摘要

PROBLEM TO BE SOLVED: To provide a network system capable of further enhancing secrecy of a content streamed by a secret distribution method.;SOLUTION: When the content contained in a distribution system S comprising a plurality of node devices 2 connected to one another via a network is carried out streaming distribution the node device 2 in charge of distributing each of a plurality of partial streams STT 1 to STT 3 into which a stream to be distributed is divided is determined. For each of the node devices 2 determined, a piece of distribution schedule information SC is created including distribution handling time information indicating the partial streams STT 1 to STT 3 to be distributed by these node devices, distribution destination information indicating distribution destination node devices 2, and distribution source information indicating distribution source node devices 2. The pieces of distribution schedule information SC created are sent to the corresponding node devices 2 and distributed.;COPYRIGHT: (C)2008,JPO&INPIT
