37th Meeting: Geneva, CH, January 2025 2025-01-20 17:38
Abstract
This contribution presents a summary of a gap analysis carried out with respect to existing MPEG/VCEG video coding standards. The contribution also provides suggestions for updates of “Preliminary draft of use cases and requirements for potential next-generation video coding standard beyond VVC capability” based on the gap analysis.
JVET-AK0338 Gap analysis and suggested updates to next-generation video coding requirements draft [J. Samuelsson-Allendes, S. Deshpande, T. Ikai (Sharp)] [late]

It was suggested to establish a joint AHG with the following mandates:

  • Consider and summarize input from workshop
  • Suggest refinements of draft requirements
  • Review m71221, m71598 (also available as JVET)
  • Collect and study additional contributions on requirements (to be provided to both orgs)

Mary-Luc Champel (a WG 2 member from Xiaomi) and Justin Ridge (an SG21 vice chair and WP3/21 co-chair, Nokia/USA) were planned to be the co-chairs of this AHG, which was agreed could hold teleconference meetings (with at least two weeks advance notice).

This was agreed in the joint meeting, but it was not reflected in the AHG plans established in the meeting recommendations of MPEG WG2 (apparently by accident). WG 2 did establish an “AhG on MPEG Use Cases and Requirements” with Champel and Igor Curcio (the WG 2 Convenor from Nokia) as co-chairs. In practice, collaboration during the interim period can take place with a less formalized relationship.

It was agreed that JVET would issue a “draft experiment on non-CTC” testing, but would not issue a document with the title “CfE” from the current meeting.

Abstract
This contribution proposes some changes on top of the error recovery SEI message that is proposed in JVET-AL0069. The proposed changes are for incorporating temporal sub layers into the signalling of the proposed error recovery SEI message. It is asserted that the support for temporal sub layers is desirable as with it the error recovery SEI message allows encoder to use better reference pictures in the event of picture loss during transmission.
