Vertical Handoff Algorithms for Heterogeneous 3G Networks

Abstract

This paper compares the video quality performance of low definition (LD), standard definition (SD) and high definition (HD) video signals encoded with H.264/AVC and Dirac using full-reference (PSNR and SSIM) and no-reference metrics (JPEG-NR) for different bit rates. It is shown that H.264 outperforms Dirac concerning quality for all resolutions.
