Abstract
A data recording device is provided to record and redistribute stream data such as TV programs without imposing loads proportional to the number of users. Stream data of a distributed program is collated by a recording range judging sectionwith data already recorded of a stream data recording sectionand, based on results from the collation, only newly distributed data is appended to the stream data recording section. Recording demand information representing a range of stream data of a program that a user makes a request for recording is recorded in a range recording sectionand a user identifier to identify the user is recorded in a manner to be associated with the above recording demand range information. Stream data only in a range corresponding to the above recording demand range information of the user recorded by the above demand range recording processing is read out by a redistributing sectionfrom the stream data recording sectionand is redistributed to the user.
