DS90UB928Q-Q1: 925-928 Video Data mask function

Hi, Team,

When 925 is pared with 928 or such as FPD-LINK III Des,

Is it possible to output "mask" video data from Des? (Something like,,, 1280*720 Video => 925 => 928 => 1280*360 which is cut Upper image)

Or needs to be processed by SoC side?

Thanks,

Koh
