Abstract
The present invention includes a method of selectively delivering programming to a viewer station on an interactive television or televideo (IT) system. Determinations as to whether programming is to be delivered are based upon the content or service level of the programming. With reference to content-based delivery of programming, the IT system identifies predetermined characteristics of the available programming. Each viewer at a selected viewer station is assigned a personal programming service level. The personal programming service level of each viewer is related to the particular characteristics and distinguishes appropriate and inappropriate programming for the viewer. The IT system compares the predetermined characteristics of the programming available at a time with the appropriate programming service level. The IT system delivers to the viewer station the available programming with predetermined characteristics that conform to the appropriate viewer service level.
