Constant quality rate control for streaming MPEG-4 FGS video
This paper presents a constant quality video rate control (CQVRC) scheme for MPEG-4 FGS (fine-grain scalability) video. The proposed scheme can mitigate quality variations among consecutive frames during the period when there is significant change in the video source or the transmission bandwidth. CQVRC utilizes both non-scalable base layer (BL) and scalable enhancement layer (EL) of MPEG-4 for...
متن کاملFGS MPEG-4 Video Streaming with Constant-Quality Rate Adaptation, Prioritized Packetization and Di erentiated Forward
A video streaming solution with the ner granular scalable (FGS) MPEG-4 stream delivered over prioritized networks is investigated in this work. An optimal truncation strategy for constant-quality rate adaptation is rst presented by embedding the rate-distortion (R-D) information based on a piecewise linear R-D model. Then, the video stream is prioritized for di erentiated dropping and forwardin...
متن کاملImplementation of adaptive streaming of stored MPEG-4 FGS video over TCP
This paper presents an implementation of an end-to-end application for streaming stored MPEG-4 Fine-Grained Scalable (FGS) videos over the best-effort Internet. Our current implementation runs over TCP but can also be run over TCPfriendly RTP/UDP with an error recovery mechanism. Our scheme adapts the coding rate of the streaming video to the variations of the available bandwidth for the connec...
متن کاملMPEG-4 FGS video streaming with constant-quality rate control and differentiated forwarding
Streaming video over IP is studied by integrating the error resilient scalable source codec with constant quality rate adaptation and prioritized network transmission. The scalable codec is based on the standardized ISO/IEC MPEG-4 fine granular scalable (FGS) coding scheme, which allows arbitrary truncation according to the given rate budget. To maximize the end-to-end visual quality, constant ...
متن کاملRate Allocation of Equal Image Quality for MPEG-4 FGS Video Streaming
This paper proposes a new rate allocation method for MPEG-4 fine granularity scalable (FGS) video streaming, with which the received image quality can be smoothed during the streaming period. Although average bit rate allocation is quite simple, the image’s quality changes greatly between frames, which will result in quality fluctuation and degrade the streaming quality. In this paper the bits ...
