Television stations and broadcasting cooperatives in Berkeley transmit programs over terrestrial television. They can be by analog television signals, or more recently, by digital television. The television broadcasting standards are set by the government. The stations procure license from a government agency defining the geographic area that the station is limited to and allocating the broadcast frequency for the station’s transmissions, also placing limits on what types of programs can be broadcast. This also requires the station to broadcast a minimum amount of certain programs.
