JVET-AL0017 JVET AHG report: Testing of video coding technology beyond CTC (AHG17) [M. Wien (chair), E. Alshina, V. Baroncini, P. de Lagrange, Y. Ye (vice chairs)]
Two online AHG calls were held on 2025-02-06 and 2025-03-05, respectively. Furthermore, a hybrid AHG meeting was held at RWTH Aachen University between 2025-03-10 and 03-12. The reports of these meetings are available in JVET-AL0041.
Identification of test sequences and preparation of bitstreams
The set of sequences explored at the previous JVET meeting as well as newly proposed test sequences were encoded and the corresponding RD data and bitstreams were collected in a significant preparatory effort by the volunteers. The test sequences and proposed QP values for the ECM and the VTM were assessed during the hybrid AHG meeting in a number of subjective test sessions.
The discussion and the results of this activity are reported in JVET-AL0041.
Documents JVET-AL0041, JVET-AL0042, JVET-AL0045, JVET-AL0046, JVET-AL0047, JVET-AL0048, JVET-AL0049, and JVET-AL0050 have been initially reviewed in the hybrid AHG meeting. Documents JVET-AL0053 and JVET-AL0054 reflect the results of the testing activity at this meeting.

Recommendations
The AHG recommends:
- To review the remaining input contributions related to AHG17 during the meeting.
- To review the documents JVET-AL0053 and JVET-AL0054 and take their results into consideration for the development of an enhanced draft CfE document.
- To progress the draft CfE document with a proposed set of test categories with respective test sequences.
