Progressive texture video coding

We present a novel video coding approach which provides the functionality of fine granular bitstream scalability. The proposed progressive texture video coding (PTVC) scheme consists of two parts: the current ITU-T H.26L test model for coding macroblock mode and motion information only; a new technique for progressively coding all intra and inter texture information thus providing an embedded bitstream. It can still be decoded with moderate quality degradation in case of partial loss of the bitstream. It is therefore well suited for multicast or broadcast scenarios where time varying or different fixed bitrates are provided to the clients, as no transcoding or multiple coding process is required
