At step S1, a URI of a desired content is input. At step S3, corresponding to the input URI, a proper resolution executing portion is selected. A plurality of resolution executing portions perform processes in parallel. At step S4, with reference to a correlation table that correlates identification names of contents and file names in a storing unit, a name resolving process is performed. At step S6, with reference to name resolution table data transmitted as an MPEG2 section table in a satellite broadcast, a name resolving process is performed. At step S8, by communicating with a name resolving service on a network such as DNS, a name resolving process is performed. After the name resolving processes in all methods have been completed, at step S10, an acquired location list L is sent to a content acquiring portion. The content acquiring portion references the list L and acquires a content designated by the URI.
