As a rule, the association does not develop standards itself, but acts as a forum and documentation authority. Almost all manufacturers in the field of video technology are members of this association. Therefore, the agreements documented by the SMPTE form the basis in this technology area alongside the ITU and ANSI standards.

The most important standards on which the SMPTE has played a decisive role in the past:

  • Standards for video and film cassettes, 1964 to date
  • Standardization of the timecode: SMPTE timecode , 1967/1969
  • Standardization of HDTV , 1981 to date
