Abstract

A method of controlling reproduction in a broadcast recording device, is discussed. According to an embodiment, the method includes when there is a request for reproduction of a title, determining if an outputting of advertisement associated with the title is required for the reproduction of the title; selectively outputting the advertisement based on the determination result; and reproducing the title, after the outputting of the advertisement has been completed.

Claims

1. A method of controlling reproduction in a broadcast recording device, comprising:

when there is a request for reproduction of a title, determining if an outputting of advertisement associated with the title is required for the reproduction of the title;

selectively outputting the advertisement based on the determination result; and

reproducing the title, after the outputting of the advertisement has been completed.

2. The method as set forth in claim 1, wherein the determining step includes:

checking the title to detect a presence of CM (commercial message) flag information; and

examining CM viewing information of the CM flag information if the CM flag information is present in the title.

3. The method as set forth in claim 2, wherein the determining step determines that the outputting of the advertisement is required for the reproduction of the title, if the CM viewing information indicates that the number of the outputtings of the advertisement is less than a preset number.

4. The method as set forth in claim 2, wherein the determining step determines that the outputting of the advertisement is not required for the reproduction of the title, (a) if the CM flag information is not present in the title or (b) if the CM viewing information indicates that the number of the outputtings of the advertisement is equal to or great than a preset number.

5. The method as set forth in claim 1, wherein at least one of data of the advertisement and viewing information of the advertisement is recorded on a medium along with the title, and the determining step is performed using the viewing information.

6. The method as set forth in claim 1, wherein the determining step is performed using viewing information of the advertisement, and data of the advertisement is transmitted from an external server related to the title.

7. The method as set forth in claim 6, wherein the viewing information includes link information for connecting to the external server.

8. The method as set forth in claim 6, wherein the external server controls a transmission speed of the advertisement data.

9. The method as set forth in claim 6, wherein the advertisement data transmitted from the external server is an advertisement that is pre-designated for the title or is updated in real time by the external server.

10. The method as set forth in claim 6, wherein the external server provides a menu screen for allowing a user to select a desired type of advertisement.

11. The method as set forth in claim 10, wherein a number of advertisements and/or a duration of each advertisement to be viewed is determined differently according to the selected type of advertisement.

12. The method as set forth in claim 10, wherein an additional service related to the title is provided according to at least one of the following:

the selected type of advertisement, a time period of viewing of advertisement or advertisements, or a number of repeated viewings of an identical advertisement.

13. The method as set forth in claim 1, wherein the determining step examines the number of viewings of the advertisement, and the outputting step outputs the advertisement if the number of viewings of the advertisement is less than a predetermined number and updates the number of viewings of the advertisement after the outputting of the advertisement has been completed.

14. The method as set forth in claim 1, wherein a user'"'"'s command related to trick play is disregarded while the advertisement is output.

15. The method as set forth in claim 1, wherein the title is recorded on a medium in an encrypted state, and is decrypted and reproduced using an encryption key generated when the reproduction of the advertisement is completed.

16. The method as set forth in claim 15, wherein the encryption key is distributed through data of the advertisement.

17. The method as set forth in claim 1, wherein the title is encrypted and recorded using different encryption keys for respective sections of the title, and the encryption keys for the respective sections are separately stored in multiple pieces of data of the advertisement.

18. A broadcast device comprising:

a broadcast receiver configured to select a broadcast channel and to receive broadcast signals;

a recording unit configured to record the broadcast signals on a medium;

a signal processor configured to decode the broadcast signals from the broadcast receiver or the broadcast signals read from the medium, and to output audio/video signals; and

a controller configured to control the recording unit and the signal processor,

wherein if there is a request for reproduction of a title, the controller determines if an outputting of advertisement associated with the title is required for the reproduction of the title, selectively outputs the advertisement based on the determination result, and reproduces the title after the outputting of the advertisement has been completed.

19. The broadcast device as set forth in claim 18, wherein the controller checks the title to detect a presence of CM (commercial message) flag information, and examines CM viewing information of the CM flag information if the CM flag information is present in the title.

20. The broadcast device as set forth in claim 19, wherein the controller determines that the outputting of the advertisement is required for the reproduction of the title, if the CM viewing information indicates that the number of the outputtings of the advertisement is less than a preset number.

21. The broadcast device as set forth in claim 19, wherein the controller determines that the outputting of the advertisement is not required for the reproduction of the title, (a) if the CM flag information is not present in the title or (b) if the CM viewing information indicates that the number of the outputtings of the advertisement is equal to or great than a preset number.

22. The broadcast device as set forth in claim 18, further comprising:

a communication unit configured to receiving data of the advertisement from an external server,

wherein the controller controls the communication unit so as to be connected to the external server for exchanging data according to link information included in viewing information related to a viewing of the advertisement, and

wherein the controller determines if the outputting of advertisement is required for the reproduction of the title by using the viewing information.

23. The broadcast device as set forth in claim 18, wherein the controller disregards a user'"'"'s command related to trick play while the advertisement is output.

24. The broadcast device as set forth in claim 18, wherein an encryption key, which is used to decrypt and reproduce the title, is stored with viewing information of the advertisement or is distributed through data of the advertisement.

25. The broadcast device as set forth in claim 18, wherein the controller examines the number of viewings of the advertisement, outputs the advertisement if the number of viewings of the advertisement is less than a predetermined number, and updates the number of viewings of the advertisement after the outputting of the advertisement has been completed.
