New HD and SMPTE 310M Bypass Protection Switches for Broadcast and Satellite

Grass Valley, CA – 12 April 2008

Ensemble Designs today announced that it will show two new bypass protection switches for its Avenue™ modular signal integration system. The 7455 and 4450 protection switches analyze the health of critical digital video paths and switch to a backup source when needed. The products can be seen at Ensemble Designs’ booth #SU2326 at the National Association of Broadcasters (NAB) convention held April 14-17 in Las Vegas.

“Broadcasters and satellite providers need to be on air 99.999% of the time and these new protection switches will ensure that goal is attainable, said Mondae Hott, Director of Sales at Ensemble Designs. “These switches handle every type of video signal, from HD to SMPTE 310M.”

The 7455 module is a fail-safe, bypass protection switch for critical digital paths. When a fault is detected in the primary input, and the secondary input is verified as good, the switch will activate, causing the secondary input to be switched to the module’s output. The 7455 includes a passive, fail-safe path that ensures there is an output even in the event of a total power failure. The 7455 supports SD SDI, HD SDI, SMPTE 310M and DVB-ASI signals. Different types of signal testing can be enabled for the type of input that is present.

The health of a high definition or standard definition video signal is determined by monitoring crucial parameters in orde rof increasing complexity; Timing Reference Signal (TRS), or a persistent loss of digital sync is tested first. Black, Embedded Audio and Freeze are also evaluated. Each test can be configured by the user.

The health of an ASI or 310 signal is determined by monitoringdigital clock lock, packet presence, and PID presence. The user can configure tests to define the minimum number of video packets and audio packets expected per second in a given service.

All Avenue modules can be accessed via ethernet with Avenue Logo software, Avenue PC Software, or SNMP protocols.
