Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to dialogue character display devices for use with playback systems for recording media such as video and audio recording media, such as videotapes and videodiscs. In particular, the present invention
A dialogue character display device that displays the characters of a translated word on a display in synchronization with the audio of the original language, that is, the dialogue of the original language, during playback without affecting the video and audio signals already recorded on a recording medium. Regarding.

BACKGROUND OF THE INVENTION With the recent development of video information systems, video tapes or video discs recording programs such as various shows and feature films can be easily obtained in the general market, and it is also possible to record on these recording media. The information provided is not limited to domestic programs, but covers a wide range of programs from around the world. However, one obstacle to watching foreign programs is the difference in language used. Therefore, in order to solve this problem, when creating a recording medium for foreigners under the Video Recording Act, a new translated version is created by directly changing the video signal or audio signal of the original recording medium. Something is being done.

A method of producing such a translated version includes, for example, when making changes to the video, in order to display the translated dialogue characters on the screen in synchronization with the original language dialogue, characters indicating the translated word are added to the original version of the video. There is a Sue ξ-impose method that adds a background signal and the original language to make it appear as if the original language dialogue is being spoken in the translated language. Separate the dialogue signal and
There is a dubbing method in which this dialogue signal is replaced with a dialogue signal of the translated word, and the dialogue is converted into the translated word's dialogue.

However, as mentioned above in the conventional method of producing a translated version, when producing a translated version that corresponds to many languages, in order to make direct changes to the video or audio itself recorded on the recording medium of the original version. must prepare a large number of translated original versions. On the other hand, for viewers who have obtained a translation board, for example, even if they wish to enjoy the program in its original language, the characters in the translated language or the dialogue in the translated language will always be part of the video in the translated recording medium. Alternatively, it may be completely incorporated as part of the audio and cannot be changed by the viewer's intention. Therefore, conventional translated versions cannot adequately meet the needs of diversified audiences.

Purpose of the Invention In view of the above-mentioned current situation, the present invention has been developed to allow the viewer to perform simple operations during playback to reproduce dialogue in the original language without changing the information recorded on the original video/audio recording medium. It is an object of the present invention to provide a dialogue character display device capable of displaying characters of translated words on a display in synchronization.

Specifically, the present invention provides an original video/audio recording medium that does not directly change the recorded video and audio, but instead affects the empty channel that does not affect the audio of the audio signal or the screen of the video signal. On the other hand, the translated version dialogue character recording medium and its display position on the display are recorded separately from the original version audiovisual recording medium and its playback device. A video/audio system that is equipped with a playback device and detects the markings on the video/audio recording medium during playback of the original version to synchronously play back the translated version's dialogue text recording medium and display the translated dialogue characters on the display. It is an object of the present invention to provide a novel dialogue character display device for use with a recording medium playback system.

3. Detailed description of the invention The invention will be explained in detail below with reference to illustrated embodiments.

FIG. 1 is an overall block diagram of an original video/audio recording medium reproduction system 1o equipped with a dialogue character display device of the present invention.

Videotape cassette - videotape 12A or videodisc 12B played by an original playback device such as player 11A or videodisc player 11B
The audio and video signals of the original audiovisual recording medium are input to input terminals A and 13 of the dialogue character display device 16, respectively.

Markings recorded in advance on empty channels of the audio signal or blanking portions of the video signal of the original video/audio recording medium are detected during playback and input to the input terminal C of the device 16 as a character display control signal.

On a translated dialogue character recording medium such as a magnetic tape 14A or a floppy disk 14B, dialogue characters and position signals to be displayed on a display 15 such as a television receiver are prerecorded. It is played by a translation playback device, such as a magnetic tape cassette player 16A or a floppy disk player 16B, under the control of the character display device 16.

