Bluebell Upgrades BN390 Multiplexer for 4K Transport

Bluebell Opticom has announced upgrades to its BN390 stand-alone interface that supports single-cable 4K UHDTV transport in broadcast studios and outside broadcast (OB) applications.

Among other improvements, Bluebell said the BN390 multiplexer and demultiplexer modules are now capable of converting between all the various formats of 4K UHD (not just 12G-SDI) for both copper and fiber, and they come with a new software interface for remote configuration and signal monitoring.

The improvements come as part of Bluebell's rollout of remote production tools and will be helpful in OB trucks, stadiums, news facilities and event venues, especially for sports.

“The BN390 makes it easier than ever to reconfigure workflow conditions to accommodate changing camera formats while using existing transport hardware and fiber networks for multiplatform broadcasting,” said Paul Felix McCann, managing director, Bluebell Opticom.

The input on the original BN390 solution was fixed to convert four 3G-SDI signals to a single 12G-SDI output. The latest version can handle HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI and can be set for copper or fiber functionality. Because 12G-SDI doesn't travel far over copper, the new BN390 units have optical ports as standard.

The BN390 can be set to configure itself automatically, or technicians can control it manually through an intuitive graphical user interface (GUI). Besides supporting SNMP access, each BN390 unit serves its own web page for management, setup and configuration. An RJ45 port means the module can be connected directly to a laptop or hung on a network.

The latest version maps the existing control software to Bluebell's emerging GUI technology, built for simple hardware control during remote production. The GUI is a powerful, fast interface that controls the input signal format and the output format. It also works as a network monitor that reports signal loss and other error states.
