Abstract
  • Wireless High Definition Video Transmission (WHDVT) over 802.11-based networks enjoys widespread deployment among today's multimedia solutions. Examples include Intel® Wireless Display and Apple 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. Although current network protocols provide the means to deliver high quality video, they are not always able to maintain smooth video streaming when network conditions deteriorate. This can be attributed to the inability of the network protocol stack to distinguish packets of higher importance contained within a compressed video bitstream. This dissertation explores dynamic methods at the IEEE 802.11 Medium Access Control (MAC) layer and bitstream prioritization at the application and transport layers to improve streaming of H.264 HD video.
