Didn't realize they were so broad in scope. The only thing I had heard of was "SMPTE codes" used in audio recording to sync up multiple multi-track recording machines, so that e.g. you could record 30 tracks using two 16-track recorders (with one track on each machine used for the sync). I never bothered to look up what SMPTE meant.
You’re likely referring to SMPTE timecode, a method of conveying timing information about a video signal (eg. HH:MM:SS:FF), which is SMPTE 12M. There are various ways that timecode is conveyed in media such as LTC (linear timecode, usually carried as an audio signal), VITC (vertical interval timecode, in the vertical blanking interval of a video signal), and others.
