HDE-3000 - 28 -
EDS400 Emulation
This enables the emulation of the commands and functionality of the EDS400.
The EDS400 is able to merge local caption data with upstream data, as well as multiplex
locally inserted XDS data with upstream data. You can read time code in EDS400
emulation mode by way of the serial port.
You can set the baud rate to 1200, 9600, 19.2K, 38.4K, 57.6K, and 115.2K bits per
second on this menu. You can set the port parameters to 8-none-1
(Sets the Com
1 serial port to 8 bits, no parity, 1 stop bit) or 7-odd-1
(Sets the Com 1 serial port to 7
bits, odd parity, 1 stop bit) on this menu. Please consult your applications
software manual or your caption provider for the preferred settings.
The parser mode parameter is used to tell the HDE-3000 how to interpret the data
being received on its serial port. There are five possible settings for this parameter:
1. In “NORMAL” mode, the HDE-3000 expects “normal” caption encoder
commands (also known as “control-A” commands) as transmitted by typical
caption authoring and encoding software.
2. In “BRIDGE ULT F1” mode, the HDE-3000 expects raw EIA-608 field one data,
and it encodes all of this data verbatim, directly into EIA-608 field one.
3. In “BRIDGE ULT F2” mode, the HDE-3000 expects raw EIA-608 field two data,
and it encodes all of this data verbatim, directly into EIA-608 field two.
4. In “BRIDGE ULT F1+F2” mode, the HDE-3000 expects raw EIA-608 data for field
one and field two, and it encodes all of this data verbatim, directly into EIA-608
field one and field two. To distinguish the field one and field two data, the HDE-
3000 expects the data to be formatted as follows. First a “sync byte” (hex 0x80,
decimal 128), then two bytes of EIA-608 field one data, then two bytes of EIA-
608 field two data. Note that for this mode to work properly, the format must be
set to “8-none-1”
