Abstract

To provide a content delivery system, a content delivery server, an information processing terminal, a content delivery program and a content delivery method with which content can be delivered appropriately while accommodating variations in resource conditions. A content server receives a delivery request from an information processing terminal and a resource condition of that terminal, modifies content corresponding to the delivery request in accordance with the resource condition, and delivers the content . The information processing terminal extracts the resource condition, transmits the resource condition and/or a content delivery request to the content server, receives the content delivered from the content server, and executes the content.

Claims

1. A content delivery system comprising a content server and an information processing terminal that are connected via a network, wherein the content server includes:

a receiving device receiving a delivery request from the information processing terminal and a resource condition of that terminal;

a modification device modifying content corresponding to the delivery request in accordance with the resource condition; and

a delivery device delivering the content,

and the information processing terminal includes;

an extraction device extracting the resource condition;

a transmitting device transmitting the resource condition and/or a content delivery request to the content server;

a receiving device receiving the content delivered from the content server; and

an execution device executing the content.

2. The information processing terminal according to claim 1, wherein The receiving device receives content to which the QoS control information is added, and the execution device executes the content based on the QoS control information.

3. The information processing terminal according to claim 1, Wherein the resource condition of the information processing terminal received by the receiving device is a resource condition which changes after initiation of the information processing terminal.

4. The information processing terminal according to claim 1, wherein the resource condition of the information processing terminal transmitted by the transmitting device includes at least a first resource condition of the information processing terminal just after the information processing terminal is activated and a second resource condition of the information processing terminal as other tasks are being processed by the information processing terminal.

5. The information processing terminal according to claim 3, wherein the receiving device receives content to which the QoS control information is added, and the execution device executes the content based on the QoS control information.

6. The information processing terminal according to claim 4, wherein the receiving device receives content to which QoS control information is added, and the execution device executes the content based on the QoS control information.

7. A content delivery method implemented by a content server and an information processing terminal that are connected via a network, the content server executing:

receiving a delivery request from an information processing terminal;

receiving a resource condition of the information processing terminal that dynamically changes during operation of the information processing terminal at predetermined intervals, at a predetermined timing, or when a change in resource conditions occurs;

modifying content corresponding to the delivery request in accordance with the resource condition; and

delivering the content; and

the information processing terminal executing;

extracting the resource condition;

transmitting the resource condition and/or a content delivery request to the content server;

receiving the content delivered from the content server; and

executing the content,

wherein the resource condition is changed by the operation of the information processing terminal.

8. A content delivery program according to claim 7, wherein the resource condition of the information processing terminal includes at least a first resource condition of the information processing terminal just after the information processing terminal is activated and a second resource condition of the information processing terminal as other tasks are being processed by the information processing terminal;

9. An information processing terminal comprising:

a receiving device receiving a delivery request from the information processing terminal and a resource condition of that terminal;

a modification device modifying content corresponding to the delivery request in accordance with the resource condition;

a delivery device delivering the content,

an extraction device extracting the resource condition that dynamically changes during operation of the information processing terminal, the extraction device extracting the resource condition at predetermined intervals, at a predetermined timing, or when a change in resource conditions occurs;

a transmitting device transmitting the resource condition and/or a content delivery request to the content server;

a receiving device receiving the content delivered from the content server; and

an execution device executing the content, wherein the resource condition is changed by the operation of the information processing terminal.

10. A content server, comprising:

a receiving device receiving a delivery request from the information processing terminal and a resource condition of that terminal;

a modification device modifying content corresponding to the delivery request in accordance with the resource condition; and

a delivery device delivering the content, wherein the information processing terminal includes;

an extraction device extracting the resource condition that dynamically changes during operation of the information processing terminal, the extraction device extracting the resource condition at predetermined intervals, at a predetermined timing, or when a change in resource conditions occurs;

a transmitting device transmitting the resource condition and/or a content delivery request to the content server;

a receiving device receiving the content delivered from the content server; and

an execution device executing the content, wherein the resource condition is changed by the operation of the information processing terminal.
