METHODS AND APPARATUS TO DETECT ADVERTISEMENTS EMBEDDED IN ONLINE MEDIA
Methods and apparatus are disclosed to detect advertisements embedded in online media. Example methods disclosed herein determine a first time associated with an event notification embedded in a primary media. Examples disclosed herein determine, via a processor, a second time associated with a media feature of the primary media, and determine that secondary media is embedded in the primary media when a difference between the first time and the second time meets a threshold.
1 . A method comprising:
determining a first time associated with an event notification embedded in a primary media;
determining a second time associated with a media feature of the primary media; and
determining, via a processor, that secondary media is embedded in the primary media when a difference between the first time and the second time meets a threshold.
2 . The method of claim 1 , further comprising, extracting a portion of the secondary media in response to determining the secondary media is embedded in the primary media.
3 . The method of claim 2 , further comprising, determining, from the portion of the secondary media, the identity of the secondary media.
4 . (canceled)
5 . The method of claim 1 , wherein determining the first time associated with the event notification further comprises, extracting auxiliary data controlling the presence and location of the event notification.
6 . The method of claim 1 , wherein determining the first time associated with event notification further comprises:
determining a location of the event notification with respect to a progress bar associated the primary media;
obtaining a presentation time of the primary media;
determining a length of the progress bar, the length representative of the presentation time of the primary media;
determining a ratio of the location and the length; and
determining the first time associated with the event notification by multiplying the ratio and the presentation time.
7 . The method of claim 1 , further comprising, in response to determining that secondary media is embedded in the primary media, identifying the second time as a start time of the secondary media.
8 . The method of claim 7 , further comprising, in response to identifying the second time as a start time of the secondary media, determining an end time of the secondary media.
9 . (canceled)
10 . (canceled)
11 . The method of claim 1 , wherein the threshold is a window of time that denotes the event notification and the media feature are related.
12 . (canceled)
13 . A computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
determine a first time associated with an event notification embedded in a primary media;
determine a second time associated with a media feature of the primary media; and
determine that secondary media is embedded in the primary media when a difference between the first time and the second time meets a threshold.
14 . The computer readable storage medium of claim 13 , further comprising instructions that, when executed, cause the machine to at least extract a portion of the secondary media in response to determining the secondary media is embedded in the primary media.
15 . (canceled)
16 . The computer readable storage medium of claim 13 , further comprising instructions that, when executed, cause the machine to at least extract auxiliary data controlling the presence and location of the event notification.
17 . The computer readable storage medium of claim 13 , further comprising instructions that, when executed, cause the machine to at least:
determine a location of the event notification with respect to a progress bar associated the primary media;
obtain a presentation time of the primary media;
determine a length of the progress bar, the length representative of the presentation time of the primary media;
determine a ratio of the location and the length; and
determine the first time associated with the event notification by multiplying the ratio and the presentation time.
18 . The computer readable storage medium of claim 13 , further comprising instructions that, when executed, cause the machine to at least, identify the second time as a start time of the secondary media in response to determining that secondary media is embedded in the primary media.
19 . The computer readable storage medium of claim 18 , further comprising instructions that, when executed, cause the machine to at least, determine an end time of the secondary media in response to identifying the second time as a start time of the secondary media.
20 . (canceled)
21 . (canceled)
22 . The computer readable storage medium of claim 13 , wherein the threshold is a window of time that denotes the event notification and the media feature are related.
23 . (canceled)
24 . An apparatus comprising:
an event notification detector to determine a first time associated with an event notification embedded in a primary media;
a media feature detector to determine a second time associated with a media feature of the primary media; and
a correlator to determine that secondary media is embedded in the primary media when a difference between the first time and the second time meets a threshold.
25 . The apparatus of claim 24 , further comprising an extractor to extract a portion of the secondary media in response to determining the secondary media is embedded in the primary media.
26 . The apparatus of claim 24 , further comprising, an identifier to determine, from the portion of the secondary media, the identity of the secondary media.
27 . (canceled)
28 . The apparatus of claim 24 , wherein the event notification detector is further to extract auxiliary data controlling the presence and location of the event notification.
29 . The apparatus of claim 24 , wherein the event notification detector is further to:
determine a location of the event notification with respect to a progress bar associated the primary media;
obtain a presentation time of the primary media;
determine a length of the progress bar, the length representative of the presentation time of the primary media;
determine a ratio of the location and the length; and
determine the first time associated with the event notification by multiplying the ratio and the presentation time.
30 . The apparatus of claim 24 , wherein the correlator is further to identify the second time as a start time of the secondary media in response to determining that secondary media is embedded in the primary media.
31 . The apparatus of claim 30 , wherein the correlator is further to determine an end time of the secondary media in response to identifying the second time as a start time of the secondary media.
