Scalable Video Transmission on Overlay Networks
Tien Anh Le, Hang Nguyen, Hongguang Zhang · 2010
Scalable Video Coding is the multi-layer extension of Advanced Video Coding with the advantage of providing visual services for customers with heterogeneous network conditions and terminals' capabilities. In this research, advanced features of Scalable Video Coding are investigated and compared with Advanced Video Coding. A new video transmission evaluation platform is proposed to support the latest Network Abstract Layer Units of Scalable Video Coding. A new interface between the scalable video evaluation platform and an overlay simulation platform is developed so that the transmission performance of Scalable Video Coding bit-streams on an overlay network will be evaluated. Both structural similarity index (SSIM) and peak signal-to-noise ratio (PSNR) measurements are applied to evaluate the performance of the video transmission session. New measurement results are also provided so that other SVC-based service designers can select the right video scalability for their service.
