An Implementation Of Digital Dbs Encoder With Dvb Scrambler

Koreasat DBS(Digita1 Broadcasting Satellite) system is composed with 3 subsystems such us RSMS (Resources and Subscribers Management System), TSS(Trunsmitter Station Subsystem), and DBS receivers. In order to implement the CAS(Conditi0nal Access System), DBS video/audio program should be scrambled by D VB(Digita1 Video Broadcasting) scrambler. This paper shows how the video/audio encoder should work with other subsystem such as RSMS and MUX(MuUltiplexer). Also, we introduce how to implement the video/audio encoder with DVB scrambler which is to scramble video/audio programs. In addition, it describes how we control program for subscription and pay-per-view channels.
