Abstract :
The motion-compensated embedded zero block coding (MC-EZBC) is a wavelet-based video coding scheme using motion-compensated temporal filtering (MCTF) and spatial sub band bit plane zero block coding (EZBC) to offer embedded scalable bit stream in terms of spatial resolution, frame rate, and SNR quality. However, the typical MC-EZBC bit stream structure makes it only suitable for storage video transmission. We propose an improved MC-EZBC bit stream structure for live video streaming, and design some simple and lightweight algorithms for MC-EZBC sub stream extraction in bit stream domain.
