IQHCO51 3G/HD/SD Synchronized Changeover

The IQHCO51 provides backup protection for SDI signal paths with a clean and quiet switching feature. IQHCO51 uses video and audio input error monitoring to drive an 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, along with monitoring of the unselected inputs for video and audio signal confidence.

FEATURES

Key Features
  • 3 Gb/s SDI, HD-SDI and DVB-ASI operation with a synchronizer per input and RGB legalization
  • Auto change-over from either input on pre-
  • defined error conditions
  • User-definable change-over delay
  • Connectivity: 3 SDI inputs, analog reference input, up to 4 SDI outputs (2 main and 2 monitoring) and up to 8x GPI/O
  • Flexible routing with 4x1, 4x2, 3x1, 3x2, 2x1 and 2x2 configurations available
  • Input signal monitoring including SDI lock, EDH/CRC error, Freeze detection, Black detection, embedded audio loss and standard mismatch
  • Agile, router switching tolerant synchronizer operation with genlock adjustment allowing you to time any SDI signal to pixel accuracy with greater tolerance to mis-timed upstream SDI switching (up to ±10 lines), ensuring disturbance free picture output
  • Video controls including video gain, offset and hue, audio proc. amp features including channel level (sub-frame) routing, independent gain, invert and mute control with audio V-fade on input loss
  • Up to 32 channel embedded audio support and Dolby E compatibility
  • Input loss detection — default output of black/pattern and tone mute
  • Independent HANC and VANC blanking control per input
  • 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, and Media Biometrics Signature generation on program output provides full integration with Sigma media assurance systems
Options
  • Single mode fiber optic transmitter and receiver support — rear panel option
  • Advanced color corrector functionality that can be applied at each input — software license option
