1. An improved method of joint source-channel coding, wherein the joint source-channel coding sequentially processes source video to be compressed in a source encoder stage, a channel encoder stage and a rate controller stage to produce a joint source-channel coded bitstream, the improvement comprising:
- determining a change in at least one of a transmission bandwidth parameter and a transmission error rate parameter;
changing the process of at least one of the source encoder stage, the channel encoder stage and the rate control stage in response to the at least one determined change.
