Abstract
A channel code allocation scheme is developed for transmission of
video over error-prone channels.
The system is designed to minimize the expected distortion of the video
under a quality constraint.
It is based on the Viterbi algorithm and achieves a very robust bit stream, also in mismatch
situations.
It is further shown that the distribution of available channel codes varies
significantly with respect to the channel conditions.