The dialogue character display device 13 supplies audio signals to the display 15 through an input terminal and an output terminal, and video signals through an input terminal B and an output terminal E, respectively.
To enable viewing of video and audio using the same method as before. Furthermore, when the dialogue character display device 13 receives a character display control device based on marking detection at the input terminal C, it gives a reproduction control signal to the translated version reproduction device 16A from the output terminal G, thereby controlling the reproduced dialogue character signal. The input terminal 1i' receives the signal, converts the signal appropriately for the display 15, and outputs a character display signal from the output terminal 1-1.

As a result, on the display 75, the audio and video of the original version are played back, and at the same time, the dialogue characters 16 of the translated language are displayed in synchronization with the dialogue of the original language.

FIGS. 2, 3, and 4 show specific block circuit diagrams of the speech character display device 16 of the present invention shown in FIG. 1, and each embodiment will be described below.

Figure 2 shows the original start/stop signal and dialogue in/out signal as markings on empty channels that do not affect the sound of the audio signal of the original video/audio recording medium or blanking areas that do not affect the screen of the video signal. A block circuit diagram of a dialogue character display device in the case of pre-recording is shown. Simultaneously with the start of reproduction of the original, the original version start signal aligns the start position of the original video/audio recording medium 12A with the start position of the translated version dialogue character recording medium 14A, thereby enabling reproduction of the latter recording medium. The original stop signal is issued at the same time as the original video/audio recording medium 12A is completed.
All reproduction operations of the translated version dialogue character recording medium 14A are stopped. The dialogue in signal determines the timing of inserting dialogue characters during reproduction of the original version, and the dialogue out signal determines the timing of erasing dialogue characters during reproduction of the original version, and at the same time, the dialogue character recording medium 14A of the translated version is pulled out. Continuing (reproduction drunkenness stand 1st 7-, -, "Hikiotsu's pickled drink ten-chilled bar weight opening #
The signal is then supplied as a character display control signal to the input terminal C of the dialogue character display device.

As shown in FIG.

The display control unit 20 superimposes the dialogue character signal read from the storage unit 21 on the video signal inputted from the original video/audio recording medium via the input terminal B and the buffer amplifier 24, and displays the dialogue on the screen on the display. A video signal and a character display signal are supplied to output terminals E and I-I, respectively, in order to display dialogue characters in superimposition or in synchronization with the screen on the display. Therefore, the display control unit 20 responds to the dialogue in signal inputted to the playback control unit 26 and the horizontal and vertical synchronization signals of the video signal to generate the dialogue character signal stored in the storage unit 21, that is, the characters and positions. The signal is read out using a reading command signal, and the dialogue characters are superimposed on the screen on the display or the dialogue characters are displayed in synchronization with the screen on the display,
Furthermore, it operates to display the dialogue characters in color as necessary, and also erases the dialogue character signals stored in the storage unit 21 in response to the dialogue out signal and the horizontal and vertical synchronization signals, and at the same time, displays the dialogue characters on the display. Operates to erase dialogue characters.

Word processing] W interface 22 is a playback control unit 26
In response to the output reproduction control signal, the dialogue character signal reproduced from the translated dialogue character recording medium is input via the input terminal F and the buffer amplifier 25, and this signal can be processed by the display control unit 20. The data is converted into an appropriate format and arrangement and supplied to the storage section 21 in response to a synchronization control signal from the reproduction control section 23.

The storage unit 21 stores the dialogue character signal from the word processing interface 22 for each group of dialogue characters displayed as appropriate on the display, and avoids overlapping writing and reading operations when the frequency of dialogue increases. In order to
It is equipped with multiple storage devices as needed. Storage section 21
If the dialogue character signal is not stored in the storage unit 21,
A dialogue start signal is given to the playback control unit 23 for the translated version.

