ABSTRACT:
A character display circuit in which a circuit for generating a character display timing signal in synchronism with vertical and horizontal synchronizing signals controls the frequency of dots constituting a character such that it is an integer multiple of the coding frequency for bits of a closed caption code, character coded data conforming to a format of the closed caption code is generated in synchronism with a predetermined horizontal synchronizing signal during the blanking period of a video signal using dot patterns for encoding character data, and the character coded data is superimposed on the video signal.
