Does cox cable use 1080p?
Negative, no networks broadcast in 1080P yet, it does 720P and 1080i
Will a 1080p work with a 720p and 1080i broadcast?
Yes, if you use the proper cables
What kind of formats are available for HDTV televisions?
There are three types of HD formats-720p, 1080i, and 1080p. Progressive and Interlaced Scanning are also available for an HDTV to use.
Do 1080p TV sets convert 1080i signal to 1080p format?
All LCD displays use progressive scanning, namely the whole frame is built up line by line rather than odd lines followed by even lines. Therefore, by default, 1080i will be converted to 1080p, but at a frame rate of 25Hz or 29.97Hz. 1080p sets take 1080i cable or satellite signal and convert (deinterlace) it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass, and this process (in the US) happens 60 times per second. 1080p is normally run at 50Hz (Europe) or 59.94Hz (North America). 1080i is normally half that frequency. Even if the signal is converted from 1080i to 1080p, there is no additional picture information and therefore, little is gained by the conversion. If the television actually does the conversion, it is worth doing a comparison between converted and unconverted to see which produces the most pleasing results.
Why won't a 1080P TV receive a 1080P signal?
Broadcast television currently does not use 1080p. The HD formats in use at present are 720p and 1080i. The "i" stands for interlaced and it means that on a single pass of the screen half of the image is built up. The second pass sees the remainder of the image added to the first half. A full image is delivered 25 or 30 times each second. A 1080p signal delivers a full image on every pass, 50 or 60 times each second. 1080p therefore needs double the amount of data compared to 1080i. Broadcast infrastructure and the extra bandwidth requirements prevent 1080p being broadcast. 1080p is limited at present to Bluray and other local HD sources such as computers and game consoles. Don't expect to see 1080p from your television service provider any time soon. The 1080p identification on the television says that it will display 1080p but of course can only do this with a 1080p incoming signal.
What are the currently available sources of 1080p TV signal?
1080p is not currently being used in live television production and is not being broadcast at present. Broadcasters are still migrating to 1080i and 720p formats and the majority of HD production equipment will not support 1080p. No doubt, it will come in time but expect broadcast 1080p to be some years away yet. The Sony PS3 boasts the ability to deliver 1080p as do certain other local devices. Personally, I am not aware of any 1080p material that is commonly available, even on disc. More will become available in the future but the push towards 1080i needs to be largely completed before broadcasters and film distributors look seriously at 1080p as the preferred format. It would be useful for anyone with additional 1080p devices for demostic use to list some here.
What is the difference between hdtv and 1080p hdtv?
HDTV is the term for a range of television formats. The common formats in use today are 720p, 1080i and 1080p. There are other resolutions that can also be classed as HD but are not in use today. Each of the resolutions can be delivered at a variety of frame rates. 1080p is just one format in the HDTV class. It uses 1920 x 1080 pixels and the image is created by a single pass of the screen from the top to the bottom of the image. Contrast this with 1080i which requires two passes of the screen from top to bottom to create a full and complete image. 720p and 1080i are the two formats used for broadcast at present. 1080p is found in local sources such as games consoles and Bluray discs but not yet in live broadcasts. Any HDTV will handle any of the HD formats without any user set up required.
What is a HDMI port for xbox 360?
HDMI stands for High-Definition Multimedia Interface which is a cable you can use to play game in HD 720p,1080p and 1080i on a HD full TV or HD ready
How do you change a Panasonic tc-p50s1 from 720p to 1080p?
The process is very simple - you don't.HD television can be broadcast in one of two formats. 720p is one and 1080i is the other. Local sources such as Bluray and games consoles can also use 1080p. All HD televisions will accept any of the formats and display them without any adjustment by the user. Therefore, users will not be aware of the specific format used in most cases.There are some exceptions: Some older HD televisions cannot handle 1080p signals. While this is rare in current televisions, if 1080p signals cannot be shown, check in the manual to see if they can be accepted. If not, the source will need to be adjusted to operate at 1080i rather than 1080p.
Dynex 46 LCD 1080p running at 720p change back to 1080p?
HD televisions are capable to displaying several HD formats. The most common are 1080i, 1080p and 720p. All HD signals will be in one of those three formats and the television will automatically accept and display any of the formats. The on screen report that the display is running at 720p is simply an indication that the incoming signal is in that format. Change the incoming signal to 1080 and the status will change to show 1080. Note that 1080i and 720p are both true HD formats and broadcasters are free to use either format. 720p is less used but it may be found on sports channels as it handles high speed movement a little better than 1080i.
What does 1080p stands for?
1080p is a high definition video format. 1080 refers to the number of lines that make up the complete image. The "p" stands for "progressive". A progressive format builds the complete image from line 1 to line 1080. 1080i has the same number of lines but is an interlaced format. The picture is built in two passes. The first pass has all the odd numbered lines - 1, 3, 5, 7 and so on to line1079. The next pass has the even numbered lines - 2, 4, 6 through to line 1080. Information is delivered twice as fast with 1080p compared to 1080i. Currently, broadcasters do not use 1080p which is found only on local sources such as Bluray, games consoles and computers.
What is the difference in 1080p and 720p technology in HD tv?
High definition television uses one of three common formats - 720p, 1080i and 1080p.720p indicates that there are 720 lines in the image. The "p" means "progressive" and a complete image is delivered 50 or 60 times each second.1080i shows that there are 1080 lines. The "i" stands for "interlaced" and the image is sent in two halves so a half image is sent 50 or 60 times each second but the full frame is sent only 25 or 30 times each second.1080p is also made up with 1080 lines but the "p" shows that a full image is delivered 50 or 60 times each second.Broadcasters use 720p or 1080i. These are both full HD signals. Although the 720 line image has a lower resolution, it is updated twice as fast. The data rate for 720p and 1080i is the same. Although 720p is less common than 1080i, it is used by broadcasters for some fast action content such as sports.1080p updates the image at twice the rate of 1080 and therefore uses double the bandwidth. Broadcasters do not send out 1080p and it is restricted to local sources such as Bluray, games consoles etc.
