Methods and systems for arranging and searching a database of media content recordings
View Patent ↗Methods and systems for arranging and searching a database of media content recordings are provided. In one example, a method is provided that comprises receiving a sample of media content, and performing, by a computing device, a content recognition of the sample of media content using a data file including a concatenation of representations for each of a plurality of media content recordings. In other examples, another method is provided that comprises receiving media content recordings, determining a representation for each media content recording, concatenating by a computing device the representation for each media content recording as a data file, and storing by the computing device a mapping between an identifier for a respective media content recording and a global position in the data file that corresponds to the representation of the respective media content recording.
1. A method comprising:
receiving media content recordings, each having an identifier identifying the media content recording;
determining a representation for each media content recording;
concatenating, by a computing device, the representation for each media content recording as a data structure; and
storing, by the computing device, a mapping between the identifier for a respective media content recording and a global position in the data structure that corresponds to the representation of the respective media content recording.
2. The method of claim 1 , wherein determining the representation for each media content recording comprises:
determining fingerprints of a respective media content recording at respective positions within the respective media content recording; and
wherein concatenating the representation for each media content recording as the data structure comprises: defining the representation as the fingerprints having corresponding global positions in the data structure.
3. The method of claim 1 , wherein the representation for a given media content recording comprises a fingerprint, and wherein the global position corresponds to a sound identifier of the given media content recording and a local landmark position of the fingerprint within the given media content recording.
4. The method of claim 1 , wherein the data structure has a concatenated timeline.
5. The method of claim 4 , wherein a given media content recording is represented as being located within the data structure along the concatenated timeline at a given position.
6. The method of claim 1 , further comprising providing a buffer between adjacent representations of media content recordings within the data structure.
7. The method of claim 1 , further comprising storing a list of global starting positions for media content recordings within the concatenated data structure to segment a global timeline of the data structure according to the media content recordings.
8. The method of claim 1 , further comprising storing a list of boundaries between each representation of media content recording within the concatenated data structure.
9. A non-transitory computer readable medium having stored therein instructions, that when executed by a computing device, cause the computing device to perform functions comprising:
receiving media content recordings, each having an identifier identifying the media content recording;
determining a representation for each media content recording;
concatenating the representation for each media content recording as a data structure; and
storing a mapping between the identifier for a respective media content recording and a global position in the data structure that corresponds to the representation of the respective media content recording.
10. The non-transitory computer readable medium of claim 9 , wherein determining the representation for each media content recording comprises:
determining fingerprints of a respective media content recording at respective positions within the respective media content recording; and
wherein concatenating the representation for each media content recording as the data structure comprises: defining the representation as the fingerprints having corresponding global positions in the data structure.
11. The non-transitory computer readable medium of claim 9 , wherein the representation for a given media content recording comprises a fingerprint, and wherein the global position corresponds to a sound identifier of the given media content recording and a local landmark position of the fingerprint within the given media content recording.
12. The non-transitory computer readable medium of claim 9 , wherein the data structure has a concatenated timeline, and wherein a given media content recording is represented as being located within the data structure along the concatenated timeline at a given position.
13. The non-transitory computer readable medium of claim 9 , wherein the functions further comprise providing a buffer between adjacent representations of media content recordings within the data structure.
14. The non-transitory computer readable medium of claim 9 , wherein the functions further comprise storing a list of global starting positions for media content recordings within the concatenated data structure to segment a global timeline of the data structure according to the media content recordings.
15. A system comprising:
at least one processor; and
data storage configured to store instructions that when executed by the at least one processor cause the system to perform functions comprising:
receiving media content recordings, each having an identifier identifying the media content recording;
determining a representation for each media content recording;
concatenating the representation for each media content recording as a data structure; and
storing a mapping between the identifier for a respective media content recording and a global position in the data structure that corresponds to the representation of the respective media content recording.
16. The system of claim 15 , wherein determining the representation for each media content recording comprises:
determining fingerprints of a respective media content recording at respective positions within the respective media content recording; and
wherein concatenating the representation for each media content recording as the data structure comprises: defining the representation as the fingerprints having corresponding global positions in the data structure.
17. The system of claim 15 , wherein the representation for a given media content recording comprises a fingerprint, and wherein the global position corresponds to a sound identifier of the given media content recording and a local landmark position of the fingerprint within the given media content recording.
18. The system of claim 15 , wherein the data structure has a concatenated timeline, and wherein a given media content recording is represented as being located within the data structure along the concatenated timeline at a given position.
19. The system of claim 15 , wherein the functions further comprise providing a buffer between adjacent representations of media content recordings within the data structure.
20. The system of claim 15 , wherein the functions further comprise storing a list of global starting positions for media content recordings within the concatenated data structure to segment a global timeline of the data structure according to the media content recordings.
