In the new digital era, where technology advances rapidly, manufacturers have found a new way to combine the two top-rated electronic products in the global market: mobile phones and TVs. The digital generation demands communication and entertainment all in one device. No need to miss news, sporting events, movies and TV shows anymore just because you cannot be in front of a TV. The mobile Digital Television (DTV) is here to make your life easier and enable you to watch in real-time any broadcast you are interested in, anytime, anyplace.
South Korea was the pioneer country that developed mobile DTV technology back in 2005. Originally, TV signal was transmitted through a satellite and a terrestrial DMB service but, one year later, 3G networks were used to replace them. Since then, United Kingdom, Germany and Italy tried to initiate the use of mobile DTV but soon, all efforts were deserted. Currently, in the US, Verizon Wireless and AT&T are supporting mobile DTV.
Nowadays, broadcasters are trying to include mobile DTV to most handheld devices, from mobiles to PDAs. Using the digital television spectrum as the primary technology, manufacturers have succeeded to broadcast images and sound via digital signals instead of analog ones that are used to conventional TVs. This way, anyone with access to a Wi-Fi hot spot or a 3G connection is able to watch any TV program on their mobile phone with no limitation. Digital signal allows users to enjoy crispy clear sound and high resolution videos wirelessly.
With mobile DTV, users are not only able to watch live broadcasts but also to save their videos and movies or live stream to their phone’s memory. More or less, users can actually use their mobile as a personal computer to download video events, news clips or even full television shows. Mobile DTV via the 3G or Wi-Fi networks is fully capable of supporting personal video recording, while custom cellular networks are not.
Even though mobile DTV is the future, still not all handheld devices support this feature. Therefore, consumers have to seriously consider several factors before purchasing a particular device. Specifically, in order to fully enjoy a broadcast, the mobile under consideration should feature a wide LCD screen to enhance clarity and colors. iPhone is considered to be the pioneer device when it comes to mobile DTV as its 3.5″ wide touchscreen enables users to enjoy any live broadcast. Besides, power consumption is also an issue as mobile DTV literally drains the phone’s battery. So it either best to purchase a mobile with a long lasting battery or buy a spare one.
Overall, mobile TV is evolving rapidly and live programming can be distributed over standard cellular networks. Although it consumes extended transmission bandwidth, the new technologies developed are addressing this problem and are progressively solving the broadcasting issue.
