Abstract
The invention relates to the art of communications and particularly to a video signal transmission method, apparatus, system and terminal, where the method includes: separating a current raw digital video signal acquired by a video camera core into a luminance signal and a chrominance signal; converting the luminance signal and the chrominance signal into an analog video signal; transmitting the analog video signal to a master control chip board through an electrically-conductive slip ring; and converting the analog video signal back into the current raw digital video signal in the master control chip board. With the video signal transmission method, apparatus, system and terminal according to embodiments of the invention, the integrity of the transmitted video signal can be improved to thereby guarantee the quality of the video signal.
