Crystal Vision Introduction

1Introduction

The DEC105S is an analogue composite or Y/C to serial digital video decoder. It contains

a 10 bit synchroniser allowing the serial digital output to be timed to an analogue

reference. The DEC105S also has a serial digital (SDI) input. This allows it to be used as

a synchroniser, with some additional control over gains and timing.

Two main operating modes are supported, 10 bit for professional quality PAL or NTSC

video and 8 bit for less stable PAL or NTSC video, as is often the case with VHS or

satellite feeds.

The decoder is fitted with a 3 line adaptive comb decoder and Crystal Vision’s own

bandsplit decoder which gives excellent decoding without the artefacts of a comb. This is

recommended when using broadcast PAL material. It is also designed to accommodate

jittery or damaged signals and will automatically switch to its tolerant 8 bit decoder mode

when a non-stable signal is received.

The main features are as follows:

•compact single height module

•converts composite or Y/C signals to SDI

•frame synchroniser with SDI input

•10 bit adaptive comb and PAL bandsplit filtering plus 8 bit input modes

•automatic or manual PAL/NTSC standard selection

•adjustable timing, gain and black level

•audio follow pulse for audio to video delay tracking

•GPI outputs for 8 bit lock, SDI present, ref present, std & audio follow pulse

•loop or terminate composite input and external analogue video reference input

•card edge, Statesman and remote control facilities

The DEC105S is a 100mm x 266mm module, which fits in all standard frames and can be

integrated with any boards from the company’s full product range. It uses the single

height RM01, RM23, and RM24, double height RM27 and quad height RM25 rear

connectors in the Indigo and FR-AV range of Crystal Vision frames. Note quad height

rear modules are limited to the 2U and 4U frames.

Operating modes

To provide optimum performance with a wide range of sources the DEC105S can operate

in a number of different modes.

Input modes Description

10 bit comb PAL/NTSC

composite Uses a line-based comb decoder, which mixes to simple decoder

when the comb would produce artefacts.

10 bit bandsplit PAL

composite High quality analogue bandsplit mode provides best results when

PAL material is unsuitable for line-based comb.

10 bit Y/C (S-video) Suitable for use with well-timed PAL sources.

8 bit composite

8 bit Y/C (S-video)

All 8 bit modes use a robust simple decoder. These highly tolerant

modes are particularly suitable for use with poorly timed sources

such as VHS recorders or satellite feeds.

Each operating mode has its own luminance and chrominance gain, offset and phase

settings and both 525 and 625 line standards have separate horizontal and vertical timing

settings. All these parameters are automatically maintained when power is cycled.

Crystal Vision Introduction

DEC105S User Manual R1.1 515/12/04

Output timing

Horizontal and vertical timing adjustments are provided which operate relative to one of

three analogue timing references. These are an external reference, the video input or an

internal free-running clock. The external reference can be video or composite syncs

although a composite black and burst plus 300mV syncs into 75Ohm as per EBU N14-

1988 is to be preferred.

If no analogue reference is provided the board will either time itself relative to the

composite or Y/C video input in 10 bit modes, or it will time its output to a free running

clock in 8 bit modes.

A horizontal offset delay adjustment varies the timing of the input video relative to input

syncs and blanking in 10 bit mode whichever source is the active reference.

Audio follow pulse

To allow an audio delay to track the video delay through the DEC105S, a TTL level pulse

is provided. This audio follow pulse is available from GPI5 and from a BNC socket on the

RM27 rear module. This pulse is output every frame. The length of the pulse (the time

between the rising and falling edge) is the same as the delay through the synchroniser.

General Purpose Interface (GPI)

The DEC105S, as with most Crystal Vision modules, is equipped with GPI control I/O.

GPI Low (<1V) High (+5V)

0‘a’ No connect

1‘b’ 8 bit lock Loss of 8 bit lock 8 bit locked

2‘c’ SDI present No SDI present SDI present

3‘d’ Reference present No reference present Reference present

4‘e’ Input standard 625 525

5‘f’ Audio follow pulse Pulse width equal to audio delay

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.

Crystal Vision Statesman

DEC105S User Manual R1.1 915/12/04

2Statesman

The Crystal Vision Statesman PC control software is designed to control a range of

Crystal Vision modules via serial control from a PC.

The main Statesman application communicates with each module in a frame that is fitted

with an active front panel. This panel can be with or without an LCD display. Statesman

will not normally be able to detect modules used in a frame with only a passive front

panel unless it is part of and active/passive combination.

2.1 Installing Statesman

Minimum pre-requisites:

•A PC running Windows 98, NT4 with SP 5 or higher Windows 2000 or

Windows XP

•A parallel port dongle supplied with the Statesman software package

•An RS422 serial connection from the host PC to the Indigo frame control input

or to Remote 2 connector on an FR1AV or FR2AV Crystal Vision frame with

at least one DEC105S module and/or other Statesman compatible module

•An active control panel MUST be fitted to the frame with version 1.63 or above

firmware – if it is an Indigo frame the firmware must be V1.04 or above

•An optional RS422 to RS232 converter if the PC has no RS422 ports

Installing Statesman

•Refer to the readme and/or help file on the CD before proceeding

•To view all application windows, set graphics resolution to at least 1024 x 768

•Remove any previous version of the Statesman software using the Add/Remove

Programs application in the Windows Control Panel

•Ensure that the Statesman dongle is fitted to the parallel port of the host PC

•Insert the Statesman CD and the installation should start immediately – if it

does not, run the setup.exe file on the CD

•Obey any installation program prompts and restart the PC when prompted

Running Statesman for the first time

The Statesman PC Control System may be run from the Crystal Vision programs folder

via the Start menu or by double-clicking on the Crystal Vision.exe file in the installed

program directory.

When the program runs it will require licence information and an administrator name and

password. It will also need to know which computer port is being used to connect to a

Crystal Vision frame(s).

Note: For further details of Statesman configuration please refer to the Statesman manual.
