1. A method for measuring usage of media data received at a user location, the media data being reproducible as comprehensible images or comprehensible sounds and having ancillary codes in at least some of the media data, comprising:

  • receiving the media data in a monitoring device at the user location;

    forming a data set in the monitoring device from the media data by including in the data set, data sufficient to decode the ancillary codes in the media data or to form a signature to identify the media data, while excluding from the data set, data required either to reproduce the comprehensible images or the comprehensible sounds;

    communicating the data set to a processing system located remotely from the user location; and

    at the remotely located processing system, carrying out at least one of;

    (a) detecting the ancillary codes based on the data set; and

    (b) producing a signature characterizing the media data based on the data set and matching the produced signature with a reference signature associated with identification data for the media data.
