ST 12-3:2016 - SMPTE Standard - Time Code for High Frame Rate Signals and
Formatting in the Ancillary Data Space

Abstract:This standard specifies time code formats with the frame counts
72, 96, 100 and 120 and the frame count 120 with drop-frame compensation.
This standard also specifies a transmission format for conveyance of the
time code and frame count in the ancillary data space of serial digital
interfaces.

but try to get also all pdfs from

https://www.smpte.org/free-standards-and-publications

while you can..  downloading pdfs from tbis site seems to fail me probably
due to my location (may be i have them on my main machine, but my machine
is 1700km away and offline)
