Compatible HDTV transmission using conditional entropy coding

The authors thoroughly investigate the performance of multistage scalar quantization and investigate three encoding strategies: concatenated coding, conditional entropy coding, and conditional uniform quantization. It is shown that the coding performance of a multistage quantized subband is inferior to that of direct (i.e., single stage) quantization. Conditional entropy coding and conditional uniform quantization partly eliminate this loss.>
