[SatNews] The new improvements, operators can optimize satellite bandwidth, improve signal quality, and reduce operating expenses.
WORK Microwave announced it will be exhibiting at the NAB Show this year. At the booth, the company will demonstrate significant enhancements to its DVB-S2 Broadcast Modulator, Video ACM System, and Fifth-Generation Frequency Converter Series. Leveraging the new improvements, operators can optimize satellite bandwidth, improve signal quality, and reduce operating expenses.
WORK Microwave platforms span a wide range of applications within the broadcast, satellite, and telco markets, including SNG, local cable distribution, direct-to-home, IP trunking and backhaul, teleport, remote location, and more.
DVB-S2 Broadcast Modulator
Powered by a combination of video and IP technologies, WORK Microwave's DVB-S2 Broadcast Modulator provides operators with the ideal solution for IP network links and TV contribution. Through an advanced feature set, the modulators help operators get the most out of expensive satellite bandwidth, optimize data transport, and dramatically improve satellite signal quality. Innovative features include DVB-S2 multistream, TSoIP, wideband (up to 80Mbaud), and carrier ID. In addition, the DVB-S2 Broadcast Modulator platform supports next-generation DVB-S2 extensions, providing operators with a future-proof solution.
The DVB-S2 Broadcast Modulator's most recent improvement — carrier ID support — defines the modulation, channel coding, and signaling protocol intended for the identification of the host carrier. This allows operators to eliminate or reduce radio frequency interference between satellite signals to deliver a higher quality of service to customers.
Video ACM System
A key highlight at the NAB Show will be WORK Microwave's Video ACM System, an integrated data/video (DaVid) modem and encoding solution for enhanced video contribution. Combining WORK Microwave's DVB-S2 Modem SK-DV and the EN-91 MPEG-4 HD ultra-low delay encoder from Adtec Digital, Video ACM automatically improves an operator's satellite link budget, enhancing video quality and reducing operational expenses.
The Video ACM solution can transport multiple MPEG transport streams — up to six — and IP data into a DVB-S2 multistream, enabling simultaneous transportation of data (network connection) and live broadcasting (video content) over a single satellite carrier. Multichannel ACM functionality dramatically reduces the margin traditionally required for rain fade, enhancing video quality. Satellite link performance is optimized in real time as link and weather conditions change, resulting in increased link availability and cost savings for satellite operators. Transport stream null packet deletion and re-insertion further optimize satellite capacity, enabling operators to reuse bandwidth for IP data. As the MODCOD changes, WORK Microwave's DVB-S2 Modem SK-DV seamlessly communicates with Adtec Digital's EN-91 encoder and automatically changes the video rate, ensuring the best possible video quality and optimum bandwidth allocation.
During a live, interactive demonstration at the booth, visitors can see interoperability between the DVB-S2 Modem SK-DV and Adtec Digital's EN-91 encoder. The demonstration will highlight the following key features and benefits: reuse of clear sky margin for improved video quality, automatic scaling to the maximum MODCOD for optimal video quality, improved link availability resulting in reduced operational costs, and optimized Ka-band usage for video contribution.
Fixed Frequency Block Converters
At the 2014 NAB Show, WORK Microwave will also demonstrate Ka-band support for uplink and downlink services, superior phase noise, and adjustable slope compensation for its Fixed Frequency Block Converter product line. The new enhancements are designed to optimize the performance and bandwidth of satellite communications links, enabling operators to cost-effectively deliver a superior signal quality.
WORK Microwave's Fixed Frequency Block Converters are based on a new compact, multichannel module design that allows operators to support up to four channels within 19-inch housing, lowering their operational expenses and saving valuable space. Leveraging the converter's unique four-channel design, satellite operators have access to the full capacity of the Ka-band, spanning 27.5MHz to 31GHz (3.5GHz). The Fixed Frequency Block Converter Series is the ideal solution for operators looking to expand their satellite capacity into next-generation spectrums like Ka-band to support high-bandwidth telecommunications and broadcast services.
