PR-SCTP for real time H.264/AVC video streaming

In this paper, we evaluate via real experiments the performance of the Stream Control Transmission Protocol (SCTP) and the Partial Reliability extension (PR-SCTP) for transmitting real-time H.264 video streaming over the Internet. This work looks into ways to apply the partial reliability services of PR-SCTP to exploit the implicit temporal scalability of P and B pictures in H.264/AVC video streams. We develop a simple probabilistic model that allow us to assign a limited number of retransmissions, using PR-SCTP, to each H.264/AVC frame type (e.g. I, P or B) before transmission. With our model we achieve a high probability of frame arrival at the receiver while at the same time keeping a low delay and bandwidth.
