Information search method, information search server, and information search system for providing content based on current progress status of content

摘要

In an information search server 600, a database includes a table storing a progress status of content, and information related to the content at the progress status, and a table storing user information with respect to a content playback apparatus, an identifier of the content playback apparatus, and an identifier of a terminal apparatus that differs from the content playback apparatus. A connecting user management unit manages user information with respect to the content playback apparatus connected to the information search server. A related information acquisition unit acquires a current progress status of content being played back on the content playback apparatus, and acquires information related to the content at the current progress status. A connecting user management unit identifies a terminal apparatus that differs from the content playback apparatus, and the related information acquisition unit transmits the related information to the terminal apparatus.
