DVB publishes requirements for next phase of video codec work

The updates have been published ahead of ETSI's expected update of the DVB-AVC specification

The DVB Project has published two new documents setting out the commercial requirements that will drive the organisation’s next phase of work on video codecs.

The updates have been published ahead of ETSI’s expected update of the DVB-AVC specification.

The documents, DVB BlueBooks C105 and C106, are available for download from the DVB website.

C105: NGVC Phase 2

The DVB Project said the second phase of its work on next-generation video codecs (NGVC) will focus on delivering an enhanced service that is more efficient than simulcast. It would upgrade the base service to a significantly better experience, for example increasing spatial resolution, temporal resolution, bit depth or dynamic range, said the organisation.

BlueBook C015 includes benchmarks to select the appropriate solutions. Targeting broadcast and streaming (DVB-DASH) delivery, solutions should provide the base and enhanced services over the same delivery mechanism, with a 30 per cent bitrate saving over simulcast with existing DVB-AVC codecs.

The target is for the solution to become available at most 12 months after the approval of the commercial requirements.

C106: AV1

The DVB Project has also published commercial requirements for AV1. Finalised in March 2018, AV1 is the first video coding standard developed by the Alliance for Open Media (AOM).

A commercial opportunity has been identified to extend the DVB toolbox’s coverage for internet service delivery through addition of the AV1 codec, it said. The addition of AV1 could increase the flexibility and interoperability of DVB solutions in internet streaming applications given its widespread adoption and deployment across multiple high-volume consumer devices and extensive use by major global internet streaming services.

C106, Commercial Requirements for AV1 addition to the DVB toolbox, outlines support for a variety of streaming applications including video-on-demand, multicast and live linear over broadband, and includes verification and validation requirements.

The work to finalize specifications for a revision of TS 101 154 adding AV1 is already well under way, added the DVB Project.
