  In conventional television reception systems, there is no means to reliably acquire correction information corresponding to a scene including erroneous contents. Therefore, when a scene including erroneous contents is viewed or recorded, correction information by superimposing characters or sound is used. If the user does not watch or record the video, the viewer cannot know that the content is wrong, and there is a problem that the user may believe the wrong content.

  Also, if you record a scene that contains incorrect content, even if you watch the correction information by superimposing or voice, if you do not record it, it will be corrected when you replay the scene that contains incorrect content at a later date. There was a problem that there was a high possibility of forgetting, and there was a risk of believing the wrong contents again.

  In addition, when a program containing incorrect contents is recorded, even if the correction is made by superimposing or sound, the scene containing the incorrect contents and the scene containing the correction information are recorded apart from each other in time. If it was recorded on the recording media, only the scenes containing the wrong contents could be played back, and the scenes containing the correction information could not be played back, so there was a problem that the wrong contents could be believed again .

(Example 1)
FIG. 1 is a hardware block diagram of a typical digital television receiving system.

  In FIG. 1, a receiver unit 1 is a unit that performs data input / output, processing, storage, communication, and the like. The display may be integrated with the receiver unit 1.

  When the viewer selects a channel using the remote controller 5, the received data of the desired channel is obtained by the tuner 2 from the signal input from the antenna or the CATV terminal. Since the reception data of one channel in the digital television is multiplexed with video data, audio data, and other code data, the CPU 3 separates these data and stores them in the memory 6 respectively. The CPU 3 performs decoding and other processing on each data in the memory 6 and outputs video and audio to the display via the display I / F 4.

  The data stored in the memory 6 can be further recorded on the HDD 7 and the removable medium 8 (video tape, video disk, etc.) and can be reproduced later.

  In addition, it connects to Internet servers and various peripheral devices (digital cameras, printers, keyboards, pointing devices, etc.) via modem 9 and peripheral device I / F10 (USB, IEEE1394, etc.), video data, audio data, other Code data communication can be performed.

  FIG. 2 is a block diagram showing the processing of the CPU 3 in the digital television receiving system embodying the present invention by function.

  The operation unit 21 is based on a viewer's operation using the remote controller 3 or other peripheral devices, and a channel selection unit 22, a channel selection reservation unit 22, an EPG processing unit 24, a recording reservation unit 25, a recording unit 27, a data control unit 28, a data broadcast It instructs the processing unit 29 and the Internet processing unit 30 to operate.

  The channel selection unit 22 switches channels based on instructions from the operation unit 21, channel selection reservation unit 23, EPG processing unit 24, and recording unit 25.

  The channel selection reservation unit 23 sets a reservation time in the timer based on instructions from the operation unit 21 and the EPG processing unit 24, and sends a channel selection instruction to the channel selection unit 22 when the reservation time comes.

  The EPG processing unit 24 displays an EPG (electronic program guide) screen based on the program information included in the broadcast data, and each of the channel selection unit 22, the channel selection reservation unit 23, and the video recording reservation unit 25 based on an instruction from the operation unit 21. Send instructions.

  The recording reservation unit 25 sets the reservation time in the timer based on the instructions of the operation unit 21 and the EPG processing unit 24, and when the reservation time comes, sends the channel selection instruction to the channel selection unit 22 and records the recording to the recording unit 27. Send instructions.

  The broadcast receiving unit 26 receives the broadcast of the channel designated by the channel selection unit 26 and sends the data to the data control unit 28. When recording, the received data is also sent to the recording unit 27.

  The recording unit 27 records the received data on a recording medium based on instructions from the operation unit 21 and the recording reservation unit 25. Further, various data (viewed channel history, etc.) are recorded on a recording medium based on an instruction from the data control unit 28. As these recording media, the memory 6, the HDD 7, the removable media 8, and other peripheral devices and servers on the Internet can be used. The recorded data is read as required by the operation unit 21 and other needs. Depending on the type of recording medium, it is possible to replace data, or to read out and combine a plurality of data recorded at a plurality of locations almost simultaneously.

