ABSTRACT
In this paper, we propose a transrating based video rate adaptation
technique for compressed high-definition video transmission over
wireless local area networks. Our application layer technique targets
to prevent the quality impairments caused by inconsistent wireless
bandwidth. The transrater at the server adjusts the transmission
rate for each video frame, based on bandwidth measurements,
to sustain the playout buffer fullness. Client periodically sends
feedbacks after probing the available bandwidth using the video
