Error Resilient Dual Frame Motion Compensation with Uneven Quality Protection
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. Then 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 experimental results show that the proposed method can achieve better performance than the previous DFMC schemes.
