1 Introduction
CoCo104 is a 10 bit digital colour corrector and legaliser, which allows independent
digital image adjustments in YUV and RGB domains, essential for maintaining colour
fidelity. CoCo104 passes all ancillary data, including embedded audio, transparently. 16
memories are provided to store user-defined adjustments and there is GPI output
indication of YUV and RGB clip status.
CoCo104 colour corrector and legaliser
The main features are as follows:
Digital colour corrector and legaliser
Independent digital image adjustments in YUV and RGB domains
Tools to adjust level, gain, soft clipping and timing
All limiting has adjustable softness
Performs true colour correction using RGB lift and gain
Changes YUV colours illegal in RGB to be valid in RGB
Overall gamma and independent adjustment of red, green and blue gamma
Split-screen output to preview adjustments – AUX out only
Bypass control
Passes ancillary information
16 user memories
EDH generation
Control from dedicated 1U CoCo Controller, Statesman or active panel
CoCo104 is a 100mm x 266mm module, which fits in all of the standard frames and can
be integrated with any boards from the company’s full product range. It uses the RM01
rear connector.
The 4U Indigo 4 frame will house up to 24 modules and triple power supplies.
The 2U Indigo 2 or FR2AV frame will house up to 12 modules and dual power supplies.
Crystal Vision Introduction
CoCo104 User Manual R2.0 526/09/05
The 1U Indigo 1 or FR1AV frame will house six modules and a single power supply.
The 1U Indigo DT desk top box has a built-in power supply and will house up to two
modules.
On the 1U, 2U and 4U frames a hinged front panel gives access to the PSU and all
modules. The desk top box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.
Applications include correcting computer-generated or post-production output and
ensuring broadcast colour gamut is always legal.
Processing modes
Advance/retard Y/C offset delay
Advance/retard overall horizontal delay (74ns increments)
Hue shift UV channels
Increase/decrease Y, U and V channel lift and gain independently
Set and soft limit Y channel positive (Hi) and negative (Lo) excursions
Set and soft limit U, and V channel positive/negative excursions symmetrically
Increase/decrease RGB channel lift and gain independently
Increase/decrease RGB gamma independently and together
Set and soft limit RGB channel positive excursions independently
Set horizontal and vertical active picture area cropping region on final output
Soft limiting
Soft limiting or clipping is provided by a combination of adjustable threshold and slope
controls. The luminance channel has both high and low limiting, whilst the UV and RGB
channels have one clipping control for each colour component. UV clipping operates
symmetrically about black level and RGB clipping is adjustable at the high level only.

CoCo104 soft limiting
Note: Although there is no provision for an RGB lower clip adjustment, when RGB clipping is
enabled, excessive negative RGB excursions are automatically prevented.

2 Hardware installation
The CoCo104 colour corrector and legaliser is a single height module which fits into all
Crystal Vision rack frames. All modules can be plugged in and removed while the frame
is powered without damage.
2.1 Rear modules and signal I/O
The CoCo104 module fits into all Crystal Vision rack frames. All modules can be
plugged in and removed while the frame is powered without damage.
CoCo104 is used with the RM01 single slot rear connector in all Crystal Vision frames.
The 4U Indigo 4 frame will house up to 24 modules and triple power supplies.
The 2U Indigo 2 or FR2AV frame will house up to 12 modules and dual power supplies.
The 1U Indigo 1 or FR1AV frame will house 6 modules and a single power supply.
The 1U Indigo DT desk top box has a built-in power supply and will house up to 2
modules.
On the 1U, 2U and 4U frames a hinged front panel gives access to the PSU and all
modules. The desk top box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.

2.2 CoCo104 configuration
The jumper links on the board are set correctly when CoCo104 is tested before despatch and should be
left as set at the factory. The following information is for jumper position confirmation only.
J5
CoCo104 showing default factory jumpers
Link positions - board viewed as above
Link Required position
J8 & J9 Must be in the ON position
J2, J3, J5, J7 Must be in the SLOW position
J6 Leave jumper in place
J14 Leave in WDOG position
J1, J4, J16, J17 Leave all four jumpers in the right hand position to enable the CoCo Controller panel. Leave
in the left-hand position for GPI outputs
PL7 Selects GPI ‘e’ (IN/FADER/OUT) and GPI ‘f’ (IN/POWER/OUT) function – default is OUT
PA43/PA65 Not used

2.3 Using module GPIs
Each slot has an associated set of GPI connections for remote control and external status
outputs on the frame rear-panel remote connectors. For convenience, GPI lines are
associated with reference codes ‘a’ to ‘f’ in the connector pin-out tables for each frame.
GPI lines can be used for either remote preset control or a second serial port for the CoCo
Controller panel. GPI lines ‘e’ and ‘f’ are reserved for an optional remote fader.
To enable GPI preset selection, ensure that the four jumpers J1, J4, J16 and J17 are all
positioned away from the edge connector.
The following table shows the binary weighted code required to recall presets 1 to 16
according to the state of GPI ‘e’. A ‘0’ is an open GPI input and a ‘1’ is a grounded GPI
input.
Recall Preset 12345678910 11 12 13 14 15 16
GPI ‘a’ 0101010101010101
GPI ‘b’ 0011001100110011
GPI ‘c’ 0000111100001111
GPI ‘d’ 0000000011111111
OPEN (+5V) GROUND
‘a’, ‘b’, ‘c’, ‘d’ See table above
‘e’ No action IN/FADER/OUT – depends on JP7
‘f’ No action IN/POWER/OUT – depends on JP7
GPI input assignment
GPI input connections have 10k Ωpull-up resistors to +5V. Closed-contact switches or
+5V to +24V logic levels can be used
GPI output connections (when provided) have 330Ωseries resistors fitted to drive LEDs
and 10k Ω pull-up to +5V (to drive a remote input).
Note: Jumpers PL 1, 4, 16 and 17 should be left in the left hand GPI position to enable normal
GPI operation and in the right hand position to enable RS485 comms for a CoCo
Controller.
