Well, mmh. Doesn't the colour standard cleverly embed colour encoding digitally into the analogue B&W signal in such a way that it makes little/no difference to the visuals, but it can be separated out quite easily?
Seems to me that this is the ideal way to piggyback extra framing information. Embed it in the colour 'signal' somewhere, either time-based encoding of particular "colour values" and/or change the interpretation of the bits from the colour stream so that particular combinations can mean "new frame".
Just my 2c.
