SIGNAL PROCESSING-IMAGE COMMUNICATION 2002年 第8期17卷 597-609页
作者: Jung, HS Kim, RC Lee, SU Seoul Natl Univ Sch Elect Engn & Comp Sci Inst New Media & Comm Gwanak Gu Seoul 151742 South Korea Seoul Natl Univ Dept Elect & Comp Engn Seoul South Korea
The MC-DCT-based video coding has been generally used for its efficiency and easy implementation, but it is very vulnerable in error-prone environments. In this paper, we address an error-resilient video coding using ... 详细信息

作者: Rane, S Girod, B Stanford Univ Informat Syst Lab Stanford CA 94305 USA
We propose the use of H.264 redundant slices for Systematic Lossy error Protection (SLEP) of a video signal transmitted over an error-prone channel. In SLEP, the video signal is transmitted to the decoder without chan... 详细信息
