Abstract

Methods and apparatus for monitoring locally inserted media content are disclosed. A disclosed method includes obtaining identification data and inserting the identification data in the media content after the media content has been received at a media consumption location. Another disclosed method includes receiving media content before the media content is output by a consumer receiving device and monitoring the received media content.
Monitoring the received media content may include extracting signatures from the received media content and transmitting the extracted signatures to another location.

6. A method as defined in claim 1, wherein the identification data is inserted in a frequency range shared with a frequency range of the media content.
7. A method of identifying locally inserted media content, comprising:
receiving media content before the media content is output by a consumer receiving device; and monitoring the received media content.
8. A method as defined in claim 7, wherein monitoring the received media content is performed at at least one of an output of an editing station, an output of a post production transmitter, an output of a major distribution point receiver, an output of a major distribution point transmitter, an entry to a consumption location, an output of an end user distribution network, an output of a conditional access unit of the consumer receiving device, or an output of a decoder of the consumer receiving device.
9. A method as defined in claim 8, wherein monitoring the media content comprises at least one of extracting identification data inserted into the media content, identifying transitions between media content, or extracting signatures of media segments.
10. A method as defined in claim 9, wherein identifying transitions between media content comprises at least one of identifying changes in identification data inserted in the media content, identifying a presence or absence of a media packet identifier, identifying a change in the repetition rate of the media packet identifier, identifying a change in a mapping of media content components, identifying a change in metadata associated with the media content, identifying the presence or absence of errors associated with the media content, or identifying changes in a state of a set-top box.
11. A method as defined in claim 9, wherein the identification data inserted into the media content is at least one of tags inserted for the purpose of metering media content or identification data inserted for the purpose of distributing media content to consumption locations.
