Data processing device, method thereof, program thereof, and recording medium recording the program

摘要

A processing section (250) of a recording/reproducing device (200) acquires content data of a content set by a user, and acquires program-linked data which links with content-main-data, from the content data. The processing section (250) acquires set keyword data stored in a memory (240), and determines whether or not the program-linked data includes a BML file having a character string related to a keyword set by the user. If it is determined that a BML file having the related character string is included, the processing section (250) specifies and acquires content-main-data with which the BML file links, from the content-main-data acquired.
