DVB-RCS OVERVIEW

• Abbreviation of Digital Video Broadcasting - Return Channel via Satellite
• A second generation VSAT system that dynamically share satellite bandwidth between all the terminals in the system
• A system that provides a pure IP based communication channel from end-to-end
• Suitable for installations where you have one HUB and hundreds or thousands of terminals
• The more terminals in the system – the more re-use of bandwidth - Contention
• Uses standard satellite TV transmission technology to carry IP traffic DVB-S (MPEG2 format)
• Uses a TDMA based return link over the same satellites - RCS
• A number of Quality of Service (QoS) mechanisms are designed into the system – Can prioritise traffic like VoIP
• IP header and IP address recognition
• Fixed, time and volume based bandwidth allocation per terminal
• Can be changed ”on-the-fly” from the HUB
• Dynamic channel encoding ensures better performance in adverse weather conditions – Enables the use of a smaller satellite dish
• Available for Ku-, C-, EHF- and X-band

 


 

       BENEFITS OF DVB-RCS

• Very Cost Efficient - The most cost efficient satellite system available
• VoIP solution can be integrated with existing PSTN Terrestrial Networks (SS7 or ISDN signalling)
• State of the art Commercial Off The Shelf (COTS) technology
• IP-based making the system future proof
• End user hardware is software upgradeable over the air
• Future Military Standard?-Actively adopted by NATO and other European Armed Forces as the replacement/augmentation for VSAT.SatLink have been recommended by DISA.
• Easily extendable-SatLink Gateway can support multiple satellites over multiple frequency bands
• Security-Can provide end-to-end encryption