  The data control unit 28 sends various data obtained by each processing unit to each processing unit as necessary.

  The data broadcast processing unit 29 is a data broadcast separated from the received data, subtitles, text super (subtitles are text linked to the main video, such as a Japanese translation of a Western movie, and the text super is like a breaking news Data relating to the text of the main story is interpreted, and based on instructions from the operation unit 21, video, audio, characters, and graphics are displayed.

  The Internet processing unit 30 interprets data obtained from the Internet via the modem 9, and displays video, audio, characters, and graphics based on instructions from the operation unit 21.

  The video / audio decoding unit 31 decodes the encoded moving image, still image, and audio.

  The character / graphic drawing unit 32 draws characters / graphics based on data such as data broadcasting, subtitles, character super, Internet, EPG.

  The video / audio signal output unit synthesizes a moving image, a still image, a character, and a figure, and outputs the synthesized image to the display I / F 4 as a video signal and outputs an audio signal.

  The above is the processing of a normal digital television reception system. In the present invention, additional information corresponding to a scene of a program broadcast in the past is acquired from the broadcast or the Internet by providing the additional information processing unit 34. When a scene corresponding to the additional information is viewed or recorded, the additional information can be recorded in the recording unit 27 or output to the display as video, audio, text, or a graphic.

  The basic operation of the additional information processing unit 34 will be described with reference to the flowcharts of FIGS.

  The flowchart of FIG. 3 is an operation that is performed regardless of whether or not the viewer is watching television at that time. That is, even when the viewer is sleeping or going out.

  In step S101, additional information is acquired. It is assumed that a code for identifying a corresponding scene, for example, a channel number and a broadcast date and time are added to the additional information. It is assumed that the additional information is transmitted in a data format such as a moving image, a still image, audio, data broadcasting, subtitles, character superimposing. A method for acquiring additional information will be described later.

  In step S102, the viewer views the scene corresponding to the additional information based on the viewing history recorded by the recording unit 27 (list of the viewed channel number and the viewing start date / time and viewing end date / time of the channel). Find out if it was. If so, the process proceeds to step S103. If not, the process proceeds to step S104.

  In step S103, the additional information is temporarily stored in the recording unit 27.

  In step S104, the viewer records a scene corresponding to the additional information based on the recording history (list of recorded channel number and recording start date / time and recording end date / time of the channel) recorded by the recording unit 27. Find out if it was. If recorded, the process proceeds to step S105, and if not recorded, the process ends.

  In step S105, the additional information is temporarily stored in the recording unit 27.

  In step S106, it is checked whether or not the recording medium for recording the additional information is ready for recording. When recording to the HDD 7 or when the target removable medium 8 is inserted, the process proceeds to step S108, and when the target removable medium 8 is not inserted, the process proceeds to step S107.

  In step S107, it is stored that the removable medium is waiting to be inserted, and the process ends once. This state is referred to in the operation of FIG. 4 described later.

  In step S108, the recording unit 27 adds the additional information in association with the scene of the recording data. There are two ways of appending. One is a method of overwriting old recording data with new recording data with additional data added, and the other is a method of storing additional data separately and synthesizing and outputting the old recording data and additional data each time playback is performed. It is. The latter method is highly flexible in that the output format of additional data can be changed based on the operation of the viewer during playback. For example, whether or not to display additional data can be switched at any time, and the size of characters for displaying additional data can be changed at any time. However, depending on the recording medium and recording format, it may be difficult to synthesize data during playback. In this case, the former method may be used.

  The flowchart in FIG. 4 represents an operation of outputting additional information when the viewer is watching television.

  In step S201, an additional information output request is generated. The additional information output request may be automatically generated when the power is turned on, or the viewer may explicitly perform an operation for requesting additional information output.

  In step S202, it is checked whether there is additional information temporarily stored in step S103 or S105 of FIG. If there is additional information, the process proceeds to step S203, and if not, the process ends.

