SMPTE RP 179:2002

Abtract:

This practice specifies a method of coding film position, film frame to video frame phase relationship, transfer sync points, and production related data into binary groups of SMPTE time and control code. — The dialect specified defines the structure of directory page-lines 0A
h
to 0F
h
(page 0, lines 10 through 15), 1A
h
to 1F
h
(page 1, lines 10 through 15), 2F
h
(page 2, line 15), and D0
h
to EF
h
(pages 13 and 14, lines 0 through 15). This conforms to the multiplexing structure specified in ANSI/SMPTE 262M. — The page-line directory index, located in binary groups 8 and 7 of each time code frame, fully specifies the type of data stored in the remaining binary groups of that frame. — The encoding method is suitable to both linear time code (LTC) and to vertical interval time code (VITC).
