Abstract

A method and apparatus for controlling access restrictions for media resource playback may include defining a user-specific content control profile authorizing one or more classes of content to be delivered to a client device, generating a media resource request identifying a first media resource associated with a first class of content and one or more attributes of the content control profile, determining whether the first class of content has been authorized for delivery to the client device based at least in part upon the one or more attributes of the content control profile, and delivering the first media resource to the client device if the first class of content has been authorized for delivery to the client device.
