Abstract :
The simple automatic repeat request (ARQ) scheme, error concealment by command refreshment, appropriate queuing discipline and priority switching design, layered source coding schemes, and other signal processing techniques are summarized with emphasis on different layered source coding schemes. Four types of signal priority classification schemes are identified: bit-plane separation (BPS), frequency-domain separation (FDS), combined bit-plane-frequency separation (CBFS) and feature plane separation (FPS). CBFS is shown to offer a good alternative to the FDS for possible cell dropping compensations in the ATM network. Different layered source coding schemes are described and compared, and a CBFS-based combined-transform coding (CTC) scheme is highlighted
