Omnidirectional 360° Video Coding Technology in Responses to the Joint Call for Proposals on Video Compression With Capability Beyond HEVC
Augmented reality (AR) and virtual reality (VR) applications have seen rising popularity in recent years. Omnidirectional 360° video is a video format often used in AR and VR applications.

| description | Augmented reality (AR) and virtual reality (VR) applications have seen rising popularity in recent years. Omnidirectional 360° video is a video format often used in AR and VR applications. To address the industry needs, a new HEVC edition recently published includes several supplemental enhancement information (SEI) messages to enable the carriage of omnidirectional video using HEVC. However, further improvement in 360° video compression efficiency is needed. In order to address this challenge, the Joint Video Exploration Team (JVET) of ITU-T VCEG and ISO/IEC MPEG has been investigating 360° video coding technologies, including projection formats, pre- and post-processing technologies, as well as 360°-video-specific coding tools since 2016. The joint call for proposals (CfP) recently issued by ITU-T VCEG and ISO/IEC MPEG on video compression technologies beyond HEVC included a category on 360° video. Twelve CfP responses in the 360° video category were received. This paper describes technologies relevant to 360° video for VVC. A summary of projection formats, pre- and post-processing methods, and 360°-video specific coding tool modifications in these proposals is provided. |
