Abstract

PURPOSE:To achieve that a user and a producer can use the title apparatus conveniently by changing over the following by means of a switch: a means which records and replays a piece of character information in a region which is separate from a video-signal recording region; and a means which records and replays an original language for a foreign film and a Japanese-dubbed sound on the same tape. CONSTITUTION:Video signals and FM signals which have been input from a brightness-signal input terminal 40, a chroma-signal input terminal 41 and FM sound-signal input terminals 45, 46 are subjected respectively to a brightness-signal processing operation 42, a chroma-signal processing operation 43 and FM sound-signal processing operations 48, 49; after that, they are added to a pilot signal in an addition circuit 51; they are recorded in a video region on a magnetic tape via a REC amplifier 52 by means of video heads 53, 54. A superimposed information signal from a terminal 47 is recorded in a superimposed information region via an encoder 50, the REC amplifier 52 and the heads 53, 54. When a foreign-film software tape is produced, a Japanese-dubbed sound is input from the terminal 45, and an original- language sound is input from the terminal 46. Thereby, a two-language sound and a superimposed language can be recorded. Since the superimposed language is recorded in a region which is separate from that for the video signals, it is possible to control a superimposed output.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caption data recording / reproducing method and device for recording / reproducing caption data in a video signal recording / reproducing device (hereinafter referred to as VTR).

[0002]

2. Description of the Related Art Conventionally, a VTR Western video soft tape is a combination of (1) a foreign language audio (original language) and a subtitle super (a Japanese translation corresponding to the original language is superimposed on a video signal). (2) There are two types of tapes, which are obtained by dubbing the foreign language voice (original language) into Japanese, and the Western movie soft tape users selected these two types of tapes as needed. An example of a VTR that records a two-country audio signal is described in, for example, Japanese Patent Publication No. 3-18267.

[0003]

Therefore, the user is required to select one of these two types of tapes, and there is no degree of freedom in selecting the original language voice, subtitle superscript, and Japanese dubbed voice. There is a problem in that it is inconvenient for the user, and the creator of the Western movie software has to create and manage the above two types of tapes.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve these problems and provide a subtitle data recording / reproducing method and apparatus which are easy to use for both video software users and creators.

[0005]

In order to achieve the above object, in the present invention, as a first solution, a means for recording and reproducing the original language voice and the Japanese dubbed voice as FM modulated voice signals of two carriers each. And an identification signal recording means that indicates bilingual recording, a caption data (character data for performing subtitle superimposition) and an ID signal that indicates caption data, a video of an extended portion of the video signal recording track. Means for recording / reproducing in an area different from the signal recording area, caption data detecting means for detecting that the caption data is recorded, and means for superimposing captions on the reproduced video signal based on the caption data. Means for controlling the reproduced voice output of the original language voice and the Japanese dubbed voice and the operation of the superimposing means are provided.

As a second solution, means for recording / reproducing Japanese dubbed voice as an FM-modulated voice signal, means for recording / reproducing the original language voice as a PCM voice signal in an extended portion of the video signal recording track, and caption data The PCM
A means for recording / reproducing in an area between the audio recording area and the video signal recording area, an ID for generating a signal indicating that the data is caption data and a signal indicating that the Japanese dubbing audio is recorded as a PCM audio signal. Signal generating means,
Means for recording / reproducing this ID signal together with the caption data, caption data detecting means for detecting that the caption data is recorded, and means for superimposing captions on the reproduced video signal based on the caption data, Means are provided for controlling the reproduced voice output of the original language voice and the Japanese dubbed voice and the operation of the superimposing means.

[0007]

With the method and apparatus for recording and reproducing subtitle data according to the present invention, the original language voice, the Japanese dubbing voice, and the subtitle data can be recorded on the same tape when a VTR Western video soft tape is created. Further, since the caption data is recorded in an area different from the recording area of the video signal, it is possible to insert and delete the caption in the video signal during reproduction.
In addition, if you want to display subtitles during playback, the original language of the Western picture that requires subtitles is automatically output as an audio signal. It is possible to automatically output dubbing. Therefore, the creators of western-style video software create and manage two types of soft tapes, which are (1) a combination of original language audio and subtitles, and (2) a dubbing of the original language audio into Japanese audio, as in the past. Also, it becomes possible for users of Western-style video software to freely select the original language of Western movies or Japanese dubbing as an audio signal with the same soft tape, if necessary.
The usability is greatly improved for both video software users and creators.

