Product Information

DigiCAP DMB Scrambler

DigiCAP provides DMB Scrambler which is Stand-Alone Scrambler defined in DAB CA standard. DigiCAP DMB
Scrambler is a product for encrypting digital broadcasting content (Video/Audio/Data) to protect and manage the
interest of DMB service providers as well as the rights of consumers.

DigiCAP DMB Scrambler scrambles/encrypts broadcasting contents received from encoder. On processing, it
receives ECM (Entitlement Control Message) and EMM (Entitlement Management Message) from CAS (Conditional
Access System) and provides support in transmitting them with broadcasting content. DigiCAP Scrambler
includes function of SCS (SimulCrypt Synchronizer), CWG (CW Generator) and Scrambler that defined as Headend
components in DVB SimulCrypt standard. It provides part of Mux function for the integration between CAS
and EMMG.

Main Features

Easy portability which enables to support multi CAS in compliance with SimulCrypt standard.

MPEG-2 TS Scrambler	MPEG-2 TS Packet Level Scrambling & Reed-Solomon (204, 188) Coding support Factum Encapsulation Protocol(FEP) support
SubCh CA/ MOT CA Scrambler	Factum Encapsulation Protocol(FEP) support

Processing overhead reduction of device descrambling with full and partial scrambling
- Full scrambling that encrypts all of individual MPEG-2 TS stream and partial scrambling function that transmits partially scrambled TS of MPEG-2 TS stream
- Partial scrambling helps to reduce processing overhead of descrambling by setting up the scrambling range from 1 to 50% by operators
Provides Bypass Mode and CA Mode Transition function
Enables to set up broadcast schedule through Scrambling Control Group (SCG) on CA Mode
- Broadcast schedule based on specific period of time or specific group of people, it could be on hourly, daily, weekly basis
Remote configuration & monitoring through System Configuration Manager GUI Program (Windows)

System Architecture

Main Function
There are 3 options in DigiCAP DRM Scrambler:
MPEG-2 TS Scrambler, Sub-channel CA Scrambler, MOT CA Scrambler

Module	Description
MPEG-2 TS Scrambler	Encrypts broadcasting contents which are transmitted in MPEG-2 TS Packet form ECM and EMM are transmitted together with MPEG-2 TS Stream
Sub-channel CA Scrambler	Sub-channel frame unit encryption Provides CA Mode Scheduling supported by MPEG-2 TS Scrambler Encrypts all data packets or MPEG-2 TS packets in Sub-channel
MOT CA Scrambler	Encrypts partial or full MOT object sent to MOT Directory Mode Provides socket-based protocol in order to send MOT data to scrambler For the integration convenience between MOT CA Scrambler and data encoder, Windows COM library that implemented socket-based protocol is provided to data encoder
