Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an outline of the configuration of the television receiver according to the embodiment of the present invention. In the description of the block diagram in the present invention, the arrows connecting the blocks indicate that there is a flow of data and signals between the blocks and the direction of the flow. According to each embodiment described later, this means that data and signals flow or do not flow.

  A01 is a storage unit for storing data for configuring an electronic program guide (electronic program guide data), video data for the purpose of notifying a predetermined program (preview video data), and the like. Here, although described as video data for convenience, the video data includes any of video only data, audio only data, or data consisting of both video and audio. Each preview video data is included in the video data, and each video is given a unique preview video data ID and stored in the storage unit A01. For example, when the storage unit A01 stores various data as files and saves with different file names for each preview video data, the file name of each preview video data becomes the preview video data ID. In the following description, the storage unit A01 is assumed to store a different file name for each preview video data. However, the preview video data ID may be assigned by any other method.

2A and 2B are schematic diagrams showing an example of a specific format of electronic program guide data. The electronic program guide data is composed of a plurality of pieces of program information, and usually includes all program information for about one day to one week from the current date and time for channels that can be received by the television receiver.
FIG. 2C is a schematic diagram showing an example of the format of each program information. The program information shown in FIG. 2C is composed of a total of seven fields: channel ID, broadcast start date / time, program time length, genre, series name, program name, and program description. It may be a configuration. Here, the channel ID is information for uniquely identifying a channel, and specifically indicates a channel number, a broadcaster name, and the like. In the program description, the contents of the program, names of performers, and the like are described as character data. In the following description, the format of the program information is as shown in FIG. 2C unless otherwise specified.
FIG. 3 is a schematic diagram showing a specific example of electronic program guide data in the format shown in FIGS. 2 (a), 2 (b), and 2 (c). EJ01, EJ02, EJ03, EJ04, EJ05, EJ06, and EJ07 are program information constituting electronic program guide data. In the example of the electronic program guide data shown in FIG. 3, on each channel, the program starts broadcasting at 2006/3/1 00:00:00, 2006/3/1 12:00, 2006/3/2 00:00:00. And only one is broadcast every 12 hours.

  A02 receives a television broadcast wave and at least one channel setting signal as input, extracts broadcast data for the channel corresponding to the channel setting signal from the broadcast wave, and uses the broadcast data as video data and non-video data. It is a receiving part which outputs separately. Here, as shown in FIG. 4, non-video data refers to all data other than video data multiplexed in the broadcast data of each channel, and is broadly related to the video data. There are two types, one that is multiplexed (video-related non-video data) and one that is multiplexed independently of the video data (video-related non-video data).

  As specific examples of the non-video data, the video-related non-video data includes a channel ID indicating which channel is broadcast data, a current date and time, and current program information (programs about programs being broadcast). Information), and non-video data unrelated to video includes electronic program guide data. The electronic program guide data is, for example, program information related to a program scheduled to be broadcast for one week ahead of all channels, and is the original data when displaying an EPG (Electronic Program Guide). Of the non-video data output by the receiving unit A02, at least only the electronic program guide data is stored in the storage unit A01.

  A03 receives video data and non-video data as input, extracts and outputs only the preview video data included in the video data by a predetermined method, and also provides a program ID (predicted by the program predicted by the preview video data). It is a notice related information extracting unit that outputs (identification of a program). Here, the program ID refers to an identifier for specifying predetermined program information in the electronic program guide data. The format of the program ID may be exactly the same as the format of the program information, but may be the minimum information necessary to uniquely identify the program. For example, when the format of the program information constituting the electronic program guide data is as shown in FIG. 2C, information consisting of three fields of channel ID, broadcast start date and time, and program time length is used as the program ID. , The program can be uniquely identified.

  Further, the notice related information extraction unit A03 acquires electronic program guide data from the storage unit A01 as necessary. Furthermore, the advance notice related information extraction unit A03 outputs a channel setting signal to the reception unit A02 as necessary. Here, when the receiving unit A02 accepts two or more channel setting signals, the receiving unit A02 receives video data and non-video data for the channel corresponding to the channel setting signal received from the notice related information extraction unit A03 as notice related information. Output to the extraction unit A03. The more detailed operation of the notice related information extraction unit A03 will be described in each of the specific first to third embodiments described later.

