1Introduction

ViPA102 is a 10 bit video proc-amp allowing flexible independent adjustments of a

digital signal image in the YUV colour space, essential for correcting transmission errors

and colour space or A to D conversion errors.

ViPA102 passes all ancillary data, including embedded audio, transparently. Sixteen

memories are provided to store user-defined adjustments and there is GPI output

indication of YUV clipping. Control options include active frame front panel, remote

panel and the Statesman PC Control System.

ViPA102 10-bit processing amplifier

The main features are as follows:

•Digital processing amplifier

•12 ViPA modules fit in 2U (24 in 4U, 6 in 1U, 2 in desk top box)

•Allows independent digital image adjustments in YUV domain

•Tools to adjust level, gain, soft clipping and timing

•All limiting has adjustable softness

•Enforces CCIR601 dynamic range specification

•Bypass control

•Passes ancillary information

•Sixteen user memories

•EDH generation

•Flexible control

Crystal Vision Introduction

ViPA102 User Manual R1.2 404/07/2007

The ViPA102 has one input and two outputs and is based on a 100mm x 266mm module,

which fits in all Crystal Vision frames and can be integrated with any boards from the

company’s full product range. It uses the RM01 rear connector.

Processing modes

Processing modes are as follows:

•Advance/retard Y/C offset delay in 148ns steps

•Advance/retard overall horizontal delay (74ns increments)

•Correct for NTSC colour shift (Hue) errors on the U and V channels

•Increase/decrease Y, U and V channel lift and gain independently

•Set and soft limit Y, U, and V channel positive (Hi) and negative (Lo)

excursions independently

•Set horizontal and vertical active picture area cropping region on final output

Independent YUV adjustable soft clipping ensures colours do not overrun the CCIR601

specification by forcing the picture to remain within the valid dynamic signal range whilst

avoiding picture artefacts caused by hard clipping.

The adjustable horizontal and vertical cropping may be used to clean up picture edges.

For example, the vertical crop can be used to remove widescreen-signalling information

now part of the active picture following aspect ratio conversion.

If no correction is required processing is completely transparent, preserving signal

integrity.

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 UV channels have

one clipping control for each colour component.

2Hardware installation

The ViPA102 video proc-amp is a single height module that 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 Indigo 4 4U frame will house up to 24 single height modules with up to three power

supplies. The Indigo 2 2U frame will house up to 12 single height modules and dual

power supplies. The Indigo 1 1U frame will house six single height modules and a

single/dual power supply. The Indigo desk top box has a built-in power supply and will

house up to two single height modules.

Note: For details of fitting rear connectors please refer to the appropriate frame manual.

2.2 ViPA102 configuration

The jumper links on the board are set correctly when ViPA102 is tested before despatch

and should be left as set at the factory. The following information is for jumper position

confirmation only.

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 in GP 0 – 3 positions

PL7 Selects GPI 4 (IN/FADER/OUT) and GPI 5 (IN/POWER/OUT) function – default is OUT

PA43/PA65 Not used

2.3 General Purpose Interface (GPI)

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.

As supplied, each GPI output has a 270Ωresistor in series with its output. This allows for

an external LED to be driven, connected to a DC voltage of +5V.

Each General Purpose Input (GPI) is fitted with a 6800Ωresistor connected to the internal

+5V.

The 16 user preset configurations can be recalled using binary notation.
