Abstract

A content reception device that receives a content having at least one reproduction start time predetermined, includes: a non-real time receiver for receiving a content in non-real time; a program information reference section for referring to program information which includes a reproduction start time of at least one content and a delivery method of said at least one content; a scheduler for scheduling reception of a content whose delivery method is non-real time delivery by the non-real time receiver based on a current time and a reproduction start time of the content; and a content storage section for storing at least one content received by the non-real time receiver.

Claims

1. A device for receiving a content having at least one reproduction start time predetermined, comprising:

a non-real time receiver for receiving a content in non-real time;

a program information reference section for referring to program information which includes a reproduction start time of at least one content and a delivery method of said at least one content;

a scheduler for scheduling reception of a content whose delivery method is non-real time delivery by the non-real time receiver based on a current time and a reproduction start time of the content; and

a content storage section for storing at least one content received by the non-real time receiver.

2. The device according to claim 1, wherein the scheduler schedules the reception of the content to start before the reproduction start time so that the non-real time delivery of the content will have been completed before the reproduction start time.

3. The device according to claim 2, further comprising:

a time estimator for estimating a time required for non-real time delivery of the content,

wherein the scheduler schedules the reception of the content to start based on an estimated time, the reproduction start time and the current time.

4. The device according to claim 3, wherein the scheduler schedules the reception of the content to start the estimated time or more before the reproduction start time.

5. An electronic equipment system comprising the device according to claim 1, further comprising:

an information input/output section which allows a user operation of selecting a desired content from the program information;

a data transfer interface for connecting the device to a network; and

an output section for outputting the content to reproduce it on a reproduction device.

6. A content delivery system for delivering a content having at least one reproduction start time predetermined to the device according to claim 1, comprising:

a program information delivery section for delivering the program information to the device;

a real time delivery providing section for delivering a content for real time delivery to the device; and

a non-real time delivery providing section for delivering a content for non-real time delivery to the device.

7. The content delivery system according to claim 6, wherein the program information further includes a data size of a content for non-real time delivery.

8. A method for receiving a content having at least one reproduction start time predetermined, comprising:

referring to program information through a program information reference section, wherein the program information includes a reproduction start time of at least one content and a delivery method of said at least one content;

scheduling reception of a content whose delivery method is non-real time delivery based on a current time and a reproduction start time of the content; and

storing at least one content received by the non-real time delivery in a content storage section.

9. The method according to claim 8, wherein the reception of the content is scheduled to start before the reproduction start time so that the non-real time delivery of the content will have been completed before the reproduction start time.

10. The method according to claim 9, further comprising:

a time estimator for estimating a time required for non-real time delivery of the content,

wherein the reception of the content is scheduled to start based on an estimated time, the reproduction start time and the current time.

11. The method according to claim 10, wherein the reception of the content is scheduled to start the estimated time or more before the reproduction start time.

12. A recording medium recording a computer program which instructs a computer to function as a device for receiving a content having at least one reproduction start time predetermined, comprising:

referring to program information through a program information reference section, wherein the program information includes a reproduction start time of at least one content and a delivery method of said at least one content;

scheduling reception of a content whose delivery method is non-real time delivery based on a current time and a reproduction start time of the content; and

storing at least one content received by the non-real time delivery in a content storage section.
