Audio video system with embedded wireless host and wireless speakers

Abstract

An audio video system is described that includes an AV receiver with a wireless audio module (WAM) host and without audio amplifier functionality. The system further includes a plurality of wireless speakers each having a WAM device to enable unidirectional or bidirectional communications with the WAM host. Each wireless speaker includes an amplifier that may be matched to a driver of the speaker to optimize the frequency response of the driver.

What is claimed: 
     
         1 . A system, comprising:
 an audio video (AV) receiver with a wireless audio module (WAM) host and without a centralized audio amplifier functionality, the WAM host being implemented using a point-to-multipoint network topology using an Ultra-Wideband (UWB) host/device architecture,   the WAM host including
 a first microprocessor, 
 an audio-in first-in-first-out (FIFO) buffer coupled with a digital audio input, the audio-in FIFO coupled with a first input and a first output of the first microprocessor, 
 a first packet memory operative for packet storage and coupled with an output of the first microprocessor, and 
 an UWB host coupled with an output of the first packet memory and bi-directionally coupled with the first microprocessor, the UWB host operative to wirelessly transmit digital audio received on the digital audio input; and 
   a plurality of wireless speakers each having a WAM device configured for bi-directional communication with the WAM host over a wireless link between each WAM device and the WAM host, wherein each wireless speaker includes an amplifier to amplify communications received from the WAM host and to which at least a part of the centralized audio amplifier functionality is distributed,   each WAM device including
 an UWB device operative to wirelessly receive the digital audio transmitted by the UWB host, 
 a second packet memory operative for packet storage and coupled with an output of the UWB device, 
 a second microprocessor bi-directionally coupled with the UWB device and with an output of the second packet memory, and 
 an audio-out FIFO coupled with a second input and a second output of the second microprocessor, and the audio-out FIFO coupled with a digital audio output operative to output digital audio.
