Receivers are electronic devices which detect, demodulate and amplify transmitted signal, and convert the signal format into a format for video, voice or data. Information is transferred from a starting location to a destination by first converting the information from a parallel format to a serialized format. Then, the serialized information is transmitted as a data stream across a transmission medium such a
coaxial cable, a twisted pair cable, or a
fiber optic cable, to the destination. At the destination, a receiver receives the data stream, and processes it to convert the information back into a parallel format. In a digital broadcast, a digital video signal and an audio signal are compressed corresponding to the MPEG2 format. To receive the full benefits of digital audio broadcasting, listeners must have a digital audio receiver to receive the digital audio broadcast. When a digital broadcast is received, an IRD (integrated receiver decoder) is connected to a receiver. The IRD selects a signal of a program that the user desires and decodes the selected signal into a video signal and an audio signal. A radio receiver includes a plurality of
antenna elements for receiving a radio signal from a radio
transmitter.
