[Industrial Applications]

The present invention relates to a device for inputting a subtitle into a TV program and a video tape, and more particularly to a device suitable for Korean caption.

[Prior Art and Problems]

Unlike subtitles, which display urgent news or reminders on a normal TV screen, the metabolic information supplementary broadcast refers to a broadcast in which the contents of the TV screen can be viewed by the viewer's choice.

Normally, closed caption broadcasting is determined not only by the viewer but also by the selection of the broadcasting person, and is often called an open caption.

On the contrary, the present invention relates to a method in which a broadcaster always transmits meta information to ordinary TV broadcast information, and allows the viewer to view the meta information by selecting a viewer, which is commonly referred to as closed caption.

On the other hand, in the method of recording a video tape, a character such as a caption of a TV can be inserted, or a so-called closed caption video tape can be produced by adding the metabolism information which is an object of the present invention,

Such TV programs and video tapes are very important for the deaf (hearing impaired) who can see the screen but can not hear the voice, and it is also very useful for foreign language learning.

In particular, the necessity for the welfare of farmers and others was emphasized and research on this was done early.

Since hearing impaired people can not understand the contents of TV broadcasts without a sign language scene, the United States has broadcasted texts in English in 1978 for English audiences.

On the other hand, researches on methods and apparatuses for information on the ambassadorial information have been made, and the results have been published recently and commercialization is being promoted.

However, caption videotapes kept by broadcasting stations or caption videotapes distributed on the market are all recorded in American way.

[Problems to be solved by the invention]

However, such conventional videotapes cause a lot of confusion to the consumers when Korean caption broadcasting starts and the receivers and the VTRs are supplied.

That is, caption tapes of American type are useless in broadcasting, receiver, and VTR using Korean caption.

In order to use the obsolete tape, the caption data embedded in the tape should be replaced with Korean caption data.

Accordingly, an object of the present invention is to provide an apparatus for converting existing US-style caption data into Korean-style caption data and recording it on a tape.

It is another object of the present invention to provide a device for easily inputting caption data using a more advanced peripheral device.

The present invention also provides a device for inputting a metabolic film through a character input device.

[Example]

Hereinafter, the present invention will be described in detail with reference to embodiments and other drawings.

FIG. 1 is a diagram showing an example of a metabolic film conversion apparatus of the present invention.

This metabolic transducer is a device for converting the caption data according to the conventional method into the Korean metabolic subtitle information.

In the figure, reference numeral 21 denotes a synchronization separator which separates a composite signal (i.e., a sync signal) from an external video signal and detects a data detection position indicating the position of the caption data carried on the video signal, It is the role of telling.

Here, the video signal is sent from a VTR or the like that reproduces the tapes.

On the other hand, a data detecting unit 22 decodes a caption signal on the basis of a data detection position transmitted from the sync separation unit 21, and sends the decoded signal to a serial / parallel conversion unit.

Reference numeral 23 denotes a serial / parallel converter for converting a serial subtitle signal sent from the data detector 22 into a parallel signal.

The CPU 24, which acts as a controller, reads the parallel-converted signal and converts it into a signal having a different caption scheme.

This function can also be accommodated in an external computer or the like other than the metabolic transducer.

On the other hand, if there is a large amount of caption metabolism and the conversion processing can not be performed only by the memory of the CPU itself, the serial / parallel conversion unit 23 stores the parallel converted data in the buffer and the CPU 24 reads the buffer 25, Or the signal of the other.

An example of converting the metabolic subtitles using the metabolic transducer of the above configuration, specifically, an example of converting the US caption metabolic subtitles into the Korean caption metabolic subtitles will be described in detail.

First of all, the US caption method is specified in detail by US FCC.

A brief look at this is as follows.

For texts that are unrelated to the subtitles, there are 15 lines * 34 black boxes. The maximum number of characters per line is 32 characters excluding the blank part of the front and back sides of each line.

In addition, for caption, only 4 lines can be displayed simultaneously, and there are 3 display modes.

Pop on, paint on, and roll up.

On the other hand, there are two kinds of attributes for displaying characters.

That is, location property and character property.

The location attribute indicates the location of a cell (tab or indent) or line, and the character property indicates color, italics, underline, or flicker.

The control codes to be transmitted twice are as follows.

First, the MSC (Mode Switching Code) is a code for specifying text and mode.

Preamble Address Code (PAC) is a code that specifies a language and specifies fields, lines, and attributes.

MRC (Mid-Row code) is for changing the attributes of color and underline in the middle of a row.

On the other hand, the end-of-caption code (EOC) is a code that changes the memory displayed on the current screen in pop-on mode.

Character codes consist of alphabetic characters consisting of ASCII codes and special characters.

The transmission order of the character code and the control code is as follows.

First, in the pop-on mode, the CR (Return Return) acts as a scroll up, and the order is as follows.

