The mobile TV is powered by DVB-H, which stands for Digital Video Broadcasting Handheld. The DVB-H is an adaptation to an environment of mobile DVB-T, Digital Video Broadcasting Terrestrial, which is popularly also known as DTT.
One of the most important reasons why it is necessary to adapt the DTT and create the DVB-H is to regulate energy consumption in the receivers. It is not the same as having the TV connected to the mains to go with a mobile phone battery power consuming.
It is also necessary to adapt the quality of the received signal which can be viewed on a mobile screen, which usually has much less resolution than a standard television. One of the great advantages of DVB-H is compatible with DVB-T is that you can use the same frequency band to issue two, so that the strings do not need an infrastructure change as great as when you pass from analog to digital television.
We're talking all the time in the mobile TV though, more properly speaking, we should say mobile TV, since not only the phones will be able to receive the signal, but any other wireless device, such as TVs on buses, even if certain to be seen in the mobile will be their way of more widespread use.
One important thing to know is that, due to the operation of this technology can be a little slow in changing the channels, taking between 1 or 2 seconds. Although not a very high time, if that is larger than the usual we're used to our TV.
The biggest advantage is the freedom to enjoy TV wherever you are. For example, catch the latest news while traveling by public transport to work. Broadcasting services on mobile are generally complementary to those offered to the so-called third generation mobile. Since 2004, when they broke into the market the third generation mobile and can watch news, cartoons or music videos on these devices.
In this case the Live TV on Mobile technology is based on a point to point link that allows downloading of audiovisual content when the user decides. By contrast, with the DVB-H the same content is distributed to all users connected simultaneously using multi point links, in the same way that conventional television does.
