Abstract

A content delivery apparatus includes an external input portion, a content reception portion and a delivery portion. To the external input portion, first content having at least a fundamental component is inputted. The content reception portion receives second content having a fundamental component and an extended component. When delivering the first content, the delivery portion delivers the fundamental component of the first content to a client apparatus more than once.

Claims

1. A content delivery apparatus comprising:

an external input portion to which first content having at least a fundamental component is inputted;

a content reception portion that receives second content having the fundamental component and an extended component; and

a delivery portion that delivers the fundamental component of the first content to a client apparatus more than once when delivering the first content.

2. The content delivery apparatus according to claim 1 further comprising a buffer that temporarily holds the second content, wherein

the content delivery portion delivers the fundamental component and the extended component of the second content after temporarily holding thereof in the buffer when delivering the second content.

3. The content delivery apparatus according to claim 2 comprising:

a first buffer is the buffer;

a second buffer that temporarily holds the second content, the second buffer being a separate buffer different from the first buffer; and

a reproduction portion that reproduces the second content that is held in the second buffer.

4. The content delivery apparatus according to claim 1, wherein

the delivery portion delivers the fundamental component of the first content without confirming a status of connection to the client apparatus when delivering the first content.

5. The content delivery apparatus according to claim 1, wherein

the delivery portion does not deliver the extended component of the first content when delivering the first content.

6. The content delivery apparatus according to claim 1, wherein

the delivery portion delivers the fundamental component of the first content without delivering the extended component thereof when delivering the first content if number of the client apparatus as delivery destinations is equal or more than a predetermined number.

7. The content delivery apparatus according to claim 1, wherein

the fundamental component consists of data that have undergone irreversible compression;

and

the extended component consists of data to correct the fundamental component.

8. The content delivery apparatus according to claim 1, wherein

the fundamental component is transmitted through connectionless communication.

9. A content delivery system comprising:

the content delivery apparatus according to claim 1; and

a client apparatus that receives the first content and the second content from the content delivery apparatus.

10. A content delivery method comprising:

inputting first content having at least a fundamental component, or receiving second content having a fundamental component and an extended component; and

delivering the fundamental component of the first content to a client apparatus more than once when delivering the first content.

11. The content delivery method according to claim 10, the method including:

temporarily holding the second content in a buffer; and

delivering the fundamental component and the extended component of the second content after temporarily holding thereof in the buffer when delivering the second content.

12. The content delivery method according to claim 11, the method including:

temporarily holding the second content in a first buffer;

temporarily holding the second content in a second buffer that is a separate buffer different from the first buffer; and

reproducing the second content that is held in the second buffer.

13. The content delivery method according to claim 10, the method including:

delivering the fundamental component of the first content without confirming a status of connection to the client apparatus when delivering the first content.

14. The content delivery method according to claim 10, the method including:

not delivering the extended component of the first content when delivering the first content.

15. The content delivery method according to claim 10, the method including:

delivering the first content and the fundamental component of the first content without delivering the extended component of the first content when delivering the first content if number of the client apparatus as delivery destinations is equal or more than a predetermined number.

16. The content delivery method according to claim 10, the method including:

using the fundamental component consisting of data that have undergone irreversible compression, and

the extended component consisting of data to correct the fundamental component.

17. The content delivery method according to claim 10, the method including:

transmitting the fundamental component through connectionless communication.
