ADV212 Compression Time

The ADV212's compression time is described as ~1.5x the "frame time".  For raw mode, is this equivalent to the amount of time it takes to input the image?


Also -- is the compression time actually tied to the input time, or is it instead tied to the ideal/fastest input time?  If we choose HDATA (max of 34MSPS input rate) rather than VDATA (max of 48MSPS), for instance, does the compression time slow down?  If we use VDATA at 40MHz instead of the max of 48MHz, does the compression time slow down?


Finally, is that compression time in addition to the time it takes to load in the video or does it include that time? (i.e. if I spend 5ms feeding the data in via vData, will it be ready ~7.5ms after I started feeding data, or ~7.5ms after I finished feeding data)
