Abstract

A system for discovering content and metadata includes a processor communicatively coupled to a communication network and a database. The processor determines whether an end portion of a portion of content has been received based on the portion of content and/or metadata. The processor generates a content fingerprint based on the portion of content if the end portion has been received. The content fingerprint and/or the metadata are stored in the database.

Claims

1. A method for discovering content and metadata, the method comprising steps of:

receiving at least one content stream that includes a plurality of portions of content; and

for each content stream;

determining, by a processor, whether an end portion of a currently received portion of content has been received based on at least one of the currently received portion of content and metadata;

generating, by the processor, a content fingerprint based on the currently received portion of content if the end portion has been received; and

storing, in a first database, at least one of the content fingerprint and the metadata.

2. The method of claim 1, further comprising a step of:

performing, by the processor, data-mining on at least one of the content fingerprint and the metadata stored in the first database.

3. The method of claim 1, wherein the metadata includes at least one of (1) metadata broadcasted in packets via a communication network, (2) metadata published in a text based format on a web site, and (3) metadata broadcasted as a voice over audio signal.

4. The method of claim 1, further comprising a step of:

storing, in the first database, at least one of (1) an identifier of a source of the portion of content, (2) an identifier of a source of the metadata, (3) a time of receipt of the portion of content, and (4) a time of receipt of the metadata.

5. The method of claim 2, wherein the performing data mining further comprises steps of:

matching at least two content fingerprints stored in the first database; and

aggregating the metadata corresponding to the at least two matched content fingerprints.

6. The method of claim 1, wherein the portion of content includes at least one of a portion of audio content and a portion of video content.

7. The method of claim 2, wherein the performing data mining further comprises steps of:

identifying approved metadata stored in the first database, and

transferring the approved metadata from the first database to a second database.

21. The method of claim 1, wherein, for each content stream, the plurality of portions of content include portions of different content.

22. The method of claim 1, wherein, for each content stream, the end portion indicates that a new portion of content will be received.

23. The method of claim 1, wherein, for each content stream, portions of new content are received during the generation of the content fingerprint.

24. The method of claim 1,

wherein, for each content stream, the currently received portion of content is stored in a buffer until the end portion is received, and in a case where the end portion is received, the content fingerprint is generated based on the currently received portion of content that is stored in the buffer,

wherein, for each content stream, portions of new content are received during the generation of the content fingerprint.

8. A system for discovering content and metadata, the system comprising at least one processor communicatively coupled to a communication network and a first database, wherein the processor is configured to:

receive at least one content stream that includes a plurality of portions of content; and

for each content stream;

determine whether an end portion of a currently received portion of content has been received based on at least one of the currently received portion of content and metadata;

generate a content fingerprint based on the currently received portion of content if the end portion has been received; and

store, in the first database, at least one of the content fingerprint and the metadata.

9. The system of claim 8, wherein the at least one processor is further configured to:

perform data-mining on at least one of the content fingerprint and the metadata stored in the first database.

10. The system of claim 8, wherein the metadata includes at least one of (1) metadata broadcasted in packets via the communication network, (2) metadata published in a text based format on a web site, and (3) metadata broadcasted as a voice over audio signal.

11. The system of claim 8, wherein the at least one processor is further configured to:

store, in the first database, at least one of (1) an identifier of a source of the portion of content, (2) an identifier of a source of the metadata, (3) a time of receipt of the portion of content, and (4) a time of receipt of the metadata.

12. The system of claim 9, wherein the at least one processor is further configured to:

match at least two content fingerprints stored in the first database; and

aggregate the metadata corresponding to the at least two matched content fingerprints.

13. The system of claim 8, wherein the portion of content includes at least one of a portion of audio content and a portion of video content.

14. The system of claim 9, wherein the at least one processor is further configured to:

identify approved metadata stored in the first database, and

transfer the approved metadata from the first database to a second database.

15. A non-transitory computer readable medium having stored thereon sequences of instructions, the sequences of instructions including instructions, which, when executed by a processor, cause the processor to perform:

receiving at least one content stream that includes a plurality of portions of content; and

for each content stream;

determining whether an end portion of a currently received portion of content has been received based on at least one of the currently received portion of content and metadata;

generating a content fingerprint based on the currently received portion of content if the end portion has been received; and

storing, in a first database, at least one of the content fingerprint and the metadata.

16. The computer readable medium of claim 15, wherein the sequences of instructions further include instructions, which, when executed by the processor, cause the processor to perform:

performing, by the processor, data-mining on at least one of the content fingerprint and the metadata stored in the first database.

17. The computer readable medium of claim 15, wherein the metadata includes at least one of (1) metadata broadcasted in packets via a communication network, (2) metadata published in a text based format on a web site, and (3) metadata broadcasted as a voice over audio signal.

18. The computer readable medium of claim 15, wherein the sequences of instructions further include instructions, which, when executed by the processor, cause the processor to perform:

storing, in the first database, at least one of (1) an identifier of a source of the portion of content, (2) an identifier of a source of the metadata, (3) a time of receipt of the portion of content, and (4) a time of receipt of the metadata.

19. The computer readable medium of claim 16, wherein the sequences of instructions further include instructions, which, when executed by the processor, cause the processor to perform:

matching at least two content fingerprints stored in the first database; and

aggregating the metadata corresponding to the at least two matched content fingerprints.

20. The computer readable medium of claim 16, wherein the sequences of instructions further include instructions, which, when executed by the processor, cause the processor to perform:

identifying approved metadata stored in the first database, and

transferring the approved metadata from the first database to a second database.
