Abstract

Wireless High Definition Video Transmission (WHDVT) over 802.11-based networks enjoys widespread deployment among today's multimedia solutions. Examples include Intel's WiDi™and Apple's Airplay™, to name a few. In these systems, peer-to-peer networks are established over which H.264-encoded video is transported wirelessly to be decoded and played back at the receiving node. Built-in reliability at the IEEE 802.11 Medium Access Control (MAC) layer retransmits lost packets up to a default number of retries. Excessive delay induced by such retransmissions can violate the tight playout deadlines for HD content. Furthermore, lower priority packets may be delivered at the expense of delaying other packets of higher visual impact on the displayed video. To mitigate this problem, this paper proposes Dynamic Retry Adaptation Scheme (DRAS.264) tailored to today's compression standard of choice--the H.264/AVC codec. DRAS.264 parses H.264 bitstreams on-the-fly to dynamically adjust retransmission limits at the MAC layer. Simulation results show significant PSNR improvements (over 10 dBs) for stretches of received video under DRAS.264 over the default MAC layer operation.
