To me, HDMI means a flimsy and fragile non-locking multi-contact connector on the end of a cable with the flexibility of frozen garden hose plugged into another flimsy and fragile non-locking multi-contact connector which can be snapped off the PC board it's glued to with a quick flick of the wrist. And then there's the issue of trying to get meaningful performance measurements by testing cables on your own. To do that now, need to invest over $30K in test gear...just to see how badly the cable might corrupt the signal. Well conceived, well engineered, well done indeed. And yes, it WAS all about HDCP, or the other existing one-cable solutions would have been fine.
Kudos to CEDIA for coming up with a trouble-shooting guide that should never have been necessary in the first place.
What we needed (and still need) is a single-cable interconnect solution that uses robust locking (field installable!!!!) connectors on flexible cable and just plain works all the time, with reasonable and useful length limits. It could even be anti-copy savvy. In fact, the one over-riding requirement is that the new cable solution actually be engineered instead of created by a committee sticking post-it notes to a white board.
"Oh, but now we need to add 3D"
"Oh, but what about hi-def audio"
"Oh, we almost forgot deep color!"
"Oh, we need to add control hand-shaking"
Oh, give me a break!
