Abstract
The present invention utilizes a graphics layout language that is defined by the broadcaster or the studio to control the layout of graphic overlays in relation to corresponding images presented on a display. Each user interface component is divided into objects that define their individual behaviors and presentations. Data files using the hypertext markup language, HTML, layout these objects on the screen. By varying the HTML data files, control is provided to the broadcaster over what objects are displayed on the screen, where they are placed on the screen, and to a limited effect, their behavior. This can be accomplished without re-writing the executables as would be necessary in other television type user interface implementations.
