MECHANICAL
'Double decker' Crystal Vision module 266mm x 100mm (uses two frame slots)
Weight: 300g
Power consumption: 14 Watts

VIDEO INPUTS
Three HD or SD inputs (Foreground, Background and Key)
270Mbit to 1.485Gbit compliant to SMPTE 259M and SMPTE 292M
All common SD and HD formats supported: 576i50, 486i59.94, 720p50, 720p59.94, 720p60, 1035i59.94, 1035i60, 1080PsF23.98, 1080PsF24, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97 and 1080p30. All inputs must be same format
Reference timing can be selected to come from Foreground, Background or Key input
Delay through board: 8us min to 64us max
Max input buffer length one line (selectable)

VIDEO OUTPUTS
Two main outputs and two auxiliary outputs accessed by using RM32 and RM40 rear modules. Relay bypass protection of Background with RM40
HD or SD outputs - outputs follow inputs format
270Mbit to 1.485Gbit compliant to SMPTE 259M and SMPTE 292M
Both main and auxiliary outputs can be used to show Main Output, Suppressed Foreground, Foreground Input, Background Input, Chroma Key, Processed Key, Self-Key or Matte Generator

CHROMA KEY
Cursor-based auto setup will set all variables and be suitable for most applications. Fine improvements can be made by adjusting the following:
Hue (Colour for chroma key)
Acceptance Angle (Range of hue to generate key)
Max Clip and Min Clip (Set chroma level for full chroma key and zero chroma key)
Y Correction (Luminance alteration of keying to remove key spill)
Suppression Angle (Range of hue to completely suppress in Foreground)
Y Suppression (Amount of luminance to be suppressed in coloured keying area of Foreground)
Shadow Enhance (Fine adjustment of shadow effect)
Key Shrink (On/Off. Key shrink reduces the size of the chroma key by a fraction of a clock. Reduces the possibility of a black line round the presenter in some lighting conditions)
Use additive keying to get best results for shadows and transparent objects. (Relies on a good, well-lit backdrop.)
Chroma key can be inverted or turned off leaving the External Key and Background/Foreground masks. When chroma keying is switched off keying can be from Foreground luminance level (see Luminance Key)

Downstream processing:
Keyed Background is combined with Foreground or Suppressed Foreground
Fade to Foreground or Background, followed by a fade to black (fade to black on main outputs only)

EXTERNAL KEY
External Key and two internal masks (Background and Foreground) can be combined with the chroma key for additional effects. Controls here include:
External Key (On/Off, Invert, Max Clip and Min Clip)
Background and Foreground masks (On/Off, Invert, Window Adjust [horizontal and vertical position, horizontal and vertical size])
Key Fade function (to fade Foreground or Background in and out)

LUMINANCE KEY (SELF-KEY)
Self-key is available from Foreground input
Adjustable Key Max, Key Min and Inversion or grey level and range
Internal colour matte generator can be used as a fill for keying (also available with chroma key)

MIX AND WIPE
Foreground and Background can be mixed or wiped
Wipes include: horizontal, vertical, horizontal blind, vertical blind, left corner, right corner, box and cross

ANCILLARY DATA / EMBEDDED AUDIO
Ancillary data and embedded audio is taken from the selected timing reference

GPI INPUT LEVELS
Active: pull to ground, pulled up to +5V through 1 kohm

GPI OUTPUT LEVELS
Electrically: Open drain transistors 48V, 270 ohm current limit resistors. Pulled up to +5V through 6800 ohm

GPI INPUTS
Four GPI inputs can be used to fade to black, fade external key up and down, fade chroma key up and down, and mix between Foreground and Background inputs
Two GPI inputs can be used to recall one of four presets

GPI OUTPUTS
One GPI output shows state of External Key
