Patent attributes
A system has a display device attached to an automobile, with a display screen visible outside the automobile. Workstations specify location-based rules regarding image content to be displayed in specified geographic areas at specific times, and further specify a predetermined threshold of a number of automobiles that display a given threshold-limited image. An application server determines from the location-based rules a dynamic content schedule of image content to display at the display device when the automobile is in the given geographic region at a given display time. When the predetermined threshold of the number of automobiles displaying the threshold-limited image in the given geographic region is reached, an update to the dynamic content schedule is generated including a different image in place of the threshold-limited image, and a current image corresponding to the updated dynamic content schedule is displayed.
