Learn About How TV Smartphone Work

TV phones have been a long time coming for most of us. Whilst TV enabled cell phones have been online in Korea since early 2002, we are really only now starting to see their widespread availability in the western world. The quality of these early TV streams was poor, and the costs restrictive. This was due to their transmission over standard cellular networks. Other limitations centered on the rapid draining of battery life for the individual handsets. However, since the power houses of Samsung and Vodafone became involved, the industry has benefitted from improvements across the board. The technology that TV phones use is a relatively simple concept to understand: TV signals are no more than any other radio signal, which cell phones pick up all the time. Working in much the same way as a home TV, the phone extracts all audio and video content from these signals, and displays them as a TV picture on the handset's screen. Some challenges do still exist however; a fast transmission speed is required, whilst bandwidth usage is high. This was a real stumbling block before the third generation phones were introduced. However, as advances in mobile technology continue, TV phones for the masses are becoming viable. Data transfer rates are now up to 2 megabits per second, whilst 3G technology can deliver TV streaming using multicasting - which saves significantly on bandwidth usage. Transmitting companies too are using new techniques to save on battery life; by reducing the time the receiver needs to be active by transmitting signals in bursts. As with all new technologies, there are still problems to be ironed out; however some early exponents of the technology are offering TV service plans subscriptions right now. If you are interested in getting TV streamed to your cell, check out the offerings from such operators as Sprint TV, MobiTV or SmartVideo. With many different packages to choose from, many operators have signed exclusive deals with the likes of CNN, Disney and the NFL, to bring you many favorite broadcasts. Existing phones can be converted to receive TV streaming, though with the launch of the iPhone, and the latest generations of Blackberry's, this technology is now becoming fitted as standard. TV phones are the way mobile connectivity is headed, and the constant development of the industry is just the latest in satisfying the need to stay in touch with the world 24/7. china cell phones from http://www.agoodic.com
