DEF CON 30 - Karl Koscher, Andrew Green - Hack the Hemisphere

The Shadytel cabal had an unprecedented opportunity to legally uplink to and use a vacant transponder slot on a geostationary satellite about to be decommissioned. This talk will explain how we modified an unused commercial uplink facility to broadcast modern HD DVB-S2 signals and created the media processing chain to generate the ultimate information broadcast. You'll learn how satellite transponders work, how HDTV is encoded and transmitted, and how you can create your own hacker event broadcast.
