Instruction manual

HDE-3000 - 96 -
New Feature: New menus.
To allow the HDE3000 to encode, decode, filter, and multiplex EIA-608 captions new
menus had to be added to the HDE3000. The “EIA-608 SETUP MENU” menu allows the user to
control EIA-608 encoding and filtering. The “CC LEVEL and POSITION SETUP MENU” menus
allow the user to control the amplitude, vertical offset, and horizontal offset of the EIA-608
caption waveform encoded into line 21 for NTSC and line 22 for PAL.
New Feature: re-direct “encoded” caption data
New options were added to the COM port setup menus in the HDE3000 software: The
following new options were added: ENCODED F1, ENCODED F2, and ENCODED F1+F2.
These options instruct the HDE3000 to transmit all “encoded” EIA-608 data out the serial port.
This is also termed the “downstream” caption data. This data is the caption data
encoded/multiplexed into the output video of the HDE3000.
Correction: fixed EDS400 emulation problems
To encode serial caption commands (“control A” commands) , the HDE3000 serial ports
can be configured to “emulate” the ULTECH EDS400 analog caption encoder. The serial
command processor used to emulate the EDS400 serial caption commands had some problems
related to the ability to encode two languages of captions simultaneously.
Correction: fixed EIA-608 decoder
There was a bug in the EIA-608 decoder in the HDE3000 Remote program (the
application that displays status, menus, and captions on the VGA monitor). The bug caused
incorrect display of roll-up captions when they appeared at the top of the display.
Version 1.24
Experimental version not released
Version 1.25
New Feature: Open Caption Decoder.
An “open caption decoder” is a device that decodes closed captions and overlays (or
“burns”) the caption characters into the video. The HDE-3000 allows you to monitor the closed
captions on the VGA monitor. This new feature allows you to “burn” the open captions into the
program video. This feature uses the subtitling hardware in the HDE-3000 to “burn” the
captions into the program video as if they were subtitles.
Enhancement: Pass Special Characters in Newswire mode.
The EDS400 emulator was enhanced to pass EIA-608 “special character” control codes
when in the “newswire” mode. The “newswire” mode is entered using the “control-A 2” serial
command. The EDS400 emulator will now recognize special character control codes, force
them to be correct for the current channel (CC1, CC2, etc.), and encode them.
