Abstract :
Media delivery over packet networks is often plagued by packet losses which limit its utility to end users. Forward error correction (FEC) based techniques are important for overcoming this problem. This paper further develops an FEC-based technique to maximize the expected received media quality by jointly choosing which packets to send and which packets to protect - including discarding packets to make additional room for protection. We describe a straight-forward implementation leveraging existing FEC system components. Comprehensive experiments demonstrate that significant gains in PSNR of several dB are achieved when sending H.264/MPEG-4 AVC coded video over a packet erasure channel.
