The PCE-845 is a Closed Caption Encoder for Inserting Caption and Text data on line 21 of the
NTSC signal. The PCE-845 will insert four channels
of data that are multiplexed into the vertical interval
on line 21 of field one. The four channels of line 21
are described as Caption Channel One, Caption
Channel Two, Text Channel One, and Text Channel
Two.
The PCE 845 also processes data on Line 21 of field
two to meet the new revised FCC specifications. To
meet future requirements, the PCE 845 is capable of
inserting data on lines 10 through 25. A single
internal jumper selects correct line placement. The
unit is compatible with PAL closed caption, and
caption data is usually inserted on Line 22 of field
one. Line voltage operation is recommended for
115/240VAC, 50/60Hz, internally selected. The input
signals are composite video, S/VHS, or Y, R-Y, B-Y.
There are two composite video outputs. If a
component format is used, the delay of each signal
path is carefully matched, providing transparent
thru-put. An RS-232C Input/output data port is
provided on the rear panel that operates from 600
to 4800 baud (jumper selected). A second data
port can accommodate an external modem. A
switch on the front panel labeled "TEST" places a
test message on line 21 to confirm proper
operation of the encoder. A modem and computer
can be connected to the PCE-845 simultaneously
to receive local and remote caption data.
Two front panel LED's indicate the operation in
field one or field two. Other status indicators
confirm the presence of input video and RS-232.
By-pass mode may be selected from the front
panel, by software commands or via remote
control. By-pass is transparent, and will not glitch
the video signal when selected.
