JVET-AO0071 AHG12: Simplification on TALF [L. Xu, N. Song, Y. Yu, H. Yu, D. Wang (OPPO)]
This contribution proposes to modify the filtering process of TALF to generate the offset without dependency on the output sample of SAO. The number of filter coefficients is reduced by 1. The proposed method is implemented on top of the ECM-19.0 software. The simulation results are summarized as below:
RA: {0.00%, -0.06%, -0.06%, 100%, 100%}
LDB: {-0.04%, 0.22%, 0.11%, 100.1%, 100.0%}

Current ECM-19.0 flow is as follows:
Dependency on SAO output is removed using the following proposed flow, also as a consequence filter tap is reduced by 1:
The proposed method would allow TALF to be performed in parallel to deblocking and BIF/SAO/CCSAO, improving parallelization of the loop filters in...

JVET-AO2041 Announcement of JVET AHG17 Meeting in Aachen, DE, 25-27 February 2026 [J.-R. Ohm, M. Wien] (2026-02-06)
Meeting will be hybrid.
Experts with need to request 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 1630–1645 on Friday 23 January.
Future meeting plans were established with the following general guidelines (assuming face-to-face meetings):
- Meeting under ITU-T SG21 auspices when it meets (ordinarily starting meetings on the Monday, Tuesday or Wednesday of the first week and closing it on the Wednesday of the second week of the SG21 meeting – a total of 8-10 meeting days), and
- Otherwise meeting under ISO/IEC JTC 1/SC 29 auspices when its MPEG WGs meet (ordinarily starting meetings on the Wednesday, Thursday or Friday prior to the main week of such meetings and closing it on the same day as other MPEG WGs – a total of 8–10 meeting days).
In cases where an exceptionally high workload is expected for a meeting, an earlier starting date may be defined, or AHG meetings might be scheduled prior to the meeting. In cases of online meetings, no sessions should be held on weekend days, such that meetings would typically start two days earlier.
Some specific future meeting plans were established as follows:
- During 24 April – 1 May 2026, 42nd meeting under ISO/IEC JTC 1/SC 29 auspices in Santa Eulària, ES, to be conducted as hybrid meeting,
- During 7 – 15 July 2026, 43rd