The dialogue character signal of the storage unit 210 is in synchronization with the horizontal and vertical synchronization signals of the video signal input to the display control unit 20 in response to the dialogue in signal input to the playback control unit 26 via the input terminal C. is repeatedly read out under similar synchronized conditions in response to a speech out signal. When the dialogue character signal is erased from the storage section 21 in this manner, the storage section 21 provides a new dialogue start signal to the reproduction control section 23 as described above. The storage section 21 also provides a dialogue stop signal to the playback control section 23 in order to stop the operation of the translated version reproducing device when the storage device becomes full with dialogue character signals.

The playback control unit 26 inputs a character display control signal from the original video/audio recording medium via the input terminal C, outputs a synchronization control signal as appropriate, and controls the display control unit 20, storage unit 21, and word display as described above. It controls the processing interface 22 and inputs a dialogue start/stop signal from the storage unit 21 to control reproduction of the translated version dialogue character recording medium.

The buffer amplifiers 24 and 25 are provided to maintain appropriate voltage levels and signal-to-noise ratios of the signals input thereto, and the dialogue display switch 26 allows the viewer to change dialogue characters as necessary. It is provided so that display or removal can be selected.

The overall operation of the dialogue character display device shown in FIG. 2 will be described below.

When the reproduction of the original video/audio recording medium is started, the audio signal is transmitted through the input terminal A and the output terminal, and the video signal is transmitted through the input terminal B, the buffer amplifier 24, the display control section 20, and the output terminal E. Each is supplied to a display.

At the same time, when the original version start signal is input to the playback control unit 26 via the input terminal C, the playback control unit matches the start position of the original video and audio recording medium with the start position of the translated version dialogue character recording medium. , outputs a dialogue start signal through the output terminal G in order to start playing back the translated version of the dialogue character recording medium. The dialogue character signal reproduced in response to the dialogue start signal is stored in the storage section 21 via the input terminal F, the buffer amplifier 25, and the word processing interface 22. If the storage device of the storage unit 21 becomes full of dialogue character signals, the storage unit 21 outputs a dialogue stop signal, and this signal is given to the translated version reproduction device via the reproduction control unit 26 and output terminal q, and the reproduction is stopped. Stop the operation. When a dialogue character signal exists in the storage unit 21 and a dialogue in signal is input to the playback control unit 26, the storage unit 21
The dialogue character signal is read out, and the display control unit 20 supplies it to the display via the character display signal and I output terminal I]. As a result, the translated version of the dialogue characters is displayed on the display in synchronization with the original version of the video and dialogue. Next, when the dialogue out signal is input to the playback control section 23, the dialogue character signal from the storage section 210 is erased, the output of the character display signal from the display control section 20 is stopped, and the dialogue characters on the display are erased. At the same time, the storage section 21 outputs a dialogue start signal, and this signal is outputted via the reproduction control section 26 and the output terminal G to start the next reproduction of the translated version of the dialogue character recording medium.

The above operations are repeated until the reproduction of the original video/audio recording medium is completed. When the reproduction of the original video/audio recording medium is completed, an original version stop signal is input to the reproduction control section 23, which causes the reproduction control section 26 to operate the translated version reproduction device,
All operations of the display control section 20, storage section 21, and word processing interface 22 are stopped.

Generally, a video disk has a track number signal recorded thereon in a location that does not affect the video signal and audio signal, and some video cassette tapes also have a track number signal recorded thereon. On the other hand, even if a track number signal is not recorded on a video/audio recording medium, it is possible to count the number of tracks (or fields) during playback and to sequentially detect each line that is played back using signal detection additional technology. A line number signal can be easily added.

These track number signals or dialogue number signals can be used as markings for displaying dialogue characters.

FIG. 3 shows a block circuit diagram of a dialogue character display device in which a track number signal or a dialogue number signal recorded on an original video/audio recording medium is used as a marking.

In addition to dialogue character signals, that is, character and position signals, the translated version of the dialogue character recording medium contains a track (or dialogue) that is compared and verified in synchronization with the track (or dialogue) number signal of the original video/audio recording medium. ) The number signal is pre-recorded.

