Abstract

Efficient H.264 video transmission, as a dominant video coding standard used in Digital Multimedia Broadcasting (DMB) and other advanced video conferencing, over wireless/mobile networks becomes dominant. However, wireless video transmission suffers from deficient wireless channel conditions such as high bit error rate, error bursts due to channel fading and bandwidth limitations. In this paper, a novel design of unified error-control with cross-layer interaction over IEEE 802.11e Wireless LAN, in order to improve error protection performance, is proposed. This framework combines cross-layer error protection techniques, i.e., error correction code in the link layer, erasure code in the application layer and automatic repeat retransmission across the link layer and the application layer.
