An Efficient Adaptive Layer Switching Algorithm for Video Transmission over Link- Adaptive Networks

Veerabhadrayya Math, Mr. Sai Venkatramana Prasada G. S.

In the last few years, it has become feasible to provide high-quality digital video over different channel qualities. This paper presents an efficient adaptive layer switching algorithm for scalable video transmission over link adaptive networks. This algorithm is effective at the receiver end of the video transmission for adapting the video bitrate to match the achievable network throughput. A very important aspect of this algorithm is providing a QoS confine equivalent bandwidth estimator employed at the receiver, which is used for triggering the adjustment of video layers at the video source. The average Peak Signal-to-Noise ratio (PSNR) and Frame Dropping Ratio (FDR) are used for characterizing the performance of the proposed method. Simulations are conducted on MATLAB to illustrate its efficiency by showing that it is capable of accommodating different channel qualities without their prior knowledge.
