摘要: In this paper we propose a new H.264 SVC transrating architecture for spatially scalable compressed video streams. The algorithm is low complexity based, it applies to pre-encoded streams and allows fine bit rate granularity while keeping highest spatial resolution. Simulation results demonstrate that transcoded produce satisfying picture quality even at reduction up 66%. comparison with MGS shows the proposed aslgorithm offers performances compared when remains limited. Moreover scalability obtained thanks our if bitstream has not been processed using right from start.
