Error Resilient Dual Frame Motion Compensation with Uneven Quality Protection

Summary form only given. In this paper, an error resilient JU-DFMC is proposed for video transmission over error-prone channels. In the proposed error resilient JU-DFMC, a new error resilient prediction structure of DFMC is firstly presented. The LQF can adaptively select reference frame according to different packet loss rate. Then the MB information is divided into two partition header information (A) and texture coefficients (B). Based on the partition, an end-to-end distortion model is applied for macroblock (MB) level mode decision. Finally a frame level rate distortion cost scheme is proposed to determine how many times the header information will be transmitted in a high quality frame (HQF). The HQF (LTR) is given more protection. The experimental results show that the proposed method can achieve better performance than the previous DFMC schemes. In the future, how to determine LQF header transmission times will be further exploited.
