The DVB-S2X (Digital Video Broadcasting – Satellite – Second Generation Extension) is an optional extension of the DVB-S2 system. Receivers that follow DVB-S2 or DVB-S standards cannot receive DVB-S2X satellite programs.
The brand-new receiver from Koqit Technology is truly remarkable. Firstly, it uses the latest GX6607 chip from Nationalchip. Moreover, it supports DVB-S2X Satellite Receiver TV Set top box. Additionally, it has HEVC H.265 decoding ability. Not only does it have 2Gbits DDR + 64Mbits Flash memory, but it also has an RJ45 network cable interface. Finally, its biggest advantage is the built-in Wifi function.
DVB-S2X mainly targets the core areas of DVB-S2, like digital video broadcasting, interactive service forward links using ACM, digital satellite news gathering, and professional digital links. Moreover, it’s applicable to new areas that need extremely low Carrier-to-Noise Ratio and Carrier-to-Interference Ratio. For example, it can be used for 4K TV services in the Ku/Ka band. It supports HEVC encoding and can bind smaller capacity block segments from two or three DTH transponders to maximize capacity and use statistical multiplexing.
- DVB-S2X can operate under very low Carrier-to-Noise Ratio and Carrier-to-Interference Ratio (down to -10dB). It’s suitable for various markets, such as onboard business jets, maritime, civil aviation Internet access, VSAT terminals in higher frequency bands or tropical areas, and small portable terminals for journalists and professionals.
- It provides high-capacity and efficient transmission modes to meet the needs of professional links with relatively high Carrier-to-Noise Ratio and Carrier-to-Interference Ratio.
Based on the DVB-S2 system architecture, DVB-S2X adds more refined MODCOD steps, sharper roll-off filtering, and multi-transponder binding techniques. It also increases signaling capacity through optional periodic superframe structures, extended PLHEADER signaling schemes, and GSE-Lite signal support.
The emergence of DVB-S2X has brought more possibilities and development opportunities to the satellite communication field. As technology advances, it’s expected to be widely used in fields like high-definition television broadcasting, distance education, and telemedicine. Meanwhile, Koqit will continuously optimize chip solutions and receiver functions, bringing better user experiences.
