  • Page 5: General Information

    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.

  • Page 6: Closed Caption Encoder

    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.

  • Page 7: Character Generator

    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.

    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.

You respond to GPI triggers from within a program script. Likewise, you can generate GPI triggers from a script, perhaps based on certain time codes.

  • Page 15: Operating The Dv2000

    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.

    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.

  • Page 18: Job Menu

    (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”...

  • Page 19: Cc Monitor Setup Menu

    Help messages 4.4 Time 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.

  • Page 20: Com 1 Setup Menu

    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).

  • Page 21: Safe Title Area Menu

    You can set the safe title area pattern to several colors and transparencies by cycling through the color menu. ULTECH also provides a useful graticule for taking mea- surements of on-screen items in terms of DV2000 coordinates. The graticule is a graphics file called TestGrid.uyc and a related script file: TestGrid.scr.

  • Page 22: Cc Level Setup Menu

    ULTECH DV2000 User’s Manual 4.7 CC Level Setup Menu DV2000 allows you to adjust the “data bit low” level and “data bit high” level of the en- coded closed caption waveform. Normally, the adjustment is made such that data bit low produces a 0 IRE level, and data bit high produces a 50 IRE level.

  • Page 23: Cc Waveform Position Menu

    4. Front Panel Operation, Menus 4.8 CC Waveform Position Menu DV2000 allows you to adjust the location of the closed caption waveform with respect to the timing reference code embedded in line 21. The factory default positions the waveform in exactly the correct location per the recommended practice.

    DV2000 software version does not set these flags. Internal Device Error Detected Already This flag is passed from input to output by the DV2000. The DV2000 ignores this flag, although you can view the flag in the EDS Status Menu.

  • Page 27: Script, Caption, And Subtitle Files

    5. Script, Caption, and Subtitle Files 5.1 Introduction The DV2000 is able to read and encode closed caption files in a number of formats. Like- wise, it can read subtitle files and associated “bit mapped” image files to produce open subtitles.

Time code is either read externally or is simulated with the DV2000’s internal clock. If you are using simulated time code then you must precede the first WaitUntil com- mand with a SetTime command.

  • Page 30: Caption Files

    .TDS ULTECH .ULT The caption files may be loaded into the DV2000 via the front panel floppy drive, network interface, modem, or serial port. The ULTECH caption file format (ULT file) is a compact binary file that stores captions with embedded EIA-608 control codes and time code data. It was designed as a fast interme- diate file format for CCX and the DV2000, not for general purpose caption creation.

  • Page 31: Subtitle Files

    In the DVD world, subtitle script files are known as “navigation” files. The DV2000 uses a simple file format that is opti- mized for subtitling. Files in this format have a file extension of “.usf”, and are therefore referred to as “USF”...

    YC format. A future version of DV2000 software will convert all of the popular formats to YC format as the files are transferred to the DV2000. The current version of software requires a separate conver- sion step on a PC using graphics file converters supplied by ULTECH.
  • Page 33 PNG, pronounced “ping”, is the format recommended by ULTECH for use with the DV2000. PNG files are compressed, so they require less disk space than the other formats. Plus, PNG offers a full alpha channel. Unlike 32 bit BMP, PNG files are handled by Adobe Photoshop, a leading graphics creation and editing program for the Mac and PC.

  • Page 34: Uyc File Format

    Because of this, the first displayed video line overlaid by the DV2000 CG is line 23 (lines 1 to 22 are overlaid by the VBI waveform generator and lines 23 to 262 are overlaid by the character generator). Since the DV2000 performs image processing on a field by field basis, the Y offset parameter can only be between 23 and 262 inclusive for NTSC (40 - 295 for PAL).
  • Page 35 Reserved for future use (always zero) Signature 0, 1 These two words are used by the DV2000 to indicate that this file is a UYC file. The words are arranged so that when a UYC file is viewed with a hex editor the first four bytes appear as “UYC<space>”.
