Patent attributes
Methods, apparatus, systems, and articles of manufacture are disclosed to monitor on-demand media. An example apparatus populates a reference library with a reference profile for on-demand media in response to publication of the on-demand media by generating one or more reference signatures for the on-demand media, collecting reference metadata associated with the on-demand media, and associating the one or more reference signatures and the reference metadata in the reference library to generate the reference profile. Additionally, the example apparatus collects one or more sample signatures generated at a media presentation environment. The example apparatus also records an exposure for the on-demand media based on a match between the one or more sample signatures and the one or more reference signatures.