First, the subtitle data signal recording area of the magnetic tape will be described with reference to FIG. As shown in FIG. 2, the caption data signal includes a video signal and an FM.
In a separate area between the video area for recording audio signals and the PCM area for recording PCM digital audio signals,
It is recorded as a digital signal. This is a video signal or P
Since the area is separate from the CM digital audio signal, new recording, rewriting, and erasing on the recorded tape can be freely performed.

In FIG. 1, a luminance signal input terminal 40, a chroma signal input terminal 41 and an FM audio signal input terminal 4 are provided.
The video signal and the FM audio signal inputted from 5, 46 are processed by the luminance signal processing circuit 42, the chroma signal processing circuit 43, and the FM audio signal processing circuits 48, 49, respectively, and then converted into a pilot signal by the adding circuit 51. Added and REC
After being amplified by the amplifier 52, it is recorded in the video area of the magnetic tape 1 by the video heads 53 and 54. On the other hand, the caption data signal input from the caption data signal input terminal 47 is converted into a digital signal by the data encoder 50 and then amplified by the REC amplifier 52, and the caption data shown in FIG. Recorded in the area.

Here, when a western-style video soft tape is created, a Japanese voiceover voice of western-style video is input from the FM voice signal input terminal 45 as the main voice of the FM voice signal, and F
From the M audio signal input terminal 46, the original language audio of a Western picture is input as a sub audio of the FM audio signal. As a result, it is possible to record the Japanese dubbing of Western movies and the bilingual sound of the original language on the same tape, and it is also possible to record subtitle data. Further, since the subtitle data is recorded in an area different from that of the video signal, output control (ON / OFF) of the subtitle super is possible.

Here, when a western-style soft tape is produced, the FM audio signal input terminals 45 and 46 are used as audio signals.
From, I input the Japanese dubbing of Western movies in stereo,
From the PCM audio signal input terminals 55 and 56, it is assumed that the original language of a Western picture is similarly input in stereo. As a result, when the PCM area of the tape is used, it is possible to record the Japanese dubbing of the Western picture and the bilingual sound of the original language in stereo, respectively, and it is also possible to record the subtitle data. In addition, since the subtitle data is recorded in an area separate from the video signal, output control of the subtitle super (ON / OFF)
Is possible. Here, the reason for recording the Japanese dubbing voice of the Western movie in the FM audio signal is that the Western movie soft tape recorded by this method is reproduced even in a VTR without a PCM audio signal processing circuit or subtitle data processing circuit. Since the Japanese dubbing is output as an audio signal, there is no particular problem as a western-style soft tape.

Next, an example of a reproducing apparatus for a magnetic tape recorded by the caption data recording method as shown in FIG. 1 or 3 will be described with reference to FIG. Further, FIG. 5 shows a flow chart of the output audio signal by the apparatus of FIG.

The signal reproduced by the video heads 2 and 3 from the magnetic tape 1 recorded as shown in FIG. 2 is amplified by the preamplifier 4, and then the video signal and the FM audio signal recorded in the video area are respectively obtained. , Luminance signal processing circuit 5, chroma signal processing circuit 6, FM audio signal processing BPF 1
3 and 14, and the pilot signal is supplied to the pilot signal processing circuit 7 and then output from the servo output terminal 8. On the other hand, P recorded in the PCM area
The CM audio signal and the caption data signal recorded in the caption data area are supplied to the EQ 25.

When the Western soft tape recorded by the method as shown in FIG. 1 or FIG. 3 is reproduced, the FM audio signal is supplied to the BPFs 13 and 14 and then demodulated by the FM audio signal demodulation circuits 15 and 16. Matrix circuit 18
Is supplied to. The bilingual system discrimination circuit 17 discriminates the bilingual system of the FM audio signal, and in the case of the bilingual system, the matrix circuit 18 outputs the F signal as an F signal.
The Western-language Japanese dubbing (main voice) is output to M1, and the original Western-language language (sub-voice) is output to FM2. When the system is not a bilingual system, the matrix circuit 18 outputs, as audio signals, the L channel of a Western picture to FM1 and the R channel of a Western picture to FM2.

On the other hand, the caption data signal recorded by the method shown in FIG. 1 or 3 and the PCM audio signal recorded by the method shown in FIG. 3 are code-equalized to remove transmission distortion by EQ25. And then supplied to the data strobe circuit 26. The data strobe circuit 26 regenerates the clock of the input signal, identifies the data of the input signal by the regenerated clock, and converts the data into a digital signal.

