This repository contains simple GNU Radio Companion scripts that I have used for a simple setup for digitsal video transmission. It's no DVB-T or DVB-S system, just a simple way to get a webcam on the air. For video processing I used Gstreamer connected to GNU Radio using named pipes. See http://wiki.oz9aec.net/index.php/Simple_DVB_with_Gstreamer_and_GNU_Radio for more details. gmsk_tx.grc and gmsk_rx.grc: A simple GMSK transmitter and receiver pair that can be used on separate computers and USRPs. gmsk_trx.grc: A smiple GMSK transceiver that can be used on one computer with one USRP for both transmit and receive. gmsk_sim.grc: A simple TX+RX simulator that can be used to test without any USRP. gst-cmd.txt: Example Gstreamer commands to build the video processing pipelines. multicam.py: An experimental GUI to switch between different cameras (not very functional yet). Note that recent versions of GNU Radio now include a digital television package that is capable of making DVB-T and DVB-S/S2/S2X compatible transmissions.
