Crystal Vision Introduction
1 Introduction
ViViD 3GT-20 is a 3Gb/s-compatible variable video delay. The maximum delays
possible are ten seconds for 3Gb/s, 20 seconds for HD and 110 seconds for SD
signals. Delays are adjustable in seconds,frames, lines and pixels for precise
matching of system delays. The pass-through delay for ancillary timecode (ATC) or
VITC can be set to match the video signal or set to a minimum value to effectively
advance timecode with respect to the video.
The main features are as follows:
•Use with any source – works with 3Gb/s, HD and SD.
•Supports the following video standards: 625, 525, 720p50, 720p59, 1080i50,
1080i59.
•Optimise the video: video proc-amp allows adjustment of video gain, black level
and independent YUV gains.
•Multiple video outputs – Four delayed outputs save the need for an additional
DA.
•Control of ViViD 3GT-20 is most easily achieved with VisionWeb PC software
but also by an active front panel on the frame, a remote panel and SNMP. Board
edge control was also available prior to 2019.
•Optical connectivity – send signal beyond the local equipment bay with the
fibre input and output options.
•GPI control – 16 presets allow different delay values to be assigned then
recalled automatically by GPI.
•HANC and VANC blanking option.
•EDH insertion.
•Supports rear module connectors: RM41, RM57, RM67.
•Compatible with Crystal Vision standard frames available in 2U, 1U and desk
top box.
•Passes all timecode, AFD, subtitling information, Dolby E metadata and
embedded audio.
•Timecode pass-through delay can follow video or be set to minimum.
•Freeze output –Force output to freeze or produce black, blue or bars manually,
or automatically if input video lost.
•GPI Output Alarms – Two output alarms if input video is missing, black or
frozen.
ViViD 3GT-20 User Manual R1.1 320 January 2021

Crystal Vision Introduction
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. Following the delay
line is the timecode reinserter where previously extracted ATC packets or VITC data is
added to the video before the proc-amp where lift and gain can be applied to the video
components in the YUV or RGB domain. Finally, depending on the rear module fitted, the
video is output to the rear modules as either four BNC or three BNC and one optical
output.

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.
When set to ‘Follow Video Delay’ the timecode data remains encoded within the
video signal and passes through the video delay line to the video output with exactly
the same delay.
When set to ‘Minimum Delay’ timecode data is extracted from the incoming video
signal to bypass the video delay. A separate timecode delay is used to delay the
timecode by the minimum amount necessary for it to be reinserted into the delayed
video on the same line from where it was extracted.
The amount of timecode delay to achieve this depends on the amount of video delay
selected. The longer the video delay then the longer the timecode delay must be to
reinsert timecode into the original line. Timecode delay can be increased to a
maximum of one frame after which the delay reverts to zero and timecode is
reinserted into the original line but of the previous frame. At the video output the
reinserted timecode values will be effectively advanced by one frame for every frame
of video delay. In this way down-stream equipment will see the timecode value for a
event prior to the video image.
The precise amount of timecode delay depends on not only the video delay but also
the timing of the RP186 switch line to the start of active video.
For HD signals the original incoming ATC packets are marked for deletion prior to the
video delay and new packets are written on the same line when reinserted. For SD
signal the reinserted VITC overwrites the original data.
The diagram above shows two instances where the video is first delayed by 200
lines and then by 100 frames plus 200 lines. In the first instance a timecode delay
of 200 lines will align the input timecode for reinsertion into the the same line of
the same frame. The timecode values will remain unchanged as the timecode
delay is less than one frame. In the second instance the timecode delay will
remain at 200 lines but timecode reinsertion will be into a frame 100 frames later.
The timecode values will be 100 frames less than the delayed video.

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.
ViViD 3GT-20 has four GPI inputs and two GPI outputs.
Each General Purpose Interface (GPI) input is fitted with a 6800Ω resistor connected
to the internal +5V and in the following table, this equates to logic ‘H’, so with no
connections to the GPI lines, preset 1 (logic ‘HHHH’) will be selected. See the
‘Presets’ section on page 31 for details of inverting the GPI preset logic.
Each General Purpose Interface (GPI) output has a 270Ω resistor in series with its
output. This allows for an external LED to be driven, connected to a DC voltage of
+5V.
The GPI inputs can be programmed to automatically recall a previously saved preset
configuration. The 16 user preset configurations are selected using binary
notation.The two outputs can be programmed to assert themselves for a number of
different alarm conditions.

•Rotary control – shaft encoder used to select sub-menus or variable data.
Updating the display
The values displayed on an active front panel are only updated when an adjustment
is made and when changing menu level. If changes occur through the use of card
edge controls or other remote control, the text displayed on the active front panel will
not be updated immediately. If necessary, use the upward arrow to leave and then re-
enter a menu to update the display.

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. similar to that available with the older Statesman PC software.
Accessing the Indigo Home page with a PC browser via the Ethernet connector of
an Ethernet-enabled frame will display a list of the cards fitted. (See appropriate
