What is DVB simulcrypt?
The DVB Simulcrypt specification allows two or more CA systems to be used by the same receiver population, particularly important when a pay TV provider wants to switch to another CA system. The Simulcrypt approach is based on DVB’s toolbox of Common Scrambling Algorithms (CSA) combined with the necessary signalling.
What is the simulcrypt approach?
The Simulcrypt approach is based on DVB’s toolbox of Common Scrambling Algorithms (CSA) combined with the necessary signalling. There is an impressive ecosystem of CA solutions providers whose products are based on DVB specifications.
What is Common Scrambling Algorithm (CSA)?
The Common Scrambling Algorithm (CSA) is the encryption algorithm used for encrypting video streams in DVB television services. CSA is comprised of the Common Descrambling System and Scrambling Technology.
What is DVB-CI and how does it work?
The DVB-CI specification describes the interface between a Conditional Access Module (CAM) and the host, which is typically a TV set. All the conditional access functionality is provided by the CAM whereas the host provides the necessary tuning functionality and presents audio and video.
