چکیده

Two types of scalabilities exist in current scalable video streaming schemes: (1) nested scalability, in which different representations (i.e., descriptions) of each frame are generated using layered scalable coding and have to be decoded in a fixed sequential order, and (2) parallel scalability, which is used in multiple description coding (MDC) where different descriptions are mutually refinable and independently decodable. In this paper, we present a general framework that includes both scalabilities and demonstrate the similarity between the leaky prediction based layered coding and an MDC scheme that uses motion compensation. Based on this framework, we introduce nested scalability into each description of the MDC stream and propose a fine granularity scalability (FGS) based MDC approach. We also develop a scalable video coding structure that is characterized by the dual-leaky prediction to balance the trade-off between coding efficiency and the error resilience performance of the coded bit stream.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
