Capture / Encode PAL and NTSC video formats simultaneously

Other Parts Discussed in Thread: TVP5158

Hi All,

Can VIN0_B be configured to capture a mixture of both PAL and NTSC video formats simultaneously? Our configuration:

TVP5158 Source (8-bit quad interleaved YCbCr, 4xNTSC or PAL @ 108MHz) -> VIN0_B -> Capture -> DEI -> Merge -> Enc -> A8 -> Ethernet

We are using a custom board running the DVRRDK_04.01.00.02 referece software. I am currently able to encode all as NTSC resolution or all as PAL resolution (using isPalMode capture parameter). But, if I have a single PAL and 3xNTSC then I get either the lower 96 lines of PAL missing or be left with 96 extra lines for the NTSC video.

Ideally I'd like to dynamically set the input resolution of the individual multiplexed channels. Using the existing capture McFW calls, I am able to change the output resolution of the video to the desired resolution, but fails to crop the video properly. Any suggestions?

Thanks!

Jason
