Methods and apparatus for monitoring the insertion of local media content into a program stream

摘要

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.

1. A method for identifying locally inserted media, the method comprising:
monitoring a primary media signal at a consumer location, the primary media signal carrying at least one of audio or video; after local media has been spliced into the primary media signal, by a first device at the consumer location to generate a modified media signal, analyzing the modified media signal at a second device at the consumer location to detect insertion of the local media into the modified media signal, the local media carrying at least audio or video to be presented by a media presentation device at the consumer location, wherein the first device is separate from the second device; and responsive to detecting that the local media has been spliced into the primary media signal, transforming the modified media signal into a tagged signal by inserting identification data, identifying the local media, into the modified media signal after the local media has been inserted into the primary media signal, the identification data indicating that the local media was spliced into the primary media signal after the primary media signal was received at the consumer location.
