Miranda HCO-3901-OPT-CS Clean switch option - HCO-3901-OPT-CS
The HCO-3901 is a 3x1 3G*/HD/SD/ASI change-over which support 16 channels of embedded audio and metadata. The module can perform a video and audio "Clean and Silent Switch" between sources using the CS option. In the event of a power failure, the PGM 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.
Key Features
Two primary inputs: IN 1 and IN 2 plus one secondary: IN 3
Four outputs: main program and three previews
Supports 3G, HD (1080i50/59.94, 720p50/59.94) and SD (525, 625) or ASI input
Electronic switching with relay backup (on rear module) maintains selected input with power loss for Primary inputs IN 1 and IN 2
Automatic mode using internal signal analysis with alarm parameters for IN 1 and IN 2
Manual change-over by local frame controller, iControl, iControl Solo, RCP-200 or GPI (3DRP rear) for 3 inputs
Alarm reporting to iControl facility monitoring and control system
Compatible with iControl end-to-end A/V fingerprint analyzer for lip sync error detection and measurement
GPI in and out (IN 1, IN 2, IN 3, auto, bypass)
Optional clean switch function (video and 16 channels of audio) for IN 1 and IN 2
Optional on-board automatic loudness control by Grass Valley
Reference input with passive loop through (3DRP rear only)
Two line timing window with CS option
Thumbnail and audio level meter streaming for IN 1, IN 2 and PGM OUT
Loudness compliant to EBU R128-2014, ATSC A/85:2013 (FCC CALM compliant) and ARIB TR-B32 (ITU-R BS.1770-3)
