BT1120 of DM368 is 10bit or 16bit?

ruqun xu

I want to use BT1120 interface of DM368.

In the datasheet of DM368 ,it says the BT1120 is 16bit.

For BT.1120, Data width is 16bits and the registers would be configured as:
MODESET.INPMOD = 1 .... YCbCr16bit
REC656IF.R656ON = 1 .... ITU-R BT.656 interface mode set
CCDCFG.BW656 = 0 .... SYNC detection on C7-C0

But I find the format of BT1120 is 10bit/12bit.

It is different from the datasheet of DM368.

I do not know why.And what can I do for the format.

Thanks.

Hi,

Which spec did you check for BT1120? What I found in BT1120 spec is that the video data is 8-bit or 10-bit words. So there is no problem for DM368 to receive the BT1120 format data.

The datasheet is "TMS320DM36x DMSoC Video Processing Front End User's Guide (Rev. C).pdf".

Page 47.

It says these following setences:

But I know the BT1120 is not 16 bit.

Hi,

Why do you say BT1120 is not 16 bit? Pls kindly do some search in google .

The spec I mentioned in previous post refers to BT1120 spec.

Sorry.

I download the file "ITU-R BT.1120-4" and " BT.1120-7".

But I find the data is 10 bit not 16 bit.

Maybe I download the wrong file.

Can you recommend some file?

Thanks for your help.
