Abstract: An audio gateway device may establish a wireless connection between the audio gateway device and the hands free device using a protocol supporting a single subscription. The audio gateway device may also establish a first call which terminates or originates at the hands free device via a first subscription. An outgoing call may be established via a second subscription by: (a) receiving a first indicator from the hands free device to switch subscriptions, where the first indicator does not specify a subscription; and (b) establishing an originating second call via the second subscription which originates at the hands free device. Similarly, an incoming call may be established via the second subscription by: (a) sending a second indicator to the hands free device of an incoming third call, where the second indicator does not specify a subscription; and (b) establishing the third call via the second subscription which terminates at the hands free device.

Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.
