ABSTRACT:
A standards converter converts an input video signal having time codes from a first television standard to a second television standard. The time codes are separated from the input video signal to obtain hours, minutes, and seconds values and input frame numbers. The hours, minutes, and seconds values are stored in a memory. Output frame numbers are generated in a consecutive sequence, from a first frame number to a last frame number, starting at times that are synchronized with the start of the sequence of input frame numbers. The output frame numbers are combined with the hours, minutes, and seconds values stored in the memory to generate output time codes, which are combined with the converted video signal.
