HDE-3000 - 10 -
IMPORTANT! The HDE-3000 is a sophisticated piece of video equipment.
Never think of or use an HDE-3000 as if it were a standard desktop PC. Do not install
any software, update any operating system components, or apply any service packs
intended for “normal” Windows XP. Doing so may cause the HDE-3000 to malfunction,
will void the warranty, and will require the operating system to be re-installed at the
factory.
IMPORTANT! Always shut down the HDE-3000 using the “shut down” menu and
wait for the front panel LED’s to go out before turning off the power via the front panel
“soft power-off” switch. Never turn off the power without executing the “shut down”
menu unless absolutely necessary. Turning off the power to the unit while it is running
may cause damage to the file system on the hard disk which can only be repaired by re-
installing the operating system at the factory.
1.3 Closed Caption Encoder
HDE-3000’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 .ULT format and read directly. Of course, HDE-
3000 may still encode captions the old fashion way, by sending data to a HDE-3000
serial port or network interface from a PC. HDE-3000 may also encode “live” caption
data via an optional internal or external modem. HDE-3000 encodes captions into the
VANC portion of the stream using the latest SMPTE standards.
1.4 Graphics Inserter
HDE-3000 comes standard with a full screen, full color graphics inserter (GI).
The GI 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 the full screen of all
HD formats, including wide screen. A global fade function allows you to fade images on
and off the screen independently from transparency settings.
How images are displayed with HDE-3000 GI
The HDE-3000 GI displays text and graphics in a special format known as “UYC”
format. Link provides file converters to convert from BMP, TIF, and PNG formats to
UYC. Sub-pictures are loaded into a non-displayed graphics buffer then displayed at the
desired time. Sub-pictures are always rendered off-line, that is, on an external PC or
Mac. You can use any graphics drawing program to create sub-pictures including those
from Adobe, Macromedia, Jasc and many others. Sub-pictures can be faded on and off
the screen.
Link also has an optional drop and drag graphic software that will convert the
images for you and write the script file that controls the graphics inserter. The program
can also be used to remotely insert graphics.
