MULTIPLE LOGICAL REPRESENTATIONS OF AUDIO FUNCTIONS IN A WIRELESS AUDIO TRANSMITTER THAT TRANSMITS AUDIO DATA AT DIFFERENT DATA RATES
Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and computing devices. More specifically, the embodiments related to structures and techniques for implementing multiple logical representations of audio functions in a wireless audio transmitter, such as a USB dongle configured to transmit and to receive audio data wirelessly via, for example, a Bluetooth link. In one embodiment, a wireless USB audio transceiver can include a multiple mode transmitter configured transmit wireless signals at multiple data rates. Further, the wireless USB audio transceiver can include a first data path modeled as a first audio function, and a second data path modeled as a second audio function. Also, included is a signal detector configured to determine the presence of the audio data on a data path for modifying transmission data rates as a function of the presence of the audio data.
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,
wherein 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.
