Optimized client side rate control and indexed file layout for streaming media

摘要: An indexed file layout, comprising index information, is defined for segmented streaming of multimedia content. The information can comprise program description and segment information. In addition, the layout files containing segments program, where are each encoded at one or more bitrates independently other program. supports client switching between different boundaries. Optimized client-side rate control content be provided by defining a plurality states, selecting available paths based on constraint conditions, best path through states (e.g., distortion measure). solution correspond to specific bitrate segment, in another measure buffer fullness.
