Abstract
A system and method for streaming data over a communications network with varying streaming conditions, includes conditioning a data stream to create conditioned data representations including encoded representations targeting running conditions, wherein conditioning includes partitioning the data stream into data units, and generating the encoded representations of each of the data units, packaging the conditioned data representations with metadata specifying a target set of running conditions, wherein the conditioned data representations are packaged by pre-computing one or more trajectories among the encoded representations based on a given finite set of streaming conditions, observing a current run-time condition and selecting one of the packaged conditioned data representations for streaming over the computing network according to the running conditions in view of the current run-time condition in accordance with the observed current streaming condition, and a communications network responsive to the media server for streaming the selected packaged conditioned data representation.
