Abstract:
1. A wireless USB audio transceiver comprising: a port configured to exchange data via a USB communication channel with a host computing device; a wireless transceiver configured to receive and transmit wireless signals, the wireless transceiver comprising: a multiple mode transmitter configured transmit the wireless signals at multiple data rates; a first data path associated with a first audio function, the first data path configured to transmit audio data transmitted from the port to the wireless transceiver; a second data path associated with a second audio function, the second data path configured to transmit audio data transmitted from the wireless transceiver to the port, the first audio function and the second audio function being independently controlled via a first control interface and a second control interface, respectively; and an audio signal detector configured to determine the presence of the audio data on at least one of the first and the second data paths, the audio signal detector also being configured to monitor data activity in a buffer associated with an endpoint in data communication with the first data path or the second data path, wherein the data activity is configured to indicate whether microphone data is streaming via the second data path, wherein the multiple mode transmitter is configured to transmit the audio data at one of the multiple data rates as a function of the presence of the audio data on one or both of the first and the second data paths.
