The wireless link poses a significant challenge for sending video streams. This is due to the fact that current generation wireless links have low bit rate and high error rate compared to wire-line links. To send high bit rate delay-sensitive traffic over a wireless link, suitable video compression algorithms and transport/link protocols are needed. We built a wireless video system merging a low bit rate video codec with appropriate transport/link layer protocols that overcome the constraints imposed by the wireless link. In the general case, this project provides a general wireless network infrastructure to support real-time streaming applications. We assume that the application layer provides error resilience, rate control, and packetization functionalities to the network. In turn, the network layers allow error-resilient policies at the application to be reflected in the transport and link layers by enabling flexible checksumming schemes such as UDP Lite and PPP Lite. We evaluated the overall performance of this wireless video system using both quantitative performance metrics (such as throughput, jitter, packet loss, and end-to-end latency) and qualitative performance metrics (such as viewer perception of quality: smooth motion, changes in luminance, edge detection, etc).
