With the wide deployment of Internet Protocol (IP) infrastructure and rapid development of digital technologies, Internet Protocol\r\nTelevision (IPTV) has emerged as one of the majormultimedia access techniques. A general IPTV transmission system employs\r\nboth encryption and forward error correction (FEC) to provide the authorized subscriber with a high-quality perceptual experience.\r\nThis two-layer processing, however, complicates the system design in terms of computational cost and management cost. In\r\nthis paper, we propose a novel FEC scheme to ensure the secure and reliable transmission for IPTV multimedia content and services.\r\nThe proposed secure FEC utilizes the characteristics of FEC including the FEC-encoded redundancies and the limitation of\r\nerror correction capacity to protect themultimedia packets against the malicious attacks and data transmission errors/losses. Experimental\r\nresults demonstrate that the proposed scheme obtains similar performance compared with the joint encryption and FEC\r\nscheme.
