Patent ID: 8050203

Claim:
A system for wireless transmission of audio signals, said system comprising a single transmit node and one or more receive nodes, wherein: (a) the transmit node comprises one or more radio frequency transceivers adapted to send one or more audio signals in digital form; (b) each receive node comprises a radio frequency transceiver adapted to receive digital audio signals from the transmit node; (c) the transmit node is adapted to retransmit previously sent audio data in response to a request from a receive node; (d) each of the transmit node and the receive nodes incorporate a single hardware-multithreaded processor having eight or more hardware threads, said processor being adapted to implement baseband functions, protocol functions, error correction functions, and audio processing functions in parallel on each node; (e) end-to-end audio signal latency may be preset to a desired value, and will remain substantially equal to the preset value during and between operational sessions; (f) two or more processors run software which implements a duplex control channel between the transmit node and one or more of the receive nodes, thereby enabling meta data to be sent on the same physical radio medium that transports the audio signal; and (g) said duplex control channel is used to transport control information which has been received by an optical receiver at the receive node and which is rebroadcast by an optical transmitter at the transmit node.
