The invention discloses a video compression remote transmission system for feeding back coarse quantization reconstructed frames, comprising an information source and an information sink. The information source comprises an information source video encoder, a forward direction transmission transmitter and a reverse direction feedback receiver, wherein the forward direction transmission transmitter and the reverse direction feedback receiver are both in connection with the information source video encoder. The information sink comprises an information sink video decoder, a forward direction transmission receiver, and a reverse direction feedback transmitter, wherein the forward direction transmission receiver and the reverse direction feedback transmitter are both in connection with the information sink video decoder. The forward direction transmission transmitter is in connection with the forward direction transmission receiver; the reverse direction feedback transmitter is in connection with the reverse direction feedback receiver. The video compression remote transmission system feeds back reconstructed video frame information of a remote video decoder on a reverse direction channel, allowing local video decoder reconstructed frames in a local video encoder to be simultaneous with remote video decoder reconstructed frames; the coarse quantization of a transmission data rate is conveniently reduced, and a coarse quantization method is employed for reconstructed frame feedback to reduce a required data rate, thereby reducing the requirement for a decoder operation speed.
