ADAPTIVE BITRATE MANAGEMENT ON PROGRESSIVE DOWNLOAD WITH INDEXED MEDIA FILES

摘要

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.
