Internet video using error resilient scalable compression and cooperative transport protocol

We introduce a point to point video transmission scheme over the Internet combining a low-delay TCP-friendly transport protocol in conjunction with a novel, real time, error-resilient layered compression method. Compressed video is packetized into individually decodable packets that are of equal expected visual importance. As a result, relatively constant video quality can be achieved at the receiver under lossy conditions. The packets can be truncated to meet the time varying bandwidth imposed by the transport protocol. Actual Internet experiments together with simulations are used to evaluate the performance of the combined scheme.
