Multilayered resolution based coding for Internet video streaming

Abstract

Video streaming over the internet without buffering is a challenging task. The requirements in this field actually include an almost lossless compression of video to be provided to the customer with a minimum bandwidth. In order to maintain a continuous flow of video without any disconnection or large buffering at the receiver, a new algorithm called the Multi-Layered Resolution based Coding with Cross Layer Adaptation (MLRC-CLA) algorithm is proposed in this paper. The input video is coded at different levels of resolution and stored at the video hosting site. The MLRC-CLA algorithm gradually selects the appropriate resolution for the viewer based on the viewer's network bandwidth and sends that particular resolution the viewer. The parameter used in this paper is Peek-Signal to Noise ratio (PSNR).
