Picture-in-picture mode
The DVS 304 can display two image sources on the screen simultaneously. Keep in mind
that when using the PIP feature, one image source must be low-resolution (composite,
S-video, YUVi and RGBcvS) video, while the other must be high resolution (YUVp/HDTV,
RGB scaled, SDI) video. If these conditions are not met (for example, two low resolution
video inputs or two high resolution inputs are selected), the PIP mode will exit.
To go into picture-in-picture mode, do the following:
1. Select an input for the main window.
2. Define the size of the main window before starting PIP mode.
3. Activate the PIP mode via an SIS command or IR remote; specify the PIP window input.
DVS 304 checks the input format for the PIP window and returns an error message if an
invalid selection is made.
NOTE: For quick sizing setup, use the 16*# X10% SIS command to set different sizes for
the PIP window.
When the PIP mode is active, note the following:
• The LED for the main window input is ON.
• The parameters of the PIP window are adjustable from the front panel or by SIS
commands only.
• Any change in configuration (except positioning) of the PIP window is saved to that
input even after the PIP mode is not longer active.
• The PIP window input is listed under the default cycle on front panel menu, as shown
below.
When the PIP window is active, size, position, and picture controls all apply to the PIP
window. The main window settings cannot be modified while the PIP window is active.
The PIP size and position can be adjusted with the same front panel controls or SIS
commands used to adjust the main image.

Figure 22. PIP Sequence
If the PIP window source is not active, the PIP mode exits until an active signal is detected.
When the main window source is removed, a black background is displayed.
Changing the input
To change the input for the PIP and/or main window, determine if the corresponding input
is a low or high resolution.
If your main window image is from a low resolution source, switch to another low
resolution input from the front panel.
