Comtech EF Data understands your need to optimize satellite communication links. As a long-time supplier of modulator, demodulator and frequency conversion equipment to broadcasters, our products are installed in more than 160 countries. Our solutions encompass contribution and distribution for various broadcast applications. We are compliant with key Digital Video Broadcasting standards, such as DVB-S2 and DVB-S, and interoperate with major satellite service providers and key encoder/decoder vendors.

Modems, Modulators & Demodulators
We offer the widest range of bandwidth efficient modems available in the satellite industry. Based on technologically advanced components and innovative design, our modems include application software to provide superior performance and features. Available with numerous configurations and options, our family of modems offers the functionality required for broadcast and satellite news gathering communications. Our technologies are compatible with flyaways and uplink trucks’ portable antennas, and support both contribution and distribution:

The CDM-710 Broadcast Satellite Modem is based on the transmission standard, DVB-S2, and is ideally suited for High Definition Television (HDTV) contribution. DVB-S2 extends the scope of possible applications by combining functionality of previous standards developed for Direct To Home (DTH) and professional environments. The broad range of modulation and coding formats of DVB-S2 enable link performance optimization - delivering on average 30% greater throughput when compared to DVB-S services. Users can tailor a link for the available bandwidth and power. Whether a link is for Direct To Home (DTH) or Digital Satellite News Gathering (DSNG), Contribution or Distribution, there is a format available to suit each application. The ASI or optional Gigabit Ethernet interface for the CDM-710 support both legacy and green field video production builds. And, beyond the DVB-S2 support, the CDM-710 offers spectral roll-off functionality that delivers additional satellite transponder cost savings.

Our CDM-570/L Satellite Modems, CDD-564/L Quad Demodulators and CDD-562L Dual Demodulator are IP-enabled and take bandwidth optimization to a higher level. Available features such as Payload Compression, Header Compression and Quality of Service (QoS) enable significant bandwidth savings, improve transmission quality and increase control of bandwidth provisioning. And, these products are compatible with the Vipersat Network Products for bandwidth and capacity management.

With the flexibility and features provided by our modems, modulators and demodulators, you can:

RF Products
Comtech EF Data also offers an extensive line of RF products – converters, amplifiers, transceivers and terminals – for a range of configurations, which are deployed globally. Compact and rugged platforms, field replaceable power supplies, redundancy and a variety of frequencies are just some of the options available in our RF products.

Encapsulator & Receivers
The Encapsulator and Receiver products are IP-based and support Digital Video Broadcasting standards for DVB-S & DVB-S2 The products optimize end-to-end solutions for stand-alone and overlay broadband IP networks. A range of interfaces, redundancy options and IP-based management are provided to accommodate diverse network configurations. The Encapsulator and Receiver products support video and IP-based content contribution and distribution. Most commonly supporting broadcast communications, ideal applications include IPTV, digital cinema, digital signage, IP multicasting, file delivery, streaming audio and video, and multicast file transfers.

Comtech's DVB-S2 Solution
Leveraging the bandwidth efficiencies of DVB-S2, the combined solution of our modems, modulators, demodulators, IP encapsulators and receivers can increase throughput by up to 30% compared to DVB-S. Now, operating expenses to deliver your IP-based broadcast connectivity can be significantly reduced.

Bandwidth & Capacity Management
Our feature rich and cost-effective bandwidth and capacity management solution integrates with our IP-enabled satellite modems. It is based on dynamically managed Single Carrier Per Channel (SCPC) and automatic application switching technologies.

A complete suite of IP-based transmission services including broadcast video, Internet/intranet, e-mail, facsimile, file transfer, communications/IFB and Voice over IP (VoIP) are provided using our unique approach to satellite bandwidth management.

Network Entry – Instant deployment and tear down in highly mobile environments are greatly simplified with Comtech solutions.

Remote Office – Field personnel can utilize VoIP phones for connectivity to your company’s telephone system, accessing e-mail and transmitting file transfers for pre-production video via our real-time, interactive two-way connectivity between remote locations and your broadcast center or hub.

Dynamic Bandwidth Allocation – when it is broadcast time, the dynamic SCPC (dSCPC) technology automatically resizes the SCPC carrier from the truck or flyaway, based on the application or data load.

Transmission in Native Broadcast Formats – A network powered with VMS also provides the control of our non-IP modems

Point-to-Multipoint Transmission – feeds or other high priority data can be sent from the remote to multiple locations simultaneously utilizing SCPC carriers in the same bandwidth pool.
