JVET-AL0053 AHG17: Results of expert viewing of non-CTC sequences [M. Wien, A. Wieckowski, K. Andersson]

DCR results which had not yet been readily evaluated during the AHG meeting were presented.

For some UGC sequences, MOS for original is available, which are usually slightly higher than the VTM or ECM at highest rate point (not for all done ). This might be useful to get information in particular if the original has already visible compression artifacts.

Generally, it can be concluded that the DCR test also could work well for UGC content (where however in most cases the “original” quality was quite high)

It was suggested to conduct a comparison of DCR-MOS vs. ACR-MOS.

It was requested to generate a document which includes snapshots of the selected sequences (as per JVET-AL0041), results in terms of MOS, and suggested rate points from JVET-AL0054.
