Multiplexing video streams using dual-frame video coding (original) (raw)

2008

Abstract

We consider the transmission of multiple video source streams over a shared channel from a server. Using the rate-distortion curves and dual-frame video coding with high quality long-term reference (LTR) frames, we propose a method to reduce the sum of mean squared error for all the video streams. A simple motion activity detection algorithm was used to determine the amount of high quality given to the LTR frames. Using H.264/AVC, the results show considerable improvement over a baseline scheme where each video stream is provided with equal bitrate.