In the PCM audio signal processing circuit 27, the reproduced PCM digital audio signal is error-corrected and then data is decoded.
Channel, PCM2 is Western R channel, PCM
3 outputs "H" as a signal with PCM audio signal recording. On the other hand, when the PCM audio signal is not recorded, the PCM audio signal is recorded as a non-recorded signal.
L "is output, and the recording presence / absence signals of these PCM audio signals are output from the output terminal 38.

Similarly, in the data decoding circuit 28, data decoding is performed after error correction of the reproduced caption data signal, the decoded caption data signal is supplied to the character generation circuit 29, and a signal with caption data signal recording is also provided. "H" is output as. On the other hand, when the caption data signal is not recorded, "L" is output as a signal without recording the caption data signal. Further, the recording presence / absence signals of these subtitle data signals are output from the output terminal 39.

First, the superimposition of the caption data signal into the video signal by the switches 9 and 10 will be described.

In accordance with the caption data signal, the character generator circuit 29 outputs a luminance signal for indicating a caption, a chroma signal, and a key signal for controlling the switches 9 and 10 for superimposing the caption signal. To be done.
Further, the data decoder 28 always supplies "H" to the AND circuit 36 when the caption data signal is recorded. Here, when the subtitle output button 61 is pressed, "H" is input to the flip-flop 73, so the output Q of the flip-flop 73 becomes "H" and is supplied to the AND circuit 36. As a result, the output of the AND circuit 36 becomes "H". When the subtitle output button 61 is pressed again, the output Q of the flip-flop 73 becomes "L" and is supplied to the AND circuit 36. As a result, the output of the AND circuit 36 becomes "L". As described above, when the caption data signal is recorded, the output signal of the AND circuit 36 is switched to "H" / "L" by the caption output button 61. On the other hand, when the subtitle data signal is not recorded, the data decoder 28 always outputs "L" to the AND circuit 36.
, The output of the AND circuit 36 is always "L".

When the output of the AND circuit 36 is "H" (caption output is present), the key signal for controlling the switches 9 and 10 output from the character generator circuit 29 is directly output from the AND circuit 30. Therefore, the luminance signal indicating the caption is superimposed on the luminance signal supplied from the luminance signal processing circuit 5 by the switch 9, and then output from the luminance signal output terminal 11. Similarly, for the chroma signal indicating the subtitle, the switch 10 is used for the chroma signal processing circuit 6 as well.
It is superimposed on the chroma signal supplied from and then output from the chroma signal output terminal 12.
On the other hand, when the output of the AND circuit 36 is "L" (no caption output), the output of the AND circuit 30 is always "L", so the caption signal is not superimposed on the video signal by the switches 9 and 10.

Next, the audio signals output from the audio signal output terminals 23 and 24 will be described. Here, first, a case where a caption data signal is recorded will be described. In this case, "H" is always output from the output terminal 39 as a signal with a caption data signal recording. In addition, since "H" is input to the inverter circuit 72, AND
"L" is supplied to the circuit 71, and as a result, the output of the AND circuit 71 is always "L". As described above, when the caption data signal is recorded, the output signal of the OR circuit 70 is determined by the output signal of the AND circuit 37.

