SR1 – DVB-S2 Demodulator

Ayecka SR1 is advanced DVB-S2 Demodulator with 240Mbps over a GigE inter face, an IP-over-satellite receiver that gives service providers a strong competitive edge. SR1’s best cost-performance parameters lead the market. With its support of advanced modulation modes at 16 and 32 APSK, SR1 delivers more performance at lower cost and signifi¬cantly reduces long-term operating costs.

SR1’s best cost-performance parameters currently lead the market. With its support of advanced modulation modes at 16 and 32 APSK, ACM, VCM, and Pre-distortion Feedback Channel. SR1 delivers more throughput over the available bandwidth. EUMETCAST, NOAAPORT, MVDDS, IP/SAT and VIDEO/IP/SAT approved, SR1 significantly reduces long-term operating costs.

Satellite service providers can leverage Ayecka SR1 demodulators across multiple applications, including bandwidth augmentation for VSAT networks, satellite unidirectional networks, data-casting, IPTV, and digital TV head-ends.

The use of DVB-S2 technology significantly improves the performance of IP over satellite networks. Ayecka’s SR1 leverages DVB-S2’s advanced features by increasing both the channel capacity and the efficiency of existing transponders to deliver higher bit rate.
