Abstract
A novel prototype system to obtain real-time and high quality video transmission in wireless environment of high packet loss rate and limited bandwidth was introduced.The wireless terminal used high performance multimedia Digital Signal Processor(DSP) as video processing and control core.Video signal was encoded by H.264 and transmitted over dual-channel of Enhanced Data rate for GSM Evolution(EDGE) to the video services.A transmission method and an error conceal method based on dual-channel buffers were proposed.The experimental results show that the system can transmit real-time video(CIF) and achieve satisfactory reconstructed video.
