Abstract

A system includes a server and at least a client. The sever transfers a code data to the client. The client receives the code data from the server and decodes the code data. The client includes a requesting unit configured to request a code data stored in the server, a first receiving unit configured to receive the code data from the server, a decoding unit configured to decode the code data which is received from the server and a display unit configured to display an image data which is generated by the decoding unit. In addition, the server includes a second receiving unit configured to receive the request from a client, a selecting unit configured to select the code data which is requested from the client, a transferring unit configured to transfer the code data which is selected by the selecting unit, wherein the code data is a part of at least code data of JPM file.

Claims

1. A system comprising:

a client including

a requesting unit configured to request a code data stored in the server,

a first receiving unit configured to receive the code data from the server,

a decoding unit configured to decode the code data which is received from the server, and

a display unit configured to display an image data which is generated by the decoding unit; and

a server including

a second receiving unit configured to receive the request from a client,

a selecting unit configured to select the code data which is requested from the client, and

a transferring unit configured to transfer the code data which is selected by the selecting unit,

wherein the code data is a part of at least code data of JPM file, and

an order of transferring objects in the code data is set based on a priority order.

2. The system as claimed in claim 1,

wherein the server is configured to transfer a remaining object of the code data that is requested from the client after transferring an object that includes the code data which is requested from the client.

3. The system as claimed in claim 1,

wherein the server is configured to transfer all objects that include the code data which is requested from the client sequentially, and

the client is configured to decode the code data which is received from the server and to display an image data which is generated by decoding.

4. The system as claimed in claim 1,

wherein the client is configured to transfer an interrupt signal to the server, and

the server is configured to stop transferring the object when the server receives the interrupt signal from the client.

5. The system as claimed in claim 1, further comprising:

a calculating unit configured to calculate a proportion of characteristic area and picture area in an image data,

wherein the priority order of the object is set based on the proportion.

6. A method comprising:

requesting a code data stored in a server;

receiving the request from a client;

receiving the code data from the server;

a selecting the code data which is requested from the client; and

transferring the code data which is selected by the selecting, wherein an order of transferring objects in the code data is set based on a priority order;

decoding the code data which is received from the server; and

displaying an image data which is generated by the decoding,

wherein the code data is a part of at least code data of JPM file.

7. The method as claimed in claim 6, further comprising:

transferring a remaining object of the code data that is requested from the client after transferring an object that composes a code data which is requested from the client.

8. The method as claimed in claim 6, further comprising:

transferring all objects that include a code data which is requested from the client sequentially;

decoding the code data which is received from the server; and

displaying an image data which is generated by decoding.

9. The method as claimed in claim 6, further comprising:

transferring an interrupt signal to the server; and

stopping a transferring of the object when the server receives the interrupt signal from the client.

10. The method as claimed in claim 9, further comprising:

calculating a proportion of characteristic area and picture area in an image data; and

setting the priority order of the object based on the proportion.

11. A computer readable storage medium, encoded with instructions, which when executed by a processing device causes the processing device to implement a method comprising:

requesting a code data stored in a server;

receiving the request from a client;

receiving the code data from the server;

a selecting the code data which is requested from the client; and

transferring the code data which is selected by the selecting, wherein an order of transferring objects in the code data is set based on a priority order;

decoding the code data which is received from the server; and

displaying an image data which is generated by the decoding,

wherein the code data is a part of at least code data of JPM file.
