A system and method is provided for controlling multimedia data transmission to a communication device via a network. The system comprises a de-muxer configured to obtain a first multimedia data for transmission and a flow controller configured to evaluate an estimated buffer time associated with the communication device. If the estimated buffer time satisfies a first threshold condition, the flow controller updates a current transmitting state to be a pacing state. And if the estimated buffer time satisfies a second threshold condition, the flow controller updates the current transmitting state to be a bursting state. The system also comprises a muxer configured to transmit the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.

Methods and systems for optimal delivery of internet video over wireless networks

A method includes receiving streaming media data having an original media frame and an original frame index referencing the original media frame; determining an optimal session bitrate, wherein the optimal session bitrate is based on the available network bandwidth between a server and a terminal; allocating a frame budget for an output media frame by estimating a frame size of the output media frame based on the original frame index and the optimal session bitrate; generating the output media frame by processing the original media frame based on first encoding parameters and, if the allocated frame budget is greater than a frame size of the processed media frame, padding the processed media frame; and providing the output media frame.

Adaptive bitrate management on progressive download with indexed media files

A method including receiving a receiver report from a terminal; estimating one or more network conditions of a media network based at least in part on the receiver report; determining an optimal session bitrate based on the estimated one or more network conditions; and providing media data to the terminal based on the optimal session bitrate.

Adaptive bitrate management for streaming media over packet networks

A computer-implemented method including receiving streaming media, wherein the streaming media is requested by a media player at a mobile device; retrieving timing information from the streaming media, wherein the timing information corresponds to real-time playback rate on the media player; framing the streaming media based on the real-time playback rate on the media player; scheduling transmission of the framed streaming media based on the framing; and transmitting the framed streaming media to the media player according to the schedule.

Method for controlling download rate of real-time streaming as needed by media player

A method including providing pseudo-streaming media data to a terminal; receiving a transport control protocol (TCP) acknowledgement from the terminal; estimating one or more network conditions of a network based at least in part on the TCP acknowledgement; determining an optimal session bitrate based on the estimated one or more network conditions; and providing pseudo-streaming media data to the terminal based on the optimal session bitrate.
