1. General Information
1.1 Introduction
Thank you for purchasing the DV2000—a versatile digital video platform for closed caption,
text, and graphics generation. DV2000 is the industry’s first closed caption encoder and
subtitle generator combined in a single unit. With it you can generate slates, bugs, TV rating
icons and subtitles while encoding closed caption and XDS data. Post production and tape
duplication facilities can perform these jobs in a single pass. Broadcasters can comply to
FCC rules with a single unit by encoding closed captions and “V-chip” data while simulta-
neously displaying on-screen TV rating icons.
DV2000 is constructed in a modular fashion. All of the major components plug into industry
standard slots. The modular architecture allows for easy repairs and upgrades in the field.
There are slots available for options or for other functions that our industry may require in
the future.
Easy Operation
A common complaint in the caption industry is that post houses and tape duplicators must
deal with caption files with different formats and encoding requirements. DV2000 addresses
this by reading all of the popular caption file formats. The encoder automatically determines
the proper settings by looking at the data contained in the file—the operator doesn’t even
have to specify the format.
DV2000 can read individual caption files, or it can read script files. A script file may contain
instructions to display slates, logos, icons, etc. and it may also start a caption encoding
session. Caption agencies may prepare script files that perform special tasks. Script files can
automatically set DV2000 to the proper configuration to perform an encoding or subtitling
job. ULTECH provides script templates which make it easy for caption agencies or supervi-
sors to create custom scripts.
In a broadcast environment, DV2000 can act as a caption server. Caption data does not have
to reside in the VBI of programs on videotape; it can be encoded “on-the-fly” as the program
airs. Captions may be downloaded to DV2000’s hard disk via network or modem interface.
A play list may be generated that instructs DV2000 to encode a sequence of shows based on
time code. This technique saves a tape generation, plus it allows easier reformatting of
captions if a show is edited.
1. General Information

6 ULTECH DV2000 User’s Manual
1.2 Closed Caption Encoder
Caption encoding is where DV2000 truly excels. The heart of the encoder is the CCX
caption encoding software module. CCX is ULTECH’s PC-based closed caption encoding
program. This program has been in use during the last three years in dozens of post produc-
tion and duplication facilities. CCX has evolved into a stable and highly accurate method for
metering captions based on time code. It ensures that captions will be revealed on the
viewer’s screen at exactly the moment intended by the caption’s creator. We’ve taken our
time-tested CCX software and modified it for use in the DV2000.
DV2000’s most important feature is its ability to read caption files from the industry’s
leading agencies and caption software providers. Files from unsupported software venders
may be converted to ULTECH .ULT format and read directly. Of course, DV2000 may still
encode captions the old fashion way—by sending data to a DV2000 serial port from a PC.
DV2000 can encode on any VBI line, in component or composite format, in NTSC or PAL.
It can encode field 2 XDS data such as “V-chip” data while encoding captions in field 1.
DV2000 has an upstream digital caption decoder, so it can reencode, pass, or merge data per
EIA-608 recommendations. All of DV2000’s encoding functions are performed in software-
software that can be upgraded via ULTECH’s web site. This ensures that DV2000 will stay
current no matter what the industry may conjure up. Even DV2000’s waveform generator is
controlled via software. A benefit of this is that the caption waveform’s “0 IRE” level and its
“50 IRE” level may be set from the front panel or via script commands—no more problems
with VTR’s and converters that strip or add NTSC setup levels.

71. General Information
1.3 Character Generator
You may purchase DV2000 with an optional character generator to produce text and graph-
ics on-screen. The CG option consists of a 2.5 GByte hard drive, 120 MByte LS-120
SuperDrive, 16 MByte video RAM module, faster CPU, and associated software. The CG
provides two video frame stores of 24 bit RGB plus 8 bits of transparency (“alpha” channel).
You can create any image in 16 million colors with 256 levels of transparency over the
background video. Your image can occupy up to 512 TV scan lines in each frame. Although
the DV2000 is not intended for special effects, it is possible to create simple animations with
smooth motion—a rotating globe or a logo that grows, for example. A global fade function
allows you to fade images on and off the screen independently from transparency settings.
How to create images with DV2000 CG
The DV2000 CG can display text and graphics based on low level “drawing” commands (the
traditional method), or it can display text and graphics as individual “subpictures” (the
modern method). In both cases, the commands and/or subpictures are received via a commu-
nications port, network interface, or local script file residing on disk. Commands and
subpictures can be displayed by DV2000 based on longitudinal time code, GPI triggers, and
internal or external timing.
In drawing mode, DV2000 provides the same commands found on ULTECH’s SG401
Subtitle/Character Generator. This mode is useful for repetitive display of text such as
subtitling. Characters are rendered within the DV2000 in the specified font with the speci-
fied effects. In drawing mode, DV2000 uses the Unicode character set together with
TrueType fonts. TrueType fonts may be downloaded through any communications port, or
may be installed via disk. Version 2.26 Note: SG401 backward compatibility
In subpicture mode, DV2000 can display graphics images that are in .BMP, .PCX, .TIF, and
.PNG formats. Subpictures are loaded into a non-displayed graphics buffer then displayed at
the desired time. Subpictures are always rendered off-line, that is, on an external PC, Mac, or
workstation. You can use any graphics drawing program to create subpictures including
those from Adobe, Macromedia, MetaCreations, and many others. Subpictures can be wiped
or faded on and off the screen.
Animation is accomplished by creating a series of individual frames—perhaps dozens—that
represent the desired motion. The frames are downloaded to DV2000’s hard drive via a
network interface or 120 MByte SuperDrive, then played in sequence. Animation packages
such as MetaCreation’s Bryce3D render individual frames from key frames automatically.

