This is a vast improvement over the old analog signals, which required separate streams of transmission. Oddly enough, some DVB-T transmissions take place over analog networks, with the antennas and receivers getting some helpful technological upgrades along the way. It's not just television sets that can receive signals broadcast using DVB-T. Computers can be the recipients of such signals as well. Computer users must purchase a special adapter in order to receive DVB-T, but the adapter is widely available. DVB-T signals can be received on single computers or on networks, depending on where the adapter is attached. DVB-T is not the only DVB out there.

This is the data transmission method used for mobile TV, which will no doubt be part of the future of broadcasting...
