Ayecka SR1 Advanced DVB-S2 Receiver
The Ayecka SR1 Advanced DVB-S2 Receiver with a GigE interface, an IP-over-satellite receiver, gives service providers a
strong competitive edge. With the SR1, IP satellite service providers now have the bandwidth to increase their user base
or deliver better service to their existing customer base.
SR1’s best cost-performance parameters lead the market. With its support of advanced modulation modes at
16 and 32 APSK, the SR1 delivers more throughput with the same satellite link. By delivering a higher bit rate
using the same satellite bandwidth, the SR1 significantly reduces long-term operating costs.
Satellite service providers can leverage the Ayecka SR1 across multiple applications, including bandwidth
augmentation for VSAT networks, satellite unidirectional networks, data-casting, IPTV, and digital TV head
ends.
Enhanced Features
Focus on Reception – SR1’s unique architecture focuses
on satellite reception and DVB-S2 to IP conversion,
leaving data routing to external routers. The SR1 provides
complete implementation of the DVB-S2 receiver
(including ACM, VCM, multistream and more)
Adaptive/Variable Code Modulation – IP satellite
providers can provide real-time and flexible power and
modulation schemes and packet density to pre-defined
customer groups at various locations, instead of
addressing the lowest common denominator
Support for ACM - Implementation of ACM is based on
availability of return channel (terrestrial or other) and is
compliant with ETSI TS102 441
Dual-carrier Receive Feature – If customer bandwidth
needs require the receipt of two carriers from two
satellites, the SR1 aggregates the bandwidth into a single
delivery
Wire-speed – SR1 handles traffic from the satellite to the
network via dedicated hardware, supporting payload
rates of up to 165 Mbps and eliminating the bottleneck
caused by CPU processing
GigE – Provides gigabit Ethernet as a standard feature
Streaming – Offers video streaming of MPEG transport
over IP output(1)
|
Highly Efficient Hardware – SR1 is a highly specialized
hardware platform supporting different modes of
operation and completely customizable to unique
customer needs, reducing initial capital expenses and
long-term operating costs while eliminating vendor lock
in off-the-shelf with a fixed spec
Generic Stream – SR1 support the new generic stream
IP over DVB-S2 encapsulation, offering superior
performance for IP over satellite delivery, as compared
to the multiprotocol encapsulation (MPE) (1)
Easy Integration – Provides IP or MPEG-TS over
DVB-S2 reception across most network architectures
Channel Encryption – To ensure the highest levels of
service security, SR1 supports BISS encryption using
local or Internet-based key management. Channel
encryption is available as an option(1)
Flexible Management Interface - Provides an
independent 100baseT management interface
supporting CLI, Telnet, and SNMP
Highly Competitive Pricing – Ayecka's SR1 offers
advanced technology at more than 50% less than other
devices on the market

SR1 Highlights
- Professional DVB-S2 receiver supporting ACM, VCM, 16/32 APSK
- Dual carrier (2) receiver for 8PSK CCM, single for ACM
- GigE interface to support full DVB-S2 transponder
- Supports MPE and GS(1)
- Supports MPEG over IP – Pro-MPEG and RFC2250(1)
- Receives MPEG-TS and encapsulates over IP output
- Independent local IP interface for management
SR1 supports two modes of operations:
- Data mode - SR1 receives the DVB-S2 signal and decapsulates the IP information from the MPEG transport stream
or baseband frames. IP packets, unicast or multicast, are forwarded to the default router
- Transport stream forwarding - SR1 receives the DVB-S2 signal, and MPEG-TS packets are encapsulated over IP
and sent out to the network.
SR1 & IP over Satellite with DVB-S2
Using DVB-S2 technology significantly improves the performance of IP over satellite networks. Ayecka's SR1 leverages
DVB-S2’s advanced features by both increasing the channel capacity and the efficiency of existing transponders to
deliver higher bit rates, higher then 100Mbps.
As the SR1 completely supports the DVB-S2 spec, the advanced operation modes offer optimization to operators in both
C-Band (with VCM) and KU-Band (with ACM). For both networks types, the SR1 provides additional improvement with
the migration from IP over transport stream to IP over generic stream. SR1 supports ETSI TS102 441 implementation of
ACM communication for smooth integration with any DVB-S2 ACM head end.
