Abstract

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.

receives identification information for identifying said specified decoding method applied to the content obtaining apparatus, and specifying information representing specified content data, transmitted from said content obtaining apparatus,
in response to receiving the identification information, detects whether or not specified compressed content data generated by compressively coding said specified content data by said specified compression coding method corresponding to said identification information has been stored thereon according to said identification information and said specifying information, to generate a detection result,
in response to determining that the detection result indicates that said specified compressed content has been stored, reads said specified compressed content data or in response to determining that the detection result indicates that said specified compressed content data has not been stored, compressively codes said specified content data to generate said specified compressed content data, said specified content data being original data of the specified compressed content data before being compressively codes by said specified compression coding method, and
transmits said specified compressed content data to said content obtaining apparatus;
and
said content obtaining apparatus:
transmits said identification information and said specifying information to said content providing apparatus,
receives said specified compressed content data transmitted from said content providing apparatus, and
decodes said specified compressed content data by said specified decoding method, and generating said specified content data.
