摘要： 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.
