Work Microwave's DVB-S2 Modem SK-DV

Work Microwave, a leading European manufacturer of advanced satellite communications, today announced a new combined data and video modem, the DVB-S2 Modem SK-DV. Utilizing DaVid technology, the device offers simultaneous transportation of data (network connection) and live broadcasting (video content) over a single satellite carrier.
The DaVid technology works by aggregating multiple MPEG transport streams and IP data into a single baseband stream, called multistream, which is then inserted into a broadcast modulator. The single carrier signal is transmitted via satellite by the modulator and then received by multiple receivers that separate and extract specific content parts based on their DVB-S2 Input Stream Identifier (ISI). The DaVid technology configures all DVB-S2 baseband parameters independently for each stream, providing users with the flexibility to choose the number of streams that need to be processed.
The combined modem includes several features and capabilities designed to provide users with maximum bandwidth efficiency and data throughput at all times. The DVB-S2 Modem SK-DV uses Generic Stream Encapsulation according to TS 102 606, which ensures the device is compatible with products from other providers compliant to the DVB-S2 standard and allows users to easily incorporate the modem into existing operations. Additionally, advanced modulation up to 32APSK offers the most efficient satellite communication for dedicated links, enabling broadcasters to deliver reliable, flawless transport.
Multichannel ACM functionality (OptiACM) compensates for disturbances in the satellite link due to physical conditions — such as humidity and atmospheric precipitation — through real-time adaptation of transmission parameters according to link conditions, improving data throughput in all usage cases and under all environmental conditions. Additionally, the DVB-S2 Modem SK-DV optimizes the amount of usable bandwidth through a traffic shaping capability that controls the volume of traffic being sent over satellite and determines minimum/maximum data rates for each content type. Traffic is differentiated into groups and prioritized with respect to a number of configurable parameters.
Built on a cross-layer system design that applies interlayer communication exchange across the protocol stack, the DVB-S2 Modem SK-DV operates at an efficient data rate of up to 160Mbps, supporting high-speed data transmission so broadcasters can deliver live high-definition video content over a satellite link — in addition to Internet file transfer.
"As the broadcasting and IT worlds converge, the DVB-S2 Modem SK-DV brings the power of IP to broadcasting by enabling broadcasters to deliver live video, IP data, or both simultaneously," said Joerg Rockstroh, senior R&D Engineer, WORK Microwave. "By using one device to manage ASI and IP inputs, broadcasters now have the ability to support hybrid infrastructures while optimizing bandwidth, boosting data-transport efficiency, and significantly reducing operating expenses."
