Unfortunately, this patent is more about extracting money from consumers and less about usability/compatibility.
For example, Apple’s ‘requirement’ that anyone making a video out plug for your ipod [you know, the one you bought, that was advertised with video-out capabilities], has to buy and include a chip whose sole purpose is to tell the iPod that, yes, the consumer as paid an additional tax to Apple to actually enable the use of video out.
Now, there would be a huge uproar and class action suit if there was a separate line item for this tax on the consumer’s receipt, but because Apple has buried this extra fee for enabling video out into the manufacturing cost, people don’t know they are paying this extra tax.
