The US military will use digital video compression for many different operations and applications. System requirements result in the need to transmit video streams within limited bandwidth, and often over harsh transmission environments. To deliver video with sufficient quality, the most modern video encoders and decoders (codecs) need to be employed with parameters optimized for high compression...
A variety of techniques have been proposed to enhance the error robustness of the video streaming system. However, most of them improve the error resilience during compression rather than after compression. In this paper, we propose a novel transcoding based scheme called Slepian-Wolf based inter frame transcoding (SWIFT) to improve the error resilience of existing compressed video stream. In the...
This paper evaluates the performance of a zero reference metric used in objective measurement of the quality of video which has been transcoded at various bit rates to suit the needs of the 3G mobile environment. This Zero reference metric (AVQ) has been shown to exhibit a high correlation with Mean Time Between Failures (MTBF) which is a functional measure of video quality representing how often...
