New York, NY, October 12, 2007 - Nucomm, Inc., a leading provider of digital and analog microwave systems for the broadcast industry, common carrier, cable, government, military and international marketplace, showcased its new Messenger IP Encapsulator/Decapsulator at HD Word 2007. The Nucomm Messenger system enables broadband IP connectivity between an ENG truck or OB Van and the broadcast studio. Designed to support today‘s emerging, distributed news editing workflows, the Nucomm Messenger makes it easier for television news stories to be edited in the field and delivered to the studio over alternative networks.


With an IP network in place, other applications, such as remote queuing and remote truck control, can also run between the studio and the ENG vehicle.


The Nucomm Messenger can be used in trickle or broadband mode. In trickle mode, live video and IP traffic are sent simultaneously; the live video reduces the IP traffic to a rate in the range of 100 kbps to 1 Mbps. The Messenger does this transfer by replacing null packets with IP packets.


In the broadband mode, nearly the entire link is dedicated to IP traffic. The user either turns off the MPEG encoder or removes the video source to the encoder, creating a transport stream nearly full of null packets. In this mode, the Encapsulator responds automatically to the changing network conditions.


A complete Nucomm Messenger system consists of a 1 RU Encapsulator and a 1 RU Decapsulator. IP data from the news gathering vehicle to the studio flows through the existing ENG / OB infrastructure. The outbound IP traffic enters the Messenger IP Encapsulator. The IP traffic is encapsulated into the MPEG stream from the MPEG encoder in the ENG transmitter. The resulting ASI stream, containing the IP data and video data, returns to the ENG microwave transmitter, where it is transmitted back to the studio.


The Nucomm Messenger is one in a series of products introduced by Nucomm to support the migration of television broadcasters to digital electronic news production. For more information about the Nucomm Messenger, visit www.nucomm.com.
