PayTV model description
The PayTV model is a full broadcast model where the data only flow from the Service
Provider to the users. All users receive all data transmitted, but according to his associated
access conditions, a particular user is allowed or not to have access to the content. This is
performed by means of a conditional access system residing in a smart card inserted in the
decoder. Actual descrambling of the content (i.e. deciphering of the video stream) is done in
the decoder.
