G-Series Reference Manual 166
13.1 Video overview
The G-Series system is supplied with S-Video cabling but you can
also use composite video devices. Video processing is handled by
a GVM400: each of these devices provides four inputs. The total
number of video inputs available depends upon your system
configuration.
The system can handle multiple video inputs, and you can cycle
through the attached devices to stay updated on each view.
You can also adjust the brightness, contrast, color and aspect ratio
of the image, adjust audio volume, and set a video window to dis-
play a mirror image of the feed (see
page 167).
13.2 Setting up the video application
Before you can use the video application, you may need to config-
ure a page set to include a video application window. For
information about how to do that, see
page 25.
At installation, the video module (GVM400) or modules attached to
your system, along with any video input devices, were named. You
can change these names if you wish.
Customizing the video application
You need to change the default settings in the following
circumstances:
• To use composite video on input 1.
• To name video inputs (for example ‘engine room’, ‘view stern’,
‘DVD’, etc).
• To cycle video views.
• To set up the selection softkeys.
All these options are accessed from the Video Setup Menu.
To open the video setup menu
1. With a video window active, press the MENU button.
2. Select Video Setup Menu.
3. Press OK.
13.3 Using composite video on input 1
By default, the system allows for one S-Video input (input 1) and
three composite video inputs (inputs 2-4). If you want to use input 1
for composite video, you need to change the video input settings.
To change video input settings
1. Open the Video Setup Menu.
2. Select Composite.
3. Press OK.
13.4 Setting a name for the video feed
By default, the video sources are labelled ‘Comp1’ to ‘Comp3’ and
‘S-Video’. You can change these labels to make them more
descriptive, for example: ’engine room’, ‘stern’, or ‘bow’. You can
also rename each video controller module (GVM).
To edit the video feed name
1. Open the Video Setup Menu.
2. Select the video source whose name you want to change.
3. Select RENAME.
4. Change the name and press OK to save the changes.
13.5 Selecting a video input
To change choose a video input to display, press the appropriate
softkey. If you have more than four video inputs, press the rotary
controller to open a list of all video feeds available and then select
the one you want to use.
