TV mobile phones were released in Japan in 2001 but the reception of the program was awful and it drank up all of the phones battery. But mobile phone networks are currently working on producing a high quality DTV mobile phone.
Like TVs, mobiles recieve radio signals, in the case of mobile TV they have the ability to receive radio signals in the TV-allocated frequency bands aswell as the bands allocated for mobile phone voice data.
However, there are a few issues that are going to have to be considered. Video streaming need fast transmission speeds, previous "2G" GSM networks provided data-delivery speeds of 10 to 14 kilobits per second (Kbps), and "2.5G" networks offered 30 to 100 Kbps. At 10 Kbps, a TV show is really a slide show; and at 100 Kbps, it's pretty choppy.
Another issue to think about is bandwidth. TV data takes up a lot more space than voice data and delivering a TV signal to thousands of phones is going to really slow down the network.
Finally, receiving a TV signal on your mobile is going to use up your battery extremely fast.
