Abstract
A method and system for distributing images for display by client systems. A distribution system includes an image server system that is connected to image client systems via a communications link, such as the Internet. The image server system is responsible for providing image packages to the image client systems and for collecting information from the image client systems. Each image client system periodically sends a heartbeat communication to the image server system. Upon receiving a heartbeat communication, the image server system determines the state of the image client system that sent the heartbeat communication and responds appropriately. The response may include instructions for the image client system to retrieve new images, to retrieve software updates, to send usage data, and so on.
