digital dividend

Digitization allows much more information to be transmitted in a fixed frequency spectrum than with analogtransmission. For example, analogTV channels have a bandwidth of 6 MHz. If this bandwidth is used for digitalTV, then six to eight digital TV channels can be transmitted in the 6 MHz wide channels. The higher frequency efficiency frees up many TV channels in the upper UHF range. These freed-up transmission frequencies, known as white spaces, are the "digital dividend" that can be used elsewhere, for example for broadband in the access area. Many radio and television programs are still transmitted in analog form by terrestrial means in the VHF and UHF ranges. For example, 56 MHz is available for analog broadcasting in the VHF range and 392 MHz in the UHF range. Based on the higher transmission density for digital broadcasting and digital TV, the EU Commission estimates the additional available frequency