As shown in FIG. 6, the dialogue character display device height, display control section 20', storage section 21', word processing interface 22', playback control section 23', buffer amplifier 24'
and 25', and a dialogue display switch 26'.
These components accomplish similar functions to the components shown in FIG.

The dialogue character display device shown in FIG. 6 further includes a signal separation encoder 60, a track (or dialogue) number encoder 61, a track (or dialogue) number storage section 62, and a comparison/discrimination section 66.

The signal separation encoder 30 separates only the track number signal from the dialogue character signal and track number signal inputted to the buffer amplifier 25' via the input terminal F from the translated dialogue character recording medium, and uses this signal for comparison as described below. Code for verification.

The track number storage unit 32 temporarily stores the track number signal output from the signal separation encoder 60 for comparison with the track (or dialogue) number signal of the original video and audio recording medium.

The track number signal of the translated version of the dialogue character recording medium stored in this storage unit is
Cleared in preparation for the next comparison.

The track number encoder 31 inputs the track number signal from the original video/audio recording medium through the input terminal C, and compares and verifies the track number signal from the translated version dialogue character recording medium stored in the storage unit 32. code for.

The comparison/discrimination unit 66 compares the track number signal from the original video/audio recording medium outputted from the track number encoder 61 with the track number signal from the translated dialogue character recording medium outputted from the track number storage unit 62. Comparisons are made sequentially, and in response to a match in the comparisons, a character display control signal as described in connection with FIG. 2 is supplied to the reproduction control section 26'.

The overall operation of the dialogue character display device shown in FIG. 6 will be described below.

When playback of the original video/audio recording medium is started, the audio signal is sent to the input terminal A and the output terminal, and the video signal is sent to the input terminal B, the buffer amplifier 24', and the display controller 20'.
, are supplied to the display via output terminals E, respectively. At the same time, input terminal C is input from the original video/audio recording medium.
A first track number signal is input to the track number encoder 31 via the track number encoder 31 . On the other hand, the first track number signal from the translated version of the dialogue character recording medium is sent to the track number storage section 62 via the input terminal F, the buffer amplifier 25', and the signal separation encoder 60.
is memorized. When the comparison/discrimination unit 63 determines whether the first track number signal from the original video/audio recording medium matches the first track number signal from the translated dialogue character recording medium, the comparison/discrimination unit 63 detects the original version start signal. camera to the playback control section 26'. The reproduction control unit 23' outputs a dialogue start signal via the output terminal G in order to start reproduction of the translated version of the dialogue character recording medium. The dialogue character signal and the second track number signal reproduced in response to the dialogue start signal are input to the input terminal F and the buffer amplifier 25'. The dialogue character signal outputted from the buffer amplifier 25' is stored in the storage section 21' via the food processing interface 22', and at the same time, the second track number signal separated by the signal separation encoder 60 is transmitted to the next The track number is stored in the track number storage section 62 in preparation for comparison and verification.

As mentioned above, if the storage device of the storage section 21' becomes full with dialogue character signals, the storage section 21' outputs a dialogue stop signal, and this signal is sent to the playback control section 26'.

A signal is applied to the translated version playback device via the output terminal G to stop its playback operation. When the dialogue character signal exists in the storage unit 21, the second track number signal of the original is input to the encoder 61 via the input terminal C, and the comparison/discrimination unit 33 detects the second track number signal in the track number storage unit 32. When it is determined that there is a match with the track number signal, this comparison and determination section outputs a speech-in signal. When the dialogue in signal is input to the playback control section 23', the dialogue character signal in the storage section 21' is
The display control section 20' supplies it to the display via the output terminal I-I as a character display signal.

As a result, the translated version of the dialogue characters is displayed on the display in synchronization with the original version of the video and dialogue.

Next, the comparison/discrimination unit 6 includes, for example, a timer circuit (not shown) having a preset time limit corresponding to the display period of a group of dialogue characters, and outputs a dialogue out signal after a certain display period has elapsed. Output.

