With a total resolution of 7680x4320 pixels, four times the number of pixels per frame compared to 4K/UHD-1, the 8K video format is designed to provide a stronger sensation of reality and a considerably greater immersive experience. 

A key technology component for the success of 8K applications is video compression. High quality 8K video results in huge uncompressed data rates. Advanced video codecs are needed to reduce the data rate while at the same time keeping the quality needed for 8K.

Different video codec standards and formats are currently available from different standardization bodies and industry groups that can, in principle, be used for 8K applications. 

  • Legacy video codecs such as H.264/AVC, although widely accepted, don't have the compression efficiency required for transmitting 8K video content at high quality and low bitrate.
  • Most UHD 4K services are based on HEVC/H.265, and there are several 8K encoders and decoders available for offline and live applications.
  • Beyond HEVC new video codecs have been standardized or proposed as solutions for efficient 8K video content delivery. These include: Versatile Video Coding (VVC), AV1, LCEVC, EVC, and AVS3. And extensions or new versions of some of these codecs are under development.

In this panel we will present the most recent advances in video codecs for 8K delivery and discuss their main capabilities. Compression efficiency (the ability to reduce the bitrate at the same quality) is the main feature of a video codec, but beyond compression efficiency for regular 2D video, other features and applications are becoming important such as: VR/360 video, film-grain synthesis, adaptive streaming, and spatial scalability. Platform and device adoption as well as complexity and energy efficiency are important aspects that will be analyzed as well.
