N2 - Constant Bit-Rate (CBR) video is often preferred by broadcasters, as it allows resources to be reserved. This paper applies an adaptive channel coding scheme to CBR video. Compared to some existing schemes advantages include: the coding rate is changed according to the channel conditions; it is byte-based rather than block-based, for reduced latency; and a single retransmission allows a further attempt at reconstruction. The scheme is demonstrated on data-partitioned video, resulting in a number of trade-offs between: frame sequence structure; inclusion of intra-refresh macroblocks; and partition coding isolation. With an appropriate choice of bit-rate reasonable video quality is achieve, including for a temporally active video sequence.
