IQHCO50 3G/HD/SD Changeover

The IQHCO50 provides backup protection for SDI signal paths using video and audio input error monitoring, resulting in automatic change-over to a backup feed on error state detection. A powerful rules engine is available to provide logical conditions for auto-switching, while GPI inputs and card edge control can force the unit to switch independent of signal state. Features include three selectable inputs and a dedicated TPG input, alongside monitoring of the unselected inputs for video and audio signal confidence.

FEATURES

  • 3 Gb/s SDI, HD-SDI, SD-SDI and DVB-ASI operation
  • Auto change-over from either input on pre-
  • defined error conditions with user-definable change-over delay
  • Input signal monitoring including SDI lock, EDH/CRC error, freeze detection, black detection, embedded audio loss and standard mismatch
  • Input loss detection — default output of black/pattern, tone/mute
  • Connectivity: 3 SDI inputs, up to 4 SDI outputs (2 main and 2 monitoring) and up to 8x GPI/O
  • Video controls including video gain, offset, hue and RGB legalization, with optional color correction
  • Up to 32-channel embedded audio support and Dolby E compatibility
  • Independent HANC and VANC blanking control per output
  • Card edge control for input switch and LED status indicators
  • Selectable SDI monitoring outputs enable either input to be monitored independent of the main signal selection
  • Built-in test pattern generator and audio tone generator assignable per input for testing purposes and provision for a dedicated routable TPG fourth input
  • 16x user memories, save/recall/rename
  • Input signal relay bypass versions available (options for either basic input 1 to output 1, or follow input select bypass)
  • RollCall monitoring allows all signal paths to be managed
