Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a magnetic recording / reproducing apparatus for recording / reproducing video / audio information and translated character information on a common magnetic tape. The present invention is particularly suitable as a digital VTR. It is also suitable for providing bilingual video sources.

[0002]

2. Description of the Related Art Content, which is the content of a video source, is:
The main elements are video information and audio information related to the video information. The audio information is generally audio information in the native language, but in a situation where internationalization is progressing in recent years, foreign language information on the audio information of the content is required. This is because in the processing of the human brain, video information has no language barrier, whereas audio information has a language barrier. When visualizing any kind of video, it can be understood equally no matter who is in any country.
But when it comes to hearing processing of language,
It is difficult or difficult to understand the language you are not learning. In other words, while video is information that can be understood intuitively, language is information that cannot be understood unless it passes through a filter called a learned language, and is more advanced and more artificial information. Under such circumstances, as is well known, translation and interpreting are generally required.

[0003] Therefore, it is also well known that superimposed subtitles translated into the language required by the user are superimposed on the content and projected, and sound of the translated language is output to a speaker. is there.

[0004] Here, it is assumed that the translated voice is not considered, and that a subtitle superimposed as a translated character display is mainly considered. Character information as subtitles, which is obtained by translating audio information recorded on the same video tape in association with video information into another language, is referred to as “translated character information”.

[0005] The recent wave of internationalization is remarkable. That is, there are many opportunities to view video sources in which various races and ethnic groups are various other foreign cultures. However, when superimposing subtitles on one video source and recording them on the same video tape,
At present, only one type of language subtitle is superimposed.

In other words, when recording translated character information together with video information and audio information on a common magnetic tape, conventionally, in advance editing work, translated character information of a language in demand is prepared, and After mixing the translated text information with the video information of the information and audio information to produce a composite video signal with superimposed subtitles, record the composite video signal with superimposed subtitles on one video tape, and broadcast the video tape. Used for storage or sale. In this video tape, the video information is covered by the subtitle super information, and the original originality of the video information is lost. In order to ensure the originality of the video information, another video tape that records the video information without covering the subtitle super information is stored.

[0007] By the way, regarding the title of the content, there has been proposed a device in which the title is superimposed and displayed on a monitor display at the time of reproduction by a consumer magnetic recording / reproducing apparatus.
This is to display a video with a title without dubbing editing. For this purpose, a time code and a memory are used. For example, necessary title data is stored in a memory in advance. It is necessary to determine at what timing title data is read when a video tape is reproduced. Therefore, a time code value considered at this timing is set in advance. When playing a video tape, the time code output together with the playback video signal is extracted and checked, and it is determined whether the extracted time code matches a preset time code value. Then, the title data corresponding to the time code value is read from the memory, a title video signal is generated based on the read title data, and the title video signal is superimposed on the reproduced video signal and displayed. (See, for example, JP-A-64-79990).

[0008] In the above case, there is a problem that a title for another video tape may be superimposed upon reproduction of a certain video tape. The time code is generally written sequentially from the beginning of the video tape, because the same time code value exists in a plurality of video tapes. Japanese Unexamined Patent Publication No. 6-141278 proposes to solve such a problem. It uses date / time in addition to timecode for matching, and there is usually a possibility that the timecode / date / time of multiple videotapes will match as the timing to superimpose the title. It takes advantage of the fact that it is extremely low. When an on-air video signal is taken in from an input terminal and recorded on a video tape, time code / date / time data is added as an information signal and recorded on the video tape. The date / time data is data at the time of recording the content, and there is almost no possibility that the date / time data is the same between a plurality of video tapes in the same magnetic recording / reproducing apparatus.

