Abstract

This paper presents a joint source channel coding designed for video (sequences of images) transmission application. The aim is to improve the visual quality of the reconstructed video, even when transmission errors occur, and to keep the processing as simple as possible. The BER excepted is higher than 10^-4. This coding is based on an association of a wavelet transform (WT) and a vector quantization (VQ). The whole transmission chain is jointly exploited in order to make it well-adapted to the complex and low data rate channel.
