The US-spec Avant has one component video input (presumably) for a set top box. There is a menu option for "generic" that allows the AppleTV to work perfectly. Again the limiting factor is the Remote Control issue.

BTW, AppleTV is great for audio (within the limits of compressed digital music). However, the Avant's excellent image shows the poor quality of video available from Itunes.

I've thought about BeoMedia, but it is quite expensive compared to AppleTV ($299 in the U.S.). I also wonder how much it would cost to upgrade the Avant to control BeoMedia if it is at all possible here in the U.S.). While I've not yet seen BeoMedia, I admit it is probably the "best" solution for B&O.
 

Certainly it does video. My point is that with a B&O TV you can see all the flaws in a less than great video source. Perhaps though as pointed out above, new codecs will mean HD video content. The current video quality from AppleTV falls somewhere b/t VHS and DVD. I think we all agree that it's hard to beat the image of a well mastered DVD on an Avant screen. I've yet to see the flat screens in any fashion other than just casual admiration, but until I get the $19,000 to upgrade, I'll continue to enjoy my Avant.

Similar criticisms can be made of compressed audio as well, though for my purposes mp3 files encoded at between 192 and 320 are good enough. For "serious" listening especially of classical music, I think CDs are still the way.
 

On the US Avant you can also use a Zektor HDS4 which is a component video switcher that the BeoSystem 1 has the ability to control.  You can select High Def sources for other inputs (ie. Toshiba HD-A1 in DVD, High Def STB in STB, Apple TV in V.Aux maybe?) and BeoSystem 1 will control which input the Zektor box will select as well as the component itself.  Of course, you plug all the other connections into the input you are trying to control.

It's a pretty sweet way of using multiple component sources with BeoSystem 1, which is limited to just one.

If Apple TV gets added to the Avant/BeoSystem 1/2 STB-C/CCDB then thats probably how it will have to work.

OK, complete control of AppleTV with Beo4 and Lintronic. No true fast scrolling. Still waiting on that! Not completely intuitive, but all functions work perfectly. For fast scrolling I simply programmed the up and down commands to repeat 10 times. That's about one page at a time.

Next is Beo1 + Lintronic for AppleTV control. I know it'll work, just ran out of time.
