    Abstract: Some embodiments relate to a device that transmits/receives encrypted communications with another device. A first device, such as a smart phone or smart watch, may generate a message associated with a certain data class, which may determine the security procedure used in the communication of the message. The first device may establish an encryption session for the purpose of communicating the message to a second device. Prior to sending the message, the first device may wait until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the data class of the message. Similarly, after receiving the message, the second device may not be able to decrypt the message until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the message data class.

    Abstract: A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence.

    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: Conducting a real time application between a mobile device and a remote device. A first one or more messages may be transmitted to the remote device to establish a primary channel of communication for the real-time application. The primary channel may use a first radio access technology (RAT), such as WiFi or a cellular RAT. A second one or more messages may be transmitted to the remote device to establish a secondary channel of communication for the real-time application. The secondary channel may use a second RAT that is different from the first RAT. Data of the real-time application may be transmitted over both the primary channel and the secondary channel in a concurrent or redundant fashion.

    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: Computing devices may implement dynamic detection of pause and resume for video communications. Video communication data may be capture at a participant device in a video communication. The video communication data may be evaluated to detect a pause or resume event for the transmission of the video communication data. Various types of video, audio, and other sensor analysis may be used to detect when a pause event or a resume event may be triggered. For triggered pause events, at least some of the video communication data my no longer be transmitted as part of the video communication. For triggered resume events, a pause state may cease and all of the video communication data may be transmitted.
