Abstract:
The present invention provides an apparatus for generating a time code compatible with 50P, 60P or 59.94P and having interchangeability with existing time codes. The apparatus includes: a microcomputer for dividing a frame number indicated by time address data in supplied code word data to obtain a quotient and a remainder; and the microcomputer and a time code reader for replacing the frame number indicated by the time address data in the code word data with the quotient and for generating a time code based on the code word data in which a value of a color frame flag is set to 0 if the remainder is 0 and for replacing the frame number with the quotient and for generating the time code based on the code word data in which the value of the color frame flag is set to 1 if the remainder is 1.
