Rate-Distortion Optimized Selection of Motion Vectors for Video Transmission over Packet-Loss Channels Jing YANG Xiangzhong FANG Publication IEICE TRANSACTIONS on Communications Vol.E89-B No.12 pp.3494-3496 Publication Date: 2006/12/01 Online ISSN: 1745-1345 DOI: 10.1093/ietcom/e89-b.12.3494 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Multimedia Systems for Communications Keyword: motion estimation, error propagation, rate-distortion optimization, low-bit-rate, packet loss, Full Text: PDF(279.7KB)>>
Summary: The selection of motion vectors plays an important role in the error propagation process between inter-frames. In this letter, an end-to-end prediction error calculation method is proposed and is used for the rate-distortion optimized selection of motion vectors. Simulation results show that the robustness of encoded video streams under error-prone environment is improved. | |||||
