I have a Sharp Aquos 46D62U TV and a VIP 722 receiver. When I try to download a 1080P VOD I get the message - Incompatable video signal - What specifications does the set have to meet to download and display a VOD 1080P
1080P

My Sharp Aquos does not do 24fps, just 60fps - so I'm outta luck. Sorry Bobmiller - no fix yet. I keep trying though. You can go to MENU - 6 - 3 - and then check the HDMI settings (a couple pages down) and see what your compatible modes are). Note that 1080p 24fps is not listed (most likely if you have a Sharp Aquos).
Wont be any fix on this line of DVR"s. The current broadcom chip can only 1080p/24. I think they new chip they are working on will do 1080p/60.
That would be awesome. I wish I had known that about the Sharp Aquos prior to purchase. Everything else I like about it, except that I didn't know about the standard/native 24fps. There is so much hype about the other rates and bigger is usually better.
I might be better off finding another TV - that thing looks like it's going to be expensive. The 1080i picture sure looks great on my HDTV though - so I'm happy. I'm sure we'll hear all about the 922 chip regarding the 1080p - since it's such a common topic here.
Really no difference between 1080i/60 and 1080p/24, its just that many tv's dont handle 1080i/60 correctly. 1080p/24 file size is smaller too, prob why the providers like it.
As you probably know, the BCM7400 in the 722k/922 does not support 1080p60.
Broadcom announced its first DVR SoCs with full 1080p60 support back in January, but you won't see them in any Dish Network or DirecTV DVRs until 2010. Those solutions are just vaporware at this point.
The optimal format for viewing motion pictures on a digital video display is 1080P24.
1080p60 requires much more processing and more than double the data rate.
1080p60 is not practical for any type of broadcast transmission, either OTA or satellite and for motion pictures it is counter productive (the mp must be recoded from the original 1080p24 up to 1080p60 then the TV has to pull it back down to display it smoothly.
Most movies on Blu-Ray are 1080p24.

No one is talking about sending 1080p60. Not even Broadcom.
Broadcom advocates the feature as a way to output 1080p24 content at 1080p60. They support the deinterlace of 1080i into 1080p, which they claim is better than you get in some older 1080p TVs. The BCM7410 and BCM7420 will support a "fixed 1080p60" output setting.
The quality of Broadcom's 1080p deinterlace implementation remains to be seen, but at least in theory, doing it within the decoder SoC should eliminate the need to do more computationally intensive cadence detection. The SoC has access to all the original decoder hints, so it knows which programs are actually 1080p24 sources sent within a 1080i60 signal.
