Abstract
A method of efficiently transmitting streamed data of a program to multiple clients requesting the program at different times ranks the requests in a multilevel hierarchy, which describes merging of data streams servicing the requests. The multilevel hierarchy changes dynamically as new requests arrive or existing data streams are merged to reduce the bandwidth or other costs required to serve the requests. The hierarchy may be established by simple rules or by a modeling of the actual cost of possible hierarchies.
