Error Resilient Video Communication Based on Picture Level Adaptive Frame/Field Coding

Packet loss protection method based on picture level adaptive frame /field coding （PAFF）was presented. Firstly,the end-to-end rate-distortion analysis for PAFF on the current frame was performed. Secondly,in order to evaluate the severity of error propagation in the following frames,the error propagation intensity and human visual quality sensitivity of different areas were taken into consideration. It was followed by the quantification of relative importance. Finally,the proper coding mode was chosen utilizing an unequal comparison procedure. The simulation results show that the proposed method can improve peak signal-to-noise ratio （PSNR） up to 0. 9 dB and 1. 6 dB comparing with the field only and the dispersed flexible macro-block ordering （FMO）only methods respectively.
