JVET-AD0102 Proposed verification test plan for content layering [S. Iwamura, S. Nemoto, A. Ichigaya (NHK)]
This was presented in a joint meeting with AG 5 on Wednesday at 14:00.
This contribution contains an update of a verification test plan of multilayer coding for a content layering use case.
A total of four categories of verification tests are considered for VVC multilayer coding: spatial scalability, quality ladder, content layering, and stereo coding. Content layering is the use case where the main content is encoded as base layer and additional content overlaid on top of the main content, which is called sub-content, is encoded as enhancement layer.
In 28th JVET meeting, it was suggested to conduct a functional test of content layering in the 31st JVET meeting planned in Geneva.
It was commented that this is not a traditional verification test, but rather demonstrating functionality. It was asked if it would be possible to provide a video demo on this functionality on a public site which would demonstrate the effect much more clearly than a paper document. This can be in a compressed format, or contain some copyright protection marks, such that the original content would not publicly provided. The session in Geneva, rather than being an expert viewing for quality, could be done to collect ideas what to demonstrate.
It was commented that much of the functionality shown here could also be done at the systems layer, and it also benefit of doing this in the video layer should be demonstrated or explained.
It was suggested that perhaps more focus should be put on specific functionality possible with video-layer approach.
