Paper Abstract

Pyramidal encoding schemes are proposed as an approximation to a subband coding approach into a packet switched transmission environment. In this paper, the method is introduced and justified, extending the classic approach to pyramidal encoding with a pruning mechanism which reduces extensively (in the nearabouts of 3:1) the information to be coded with a very limited quality loss. The different parameters associated to the coding structure are studied, very particularly the behaviour of the input buffer where the subbands are implemented and important delays have to be accounted for. Results are supplied showing the most meaningful design implications that have been found. A detailed description of the simulator which has been developed is also given, expressing with detail the way of handling the asynchrony of the overall process.
