Video transmission over Internet can greatly benefit from adapting video content to diffserv network parameters, to better support the application requirements. In this paper, a novel content-aware packet priority ordering and marking scheme is presented for streaming H.264 coded video over differentiated services enabled networks. The scheme takes advantage of flexible macroblock ordering (FMO) coding...
Rate distortion optimization (RDO) based spatial intra prediction is an important new feature in H.264/AVC. It chooses the best mode for each MB by exhaustively examining all possible modes. Thus,drastically increased computation complexity is involved. This paper proposes an efficient fast intra mode decision algorithm.Prewitt operator is used to extract each block's two most dominant edge directions...
