Available to third party manufacturers under OEM agreement, the high performance NTC/7044 is the best solution for the demodulation of DVB-S/S2 carriers in IRDs, IP receivers, and Mobile or Digital Terrestrial TV transceivers. In its default configuration the demodulator board is capable of demodulating an MPEG2 transport stream in DVB-S, DVB-DSNG and DVB-S2. The Multistream, VCM or ACM modes of DVB-S2 are also supported.

The NTC/7044 has a dual L-band input (950-2150 MHz). The active input is selectable and can provide DC power and frequency band selection signals compatible with most professional and commercial LNBs. In DVB-S or DVB-DSNG, the demodulator board delivers an MPEG transport stream on a parallel output. In DVB-S2, the demodulator board can output the Base Band Frame signal, a transport stream or a generic stream. If the demodulated carrier is a Multistream signal, the NTC/7044 can filter and output one of the transport or generic streams, and the ISSY (Input Stream Synchroniser) mechanism defined in the DVB-S2 standard can be activated to recover the initial data rate.

To protect the satellite transmission in DVB-S2 mode, the AES decryption option can be activated. AES encryption allows the transmission of DVB-S2 streams with a high security level. The AES encryption mechanism can work in two different modes. In the first global protection mode all different DVB-S2 streams are encrypted with the same content key. The second mode for protection per stream encrypts up to four DVB-S2 streams with a different content key. To compensate for linear distortion in the transmission channel, the NTC/7044 is equipped with an adaptive equalizer.

The demodulator board can be controlled via an asynchronous serial link with a comprehensive range of monitoring and control functions.

Clean Channel Technology® is available on the demodulator. Clean Channel Technology further improves satellite efficiency by up to 15% compared to the current DVB-S2 standard. Clean Channel Technology is available as a software upgrade.
