Telelynx introduces a cardless, cost-effective content  encryption system,  called LynxCrypt 100, to meet the requirement of cable operators who prefer to run a basic, simple  encryption system at the beginning to reduce their front-end investmenet. LynxCrypt 100 uses the technology of Addressable Software Trap  (AST), developed   by Telelynx, to encrypt the channels. 
LynxCrypt 100 is designed to be upgradeable to a full scale Conditional Access System (CAS), model LynxCrypt   200, which already has a very successful deployment in numerous digital systems around the world.
LynxCrypt 100 allows operators to automatically shut off the viewing right of subscribers from the headend when subscription expires.
The advanced version of LynxCrypt 100 also includes a practical subscriber management system (SMS)designed for cable/MMDS operators.This SMS supports Stop/Resume authorization as well as tier (package)-based subscription.  A basic billing system and  subscription statistics  are also  included in  the LynxCrypt  100 system. Optional functions such as master-slave STB, pay-per view (PPV), Mosaic program guide, and auto database backup are also available for operators to select.
The set-top box (STB) is programmed in the factory to decode the encryption software  from the  transport stream. With  this scheme,  therefore, any  un-authorized STB will not be able to view any scrambled programs. 
No smart card is needed in the LynxCrypt 100 system, leading to a big saving for the operators. The STB also supports "FTA Block" to disable the output of FTA channels.

Advantages
LynxCrypt 100 offers the following advantages.
*An innovative software - based addressable trap system
*A low-cost solution for operators to encrypt their contents
*Prevent un-authorized viewing of precious channels. A free-to-  air (FTA) STB is not allowed to view any encrypted programs
*The system is scalable and can be used for cable/MMDS   systems of any size, large or small
*Operators can shut off the viewing right of any given STB from the head-end computer
*The system can be upgraded to a full scale, smart-card based conditional access system
*No smart card is needed in the STB to run LynxCrypt 100, leading to a sizable saving for operators
*No smart card reader is needed, a further saving for operators (Smart card reader is an option).
*STB can be upgraded to take smart card reader in the future when running a full scale CAS is required
*Subscriber\'s STB can continuously view authorized scrambled channels even when the CAS/SMS server PC fails or is powered off.
*Supports Master-Slave Set-Top-Box function (option)
*Supports FTA Block and early Reminder of subscription expiration
