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: An embodiment of a method of requesting a plurality of media streams can include, as performed by a computing device, receiving a control input to control a playback function of at least one of the plurality of media streams, determining a download bandwidth between the computing device and a media source on a network, classifying the at least one of the plurality of media streams based on the control input and total download bandwidth, and sending a plurality of requests for the plurality media streams over a single connection to the media source, wherein at least one of an order or a content of the requests is based on the classification. The sending of the media stream requests can utilize at least one of a server-side protocol for multiplexing media streams over a single connection or one or more of HTTP pipelining or HTTP range requests over a single connection.

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.
