Other Parts Discussed in Thread: TMS320C6748

Dear expert.

 

I'm going to use Rec.1120 video receive interface on C6748 VPIF.

Should I use 1080p 30fps camera input for Rec.1120 ?

Because I want to use Mobile Camera that output 15 fps so I'm worried about It is no problem to use.

Please let me know.

 

Best Regards.

Jay.

    Jay,

    The Video Port Interface (VPIF) allows the capture and display of digital video streams.

    Up to 2 Video Capture Channels (Channel 0 and Channel 1)

    •         Two 8-bit Standard-Definition (SD) Video with embedded timing codes (BT.656)
    •         Single 16-bit High-Definition (HD) Video with embedded timing codes (BT.1120)
    •         Single Raw Video (8-/10-/12-bit)

    Up to 2 Video Display Channels (Channel 2 and Channel 3)

    •       Two 8-bit SD Video Display with embedded timing codes (BT.656)
    •       Single 16-bit HD Video Display with embedded timing codes (BT.1120)

     Refer the section "Table 34-1. Supported Formats on VPIF" in TMS320C6748 TRM (spruh79)
     TMS320C6748 VPIF supports both the 1080-30p and Rec.1120

    Dear Pubesh.

    Thank you for the answer.

    Yes, it support 1080p 30fps and Rec.1120.

    But what I want to know is Rec.1120 spec request 1080p 30fps input certainly.

    I want to give a camera input with 1080p 15fps and I'm worndering it is possible.

    Best Regards.

    Jay.

    Hi,

    Yes you can do that. Suppose you VPIF driver is capable of say capturing @15fps rate.

    Alternatively if you are able to capture 1080P30fps you can drop alternative frames in the

    capture driver and capture @1080P15fps.

    Jay,

    Rec.1120 supports 1080-30p, however you can configure for 1080-15fps. In this case your video quailty will be affect. If you want full HD motion, go for 30fps.

     Refer the Rec.1120 document for detailed information.