2. Installation
2.1 How to connect
1. Apply source serial digital video to VIDEO IN connector. Source must be standard
SMPTE 259M video. The DV2000 terminates the source video with 75 ohms.
2. Take the program video with encoded data/text & graphics from VIDEO OUT #1 or
VIDEO OUT #2. VIDEO OUT #1 and #2 are serial digital outputs.
3. Connect VIDEO OUT #1 or #2 to Monitor Video In, a serial digital input.
4. Connect an analog composite video monitor to MONITOR VIDEO OUT or an S-video
monitor to Y/C OUT (an S-video monitor is preferred). This output is used to monitor
closed captions and to display on-screen menus when the DV2000 is in setup mode. This
output is not intended to be used as a source of analog program video. If you need analog
program video, it is recommended that you use a high quality serial digital-to-analog
video converter at one of the DV2000 program video outputs.
5. Connect longitudinal time code to the LTC In connector via an XLR-to-Mini-DIN time
code adapter cable (ULTECH part number OPT14). The LTC input can use either bal-
anced or single-ended time code with a nominal level of +4 dBu.
6. Apply AC line power to the unit via the detachable three wire cord.
Grounding (earthing)
The DV2000 must be connected to a protective earth conductor via the three wire AC line
(mains) cord. The AC power plug shall be inserted only into a receptacle outlet that has a
protective earth contact. The ground wire must not be defeated by use of a two wire exten-
sion cord.

3.3 Operating the DV2000
Power on
When power is first applied, the DV2000 will boot its operating system and will then run its
DV2000 application program. This process takes about 15 seconds. After the application
program has started, a DV2000 status screen will appear at the VGA output; nothing appears
at the monitor output other than the video source which is connected to the monitor input.
Menus
/ cursor keys
Front panel control of the DV2000 is accomplished using the cursor keys and on-screen
menus. The menus appear at the monitor output BNC and/or the VGA output. Pressing
ENTER brings-up the main menu. Pressing the left and right arrow keys brings you to other
menus. Pressing the up and down arrow keys allows you to scroll through choices within a
menu. Pressing ENTER within a menu allows you to make changes to settings. Every menu
screen has help messages to guide you.
Settings
Many aspects of the DV2000 may be customized by way of user settings. One example of a
setting is closed caption waveform amplitude—the user has the ability to set the waveform to
compensate for video sources that may, or may not, have 7.5 IRE pedestals added. Settings
are made from the front panel, or they may be done via a script file, network, or serial port.
Settings made from script files are active only while the script file is running. When the
script finishes, settings revert back to the previous settings: the ones set from the front panel,
network, or communications port. Settings may be “locked-out” from certain sources. For
example, you may prevent the closed caption line to be changed from any source other than
the front panel. You enable or disable settings in a command acceptance table that is ac-
cessed from the front panel.
The DV2000 stores all current settings on its hard drive in a file called “settings.cfg”. To
restore factory default settings, simply delete or rename this file.
Over Temperature Alarm
DV2000 contains an over temperature alarm that produces a continuous beeping if the
internal processor overheats. This could be caused by a dirty filter element, restricted air
flow, or fan failure. Operating DV2000 in an over-temperature condition will result in erratic
operation.

