We study video transcoding for accelerated channel changes in IPTV systems. Video transcoding at the Retransmission Server not only reduces the channel change latency, but also re...
Bit rate adaptation is one of the most important types of video transcoding. With H.264 becoming the predominant video codec of choice in video coding and streaming, prudent ratea...
Approximately 2 degrees in our 140 degree vision span has sharp vision. Many researchers have been fascinated by the idea of eyetracking integrated perceptual compression of an im...
In network delivery of digital video, if the bandwidth required for a video is not available, the video has to be recoded at a reduced bit rate. It is highly desirable that the tr...
— In this paper, we present a two-pass error-resilience transcoding scheme based on content-aware intra-refresh (CAIR) for inserting error-resilience features to a compressed vid...
