Abstract

Methods and apparatus to measure exposure to streaming media are disclosed. An example method includes extracting a tag from a first media part, the tag corresponding to a playback position in a second media part, the first and second parts being portions of a first item of media; when playback of the first part is completed, detecting a third media part that is not part of the first item of media; in response to completion of playback of the first part or detecting the third part, storing a first duration of the first part as an offset value; when playback of the third part is completed, detecting the second part; while the second part is being played, looking up the tag when the playback position is traversed, traversal of the playback position being identified based on the offset value; and sending the tag to an entity.

First claim

What is claimed is:

1 . A method, comprising:
extracting a metadata tag from a first media part, the metadata tag corresponding to a playback position in a second media part, the first and second media parts being portions of a first item of media; when playback of the first media part is completed, detecting a third media part that is not part of the first item of media; in response to completion of playback of the first media part or detecting the third media part, storing a first duration of the first media part as an offset value; when playback of the third media part is completed, detecting the second media part; while the second media part is being played, looking up the metadata tag when the playback position is traversed, traversal of the playback position being identified based on the offset value; and sending the metadata tag to an audience measurement entity based on the looking up of the metadata tag.

2 . A method as defined in claim 1 , further including:
when playback of the second media part is completed, detecting a fourth media part that is not part of the first item of media; in response to completion of playback of the second media part or detecting the fourth media part, setting the offset value based on the first duration and a second duration of the second media part; when playback of the fourth media part is completed, detecting a fifth media part that is a portion of the first item of media, a second metadata tag corresponding to a second playback position within a third duration of the fifth media part; and while the fifth media part is being played, looking up the second metadata tag when the second playback position is traversed, traversal of the second playback position being identified based on the offset value.

3 . A method as defined in claim 1 , further including storing the metadata tag in a data structure using playback position as a lookup key.

4 . A method as defined in claim 1 , wherein the detecting of the third media part includes detecting a media insertion marker.

5 . A method as defined in claim 4 , wherein the metadata tag is associated with the audience measurement entity, and the detecting of the third media part further includes determining that the third media part does not have metadata tags associated with the audience measurement entity.

6 . A method as defined in claim 1 , wherein the sending of the metadata tag to the audience measurement entity is in response to traversal of the playback position.

7 . A method as defined in claim 1 , further including sending a request for the first media part to a server via a communications network, and receiving instructions to perform the extracting of the metadata tag, the detecting of the third media part, the storing of the first duration, the detecting of the second media part, and the looking up of the metadata tag being in a response to the request.

8 . A method as defined in claim 1 , further including, while the first media part is being played, looking up a second metadata tag that corresponds to a second playback position in the first media part when the second playback position is traversed, the second playback position being based on the portion of the first media part being played.

9 . An apparatus, comprising:
a media presenter to present media; a metadata retriever to:
extract a metadata tag from a first media part, the metadata tag corresponding to a playback position in a second media part, the first and second media parts being portions of a first item of media; and
while the second media part is being played, look up the metadata tag when the playback position is traversed, traversal of the playback position being identified based on an offset value;
a file detector to:
when playback of the first media part is completed, detect a third media part that is not part of the first item of media; and
when playback of the third media part is completed, detect the second media part;
a duration setter to, in response to completion of playback of the first media part or detecting the third media part, store a first duration of the first media part as the offset value; and a transmitter to send the metadata tag to an audience measurement entity based on the looking up of the metadata tag.

10 . An apparatus as defined in claim 9 , further including a structure generator to store the extracted metadata tag in a data structure using the playback position as a lookup key, the metadata retriever to look up the metadata tag in the data structure.

11 . An apparatus as defined in claim 9 , wherein the file detector is to determine whether the second media part is part of the first item of media and to determine whether third media part is part of the first item of media.

12 . An apparatus as defined in claim 9 , further including a metadata converter to convert a uniform resource locator in the metadata tag into a request for the uniform resource locator.

13 . An apparatus as defined in claim 9 , wherein the metadata retriever is to, while the first media part is being played, looking up a second metadata tag that corresponds to a second playback position in the first media part when the second playback position is traversed, the second playback position being based on the portion of the first media part being played.

14 . An apparatus as defined in claim 9 , wherein the file detector is to detect the third media part by detecting a media insertion marker.

15 . An apparatus as defined in claim 14 , wherein the metadata tag is associated with the audience measurement entity, and the file detector is to detect the third media part by determining that the third media part does not have metadata tags associated with the audience measurement entity.

16 . A tangible computer readable storage medium comprising computer readable instructions which, when executed, cause a processor to at least:
extract a metadata tag from a first media part, the metadata tag corresponding to a playback position in a second media part, the first and second media parts being portions of a first item of media; when playback of the first media part is completed, detect a third media part that is not part of the first item of media; in response to completion of playback of the first media part or detection of the third media part, store a first duration of the first media part as an offset value; when playback of the third media part is completed, detect the second media part; while the second media part is being played, look up the metadata tag when the playback position is traversed, traversal of the playback position being identified based on the offset value; and send the metadata tag to an audience measurement entity based on the looking up of the metadata tag.

17 . A storage medium as defined in claim 16 , wherein the instructions are further to cause the processor to:
when playback of the second media part is completed, detect a fourth media part that is not part of the first item of media; in response to completion of playback of the second media part or detection of the fourth media part, set the offset value based on the first duration and a second duration of the second media part; when playback of the fourth media part is completed, detect a fifth media part that is a portion of the first item of media, a second metadata tag corresponding to a second playback position within a third duration of the fifth media part; and while the fifth media part is being played, look up the second metadata tag when the second playback position is traversed,
