Abstract
A wireless personal-area network (PAN) communication system includes a first device configured to simultaneously transmit a digitized stereo audio signal to and receive a digitized voice signal from a second device over the wireless PAN. The system also includes the second device, which is configured to simultaneously receive the digitized stereo audio signal from the first device and transmit the digitized voice signal to the first device over the PAN. The wireless PAN can be a Bluetooth® network. Low-latency audio codecs may be included in the first and second devices to reduce the latency of the voice and stereo audio signals transferred between the devices.

16. A method of wireless communication between two devices connected over a wireless personal-area network (PAN), comprising:
-
establishing an upstream Bluetooth®
A2DP connection between a first device and a second device on the wireless PAN;establishing, concurrently with the upstream Bluetooth®
A2DP connection, a downstream Bluetooth®
connection between the first device and the second device on the wireless PAN, the downstream Bluetooth®
connection being separate from the upstream Bluetooth®
A2DP connection;transmitting a digitized stereo audio signal from the first device to the second device over the upstream Bluetooth®
A2DP connection; andtransmitting a digitized voice signal from the second device to the first device over the downstream Bluetooth®
connection. - View Dependent Claims (17, 18)
