JVET-AO0153 AHG 12/17: On EIP in JVET-AN0267 software [Z. Xie, L. Xu, Y. Yu, H. Yu, D. Wang (OPPO)]
This contribution reports the tool-on results of EIP using the JVET-AN0267 software. In addition, more tests were carried out, including modification to the EIP regularization, removal of the EIP fast algorithm and addition of BV-EIP. The test conditions follow the CTC of ECM, where QPs {22, 27, 32, 37}, all-intra and random-access configurations were used. The anchor is JVET-AN0267 and results are summarized as below:
Test 1: EIP tool-on test
All-intra: -0.15% (Y), -0.03% (U), -0.10% (V), 108.0% (EncT), 103.4% (DecT)
Random-access: -0.08% (Y), -0.20% (U), -0.08% (V), 101.7% (EncT), 99.5% (DecT)
Test 2: EIP regularization modification
All-intra: -0.37% (Y), -0.30% (U), -0.38% (V), 107.9% (EncT), 104.6% (DecT)
Random-access: -0.15% (Y), -0.13% (U), -0.24% (V), 102.1% (EncT), 100.2% (DecT)
Test 3: Test 2 + removal of EIP fast algorithm
All-intra: -0.40% (Y), -0.31% (U), -0.39% (V), 109.5% (EncT), 105.0% (DecT)
Random-access: -0.12% (Y), -0.27% (U), -0.11% (V), 102.2% (EncT), 100.3% (DecT)
Test 4: Test 3 + BV-EIP
All-intra: -0.48% (Y), -0.38% (U), -0.45% (V), 110.0% (EncT), 105.4% (DecT)
Random-access: -0.14% (Y), -0.18% (U), -0.24% (V), 101.6% (EncT), 99.9% (DecT)

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
JVET-AO0012 JVET AHG report: Enhanced compression beyond VVC capability (AHG12) [M. Karczewicz, Y. Ye, L. Zhang (co-chairs), B. Bross, R. Chernyak, X. Li, K. Naser, Y. Yu (vice-chairs)]
Activities
The primary activity of the AHG was the “Exploration experiment on enhanced compression beyond VVC capability” (JVET-AN2024). The combined improvements of the ECM-19.0 over VTM-11.0ecm19.0 anchor for AI, RA and LB configurations are:
