Claims (7)

A data slice section 3 for detecting caption data from the composite video signal of TV and V-Cal selected by the first signal selecting section 1 and generating gum data as a reference for the caption data; and the data slice section 3 Microcomputer 4 for controlling the entire operation of the system in accordance with the detection data and the reception control signal input from the light-receiving unit 8, and is enabled in accordance with the control signal of the microcomputer 4 and output from the data slice unit (3) A video recording processing unit (2) for storing the subtitle data and the video signal selected by the first signal selecting unit (1) in units of frames, and processing and outputting the stored data; and the video signal and the video signal of the video recording processing unit (2). A second signal selector 10 for selectively switching the current video signal and subtitle data of the first signal selector 1 and the data slice unit 3 to the chroma image processor 5, and a third signal selector ( 7) Selected TV and Bro And a voice recording processing unit 6 for storing the voice signal of the seed according to the control signal of the microcomputer 4 and processing the stored voice data and outputting the stored voice data through the voice output unit 9. Subtitle audio repeat playback system. The video recording processing unit (2) according to claim 1, further comprising: an analog / digital conversion unit (2a) for converting the first signal selection unit (1) and the caption data of the data slice unit (3) into digital signals; The image memory unit 2a is enabled according to the control signal E2 of the microcomputer 4 and stored in the image memory unit 2a, and the analog // is enabled according to the control signal E2 of the microcomputer 4. And a digital / analog converter 2c for converting the video data stored by the digital converter 2a one frame at a time into an analog signal and outputting the analog signal to the second signal selector 10. Subtitle audio repeat playback system. The audio recording processing unit (6) according to claim 1, further comprising: a switching unit (6a) for blocking and passing the audio signal selected by the third signal selection unit (7) in accordance with the control signal (C1) of the microcomputer (3); The voice discriminating unit 6b for discriminating the presence or absence of the voice signal through the switching unit 6a and being input to the microcomputer 4 and the control unit S1 of the microcomputer 4 is enabled. The analog / digital converter 6c for converting the voice signal of 6b into a digital signal and the digital signal of the analog / digital converter 6c are converted into analog signals according to the control signal S1 of the microcomputer 3. And a voice processing unit 6d for outputting to the audio output unit 9 and outputting a pulse according to the voice repetition to the microcomputer 4, and storing and storing voice data processed from the voice processing unit 6d. And a voice memory section 6e for outputting data to the voice output section 9 through the voice processing section 6d. Captions voice repeat playback system of closed captioning in. Extract the caption data and the detection data according to the caption data from the external video signal, and store the audio signal in the voice memory unit according to the presence or absence of the audio signal corresponding to the video signal and the received repeat request control data, and output the audio signal. In the first step of outputting the negative data, and when inputting the repeat request control data in the first step, the image data is stored in the memory unit in the projection, and the previous detection data is compared with the current detection data. A second step of determining a signal storing operation and a third step of continuously storing the voice signal in the voice memory unit according to the determination of the second step, reading the stored voice data, and repeatedly outputting the set number of repetitions. A subtitle audio repeat playback method of a subtitle broadcast. 5. The method of claim 4, wherein the first process comprises: a first step of setting a repetition frequency, a second step of determining detection data for caption data after setting the repetition frequency, and a voice memory unit and an image when the detection data is input; A third step of clearing the memory unit, a fourth step of determining whether or not the voice signal is input after the third step, a fifth step of enabling the voice memory unit to store and output the voice signal when the voice signal is input; And a sixth step of determining whether or not the repeat request control data is input after storing the voice signal. 5. The method of claim 4, wherein the second process comprises: a seventh step of enabling an image analog / digital conversion unit and an image memory unit when inputting repetition request control data; and an eighth step of starting storing image data in the image memory unit; And a ninth step of determining whether the stored image data is one frame, a tenth step of blocking an input image signal by disabling the video analog / digital converter when the one frame is stored, and the previous detection data after storing the one frame. Subtitle broadcasting of subtitle broadcasting, characterized in that the first step is to compare the current detection data with the first detection process and continue to perform the voice storage operation if it is the same, and if the difference is different, stopping the storage operation according to the repeated request control data. Voice repeat playback system. 5. The method of claim 4, wherein in the third process, the detection data is different in the second process, and when the repetitive request control data is input, the twelfth step of reading data from the image memory unit and outputting one frame to the second signal selector; A thirteenth step of determining whether the input of the voice data corresponding to one frame of data is finished; a fourteenth step of blocking the voice switching unit if the input of the voice data is terminated; and a reset of the count after the voice interruption; A fifteenth step of repeating the voice signal by repeatedly reading the voice memory unit after the count reset; and a seventeenth step of comparing the repeated number of times and the set count value with each other; 18th step of transmitting the subtitle, and if the comparison value is the same, the 19th step of disabling the video, audio memory unit, characterized in that the closed caption voice repeated playback system. ※ Note: The disclosure is based on the initial application.