The magnetic recording / reproducing apparatus disclosed in JP-A-6-141278 is provided with a title generating circuit. The title generation circuit has a storage unit for storing data of a plurality of title signals. The user operates the title superimpose key and the title selection key on the operation unit to select a desired title. Then, a corresponding title number is generated, and a desired title signal is generated to access the title generation circuit with the title number, and is output from the video signal output terminal through the superimpose circuit. By displaying the video on the monitor display, the user confirms the selected title. This stage is only for title confirmation. Not yet relevant for videotape. By the operation of determination, the selected title number is stored in the memory.

Next, a video tape which has been recorded with time code / date / time data added at the time of recording is reproduced. The reproduced video is displayed on a monitor display. While watching the playback video, determine the timing of the scene in which the title is to be inserted, and operate the superimpose timing key on the operation unit. As a result, the time code, date,
The time data and the previously selected title number are stored in the memory in association with each other. Thus, the setting of one title is completed. The user sets another title number and timing to be superimposed. Similar processing is performed on other video tapes. In this way, a plurality of sets of time code / date / time data and title number data for a plurality of video tapes are stored in the memory. The above is the processing for associating the data (time code / date / time data) on the video tape with the data (title number) in the memory of the VCR.

[0011] When performing automatic superimposition when any of the video tapes is set on the deck for reproduction, the user designates an automatic superimpose mode in the operation section and gives a reproduction command. Then
The memory is searched based on the time code, date, and time data read from the video tape, and when there is a corresponding one, the corresponding title number is read from the memory at that timing and transmitted to the title generating circuit, A title signal corresponding to the title number is generated and sent to the superimpose circuit. In the superimpose circuit, a title signal is superimposed on a video signal reproduced from a video tape and displayed on a monitor display.

In the prior art disclosed in Japanese Patent Application Laid-Open No. 6-141278, the title signal is not recorded on a video tape, but the title number is stored in a memory on the deck outside the video tape, and the title signal is recorded on the video tape. Only records time code, date and time data. The time code / date / time data is associated with the title number in the memory.

[0013]

Problems to be Solved by the Invention Japanese Patent Laid-Open No. 6-14127
In the magnetic recording / reproducing apparatus disclosed in Japanese Patent Application Publication No. 8 (1996), the originality of the original video information can be secured because the title signal need not be recorded on the video tape. Type title data must be stored, and the storage capacity becomes large. Also, the memory is searched based on the time code, date, and time data extracted from the reproduced video signal, and However, the configuration is considerably complicated.

Further, since the association between the time code / date / time data and the title number is performed outside the video tape, that is, in the memory of the deck, the association is not completed within the video tape. Therefore, even if the same video tape is used, if the magnetic recording / reproducing device is different, there is no corresponding reference data in the memory of the other magnetic recording / reproducing device, so that the desired title cannot be superimposed. It is. In order to realize this, in a plurality of magnetic recording / reproducing devices, the relationship between information signals such as date and time to be recorded on a video tape and the title and the title code standard are strictly determined, and all magnetic recording / reproducing devices are required It will be required to follow the standard.

Furthermore, the above-mentioned Japanese Patent Application Laid-Open No. Hei 6-141278 merely adds a title, and it is extremely difficult to apply it to a subtitle superimposed by translating a language which is the substantial content of the content.

At present, it is almost impossible to apply the technique of the above-mentioned publication to the technique for ensuring the selectivity of the caption superimposition of various languages in the state where the caption superimposition of at most one kind of language is superimposed. It can be said that.

The present invention has been made in order to solve the above-described problems, and secures originality of video information and audio information on a common magnetic tape, and
When outputting translated character information in multiple languages as superimposed video information added to the original video information, it is to be realized under the simplest possible configuration, and at the same time, to stimulate demand for magnetic tape (video tape). The purpose is.

