Crystal Vision Introduction

1 Introduction

The ShARC102-XP is a single channel, broadcast quality, 10 bit serial digital video aspect

ratio converter. The ShARC204-XP is a dual 10 bit serial digital video aspect ratio

converter permitting 24 independent channels in a 2U frame. The module can be controlled

locally from the card edge or by frame active front panel. Remote control is possible using

Crystal Vision’s active control panel REMIND, or Statesman PC Control Software. The

GPI port can also be used for 442 control or simple switching, providing a final method of

remote use.

Dedicating the image processing to these conversions allows a higher quality output

compared with multi-purpose ARCs. The result is low levels of aliasing and banding

coupled with a wide frequency response. No vertical processing is employed so the

propagation delay is minimised.

Two main operational modes are available for each channel: convert mode and bypass

mode. In each convert mode, two conversion types are available.

One stretches horizontally the central 75% of the input image to the full width of the output

picture monitor. This permits a 16:9 input to be displayed correctly on a 4:3 picture

monitor. The second conversion squashes horizontally the entire input image to 75% of its

size and puts this in the centre of the output image with black bands down the sides. This

permits a 4:3 input to be displayed correctly on a 16:9 picture monitor.

ShARC-XP conversions

Crystal Vision Introduction

ShARC-XPUserManualR2.11 421/09/05

625 or 525 line standard outputs are produced with automatic standard detection. EDH

transmission is added to the output. Digital audio and 10 bit ancillary data is passed

through unprocessed. There is a fixed propagation delay of 10s between input data and

output data even when bypass mode is selected.

The unit will plug into the front of the rack frame and the universal connection system will

allow a mixture of Crystal Vision modules, without the use of extra rear panels, in 4U, 2U,

1U frames and desk top boxes.

The hinged front panel of the case reveals user control of the card and also LED indication

of status. There is a four way piano switch to select modes of operation. Further

configuration is possible using movable links.

ShARC102-XP

Crystal Vision Introduction

ShARC-XPUserManualR2.11 521/09/05

The ShARC204-XP has 2 channels with independent control of their respective conversion

settings.

ShARC204-XP

Both the ShARC102-XP and ShARC204-XP have up to five methods of control.

•Board edge switches allow control and monitoring of conversion status

•Active control panel, either frame front or remote panel (REMIND)

•Statesman PC Control

•General Purpose Interface (GPI) with status ‘tally’

•Third party 422 control via GPI port

2 Hardware installation

2.1 Module configuration

The ShARC-XP has a large number of jumper links of which two sets are user adjustable.

The remainder jumper links are factory set and should not be reconfigured by the user, as

it is likely to result in the board malfunctioning. Where there is an NTSC requirement to

place closed caption data on lines 20/21 the ShARC-XP can leave these lines

unprocessed.

Hand shaking None

Please contact factory for remote protocol.

The NODE rotary switch SW2 selects one of 16 different remote protocol addresses for

the board when used in Crystal Vision frames FR1-6 and FR2-12. The NODE rotary

switch SW2 should be left in the ‘0’ position when used in an FR2-12AV or frame from

the Indigo range. The remote protocol address can be read from the slot position the board

is plugged into.

2.4 Rear modules and signal I/O

The Indigo 4 4U frames will house up to 24 single height modules with up to three power

supplies. The FR2AV and Indigo 2U frames will house up to 12 single height modules

and have dual power supplies. The FR1AV and Indigo 1U frames will house six single

height modules and a single power supply. The DTBAV and Indigo desk top boxes have a

built-in power supply and will house up to two single height modules.

2.5 General Purpose Interface (GPI)

ShARC-XP, as with most Crystal Vision modules, is equipped with GPI control I/O.

Remote control of the aspect ratio conversion mode on each channel other than via the

serial remote protocols is possible.

Remote connections

For Channel 1, DIL 1 and DIL 2 need to be in the ‘UP’ position. Jumpers on J1, J4, J16

and J17 need to be moved on to their GPI position. Remote control via auxiliary RS422

will no longer be possible. In this configuration a remote switch shorting to ground can be

as defined below. Pull-up resistors are already present.

Crystal Vision Hardware Installation

ShARC-XPUserManualR2.11 921/09/05

For Channel 2, DIL 3 and DIL 4 need to be in the ‘UP’ position. Likewise jumpers on J1,

J4, J16 and J17 need to be moved on to their GPI position. Again remote control via

auxiliary RS422 will no longer be possible. In this configuration a remote switch shorting

to ground can be as defined below. Pull-up resistors are already present.

Each slot has an associated set of connections on a socket and on a plug. The letters in the

table below refer to the connections described elsewhere in the manual.

Each slot has an associated set of connections on the frame rear-panel remote connectors.

The tables below show the GPI connections and describe their action.

Table showing GPI (General PurposeInterface) control

As supplied, each GPI output has a 330Ohm resistor in series with its output. This allows

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

Note: Latching switches are required

If DIP switches are used and then GPI is used, the last GPI command becomes the control

method. This may lead to the DIP switch settings not corresponding to the output. To

resume DIP control again, toggle the required DIP switch.
