Linux: Capture+Display through HDCOMP out in DM388

Hi Brijesh,

Thanks for your reply.

We are using ADV723 encoder which is connected to HDCOMP in DM388.

Is there any other way to test with HDDAC ?

Thanks for the response.

Is S-Video(NTSC\PAL) output supported using HDDAC in IPNC RDK 3.9.1 ?

I believe on DM388 S-Video is not supported on SDDAC, is that correct?

We need S-Video Out to support NTSC\PAL so we are connecting HDDAC output to NTSC\PAL encoder-ADV723 on our custom board.

Is it possible to support 480i and/or 576i RGB format output through HD-DAC?

Hi Brijesh,

Is 480i and 576i RGB output possible through HDCOMP? i am using IPNC RDK 3.9.1.

Hi Narsimha,

It should be, don't know or don't remember if it is tested. Please try it out.

Rgds,

Hi Brijesh,

I tried 480i output on HDCOMP but i get 480p output on display

I see following check in Display link. Only for 1080i, NTSC, PAL scan format is set to interlaced. Maybe that's why i get progressive output even when i selected 480i in display link.

Do you have any suggestions on what i should try to get 480i output??
