Abstract

We propose an adaptive unequal error protection scheme to help protect a video stream over the Internet. The data partition approach and the resynchronization marker are applied to generate two types of packets with different importance. Our scheme is very adaptive to network traffic conditions and can be easily implemented via software. With the proposed scheme, more protection is provided for the more important packets. The final quality can therefore be improved at a higher packet loss ratio.
