1 Introduction
The ENC116 is a 10-bit broadcast quality Serial Digital to Analogue Composite
converter. It accepts either 625 or 525 line input, with automatic detection.
There is one reclocked serial digital output and six analogue PAL/NTSC outputs. The
available outputs depend on the rear module used. Normal single height rear modules
allow access to three of the analogue outputs, whilst an extra three analogue outputs and
one analogue reference loop-through are available in certain frames with alternative rear
modules. On-board links allow the selection of all composite outputs, or a mixture of
composite and Y/C outputs.
Remote control is possible from a front panel control and a remote panel using RS-422 or
RS-232.
The main features are as follows:
•compact single height module
•converts SDI signals to composite and Y/C
•genlock and free-run modes
•4.9 line time-base corrector
•automatic or manual PAL/NTSC standard selection
•adjustable timing, gains and levels
•card edge, Statesman and active panel control

Crystal Vision Introduction
29/09/06ENC116V4 Operational Manual V4_2 4ENC116 User Manual V4.2
A 4.9 line time-base corrector is included on both reference & video paths, which allows
serial digital video which has been delayed through prior processing to be re-timed
without the use of external delays or a multi-output SPG.
Two main operational modes are available: genlock mode and free-run mode. In genlock
mode, the composite output is time-base corrected & phase-locked to reference. In free-
run mode, the composite output is locked to the syncs embedded in the serial digital data
stream with phase reset every 8 fields.
If the reference is removed, the encoder switches to freerun mode and output timing
continues as if the reference were still present. If the reference returns, the encoder
genlocks after 1.5 seconds.
If the serial input is removed, the encoder outputs black & burst or one of 3 test patterns
selectable from the local/remote menu. PAL/NTSC standard selected by DIL switch 3.
Note: There may be some picture disturbance as the encoder switches modes or after a change of
standard as the encoder re-acquires genlock.
Output timing can be set to be the same as the analogue reference, or it can be offset to be
between 4µs earlier than the reference and 4.9 lines later. The SDI video input must be
earlier than the required output by a minimum of 4.3µs and a maximum of 4.9 lines. If the
input is outside this window, a valid composite output will still be created, but the picture
content will be vertically offset.
Frame packing density
The ENC116 is a 100mm x 266mm module, which fits in the three standard frames and
can be integrated with any boards from the company’s full product range. It may be used
with the single slot RM01 and RM23 rear connectors, the double slot RM18 rear
connector and the quadruple slot RM02 rear connector.
The RM01 and RM23 single slot rear connectors allows up to 12 modules in a 2U frame,
6 modules in a 1U frame and 2 modules in a desktop box. The RM18 double slot rear
connector accommodates one module but provides access to all ENC116 I/O connections.
The quadruple slot RM02 rear connector accommodates three modules and provides a
mix between packing density and I/O access. It can only be used in 2U frames.

2 Statesman PC control
The Crystal Vision Statesman PC control software is designed to control a range of
Crystal Vision modules via serial control from a PC. Statesman provides a user friendly
means of configuring and operating Crystal Vision modules with the benefit of see-at-a-
glance status monitoring. Most functions can be accessed from Statesman menus.
The main Statesman application communicates with each module in a frame through an
active or Statesman enabled control panel. Statesman control is not possible with only a
passive panel.
Minimum pre-requisites:
•A PC running either Windows 2000 or Windows XP is recommended
•A parallel port dongle for Statesman PCs with attached Crystal Vision frames
•An RS422 serial connection from the host PC to the Control/422 RJ45 or
Remote/RMT 2 connector on Crystal Vision frames
•An active or Statesman enabled 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
2.1 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.
Warning: Always ensure that the active front panel (if fitted) is in STATESMAN mode. If the front
panel is active, control via Statesman will be subject to high latency and the response to
changes will be slow.

Timing and status
The timing tab provides access to the following
•Vertical delay in lines
•Horizontal delay in pixels
•Fine horizontal delay in 1/32 pixel steps
•Genlock enable
•Status
Timing tab
Vertical delay
Slider adjusts delay from 0 to 5 lines in one-line steps. CAL button zeros the current
setting.
Horizontal delay
Slider adjusts delay from –4µs to 1 line in 7 pixel (approx. 0.5 µsec) steps. CAL button
minimises the current setting.
Sub-pixel delay
Slider adjusts delay from 0 to 1 pixels in 1/32 pixel (2ns) steps. CAL button zeros the
current setting.
Genlock enable
Place a tick by Genlock Enable to ensure that the output is sync and burst locked to the
supplied reference. Remove the tick and the output will be sync-locked to the serial
digital input.
If Genlock is ticked but the reference input is absent, the output will be sync-locked to
serial digital input. If there are no SDI or reference inputs the output will be black & burst
(or test patterns if selected).
Status
Input, reference presence and standard are shown along with FIFO and Genlock status.
