1 Introduction
ViViD 3G is a range of four 3Gb/s-compatible variable video delays. The maximum delays
available are ten seconds for 3Gb/s, 20 seconds for HD and 110 seconds for SD. Delays are
adjustable in seconds,frames, lines and pixels for precise matching of system delays. ViViD
versions 3GS and 3GS-20 include – in addition to the delay line – a frame synchroniser to
lock the output video to station reference.
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, 720p59.94, 1080i50,
1080i59.94, 1080p50, 1080p59.94, 1080psf23.98, 1080psf24.
•
Optimise the video:
video proc-amp allows adjustment of video gain, black level
and independent YUV gains. ViViD 3GS and 3GS-20 also feature a full-frame
synchroniser that re-times the video to match an external reference.
•
Multiple video outputs
– Four delayed outputs save the need for an additional DA.
•
Control
of ViViD 3G 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.
•
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,
or (ViViD 3GS/3GS-20 only) reference is missing.
