COMSOC Talk: Advanced Video Compression: Standards and Applications
Ofer Hadar, Ben-Gurion University of the Negev, Israel

About the Talk Nowadays, we cannot imagine our life without video content and without devices that enable us to acquire and display such content. According to recent 2012 research, the video content transfer over the Internet was around 60% of the overall Internet data transfer, and the overall video transfer (including the Internet) could reach 90% during the next four years. TV sets supporting only full high-definition (HD) resolution (i.e., 1080p) are already considered to be outdated due to a dramatic demand for the ultra-HD resolution that often refers to 3840×2160 (4K) or 7680×4320 (8K) resolutions. In this talk, we will provide an overview of recent achievements in video compression technology including some results of our research group. The talk will start with motivation for video compression and a short introduction of the video compression standards history followed by the description of the current H.264/MPEG-4 AVC video coding standard. Then, we will describe the scalable video coding (SVC) standard in H.264. The last part of the talk will present the most recent high-efficiency video coding (HEVC) standard, which is capable of providing a bit-rate reduction of about 50% at the same visual quality compared to its predecessor. We will compare between HEVC, H.264 and VP9 (Google standard for video compression) that have been presented recently in PCS2013. The talk will conclude with some future directions in video compression.