MSC + text + text + CR

In pop-on mode, CR has no meaning and the order is as follows.

MSC (RCL: Resume Caption Loading) + PAC + text + (MRC) + text + EOC

MSC (RCL: Resume Caption Loading) code shows that it is pop-on, and EOC changes the displayed value.

Next, in the paint-on mode, CR is not meaningful and the order is as follows.

MSC (Resume Direct Loading) + PAC + text + (MRC) + text + (DER: Delete to End of Row)

In the roll-up mode, CR means scroll up in the window, and the order is MSC (2RU, 3RU, 4RU) + PAC + text + (MRC) + text + CR + text.

Here, the line designation of PAC means base row designation, and the default value of line designation is 15.

On the other hand, the outline of the Korean method is as follows.

The screen display mode is set to the dialogue information (subtitle) mode and the non-dialogue information (TEXT) mode, that is, the text mode.

The non-metabolic information is displayed in the entire character display area. Continuously display 5 lines or so.

The dialogue information mode is again divided into pop-on, roll-up, and roll-down.

The pop-on mode is a form in which the dialogue appears on the screen suddenly. It is mainly used when processing a plurality of people's dialogue at the same time.

The roll-up mode and the roll-down mode are to roll and display the current line up or down, respectively, each time a roll-up or roll-down control code is received.

On the other hand, the method of using the control code does not specify the specific mode to the control code, but performs the display control as needed every time.

It is necessary to use the pop-on mode control code by continuously transmitting (screen clear control code) + string code + (screen display control code), a few seconds, and (screen clearance code) + string code + none.

Roll mode does not require (roll-up mode control code) and (area designation code) because it uses individual control codes such as 2-line rollup and 3-line rollup integrated with area designation and line feed function.

Table 1 shows the control codes and their functions.

In addition, at least one control code must be transmitted every 48 words (24 characters) transmission, and the vertical position control code must be transmitted once every 5 lines, Goes.

The process of converting from the above-described US format to the Korean format, that is, the process of converting the US-style caption data detected by the CPU 24 of the metabolic subtitle conversion apparatus into the Korean caption will be described.

First of all, the character code is basically converted from ASCII to Hangul completion code.

In addition, since FCC standard is 15 lines and Korean type is 10 lines, line position conversion should be considered in conversion.

Thus, 1-5 lines are converted to 1-5 lines, 5-10 lines are converted to 1-5 lines, and 10-15 lines are converted to 5-10 lines.

However, if there are metabolic subtitles, such as 4, 5, and 6, for example, between 5 and 6 lines of pop-up, the contents may be reversed.

1) Conversion of text poem

If the MSC of the FCC specifies text, the MSB (Most Significant Bit) must be set to 1 in the code converted in Korean until the caption is specified again.

In addition, since additional information in Korean format is transmitted on a page-by-page basis, count the CRs of the FCC standard and input the beginning and end of the page every 15 lines.

The CR also converts to APDR (Active Position Down Roll).

2) Pop-On Time Conversion

The transmission order of the pop-on Korean type is as follows.

(+) + (+) + (+) + (+) + (+) + (+) + (+) + (+) + Converts to screen view.

CR also converts to APDR.

3) Paint on-time conversion

Because Korean does not support paint on, paint on converts to pop on.

In other words, DER, etc. should be converted to screen erasure and screen display.

4) Converting during rollup

The transfer order of Korean type when rolling up is as follows.

Screen display + (other control code) + string + (other control code) + string + (2 to 5 lines up)

FCC's 2RU, 3RU, and 4RU are recognized as roll-up start, and this code determines the corresponding 2- to 4-line rollup.

During roll-up, the designated space in the PAC is valid until another MSC (2RU, 3RU, 4RU) arrives, so you should insert the cell position control code in each other line in each other control code.

Also, you should always put a screen view at the beginning of each line.

In this way, the caption of the FCC method is converted into the Korean type caption.

On the other hand, the above-described invention is not only used for converting from the FCC method to the Korean method, but it is also possible to reverse the method.

Fig. 2 shows an example of a metabolic film input apparatus using the above-mentioned metabolic film conversion apparatus.

In the figure, reference numeral 20 denotes a standard conversion apparatus which is the same as or slightly modified from the above-mentioned metabolic film conversion apparatus, extracts caption data from a video signal, converts the caption data into caption data suitable for a desired format,

10 is a computer for caption input, which can be a normal PC or a dedicated computer.

Receives the caption data from the signal from the standard conversion device 20, and transmits the caption data to the caption signal generation encoder by matching with the time code.

The time code at this time is transmitted to the encoder 30 immediately after matching the caption data if the VTR or the like sends a time code to the VTR or the like which is the source of the original video signal, Or stored on a disc, then edited, etc., and sent to the encoder.

