Crystal Vision Introduction Block diagram ViViD 3GT-20 Functional Block Diagram Input video from either the BNC input or the (optional) optical input is equalised and then re-clocked. The video signal is passed to a delay line whose length is adjustable in seconds, frames, line and pixel increments under control of the CPU.
Crystal Vision Introduction Timecode delay The timecode delay through a ViVid 3GT-20 is set by the ‘Timecode Delay Mode’ control (see Timecode Delay in section Control Descriptions) to be either the same as the video signal or to a minimum value.

Crystal Vision General Purpose Interface 4 General Purpose Interface Introduction Each frame slot has up to six connections ‘a-f’ for GPI control and monitoring. These connections are available at the rear of the frame on the 26-way D-Type remote connectors.
Crystal Vision General Purpose Interface Alarms GPI outputs 5 and 6 (e, f) can be configured to be asserted (logic ‘L’) for a selection of error conditions. For each GPO there are four separate alarm conditions and all of the alarm conditions can be assigned to both.
Crystal Vision Control and Status Monitoring 5 Control and Status Monitoring ViViD 3GT-20 controls and status can be accessed most easily by Crystal Vision’s ‘VisionWeb’ PC software but also by card edge control and the rack front panel. Board edge control was removed from ViViD 3GT-20 in 2019. Therefore the card edge control information detailed here is only relevant for older versions of the product.
Crystal Vision Control and Status Monitoring Reading card edge LEDs Card edge LEDs may be used in conjunction with status information from any connected remote status panel display or from VisionWeb or Statesman if available. Refer also to the troubleshooting chapter for more help with solving problems and monitoring status information.
Crystal Vision Control and Status Monitoring Using the front control panel At power up, the LEDs of all eight control panel keys will illuminate briefly. Once the panel has completed its power up and configuration sequence, the panel will enter its status mode and display the current software version and frame IP address.

Control Descriptions. Controlling cards via VisionWeb Crystal Vision cards use an XML file to create a control database that is used by the card’s front-edge controller, the Indigo frame front panel controller and VisionWeb software. VisionWeb software offers a full range of controls with slider controls etc.

The controls of ViViD 3GT-20 are accessible from the front panel, the board edge or from Crystal Vision’s VisionWeb software. The description of controls used in this manual is based on VisionWeb GUI screen grabs but the path to locate controls via the front panel or board edge follows the same logic.
Crystal Vision Control Descriptions Status Menu Video Status Display presence, standard and status of incoming video signal. Input Present On when input video is present. Displays video standard of incoming video. i.e. 1080i 50, Input Standard 1080p 50, 720p 50, 625, 525 etc.
Crystal Vision Control Descriptions Group 1 – 4 Present On when embedded audio group is present in video. Timecode Status Displays presence of timecode Present On when ATC or VITC timecode is present in video. Video Settings Menu Video Delay These controls set the length of the delay period in seconds, frames, lines and pixels.
Crystal Vision Control Descriptions Timecode Delay These controls set the timecode by-pass delay to be the same as the video or to the minimum value necessary to reinsert timecode into the same video line. Select which SD line number to extract VITC and reinsert into the delayed video.
Crystal Vision Control Descriptions Output Configure These controls force the output video to a manually selected state or automatically if the input fails. Force output to the selected state Force Output regardless of input condition. Select to enable a three second freeze of last received input frame...

Crystal Vision Control Descriptions YUV Proc Amp Alter the lift and gain of the Y, U and V components of the video path. YUV Lift Alter the DC offset of the YUV components by +/- 10%. YUV Gain Alter the gain of the YUV components between 80% to 120%.
Crystal Vision Control Descriptions Fibre Input Enable Select fibre optic for video input. Select to enable optical as the input video source instead of Fibre Input Enable BNC. N.B. The optional SPF module and RM57 rear module must be fitted.
Crystal Vision Control Descriptions Presets, Resets And GPOs Presets Up to 16 user-defined configurations may be stored and recalled either from VisionWeb or through the use of external GPIs. Presets store the board setup data including operating mode card status.
Crystal Vision Control Descriptions Resets Reset ViViD 3GT-20 settings to default values. Fact Res Exc Reset the board to default settings but leave preset memories Presets unaffected. Fact Res Inc Reset the board to default settings and erase preset memories.
Crystal Vision Control Descriptions Alarm Delay Time Set the time that the ‘Input Video Black’ and ‘Input Video Frozen’ conditions must be active before the alarms are asserted. Set the time period that the video input must remain black Black before asserting the GPO.
