Abstract
Performing a real-time application on a mobile device, involving communication of audio/video packets with a remote device. The mobile device may initially communicate the audio/video packets on a first communication channel with the remote device. During the real-time communication, the mobile device may determine if no packets have been received by the mobile device from the remote device for a first threshold period of time. If no packets have been received by the mobile device from the remote device for the first threshold period of time, the mobile device may establish a second communication channel for transmission of the audio/video packets with the remote device. In response to using the second communication channel, the mobile device may modify a resolution or bit rate of the audio/video packets transmitted to the remote device.
