Figure 1: MX1 Applications
The decoder supports full transport stream (TS) decryption and is compatible with all
conditional access (CA) modules. Depending on the hardware configuration, the
decoder can also provide embedded CA.
Two slots for Conditional Access Modules (CAM) are provided in the front panel to
enable decryption of received signals and transmission of the signals in the clear to
customers. Depending on the hardware configuration, additional slots are provided in
the rear for the insertion of smart cards (SC) used for the embedded decryption
function.
Other applications of the decoder include the following:
 Program Identification (PID) filtering and retransmission

Digital Turnaround (DTA) and video monitoring
 Control and monitoring through IP.
In remote mode, all decoder functions can be operated remotely from a PC under
MS-WINDOWS through the IP interface.
In addition to an RS232 or RS422 communication port, the MX1 can provide a General
Purpose Interface (GPI) via a 9-pin D-type connector that allows dry contact alarms.
The GPI depends on the hardware configuration.
In local mode, all decoder functions can be operated through a two-line LCD window
and six buttons on the front panel.
