An adaptive protection framework for MPEG base layer video streaming over Internet

Video streaming over the Internet or wireless environment is an imperative application. However, packetized video frames suffer from random losses when they are streamed over the Internet. Packet losses degrade video quality, even if applications adopt error resilience techniques. To provide more guaranteed video quality, we re-investigate the PET system (Albanese et al., November 1996) and propose an adaptive optimization-based protection assignment framework based on PET for streaming MPEG base layer video under a given bandwidth constraint Our framework incorporates considerations of both the variant bandwidth issue and the packet loss issue on the Internet. The results of our experiments demonstrate our proposed framework achieves the goal of adaptive optimization assignment for MPEG video streaming.
