In a data providing server 1101, whether or not specified compressed content data D51 generated by means of a specified compression coding method corresponding to terminal identification information has been stored in a content database 1113 is detected, according to content specifying data D53 transmitted from a portable dedicated terminal 1104. If the specified compressed content data D51 has been stored, the data providing server 1101 reads and transmits this to the portable dedicated terminal 1104. And if the specified compressed content data D51 has not been stored, the data providing server 1101 generates the specified compressed content data D51 by means of the specified compression coding method, and transmits this to the portable dedicated terminal 1104. Thereby, the specified compressed content data D51 generated by means of a specified decoding method can be properly provided to the portable dedicated terminal 1104, and the user can easily view a content based on the content data. |
