If your DVB card has a fullscreen OSD mode (some only support a limited number
of very small OSD windows), you can write a frame buffer device for the OSD
plane. Then you can have a text console, X, links2, ... in the OSD plane, and
video in the video plane underneath (controllable through an alpha/transparency
parameter).

This is a common approach in Set Top Boxes.