4. Front Panel Menus
4.1 Main Menu
DV2000 users typically deal with “jobs”, so the DV2000 menuing system is designed to
handle jobs. A job may be a closed caption encoding session, or it may be a subtitle master-
ing session. Jobs are more natural for post production users than broadcast users. In post
production, the DV2000 is used exclusively on a job by job basis. For example, in one day, a
tape duplicator may encode closed captions for two movies, and create subtitles for a third.
Each of these activities is considered a separate job. Broadcasters, on the other hand, may
use the DV2000 for real-time closed caption encoding only. In that case, they may only have
one “job” configured, and it may be named “Live Closed Captioning”.
The main menu is also referred to as the “jobs list” menu.
DV2000 has two “built-in” jobs: Load Job From Floppy and Load Job From Server. Other
jobs that appear on the jobs menu are loaded by the user. When Load Job From Floppy is
selected, files from a floppy disk (or 120 MByte SuperDisk) are copied into a unique
subdirectory under the “jobs” directory on the DV2000 hard drive. Only script, caption,
subtitle, and graphics files are copied; all other files are ignored.
If the job consists of a single caption file when loaded, the menu changes to that specific
caption job and the job is run automatically. This means an operator has only to insert a
floppy disk into the drive and select Load Job From Floppy to run an encoding job.
The DV2000 allows you to change certain parameters associated with closed captioning,
such as waveform amplitude and time code offset. When a caption job is run as described
above, the front panel settings are in effect. A user may create a script file that changes some
of the settings, then executes the caption job. In that case, the script file settings are used.

4.2 Job Menu
The job menu allows you to work with a particular job. You can run the job, cancel the job
(if it is already running), save it as another name, or delete the job. Each job resides in its
own subdirectory under dv2000\jobs. The directory has the same name as the main job file.
For example, if you load a closed caption job from the floppy or network server that contains
a single file “Blinky.cap”, a directory called “Blinky” is made: dv2000\jobs\Blinky. The
directory Blinky contains the file Blinky.cap. If you load a subtitle file called “Movie1.usf”
and associated bit map files, a directory called “Movie1” is made: dv2000\jobs\Movie1. The
directory contains the file Movie1.usf plus all of the subtitle image files.
When you delete a job from the hard drive, all of the files contained in the job’s subdirectory
are erased, and the subdirectory is removed.

4.3 CC Monitor Setup Menu
The monitor menu lets you determine which line 21 data service to monitor at the analog

choose field 2 services: CC3, CC4, T3, T4, XDS (Extended Data Services). Press ENTER to
cycle through the choices.
TIP: Choose a Text service (T1-T3) as a quick check for the presence of a closed caption
waveform—you will get a black box that nearly fills the monitor screen if a line 21 wave-
form is present.
4.4Time Code Offset Menu
DV2000 contains an internal LTC time code reader. When an off-line closed caption or
subtitle job is run, captions/subtitles are processed when time code read from the LTC input
port matches time code from the caption/subtitle file. The timing for caption/subtitle files is
established from the time code provided to the caption agency. But when the job is run, the
time code accompanying the program video may have changed. The time code offset menu
lets you adjust time code read by the internal time code reader in increments of +/- 1 frame.
The time code offset is added to the time read by the internal LTC reader. The time code
displayed in the on-screen menu reflects the sum of incoming time code and the offset.
Important Note: Caption creators
go to extreme lengths when timing
captions. You should discuss changes
in time code with the agency that
provided the captions/subtitles before
offsetting time code.
4. Front Panel Operation, Menus

20 ULTECH DV2000 User’s Manual
4.5 Com 1 Setup Menu
This menu lets you set-up the DV2000 to receive closed caption data via its Com1 RS-232
serial interface. There are two cases where you may want to send data via the serial port:
1). For live or real-time captioning, 2). To encode line 21 data from off-line service providers
that will not allow ULTECH to encode their data from floppy disk. Wherever possible,
DV2000 users should choose service providers/applications software that provide data as
files that are read directly by DV2000. This eliminates the requirement of having a stand-
alone PC drive the DV2000 via the serial port.
In an effort to support existing software, ULTECH will provide several “emulation” modes
for line 21 encoding via the DV2000 serial port. The current version of DV2000 software
provides compatibility with the ULTECH Insertacap. This mode offers both field 1 and field
2 encoding for Captions, Text, and XDS Extended Data Services. You may obtain a
programmer’s reference by contacting ULTECH. Nearly every real-time and off-line applica-
tion can be handled in Insertacap emulation mode. In the near future, ULTECH will provide
an emulation mode for the EDS400 Encoder. Among other things, this will allow the merg-
ing of TV Crossover Links with upstream data, and the merging of locally inserted XDS data
with upstream data.
In this menu, you can set the baud rate to 1200, 9600, 19.2K, 38.4K, 57.6K, and 115.2K bits
per second. You can also choose between 8 data bits, no parity, 1 stop bit, or 7 data bits, odd
parity, 1 stop bit. Please consult your applications software manual for the preferred settings.
