METHOD FOR BANDWIDTH MATCHED MEDIA STREAMING ACROSS A NETWORK BY DYNAMIC ENCODED MEDIA STREAM ADAPTATION

摘要

The main object of the present invention is to develop a method for adjusting the out-put bit-rate of the encoder (whose output stream is to be streamed onto a variable bandwidth network) to respond to network bandwidth changes without requiring making any changes or adjustments to the encoder parameters on the fly, thus allowing for a flexible rate control strategy with different supported bit-rates to closely track available network bandwidth and adjust according to its variation that can work with avariety of different compression standards (WMV, MPEG-4, MPEG-1 etc.) whether they support media stream scaling or not, hence we need not change the codec of the streaming system to one which supports scalability standard like SVC, AVC. The purpose of the present invention is to provide a flexible, low overhead method for achieving dynamic rate scaling in a media streaming system that can be used with a variety of different compression standards (for compressing the media stream before transmission).
