Contemporary Video Compression Standards. H.265/HEVC, VP9, VP10, Daala

In this paper we compare compression efficiency of the latest video coding standards H.265/HEVC, VP9, VP10 and Daala to H.264/AVC with the help of reference video encoders available.

This blog post deliberates on the results published in our research paper:
Sharabayko M.P., Markov N.G. Contemporary Video Compression Standards. H.265/HEVC, VP9, VP10, Daala. Control and Communications (SIBCON), 2016 International Siberian Conference on, Moscow, 12-14 May, 2016, pp. 1-4.

Xiph's Daala Compression Efficiency Update

Nine months have passed since my last comparisson of the HEVC, VP9 and Daala compression efficiency. Daala was in the development stage and is still being developed. Recently I've updated the codec to see the changes.
My apologies to the haters of PSNR and the lovers of SSIM. I'm still using PSNR.

Next Generation Video Codecs: HEVC, VP9, Daala

Nowadays video services (digital television, Internet video etc.) are a common part of our live. According to Cisco [1] mobile video traffic was 51 percent of the entire global Internet traffic by the end of 2012 and it is expected to be 66 percent by 2017.
The demand on video and its quality is very high. Since the appearance of VoIP in 1984 video resolution has increased from QCIF (176×144 pixels) to Full HD (1920×1080). Now it is evolving to 4K (3840×2160) and 8K (7680×4320) UHD. But the higher the resolution and quality is, the higher bitrate it takes.
This paper contains a general review of new video compression standards HEVC, VP9 and Daala. Their compression efficiency is studied and compared to AVC.
The paper was reported at the XI International Theoretical and Practical Conference of Students and Young Scientists "Youth and Contemporary Information Technolodies". The report can be found here.
