What is Your Tv Resolution?

480i, 480p, 720p, 1080i and 1080p what does it all mean?

Standard Tv from the days of black and white to the present color images we watch every day on television are made up of a series of still images displayed at 60 frames a second in the Us and 50 frames a second in Europe. These still images consist of personel lines of facts that move from left to right over the screen followed by more lines lively down the screen. With a Cathode Ray Tube (Crt) that most older Tvs' use for the display, the flat surface that you look at is coated on the inside with phosphor dots or rectangles. A beam of electrons is aimed at the dots or rectangles causing them to glow. With a accepted definition Tv there are 480 of these lines and 640 sets of dots or rectangles on each line. Each set of dots or rectangles consist of three color dots (Red Blue and Green) and the power or intensity of the electron beam determines how lively each color will be. There are surely three beams lively together over the face of the screen, each changing in intensity as they cross the phosphor dots or rectangles.

In order to reduce the bandwidth, normal Tv signals only send 30/25 frames a second to the receiver made up of only 240 lines of information. If that were all we saw on the screen it would look like the old flickering movies. Within the Tv set the signal is processed and sent twice to the Crt, the odd numbered lines are scanned and then the even numbered lines are scanned with the same image. This is referred to as an interlaced image and eliminates the flicker. However the true vertical resolution is only 240.

With a progressive image, 60/50 frames a second are sent to the receiver and all of the lines are scanned once for each frame and providing twice the detail as the interlaced image with the same screen. However this requires twice the bandwidth. Keep in mind that non-digital over the air is only 240 lines of primary information, you can use a line doubler or scaler to growth the amount of lines, but it will never be as sharp as the primary image.

Horizontal resolution is much simpler, it is basically just the amount of dots, rectangles or pixels over the width of your screen. For example accepted definition Tv is 640 X 480, the horizontal resolution is 640 for both interlaced and progressive.

Standard Definition Dvd Full Screen and Wide screen

With the introduction of Dvds' the horizontal resolution was increased from 640 to 720 to show the wider images of the primary movies. Displays with a resolution of "720 X 480 " could show these movies using the full screen width, However when viewing accepted Tv images, the population are slightly fatter.

Enhanced Definition Tv

This format uses progressive scan and an even wider image for "854 X 480" and though is much better than accepted Tv it still does not come close to High Definition Tv. accepted Tv normally have a black bar on each side as the population would look weird being so fat.

720p High Definition Tv

This format was a big step forward, However when viewing quarterly Tv, you were still stuck back in the old format of "640 X 480". 720P displays have a resolution of "1280 x 720" and use progressive scan for a very sharp image. Scalers and converters are used to boost the capability of the Tv images to match the screen. For Analog signals, Component video tool and cables are a minimum requirement. Video and S-Video will not work. The Tv set may accept Video and S-Video, but will not take benefit of the full resolution, displaying a smaller image or straight through processing in the Tv provide a larger image though not as sharp.

The Government steps in with 720p and 1080i high Definition Tv Standards

On February 17, 2009, television stations will stop all analog broadcasts and only broadcast digitally. Older analog Tvs will require converter boxes to receive over the air programming. Cable or satellite service will not be affected. There are two formats that will be used by the distinct stations.

The 720p format makes a picture with 720 vertical lines, each with 1280 pixels horizontally or a resolution of "1280 x 720". 720p uses progressive scanning, like computers, which sends a perfect picture 60 times per second. 720p provides the smoothest possible request for retrial rendition, but it does not have as much resolution as 1080i.

The 1080i format makes a picture with 1080 vertical lines, each with 1920 pixels horizontally or a resolution of "1920 x 1080". 1080i uses interlaced scanning, like primary Tv, which alternates sending odd lines and even lines and thus sends a perfect picture 30 times per second. 1080i provides the highest possible resolution, but has the same request for retrial rendition as primary Tv.

1080p High Definition Dvd

Your next Dvd player will most likely be able to play 50 Gbyte Dvd's that will use an High Definition Multimedia Interface (Hdmi) that will also provide up to 7 channels of high definition audio along with the 1080p image. This is speedily becoming the accepted for Dvd movies in the same way that Dvd substituted Vcr tapes a few years ago.

To view these movies you will need an Hdtv display with Hdmi inputs and a Dvd player capable of playing the new format with Hdmi output. You will also need extra Hdmi cables to join together the two. Your cable or satellite victualer will also use Hdmi connections so you will need at least two Hdmi connectors on your display device.

There are some drawbacks to the current models of High Definition Dvd players. High- bandwidth Digital article security (Hdcp), creates a slow down when starting a movie, you may think that you have a qoute with your Dvd. The player is just talking to the display expedient to make sure that they are both licenced properly. Unless you are viewing the Dvd on a 42 inch or larger screen you will have a hard time telling the contrast between 720p and 1080p.

Broadband what does it mean?

You may be using broadband now and not even perceive it. How often do you opt an online movie from your local cable or dish company? Have you noticed how many high definition features are now being offered? As the selections come to be larger, watching streaming article will come to be so base that we will slowly forget about our Dvd players. 720p is very base and soon 1080p will also be available. The security for the movie producers is already there as the high definition boxes use Hdmi with Hdcp for the high definition outputs.

Organic Light Emitting Diode (Oled) Tv's

Then comes the Oled's, we are already using them on the new cell phones and laptops. The first Oled television was introduced in 2008. As query for larger displays increases and the pipeline that is now full of plasma and Lcd screen began to empty we will hear more and more about the color capability of the Oled's. For a few years the resolution of the displays will remain about the same and the sales pitch will be all about the colors. But keep in mind that there is no limit the size of the screen with Oled and it is also flexible. The flexibly will allow for easer handling and installation.

As the size of the screen increases a query for greater resolution will start all over again. And with the flexibly comes the possibility of 360 degree wrap-a-round screens. Remember that the horizontal resolution is much easer gather than the vertical so a resolution of 16000(or greater) X 1080p is not out of the question. 360 degree movies are not new, Disney World has had one in doing in Orlando for years. You stand in the town in a large group and turn colse to to consequent the action. A few spinning recliners and the screen raised a few feet and away you go.
