The European STREP Project SUIT involves the development of a multiple description scalable video codec for the transmission of video content over DVB-T/H and WiMAX channels. In this paper, we elaborate on the architectural design choices for such a multiple description transmission system, which utilizes H.264 Scalable Video Coding (SVC). We follow a(More)
In video coding systems using adaptive arithmetic coding to compress texture information, the employed symbol probability models need to be retrained every time the coding process moves into an area with different texture. To avoid this inefficiency , we propose to replace the probability models used in the original coder with multiple switchable sets of(More)
In this paper, we present motion-refined transcoding of H.264/AVC streams to SVC in the transform domain. By accurately taking into account both rate and distortion in the different layers on the one hand, and the SVC inter-layer motion prediction mechanisms on the other hand, the proposed transcoding architecture is able to improve rate-distortion(More)
