Abstract

This chapter provides an overview of joint source-channel coding and decoding. We first address joint decoding techniques, which exploit the residual redundancy left by source coders in the compressed data stream to correct transmission impairments. Combined with concealment, these techniques may reduce the need for packet retransmissions when they are allowed. Then, this chapter introduces joint source-channel coding. Several joint coding techniques are presented, ranging from redundant signal representations via frames, correlating transforms, or channel codes, ...
