JVET-AO0072 AHG17/AHG18: On ULL evaluation metrics toward CfP [T. Chujoh, Y. Kidani, K. Kawamura (KDDI)]

This contribution reviews the framework for low-latency techniques in previous international video coding standards and discusses evaluation metrics about video coding delay. The purpose of this contribution is to help discussions regarding the testing conditions on ultra-low latency (ULL) in the call for proposals (CfP) on video compression with capability beyond VVC.

It was agreed that requesting such information in CfP submissions would be useful. It was however pointed out that HRD concepts might not apply to some algorithms, or might be wrongly interpreted.

When coded bits per picture are known, many other of the metrics can be determined.

It was asked how different proposals would be compared in terms of the reported metrics? The initial seems to unveil at least the worst case of delay, and if it is exceedingly high.

It was commented that, in the current view of AHG18, processing time for encoding and decoding is not considered.
