As you may be looking at updating your current freeview box or tv because of digital switchover Hassan Whiteside Jersey , it’s worthwhile to learn what technology is on the market and open to you. It is worth reviewing your entire TV equipment if you are going to need to get a brand new freeview box anyway and you will probably quickly realise there’s additional alternatives besides investing in a brand new freeview box.
3D TV will be the next big revolution in your own viewing experience. There are already channels on satellite stations especially live sport that is typically shown in 3D as standard on Sky now. The BBC produced Wimbledon in 2011 in three-dimensions and that was on Freesat (the free satellite TV service). Therefore it’s possible that 3D will soon be available through a freeview box.
Freeview Box – 3D TV Principles
The standard method that all 3D television operates (and this is true whether you’re already using a freeview box or not) is that each eye sees the same image but from a slightly different angle, as in actual life, and this causes your brain to interpret the picture into a three-dimensional object. This happens at such a rate that you don’t conceive it occurring but if you’ve watched a programme without the glasses on, you will see the slightly different coloured and blurry images. That is because both images for each eye are on the tv screen at the same time.
Freeview Box – 3D Glasses
There’s two kinds of glasses to view with : Active and Passive. The traditional red and blue glasses are the passive type and are the kind found in cinemas. Active is the new type that come with 3D televisions. They’re electronic and synchronise with the tv screen. More on that later.
Passive glasses work as each eye filters out either the blue or red image that means each eye receives a slightly different image. Your brain translates that into a 3D image. Since these glasses are so cheap to make they are the primary choice of cinema chains.
Active glasses operate slightly differently. They open and shut the lens on the glasses for each eye in order left, right, left Dion Waiters Jersey , right. This is synchronised with the tv screen so that it knows which picture to display whenever for example the left eye is open. That may sound like it wouldn’t work but it occurs at typically 120 times per second. Due to the speed at which the screen changes, plasma tvs are favored to LED ones as they can adjust their image more rapidly than an LED which tends to ‘bleed’ the colour to alter picture.
Freeview Box – What Else?
Having bought a 3D television is not sufficient on it’s own. You require a source attached to the box to generate the correct images. The passive style is starting to become more widespread and will start appearing more on terrestrial channels too so any freeview box, especially a freeview box HD, should work fine in that instance. The active style requires a 3D capable blu-ray player attached to your screen to make it work correctly since it has to give instructions to the screen and the glasses whilst the film is playing. At present a freeview box will not offer that kind of 3D.
Freeview Box Summary
In other words, consider all this if you are looking to obtain a new freeview tv or upgrade any of your television equipment as well as your freeview box.
