                                                           Shaping the Future of TV

     Nobody can predict the future of TV with any certainty but some major figures in the industry have

recently put forward their thoughts on what will shape TV of the future.

     The shaping of a personalized television future is starting to take place, says Intel. The chip giant,

who makes the processors found in most personal computers, states that by 2015 there will be just over

12 million devices using IPTV services that will be capable of connecting to over 500 billion hours of TV

& video.

     This supports the idea to make television a more social, personalized and readily accessible device

available anywhere through IPTV services. As more and more people consume TV & video through various

mediums, there is now a greater need to distribute and manage this content.

     As such, companies like TV Genius are accepting this announcement made at Intel's Developer Forum

(IDF) in the USA by their chief technology officer, Justin Rattner.

     With such a variety of content likely to become available, technology firms will need to assist in making

personalized TV recommendations more readily accessible.

     Mr. Rattner, speaking to the BBC said, "TV will remain at the centre of our lives and you will be able to

watch what you want and where you want. We are talking about more than one TV-capable device for every

man and woman on the planet. People are going to feel connected to the screen in ways they haven't in the

past."

     One way in which this will happen will also be assisted by a more united service of material combining

including video content, internet content, broadcast content, and personal content.

     This content will become much more accessible through remote devices like mobile phones using IPTV

technology. This means that users will be able to watch their favorite programs away from the traditional

media hub, the home.
