Digital television Broadcast Systems have video, audio and data functions which are used to create services for both i.) video and audio customers and ii.) interactive television (iTV) customers. iTV services in a number of different forms are recently supplementing the historic linear video/audio broadcast. The addition of iTV services to the digital television services suite changes the nature and scope of end user access rights and privileges with their related time based rules. The invention is an interactive television security application which provides for appropriate commercial rights and privilege management with respect to the right to play or view the interactive TV services and the digital television's video, audio and data functions.
