HDTV Quality Assessment Based on MPEG-2 Video Stream at High Bitrates

摘要：

This paper focuses on HDTV quality assessment based on MPEG-2 streams at high bitrates. Five highdefinition video sequences at four different bitrates (30Mbps, 50Mbps, 70Mbps and 90Mbps) and four highdefinition video sequences compressed repeatedly by multiple times are tested by both subjective and objective experiments. For subjective evaluation, we use double-stimulus continuous quality evaluation (DSCQE). We use PSNR and SSIM algorithms as objective evaluation methods, which are full-reference evaluation methods. The experiment results show that SSIM gives a better performance of quality evaluation on high-definition video streams at high bit rates.
