1.1.1.1.1.1.1.1.14JCTVC-U0031 Discrepancy between Version 2 text and software for High Throughput Profile [K. Sharman, N. Saunders (Sony)]
(Consideration of this report was chaired by GJS on Wednesday 06-24, 11:30-12:00.)
A discrepancy between the software and the HEVC Version 2 text has been identified that affects the CABAC alignment tool present in the High Throughput profile. This error was first reported on the bug-tracker (ticket #1391), where it has been indicated that the software implements the intended function.
Results are presented to compare the implementation in the standardized text relative to the implementation in the software. The results indicate that the implementation in the standardized text is about 0.05% less efficient in terms of BD-rate for low bit rate conditions, and less than 0.01% increase in BD-rate and bit rates for high bit rate and lossless test conditions.
It was proposed for the JCT-VC to consider whether to amend the software or the standardized text to resolve this discrepancy.
It was suggested that the HM implements the originally-intended design.
Decision: Change the text to match the software.
