Was. This is a recording device that records on a normal video tape while maintaining the synchronization of video and audio information to be recorded and text information multiplexed and sent. The information is recorded with the recording time and the recording position at the same time so that the program can be selectively viewed.

[0004] Conventionally, as an example of a terminal for selecting a teletext recording terminal and communication information in association with each other, there is an "information system and receiving terminal" disclosed in Japanese Patent Application Laid-Open No. 8-8859. There has been proposed a terminal for selectively viewing broadcast contents from information sent from a communication terminal. This is to selectively record and view data transmitted by data broadcasting based on a classification code given from a communication terminal.

[0005]

However, in the conventional teletext receiving terminal, the broadcast receiving terminal can only realize the reservation of the program unit and the selective viewing of the program unit determined in advance by the program provider. For example, it was not possible to specify a specific news in a news program or a specific corner of a variety program. In view of such a point, the present invention
It is an object of the present invention to provide a broadcast receiving apparatus that can automatically generate index information from character string information multiplexed on video and audio and transmitted as text multiplex broadcasting, and refer to only necessary information.

Reference numeral 4 denotes an input unit, which inputs commands necessary for operating the program selection unit 1, the program reservation unit 3, and the stored content reference unit 10 by using input means such as a remote control transceiver and panel buttons. Enter 5 is an output unit,
The video / audio and the character information reproduced by the program reproducing unit 2 and the stored contents referring unit 10 are displayed and output to a reproducing device 11 such as a monitor or a speaker.

Next, the operation will be described. The viewer uses the input unit 4 such as a remote control transmitter / receiver and a panel button attached to the broadcast receiving apparatus to input a command for designating a program to be viewed to the program selecting unit 1 of the broadcast receiving apparatus. When input, the program selection unit 1 selects a received signal from a broadcasting station that broadcasts a program in an analog broadcasting system according to this command. The program reproducing unit 2 demodulates the received signal from the selected broadcasting station, reproduces a video signal and an audio signal, and sends the reproduced signal to the output unit 5. The output unit 5 outputs the demodulated signal to a reproduction device 11 such as a monitor such as a CRT or a speaker.
, And the viewer watches the video and audio reproduced by the reproducing device 11.

The above is a case where the program desired to be viewed is not a text multiplex broadcast (hereinafter referred to as a text broadcast) but a broadcast of normal video / audio information. When the viewer operates the input unit 4 to specify the reception of the teletext, the reproducing device 11 reproduces the still image including the text information transmitted by the teletext.

That is, the program selecting unit 1 selects a teletext signal from a station broadcasting a teletext program in accordance with a command from the input unit 4. The program reproducing unit 2 decodes the character information superimposed on the gap between the teletext video signals and outputs it to the output unit 5. The playback device 11 projects a still image including the character information output from the output unit 5.

FIG. 2 shows an example of an image received from a teletext and displayed on a monitor. Such an operation is the same as that in the case of receiving a teletext in a normal teletext compatible television receiver. However, the apparatus according to the first embodiment has a function of automatically selecting only information on a theme desired by a viewer from teletext and displaying the information.

That is, when the viewer operates the input unit 4 and selects a desired teletext program in the program selection unit 1, the program reproduction unit 2 stores the demodulated text still image video audio signal demodulated by the video audio storage unit. 6 and the character information is stored in the character information storage unit 7. At this time, the character information storage unit 7 converts the video / audio signal stored in the video / audio storage unit 6 into a frame serving as a basic unit when dividing the video / audio signal by recognizing a break in the character information included at the beginning. Is extracted, and the character information is stored in units of pairs of the frame information and the corresponding character information using the frame information as an index. Note that the program playback unit 2
If there is no character information to be reproduced in step (1), the character information storage unit 7 may determine a frame by detecting in advance a break in audio information or a break in steady video information indicating switching to a commercial.

The segment judging section 8 judges that the program has been switched based on the character information stored in the character information storing section 7, and divides the program contents into segments consisting of a series of character information. The segment determination may be performed by the segment determination unit 8 itself by recognizing a change in the content of the character information. However, the segment determination unit 8 identifies the start of the segment that has been superimposed on the character information in advance by the broadcasting station. The segment break may be determined using the tag information to be performed. The segment accumulating unit 9 accumulates segments in units of pairs of the character information and the corresponding segments using the character information appearing at the time of switching of the program or program contents from which the segment is obtained as an index. The storage content reference unit 10 extracts an identifier specified by the viewer operating the input unit 4 from the segment storage unit 9, and transmits the character information at the head of the frame constituting the segment to the playback device 11 via the output unit 5. The video and audio signals of the still image corresponding to the frame information designated by the viewer are taken out from the video and audio storage unit 6 by displaying and operating the input unit 4.
Thus, the output unit 5 outputs the video / audio signal of the still image to the playback device 11, and the playback device 11 plays back the still image.

