5.2 Caption Files

Currently, DV2000 can read caption files in the following formats:
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. As a
result it is not readable by a text editor. CCX is ULTECH's Windows-based encoding
software that is used to drive analog encoders and character generators manufactured by
ULTECH.
Note: The .ULT file must contain captions that have the appropriate control codes embedded
with the text. Also the time code for each caption should be equal to the desired appear time.
DV2000 does not adjust the caption appear time.
The .ULT file format supports multi-stream captions. Multi-stream captions allow multiple
data channels to be encoded at the same time. For example, bilingual captioning: English on
CC1 and Spanish on CC2.
A software development kit is available from ULTECH that includes a full specification for
the .ULT format together with sample source code and data files.
