GeckoFlex 8972PX Protection Switch

The 8972PX is a full-time signal protection switch. It is a highly robust primary/secondary changeover switch for HD-SDI, SD-SDI, or ASI signals. It can be controlled by autonomous switching to a backup signal using in-built detection of signal failure, switched by manual controls, or driven by an external GPI system to switch on command.

The 8972PX fulfils the basic requirement of any protection system by not adding failure modes to the existing signal path. In the event of a power failure, or even if the front control board is completely removed, the Program Output signal will continue to pass from the previously selected input as a fail-safe relay path will latch the selected signal to the output. In driven mode it can be configured by GPI or Ethernet.

All parameters can be configured via the web browser interface and main parameters via the Newton Control Panel. NetConfig and CommandCenter are supported respectively for remote configuration and product health monitoring. Asserting GPI control or other manual controls will disable autonomous control.

  • Two-input robust failure-proof changeover switch
  • Third alternate input, available for switching, non relay-protected
  • Supports HD-SDI, SD-SDI, and DVB ASI with auto-sensing capability
  • Will maintain signal path in the event of power failure or when the front card is removed
  • Eight outputs, including:
    • One main relay-protected output with passive bypass path
    • One electronic output follows main
    • Three output pairs can be set to follow main or backup or can be switched to primary, secondary or alternate inputs
  • Line switching in driven switch mode (HD/SD-SDI syncronous input signals)
  • External control via GPI or Ethernet
  • Autonomous control by:
    • Signal (carrier) loss detection
    • Incorrect signal format
    • EDH/CRC error (selectable threshold)
    • DVB-ASI PID loss
    • DVB-ASI packet loss
  • GeckoFlex dual-slot rear board
  • Asserting external control of the board automatically turns off autonomous control
  • Select between primary, secondary, and alternate inputs paths
  • Switch to alternate input (i.e., apology/technical difficulties slide) when primary and secondary inputs are both failing

Hillsboro, Ore., November 25, 2013 — Brazil's Canção Nova, a non-profit Catholic Community located in Cachoeira Paulista in the state of São Paulo, is upgrading its broadcast infrastructure with a range of Grass Valley® solutions including five Maestro™ branding and master control systems, five Concerto™ 64x64 routing switchers, five GeckoFlex™ signal processing systems, and six K2 Summit® servers for optimized live event workflows. The system will be live in November and span five locations.
Hillsboro, Ore., November 12, 2013 — Bank TV, a satellite broadcaster in the Ukraine, has launched a complete, end-to-end high definition (HD) news production solution from Grass Valley® to facilitate the smooth delivery of its 24/7programming. At the core of the broadcaster's new structure is GV STRATUS® nonlinear media production tools for enhanced production and a streamlined workflow. GV STRATUS is being used in tandem with EDIUS® multiformat nonlinear editing software and GV Edge™ Integrated Playout System with K2 Edge™ playout nodes for 24/7 playout. This deal with Bank TV builds upon the recent momentum generated by Grass Valley in the Ukrainian broadcast market as well as traction gained by GV STRATUS in the EMEA region.
