Multi-channel video transmitting system and method

The invention discloses a multi-channel video transmitting system and method. The method comprises a transmitting end and a receiving end. The transmitting end comprises a video source and a video code flow transmitting device. The receiving end comprises a video code flow receiving device. The transmitting end of the invention further comprises a multi-channel JPEG coder for performing JPEG compression to the video code flow to generate a coded image sequence. The receiving end further comprises a multi-channel JPEG decoder for performing JPEG decompression to the video coded image sequence to generate the video code flow. The invention can fully utilize the parallelism and low complexity of JPEG to compress the high definition video and can make the transmitting bandwidth based on the IP network satisfy the real-time requirement of the high definition video in order to realize the optimal transmitting effect of the high definition video with comparatively low development cost under limited network bandwidth.
