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.

14. The method of claim 1, wherein one or more of the iTV application profiles specify a fetch frequency for the iTV application distribution system to retrieve the iTV application.

15. The method of claim 1, wherein one or more of the iTV application profiles specify a target destination from which the iTV application distribution system can retrieve the iTV application.

16. The method of claim 1, wherein the validating includes performing one or more of the following:

(i) automated validation of a relationship with an iTV application provider;

(ii) automated validation to ensure the iTV application is correctly formed;

(iii) automated validation of asset reference integrity within the iTV application;

(iv) automated formatting of the iTV application;

(v) automated bandwidth allocation verification for the iTV application;

(vi) automated validation to ensure that the iTV application is only able to access permitted set-top box functions;

(vii) automated validation to ensure that the iTV application has arrived for distribution in accordance with a previously established distribution schedule;

(viii) automated verification of the iTV application'"'"'s make up;

(ix) automated validation of restrictions on the iTV application'"'"'s ability to invoke other applications;

or (x) automated validation of the iTV application'"'"'s use of one or more settings for iTV services provided globally by an iTV application service provider to multiple iTV application providers.

17. A method, comprising:

receiving, in an interactive television (iTV) automation system, an iTV application defined by a package including an iTV application layout and an iTV application data set for populating the iTV application layout;

associating the iTV application with a plurality of iTV application profiles that includes a first profile enumerating rules for validating the iTV application layout and a second profile enumerating rules for validating the iTV application data set;

automatically validating the iTV application layout against the rules for validating the iTV application layout;

automatically validating the iTV application data set against the rules for validating the iTV application data set; and

conditioned upon at least both the iTV application layout and the iTV application data set being validated, controlling delivery of the iTV application layout and the iTV application data set to iTV application clients via an iTV application distribution system such that the iTV application layout is delivered with less frequency than the iTV application data set.

18. The method of claim 17, wherein the iTV application is received in response to a scheduled fetch thereof according to a schedule specified by at least one of the plurality of iTV application profiles.
