VBIT - USB Teletext inserter

From blogpics

VBIT, as the pocket inserter is now called is up and running as far as the hardware is concerned. A few fixes to the power and pullups and a signal line that had to be added and it is now producing vbi. What sort of vbi I have no idea as my ex-military scope doesn't do TV signals. But it means that the video path and the FIFO are all operating. Now I only have two things left to do.

1) Fit it into a case
2) Write the software.

This week I'm going to try generating packet 8/30/1 and maybe some Softel optouts as those are simple single packets. But the full text service could take a few months to implement assuming that the processor can work fast enough. And when summer comes I won't want to spend all the evening picking through code.
