JVET-Y0099 VVC level 4.2 [G. Martin-Cocher (InterDigital)]
This contribution proposes to discuss whether a VVC level 4.2 is needed to address use-cases such as Cloud/Online Gaming as results on some non-CTC 1080p sequences indicates that a bit rate above the main and high tier limit is reached. It may be desirable to rely on a “Main Tier” to address this use-case rather than on a “high tier”.
It was pointed out that the proposal would have the problem that level 5.0 Main tier would not be capable to decode the proposed 4.2 Main tier. A possible solution would be to change the max bit rate in main tier from 50000 to 25000, and changing High tier from 75000 to 100000. This would be the same bit rate as 5.0, but smaller picture size.
Several concerns were expressed about whether such a new level is needed or would be used practically. Further evidence was sought.
