Abstract

A method and system is provided for recognizing video content represented by temporally segmented video content. An example system includes a communication module and a search and match module. The communications module may be configured to receive a source table of contents (TOC) related to a temporally segmented video content. The source TOC may include one or more titles and a source playback length. The search and match module may be configured to interrogate a video products database with the source TOC to determine one or more match results, utilizing a fuzzy matching technique.

Claims

1. A computer-implemented system comprising:

a communications module to receive a source table of contents (TOC) related to temporally segmented video content, the source TOC comprising one or more titles and a source playback length; and

a search and match module to interrogate a database with the source TOC to determine one or more match results, utilizing a fuzzy matching technique.

2. The system of claim 1, wherein the search and match module comprises:

a match type detector to determine a match type associated with the received source TOC;

a candidate list generator to determine a list of candidate TOCs from a video product database, based on the type of the match request; and

a matching module to;

compare the source TOC to each candidate TOC from the list of candidate TOCs, utilizing a fuzzy matching technique; and

determine the one or more match results based on the results of the comparisons.

3. The system of claim 2, wherein the matching module is to identify a candidate TOC from the list of candidate TOCs as a match if:

the candidate TOC includes titles that match all titles from the source TOC;

a playback length from the candidate TOC is not identical to the source playback length; and

the playback length from the candidate TOC differs from the source playback length by a value not exceeding a threshold value.

4. The system of claim 2, wherein the matching module is to identify a candidate TOC from the list of candidate TOCs as a match if the candidate TOC includes a title that matches at least one title from the source TOC.

5. The system of claim 1, wherein a main title from the source TOC is associated with a plurality of chapters, wherein the matching module is to identify a candidate TOC from the list of candidate TOCs as a match if the candidate TOC includes a subset of the plurality of chapters.

6. The system of claim 1, comprising a verification module to eliminate potential false positive matches from the one or more match results.

7. The system of claim 1, wherein the temporally segmented video content is stored on one of:

a digital versatile disc (DVD);

a Blu-ray disc;

a High-Definition/Density (HD) DVD;

a Video Compact Disc (VCD);

a Super Video Compact Disc (sVCD); and

a Laserdisc.

8. The system of claim 1, wherein the temporally segmented video content corresponding to the source TOC is stored in a permanent memory of a computer system.

9. The system of claim 7, wherein the temporally segmented video content is stored on a video disc.

10. The system of claim 1, wherein the communications module is to receive a source TOC from a client computer system, via a network connection.

11. The system of claim 1, comprising a presentation generator to generate a presentation of the one or more match results.

13. The method of claim 11, wherein the interrogating of the database comprises:

determining a set of candidate TOCs from the database, utilizing the source TOC; and

comparing a candidate TOC from the set of candidate TOCs to the source TOC.

17. The method of claim 11, comprising applying a verification technique to the one or more match results to eliminate potential false positive matches.

20. The method of claim 11, wherein the temporally segmented video content is stored on a digital versatile disc (DVD) or a Blu-ray disc.

21. The method of claim 11, wherein the temporally segmented video content corresponding to the source TOC is stored in a permanent memory of a computer system.

12. A computer-implemented method comprising:

using one or more processors to perform operations of;

receiving a source table of contents (TOC) related to temporally segmented video content, the source TOC comprising one or more main titles and a source playback length; and

interrogating a database with the source TOC, utilizing a fuzzy matching technique, to determine one or more match results.

14. The method of claim 12, wherein the fuzzy matching technique comprises identifying a candidate TOC from the database as a match if:

the candidate TOC includes titles that match all titles from the source TOC;

a playback length associated with the candidate TOC is not identical to the source playback length; and

the playback length associated with the candidate TOC differs from the source playback length by a value not exceeding a threshold value.

15. The method of claim 12, wherein the fuzzy matching technique comprises identifying a candidate TOC from the database as a match if the candidate TOC includes at least one title that matches a title from the one or more main titles from the source TOC.

16. The method of claim 12, wherein:

a main title from the one or more main titles is associated with a plurality of chapters; and

the fuzzy matching technique comprises identifying a candidate TOC from the database as a match if the candidate TOC includes a subset of the plurality of chapters.

18. The method of claim 16, wherein the applying of the verification technique comprises:

determining an average difference between chapter lengths associated with the source TOC and corresponding chapter lengths associated with a suspect match result from the one or more match results;

determining that the average difference is greater than a threshold value; and

eliminating the suspect match result from the one or more match results.

19. The method of claim 16, wherein the applying of the verification technique comprises:

determining a set of values reflecting respective chapter length differences, a chapter length difference is a difference between a length of a chapter from the source TOC and a length of a corresponding chapter from a suspect match result from the one or more match results;

determining that a difference between a first value from the set of values and a second value from the set of values is greater than a threshold value; and

eliminating the suspect match result from the one or more match results.

22. A machine-readable medium having instruction data to cause a machine to:

receive a source table of contents (TOC) related to temporally segmented video content, the source TOC comprising one or more titles and a source playback length; and

interrogate a database with the source TOC to determine one or more match results, utilizing a fuzzy matching technique.
