About Laserdiscs, part 3 (errata)

After the last post, I realized that I inadvertantly placed the white flag on line 12, when it is actually on line 11. This caused quite a bit of difficulty as I was trying to get the VBI example picture to line up and it wasn't quite working.

Anyway, I have corrected the article to fix this oversight and provide a brand new VBI example. For this one I have correct line numbers and also overlaid the Philips code binary value on top of the VBI data so it is clearer how it gets extracted.
