Check the article in Circuit Cellar INK issue 45 about the Vertical Blanking
Interval Explorer, one of their design contest winners.  The time code was
one of the things the explorer would decode, and there was a description of
the signal format.

The 8051 code for the project and a PostScript version of the original design
contest entry are available from their net server:
