This repository contains simple GNU Radio Companion scripts that I have used for simple DVB setup. It's no DVB-T or DVB-S system (yet), just a simple way to get a webcam on the air.
-For video processing I used Gstreamer and connected to GNU Radio using named pipes. See http://wiki.oz9aec.net/index.php/Simple_DVB_with_Gstreamer_and_GNU_Radio for more details.
