Digital Terrestrial Television

Thus, the size of a video image moves from approximately 800 600 pixels (the current system) to 2,000 x1000 pixels. Full HD is the famous, 1,000 lines of resolution. It should be noted also defined an intermediate system, with a resolution of 1 megapixel. (1400 x 800 pixels, approx.) Are studied, and new resolutions and larger image sizes, up to 4 mega-pixels, but is unlikely to see the light in the domestic market, because to enjoy high-definition is necessary to have adequate equipment. Can we see high definition? To qualify it is necessary to have a TV ready for such decisions. That is, a Full HD TV (capable of displaying on the screen 2-megapixel, or images of 2000 x 1000 pixels), or an HD Ready TV capable of displaying 1 megapixel.

(Recall that the old system is 0.4 mega-pixels, and the more resolution, better image quality) A current problem is that virtually any TV network broadcasts in HD. Only one satellite pay channel does. Therefore, despite having a modern television ready for high definition, we can not see the television broadcasts of the conventional channels in HD, and not issued with that quality. It should also be noted that the implementation of DTT is namely the Digital Terrestrial Television, is not going to broadcast in HD. Simply change the broadcast system, but not the resolution or image size. It will look better because it will be digital (Like a DVD is better than VHS) but it will not be high definition.

Today there is no clear timetable for conventional broadcast channels in HD. So to see something in HD, the clear choice is to make it through the Blu-Ray. The Blu-Ray is the successor of DVD. Its main feature is that this time yes, it is in HD. If you connect a Blu-Ray player to a TV HD Ready or Full HD we can finally enjoy the incredible picture quality of High Definition content. Then enough to buy a Blu-Ray (which are dropping dramatically in price, already, in March 2009, for 300 Euros), connect the TV and put a Blu-Ray. Some of the latest video game consoles (PS3) incorporating a high-quality video players definition. Is this it benefit my company? For a company, the advantage of making a video in high definition is obviously that you can project it on a Plasma or LCD TV with much higher quality (up to 4 times) using a Blu-Ray. It is ideal therefore for playback at fairs, and generally on large screens (halls, presentations, meeting rooms, etc..) Little by little, the Blu-ray will also widespread in the computing environment, with frequent and see notebooks with this technology, so in the near future productions will normally deliver in this format. Has made the leap in 2007 with the High Definition production, with more than a year to complete preparations for the production of corporate content in HD, either to deliver them into Blu-Ray or Web pages through the new Codecs WMV HD or H.264.
