    I am looking at Item 5.6 of the BT.709 spec:

    https://www.itu.int/dms_pubrec/itu-r/rec/bt/R-REC-BT.709-6-201506-I!!PDF-E.pdf

    It says there are 2,200 samples per full line (for "NTSC" frame rates).

    Can I infer that in a 1920 x 1080 raster, there are 2200 - 1920 = 280 samples of "horizontal blanking" per scan line?

    Yes, remember this is only for displays such as analog or DVI.
