The invention relates to method and apparatus for controlling a graphics engine, the graphics engine being suitable for creating graphics in a broadcast system. The apparatus generates a user interface allowing a user to control a graphics engine. The apparatus has a first input for receiving at least one template data element, the template data element including a graphics component and a data field component suitable for receiving an information unit. The apparatus further comprises a second input coupled to an information unit source. A processing unit coupled to the first input and second input processes the template data element and the information unit source to enter in the data field component is selected information unit to form a representation of a graphics page that results from a combination of the template data element and the selected information unit. The processing unit then generates a set of commands based on the representation of the graphics page, the set of commands being executable by the graphics engine to create an on-air graphics page in the television broadcast system. This invention is particularly useful in television broadcast systems and Internet broadcast systems. The invention also provides a computer readable storage medium containing a program element for implementing the apparatus for controlling a graphics engine.
