WORK Microwave To Showcase At IBC

At this year's IBC show in Amsterdam, German firm WORK Microwave has announced it will showcase its portfolio of DVB-S2 modems, modulators, and demodulators.
The company will be pushing its new video ACM system, which combines WORK Microwave's DVB-S2 Modem SK-DV with Adtec Digital's EN-91 MPEG-4 HD ultra-low delay encoder.
"In addition to enabling continuous communication between the two devices via SNMP, the integration of the modem and encoder into one environment simplifies the setup and monitoring of parameters and options influencing bandwidth and link allocation," a statement from the company said.
Leveraging DaVid technology, the SK-DV modem concurrently transports up to six MPEG transport streams 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.
WORK Microwave's multichannel ACM functionality reduces the margin traditionally required for rain fade. Satellite link performance is optimised in real time, balancing efficiency and availability as link conditions change due to adverse weather conditions.
Satellite capacity is further optimised via transport stream null packet deletion and re-insertion. The bandwidth saved from removing the null packets from the transport streams can be reused for IP data.
At IBC2013, WORK Microwave will also demonstrate improvements to its fixed frequency block converters.
New enhancements include Ka-band support for both uplink and downlink services.
The Ka-band uplink uses frequencies between 25GHz and 32GHz while the downlink uses frequencies between 18GHz and 23GHz. A new synthesizer allows the frequency converters to deliver Ka-band signals with phase noise at a level that exceeds the respected industry standard according to Intelsat Phase Noise Specification, IESS-308/309.
