To create a picture in picture or picture with picture layout complete these steps in the VGA Grid's web
interface:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface .
2. Login as admin.
3. Ensure at least two video input sources are connected to the VGA Grid HD Encoder.
4. From the web interface, click Encoding for the encoder's channel; the Encoding page opens.
5. Scroll to the DVI channel section.
6. Check the Enable DVI channel check box.
7. Scroll to the Video channel section.
8. Check the Enable video channel check box.
Channel source layout is not available if Enable video channel is unchecked.
9. Select a Picture in Picture layout to specify how each input source (DVI or VGA and S-video) is streamed.
Hardware limits the position of the S-Video picture to align with a multiple of 32 pixels. As a
result, it's possible there is a small gap between the DVI/VGA and S-Video streams, or that the
S-Video stream is not perfectly right-aligned when superimposed over the DVI/VGA stream.