Here, when the PCM audio signal is recorded, the PCM 3 output from the PCM audio signal processing circuit 27 is always "H", so the subtitle output button 61 is pressed to change the output of the AND circuit 36 to "H". When switched to "(caption output is present)", the AND circuit 37 outputs "H". As a result, the output of the OR circuit 70 becomes "H" and the switches 21 and 22 are set to the PCM audio signal side, so that the PCM1 of the PCM audio signal is output from the audio signal output terminal 23.
Also, from the audio signal output terminal 24, P of the PCM audio signal
CM2 is output. When a Western movie soft tape is played, the original language of the Western movie is L in PCM1 in the PCM audio signal.
Since the channel and PCM2 are recorded in stereo with the R channel, the caption data signal and P
When the CM audio signal is recorded and the subtitle output button 61 is used to enable the subtitle output, the subtitle is superimposed in the video signal, and the original language audio is automatically output in stereo as an audio signal. To be done. (Fig. 5
A) On the other hand, when the PCM audio signal is recorded, if the output of the AND circuit 36 is switched to "L" by pressing the caption output button 61 (no caption output), the AND circuit 37 outputs "
L "is output. As a result, the output of the OR circuit 70 is"
Since the switch 21 and 22 are set to L ", the switches 21 and 22 are set to the FM audio signal side. Here, when the PCM audio signal is recorded, the outputs of the OR circuits 33 and 34 are set to" H ".
"H" is output from the ND circuits 31 and 32, as a result, the switches 19 and 20 are set to the "H" side, the FM2 of the FM audio signal is output from the audio signal output terminal 23, and the audio signal output terminal 24 is output. Outputs FM1 of the FM audio signal. Here, in the FM audio signal, a Japanese dubbing of a Western picture is recorded in stereo with the L channel in FM1 and the R channel in FM2. Therefore, when the caption data signal and the PCM audio signal are recorded and the caption output button 61 is used to disable the caption output, the caption is not superimposed in the video signal and the audio signal is automatically generated. The Japanese dubbing voice is output in stereo. (FIG. 5C) Next, the case where the PCM audio signal is not recorded will be described. In this case, PCM3 output from the PCM audio signal processing circuit 27 is always "L", and therefore the output of the AND circuit 37 is always "L". As a result, the output of the OR circuit 70 is always "L", and the switches 21 and 22 are
Is always on the FM audio signal side. When the subtitle output button 61 is pressed to switch the output of the AND circuit 36 to "H" (subtitle output is present), "H" is input to the OR circuit 33, but the OR circuit 34 is operated by the inverter circuit 35. "L" is input. Therefore, the output of the AND circuit 31 becomes "H", but the output of the AND circuit 32 becomes "L", and FM2 of the FM audio signal is output from the audio signal output terminals 23 and 24. When a Western soft tape is played back, if the PCM audio signal is not recorded, FM
In this case, in the audio signal, since the original language audio of the Western picture is recorded in the FM2 as the sub-audio of the bilingual system, the caption data signal is recorded but the PCM audio signal is not recorded. In this case, the subtitle output button 61
When the caption output is enabled by, the caption is superimposed in the video signal, and the original language sound is automatically output in monaural as an audio signal. (FIG. 5B) On the other hand, when the PCM audio signal is not recorded, the caption output button 61 is pressed and the output of the AND circuit 36 is set to "L".
When switched to (no subtitle output), the OR circuit 33 displays "
Although "L" is input, "H" is input to the OR circuit 34 by the inverter circuit 35. Therefore, the output of the AND circuit 31 becomes "L", but the output of the AND circuit 32 becomes "H". , F from the audio signal output terminals 23 and 24
FM1 of the M audio signal is output. When a Western picture soft tape is played back, if the PCM audio signal is not recorded, the FM audio signal shows that the Japanese dubbing sound of the Western picture is recorded as the main sound of the bilingual system in FM1. Therefore, as described above, when the caption data signal is recorded but the PCM audio signal is not recorded, if caption output is disabled by the caption output button 61, the caption is not superimposed in the video signal, Also, a Japanese dubbing voice is automatically output as a voice signal in monaural. (FIG. 5D) Finally, the case where no caption data signal is recorded will be described. In this case, since the output of the AND circuit 36 is always "L", the AND circuit 37 always outputs "L".
Is output. Further, since “L” is input to the inverter circuit 72, “H” is supplied to the AND circuit 71. Here, considering the case where a PCM voice signal is recorded, the output of the AND circuit 71 becomes "H", and as a result, the output of the OR circuit 70 also becomes "H", so that the switches 21 and 22 switch the PCM voice signal. It becomes the signal side. As described above, when the subtitle data signal is not recorded but the PCM audio signal is recorded, the PCM audio signal is automatically output in stereo from the audio signal output terminals 23 and 24.
(FIG. 5E) On the other hand, when the PCM audio signal is not recorded, A
The output of the ND circuit 71 becomes "L", and as a result, the output of the OR circuit 70 also becomes "L", so that the switches 21 and 22.
Is on the FM audio signal side. Further, AND circuits 31, 32
Output is always "L", switches 21 and 22
Is on the "L" side, and the audio signal output terminal 23 outputs the FM audio signal FM1 and the audio signal output terminal 24 outputs the FM audio signal FM2. As described above, when the subtitle data signal and the PCM audio signal are not recorded, the F signal is automatically output from the audio signal output terminals 23 and 24.
The M audio signal is output in stereo. (Fig. 5F) When considering a movie soft tape, the one in which the caption data signal is not recorded is usually a Japanese movie software or a Western movie software recorded by the conventional method, and in this case, the PCM voice signal is used as the voice signal. If recorded,
The PCM audio signal is output in stereo, but when the PCM audio signal is not recorded, the FM audio signal is output in stereo. Further, since the output of the AND circuit 36 is always "L", the switches 9 and 10 are always on the "L" side, and the superimposing of the caption into the video signal is not performed. As described above, it is possible to maintain compatibility with Japanese movie soft tapes or conventional Western movie soft tapes.

