Karl Koscher and Andrew Green: Hack the Hemisphere — Hacker Satellite Broadcasting

A DEF CON 30 talk about an unusual experiment with satellite communications. After obtaining legal access to an unused transponder on a geostationary satellite about to be decommissioned, the researchers used it to broadcast their own signal.

The talk explains how a commercial uplink facility was modified, how an HD video transmission chain was built using the DVB-S2 standard, and how satellite television broadcasting works.
