Video Inputs
The HD or SD program video source should be connected to the
PGM IN A
BNC. If you are using the
7825DSK2-LG(-HD)(-3G) as a two input standard definition video keyer, the alternate video source
should be connected to the
PGM IN B
BNC. If you are using a downstream key source for the
downstream keyer, the Key video should be connected to a
KEY 1 IN
or
KEY 2 IN
BNC and the fill
should be connected to the corresponding
FILL 1 IN
or
FILL 2 IN
BNC. The 7825DSK2-LG(-HD)(-3G)
supports HD or SD digital video in the formats shown in Table 2-7. The video standard must be set
manually to match the incoming video type (see section 4.2.1 for VLPRO Configuration and section
5.6.1 for RCP Configuration).

Table 2-7: Video Input Formats
2.5.2.
Video Outputs
The
PROG OUT
output contains the video output from the Program Bus and should be connected to
the main broadcast chain of your facility. The
PROG OUT
output is protected by a bypass relay. When
the relay is active, the
PROG OUT
output is directly connected to the
PGM IN A
input.
The
PREV OUT
output contains the video output from the preview and will normally be connected to a
HD/SD monitor to allow you to view the program output before it goes on air. When the bypass relay is
active, the
PREV OUT
output will not have any video on it.
2.5.3.
Genlock Reference
For proper switching of the video and audio signals an analog video genlock reference must be
supplied. Connect a composite analog NTSC or PAL colour black video signal to the GENLOCK
connector. Make sure that the signal type is correct for the video standard in use. (See Table 2-7)