  In step S203, the viewer views the scene corresponding to the additional information based on the viewing history recorded by the recording unit 27 (list of the viewed channel number and the viewing start date / time and viewing end date / time of the channel). Find out if it was. If the recorded scene has not been viewed yet, it is desirable not to inform the viewer of the content of the additional information until playback. This is because there is a possibility that the ending may be known only by looking at the additional information before looking at the main part of the sport or drama, and the interest of the main part may be distracted. If so, the process proceeds to step S204. If not, the process proceeds to step S205.

  In step S204, the additional information stored temporarily is read and output as video, audio, text, graphics, etc., thereby informing the viewer of the content of the additional information.

  In step S205, it is checked whether or not a removable medium is waiting to be inserted. If it is waiting for insertion, the process proceeds to step S206, and if not, the process ends.

  In step S206, a removable medium for recording additional information is inserted.

  In step S207, as with step S108 in FIG. 3, the recording unit 27 adds the additional information in association with the scene of the recording data.

  The additional information added in step S108 in FIG. 3 or step S207 in FIG. 4 is output in the scene when the recorded data is reproduced.

  A specific example of the additional information acquisition method will be described with reference to the flowchart of FIG.

  In step S301, the process waits until a preset EPG (electronic program guide) reception time is reached. While waiting, normal television viewing may be performed.

  In step S302, an EPG is received.

  In step S303, a program that broadcasts additional information is searched from EPG data. Here, in a specific program of data broadcasting, it is assumed that additional information for the program broadcast on that channel or a related channel is broadcast as data of data broadcasting.

  In step S304, if a data broadcast program for broadcasting additional information is not retrieved from the EPG, the process returns to step S301 and waits until the next EPG reception time. If a search is made, the process proceeds to step S305.

  In step S305, channel selection reservation is made for the data broadcast program by EPG.

  In step S306, the process waits until the channel selection reservation time is reached. While waiting, normal television viewing may be performed.

  In step S307, the data broadcast program is selected and additional information is received.

  Hereinafter, additional information is acquired as described in the flowchart of FIG.

  Further, as another specific example of the additional information acquisition method, additional information may be acquired by accessing a predetermined Web site via the modem 9. In the case of the specific example described above, it is necessary to wait until the time when a specific data broadcasting program for broadcasting additional information is broadcast. However, in the case of a Web site, additional information can be obtained as soon as it is updated.

  FIG. 6 is an example when there is a typo in the subtitle. (a) shows the subtitles and audio when it was first broadcast. (b) is a screen reproduced after acquiring and recording the additional information, and the additional information is displayed in a superimposed manner as a window. Instead of a window, a super character may be used.

  In this embodiment, there is an effect that the fact that the broadcast was first mistaken and the correction was made later remains as a record.

(Example 2)
FIG. 7 shows an example when there is a reading error in the sound. (a) shows the subtitles and audio when it was first broadcast. (b) is a screen reproduced after acquiring and recording the additional information, and the additional information is displayed as a superimposed character. A window may be used instead of the superimpose.

  In this embodiment, there is an effect that the fact that the broadcast was first mistaken and the correction was made later remains as a record.

(Example 3)
FIG. 8 is an example when there is a typo in the subtitle. (a) shows the subtitles and audio when it was first broadcast. (b) is a screen reproduced after acquiring and recording additional information, and is displayed with subtitles replaced by the additional information. Subtitles are transmitted as character code data instead of raster image data in digital television broadcasting, and can be recorded as character codes in digital recording. Therefore, subtitles can be replaced by rewriting the character code in the recorded data.

  Instead of subtitles, information included in the moving image (for example, if there is a typo in the character in the flip held by the announcer) should be replaced and displayed if the moving image is sent as additional information. Can do.

  In the present embodiment, there is an effect that it is possible to leave a record as if a correct broadcast was made from the beginning without disturbing the original video by annoying correction character super.

(Example 4)
FIG. 9 is an example when there is a mistake in reading the voice. (a) shows the subtitles and audio when it was first broadcast. (b) is a screen reproduced after acquiring and recording additional information, and the sound is replaced by the additional information.

  In this embodiment, there is an effect that it is possible to leave a record as if a correct broadcast was made from the beginning without disturbing the original sound with troublesome corrected sound.
