چکیده
This document contains a description of an SNR-scalable extension of H.264/AVC [1]. To achieve an efficient SNR-scalable bitstream representation of a video sequence, the temporal dependency between pictures is coded using an open-loop subband approach. In this codec, most components of H.264/AVC are used as specified in the standard while only a few have been adjusted to the subband coding structure. We have tested a first version of the approach with QCIF and CIF resolution sequences obtaining some promising results.

A hybrid video codec based on extended block sizes, recursive integer transforms, improved interpolation, and flexible motion representation
This paper describes video coding technology proposal submitted by Qualcomm Inc. in response to a joint call for proposal (CfP) issued by ITU-T SG16 Q.6 (VCEG) and ISO/IEC JTC1/SC29/WG11 (MPEG) in January 2010. Proposed video codec follows a hybrid coding approach based on temporal prediction, followed by transform, quantization, and entropy coding of the residual. Some of its key features are ...
متن کاملRate Control for Low Delay Video Communication of H.264 Standard
The demand for multimedia services is increasing rapidly in the last years. Therefore, efficient video compression has become a very important research for the multimedia communication. H.264 is the state-of-the-art digital video coding recommendation, which is also known as H.264/MPEG-4 Advanced Video Coding (H.264/AVC) (ITU-T, 2003). The standard is a joint collaborative effort between the IS...

Zusammenfassung Bewegungskompensierte Prädiktion mit Hilfe mehrerer vergangener oder zukünftiger Referenzbilder, so genannte Multiframe-Prädiktion, kann die Kompression von Videosignalen verbessern. Multiframe-Prädiktion lässt sich in Verbindung mit den von MPEG bekannten P-Bildern, oder auch – durch Multihypothesen-Prädiktion – in Verbindung mit B-Bildern verwenden. Dieser Aufsatz fasst die ak...
متن کاملThe H.264/AVC Video Coding Standard
T he H.264/MPEG-4 Advanced Video Coding standard (H.264/AVC) is the newest video coding standard jointly developed by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). H.264/AVC has achieved a significant improvement in compression performance compared to prior standards, and it provides a network-friendly representation of the video that addresses...
متن کاملMulti-frame motion-compensated video compression for the digital set-top box
Motion-compensated prediction based on multiple previous or future frames can enhance the compression efficiency of video coding. Multi-frame prediction can be applied as an extension to P-Pictures, but also to B-Pictures in the form of multi-hypothesis prediction. We review recent advances, several of which have been embraced by the ITU-T Rec. H.263 and the emerging JVT/H.26L standard, jointly...
