Multistream DVB-S2 Modulator

Overview

The ViaSat 96100 SkyPHY MSM is a DVB-S2 customizable forward link multistream modulator core. Combing up to 8 input transport streams, it is an aggregator on a chip.

It enables DVB-S2 transmissions in CCM (Constant Coding and Modulation) and VCM (Variable Coding and Modulation) modes. Each stream can be independently modulated using VCM. Modulators with SkyPHY MSM optimize satellite bandwidth by aggregating multiple transport streams on one satellite carrier.

The core has been successfully tested and has been employed on multiple variants of DVB-S2 transmitter and transceiver products.

The multistream modulator features can be turned on, off, or modified for specific applications. The design allows easy reconfiguration for specific application requirements.

DVB-S2 compliance, flexible-architecture, and proven hardware make the SkyPHY multistream modulator core an attractive forward link core for advanced communications.
