1. A method to monitor presentation of video-on-demand (VOD) content comprising:
- obtaining subscriber metering data from a site metering device monitoring presentation of VOD content at a first subscriber site;
obtaining server metering data from a VOD server, the server metering data representative of a plurality of VOD content provided by the VOD server to a plurality of subscriber sites, the server metering data including identification information for the plurality of subscriber sites to identify particular VOD content provided to each of the plurality of subscriber sites, the identification information manipulated to preserve anonymity of the plurality of subscriber sites;
using a metering device identifier included in the subscriber metering data to obtain a first identifier and a second identifier associated with the first subscriber site, the first identifier and the second identifier being different from the metering device identifier and being obtained from data separate from the subscriber metering data and the server metering data, the metering device identifier identifying the site metering device, the first identifier comprising a media device identifier identifying a media device, the media device being different from the site metering device, the media device being used to present the VOD content at the first subscriber site, and the second identifier comprising subscriber identification information other than the media device identifier and the metering device identifier;
combining and manipulating at least the first identifier and the second identifier to determine a first manipulated identifier to identify the first subscriber site, the first manipulated identifier capable of matching a second manipulated identifier for the first subscriber site included in the manipulated identification information of the server metering data to identify a portion of the server metering data that is uniquely associated with the first subscriber site; and
using the first manipulated identifier to cross-reference the manipulated identification information included in the server metering data to merge the subscriber metering data and the portion of the server metering data uniquely associated with the first subscriber site.
