  A video-aware unequal loss protection (ULP) system for protecting RTP video
streaming in bursty packet loss networks is proposed. Considering the relevance
of the frame, the state of the channel, and the bitrate constraints of the
protection bitstream, our algorithm selects in real time the most suitable
frames to be protected through forward error protection (FEC) techniques. It
benefits from a wise RTP encapsulation that allows working at a frame level
without requiring any further process than that of parsing RTP headers. This
makes our system straightforward and fast, perfectly suitable to be included in
commercial video streaming servers. Simulation results show how our technique
outperforms other proposed ULP schemes.
