1 Introduction

The DEC101S is an analogue composite or Y/C to serial digital video decoder. It contains

an 8-bit synchroniser allowing the serial digital output to be timed to an analogue

reference.

The decoder provides 8-bit conversion for less stable PAL or NTSC video, as is often the

case with VHS or satellite feeds.

The main features are as follows:

•compact single height module

•converts any composite or Y/C signal to SDI

•8-bit frame synchroniser

•automatic or manual PAL/NTSC standard selection

•adjustable timing, gain and black level

•loop or terminate external analogue video reference input

•card edge, Statesman and remote control facilities

The DEC101S analogue composite or Y/C to serial digital video decoder

The DEC101S is a 100mm x 266mm module, which fits in the all standard frames and

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

single height RM01, double height RM18 and triple height RM02 rear connectors in

Indigo and other Crystal Vision frames.

Operating modes

The DEC101S can operate in the following modes.

Input modes Description

8-bit composite

8-bit Y/C (S-video)

The highly tolerant robust inputs are particularly suitable for use with

poorly timed sources such as VHS recorders or satellite feeds.

Each operating mode has its own luminance/chrominance gain and black level 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.

Output timing

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

analogue timing references. These are an external reference 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 75 Ohm as per EBU N14-1988 is preferred.

When no external analogue timing reference present the serial output is timed to the free

running clock.

Manual scope

This manual refers to module firmware version 2.87 or later.

Crystal Vision Statesman

2 Statesman

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 through an

active control panel with or without an LCD display. Statesman will not be able to detect

modules used in a frame with only a passive front panel.

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 Remote 2 connector on an

FR1AV or FR2AV Crystal Vision frame with at least one DEC101S 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.

2.2 Statesman operation

Once Statesman is configured it should automatically detect any statesman compatible

modules in the connected frame or frames and display them in the main application left

hand explorer-style window.

Open any frame by clicking on the ‘+’ sign or by double clicking on a frame. Installed

modules should be shown with module icons. Frame and module icons can be named as

desired by right-clicking or using the edit menu and choosing rename.

To aid user recognition of module and frame status quickly, the following colour and size

coding is used:

•A module is shown present by full colour and absent by greyed colour

•A module is shown open by large icon size and closed by small icon

•A module is the source of an active alarm if red and not alarmed if green

Double-clicking on a module will enable the display of the main application menus.

Statesman main application window

The two large control panes shown in the upper and lower halves of the window may

display different menus for the same card, or controls for different cards. Click on the

horizontal button-bar between the two panes to close the lower plane or drag the button to

vary the size of the panes.

Note: For further details of Statesman configuration and operation please refer to the Statesman

manual.

Output settings

Output settings are as follows:

Output setting Description

VBI Blanked

/Unblanked

VBI data blocked or passed unprocessed (unblanked) on luminance channel

Pedestal (NTSC

only)

ON: 7.5 IRE subtracted from black level, gain increased

OFF: Black level and gain settings assume no 7.5 IRE offset

Note: Vertical Blanking Interval data is normally present in PAL on lines 7-22 and 319-335 and in

NTSC on lines 10-20 and 273-282.

Status

Status indication is as follows:

Input setting Description

Input presence Green when input detected. Grey when no input detected.

Note: Refer to the installation section for details of the external analogue reference input loop or

terminate link on the module itself.

Gain and black level adjustment

The level adjustment pane of the Levels/Position tab provides access to the following:

•Luma gain

•Chroma gain

•Black level

Level adjustment controls (left hand pane)

Setting gain and black level

The luma/chroma gain and black level adjustments are independent for Composite and

Y/C modes. For example, if the unit is set up in composite mode and subsequently

adjusted in Y/C mode, the composite adjustments are maintained and will be restored

when composite operation is resumed.

Recalling defaults

To recall default settings press the 'Default' button.
