Abstract: A closed-caption broadcasting and receiving method and apparatus. According to the closed-caption broadcasting method and apparatus, character information and control information are inputted, and a control code of 2 words and a character code of 2 words including a syllable character completion type code are produced. The control code is obtained by combining the control information with a mode control bit and a parity bit, and the character code is obtained by combining the character information with a mode control bit and a parity bit. A digital-modulated caption signal is produced by inputting the control code and the character code, and is coded on a scanning line which does not affect a television video signal to be transmitted.

Abstract: A closed-caption broadcasting and receiving method and apparatus. According to the closed-caption broadcasting method and apparatus, additional information is inputted and the input of word information is checked. If the word information is inputted, it is selected, while if not, the additional information is selected. Thereafter, character information and control information of the selected information are inputted. A control code of 2 words is obtained by combining the control information with a mode control bit and a parity bit, and the character code of 2 words including a syllable character completion type code is obtained by combining the character information with a mode control bit and a parity bit. A digital-modulated caption signal is produced by inputting the control code and the character code, and is coded in a scanning line which does not affect a television video signal to be transmitted.

Abstract: A closed-caption broadcasting and displaying method and apparatus. According to the closed-caption broadcasting method and apparatus, a caption signal including character information and control information is encoded in a scanning line of each field of a television broadcasting signal to be transmitted, which does not affect the television broadcasting signal. Control information on the writing direction and display position among the control information is repeatedly transmitted at predetermined intervals.

Abstract: A closed-caption scrolling method and apparatus suitable for displaying a closed caption including syllable characters and capable of reducing the memory capacity. According to the method, the caption signal is encoded in a line of each field of a broadcasting television signal which does not affect the broadcasting signal, and then transmitted to be displayed on a screen of a receiver. A control code for controlling the size of a scroll region and the scrolling direction is produced, so that character information following the control code is displayed on the predetermined scroll region, being scrolled in a predetermined direction, by the control code.
