Abstract :
This paper presents a joint source channel coding designed for video transmission application. The aim is to improve the visual quality of the reconstructed video even when transmission errors occur while keeping 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) optimally mapped on a QAM-M modulation. The whole of the transmission chain is jointly exploited in order to make it well-adapted to the complex and low data rate channel.
