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.
Meeting the Challenges of Broadcast Distribution
see In the dynamic, always-on broadcast industry, point-to-multipoint satellite communication is today’s global carrier of choice. It provides instant connectivity between remote or mobile units and the central broadcast hub, and supports Digital Satellite News Gathering (DSNG), studio-to-studio, Direct-to-Home (DTH), digital cinema and more.
NovelSat NS4 is a game-changing 4th generation satellite transmission technology that is well-positioned to meet the needs of today’s evolving broadcast distribution industry. Delivering the fastest data rates – as much as 425Mbps per unit, 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.
The demand for content channels continues to increase as HDTV and 1080p broadcasting move into the mainstream, with 3D and 4K broadcasting entering the mix. Broadcast distribution providers are challenged to cost-effectively obtain the spectrum needed to deliver content. Lack of bandwidth availability and prohibitively high bandwidth costs hinder distribution, and negatively impact 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.
NovelSat satellite transmission solutions, including modems, modulator and demodulators and the NovelSat NS3 waveform offer broadcasters more channels per MHz and higher bandwidth efficiency for existing channels compared with any standard available. NovelSat NS3, the predecessor to Novelsat NS4, has a strong record of field proven success with major live events broadcast in 4K, delivering the most resilient satellite signal on the market.

The Direct-To-Home (DTH) market can be considered to be a more conservative market. While there are frequent technology improvements and new satellite transmission standards available (e.g., DVB-S2, DVB-S2X), these require substantial investment to upgrade consumer headend units. That is why many of the millions of deployed DTH set-top boxes (STBs) still use satellite transmission technologies based on the DVB-S waveform to broadcast more than 30,000 TV channels. At the same time the number of TV channels is constantly growing along with the need for higher quality (HDTV, 3D and UHD).
For that reason, NovelSat offers DVB-S with 5% Roll-Off Factor and DVB-S2 with 5% Roll-Off Factor (ROF) in its NS1000 Satellite Modulator. This upgrade from the DVB-S/S2 standards’ higher typical ROF enables more data capacity (More SD, HD, UHD TV channels) using the same satellite bandwidth without replacing the deployed consumerd STBs.
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.
