DM368 VPFE 16 bit YCbCr color coding - BT601 or BT709?

TMS320DM36x Digital Media System-on-Chip (DMSoC) Video Processing Front End (VPFE) document
says DM368 is copmplient to standards: ITU-R BT.601/656/1120

BT601 conversion is used for standard definition,
Y ′ = 0.299 R ′ + 0.587 G ′ + 0.114 B'
Cr=(-0.299 R' -0.587 G' +0.886 B')/1.772
Cr =  (0.701 R'- 0.587 G'- 0.114 B')/1.402

BT709 for High Definition.
Y′ = 0.2126 R′ + 0.7152 G′ + 0.0722 B′
Cb =  (−0.2126 R′ −0.7152 G′ +0.9278 B′)/1.8556
Cr= (0.7874 R′ − 0.7152 G′ − 0.0722 B)/1.5748

BT1120 standard refers BT709 for color coding, BT656 refers BT601 accordingly.

I believe BT709 color coding is used for BT1120 video capture.

I use generuc YCbCr 16 bit input of HD video. What color coding is convention is used by DM368 for my case - BT601 or BT709?

My video: Input 1980x1080 30p, resized to 1280x720 with VPFE resizer, H264, RTP

I've got impression BT601 is used instead of BT709.

Thanks,
