JVET-R0364 Information on cinematic aspect ratios in the context of JVET-Q0065 [S. McCarthy, W. Husak, P. Yin, T. Lu, F. Pu, T. Chen (Dolby)]
JVET-Q0065 proposed level constraints on maximum tile size such as to reduce line buffer memory requirements. JVET-Q0065 was adopted at the 17th JVET meeting, Brussels, BE; but further study was suggested regarding some cinematic aspect ratios. This contribution provides information on HD, UHD, and cinematic aspect ratios to resolve that further study. This contribution proposes that the level restrictions adopted in JVET-Q0065 are appropriate and sufficient for standards specifying aspect ratios for HD, UHD, and digital cinema use cases.
This was presented Monday 20 Apr. at 1400 in Track B (chaired by JRO). It was not further discussed in the joint meetings.
It is noted in the contribution that cinematic formats such as CinemaScope which have 2.39:1 aspect ratios are well supported by VVC level definitions.
This contribution was just for information; there was no need for action.
