Abstract

The present invention provides a mobile device that is able to receive content of a server even before a predetermined time interval elapses. The mobile device comprises a first transmission portion, which transmits a content transmission request to a first server, a second transmission portion, which transmits a content transmission request to a second server, a transmission control portion, which outputs transmission instruction information ordering the transmission of a content transmission request to the first transmission portion and second transmission portion, and a notice reception portion, which receives an urgent notice that is transmitted from the first server. The transmission control portion outputs transmission instruction information to the first transmission portion at a predetermined first time interval or when the notice reception portion receives the urgent notice, and outputs transmission instruction information to the second transmission portion at a second predetermined time interval.

Claims

1. A mobile device that receives and displays content transmitted from a first server and a second server respectively, comprising:

first transmitting means for transmitting a content transmission request requesting the transmission of the content to the first server;

second transmitting means for transmitting a content transmission request requesting the transmission of the content to the second server;

transmission control means for outputting transmission instruction information ordering the transmission of the content transmission request to the first transmitting means and the second transmitting means; and

notice receiving means for receiving an urgent notice ordering the acquisition of the content transmitted from the first server,

wherein the transmission control means outputs the transmission instruction information to the first transmitting means at a predetermined first time interval or when the notice receiving means receives the urgent notice, and outputs the transmission instruction information at a predetermined second time interval to the second transmitting means.

2. The mobile device according to claim 1, further comprising:

first time interval changing means for changing the first time interval.

3. The mobile device according to claim 1, further comprising:

second time interval changing means for changing the second time interval.

4. A content distribution system, comprising:

a first server that transmits first content and an urgent notice ordering the acquisition of the content;

a second server that transmits second content;

a mobile device for receiving and displaying the first content and the second content, which comprises first transmitting means for transmitting a content transmission request requesting the transmission of the first content to the first server, second transmitting means for transmitting a content transmission request requesting the transmission of the second content to the second server, transmission control means for outputting transmission instruction information that orders the transmission of the content transmission request to the first transmitting means and the second transmitting means, and receiving means for receiving the first content and the urgent notice transmitted from the first server and receiving the second content transmitted from the second server, and in which the transmission control means outputs the transmission instruction information to the first transmitting means at a predetermined first time interval or when the receiving means receives the urgent notice, and outputs the transmission instruction information at a predetermined second time interval to the second transmitting means, wherein

the first server transmits the first content to the receiving means of the mobile device upon receipt of the content transmission request transmitted from the first transmitting means of the mobile device; and

the second server transmits the second content to the receiving means of the mobile device upon receipt of the content transmission request transmitted from the second transmitting means of the mobile device.

5. The content distribution system according to claim 4, the first server further comprising:

first data receiving means for receiving first data and the urgent notice that are transmitted from a server constituting a first network;

first storing means for storing the first data; and

first extracting means for extracting, as the first content, at least a portion of the first data stored by the first storing means,

wherein the first server transmits the first content that is extracted by the first extracting means and the urgent notice to the receiving means of the mobile device, and

the second server comprising;

second data receiving means for receiving second data that are transmitted from a server constituting a second network;

second storing means for storing the second data; and

second extracting means for extracting, as the second content, at least a portion of the second data stored by the second storing means,

wherein the second server transmits the second content that is extracted by the second extracting means to the receiving means of the mobile device.

6. The content distribution system according to claim 5, wherein the mobile device further comprises first distributed content selecting means for selecting the first content that is extracted by the first extracting means of the first server;

the first server comprises first select content registering means for registering the first content selected by the first distributed content selecting means; and

the first extracting means extracts data registered by the first storing means in accordance with the first content registered by the first select content registering means.

7. The content distribution system according to claim 5 or 6, wherein the mobile device further comprises second distributed content selecting means for selecting the second content that is extracted by the second extracting means of the second server;

the second server comprises second select content registering means for registering the second content selected by the second distributed content selecting means; and

the second extracting means extracts data stored by the second storing means in accordance with the second content registered by the second select content registering means.

8. A content distribution method in a system that comprises a first server that transmits first content and an urgent notice ordering the acquisition of the content, a second server that transmits second content, and a mobile device that receives and displays the first content and the second content, comprising:

a first transmission step in which the first transmitting means of the mobile device transmits a content transmission request requesting. the transmission of the first content to the first server;

a second transmission step in which the second transmitting means of the mobile device transmits a content transmission request requesting the transmission of the second content to the second server;

a transmission control step in which transmission control means of the mobile device outputs transmission instruction information ordering the transmission of the content transmission request to the first transmitting means or the second transmitting means;

a first content transmission step in which the first server transmits the first content to the receiving means of the mobile device upon receipt of the content transmission request transmitted from the first transmitting means of the mobile device;

a second content transmission step in which the second server transmits the second content to the receiving means of the mobile device upon receipt of the content transmission request transmitted from the second transmitting means of the mobile device; and

a receiving step in which the receiving means of the mobile device receives the first content and the urgent notice that are transmitted from the first server or receives the second content that is transmitted from the second server,

wherein, in the transmission control step,

the transmission control means of the mobile device outputs the transmission instruction information to the first transmitting means at a predetermined first time interval or when the receiving means of the mobile device receives the urgent notice, and

the transmission control means of the mobile device outputs the transmission instruction information to the second transmitting means at a predetermined second time interval.
