In the dynamic, always-on broadcast industry, point-to-multipoint satellite communication is today's global carrier of choice, providing instant connectivity between remote or mobile units and central broadcast locations, and supporting Digital Satellite News Gathering (DSNG), studio-to-studio, sporting event coverage, entertainment, digital cinema, digital signage and more.
NovelSat NS3™, 3rd generation satellite transmission technology is a game-changer, well-positioned to meet the needs of today's changing broadcast distribution industry. Delivering the fastest data rates – as much as 425Mbps per unit, NovelSat NS3 supports both Video (ASI) and video over IP, delivers the widest pipe and the most compelling ROI available. That's why some of the world's largest broadcast contribution and distribution providers have replaced their satellite transmission equipment based on DVB- S and DVB-S2 with NovelSat modems, modulators and demodulators equipped with NovelSat NS3.
NovelSat FreeBand lets broadcasters re-use the same bandwidth, transmitting at the same frequency, both to send video to the point to multipoint distribution network and to receive video or data from DSNGs, flyaways, remote studios and other remote data and video contribution units. In essence, broadcasters get free satellite bandwidth for video contribution.

As the number of channels increases exponentially, HDTV and 1080p broadcasting move into the mainstream, with 3D and J4K broadcasting entering the mainstream, broadcast distribution providers are challenged to cost-effectively obtain the spectrum needed to deliver content. Lack of bandwidth availability and prohibitively high bandwidth costs are hindering distribution, and negatively impacting the bottom line.
Beyond the economic challenges of satellite broadcasting, environmental factors aggravate efforts to deliver the high-quality video that customers expect. These factors include weather fluctuation resilience, interference and jamming resilience, phase noise resilience and optimal functioning under saturation.
Bandwidth Efficiency
Solutions based on NovelSat NS3 typically deliver 40% to 60% higher bitrate availability per MHz, reducing the overall amount of bandwidth required. Located in the distribution hub and receive sites, in front of the IRD, NovelSat NS3-based modulators and demodulators enable the addition of more channels at higher resolutions, without adding more satellite capacity. Moreover, by enabling work with a single carrier over a 84MHz transponder, NovelSat NS3-based solutions push throughput gains even further.
Resilience
NovelSat NS3 technology, embedded in NovelSat modems, modulators and demodulators, uses advanced algorithms to minimize and in some cases eliminate the effects of weather fluctuations, interference, phase noise, saturation and the increasing menace of intentional jamming which can reduce efficiency, and even block transmission completely.
Flexibility
NovelSat NS3-based solutions are also backward compatible with DVB-S, DVB-S2, DVB-SNG and other standards and forward compatible with new technologies such as HTS. So, broadcasters can take advantage of the speed, resilience and flexibility of NovelSat satellite transmission equipment without expensive forklift upgrades.
Security
In Full-Duplex communication facilitated by NovelSat DUET, very low SNR signals from remote terminals links are treated as noise by any other modem and will not be intercepted. For applications such as FreeBand, when NovelSat NS3 is used, signals can be transmitted at SNR as low as ‑3dB. At such low SNRs, most modems cannot even lock-on to the signal.
