Advanced bitstream rewriting from H.264/AVC to SVC

In previous work, we introduced an H.264/AVC-to-SVC transcoder for creating SVC streams with multiple quality layers from a single-layer H.264/AVC stream. This architecture was able to restrain the error drift due to requantization of the residual coefficients. In this paper, we show that it is possible to further reduce the complexity, and completely eliminate the drift in the enhancement layer, by making use of the bitstream rewriting functionality in SVC. We propose different novel architectures, which are able to flexibly distribute the data among the different created layers.
