Abstract

A highly scalable wavelet video codec is proposed for Internet video streaming applications based on the simplified JPEG-2000 compression core. Most existing video coding solutions utilize a fixed temporal grouping structure, resulting in quality degradation due to structural mismatch with inherent motion and scene change. Thus, by adopting an adaptive frame grouping scheme based on fast scene change detection, a flexible temporal grouping is proposed according to motion activities. To provide good temporal scalability regardless of packet loss, the dependency structure inside a temporal group is simplified by referencing only the initial intra-frame in telescopic motion estimation at the cost of coding efficiency. In addition, predictive-frames in a temporal group are prioritized according to their relative motion and coding cost. Finally, the joint spatio-temporal scalability support of the proposed video solution is demonstrated in terms of the network adaptation capability.
