Abstract

A server stores a media content and an execution program for processing the media content, and determines a usage rule for the media content to be transmitted to a terminal. The server distributes the usage rule, the media content, and the execution program to the terminal. The terminal stores the distributed usage rule, media content, and execution program. The terminal executes the stored execution program and processes the stored media content within the bounds of the usage rule as stored. The server may perform a billing process in accordance with the determined usage rule, or select and distribute a media content or an execution program in accordance with the processing ability of the terminal or a state of communications. Moreover, the server may distribute, in addition to the execution program, middleware for constructing an operating environment for the execution program.

Claims

1. A contents distribution system for distributing a content via a communication network, said contents distribution system comprising:

a server; and

a terminal,

wherein said server comprises;

a condition setting unit operable to determine a usage rule for the content to be transmitted to said terminal;

a server-side storage unit operable to store an execution program for processing at least the content; and

a transmission unit operable to transmit the content, the execution program, and the usage rule to said terminal,

wherein said terminal comprises;

a reception unit operable to receive the content, the execution program, and the usage rule from said server;

a terminal-side storage unit operable to store the content, the execution program, and the usage rule which are received by said reception unit;

a control unit operable to, at a time of using the content, permit use of the content within bounds of the usage rule; and

a processing unit operable to execute the execution program stored in said terminal-side storage unit to process the content stored in said terminal-side storage unit, and

wherein the execution program checks with said control unit whether or not use of the content received by said reception unit is permitted, and processes the content only when use of the content is permitted.

2. A terminal comprising:

a reception unit operable to receive a content, an execution program, and a usage rule for the content, from a server, via a communication network;

a storage unit operable to store the content, the execution program, and the usage rule which are received by said reception unit;

a control unit operable to, at a time of using the content, permit use of the content within bounds of the usage rule; and

a processing unit operable to execute the execution program stored in said storage unit to process the content stored in said storage unit,

wherein the execution program checks with said control unit whether or not use of the content received by said reception unit is permitted, and processes the content only when use of the content is permitted.

3. A contents distribution system for distributing a content via a communication network, said contents distribution system comprising:

a server; and

a terminal,

wherein said server comprises;

a condition setting unit operable to determine a usage rule for the content to be transmitted to said terminal;

a server-side storage unit operable to store the content, an execution program for processing the content, and the usage rule for the content; and

a transmission unit operable to transmit, to said terminal, the content, the execution program, and the usage rule which are stored in said server-side storage unit,

wherein said terminal comprises;

a reception unit operable to receive the content, the execution program, and the usage rule from said server;

a terminal-side storage unit operable to store the content, the execution program, and the usage rule which are received by said reception unit;

a control unit operable to, at a time of using the content, permit use of the content within bounds of the usage rule; and

a processing unit operable to execute the execution program stored in said terminal-side storage unit to process the content stored in said terminal-side storage unit, and

wherein the execution program checks with said control unit whether or not use of the content received by said reception unit is permitted, and processes the content only when use of the content is permitted.

4. A terminal comprising:

a reception unit operable to receive a content, an execution program, and a usage rule for the content, from a server, via a communication network;

a storage unit operable to store the content, the execution program, and the usage rule which are received by said reception unit;

a control unit operable to, at a time of using the content, permit use of the content within bounds of the usage rule; and

a processing unit operable to execute the execution program stored in said storage unit to process the content stored in said storage unit,

wherein the execution program checks with said control unit whether or not use of the content received by said reception unit is permitted, and processes the content only when use of the content is permitted.
