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 operation including DVB-ASI passthrough support
- Auto change-over from either input on pre-defined error conditions with user-definable change-over delay
- Input signal monitoring including SDI lock, ASI carrier detection, 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
