METHOD AND SYSTEM FOR PERFORMING RATE CONTROL ADAPTED TO CHANNEL CONDITIONS

摘要

A method and system for determining in real time the instantaneous output rate of a low delay video frame encoder/application for encoding a video frame to be transmitted are disclosed. The video frame encoder provides its output for wireless transmission over a telecommunication channel. In one aspect, a method comprises providing an estimate of the instantaneous channel conditions under which the video frame will be transmitted. The method further comprises determining the instantaneous output rate by selecting a high output rate when the channel conditions considered acceptable and selecting a low output rate when the channel conditions are considered unacceptable.
