VPSS get BT.656 data format

Kuve Ma

Dear sirs,

As the discussion, http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/120477.aspx, DM8148 VIN[0] and VIN[1] can support BT656.

I use VPSS examle code and get trouble several weeks.

I want to input BT656 data(OV10630) to VIN[0] portB base on HDVPSS_01_00_01_28\packages\ti\psp\examples\common\vps\chains and change VIP setting(in chains_tvp5158NonMuxCapture.c) and mark #define SYSTEM_USE_VIDEO_DECODER(in system.h)

It isn't working. Somebody can give me some instruction or hint about decoding BT656.

Thank you,

Kuve

Hi,

May I confirm HDVPSS capture port could decode BT.656 for OV10630 image sensor?

It mean I don't connect OV10630's VSYNC and HSYNC pin to DM8148 video port.

If you know something, please give me a hand. Thank you very match.

It is work and sensor should cooperate with capture port.

I only focus on VIP setting.