  A04 is input with the preview video data, the program to be previewed (identification of the program to be predicted), and the electronic program guide data, and the preview for controlling to store the preview video data and the preview video / preview program related information in the storage unit A01. This is a video storage control unit. Here, the notice video / predicted program related information is information for associating the notice video data with program information about the noticed program in the electronic program guide data. For the preview video / predicted program related information, for example, by specifying the preview video data, the program information of the corresponding predicted program in the electronic program guide data is read, or conversely, the program information in the electronic program guide data is read out. It is used for the purpose of reading the corresponding notice video data by specifying. Note that the preview video storage control unit A04 may serve to delete the unnecessary preview video data and the preview video / preview program related information. For example, notice video data and notice video / pre-warned program related information for a program that has already been broadcast is usually unnecessary, so it can be deleted from the storage unit A01 to secure a finite free space in the storage unit A01. preferable.

  FIG. 5A is a schematic diagram illustrating an example of a storage format of information related to a preview video / pre-warned program. EL03 is program information in which the field of the preview video data ID is added to the program information EJ03 in the electronic program guide data shown in FIG. When the preview video storage control unit A04 stores the preview video data for the program corresponding to the program information EJ03 in the storage unit A01, for example, with the file name “033.mpg”, the preview video data file is used as the preview video data ID. The name “033.mpg” is added to the program information EJ03 in the electronic program guide data to form the program information EL03, which is then stored again in the storage unit A01. Thus, by adding and storing the preview video data ID as one field of program information, the preview video data and the program information about the program to be predicted in the electronic program guide data are associated with each other.

  FIG. 5B is a schematic diagram showing another example of the storage format of the notice video / predicted program related information. EL01 and EL02 are both information related to the notice video / predicted program. In FIG. 5 (b), unlike the saving format shown in FIG. 5 (a), the notice video / predicted program-related information is saved independently from the electronic program guide data. The data cannot be associated with the program information about the program to be noticed in the electronic program guide data. Therefore, in addition to the notice video data ID, a program ID for specifying the program information corresponding to the notice video data from the electronic program guide data is used as the notice video / predicted program related information.

  The notice video storage control unit A04 may convert the notice video data into an appropriate format and save it in the storage unit A01 as necessary. For example, when the format of the preview video data is analog and the storage unit A01 can only store digital data, the preview video storage control unit A04 performs AD conversion on the preview video data and then stores it in the storage unit A01. Further, even when the format of the preview video data is digital and the storage unit A01 can store the digital data, if the size of the preview video data is large and cannot be stored in the storage unit A01 as it is, it is compressed. Save from.

A preview video selection unit that outputs a preview video data ID.

  A06 is a user input unit that takes a user operation as an input and controls the receiving unit A02, the preview video selection unit A05, and the like. For example, when the user performs a channel selection operation, the receiving unit A02 is controlled by outputting a channel setting signal corresponding to the channel selected by the user, and the video data and non-video data of the channel desired by the user are broadcast. Operate to extract from waves. Further, when the user performs selection operation or playback operation of the recorded preview video data, the user operation signal corresponding to the user operation content is output to control the preview video selection unit A05, and the user's desired Perform the action.

A07 is a preview video reproduction unit that inputs a preview video data ID, reads the preview video data corresponding to the preview video data ID from the storage unit A01, reproduces it, and outputs a playback preview video.
A08 is a composite video output unit that inputs a playback preview video or a UI video and outputs one or both of the two videos.
A09 is a program guide acquisition unit that acquires electronic program guide data from the non-video data received from the receiving unit A02 and stores the electronic program guide data in the storage unit.

The television receiver according to the embodiment of the present invention has roughly two operation phases. One is an operation phase (first operation phase) for storing and collecting various preview video data, and the other is a phase (second operation phase) for selecting and reproducing the collected preview video data. It is. Note that the two operation phases may be executed simultaneously.
Here, since the first operation phase largely depends on the operation content of the notice related information extraction unit A03, it will be described in specific embodiments described later.

