Abstract:
1. A data streaming method comprising: establishing a plurality of data paths extending to a first receiver respectively from a plurality of data, supply sources, each of said data supply sources being capable of supplying the same stream data to the first receiver, wherein the data supply sources include another receiver, and wherein establishing the plurality of data paths includes establishing a data path between the another receiver and the first receiver when a difference between a position in said stream data that is being reproduced by said another receiver and a position in said stream data that is being reproduced in said first receiver is equal to or smaller than a predetermined value; and performing rate-distortion optimization of said plurality of data paths to provide said stream data to said first receiver, wherein mutually asynchronous clocks are set for said respective data paths to attain said rate-distortion optimization, said plurality of data supply sources further eludes a first server which stores said stream data, and establishing said plurality of data paths comprises accessing the first server which stores said stream data and simultaneously querying said another receiver as to whether said another receiver has said stream data.