As described above, when the Western picture soft tape is reproduced by the caption data reproducing apparatus shown in FIG. 4, the caption output button 61 controls superimposing of the caption in the video signal. Further, the audio signal is automatically switched depending on the output signal of the flip-flop 73 switched by the caption output button 61, whether or not the PCM audio signal is recorded and whether or not the caption data signal is recorded. Here, the audio signal recorded on the magnetic tape is as shown in FIGS.
As shown in the subtitle data recording method of (3), the original language voice and the Japanese dubbing voice of the Western picture shall be recorded on a predetermined channel.

Next, with reference to FIG. 6, another example of the method for recording / reproducing subtitle data according to the present invention and the method for recording on a magnetic tape of the apparatus will be described. Reference numeral 59 is an identification signal input terminal.

At the time of creating a western-style video soft tape, from the identification signal input terminal 47, in which channel of the FM voice signal and the PCM voice signal, the original language voice of the western movie and the Japanese dubbed voice are recorded. Or not, and the data encoder 50 converts this into a digital signal together with the caption data signal. The PCM audio signal input from the PCM audio signal input terminals 55 and 56, the caption data signal input from the caption data input terminal 47, and the identification signal input from the identification signal input terminal 59 are added to the addition circuit 5
After being added in 8, and amplified by the REC amplifier 52, the PCM audio signal is recorded in the PCM area of the magnetic tape 1 and the caption data signal and the identification signal are recorded in the caption data area of the magnetic tape 1 by the video heads 53 and 54. It

At the time of reproduction, by processing this identification signal, it is possible to easily identify the audio signal recorded in each channel of the FM audio signal and the PCM audio signal. When creating, the original language of the Western movie and the Japanese dubbed voice are FM audio signal and P
It is possible to record in any channel of the CM audio signal.

The output signal from the PC is also controlled by the control signals C2 and C3.
It is switched to only PCM1 of the M audio signal, PCM2 of the PCM audio signal, or PCM1 and PCM2 of the PCM audio signal. Furthermore,
When caption output is present, the control signal C4 becomes "H", and the caption is superimposed in the video signal by the switches 9 and 10. However, when caption output is not performed, the control signal C4 is "
L ”, and the subtitles are not superimposed on the video signal.

Here, first, let us consider a case in which the output of the audio signal is automatically switched by the input signal from the audio switching signal input terminal 63 when the western picture soft tape is reproduced.

When the subtitle output button 61 is used to enable subtitle output, the control signal C4 becomes "H", and the control signals C1 and C are set in accordance with the output signal of the identification signal decoder 64.
2 and C3 also change, and the channel in which the original language voice of the Western picture is recorded is automatically output as the voice signal. In other words, when the PCM audio signal is recorded, the side where the original language audio is recorded in the FM audio signal or the PCM audio signal is output in stereo, but when the PCM audio signal is not recorded, it is bilingual. F recorded by the method
The side on which the original language voice of the M voice signal is recorded is output in monaural.

On the other hand, when the caption output button 61 is set to disable the caption output, the control signal C4 becomes "L" in the same manner.
Further, the control signals C1, C2, C3 also change in accordance with the output signal of the identification signal decoder 64, and the channel in which the Western-language Japanese dubbing voice of the Western picture is recorded is automatically output as the voice signal. That is, when the PCM audio signal is recorded, the side on which the Japanese dubbing audio is recorded by the FM audio signal or the PCM audio signal is output in stereo.
When the PCM audio signal is not recorded, the side on which the Japanese dubbing sound of the FM audio signal recorded in two languages is recorded is output in monaural.

As described above, the voice switching signal input terminal 63
When the output switching of the audio signal is automatically performed by the audio switching signal input from, the audio signal is automatically selected according to the output control (ON / OFF) of the subtitle superimposing by the subtitle output button 61.

Next, when reproducing the Western-style soft tape,
Consider a case where the output of the audio signal is manually switched by the audio switching signal input from the audio switching signal input terminal 63.

