DVB has approved commercial requirements for next generation video codecs ahead of the launch of advanced 4K and 8K services.
The Geneva-based body will now begin an investigation into the commercial requirements and to develop draft specifications. The compliance of the proposed solutions with the IPR policy of the DVB Project is also being examined.
The three candidate codecs that have been initially identified as candidates for inclusion are AV1, AVS3 and VVC. The three codecs can potentially extend the market reach of DVB solutions and bring new features and efficiencies.
“DVB is a pioneer in the development of media distribution systems and it is preparing the way for advanced 4K and 8K systems in the future” said Peter MacAvock, Chair of the DVB Project. “The industry is watching our work closely and we are confident that DVB will again break new ground on television technology. We encourage all companies with a stake in this field to join our work.”
By specifying how to use next generation video codecs, DVB hopes to enable new video experiences such as 8K, as well as improved accessibility and personalisation options. The greater efficiency promised by the new codecs will help enable an increased UHD service offer on terrestrial broadcast networks and greater reach coupled with lower distribution costs for broadband delivery.
Support for 8K video is one of the key requirements defined, with resolution up to 7680×4320 pixels. High dynamic range (HDR) and high frame rates (HFR) are also to be supported.
To improve delivery models for 4K video, it is required that new codecs provide a data-rate saving of at least 27% compared to the existing HEVC codec in 4K broadcast applications, and of at least 30% for 4K in broadband applications.
The first specifications will be available in 2022.
