Terminal apparatus used in information distribution system, recording medium on which information processing program is recorded, and information processing method

A terminal apparatus in an information distribution system which, being formed by a participation of a plurality of terminal apparatus mutually connected via a network, carries out a transmission and reception of contents information among the terminal apparatus, the terminal apparatus comprising:

• a contents information storage section which stores the contents information;
• a contents list storage section which stores a list of the contents information stored in the contents information storage section;
• and
• a controller which controls the contents information storage section and the contents list storage section, the controller including:
• a stop control section which puts the contents information storage section into a stopped condition;
• a contents existence determination section which, in a case of receiving a request for a distribution of contents information from another terminal apparatus, by means of a contents list stored in the contents list storage section, determines whether or not the contents information which is the subject of the distribution request is stored in the contents information storage section;
• a drive control section which, in a case in which it is determined, by the contents existence determination section, that the contents information which is the subject of the distribution request is stored in the contents information storage section, puts the contents information storage section into a driven condition;
• and
• a contents distribution section which, after the contents information storage section has attained the driven condition due to the drive control section, retrieves the contents information which is the subject of the distribution request from the contents information storage section, and distributes it.
