Abstract
A method of restricting access to content delivered via a video distribution network is disclosed and includes receiving a control stream at a service delivery platform. The control stream is related to media content delivered via a video distribution network. The method also includes parsing the control stream and determining, from the parsed control stream, at least one geographical area in which access to programming associated with the video content channel is to be restricted. The method also includes automatically scheduling a conditional access event associated with the media content at least one video head-end of the video distribution network, the at least one video head-end serving the at least one geographical area. In a particular embodiment, the video distribution network can be an Internet Protocol Television (IPTV) network.
