Hello All,
I use TVP7002 register - clocks per line(39h-3Ah) and lines per frame(37h-38h) to detect what video standard have been capture. And set the related parameters of TVP7002 registers.
It's ok for most of VESA video standard!
But in 1280x768@60 and 1366x768@60, it cant distinguish.
clocks per line: 136
lines per frame: 798
It almost the same.
How can I distinguish?
BTW, I am capturing the VGA source(RGB, VESA standard) and output the 20bit 4:2:2 format embedded sync.
Thanks!!
Regards,
Steven
