Abstract

Local advertisement insertion detection is described. In embodiment(s), a video feed of television media content can be received for distribution to media devices, and the video feed can include national advertisements and spliced-in local advertisements. A splice point in the video feed can be detected that indicates where a local advertisement has been inserted into the video feed.

Claims

1. A method, comprising:

receiving a video feed of television media content for distribution to media devices, the video feed including national advertisements and spliced-in local advertisements; and

detecting a splice point in the video feed that indicates where a local advertisement has been inserted into the video feed.

2. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a forced quantization match of video of the local advertisement that has been inserted into the video feed.

3. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a video frame pattern change from the video feed to video of the local advertisement that has been inserted into the video feed.

4. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a timing clock change from the video feed to video of the local advertisement that has been inserted into the video feed.

5. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a change in picture group signaling from the video feed to video of the local advertisement that has been inserted into the video feed.

6. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a signature of insertion equipment that inserts the local advertisement into the video feed.

7. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a bit rate change from the video feed to video of the local advertisement that has been inserted into the video feed.

8. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting Extended Data Services (XDS) ancillary data discontinuity from the video feed to video of the local advertisement that has been inserted into the video feed.

9. A method as recited in claim 1, wherein detecting the splice point in the video feed includes detecting a change in an audio bit rate from the video feed to video of the local advertisement that has been inserted into the video feed.

10. A content distributor, comprising:

a media content server configured to receive a video feed of television media content for distribution to media devices, the video feed including national advertisements and spliced-in local advertisements; and

an insertion detection service configured to detect a splice point in the video feed that indicates where a local advertisement has been inserted into the video feed.

11. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a forced quantization match of video of the local advertisement that has been inserted into the video feed.

12. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a video frame pattern change from the video feed to video of the local advertisement that has been inserted into the video feed.

13. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a timing clock change from the video feed to video of the local advertisement that has been inserted into the video feed.

14. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a change in picture group signaling from the video feed to video of the local advertisement that has been inserted into the video feed.

15. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a signature of insertion equipment that inserts the local advertisement into the video feed.

16. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a bit rate change from the video feed to video of the local advertisement that has been inserted into the video feed.

17. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as Extended Data Services (XDS) ancillary data discontinuity from the video feed to video of the local advertisement that has been inserted into the video feed.

18. A content distributor as recited in claim 10, wherein the insertion detection service is further configured to detect the splice point as a change in an audio bit rate from the video feed to video of the local advertisement that has been inserted into the video feed.

19. One or more computer-readable media comprising computer-executable instructions that, when executed, direct a content distributor to:

receive a video feed of television media content for distribution to media devices, the video feed including national advertisements and spliced-in local advertisements; and

detect a splice point in the video feed that indicates where a local advertisement as been inserted into the video feed.

20. One or more computer-readable media as recited in claim 19, further comprising computer-executable instructions that, when executed, direct the content distributor to detect that a national advertisement has been inserted into the video feed at the splice point after the video feed is received.