FIG. 3 shows a frame image of information obtained by receiving teletext and an image of information stored by dividing the frame image. a indicates an image of a teletext broadcast obtained by time slicing, that is, an image of the teletext transmitted in time units, and a01 to a06 and a11 indicate respective screen information of the teletext transmitted in a predetermined time unit. . b shows the image of the video / audio signal when the respective screen information of the teletext is stored in the video / audio storage unit 6 of FIG. 1, and c shows the screen information broadcast during the teletext program. On the other hand, character information stored in the frame unit is represented, and c01 to c06 and c11 indicate character information included in the titles of the screen information a01 to a06 and a11, respectively. d is segment information included in a segment of the still image video a transmitted in time units of the text broadcast, which is separated by an empty portion having no character information.

FIG. 4 shows a management content image of the segment information, which has a character string appearing on the top screen as an identifier.
4 illustrates an example of an image that manages addresses of a head position of video / audio information and a storage position of a character string. In the figure, <
1>, <2>, <3>, <4>, and <5> are numbers sequentially assigned to character strings extracted from the frame of the first screen appearing at the beginning of each segment delimited by a screen having no character information. The figure also shows an example of a head address of the video / audio storage unit 6 for each segment and an example of a head address of the character information storage unit 7 for each segment, in which frames constituting each segment and character strings included in each segment are stored. .

FIG. 5 is a flow chart showing a segment dividing method executed by the segment judging section 8. The method is as follows. That is, in step S1, character information is input from a frame, and in step S2, it is determined whether or not the program has ended. If the program has not ended, in the next step S3, the character information is set to 'NIL
L ′, that is, the presence or absence of character information is detected. If the character information is not "NILL", that is, if the character information exists, it is determined in step S4 whether or not the presence flag indicating the state with the character information is 0. In the present flow, since the existence flag is set to 0 at the time of the start, the process proceeds from step S4 to step S5. Step S5
, The presence flag is set to 1, the storage of the character string is started, the storage position of the video is stored, the character string identifier is registered, and the process returns to step S1.

After returning to step S1, the above processing is repeated. If it is determined in step S4 that the presence flag is 0, a character string is added in step S6 and the process returns to step S1. Step S3
In step S7, if it is determined that the character information is "NILL", it is determined in step S7 whether the presence flag is 0. If it is determined that the presence flag is 0, the process returns to step S1. If it is determined in step S7 that the presence flag is not 0, the presence flag is set to 0 in step S8, and the process returns to step S1.

By repeating these processes, a character string is extracted from a still image transmitted by teletext, and the character string is stored in segment units. If the program ends during the repetition of the above processing, the process branches from the series of processing loops in step S2 to end the segment division processing.

Then, only the segment unit character information is output from the segment storage unit 9 via the output unit 5 to the reproduction apparatus 11.
And the viewer operates the input unit 4 to input a keyword corresponding to the content of the screen desired to be viewed as a command, so that the stored content referring unit 10 stores the characters stored in the segment storage unit 9 in segment units. The information and the keyword input from the input unit 4 are matched. And
The output unit 5 outputs the segment-based character information matched with the keyword to the reproducing device 11, and the reproducing device 11 displays the character information matched with the keyword specified by the viewer on a monitor screen.

FIG. 6 shows an example of an image in which the user selectively selects and views a part of the program information as a result of executing the segment division. In the example of FIG. 6, character information <1> to <5> in segment units are displayed as buttons B.
Further, the figure shows that the teletext screen of the frame corresponding to <2> is retrieved from the video / audio storage unit 6 and displayed in the window W because the viewer has specified <2> among them.

As described above, according to the first embodiment, the character information related to the theme that the viewer wants to view can be automatically extracted from the program and displayed. It is possible to view the target information promptly without the need to temporarily record it on a video or the like and then fast forward it to search for desired contents.

Further, since the broadcast receiving apparatus according to the first embodiment includes a large-capacity HDD or DVD-RAM,
In addition to the function of automatically detecting character information corresponding to a keyword as described above, a so-called playback TV function can be added.

That is, the playback TV can reproduce the part that was overlooked in the part immediately before the part to be watched, and the reproduction contents gradually approached the current broadcast contents, and the reproduction contents caught up with the current broadcast contents. At this point, it switches to the playback of the received broadcast, so that the missed part can be played back retroactively, and in order to realize such a playback function, a large amount of information constituting the image is stored. In addition, it is necessary to reproduce the stored information at a higher speed than at the time of recording. This can be realized by using a large-capacity storage device such as an HDD, which is used for automatically detecting the character information described above. Is possible.

Therefore, it is possible to add a function of automatically extracting broadcast contents corresponding to the above-mentioned keywords to a playback TV realized by using an HDD or the like, thereby further increasing the added value of the playback TV. Is possible.

The program selection as described above is performed by the viewer operating the input unit 4 and inputting a command for program reservation, so that the program reservation unit 3 sends the program selection unit 1 and the program reproduction unit 2 with each other. On the other hand, it is also possible to perform a reservation operation so that a program of a specified station is selected at a specified time and reproduced, and in a state where such a program reservation is made, a keyword which is expected to be broadcast is viewed. It is of course possible for a user to input the information in advance and to set the desired broadcast content to be automatically extracted.
