40th Meeting: Geneva, CH, October 2025 2025-10-03 18:03
JVET AHG report: Ultra-low latency and packet loss resilience (AHG18)
Abstract
This document summarizes the activities of AHG18 on ultra-low latency and packet loss resilience between the 39th meeting (Daejeon, KR, 26 June - 04 July 2025) and 40th meeting (Geneva, CH, 03 - 12 October 2025).
JVET-AN0018 JVET AHG report: Ultra-low latency and packet loss resilience (AHG18) [S. Ikonin, S. Wenger, V. Zakharchenko (co-chairs), S. Deshpande, S. Fößel, C. Kim, X. Ma, S. Puri, J. Ström (vice-chairs)]
  1. Activities

The regular JVET e-mail reflector was used for discussions (jvet@lists.rwth-aachen.de). Few organizational e-mails were sent to reflector.

Teleconference

The teleconference was held on August 21st with 27 participants attending.

The following topics were discussed:

  • JVET-AN0046: On test conditions for ultra-low latency and packet loss resilience with full QP range
    • Network bandwidth point selection automation script
    • LDP/LDB simulations in full QP range
    • Spatial Scalability
  • AHG18 software, MRs status
    • MR2: Full VTM
    • MR3: GDR fix
  • JVET-AN0045: Codec software for ultra-low latency and packet loss resilience (related to JVET-AM0218)
    • Software overview
    • Transmission priority model

The meeting minutes are available in JVET-AN0049.

Simulation software

Adoption of last JVET meeting (JVET-AM0203, full VTM support) merged to ‘ull-master’ branch: https://vcgit.hhi.fraunhofer.de/jvet-ahg-ull/VVCSoftware_VTM/-/tree/ull-master. JVET-AM0195 (GDR) is cross-check pending.

  1. Recommendations

The AHG recommended:

  • Review all input contributions.
  • Discuss test conditions and evaluation methodology, taking into account CfE evaluation results.
  • Collect test cases and specific requirements.
  • Continue development of simulation software.
  • Continue the study of ultra-low latency and packet loss resilience technologies in JVET.
