HALRTMX-M12-SCR

The NetVX™ platform can now address market segments such as Direct-to-Home (DTH), non-free-to-air DVB-T, and select business-to-business applications with the addition of new DVB scrambling and Conditional Access capabilities enabled by a Simulcrypt interface.

The HALRTMX-M12-SCR can accept unencrypted programs from a variety of sources such as local encoders and network interfaces, including ASI, Gigabit Ethernet or DS3/OC-3/E3/STM1. It interfaces with the Simulcrypt synchronizer (SCS) on the control module to access Control Word (CW) and Conditional Access information (entitlement control messages or ECMs). Each program is encrypted using DVB common scrambling, and ECMs are multiplexed into each stream to provide a DVB-compliant output.

The HALRTMX-M12-SCR — based on the TMX hardware — now runs on a new software and a unique firmware load that turns the TMX into an encryption engine supporting 63 simultaneous programs at a combined rate up to 200 Mb/s. Since the SCR is derived from the TMX, it is known as the HALRTMX-M12-SCR and is configured as such.

In addition to the encryption hardware, the HALRTMX-M12-SCR also contains a hardware random number generator known as the Control Word Generator (CWG) by Simulcrypt. The SCS requests a new Control Word from the CWG on the SCR each Crypto Period (CP).
