    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: A method for refreshing blocked media packets for a streaming media session over a wireless network in a stall condition is disclosed. The method can include a wireless communication device maintaining a buffer at an application layer. The buffer can contain at least a portion of media packets provided to a baseband layer by the application layer for transmission. Media packets provided to the baseband layer can be queued in a baseband queue prior to transmission. The method can further include the wireless communication device generating at least one new media packet for the streaming media session during the stall condition; flushing at least a portion of the media packets queued in the baseband queue; and replenishing the baseband queue by providing the baseband layer with at least a portion of the media packets contained in the buffer and at least one new media packet.

    Abstract: Systems and methods are disclosed for the rendering of contents communicated between devices. A source device processes a video sequence and transmits it to a target device together with metadata including rendering directives. At the target device, the received video sequence is rendered according to the rendering directives. Rendering is affected by events detected by the target device at the time of rendering or by the target device's information. Transparency masks, generated by the source device, are transmitted in an alpha channel to the target device, and are used for blending the video sequence with a secondary content.

    Abstract: An apparatus and method for detecting and analyzing spikes in network jitter and the estimation of a jitter buffer target size is disclosed. Detected spikes may be classified as jump spikes or slope spikes, and a clipped size of detected spikes may be used in the estimation of the jitter buffer target. Network characteristics and conditions may also be used in the estimation of the jitter buffer target size. Samples may be modified during playback adaptation to improve audio quality and maintain low delay of a receive chain.

    Abstract: A method for adaptive audio codec selection during a communication session is disclosed. The method can include negotiating a set of audio codecs for use during the communication session. The method can further include defining multiple audio tiers. Each audio tier can be associated with a network condition and can define an audio codec from the set of audio codecs for use in the associated network condition. The method can also include using a first audio codec during the wireless communication session. The method can additionally include determining a changed network condition selecting a second audio codec by determining the audio tier corresponding to the changed network condition. The method can further include, in response to the changed network condition, switching from the first audio codec to a second audio codec that is defined by an audio tier having an associated network condition corresponding to the changed network condition.
