The DVB Project has updated its video and audio coding specification to include the AVS3 codec.
AVS3, published in October 2021, has been developed by China’s AVS Workgroup. According to the DVB Project, it is capable of encoding video with approximately 40 per cent bitrate savings for the same subjective quality compared to HEVC.
This places AVS3 among the world’s most efficient video coding technologies, said DVB.
The revised DVB-AVC specification includes four conformance points for AVS3, the minimum requirement being a baseline receiver capable of supporting resolutions up to 4K (3840×2160) with HDR.
The three additional conformance points cover the support of high frame rates (HFR), and resolutions up to 8K (7680×4320), said the organisation. The video coding parameters of the four AVS3 conformance points match those of the corresponding four conformance points that were defined for VVC in the previous BlueBook release (A001r19), giving consistency in service levels across codecs, it added.
The DVB said the addition of new codecs enables it to continue to provide the “world’s most comprehensive and flexible” toolbox for the delivery of next generation television services.
