Oh dear. This is really TOO funny.
OK kids, lets think this through.
The Very Big Corporation of Japan is making a new display with HDMI V1.3. They know their display can produce severe lip sync problems because of its fancy new, brand name video processing (for which customers pay a premium).
But not to worry! Just pair up the display with the new receiver VBC, Japan, are ALSO producing and the lip sync problem magically goes away!
Uh, unless the display is hooked up to somebody else's receiver that only has HDMI V1.1 output. Or Component output. Man, our display looks really bad compared to the competition when fed that way.
Gee whiz, do we really want to limit sales of our displays to just those people who will ALSO buy one of our fancy new receivers? I mean sure we want both sales but why give up sales to other companies for folks who are only buying a display?
So OK you guys in engineering (say the bosses sternly), fix this dang lip sync problem IN THE DISPLAY ITSELF!
But wait, says marketing, that eliminates one of the reasons for people to toss their old stuff too soon and buy our new stuff featuring HDMI V1.3!
Not to worry, say the bosses. Just tell them they need it ANYWAY even though the problem doesn't really exist. They won't know the difference.