Here, the program information being received does not necessarily include all the fields of the program information constituting the electronic program guide data as shown in FIG.
FIG. 2D is a schematic diagram showing an example of a format of program information being received. In the format of the program information being received shown in FIG. 2 (d), the program description field is omitted from the format of the program information shown in FIG. 2 (c).

  B13 is a preview video extraction unit that receives video data and receiving program information as input, and extracts and outputs the preview video data for notifying the next broadcast content from the video data by a predetermined method. The predetermined method may be, for example, a method of extracting video data for a predetermined time just before the end of the program as notice video data, or any other method. Note that not all of the programs include notice video data, so as a predetermined condition for the program information, the notice video data from only the video data for a program having a predetermined genre or a predetermined program name in the program information. It is desirable to extract and output. For example, for a program whose genre is drama, there is a high possibility that the video data includes the preview video data related to the next broadcast, while a program whose genre is news may not include the preview video data related to the next broadcast. It is a fact that is well known from experience.

FIG. 11A is a schematic diagram showing an example of the configuration of video data of a program handled by the television receiver according to the embodiment of the present invention. The video data shown in FIG. 11A is composed of a main video, a CM video, a net preview video, and a CM video in order from the broadcast start time.

The receiver A02 is set to receive the channel described in the channel ID of the program information, and the video data being received is continuously output as the preview video data until the broadcast end date and time is reached. The notice video extraction unit D31 has a program name field that is the same as the program name field of the program information and the program information whose genre name is not a program notice is an electronic program as the noticed program information corresponding to the notice video. Search from the table data, and generate and output the TV program ID to be notified from the TV program information.

FIG. 18 is an operation flowchart when the television receiving apparatus according to the third embodiment of the present invention performs processing in the first operation phase.
The process of the flowchart shown in FIG. 18 is called periodically at a predetermined time interval TU01, or is called at the timing when the current date / time becomes the broadcast start date / time or broadcast end date / time of any notice video. The broadcast start date and time and broadcast end date and time of the preview video can be obtained or derived from program information about the preview video in the electronic program guide data.

After the start of the process, first, the notice video extraction unit D31 determines whether or not the current date and time is the broadcast start date and time of a predetermined notice video (step SU01).
When it is determined in step SU01 that it is “broadcast start date and time” (step SU01 / YES), the preview video extraction unit D31 outputs a channel setting signal to the reception unit A02 so as to receive the channel on which the preview video is broadcast. After that, the notice video storage control unit A04 starts saving the notice video data in the storage unit A01 (step SU02), and the process is terminated.

Determination is made (step SU04). If it is determined in step SU04 that “not stored” (step SU04 / NO), the process is terminated.
On the other hand, if it is determined in step SU04 that it is “saving” (step SU04 / YES), the preview video extraction unit D31 stops storing the preview video data and stores the preview video / previewed program related information. After saving in the part A01 (step SU05), the process ends.

  In addition, when the receiving unit A02 accepts only one channel setting signal at the same time, it is not preferable that the notice video extracting unit D31 arbitrarily changes from the channel set by the user to another channel. Therefore, in this case, the video extraction unit D31 may store only the preview video for the currently set channel without changing the channel received by the reception unit A02. On the other hand, during the storage of the preview video data, it is desirable to prohibit the change of the reception channel by the user input unit A06, or forcibly execute step SU05 when the reception channel is changed to end the storage of the preview video data.

  Even when the receiving unit A02 receives a plurality of channel setting signals at the same time, if a number of notice videos exceeding the number of receivable channels are broadcast on different channels at the same time, a priority order is assigned by a predetermined method. Thus, it is desirable to store only the preview video data for the high priority channel. The predetermined method includes, for example, a method of preserving the user's viewing status in each channel and giving priority to a channel with a high audience rating, or lowering the priority for a program that has already saved the preview video data. Although a method is conceivable, the priority order is not limited to the above-described method, and a priority may be set by any method.
