Abstract

A system including a delivery server and a user terminal is disclosed. The deliver server includes a processor configured to transmit metadata including schedule information about release dates for content items, receive a request for one of the content items, the request being based on the schedule information included in the metadata, and transmit the requested content item in response to the request. The user terminal includes a processor configured to receive the metadata including the schedule information about release dates for the content items, send the request for one of the content items based on the schedule information included in the metadata, and receive the requested content item.

Claims

1. A system comprising:

a delivery server comprising a processor; and

a user terminal comprising a processor,

wherein the delivery server processor is configured to;

transmit metadata including schedule information about release dates for content items;

receive a request for one of the content items, the request being based on the schedule information included in the metadata; and

transmit the requested content item in response to the request, and

wherein the user terminal processor is configured to;

receive the metadata including the schedule information about release dates for the content items;

send the request for one of the content items based on the schedule information included in the metadata; and

receive the requested content item.

2. A delivery server comprising a processor configured to:

transmit metadata including schedule information about release dates for content items;

receive a request for one of the content items, the request being based on the schedule information included in the metadata; and

transmit the requested content item in response to the request.

3. The delivery server according to claim 2, wherein at least one of a title, an individual, a genre, a time, or a place is common to the content items.

4. The delivery server according to claim 2, further comprising a database configured to store the content items;

wherein the content items stored in the database are replaced based on the release dates of the content items.

5. The delivery server according to claim 2, wherein the metadata includes at least one of a main title of a series, a number of content items in the series, and a subtitle for the content items in the series.

6. The delivery server according to claim 2, wherein the metadata further includes an expiration date for the content items.

7. The delivery server according to claim 2, wherein the metadata is updated to reflect new release dates for the content items.

8. The delivery server according to claim 5, wherein updated metadata is transmitted in response to a request made by a user terminal for transmission of the updated metadata.

10. The user terminal according to claim 7, wherein at least one of a title, an individual, a genre, a time, or a place is common to the content items.

11. The user terminal according to claim 7, further comprising a display for displaying the schedule information included in the metadata.

14. The user terminal according to claim 7, wherein the metadata is updated to reflect new release dates for the content items.

15. The user terminal according to claim 10, further comprising a storage device to store the received metadata;

wherein the processor is further configured to;

verify whether the metadata has been updated by the delivery server by comparing metadata stored in the delivery server with the metadata stored in the storage device; and

request transmission of the updated metadata if the metadata has been updated;

wherein the storage device stores the updated metadata.

9. A user terminal comprising a processor configured to:

receive metadata including schedule information about release dates for content items;

send a request for one of the content items based on the schedule information included in the metadata; and

receive the requested content item.

12. The user terminal according to claim 9, wherein the metadata includes at least one of a main title of a series, a number of content items in the series;

and a subtitle for the content items in the series.

13. The reception apparatus according to claim 9, wherein the metadata further includes an expiration date for the content items.

16. A computer-readable medium containing processor readable instructions for causing a computer to execute a method, the method comprising:

transmitting metadata including schedule information about release dates for content items;

receiving a request for one of the content items, the request being based on the schedule information included in the metadata; and

transmitting the requested content item in response to the request.

17. A computer-readable medium containing processor readable instructions for causing a computer to execute a method, the method comprising:

receiving metadata including schedule information about release dates for content items;

sending a request for one of the content items based on the schedule information included in the metadata; and

receiving the requested content item.

18. A computer-implemented method comprising:

transmitting metadata including schedule information about release dates for content items;

receiving a request for one of the content items, the request being based on the schedule information included in the metadata; and

transmitting the requested content item in response to the request.

19. A computer-implemented method comprising:

receiving metadata including schedule information about release dates for content items;

sending a request for one of the content items based on the schedule information included in the metadata; and

receiving the requested content item.
