Can we access RAW VBI Data on Dm368 Platform?

Other Parts Discussed in Thread: TVP5147

Hi,

 We have a custom board sporting a dm368 connected to a TVP5147 outputting BT.656 with embedded syncs.

We would like to push some data up from a custom camera head during Vertical blanking using the TVP's Raw VBI mode.

I have configured the TVP for Raw VBI, but see no way on the dm368 side to access this data.

We get two interrupts per frame for bt.656 using embedded sync, and I presume the interrupts only occur on EAV for the two fields of video and the VBI portion is just discarded before it reaches SDRAM.

I hope I'm wrong.

Is there any way to access the raw VBI data pushed from the TVP5147?

Thanks

paul