[0018]

The magnetic recording / reproducing apparatus of the present invention for solving the above-mentioned problems has the following requirements. The original video / audio information and a plurality of character information are recorded in different areas on a magnetic tape.
Then, when reproducing the magnetic tape, character information is selected based on a character information selection signal set in advance,
The text information is superimposed on the video information and output. By doing so, according to the present invention, the video information / audio information and a plurality of character information are recorded coexistently on a common magnetic tape while securing the originality of the original video information / audio information. In reproducing the magnetic tape, an output video signal in a state where the selected character information is added to the video information can be obtained. Nevertheless, all the information necessary to realize the above is recorded on a magnetic tape in a self-contained manner, so that the load on the device side is reduced,
The configuration is also simplified. In particular, since desired character information can be selected from a plurality of character information instead of just one, there is the convenience that the user side can realize subtitle supermarket etc. by changing the language etc. conditions, and the manufacturer side has a common There is an advantage that a plurality of subtitles can be recorded on a magnetic tape and demand can be stimulated. For example, in a library, while displaying the original video of the content on the monitor display, the user can select and explain the video content in a subtitle supermarket in the user's language, or monitor display installed in each seat of the aircraft There is a development in which, while a movie is being displayed, the subtitles of the movie are set to the subtitles in the language used by the user according to the user's selection.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be generally described.

According to a first aspect of the present invention, there is provided a magnetic recording / reproducing apparatus which associates video information with audio information and records the information on a magnetic tape, and separately stores a plurality of character information on the audio information on the magnetic tape and the video information / audio. The information is recorded in an area different from the information, the video information, the audio information, and a plurality of character information are separated from a reproduction signal when reproducing the magnetic tape, and character information is selected based on a set character information selection signal. , Wherein the selected character information is superimposed on the separated video information and output. The operation of the first invention is as follows.

The video information / audio information and the character information are recorded on a common magnetic tape, and the recording mode is recorded in a state where they are clearly separated into different areas. Although both video and audio information and text information are recorded coexistently on the tape, the video and audio information is independent of the text information in the recording mode and is not subject to deformation. Since the state is maintained, it is possible to ensure the originality of the video information / audio information. When reproducing the magnetic tape, the reproduced signal from the magnetic tape is not used as it is as the output video signal, but the video information is individually cut out as the video information and the audio information as the audio information according to the difference in the identification information. In addition, since the character information is cut out independently as character information, and the video information and the character information are superimposed to form an output video signal, it is possible to output a video signal with the text information added to the video information. It is possible.
That is, it is possible to output a video signal in which text information is added to video information while securing the originality of video information and audio information, and to ensure that both properties (originalness and text information addition) are consistent. In addition, it is possible to realize the present invention not on a separate magnetic tape but on a common magnetic tape. In other words, video information
Since both voice information and character information are recorded on a common magnetic tape, in order to combine the two properties (the originality and the addition of character information), it is necessary to complete the information only with the information recorded on the magnetic tape. It is possible. Therefore, a large-capacity storage means for storing information for retrieval (information of a title number and information of association between a title number and time code / date / time data in the prior art) on the device side is provided. The need to secure the information is reduced, and it is possible to eliminate the need to store various types of character information in the form of codes. The magnetic tape processed as described above can be handled similarly in other magnetic recording / reproducing devices having the same function.

In particular, since it is possible to select desired character information from a plurality of character information instead of only one as the character information of the original audio information and to superimpose the selected character information on the video information. On the user side, there is the convenience of realizing subtitles superimposed by changing the language and other conditions, and the maker side has the merit that multiple types of subtitles superimposed can be recorded on a common magnetic tape to stimulate demand.

In other words, since none of the character information is missed, it is not necessary to limit the number of pieces of character information to be coexistent to one, and a plurality of pieces of character information can be recorded simultaneously, and effective use of the magnetic tape can be achieved. it can.

The character information may be based on a character code, or may be based on bitmap data. That is, it may be coded character data (character data) of a certain character font (character style). In this case, any type of character font may be used. Alternatively, it may be handwritten characters arbitrarily created. It should be noted that the term “character information” may include not only information directly related to translation but also character information for explaining and explaining a scene of a video, a title of a content, and the like. Also,
When referring to "character information", it does not matter whether a digital signal or an analog signal is used.

