Abstract

To provide a terminal apparatus, an information processing program, and an information processing method, with which a noise reduction and power saving are possible. A terminal apparatus puts an HDD into a stopped condition when a main switch is in a deactivated condition and, receiving a distribution request, temporarily puts the HDD into a driven condition when contents information which is a subject of the distribution request is stored in the HDD, and distributes the contents information. When the distribution of the contents information is completed, the terminal apparatus puts the HDD into the stopped condition. By this means, holding a time of the driven condition of the HDD to a minimum, a noise reduction and power saving are realized.

Claims

1. 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.

2. The terminal apparatus according to claim 1, wherein

the stop control section of the controller, in a case of receiving an instruction for the contents information storage section to shift from the driven condition to the stopped condition, when distributing the contents information, puts the contents information storage section into the stopped condition after the distribution of the contents information is completed.

3. The terminal apparatus according to claim 1, wherein the controller further includes:

a contents list update section which, after a reception of contents information from another terminal apparatus and its storage in the contents information storage section is completed, updates the list stored in the contents list storage section.

4. The terminal apparatus according to claim 1, further comprising:

a contents leading portion storage section which stores a predetermined size of leading portion among the contents information, wherein

the contents distribution section of the controller retrieves the leading portion of the contents information which is the subject of the distribution request from the contents leading portion storage section, distributes it and, after the contents information storage section attains the driven condition, and the distribution of the leading portion is completed, retrieves the contents information which is the subject of the distribution request from the contents information storage section, and continues distributing.

5. The terminal apparatus according to claim 4, wherein the controller further includes:

a contents storage control section which, in a case of receiving contents information from another terminal apparatus, stores the predetermined size of leading portion among the contents information in the contents leading portion storage section, and stores contents information succeeding the leading portion in the contents information storage section.

6. The terminal apparatus according to claim 4, wherein

the drive control section of the controller, in a case of receiving a distribution request from another terminal apparatus, puts the contents information storage section into the driven condition after a predetermined time elapses, and

the contents distribution section of the controller retrieves the leading portion of the contents information which is the subject of the distribution request from the contents leading portion storage section, distributes it and, after the contents information storage section attains the driven condition, and the distribution of the leading portion is completed, retrieves the contents information which is the subject of the distribution request from the contents information storage section, and continues distributing.

7. The terminal apparatus according to claim 1, further comprising:

a contents leading portion storage section which stores a predetermined size of leading portion among the contents information, wherein

the drive control section of the controller, in a case of receiving contents information from another terminal apparatus, puts the contents information storage section into the driven condition after a predetermined time elapses, and the controller further includes;

a contents storage control section which, in a case of receiving a distribution of contents information, stores the predetermined size of leading portion among the contents information in the contents leading portion storage section and, after the contents information storage section attains the driven condition, and the storage of the leading portion is completed, stores contents information succeeding the leading portion in the contents information storage section.

8. A recording medium on which an information processing program, which causes a computer to function as each section of the terminal apparatus according to claim 1, is recorded so as to be readable by the computer.

9. An information processing method 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 including a contents information storage section which stores the contents information, and a contents list storage section which stores a list of the contents information stored in the contents information storage section, the method comprising the steps of:

putting the contents information storage section into a stopped condition;

determining, 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, whether or not the contents information which is the subject of the distribution request is stored in the contents information storage section;

putting the contents information storage section into a driven condition in a case in which it is determined that the contents information which is the subject of the distribution request is stored in the contents information storage section; and

after the contents information storage section has attained the driven condition, retrieving the contents information which is the subject of the distribution request from the contents information storage section, and distributing it.
