Abstract :
Unequal error protection on video transmission is widely used to combat with bit errors in the wireless channel. However, current UEP schemas are based on heuristic approaches and taking no account of the characteristics of human visual system. In this paper, a novel unequal error protection schema for wireless H.264 video transmission based on a modified perceived motion energy (PME) model is presented. According to the sensitive characteristics to video motions of human eyes, the proposed modified PME model taking account to the encoding features of H.264/AVC standard to analyze and model the motions in H.264/AVC encoded video. Based on this model, the video bitstream is divided into several quality layers and unequal error protection is designed to protect the layered bitstream for the transmission over wireless channels. Experiment results show that higher video transmission quality is obtained.
