Abstract :
Multiresolution transmission of compressed video is performed using subbands. Multistage quantization is necessary for efficient embedded video transmission on rate constrained channels. This paper investigates the performance of a number of multistage scalar quantization techniques: concatenated coding, conditional entropy coding and conditional quantization. Intraframe as well as interframe coding approaches are investigated with these multistage quantization techniques on high definition and standard definition source material
