JVET-AN0080 AHG18: CfE response in additional functionality on ultra-low latency and packet loss resilience [S. Ikonin, V. Khamidullin, I. Gribushin, M. Sychev, K. Malyshev, A. Dzugaev, A. Bovsha, X. Ma, E. Alshina (Huawei)]

This contribution describes the coding technology beyond VVC that can be used for ultra-low latency and packet loss resilient decoding scenarios. The described technology re-uses concept of data partitioning of H.263/4, which separates prediction and residual information into different sub-streams. Additionally, entropy coding of residual coefficients is performed using multiple independent entropy coded chunks. A lost aware NN-based filter is further applied to reduce subjective impact of lost residuals and propagation if these errors via inter frame prediction. The evaluation methodology following discussion and contributions of AHG18 is also proposed. According to this methodology the described solution provides average 2.8 dB improvement on top of scalable VTM anchor in broadcast scenario, and freeze rate reduction from 14.7% to 0.4% over single layer VTM anchor in unicast scenario.

NN filter not yet implemented in SADL.

Overhead is counted in NAL units.

It was commented that it might be appropriate to also use channel conditions of other networks.

Data partitioning and entropy coding would need to be normative. NN-based filter might not need to be defined normatively, as it does not change the output in the case of uncorrupted bitstream.

It was commented that a key question would be if all decoders would need to be burdened by tools that are only...

JVET-AN2041 Preliminary Announcement of JVET AHG17 Meeting in Aachen, DE, during 23-27 February 2026 [J.-R. Ohm, M. Wien] (2025-10-27)

Meeting will be hybrid.

Experts requesting for Schengen visa might want to contact J.-R. Ohm and M. Wien as soon as possible.

Future meeting plans, expressions of thanks, a.o.b., and closing of the meeting

The draft of the WG 5 recommendations (see Annex C) was reviewed and approved in JVET at 1030–1100 on Saturday 11 October. In an update discussed on Sunday, the following changes (which had not yet been included in the version that was presented for information in the MPEG WG’s information exchange meeting on Saturday) were approved:

• The following recommendation was deemed necessary to be added: “WG 5 notes that action appears to not yet have been taken on some previous requests for public availability of ISO/IEC deliverables without cost, and kindly requests that ISO/IEC 23008-5:2017 (Ed. 2), ISO/IEC 23008-5:2017/Amd.1:2017, ISO/IEC 23008-8:2018 (Ed. 2), ISO/IEC 23008-8:2018/Amd1:2019, and ISO/IEC 23091-2:2025 (Ed. 3) be made freely available, considering that equivalent publications are freely available elsewhere from ITU-T as editions of ITU-T H.265.2, ITU-T H.265.1, and ITU-T H.273.” Experts were also asked to inform J.-R. Ohm and G. J. Sullivan if relevant standards were missing from this list, as far as they would be expected to be made publicly available.
• The responsible person for delivering 23090-3 is to be changed to Y.K. Wang.
• Some additions are also necessary to the resolutions of thanks, relating to multi-layer testing and...