According to a third aspect of the present invention, in the magnetic recording / reproducing apparatus according to the first aspect, the character information is recorded by adding identification information to the character information, and the character information is extracted from a set character information selection signal and a reproduction signal during reproduction. Character information matching the character information signal is selected and superimposed on the video signal and output.

The display condition information is extracted from the character information selected at the time of reproduction, and is superimposed according to the extracted display condition information at the time of superimposing the separated video information and the selected character information. Things. According to the eighth aspect, arbitrarily selected character information can be displayed under arbitrarily set display conditions, and a variety of video projection states can be realized. It should be noted that such a display condition is, for example, a display position of a subtitle superimposed on the screen.

The track pattern (recording format) on the magnetic tape 100 does not need to be limited to those shown in FIGS. 3 and 5; for example, one track of a synthetic video signal and a synthetic audio signal and a synthetic translation character signal. It is possible to adopt a mode in which one track and 2 are alternately arranged, and the mode is arbitrary.

In the above description, a signal for one frame has been described. However, it is not always necessary to be limited to the signal. For example, a signal for one field may be similarly processed.

In the above description, the translated character recording area 120
Is approximately the same length as the video / audio recording area 110, but it is not always necessary to be limited to this, and it may be 1.5 times or 2 times. When the speed is doubled, the tape traveling system is tripled and the rotating cylinder is tripled, or the tape traveling system is tripled and the number of magnetic heads is tripled. Generally, when n times, the tape traveling system is set to (n + 1) times speed and the rotating cylinder is set to (n + 1) times speed, or the tape running system is set to (n + 1) times speed, and the number of magnetic heads is increased. (N + 1) times.

In the above description, the translated character recording area 120
, We decided to co-record only the translated character information in multiple languages, but there is no need to be caught in that.
The translated character information and the translated voice information may be mixed. In this way, for example, it is possible to watch a movie or learn a foreign language while collating the English subtitle superimposed with French audio, or collating the German subtitle superimposed with Italian audio.

Further, different contents may be recorded in a single language without being limited to coexistence recording in a plurality of languages. As an example of use in this case, for example, the viewer can display his / her favorite information by separately recording character information such as the history, technology, and introduction of the author in a museum or art museum. .

In the above, in FIG. 3, the translated character signal processing circuit 33 is provided with shuffling means 4 ₁ , 4 _2.
... provided 4 ₁₂ but is not always necessary to be bound thereto, it is also possible to omit the shuffling means 4 _1, 4 ₂ ... 4 _12. However, in that case, in order to match the synchronization for delay in shuffling function compressing unit 2 in the video signal processing circuit 31 (usually for one frame delay), portions of the shuffling unit 4 _1, 4 ₂ ... 4 ₁₂ Is provided with delay means.

According to the magnetic recording / reproducing apparatus of the present invention, the video information / audio information and the translated character information of a plurality of languages coexist on a common magnetic tape while securing the originality of the original video information / audio information. Can be recorded
When reproducing the magnetic tape, an output video signal in a state where the selected translated character information is added to the video information can be obtained. Nevertheless, since all of the underlying information is self-containedly recorded on the magnetic tape, the load on the apparatus is reduced and the configuration is simplified. Further, since it is not necessary to store two volumes of the original tape and the completed tape, the storage space can be reduced. In particular, since the translation character information of a desired language can be selected from the translation character information of a plurality of languages instead of a single language, there is a convenience that the user side can realize a subtitle supermarket or the like in a different language. On the side, there is a merit that demand can be stimulated by recording subtitles in multiple languages and multiple pieces of information on a common magnetic tape. This means that when an unspecified number of people watch content viewed by an unspecified number of people in a library or a movie displayed on a monitor display installed on each seat of an aircraft, they can listen in their own language, It is possible to obtain the information that the user wants, and the convenience is greatly improved.

Further, by changing the display position of a subtitle supermarket or the like, expandability for richer expression can be ensured.
