Abstract
This paper proposes an adaptive channel coding scheme for data-partitioned video streaming over a mobile access network, namely IEEE 802.16e (WiMAX). Raptor coding, for reduced latency, is applied at the byte-level rather than the block level. Adaptation is achieved by a single retransmission, when necessary, of extra redundant data to reconstruct corrupted packets. Packet drops are responded to through the error resiliency inherent in partitioned source coding. The paper finds that operation of the proposed scheme depends on: choice of group-of-pictures structure; selection of an appropriate quantization parameter; and configuration of data partitioning to reduce inter-partition dependencies.
