Abstract: An advertising support system includes an operation center, numerous display systems and one or more client services systems. The operation center is a platform that provides a collection of services and capabilities. For example, the operation center is responsible for assuring that the content is displayed on the display systems at required times and locations. The system may accommodate multiple operation centers in multiple geographical locations to provide failure recovery and to provide services over geographically diverse locations. A variety of services are provided by the operation center to support its operations and the display systems. For example, the operation center populates and maintains a current and archival database, which includes status, content, fault and maintenance logs, and other data of display systems. Numerous services may be provided through the client services systems.
