Picture in picture is faster than TV screen? Answered

I was just watching the Blackhawks win the Stanley Cup (woo), and my dad turned on picture in picture so we could see what another channel was broadcasting, but as a default it started on the same channel. The weird thing was the picture in picture was a full 1-2 seconds ahead (the audio was synched correctly with the main picture). It's an HDTV connected to a cable box.

This is pretty much the least important question ever, but I found it weird and wondered if anyone had any ideas.

The large picture may be going through additional image processing to sharpen it and otherwise adjust for the characteristics of your screen. The PIP is a least-effort rendering and wouldn't go through those stages. At least, that's how I would have designed it.

An that's probably right. I never noticed it on my set on analog tv but mine does the same thing on digi tv. There is a lot more processing going on in digi tv.
