Anyway...I was wondering how cable was offering 3D TV when their bandwidth was tapped out with coax. Once I was informed that cable swapped out the coax with fiber...that explained everything. Most of cables actions to keep their customers from leaving makes sense.
Your using a rather BROAD brush when saying Cable offers 3D using fiber.
There are tons of Cable Co.'s that are NOT using fiber near the homes, some are but very few at this point.
Who says thier bandwidth is tapped out, again, a very broad brush, some are, some not.... Many of the Cable Co's have went to what they call "Switched Cable now ... this saves a ton of bandwidth for them as instead of sending ALL the channels to your home, they are now sending ONLY the channels you request.
Now I'm wondering who will be the first to goto 1080p broadcast. The 1080p vs 1080i broadcast is another funny story to me. It's all about dollars and cents.
As far as the 1080i /1080p thing, need more specifics, are you talking NETWORKS (ABC,CBS,NBC,FOX) types or the USA, TNT, A&E type channels, it would take major money for the networks to do this as they would need new equipment at EVERY local station in order to provide it to all thier affiliates. Could they do the Top cities and say the hell with the others, sure, that could be done, but the expenses are HUGE to go 1080p and this just scratches the surface.
