A method for distributing geographical restriction data in an internet protocol television (IPTV) system is disclosed. The method includes accepting at an IPTV server, a request from an IPTV client for the geographical restriction data related to geographically restricted video data, determining at the server, a plurality of geographic restriction zones for the geographically restricted video data and sending from the server to the client a message containing the restriction data related to at least one of the restriction zones.
