Claim 12:
13. A method for providing proof of play information for static content items displayed at electronic display assemblies, said method comprising the steps of:
consecutively generating a plurality of consistent CRC codes from data regarding each of the static content items transmitted from a media player of a respective one of the electronic display assemblies to an electronic display of the respective one of the electronic display assemblies at a proof of play module provided at a unit controller, said unit controller comprising one or more electronic storage device and one or more processors, wherein said unit controller is interposed between the media player and the electronic display of the respective one of the electronic display assemblies;
determining a duration of play for each of the static content items by:
recording a first time one of the plurality of consistent CRC codes is generated in a given instance as a start time;
recording a last time the one of the plurality of consistent CRC is generated in the given instance as an end time; and
deriving an elapsed time between the start time and the end time;

transmitting each not immediately repeated one of the plurality of consistent CRC codes (“content CRC codes”) from each of the electronic display assemblies to a database comprising a plurality of play count entries, each associated with a stored CRC code;
increasing each of the plurality of play count entries associated with a respective one of the stored CRC codes matching a respective one of the content CRC codes received by one unit for each instance the respective one of the content CRC codes is received at the database; and
storing the duration of play at the database in association with a matching one of the stored CRC codes.
