An Optimal Unequal Frame Protection Scheme in Video Streaming

Following with the advancements in digitization technology and broadband communication technology, video streaming service has become an essential one for next generation Internet. When transmitting compressed video frames across the Internet, however, one of the main challenges is packet error/loss. High coding dependencies among video frames suffer from vulnerability to packet loss, which impacts the playback quality. Losing an important frame may cause a set of frames loss or damage as well. In this paper, we investigate different mechanism to decide video frames important level. According to the frame important level, we formulate the unequal frame protection (UEP) problem into optimal resource allocation problem to maximize the playback quality in client. The simulation results reveal that the proposed optimal resource allocation has better performance improvement than other frame protection schemes in term of playback quality under different bit error rate.
