Abstract
This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. The network (104) is comprised of at least a transmitter device (110) and a receiving device (112). The controllers (122) and (126) of these devices handle the exchanging of configuration messages between the devices (110) and (112). Using the invention, the user is not required to manually configure the processor to receive media packet streams. Instead, a controller (126) of a receiving device (112) operates to receive information on a user selection of media channels and automatically configure the processor of the transmitter device. Further, the receiving device (112) is able to receive media channels using both unicast and multicast protocols. Media channels can be given textual labels which are unique on the unique (104) and easily identify to the user the actual source of the media channel. Media channels of different formats to be sent on the same net work simultaneous. Further, redundant media channels are easily accommodated.
