Internet Television
Computers are used largely for surfing the web, while televisions are used for infotainment.
This distinction may soon be over as a new breed of machines has been developed that combine the two functions Internet Television is here.
Sony and Google have entered into a partnership to produce internet TVs, which will allow you to watch televisions as well as use the TV screen as a Computer Screen simultaneously. The latest HD television series announced by Sony comes with Internet Connectivity, Wi-Fi, USB Ports, DLNA, built-in storage and other bells and whistles. If one is surfing the web, then the TV screen become a smaller inset in the main screen so that the words are large enough to be easily read.
3D Televisions
I remember seeing the first 3D film House of Wax on Youtube. almost 2 Years back. It appeared at the time to be the beginning of new era of 3D movies but it has taken about 50 Years for the revival of 3D Movies, and now 3D TV is also here.
There have been rapid recent developments in the field of 3D television. A Scottish inventor David Brewster first developed the 'Stereoscope' that allowed 3D photography. A common method for making the 3D videos is to use two different cameras to record a scene, with cameras being placed at the same time from one another as the distance between a person's eyes. The two images are accurately superimposed, and when projected and viewed on a screen, a 3D effect is produced as each of the two eyes sees the object from a slightly different perspective. Arrays of multiple cameras can also be used for image capture. Hectic efforts are underway by a number of TV manufactures such as Sony, Panasonic, LG etc, to develop high quality 3D TVs. Since the viewers need to wear special glasses, this is a drawback as the glasses can be cumbersome and expensive.
Toshiba launched its 21inch 3D TV in April 2010 which does not require any special glasses for viewing, but the 3D effect works only with in a narrow viewing range. Sony has also announced its plans to launch a 3D TV without the glasses soon. The Helium 3D system being developed by a consortium of companies, the 'Wedge' system developed by Microsoft, and a number of other systems under development will allow a wider viewer angle with 3D effects.
The 3D TV war is heating up!
