Abstract

A transceiver including, a codec, microcontroller, and radio. The codec including an analog to digital converter for receiving a first audio program and converting it to a first digital signal; a digital to analog converter for receiving a second digital audio signal and converting it to a second audio program; and, a control function for managing characteristics of the codec. The microcontroller is in electrical communication with the codec: for receiving the first digital audio signal from the codec and packetizing it into a first packet for transmission over a TCP/IP network; for receiving a second packet from network and converting it into the second digital audio signal and sending it to the codec; and for receiving control signals from the network. The radio is in electrical communication with the microcontroller for connection to the network to transmit the first packet to the network and receive the second packet from the network.

Claims
