FGS 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...

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...

HYBRID FUNCTIONS APPROACH AND PIECEWISE CONSTANT FUNCTION BY COLLOCATION METHOD FOR THE NONLINEAR VOLTERRA-FREDHOLM INTEGRAL EQUATIONS

In this work, we will compare two approximation method based on hybrid Legendre andBlock-Pulse functions and a computational method for solving nonlinear Fredholm-Volterraintegral equations of the second kind which is based on replacement of the unknown functionby truncated series of well known Block-Pulse functions (BPfs) expansion

Predicting the Efficiency of Decision-Making Unit by Using Piecewise Polynomial Extrapolation in Different Times

In this article, we will estimate efficiency amountof decision-making unit by offering the continuous piecewise polynomialextrapolation and interpolation by CCR model input-oriented on the assumptionthat it is constant returns to scale in different times. And finally, we willestimate efficiency amount of decision-making unit indifferent times byoffering an example.
