Abstract

Systems and methods for matching live media content are disclosed. At a server, obtaining first media content from a client device, herein the first media content corresponds to a portion of media content being played on the client device, and the first media content is associated with a predefined expiration time; obtaining second media content from one or more content feeds, wherein the second media content also corresponds to a portion of the media content being played on the client device; in accordance with a determination that the second media content corresponds to a portion of the media content that has been played on the client device: before the predefined expiration time, obtaining third media content corresponding to the media content being played on the client device, from the one or more content feeds; and comparing the first media content with the third media content.

in accordance with a determination that the second media content corresponds to a portion of the media content that has not yet been played on the client device;

after a predefined time interval,

obtaining, from the client device, fourth media content corresponding to the media content being played on the client device; and

comparing the second media content with the fourth media content.

3. The method of claim 1, wherein

the first and second media content are two portions of the media content being played on the client device;

and

the first media content is a subsequent portion of the media content to the second portion.

4. The method of claim 1, wherein the first media content and the second media content are obtained at a same predefined time, and

the determination that the second media content corresponds to a portion of the media content that has been played on the client device comprises:

comparing the first content media content with the second media content.

5. The method of claim 1, further comprising:

obtaining a first content fingerprint using the first media content; and

obtaining a third content fingerprint using the third media content.

6. The method of claim 5, wherein comparing the first media content with the third media content comprising:

comparing the first content fingerprint with the third content fingerprint.

7. The method of claim 5, wherein a content fingerprint includes information that identifies a portion of media content.

8. The method of claim 5, wherein the content fingerprint includes at least one of:

average zero cross rate, estimate tempo, average spectrum, spectral flatness, prominent tones cross a set of bands, and bandwidth.

9. The method of claim 1, wherein the media content is one of:

a clip of a video or audio steam, or a predefined number of frames of the video stream.

10. A server system, comprising:

one or more processors;

memory; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for;

obtaining first media content from a client device, wherein the first media content corresponds to a portion of media content being played on the client device, and the first media content is associated with a predefined expiration time;

obtaining second media content from one or more content feeds, wherein the second media content also corresponds to a portion of the media content being played on the client device;

in accordance with a determination that the second media content corresponds to a portion of the media content that has been played on the client device;

before the predefined expiration time,

obtaining third media content corresponding to the media content being played on the client device, from the one or more content feeds; and

matching the first media content with the third media content.

11. The server system of claim 10, wherein the one or more programs further comprising instruction for:

in accordance with a determination that the second media content corresponds to a portion of the media content that has not yet been played on the client device;

after a predefined time interval,

obtaining, from the client device, fourth media content corresponding to the media content being played on the client device; and

comparing the second media content with the fourth media content.

12. The server system of claim 10, wherein

the first and second media content are two portions of the media content being played on the client device;

and

the first media content is a subsequent portion of the media content to the second portion.

13. The server system of claim 10, wherein the first media content and the second media content are obtained at a same predefined time, and
