| Abstract: | In this paper, we propose a method for multiple description coding (MDC) of Flash Video stream (FLV). Our target codec of FLV is Sorenson H.263. Conventional MDC methods had disadvantages that they required large redundancy. We proposed a method that considers "patterns" of a macroblock, and it changes how to treat DCT coefficients of a macroblock according to the pattern. As an experimental result, we could reduce redundancy of the encoded stream while keeping the video quality. |
