Abstract

In this paper 3 is presented an adaptive video compression algorithm designed for the video transmission over best-effort network with services that can adapt to changing network conditions, specifically Available Bit Rate (ABR) services in Asynchronous Transfer Mode (ATM) networks.

The proposed algorithm tries to minimise the impact that cell losses could have on the perceived quality, using perceptual bit allocation procedures and Rate-Distortion minimisation techniques. Furthermore the algorithm adaptively estimates the compression ratio by means of a forecast mechanism based on the value of the feedback signal sent by the network. It should be noticed this algorithm is based on a 3D subband coding that uses wavelet filter banks but it does not use motion estimation with block matching procedures to prevent from error propagation effects.
