GeckoFlex 8949MDA-SFR HD/SD Monitoring Distribution Amplifier Fiber-Ready

The 8949MDA-SFR is a monitoring distribution amplifier with SD-SDI monitoring outputs. This board is ideal for low-cost monitoring of HD-SDI signals. The 8949MDA provides four monitoring outputs and four reclocked outputs and can be used to distribute either SD-SDI or HD-SDI making it ideal for mixed format applications or installations where an upgrade is planned. Aspect ratio controls are active on the downscaled outputs with an HD input signal.

With its fiber-ready architecture the 8949MDA can be configured to support up to two fiber connections in addition to its eight coax outputs. Applications include use as an HD-SDI fiber transmitter with additional monitoring and reclocked coax feeds. Or the board can have a dual receiver (two fiber inputs) or a transceiver (one fiber input and one fiber output).

All parameters can be adjusted directly from the board itself or via standard HTML web browsers or via the Newton Control Panel (when installed in network-equipped chassis). In addition NetConfig and CommandCenter can be used for remote configuration and signal health monitoring.

This is a monitoring device so, in order to provide the fastest possible conversion, the board does not perform de-interlacing and consequently it has an extremely short processing delay of 0.95 ms.

  • Reclocked distribution of HD-SDI signals for reconstructed input fan-out
  • SD-SDI monitoring
  • Can distribute both HD-SDI and SD-SDI with automatic format detection for flexible future-proof system architectures
  • Provides SD monitoring output whether input is SD or HD
  • Very high-density solution
  • Accepts optional fiber transmitter to provide optical, HD-SDI, and SD-SDI monitoring outputs for combined local/remote systems
  • Configurable as fiber receiver with four HD-SDI outputs and SD-SDI monitoring
  • High-quality downscaled signals (embedded audio and HANC data will be passed on all SDI outputs except for downscaled HD monitoring outputs)
  • Where an SD-SDI monitoring feed is required
  • HD-SDI distribution alongside SD-SDI monitoring
  • Rate-agile systems requiring consistent SD feed monitoring
  • A fiber receiver with SD monitoring
  • A fiber transmitter with local HD and SD monitoring feeds

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.
