Abstract

A server computer sets a priority order of each of contents based on an attribute of each of the contents designated by HTML data and provides the HTML data including the priority order with a client computer. The client computer acquires the contents from the server computer by using streams with priorities depending on the priority order of each of the contents designated by the HTML data provided from the server computer. The client computer controls display using a part of the contents and caches other contents from among the acquired contents.

4. The information processing system according to claim 1, wherein the setting unit sets the priority order of the contents based on an attribute of the contents designated by the data and environment information about the information processing device.

5. The information processing system according to claim 4, wherein environment information about the information processing device includes at least any one of an upload/download bandwidth and a round trip time between the information processing device and the server.

6. The information processing system according to claim 5, wherein the setting unit determines whether a communication environment between the information processing device and the server is either a high-speed communication environment or a low-speed communication environment based on the round trip time between the information processing device and the server, and the setting unit reduces the number of contents of which the priority order is set low when the communication environment is a low-speed communication environment than the number of contents of which the priority order is set low when the communication environment is a high-speed communication environment.

7. The information processing system according to claim 4, wherein the number of the streams which are capable of being simultaneously used by the acquirer is limited by environment information about the information processing device.

8. A control method in an information processing system comprising a server that provides data described in a markup language and an information processing device that performs display control in accordance with the provided data, the control method comprising:

a setting step, performed by the server, of setting a priority order of each of contents based on an attribute of each of the contents designated by the data;

a providing step, performed by the server, of providing the data including the set priority order to the information processing device;

an acquiring step, performed by the information processing device, of acquiring contents from the server by using streams with priorities depending on the priority order of each of the contents designated by the data;

a controlling step, performed by the information processing device, of controlling display using a part of the contents from among the acquired contents; and

a caching step, performed by the information processing device, of caching other contents from among the acquired contents.

9. A server that provides data described in a markup language to an information processing device which performs display control in accordance with the provided data, the server comprising:

setting unit for setting a priority order of each of contents based on an attribute of each of the contents designated by the data;

providing unit for providing the data including the set priority order to the information processing device; and

distributing unit for receiving a request for acquiring the contents from the information processing device that makes a request for acquiring the contents by using streams with priorities depending on the priority order of each of the contents designated by the data and distributing the contents to the information processing device,

wherein the information processing device controls display using a part of the contents and caches other contents from among the distributed contents.

10. The server according to claim 9, wherein an attribute of the contents is at least any one of a size, type, and content of the contents.

11. The server according to claim 9, wherein the setting unit sets a first priority order to a content of which the size is equal to or greater than a threshold value and sets a second priority order higher than the first priority order to a content of which the size is less than the threshold value from among the contents designated by the data.

12. The server according to claim 9, wherein the setting unit sets the priority order of the contents based on an attribute of the contents designated by the data and environment information about the information processing device.

13. The server according to claim 12, wherein environment information about the information processing device includes at least any one of an upload/download bandwidth and a round trip time between the information processing device and the server.

14. The server according to claim 13, wherein the setting unit determines whether a communication environment between the information processing device and the server is either a high-speed communication environment or a low-speed communication environment based on the round trip time between the information processing device and the server, and the setting unit reduces the number of contents of which the priority order is set low when the communication environment is a low-speed communication environment than the number of contents of which the priority order is set low when the communication environment is a high-speed communication environment.

15. The server according to claim 12, wherein the number of the streams which are capable of being simultaneously used by the information processing device is limited by environment information about the information processing device.

17. A non-transitory storage medium on which is stored a computer program for making a computer function as the server according to claim 9.
