Abstract: A solution comprising cost-effective methods and techniques for converting a traditional vending machine into a vending machine with a graphical user interface, multimedia advertising and info kiosk capabilities. A key aspect of this invention is the integration of a consumer DVD player in a vending machine, in which the graphical user interface is implemented as DVD Menu structures stored on a DVD disc that also contains the video clips. Another aspect of this invention, is the changed logic of a traditional vending machine to delay item dispense until a video clip has been played. The present invention provides interfacing methods between a DVD player, a Vending Machine Controller and an optional microcontroller. These methods can be used to implement a communication protocol between a DVD player and a microcontroller. The methods and techniques of the invention can be integrated in an MDB peripheral device of a vending machine.
