Abstract
This work proposes an adaptive unequal error protection (UEP) and packet size assignment scheme for scalable video transmission over a burst-error channel. An analytic model is developed to evaluate the impact of channel bit error rate on the quality of streaming scalable video. A video transmission scheme, which combines the adaptive assignment of packet size with unequal error protection to increase the end-to-end video quality, is proposed. Several distinct scalable video transmission schemes over burst-error channel have been compared, and the simulation results reveal that the proposed transmission schemes can react to varying channel conditions with less and smoother quality degradation.
Highlights
Bit errors and packet losses are common throughout the wired/wireless Internet
(i) Frame resolution = CIF format − 352 × 288 pixels. (ii) Constant stream rate = 256 Kbps. (iii) 1 group of pictures (GOP) = 1 intraframe accompanied with interframes, and frame rate = fps. (iv) Sequence length = 9 GOPs. (v) MPEG-4 fine granular scalability (FGS) method is adopted to generate scalable video streams
Comparing the performance of the proposed approaches shows that the AUEP + adaptive packet size (APS) scheme outperforms all the others
Summary
Bit errors and packet losses are common throughout the wired/wireless Internet. They severely influence the quality of delay-sensitive multimedia applications. In [20], a dynamic packet size mechanism in wireless networks was proposed, but the problems associated with burst-error channel and the adaptation of video quality have not been addressed. This work investigates a video transmission scheme, which combines a scalable video coder with unequal error protection (UEP) and adaptive packet size (APS) assignment, to cope with the sometimes rapidly varying transmission conditions over wired or wireless Internet connections.