When the dialogue out signal is input to the playback control section 26', the dialogue character signal in the storage section 21' is erased and the character display signal from the display control section 20' is replaced, as described above with reference to FIG. output is stopped and the dialogue characters on the display are erased. At the same time, the storage section 21' outputs a dialogue start signal, and this signal is outputted via the reproduction control section 26' and the output terminal q to start the next reproduction of the translated version of the dialogue character recording medium.

Although it has been explained that the dialogue out signal is output from the comparing and determining section 66, the playback control section 26' outputs an appropriate value to the storage section 21' after H [a certain period of time has elapsed from the manual output of the dialogue in signal. An erase signal may also be output. The above operations are repeated until the reproduction of the original video/audio recording medium is completed. The last track number signal of the original video/audio recording medium is manually input to the echo 61,
When it is determined that the track number signal matches the last track number signal of the translated dialogue character recording medium stored in the track number storage section 62, this comparison and determination section outputs a playback stop signal,
As a result, the playback control section 26' stops all operations of the translated version playback device, display control section 20', storage section 21', word processing interface 22', etc.

When used, Figure 4 is obtained by voice recognition of the original language dialogue when the original version is played back, without making any changes to the video and audio signals of the original video/audio recording medium, and without adding markings. 1 is a block circuit diagram of a speech character display device in which a voice recognition code signal is used in place of marking.

The configuration of the dialogue character display device in Figure 4 is basically the same as that in Figure 6, and in Figure 3, the track (or dialogue) number signal recorded on the original video and audio recording medium is In this way, a voice recognition code signal obtained directly from the reproduced voice is used, while a translated version of the dialogue text recording medium has a recorded track (or dialogue) number signal instead of a recorded track (or dialogue) number signal.
A speech recognition code signal for recognizing the reproduction of speech characters corresponding to the speech of the original version is recorded in advance.

Therefore, as is clear from a comparison with the dialogue character display device of FIG. 6, in the dialogue character display device of FIG.
Separates only the dialogue recognition signal from the dialogue character signal (character and position signal) and dialogue recognition signal that are input to the buffer amplifier 25'' through the buffer amplifier 25'', and encodes this signal for comparison with the voice recognition code signal. .

The speech recognition code storage unit 42 includes a signal separation encoder 40
temporarily stores the dialogue recognition code signal output from the
This stored signal is cleared in preparation for the next comparison when the aforementioned comparison match results in a match.

The voice recognition encoder 41 inputs the voice signal input from the original video/audio recording medium through the input terminal A via the buffer amplifier 44, recognizes and encodes the voice, and outputs a voice recognition code signal. . Specifically, this encoding can be performed, for example, by converting the data into numerical values using A/D conversion such as pulse code modulation (PCM'). However, when generating the voice recognition code signal, it is necessary to sample the voice signal during a period in which the comparing and determining section 46 will not make a misjudgment;
Since it is necessary to compensate for display delays and increase storage capacity, the sampler period must be chosen to an appropriate value.

The comparison/determination unit 46 sequentially compares and matches the speech recognition code signal of the original version outputted from the speech recognition encoder 41 and the dialogue recognition code signal of the translation board outputted from the dialogue recognition code storage unit 42, and determines the result of this comparison and verification. In response to a match, the second
A character display control signal as described in connection with the figure is supplied to the reproduction control section 26''.

The overall operation of the dialogue character display device of FIG. 4 is as follows in the corresponding explanation of FIG. 6, by simply replacing the track (or dialogue) number signal of the original video and audio recording medium with a voice recognition code signal.
By replacing the track (speech) number signal of the dialogue character recording medium of the translation board with a dialogue recognition code signal, the explanation can be made in exactly the same way, and therefore a detailed explanation will be omitted. In the dialogue character display device shown in FIG. 4, the comparison and discrimination section 46 determines whether the playback control section 26''
The original plate start signal is configured to be supplied to the original plate start signal.
