JVET-AL0018 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)]
The repository for AHG related simulation software was established, and can be accessed at: https://vcgit.hhi.fraunhofer.de/jvet-ahg-ull/VVCSoftware_VTM.
Teleconferences
Two teleconferences were held on February 19th and March 14th, with 51 and 26 participant correspondingly.
The following topics were discussed:
- VTM + network model simulation software introduction.
- Network bandwidth simulation point introduction.
- Transmission latency derivation logic based on end-to-end latency.
- ULL metrics calculation example and correspondent excel template.
- Scalable transmission scenario simulation example.
- No-feedback IPPI-based transmission scenario example.
- Latency calculation consistency fix, and list of other modifications.
The meeting minutes, presented materials and video demonstrations are available in JVET-AL0044.

- Recommendations
The AHG recommends:
- Review all input contributions.
- Discuss test conditions and evaluation methodology.
- 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.
It was suggested to make the software available to all JVET experts.
