Abstract

A system and method that extract advertising materials from a video source, describes and stores the extracted materials in a structured database for various applications.

The system for extracting, advertising or other promotional segments from a video signal may comprise means to convert, if necessary, the video signal to a digital format, means for storing said video signal in a database, means for scanning said video signal for the presence of predetermined characteristics and means to associate such characteristics with the start and end of each such segment.

Claims

1. A system for extracting advertising or other promotional segments from a video signal comprising:

a. means to convert, if necessary, the video signal to a digital format,

b. means for storing said video signal in a database,

c. means for scanning said video signal for the presence of predetermined characteristics,

d. means to associate said characteristics with the start and the end of each such segments.

2. A system as described in claim 1, further comprising means for storing said video signal after said segments have been removed therefrom.

3. A system as described in claim 1 further comprising means for storing said segments without the rest of said video signal.

4. A system as described in claim 1 further comprising means for separately storing said segments and the rest of said video signal.

5. A system as described in claim 1 wherein said predetermined characteristics include the presence of a black frame before and after said segment.

6. A system as described in claim 1 wherein said predetermined characteristics include the presence of a predetermined video internal time code cue.

7. A system as described in claim 1 wherein said predetermined characteristics include the presence of a higher average audio level.

8. A system as described in claim 7 wherein said audio level is at least 3% higher than that of the immediately preceding portion of the video signal.

9. A system as described in claim 8, wherein the increase in the audio level is between 3% and 6% of that of the immediately preceding portion of the video signal.

10. A system as described in claim 1, wherein said predetermined characteristics include a predetermined duration for such segments.

11. A system as described in claim 10, wherein said duration is 15 seconds or a multiple thereof.

12. A system as described in claim 1 further comprising means to store said segments in a database.

13. A system as described in claim 12 further comprising means to store predetermined information relating to said segments in a database.

14. A system as described in claim 13 wherein said information includes the source, the start time and date, the end time and date, a summary of the content of the segment.

15. A system as described in claim 12 further comprising means to store frames extracted from each said segment at predetermined time intervals.

16. A system as described in claim 15 further comprising means to store predetermined information relating to said segments in a database.

17. A system as described in claim 16 wherein said information includes the source, the start time and date, the end time and date, a summary of the content of the segment.

19. A method as described in claim 18 further comprising the following steps:

a. storing said segments in a database,

b. storing said characteristics in a database,

20. A method as described in claim 18 wherein a signature is created for each segment with the use of frames taken at predetermined internals between the start and the end of each segment.

21. A method as described in claim 20 wherein each signature is stored in a database.

22. A method as described in claim 21 wherein said segments are selectively from said database.

18. A method for tracking and retrieving adverting segments from a television signal comprising the steps of:

a. converting, if necessary, the television signal to a digital format,

b. storing said digital television signal in a database,

c. scanning the television signal for the presence of predetermined characteristics,

d. identifying the start and end of such advertising segments with the use of such characteristics.
