2.5. CONNECTING THE VIDEO
2.5.1. Video Inputs
The HD or SD program video source should be connected to the PGM IN A BNC. If you are using the
7725DSK-LG 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 the KEY IN BNC and the fill should be connected to FILL IN
BNC. The 7725DSK-LG-HD supports HD or SD digital video in the formats shown in Table 2-6. The
video standard must be set manually to match the incoming video type (see section 3.2.1 for VLPRO
Configuration and section 4.6.1 for RCP Configuration).
"
Note: In order for the 7725DSK-LG-HD to operate in SD mode, the user will be
REQUIRED to download SD only firmware to the mode. The 7725DSK-LG-HD DOES
NOT auto-detect the video format.

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 plant. 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 REF IN
connector. Make sure that the signal type is correct for the video standard in use. (See Table 2-6)
