Methods, systems, and media for synchronizing video streams

1. A method for synchronizing video streams, the method comprising:

identifying a target video stream and a reference video stream, wherein the target video stream and the reference video stream are two different broadcasts of a program;

generating, for the target video stream, a sequence of fingerprints;

determining a time shift at which the sequence of fingerprints appears within the reference video stream;

determining whether the target video stream is synchronized with the reference video stream by determining whether the time shift exceeds a predetermined threshold; and

in response to determining that the target video stream is not synchronized with the reference video stream, causing an electronic programming guide that includes an indication of the target video stream to be modified based on the time shift.

2. The method of claim 1 , further comprising transmitting an alert to an operator associated with the target video stream, wherein the alert indicates the time shift.

3. The method of claim 1 , further comprising determining an error type associated with the time shift.

4. The method of claim 3 , wherein the error type indicates that the target video stream did not begin at a correct time.

5. The method of claim 3 , wherein the error type indicates that the target video stream will not end at a correct time.

6. The method of claim 1 , further comprising:

identifying a second target video stream;

generating, for the second target video stream, a second sequence of fingerprints;

determining that the second sequence of fingerprints are not included in the reference video stream; and

in response to determining that the second sequence of fingerprints are not included in the reference video stream, determining that the second target video stream is not a broadcast of the program corresponding to the reference video stream.

7. The method of claim 1 , wherein the target video stream is identified based on metadata associated with the target video stream.

8. A system for synchronizing video streams, the system comprising:

a hardware processor that is configured to:

identify a target video stream and a reference video stream, wherein the target video stream and the reference video stream are two different broadcasts of a program;

generate, for the target video stream, a sequence of fingerprints;

determine a time shift at which the sequence of fingerprints appears within the reference video stream;

determine whether the target video stream is synchronized with the reference video stream by determining whether the time shift exceeds a predetermined threshold; and

in response to determining that the target video stream is not synchronized with the reference video stream, cause an electronic programming guide that includes an indication of the target video stream to be modified based on the time shift.

9. The system of claim 8 , wherein the hardware processor is further configured to transmit an alert to an operator associated with the target video stream, wherein the alert indicates the time shift.

10. The system of claim 8 , wherein the hardware processor is further configured to determine an error type associated with the time shift.

11. The system of claim 10 , wherein the error type indicates that the target video stream did not begin at a correct time.

12. The system of claim 10 , wherein the error type indicates that the target video stream will not end at a correct time.

13. The system of claim 8 , wherein the hardware processor is further configured to:

identify a second target video stream;

generate, for the second target video stream, a second sequence of fingerprints;

determine that the second sequence of fingerprints are not included in the reference video stream; and

in response to determining that the second sequence of fingerprints are not included in the reference video stream, determine that the second target video stream is not a broadcast of the program corresponding to the reference video stream.

14. The system of claim 8 , wherein the target video stream is identified based on metadata associated with the target video stream.

15. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for synchronizing video streams, the method comprising:

identifying a target video stream and a reference video stream, wherein the target video stream and the reference video stream are two different broadcasts of a program;

generating, for the target video stream, a sequence of fingerprints;

determining a time shift at which the sequence of fingerprints appears within the reference video stream;

determining whether the target video stream is synchronized with the reference video stream by determining whether the time shift exceeds a predetermined threshold; and

in response to determining that the target video stream is not synchronized with the reference video stream, causing an electronic programming guide that includes an indication of the target video stream to be modified based on the time shift.

16. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises transmitting an alert to an operator associated with the target video stream, wherein the alert indicates the time shift.

17. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises determining an error type associated with the time shift.

18. The non-transitory computer-readable medium of claim 17 , wherein the error type indicates that the target video stream did not begin at a correct time.

19. The non-transitory computer-readable medium of claim 17 , wherein the error type indicates that the target video stream will not end at a correct time.

20. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises:

identifying a second target video stream;

generating, for the second target video stream, a second sequence of fingerprints;

determining that the second sequence of fingerprints are not included in the reference video stream; and

in response to determining that the second sequence of fingerprints are not included in the reference video stream, determining that the second target video stream is not a broadcast of the program corresponding to the reference video stream.

21. The non-transitory computer-readable medium of claim 15 , wherein the target video stream is identified based on metadata associated with the target video stream.
