MediaGuard is a conditional access system for digital television developed by SECA (Société Européenne de Contrôle d'Accès; renamed to Canal+ Technologies SA) (CEO François Carayol), a subsidiary of Canal+ Group, sold to Thomson (CEO Thierry Breton).
Manufacturers which incorporate MediaGuard into their equipment are notably Hitachi, Ltd., Humax, JVC, Kenwood Electronics, Nokia, Pace Micro Technology, Philips, Pioneer Corporation, Sagem, Samsung Electronics, Sony Corporation, Strong, Thomson, and Toshiba.
The original MediaGuard system has been broken by the end of the 1990s, allegedly by rival NDS Group, which resulted in new cards being distributed to customers in 2002.
