Embodiments relate to a system and a method for a redundant real-time wireless receiver network. A Remote Digital Antenna Digital Receiver ('RDADR') is coupled to multiple Remote Digital Antenna ('RDAs'). The RDADR and the multiple RDAs are coupled via a digital bus. The multiple RDAs attempt to receive one or more digital signals from a transmitter. If the one or more digital signals are received without an error by one of the multiple RDAs, the RDA that received the one or more error-free digital signals sends the digital signals to the RDADR using the digital bus. The redundant real-time wireless receiver network provides a reliable and fault tolerant system to deliver digital audio signals in real-time.

System and method for a redundant real-time wireless receiver network

Disclosed is a system and method for the real-time wireless transmission of digital audio signals. A transmitter including a processor may be used to: generate a first digital data stream and a second digital data stream from a digital audio signal and transmit the first digital data stream at a first radio frequency and the second digital data stream at a second radio frequency. A receiver including a processor may be utilized to: receive the first and second digital data streams at the first and second radio frequencies, respectively, and generate the digital audio signal from the first and second digital data streams.

System and method for real-time wireless transmission of digital audio at multiple radio frequencies

Disclosed is a system and method for the real-time wireless transmission of a digital audio signal and control data. A transmitter may be coupled to an audio source. The transmitter includes a processor to combine control data with a digital audio signal from the audio source and the processor wirelessly transmits the combined control data and digital audio signal to a receiver. The receiver includes a processor that is used to receive the combined control data and digital audio signal and to process the control data to perform a user pre-defined function.

System and method for real-time wireless transmission of digital audio signal and control data

A technique for reducing inherent noise in a real time digital audio wireless system. The technique allows for low power stereo analog to digital and digital to analog converters to be used in a battery operated real time digital audio wireless applications. The audio signal is sent to the left and right channels of an analog to digital converter with a preceding audio amp of different gain at the input to each channel. The signals are simultaneously digitized then combined to generate a new digital value resulting in noise reduction at lower amplitudes. This new data word is then transmitted via radio waves to a digital audio receiver. Once the data is received it is output simultaneously to a stereo digital to analog converter. The digital to analog conversion of both left and right channels is then summed using a resistor network and an audio amplifier. The audio amplifier output is then reduced to create further reduction of noise at all amplitudes.
