    In theory it may be possible, but the compression required for over IP (right now) would degrade the signal WAAAAY too much.



    Keep in mind that you standard HD channel takes up, IIRC, the equivalent bandwidth of three regular analog channels. Trying to get that much data thru IP with the same quality, not there yet.



    Sling Media is doing a decent job.

    Eh what? MS is putting money into IPTV as is AT&T...which is sinking a ton of money into FTTN deployment to support IPTV. They still claim 18M homes by end of the 2008 roll out.



    And U-verse is doing HD over IP today.

    Compression is a bit high but likely not THAT much worse than satellite. If Verizon steps up to the plate and moves FiOS TV to IPTV they can do much better because FTTP is much better than ATT/SBC's FTTN. FTTP is a lot more future proof but also a lot more investment.

    Ok. The telecoms can do that, fine. Regarding the 18M homes; If we know anything we know that companies never inflate their estimates. But until the final product is as good as or better quality than OTA or cable not many are going to migrate.

    Yep, wow it sure is. And the images are filled with more artifacts than the Smithsonian.

    Huh?!? Satellite delievers the closest to native resolution available today, short of Blu-Ray, HD-DVD or OTA. Satellite may be many things, but highly compressed ain't one of 'em. Sorry to burst your bubble.



    FiOS is the best and most reasonable tech to date for delivery of such content. Even it has a LONG way to go. Copper, eh not so much...

    I understand why many folks want Apple TV to be all-in-one companion for your TV, but that's not what it's for.



    I am sorry if your HDTV is old and lacks ATSC tuner, but all recent HDTV models have one built-in. If your's don't have it, there will be cheap tuners on the market soon. And the fact is, majority watch TV from providers like cable, satellite, and IPTV. Supporting all is not yet practical and ATSC tuner on Apple TV will serve minority.



    Before tackling areas like DVR, Apple needs to iron out Apple TV as a media extender: (1) aside from few podcasts and trailers, no legitimate HD contents, (2) no rental option which is what majority wants, (3) no official multi-channel audio support, (4) no subtitles, and (5) missing 1080p support.

    Hmmm...I was comparing Dish to Comcast side by side and Comcast was doing HD better but had fewer channels but did have OnDemand.



    Cancelled Comcast in favor of FiOS and Dish anyway because there was a couple must have international channels not on Comcast (or FiOS TV) for the wife and...well...I wanted fiber to the house.



    Here are some numbers from AVS as measured between cable, E* and D* (D* = DirectTV E* = Dish).
