While the ATSC standard does allow 1080P with frame rates of 23.976 to 30 fps no one is using it due to high bandwidth requirements..

1080p at 24-30fps has not much more bandwidth requirements to 1080i50/60, infact it could be stated it has less. Its 1080p50/60 that has a heavy foot.

Also, USA is the only country to broadcast 1080p. If Europe can't acheive this, we won't ever get it, still, 1080i is massively superior to anything we've ever seen & I'm very happy with the status quo.


Who in the USA is transmitting 1080p?

My recollection was this was the case a couple of years back when I was researching on avsforum.com. Apparently, now the broadcasters have cut back, to what is generally known over there as HD lite, due to the bandwidth constraints with the more channels they are running.

Here is a thread on the issue. http://www.avsforum.com/avs-vb/showthread.php?t=1018525&highlight=1080p

yep definite macroblocking and other technical masties in that AVS thread, if you look carefully at those Miss USA pics its very plain to see.

Depends where you watching it. One Sky here in NZ yes but on FTA  you should not as we are getting a sat feed from the US which may have macroblocking  due to the satelite provider..   or a prerecoded show that should have no macroblocking at all..

It's DirectTV and possibly the other provider trying to meet their claims of 100HD channels. With a limit on transponders and the need for local stations, they are stuffing as many channels down the satellite they can. This requires that the picture be compressed more and bandwidth reduced.

Certainly when I was there last, watching OTA HD (albeit over cable), the PQ was excellent. In the area I was, Comcast (despite what they are doing to Internet and bandwidth shaping), was sending down pretty much the uncompressed ATSC signal they pick up over the air.
