Claim 6:
7. A system for providing proof of play information, said system comprising:
a plurality of electronic display assemblies, each comprising:
an electronic display configured to display content items, wherein each of the content items comprise one or more images, wherein at least some of the content items comprise static content items, each of said static content items comprising a single one of the images;
a media player;
a unit controller comprising one or more electronic storage device and one or more processors, wherein said unit controller is electronically interposed between the media player and the electronic display, wherein said unit controller comprises a proof of play module configured to record electronic image data transmitted from the media player to the electronic display; and
a network connectivity device;

one or more databases configured to store the electronic image data received from the plurality of electronic display assemblies by way of the network connectivity devices, and
a second proof of play module associated with the one or more databases;
wherein at least one of the proof of play modules is configured to consecutively generate a plurality of consistent CRC codes for each of the static content items displayed at a respective one of the electronic displays of a respective one of the plurality of electronic display assemblies, and determine a duration of play for each of the static content items from the CRC codes by identifying a first time CRC code of the plurality of consistent CRC codes is generated for a respective one of the static content items and a last time the CRC code of the plurality of consistent CRC codes is generated for the respective one of the static content items, and recording a duration between the first time and the last time as a duration of play for the respective one of the static content items.
