Apple does not care about mpeg2. H264 is the decoder of choice across
all their platforms. The AppleTV can not do either 1080i nor 1080p
without hardware decoder assist.
Since 1080i content tends to be mpeg2 and 1080p tends to be
mpeg4/h264, you will never see an Apple supplied 1080i (mpeg2)
hardware assisted decoder on any of their platforms. 1080p is
possible but not likely.
You have to think where does the 1080p content come from. Right now,
1080p is ripped HD-DVD or Blue-ray and some BBC HDTV feeds. Apple
can easily stream 720p (that's their movie rental stuff) but who
streams 1080p -- no one. So no Apple supplied 1080p hardware assist
decoders for the AppleTV.
It's not a problem of the power of the hardware, with GPU hardware
assist, the AppleTV could do 1080p full bit stream decode. Apple does
not see a market for this so it will not happen under the native
AppleTV OS. There might be cpu bumps in the future but don't plan on
seeing a 2GHz Core2 Due inside. Wrong component price point.
Even under linux, 1080p is a software decode solution which means
plenty of cpu. There are no 1080p hardware assisted decoders for
mpeg4/H264 under Linux at the current time. Maybe under the new Intel
video driver push. Best bet is a +2GHz MacMini for a similar