First, when the output is switched to output the original language sound of a Western picture, the control signals C1 and C of the output control circuit 68 are output.
By changing 2 and C3, the channel in which the original language voice of the Western picture is recorded is output as the voice signal. In other words, when the PCM audio signal is recorded, the side where the original language audio is recorded in the FM audio signal or the PCM audio signal is output in stereo, but when the PCM audio signal is not recorded, it is bilingual. The side in which the original language voice of the FM voice signal recorded in the method is recorded is output in monaural. Further, in this case, the control signal C is automatically
4 becomes "H", and the caption is superimposed on the video signal.

On the other hand, when switching to output the Western-language Japanese voiceover voice, similarly, by changing the control signals C1, C2 and C3 of the output control circuit 68, the Western-style Japanese voiceover voice is output as an audio signal. The recorded channel is output. That is, when the PCM voice signal is recorded, the side where the Japanese voiceover voice is recorded by the FM voice signal or the PCM voice signal is output in stereo, but when the PCM voice signal is not recorded, it is 2 The side on which the Japanese dubbing voice of the FM voice signal recorded in the Japanese language system is recorded is output in monaural. Also,
In this case, the control signal C4 automatically becomes "L", and the caption is not superimposed.

As described above, the voice switching signal input terminal 63
When the output of the audio signal is manually switched by the audio switching signal input from, the subtitle is automatically superimposed when the original language audio is selected as the audio signal of the Western picture, but the Japanese dubbing audio is When selected, subtitles are not superimposed.

Finally, consider a case where data of several languages other than Japanese is recorded in the caption data area as the caption data signal. In this case, the caption switching signal input terminal 62
By switching the output signal of the character generation circuit 67 with the subtitle switching signal input from, it is possible to switch the subtitles of several languages in the video signal and superimpose.

As described above, in the caption data recording method shown in FIG. 6 and the caption data reproducing device shown in FIG. 7, the audio signal is transmitted by the identification signal in any of a total of four channels of the FM audio signal and the PCM audio signal. Can be recorded and played. Therefore, the audio signals in four different languages are recorded in each channel in monaural, the data in four languages is also recorded in the caption data signal, and the language of the audio signals recorded in each channel is recorded in the identification signal. By recording the types, it is possible to create Western-style soft tapes in four languages with the same tape. Also, by recording other than Japanese as the subtitle data signal to support several languages, and by recording the original language voice as the audio signal in four channels, it is possible to reproduce a multi-sound full of presence. Furthermore, the TV audio output is the Japanese dubbing audio of Western movies for children, the headphone output is the original language audio of Western movies for adults, and by displaying subtitles on the screen, both children and adults can simultaneously use Western movie software. You can also enjoy.

Finally, a karaoke system using the subtitle data recording / reproducing method and device according to the present invention will be described. In this case, by recording the lyrics as the caption data signal and the melody of the song as the audio signal, the karaoke soft tape can be easily created. At this time, it is possible to record the melody of the song and the singing voice of a professional in stereo on two channels of the audio signal, and record only the melody of the song on the other two channels in stereo. Furthermore, by recording another song in stereo for each two channels of the audio signal, or by recording another song in monaural in each of the four channels and recording lyrics for two channels or four channels as the caption data signal. It is also possible to record many songs on the same tape.

[0046]

As described above, in the caption data recording / reproducing method and device according to the present invention, when a VTR foreign movie soft tape is created, the original language voice, the Japanese dubbing voice, and the subtitle data signal are recorded on the same tape. Can be recorded in. Moreover, since the caption data signal is recorded in an area different from the recording area of the video signal, it is possible to superimpose the caption in the video signal. As a result, if the same tape is used to display subtitles during playback, the original language audio of the Western movie that requires subtitles is automatically output as an audio signal, while if subtitles are not displayed, subtitles are not required. It will be possible to automatically output the Japanese dubbed voice of Western movies. Therefore, the creators of western-style video software create and manage two types of soft tapes, which are (1) a combination of original language audio and subtitles, and (2) a dubbing of the original language audio into Japanese audio, as in the past. Also, it becomes possible for users of Western-style video software to select the original language of Western movies or Japanese dubbing as the audio signal as needed using the same soft tape. Both are greatly improved in usability. Furthermore, by recording data in several countries afterwards as a caption data signal, it is possible to create a soft tape compatible with several countries after the same tape.
