Thor DVB-S2 modulators are built to the highest standards and fully comply with the second generation standard for satellite modulation of digital video broadcast streams. This platform is able to ingest a single program or multi program transport stream in either ASI or IP (MPEG-TS UDP) format. The chassis modulates the entire transport stream, along with any secondary programs and closed caption PIDs. For the highest reliability applications, an additional 3 ASI program stream inputs are provided and constantly monitored for stream integrity. With all four inputs constantly monitored for faults in the bit stream; the modulator can intelligently switch from one input to another the second a fault is detected. This allows a constant error free output to the DVB-S2 carrier. The processor recovers quickly enough to prevent even a single dropped frame in the output stream. Other options include redundant power supplies.
In addition to reliability and redundant inputs; Thor satellite modulators provide many other useful features to extend the functionality of the platform. For content protection and encryption, the modulator supports BISS program stream scrambling for protecting your content. This prevents unauthorized access to the content by making the RF channel unreadable without a pre shared BISS decryption key. This convenient content protection is used worldwide for affiliate links and SNG uplinks. Other features include 10 MHz synchronization on both 10 MHz reference inputs and outputs. For stability, the system uses a high reliability crystal oscillator that is fully temperature controlled. This provides high reliability frequency locking down to 0.1 ppm stability.
Carrier grade DVB-S and DVB-S2 satellite modulator for 3x redundant hot inputs for highest reliability and fall over protection. Provides latest generation support for 16APSK and 32APSK modulation constellations.
