摘要： A system for selecting one of a plurality of video versions in response to a video request by a user of a user device having a processor is disclosed. The system includes a stream selector configured to adaptively select optimized bit-rates by selecting one of the plurality of video versions to deliver to the user device. The stream selector i) estimates an expected future utility of the user at different times during a billing cycle based on a remaining data quota and ii) selects one of the plurality of video versions that maximizes a current utility plus expected future utility of the user at selection time. A user profiler may be configured to perform predictive analysis of user data usage by determining the likelihood of a user requesting a video during each time interval of the user's billing cycle and a video type including utility vector and cost vector information. A video profiler may be configured to generate a plurality of utility vectors and cost vectors, each version of a video having a different bit-rate and an associated utility vector and cost vector.
