VVC, V-PCC standard unlock new frontiers for video, XR, AR
Versatile Video Coding (VVC) shows 50% improvement over HEVC, while Video Point Cloud Compression (V-PCC) enables short-term deployment of immersive AR, XR services.

Mobile and video technology research and development company, InterDigital has announced the finalization of Versatile Video Coding (VVC) and Video-based Point Cloud Compression (V-PCC) video standards at MPEG. The standards bring new capabilities and will enable more interactive experiences within the video ecosystem. The new VVC standard improves high-efficiency video coding (HEVC) performance by 50%, while V-PCC represents the first MPEG compression standard for dynamic point cloud content for immersive video experiences.

A key aspect of VVC is its improved performance over HEVC, which enables the same quality of video at half the bitrate. This characteristic is integral to support the distribution and streaming of increasingly immersive video, especially as video grows to represent more than 80% of internet traffic bandwidth. An improvement upon its predecessors, VVC also supports enhanced features like layered coding, sub-pictures, and adaptive resolution coding which creates an environment for new applications like cloud gaming, immersive and 360°video content distribution, and 8K and High Dynamic Range televisions.

The new V-PCC standard leverages existing video codecs, like HEVC and VVC, to compress high-bandwidth content and enable new services and experiences. Point Clouds are sets of tiny “points” grouped to make a 3D image and have become a popular method for AR and VR video composition, 3D modeling, and geographic mapping. Each Point Cloud video frame typically has hundreds of thousands to millions of points, which translates to a massive amount of bandwidth – typically several Gbps uncompressed. V-PCC can achieve a compression ratio of 300 to 1 for lossy content and thus enables increasingly immersive experiences like AR telepresence, free viewpoint television, and extended reality (XR). Using HEVC as the underlying codec, the compression standard can also be applied to commercially available smartphones.
