Abstract
Controlling the admission of interactive television iTV applications to an iTV application distribution system is accomplished through the use of iTV application profiles that enumerate sets of allowed functions and behaviors for the iTV applications within the distribution system. In general, the profiles comprise filters that enable various functions within the distribution system, and may be applied to the iTV applications according to any of a number of bases. The distribution system includes an interface or console adapted to permit a system operator to create the application profiles and establish rules for attaching the profiles to the iTV applications, and an application profile engine configured to automatically validate the iTV applications against the profiles according to those rules.
