What resolution is your TV?
![Hdmi]()
480i, 480p, 720p, 1080i and 1080p, what does this mean?
Standard TV since the days of black and white to color images that we see today on television every day are composed of a series of still images at 60 frames per second in the U.S. and has presented 50 frames per second in Europe. These still images consist of individual lines of information from left to right on the screen of several lines down moves forward. With a cathode ray tube (CRT) televisions that most of the old "Used for display, the flat surface that you see on the inside with phosphor dots or rectangles covered. A beam of electrons on the dots or rectangles what they want to shine. Available with a standard definition TV that 480 of these lines and 640 series of dots or rectangles on each line. Each set of points or rectangles made up of three color dots (red, blue and green) and determines the strength or intensity of an electron, as any bright color. Actually there are three raysMovement along the face on the screen, any change in intensity as to cross the phosphor dots or rectangles.
Interlaced (i) or progressive (p)?
To reduce the bandwidth normally sends TV signals only 30/25 frames per second for the recipient, only 240 lines of information. If this were all that was seen on the screen flashes like the old movies. Processed in the television signal, and twice sent to the CRT, the odd lines are scannedand then the even lines are scanned with the same image. This is called an interlaced image and eliminates the flicker. But the real vertical resolution is only 240
With a progressive image is 60/50 frames per second for the receiver and all lines are scanned once for each image and offers twice as detailed as the interlaced image posted with the screen itself. However, this requires twice the bandwidth. Note that digital terrestrial has only 240 linesthe original information, you can use a line doubler or scaler to increase the number of lines, but it is not as sharp as the original image.
Horizontal resolution is much easier it is basically just the number of dots, rectangles or pixels in screen width. For example, standard definition TV is 640 x 480, the horizontal resolution is 640 for both interlaced and progressive.
Standard definition DVDs in full screen and widescreen
With the introduction ofDVD 'The horizontal resolution of 640-720, increases show larger images of the original film. Display with a resolution of "720 X 480" might show these movies with the full width of the screen, but when you watch standard television images, people are a little 'thicker.
Greater definition TV
This format uses progressive scanning and a wider framework of "854 x 480" and, although much better than standard TV is still not nearly high-definition TV. TV Standardsusually have a black bar on each page, what people would be strange, so fat.
HDTV 720p
This format was a big step forward, but when you watch normal TV, is still back in the old format "640 X 480" fixed. View 720P has a resolution of "1280 720" and use progressive scan picture very sharp. Scalers and converters are used to increase the quality of television images to fit the screen. For analog signals, component video cable and a deviceMinimum requirement. Video and S-video does not work. The TV can accept video and S-video, but not the benefits of full resolution shows a smaller image or processing in the TV provide a bigger picture, although not as sharp.
The government has started with 720p and 1080i high definition TV standard
On February 17, 2009, the television station to stop all analog broadcasts and digital broadcasts only. Old analog TVs will need converter boxes to receiveprogramming on the air. Cable or satellite service will not be affected. There are two formats that are used by different stations.
The 720p format makes a picture with 720 lines with 1280 pixels horizontally or with a resolution of "1280 x 720". 720p uses progressive scanning, like computers, which sends a complete picture 60 times per second. 720p provides the smoothest possible motion reproduction, but lacks the resolution up to 1080i.
The 1080thSize makes a 1080 vertical lines, each with 1920 pixels horizontally or with a resolution of "1920 x 1080". 1080th uses interlaced scanning, like traditional TV, which in turn sending odd and even lines and lines it sends a complete picture 30 times per second. 1080th offers the highest resolution possible, but has made the same motion as a traditional TV.
1080p High Definition DVD
The next DVD will probably be able to 50GB of DVD is that the use of the gamea High Definition Multimedia Interface (HDMI), which will also provide up to 7 channels of high definition with the 1080p image. This is rapidly becoming the standard for DVD movies in the same way that DVD replaced video cassettes in a few years ago.
To view videos you need an HDTV with HDMI input and a DVD player, the new format with an HDMI output. In addition, you need to connect HDMI cables to the special two. Your cable or satellite provider will alsoUsing HDMI connections, so you need at least two HDMI ports on your screen.
There are some disadvantages of current models of high-definition DVD player. High-bandwidth Digital Content Protection (HDCP), creates a slowdown at the beginning of a movie, you might think that you have a problem with your DVD. The player is only talking to the display device to ensure that they are both licensed. Unless you are on the DVD are on a screen 42 inches or larger, has adifficult to tell the difference between 720p and 1080p.
Banda large what does it mean?
Now you can have broadband and do not even notice. How many times have a movie online from your local cable or dish company? Have you noticed how many high-definition capabilities are offered? Since the selection is greater, is currently streaming has become so common that we forget to slow our DVD players. 1080p, 720p is very common and will soon be available.The protection for the film producer is already there, such as high-definition boxes use HDMI with HDCP for high-definition outputs.
Organic Light Emitting Diode (OLED) TV
Then comes the OLED, we are with them already on the new mobile phones and laptops. The first OLED television was introduced in 2008. With increasing demand for larger displays and the pipeline, which is now full of plasma and LCD screen has started to empty, you hear more and more the quality of the color ofOLED. For several years, the resolution of the display will remain the same and the sales pitch of the colors. But keep in mind that there is no limit to the size of the screen, with OLED and is also flexible. That is flexible to allow for easer handling and installation.
Since the screen size increases the demand for higher resolution is to start from scratch. And flexibility is the possibility of 360 degrees all around-a-screens. Remember that theHorizontal resolution is much easier than to get a similar vertical resolution of 16000 (or higher) X 1080p is not in question. Not at 360 degrees movies are new, had a Disney World in Orlando in operation for years. You're standing in the middle of a large group and turn around to follow the action. A few chairs and spinning, the screen rises a few feet away you go.