That is, a standard transcoding device 20 receives a sentence corresponding to each scene of a master recording tape or video tape reproduced by a VTR or the like, stores the time code and position information corresponding thereto in a file, and outputs the same to a subtitle signal embedding encoder .

For this purpose, the PLAY, REW, FF, STOP, and SHUTTLE of the VTR must be able to be remotely controlled easily, thereby facilitating the input of the metabolism information.

In addition, input video signal and subtitle to be input are overlaid on the monitor so that a separate monitor is not required.

Reference numeral 30 denotes an encoder for generating a caption signal, which serves to synthesize caption data from the computer for inputting the caption and the caption without caption.

This can be configured using the ICs already provided.

In addition, the caption signal embedding encoder 30 may be mounted on the computer 10 in a board form.

Reference numeral 40 denotes a translator, which translates the caption in the standard conversion device 20 into another language.

In other words, English is translated into Korean or Korean into English.

The translator 40 may be provided in the standard conversion apparatus 20 or the subtitle substitution input computer 10 so as to be integrated with the standard conversion apparatus 20 or the subtitle substitution input computer 10.

A method of inputting a metabolic film using the metabolic film input device having the above-described configuration will be described.

First, the VTR is controlled to input a sentence corresponding to the dialogue, and the time code of the automatically started metabolic start scene is stored in the time code area of the editor file, and the overlaid subtitle on the VTR image displayed on the computer monitor is moved to the desired position So that it is automatically input into the location area of the editor file.

When the input of the metabolism information is finished, it is necessary to input the metabolism information into a video signal for inputting the metabolism information for recording or the like.

The method uses a VTR for reproduction and a VTR for recording.

It is the VTR for reproduction that outputs the original video signal in the second view, and the VTR for recording by inputting the video signal containing the caption, that is, the output of the encoder 30 for generating the metabolism film.

After the time codes of the reproducing VTR and the recording VTR configured as described above are matched with each other, the reproducing VTR time code is read at the same time to read the reproduction VTR time code, and the subtitle subtitle information is outputted to the subtitle subtitle encoder 30 in accordance with the time code.

And the position designation code for designating the direction of the writing of the subtitle and the position of the subtitle is inserted in an additional non-specific manner.

In this mode, the information of the computer 10 for inputting the metabolism film is transmitted to the ambassador caption encoder 30.

On the other hand, the computer 10 for inputting a metabolic caption may immediately transmit the metadata to the encoder 30 for recording in real time without storing and editing the metabolism film.

The device may also have the capability to convert caption data of different formats into a desired format, as the case may be.

FIG. 3 is a view showing another embodiment of the present invention. FIG.

In this embodiment, instead of the conversion device such as the standard conversion device 20, the voice recognition device 50 or the character recognition device 60 is used to input the metabolism film.

In the figure, reference numeral 50 denotes a voice recognizer for inputting a voice and recognizing it and converting it into a character.

The speech recognizer (50) is constructed using a commercially available one.

The hardware can also be configured to be stored in a storage device (not shown) of a computer 10 for inputting a program for metabolical subtitles to be installed in the form of a board on the computer 10 for inputting the subtitle film and performing speech recognition have.

The input to the voice recognizer 50 may be via an external microphone 51, for example, or may be connected to an output signal such as a VTR for generating an original video signal.

On the other hand, 60 is a character recognizer that inputs characters in an image form, recognizes them, and converts them into characters.

This character recognizer (60) is constituted by using a commercially available one.

In addition, the hardware is configured to be mounted on the computer 10 for inputting a metabolic film and stored in a storage device (not shown) of the computer 10 for inputting a character image, It is possible.

The input to the sentence recognizer 60 may be via the scanner 61 or the camera 62, for example.

The method of inputting the metabolic film using the apparatus having the above-described configuration is the same as that of the above-described embodiment, and thus the description thereof is omitted.

Also, in place of the voice recognizer or the character recognizer, the user inputs the metabolism information through a character inputting device such as a keyboard, and transmits it to an external device such as an encoding device, together with a control code for displaying the metabolism information, .

This will be described in more detail as follows.

First, the user inputs a dialogue through a character input device such as a keyboard.

The computer for metabolic caption inputting this metabolism sends the metabolism to the encoder 30 together with the control code corresponding to the mode instructed by the operator based on the instruction of the external operator.

Since the subsequent steps are the same as those in the above embodiment, the description thereof will be omitted.

Meanwhile, it is possible to input a dialogue through a character input device such as a keyboard, store it in a file form, and transmit it to the outside.

That is, a time designated by the operator, in order, and transmits the same to the encoder together with the control code corresponding to the display mode designated by the operator.

At this time, the operator should instruct the computer for inputting the subtitles to display the video to be played and to transmit the subtitles to the video.

When it is difficult to designate one by one, it is preferable to unify the display mode into a predetermined mode and change it only when necessary.

[Effects of the Invention]
