DVB-CSA for DVB-IPTV (Common Scrambling Algorithm)
Content Scrambling Algorithms for DVB-IPTV Services using MPEG2 Transport Streams
The present document provides specifications for the scrambling of MPEG2-Transport Stream based content conveyed by DVB-IPTV services for both live media broadcast and content on demand services. In addition, it provides information regarding the relevant signalling that enables conditional access systems or digital rights management systems to protect their content using the scrambling methods described in the present document.
The scrambling of IPTV content not contained in MPEG2 Transport Stream is out of scope of the present document.
