JVET-D0165 Cross-check of JVET-D0098 Decoupling decoder-side intra mode derivation from entropy decoding [Alexey Filippov, Vasily Rufitskiy, Haitao Yang (Huawei)] [late]

EE9: Adaptive Scaling for Extended Colour Volume (2)

Primary (2)

From summary report JVET-D0010:

This experiment studies an alternative to the residual scaling proposed in JVET-B0054. The motivation in JVET-B0054 is to remove the overhead of delta QP that is signalled by the encoder to compensate for the reshaping of quantization noise as a function of brightness in next generation containers such as ST 2084.

Questions recommended to be answered during EE tests:

[Q]: What is performance of JVET-C0066, JVET-C0095 and JVET-C0102 using the content and test conditions provided by the AhG 7 on JEM coding of extended colour material with:

• Results reported with the weighted BD-Rate and BD-PSNR metrics, where the weighting corresponds to the target luma-to-QP mapping function.
• Results reported with BD-Rate and BD-PSNR for the tPNSRY and deltaE metrics, where the metrics are computed from linear RGB
• Results reported for visual quality assessment

[A]: Only partial data available.

[Q]: What is the benefit of combining different aspects of the JVET-C0066, JVET-C0095 and JVET-C0102?

[A]: Not answered yet.

Conclusion from EE summary: The test procedure should be agreed first. AhG7 was discussing testing procedure.

BoG (coordinated by A. Segall) recommendation: Review EE results, and agree conversion method and test procedure

See further discussion under JVET-D0192: Both proposals are to be further investigated in new EE6.

A draft of this document was presented to the plenary Thursday afternoon. During the closing plenary on Friday, the document was approved without further review; no experts had complaints about the procedure.

It was reminded that in cases where a JVET document is also made available as an MPEG output document, a separate version under the MPEG document header should also be generated. This version should be sent to GJS and JRO for review and upload.
