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.
