1080P HD signal is for when?
by Theguywhowannaknow - 5/23/07 1:50 PMAnyone know? In Canada, the current broadcast signals in HD is 1080i or 720P and i am pretty sure it is the same in USA (can anyone confirm?) but WHEN do you think we will see broadcasters sending a 1080P HD signal? 2008? 2009? Before?
When?
by ht_fan - 5/23/07 2:08 PM In reply to: 1080P HD signal is for when? by TheguywhowannaknowI don't think we will ever have 1080p transmission within the next 3 years, after that who knows what. I think it has to do with the setup cost for 1080p.
Andy, also in Canada.
(NT) more like 10-15 years away

by Dan Filice - 5/23/07 3:32 PM In reply to: (NT) more like 10-15 years away by givemeanameOne reason there is so much hype over 1080p is because of the gaming systems and HD/BluRay DVD players that output 1080p. I'm sure there will be more 1080p devices, but who knows when. So, let's look at this: If you have a 1080p TV and you use a native 1080p device, the signal stays 1080p. If you watch HDTV broadcast, then your 1080p TV will scale the 720p/1080i signal up to the native 1080p. So, many people worry that if they have a 720p/1080i TV, their TV will show a degraded image when using a 1080p device because the 1080p signal is scaled down. Well, any scaling in theory, will alter the image some, so why aren't more people worried that using a 1080p native TV to watch HD broadcast will degrade the picture too? The argument should work both ways but it doesn't.
sorry,stupid question but..
by Theguywhowannaknow - 5/23/07 3:49 PM In reply to: The hype over 1080p by Dan Filicewhat do you mean by "using a native 1080P device"??? Do you talk about the A/C? I know digital receivers from Dish Network or cable compagnies are all 1080i for the HD signals so you arent talking about those devices right? Do you mean the A/C or dvd player from wich the TV is plug? sorry but i'm dumb i guess... 
Im still waiting for more HD channels
by misterguy - 5/24/07 4:30 AM In reply to: sorry,stupid question but.. by TheguywhowannaknowDan you brought up an interesting subject. The argument really should work both ways. When 1080p was first coming out I thought that it was a complete waste of money. Especially because many people were online saying that hd 1080i dvd players looked just as good or better than bluray 1080p players. Add to that, your tv would now have to upscale 1080i from your cable box. Then I started really looking at the new tvs and its obvious how nice and sharp their picture is. Theguywhowannaknow, I think Dan means a device that will output 1080p to your tv. Like a 1080p HD DVD player or gaming system.
Bad Info!
by greasedog - 6/13/09 5:45 PM In reply to: The hype over 1080p by Dan FiliceIt is not true that a 1080p tv will automatically upscale any hd signal broadcast in less than 1080p to 1080p. A 1080p capable tv can only display the signal sent to it. A 480i signal sent to a 1080p tv will display in 480i resolution. A 1080i signal sent to a 1080p tv will display in 1080i. A 720p signal(currently the highest broadcast resolution available) sent to a 1080p tv will only display in 720p resolution. I own a 1080p mitsubishi big screen tv and hd dvr. The only true 1080p resolution it can display is from my blu-ray player and some internet sources. 1080p tv can only display 1080p from 1080p signal source. Currently, there are no 1080p broadcast sources.
There are 1080p broadcasts today.
by kcfvegas - 6/20/09 11:58 PM In reply to: When? by ht_fanWhile for the most part the different posters are correct, that broadcasts today are in 1080i or 720p, DirecTV does have 1080p, and I think Dish also has 1080p on certain pay per view movie channels. As for the regular channels, I agree that 1080p is a ways off.
In the US there will not be any 1080p broadcast!!!!!!
by jcrobso - 5/24/07 2:26 PM In reply to: 1080P HD signal is for when? by TheguywhowannaknowThe bandwidth of OTA Broadcasts is 18mega bits/sec per channel!!!!!!!
720p and 1080i have around 50mega bits/sec bandwidths and must be compressed to fit into the 18mega bit/sec broadcast bandwidth.
1080p has a bandwidth of 125mega bits/sec, It would have to compressed so much that it would look worse than ED video after uncompression.
1080p is the realm of HD-DVD/B-ray. John
Wow! That was new to me!!!
by Theguywhowannaknow - 5/24/07 7:24 PM In reply to: In the US there will not be any 1080p broadcast!!!!!! by jcrobsoDont you think there will be a new technology by then? Anyway, as you wrote, 1080P is a fit for HD dvd or Blue Ray but i still hope we will ever see a 1080P HD signal in a near future...
WHY ARE YOU STRESSING ABOUT 1080p
by stewart norrie - 5/25/07 3:53 PM In reply to: Wow! That was new to me!!! by Theguywhowannaknowwith a good system 1080I will give you an eyepopping picture as good aor better than any movie theater in yown. what are you looking for something that is better than perfect Yes my 1080P blue ray player looks mabey 2% better than 1080I from my hi-def satellite system The only one that may use deep color, 1080P and 1.3. would be someone building a million dollor home theater system. these folks can afford the money to have 2% better picture and sound stewee
Eventually there WILL
by froasier - 5/26/07 1:59 PM In reply to: In the US there will not be any 1080p broadcast!!!!!! by jcrobso...be a new broadcasting standard with enough bandwidth for a compressed 1080p signal. It confuses me why it takes more bandwidth though! 1080i is 60 fields per second, so deinterlaced it is 1080p at 24 or 30 frames per second--half the lines... twice the refresh rate... should equal same bandwidth! It would be one thing if we were talking about 1080p at 60fps but we're not--even HD-DVD and BD are only 24fps. Eventually 1080p60 will be the standard for everything, but right now I don't see why 1080p is so hard to accomplish at 24 or 30 fps. Does anyone have this figured out?
Reread my post about bandwidth!!!!!
by jcrobso - 5/27/07 5:43 PM In reply to: Eventually there WILL by froasierThere is a war going on!!!! The war is over broadcast bandwidth!!!!!
Keep in mind that it took 20 years to get the 720p and 1080i HDTV broadcasts that we have now. Don't hold your breath waiting for 1080p!!!
Sadly MPG2 was chosen for OTA broadcasts. DirectTV and Dish have started changing over to MP4 encoding to give them more bandwidth, all of the receiver must be replaced. Not to give you better quality but for more channels!
There ARE broadcast standards!!!! The standards dictate how video will be transmitted! In the US it's NTSC for analog video and ATSC for Digital, the FCC has only given broadcasters 18mega bits/sec!!!! John
umm... i already read your post
by froasier - 5/27/07 6:28 PM In reply to: Reread my post about bandwidth!!!!! by jcrobsoI know there are standards--that's why I said "NEW" standards; eventually they will change it to more than 18mbps and/or switch to a better compression technology such as mp4. I'm obviously not holding my breath because I said "EVENTUALLY." Please limit your responses to helpful and relevant information.
1080p
by Funster - 5/26/07 1:18 PM In reply to: 1080P HD signal is for when? by Theguywhowannaknow1080p (24fps to match up with film) already is an ATSC standard. It could be broadcast right now if they wanted to. Would it result in a better picture? No, not if the interlacing and deinterlacing are done properly.
