Control of access to video content is achieved by filtering information identifying the available video content according to one or more applicable profiles and then delivering to an authorized user only the filtered results for the information in a form such as an electronic program guide. In this way the filtered results in the exemplary electronic program guide represent only the content items that meet the profile criteria. Content information, which fails to meet the filtering criteria, can be blocked or scrambled or deleted from the exemplary electronic program guide as a further constraint prior to delivery of the filtered set of information to the authorized user. |
