Abstract
A system and method implemented in an interactive television system for selectively controlling the verification of interactive television content delivered to a receiver wherein a notification is provided to the receiver to identify content which can be trusted and, when trusted content is delivered to the receiver, verification procedures on the trusted content are inhibited. The notification may be delivered prior to or with the trusted content, and it may be delivered via the same transmission means as the content or by some separate delivery means. The notification may identify the trusted content positively or negatively and may use wildcards in the identification. The trusted content may be identified by its source (e.g., a trusted channel) or by reference to the content itself. The notification may contain an expiration time beyond which is no longer valid. The notification may also contain an identifier and version number so that a subsequent notification having the same identifier and a later version number will supersede the prior notification.
