Abstract: In the described embodiments, a connection data exchange (“CDX”) service serves as an exchange point for connection data for establishing peer-to-peer (“P2P”) connections between devices. During operation, the CDX service can receive a connection data structure (a “ticket”) that was created by a matchmaker or an invitation service in response to requests from devices attempting to establish P2P connections. Each ticket can identify a corresponding device and can include encrypted NAT hole-punch data associated with the corresponding device. The CDX service can authenticate each ticket and decrypt the NAT hole punch data from the ticket using a corresponding key. The CDX service can then use corresponding NAT hole punch data to send connection data to each of the devices that reside behind NAT devices.

Abstract: Computing devices may implement dynamic transitions from video messages to video communications. Video communication data for a video message may be received at a recipient device. The video communication data may be displayed as it is received, and recorded for subsequent playback. An indication of a selection to establish a video communication with the sender of the video message may be received, or an indication that display of the video communication is to be ceased may be received. If a video communication is to be established, then a video communication connection with the sender of the video message may be created so that subsequent video communication data may be sent via the established connection.

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.

Abstract: Some embodiments provide a method for initiating a video conference using a first mobile device. The method presents, during an audio call through a wireless communication network with a second device, a selectable user-interface (UI) item on the first mobile device for switching from the audio call to the video conference. The method receives a selection of the selectable UI item. The method initiates the video conference without terminating the audio call. The method terminates the audio call before allowing the first and second devices to present audio and video data exchanged through the video conference.

Abstract: A method for detecting and recovering from a transmission channel change during a streaming media session is disclosed. The method can include a wireless communication device detecting a stall condition resulting from a transmission channel change. The method can further include the wireless communication device capturing a snapshot of a current transmission parameter state of the streaming media session in response to detecting the stall condition. The method can also include the wireless communication device using the snapshot to restore the streaming media session to the transmission parameter state captured by the snapshot following completion of the transmission channel change.

Abstract: Some embodiments use several different types of networks to relay several different types of media content among several different computing devices. The media content of some embodiments is data that a computing device can process in order to provide a presentation of the media content to a user of the device. Examples of types of such media content include audio data, video data, text data, picture data, game data, and/or other media data. In some embodiments, two different networks relay media content of two different types among multiple computing devices. Specifically, in some embodiments, a first network routes among the computing devices one type of media data content (e.g., game data), while a second network routes among the computing devices another type of media data content (e.g., audio and/or video data of game participants). The two networks differ in some embodiments based on their topology.
