HCO-1822 HD/SD/ASI Changeover with Embedded Audio & Metadata

The HCO-1822 is a 2x1 HD/SD/ASI change-over which supports 16 channels of embedded audio and metadata. Change-overs are performed electronically by the HCO-1822's internal router. The module can perform a video and audio "Clean & Silent Switch" between sources using the CS option. In the event of a power failure, the signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output. Relays are fully controllable via GPI. Input selection can be performed automatically or manually.

FEATURES

  • Two source inputs and two outputs: program and preview
  • Supports HD (1080i50/59.94, 720p50/59.94) and SD (525, 625)
  • Electronic switching with relay backup (on rear module) maintains selected input with power loss
  • Automatic mode using internal signal analysis with alarm parameters
  • Manual change-over by local frame controller, iControl, iControl Solo or GPI
  • Alarm reporting to iControl facility monitoring and control system
  • Preview output selectable to follow PGM OUT or any of video inputs
  • Compatible with iControl end-to-end A/V fingerprint analyzer for lip sync error detection and measurement
  • GPI I/O (IN 1, IN 2, AUTO, BYPASS)
  • Optional clean switch function (video and 16 channels of audio)
  • GPI outputs give status of selected source for tallies
  • Reference input with passive loop through
  • Two line timing window with CS option
  • Thumbnail and audio level meter streaming
