Recently my interest in digital video broadcasting was tickled, so I started reading about it again. With television I usually have this 'the technical side is interesting but the content is not interesting' opinion so I am not going to buy a satellite dish at home yet. My ideas on what I want to play with and where are now documented at my DVB experiments page. I did order a simple free-to-air capable dvb-t usb stick so I can play with it. When I get bored with the subject again it's still a way to get some TV news should the cable fail or on the road.

Making those maps for the DVB experiments page was quite a bit more work than expected. I hoped to simply use openstreetmap maps and put some extra points in those but that was harder than expected. I tried gpsdrive but it can't just download openstreetmap street maps. It does have some openstreetmap support but if I get it correctly I'll have to install the whole mapnik program suite first. I skipped that for now. What I did was download maps from openstreetmap using gpsmap from kismet and import those in gpsdrive. Well, the gpsdrive import did not work correctly but I just put the right numbers in map_koord.txt. The waypoints for the transmitters al came from the German Bundesnetzagentur. Being very German and therefore very gr√ľndlich (thorough): they list all the active DVB transmitters for all surrounding countries, even where the chance of actual interference is quite small, like Den Burg on Texel in the Netherlands or Viborg in Denmark. With the maps with the transmitters as waypoints shown in gpsdrive I made some screenshots used on the page, with some lightbox 2 sprinkled on top for nice viewing.
