A Brief Look At Mobile Phone TV
The devices come in all sizes and modes of operation to achieve about the same purpose. The signal received may be courtesy of a pay TV broadcast or one of the many free to air transmissions. In either case, the format of propagation used has to be synchronous with that of the receiving end.
The pioneering product was called a microvision released in the late seventies. Though it had a strong receiver that allowed it to work even across borders, it did not gain much popularity among the masses. Though portable, it was relatively bulky since it employed a cathode ray tube screen. It was quite small in size and could be carried around in the pockets.
Today some 3G phones provide TV as one of their features. At the summit of this relatively uncharted sector of modern commerce are Japan and South Korea. These have established specialized satellite networks to facilitate transmission formats for their products.
The fast spreading frenzy has spread to other regions notably Europe and America. The fever has influenced changes in conventional broadcasting, with mobisodes replacing normal episodes for the special clients. Some service providers have coerced with some stations to transmit the signals.
The greatest challenge to the key players in mobile phone TV is the devising of more efficient power sources. It has also been realized that mobile TV would be better if the gadget was incorporated with more buffers. The user interface development has also been a major hurdle in these devices.
