Talk:SMPTE timecode

From the article:

Some of the bits also tell whether the timing is for 24 frames/sec (film), 25 frames/sec (European video), 30 frames/sec (black & white NTSC (archaic)), or 29.97 frames/sec (30/sec drop-frame color NTSC).

Wrong. There are colour frame and drop-frame bits, but they don't tell you the basic frame rate. Indeed, the drop-frame bit is not necessarily meaningful in a 25 fps timecode. However, you can always tell the underlying frame rate, as you are either using an LTC decoder (in which case you can get the rate from the underlying bit-rate, or from watching the rate of arrival of decoded frames, or decode it from watching the frame count rollover) or are using a VITC decoder (in which case you either already know the rate, or can read it from the hardware, or infer it from the rate of arrival of code frames, or decode it from watching the frame count rollover)
