Abstract

A method and system for playlist generation is disclosed. In one aspect, the system may include at least one analysis module for receiving and analyzing an unknown work and generating a corresponding representation thereof, and at least one identification (ID) server for receiving the representation from the analysis modules and determining the identity of the unknown work.

Claims

1. A method comprising:

receiving, by a processor, a plurality of segment representations generated from a plurality of segments of a portion of audio data of a broadcast signal over a network, wherein the portion of audio data comprises a plurality of unknown works, and wherein the plurality of segments comprise portions of the plurality of unknown works;

identifying, by the processor, the plurality of unknown works based on identifying one or more of the segment representations that correspond to one or more segments of a plurality of reference works; and

updating, by the processor, separate playlists for two or more of the identified works, the separate playlists each identifying broadcast instances of an associated identified work.

2. The method of claim 1, further comprising:

outputting identification of the one or more segment representations that correspond to the one or more segments of the plurality of reference works responsive to identifying the one or more segment representations that correspond to the one or more segments of the plurality of reference works to enable a remote device to purge the one or more segment representations that correspond to the one or more segments of the plurality of reference works.

3. The method of claim 1, wherein the segment representations comprise at least one of feature vectors, spectral representations, text output of a speech recognition system, a musical score output of a music transcription system, or bit calculated keys.

4. The method of claim 1, wherein the segment representations are received as a batch at a predetermined time interval.

5. The method of claim 1, wherein updating the separate playlists comprises updating one playlist of the separate playlists with the identification of the one or more of the segment representations that correspond to the one or more segments of the plurality of reference works responsive to identifying a broadcast instance of the associated identified work, wherein the one playlist is associated with a single work.

6. The method of claim 1, wherein the portion of audio data comprises unknown portions of the plurality of unknown works with unknown boundaries between the plurality of unknown works.

7. The method of claim 1, wherein the segment representations are received from a plurality of remote devices.

8. The method of claim 1, wherein the segment representations are received and the separate playlists are updated in near real-time.

9. The method of claim 1, wherein the segment representations are received and the separate playlists are updated in real-time.

10. The method of claim 1, wherein the segment representations are received from one or more remote devices, the method further comprising:

transmit information regarding the identified works to a third party server.

11. A system comprising:

a first computing device comprising a memory, a processor coupled to the memory, and an identification server executed from the memory by the processor to;

receive a plurality of segment representations generated from a plurality of segments of a portion of audio data of a broadcast signal over a network, wherein the portion of audio data comprises a plurality of unknown works, and wherein the plurality of segments comprise portions of the plurality of unknown works;

identify the plurality of unknown works based on identifying one or more of the segment representations that correspond to one or more segments of a plurality of reference works; and

update separate playlists for two or more of the identified works, the separate playlists each identifying broadcast instances of an associated identified work.

12. The system of claim 11, wherein the processor is further to:

output identification of the one or more segment representations that correspond to the one or more segments of the plurality of reference works responsive to identifying the one or more segment representations that correspond to the one or more segments of the plurality of reference works to enable a remote device to purge the one or more segment representations that correspond to the one or more segments of the plurality of reference works.

13. The system of claim 11, wherein the segment representations comprise at least one of feature vectors, spectral representations, text output of a speech recognition system, a musical score output of a music transcription system, or bit calculated keys.

14. The system of claim 11, wherein the portion of audio data comprises unknown portions of the plurality of unknown works with unknown boundaries between the plurality of unknown works.

15. The system of claim 11, further comprising

a second computing device, networked to the first computing device, the second computing device to:

receive the portion of audio data of a broadcast signal;

generate the plurality of segment representations from the portion of audio data; and

transmit the plurality of segment representations over the network to the first computing device.

16. A non-transitory computer readable medium comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:

receiving, by the processor, a plurality of segment representations generated from a plurality of segments of a portion of audio data of a broadcast signal over a network, wherein the portion of audio data comprises a plurality of unknown works, and wherein the plurality of segments comprise portions of the plurality of unknown works;

identifying, by the processor, the plurality of unknown works based on identifying one or more of the segment representations that correspond to one or more segments of a plurality of reference works; and

updating, by the processor, separate playlists for two or more of the identified works, the separate playlists each identifying broadcast instances of an associated identified work.

17. The non-transitory computer readable medium of claim 16, the operations further comprising:

outputting identification of the one or more segment representations that correspond to the one or more segments of the plurality of reference works responsive to identifying the one or more segment representations that correspond to the one or more segments of the plurality of reference works to enable a remote device to purge the one or more segment representations that correspond to the one or more segments of the plurality of reference works.

18. The non-transitory computer readable medium of claim 16, wherein the segment representations comprise at least one of feature vectors, spectral representations, text output of a speech recognition system, a musical score output of a music transcription system, or bit calculated keys.

19. The non-transitory computer readable medium of claim 16, wherein the portion of audio data comprises unknown portions of the plurality of unknown works with unknown boundaries between the plurality of unknown works.

20. The non-transitory computer readable medium of claim 16, wherein the segment representations are received from a plurality of remote devices in near-real time, and wherein the separate playlists are updated in near real-time.
