An Adaptive Periodic FEC Scheme for Internet Video Applications

When transmitting packets compressed with a high compression standard such as MPEG or H.261, the loss of single packet has a considerable effect on the following frames because of motion estimation and compensation. There are many techniques that prevent this error propagation. We classify the video error control techniques into codec-level and network-level schemes and investigate the effect of various combinations. As the result, we propose a new FEC-based video error control scheme, Periodic FEC, which provides error resilience, adaptability to network conditions and the ability to combine with other scheme. Through experiments, it is confirmed that the Periodic FEC scheme is superior to other schemes such as FEC, RPS etc, and the performance of this scheme can be maximized when combined with other schemes.
