Abstract: Assemblies, systems, and media for providing proof of play information for content items displayed at electronic display assemblies are provided. A unit controller electronically interposed between a media player and an electronic display generates redundancy check codes from the content items actually transmitted to the display, such that a consistent code recurs while a given content item continues to be displayed. When a consistent code is generated consecutively, a play count for that content item is incremented, and an uninterrupted run of consecutive consistent codes is counted as a single play. Play counts are maintained over time, and a duration of play is determined from the first and last times a consistent code is generated. The codes, play counts, durations, and compressed copies of the content items may be stored and reported to remote devices.

Abstract: A display assembly includes a first and second subassembly attached to a structural framework, at least one of which includes an electronic display layer and a cover positioned forward of the electronic display layer, and each of which includes an airflow passageway. A rear passageway between the subassemblies provides an open space extending along rear surfaces of the subassemblies and fluidly connecting the airflow passageways, together forming a closed airflow pathway for a circulating gas. A fan unit located in the rear passageway and associated with each subassembly moves the circulating gas from the rear passageway into the airflow passageway of the associated subassembly. The subassemblies may be mounted on opposing sides of the structural framework, and activation of the fan units may generate a relatively turbulent flow within the rear passageway and a relatively laminar flow within the airflow passageways.

Abstract: A display assembly providing proof of play information is disclosed. Content items, including static content files, each of which comprises a single image for display in each play instance for a period of consecutive seconds, are displayed at electronic display, at least in part by way of a media player. A unit controller causes a cumulative play count for each of the content items to be stored and maintained over time, redundancy check codes to be generated for the content items such that a respective code is consistently generated for each of the content items, and is consistently and consecutively generated for each of the static content items in each of the play instances, and where a consistent redundancy check code is consecutively generated for a respective one of the content items in a respective one of the play instances, cause the play count associated therewith to be incremented.

Abstract: Systems and methods for automated, artificial intelligence (“AI”) based monitoring of, and alerting for, digital out of home display units are disclosed. The display units are installed at various geographic locations and each include a display subassembly connected to a structural subassembly, sensors for measuring conditions, airflow pathways with fans, and electronics for operation and control. A monitoring subsystem receives data from the display units, including sensor and operational status data, tags the data with a unique identifier, and analyzes the data using an AI model to identify if the data indicates that any of the display units are experiencing abnormal conditions or maintenance needs. The AI model is trained on historical data including sensor and operational status data from same or different display units tagged as normal or abnormal. The monitoring subsystem generates an alert and electronic service request for the abnormal conditions and maintenance needs.
