Of SatBroadcasting™ Interest: 2wcom's Product Presence @ CommunicAsia2015

[SatNews] 2wcom supplies professional broadcast products for FM, RDS, DAB, DAB+, DVB-S, DVB-S2 and DVB-T, with complete end-to-end DVB-S/S2 Audio/IP Satellite system solutions including professional encoders, modulators and a highly reliable IRD product range.

2wcom’s position in the market is based on a track record of technical innovation, high quality and outstanding 24/7 support. Formed in 1996 with the buyout of Rohde & Schwarz’s FM/RDS product range, 2wcom has its development and manufacturing headquarters in Germany, with a worldwide network of dealer partners.

“For CommunicAsia 2015, we’ve chosen to show some of our intelligent solutions for bringing future-proof versatility and cost saving to high-performance operation in FM-SFN networks, Audio over IP, and MPX over E1 and IP,”  said Werner Drews, the Managing Director of 2wcom

Products on show at CommunicAsia include...

2wcom's MM01 Audio over IP Codec.

MM01 Audio over IP Contribution/Distribution Solution—2wcom’s MM01 is a new compact multi-role solution for audio over IP contribution and distribution. Targeted primarily at studio-transmitter link applications, MM01 is designed for versatility, providing advanced redundancy capability and monitoring functions, with the ability to integrate into diverse infrastructures. The MM01’s audio synchronization, delivered to microsecond accuracy, also makes it suitable for applications where precise timing is essential, such as SFN FM networks. Offering comprehensive support for today’s most widely-used audio codecs including AAC and eAPTX, the MM01 also supports dual streaming and Pro MPEG FEC—standardized mechanisms for overcoming IP limitations when they occur.
MPX over E1/IP Solution—Delivers CAPEX savings because less equipment is required - no stereo-generator or RDS encoder are needed at the FM-TX sites. The FM-MPX signal can be produced and distributed from one central location (Play-Out Center). The solution also creates cost savings in infrastructure because less space is needed at the transmission sites, and operational savings because less equipment results in less power consumption, less heat dissipation, less in cooling down the sites year by year.
Single Frequency Network System Solution—Timing is a critical requirement for SFN networks because all transmitters broadcast on the same frequency. SFNs can be deployed in digital networks like DVB-T/T2 or for analog FM or AM broadcasting, but the challenge is always the same – ensure accurate synchronization between the transmitters. The solution provides precise accuracy in synchronization of FM cells with automatic adjustment of runtime differences caused by variable packet delays, jitter and satellite anomalies. Distribution can be by E1, IP or satellite, and any one of the feeds can be selected for backup purposes without affecting the synchronization. Adjustment of runtime differences, jitter etc. is automatic.
