| Abstract: | Video communication channels and error control of video information are discussed in detail according to the practical situations of traction power system. E1-based video communication network is designed, the difficulties of video control and video distribution are solved; Several video coding methods suitable to the traction power system, such as M-JPEG, MPEG-1 and H.263 are analyzed. Error control and resilient methods, such as error detection and error concealment in decoding program are also discussed to improve the reliability of video signals. It is proved by experiments that the RVMS, which has high adaptability to communication channel and high anti-interference ability, is especially suitable to remote video monitoring of traction substations. |
