For that I apologize. And my fault.
But as it's something that is out on the internet for folk to catch up on I can't detail each technology item unless the discussion is about that lone item. Here we need to cover a few topics at a fairly high level and if I wrote what MacroVision was then next thing I know is someone tells me I got it wrong. Then I copy/link some other site/text and then folk slam me for plagiarism.
Ouch. I think I'll forever be apologizing.
