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)]
- 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.

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.
