摘要:
A system for superimposing color characters on video reproduction signals: A character signal is modulated by a color subcarrier phase-locked to a burst signal of video reproduction signal, and the display position of each line is controlled by the pulse obtained on the basis of the horizontal synchronizing signal of the video reproduction signal. A desired color character can be superimposed on a video reproduction signal without drift of the character.
