The Decision Scheme of Frame Importance Factor for Video Streaming System

Following with the advancements in digitization technology and broadband communication technology, real-time video streaming service has become an essential one for next generation Internet. When transmitting compressed video 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 of video streaming. Losing an frame importance may cause a set of frames loss or damage as well. In this paper, we propose an effective important frame decision scheme in which the playback quality is considered. The results of this paper can be applied to the unequal frame protection scheme which targets to improve the video playback quality with minimal frame protection overhead.
