SR1 Block Diagram

SR1 receives the DVB-S2 signal and De-capsulates the IP information, either form the MPEG transport stream or baseband frames. IP packets are forwarded to the default router. Multicast traffic can be forwarded directly to the network. MPEG-TS packets are encapsulated over IP and sent to the network


IP over satellite with DVB-S2

Delivering IP traffic over satellite is in use for many years. The emerging new standard, DVB-S2, provides tools to improve the performance of IP over satellite networks.

The advanced Forward error Correction used by DVB-S2 allows an increase in the channel capacity, and the use of existing transponders to bit rates higher then 100Mbps.

Modulation scheme became more sophisticated with DVB-S2. The support for VCM and ACM give operators tools to further optimize the use of the space segment.

VCM allows optimization of C-Band links by assigning different FEC to different terminals on different contours. ACM optimize Ku-band links by setting dynamically the MODCO per terminal.

Encapsulation of IP over the MPEG-TS was optimized by the introduction of Generic Streams that provides even higher efficiency when using DVB-S2.


The SR1

Ayecka SR1 is an advanced DVB-S2 receiver with a GigE forwarder. 

The SR1 designed with satellite reception in focus, leaving routing to be handled by external device. 

SR1 implementation is based on advanced engineering methods that eliminate the bottleneck caused by CPU load. The SR1 support payload rates of up to 120Mbps 

SR1 supports DVB-S2 VCM and ACM. Implementation of ACM is based on availability of return channel (terrestrial or other). The SR1 can be used as receiver for MPEG-TS and encapsulate them over IP output 

Ayecka proprietary encryption (using internet connectivity to head end) is available as an optional package. 

SR1 provides independent 100baseT management interface. Management interface support CLI, WEB and SNMP.
