摘要

提出了一种用于视频传输的联合信源信道编码方法。其目的是提高重建视频的视觉质量，即使在传输错误发生的情况下，同时保持处理尽可能简单。例外的误码率大于10-4。这种编码是基于小波变换(WT)和矢量量化(VQ)的关联，最佳映射在QAM-M调制上。整个传输链被联合开发，以使其能够很好地适应复杂和低数据速率的信道。

A joint source channel coding strategy for video transmission

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.
