data to remember

For 60fps video, it takes 16.668333ms for each frame. 720×480, 28 ((1 / 16.668333 ) * 480) = 28 ) lines are transferred per ms. Practically, the lines are more than this number, as 16.668333 counts all the time, including the time for sync signals. What I saw is around 16ms (16.1, or 16.2, might be 16, or even a few us shorter than 16ms ).
