storage media described in the above embodiments are not particularly limited, such as hard disks, optical disks, magnetic tapes, and semiconductor memories.

In this embodiment, the receiving device has only one data storage medium (built-in). However, a plurality of data storage media (and associated driving devices) may be mounted. In this case, program data of a plurality of channels can be simultaneously stored.

It should be noted that a combination of a plurality of keywords may be set as a condition for the automatic accumulation. In such a case, fine automatic program selection becomes possible.

[0059]

As described above, according to the present invention, a user simply registers a keyword of a favorite program in a receiving device, and automatically accumulates a program that meets the user's preference, and obtains the timing desired by the user. Thus, it is possible to realize a digital broadcast receiving apparatus capable of viewing the stored program.
