The caption encoder will have a rear panel that closely resembles one of
the four depicted in Figure 2-1 to Figure 2-4. The following sections
describe the purpose of the rear panel connectors and describe the
specific signals that should be connected to the encoder.
2.1.1
Program Video Connections
SDI IN:
A BNC connector for input of 10 bit 4:2:2 component serial
digital video signals compatible with the SMPTE 259M standard.
SDI BYPASS OUT:
component serial digital video signals compatible with the
SMPTE 259M standard.
identical to the input video data, with caption data inserted onto
it. When the bypass relay is activated (on power failure or by
closing the Bypass GPI to ground) the SDI BYPASS OUT is a
direct relay connection to the SDI IN.
FAULT TALLY OUT: A BNC connector for output of a SMPTE 269M fault
tally.
The output will be open circuit when the 8084 is
processing video normally. The output will be grounded when
the unit is bypassed.
Revision 1.6.6
A BNC connector for output of 10 bit 4:2:2
The video data will normally be
