This was apparently repeated several time on different channels on Sunday but so far the Chinese government has imposed a news blackout on the incident. However thanks to the Internet and the millions of witnesses, word has leaked out. Surprisingly, security on satellites can be very weak - often transponders are left on when not active and will continue to rebroadcast whatever is beamed at them. It's believed that Falun Gong used a 3 meter dish antenna mounted on a vehicle to overpower the government's uplink signal. This is not the only time that satellite signals have been hacked - there was the famous 'Captain Midnight' incident in 1986 and it's believed that Iraq has been attacking Kurdish satellite tv channels for several years. Hackers have even (discreetly) made use of the U.S. Navy's FleetSatCom satellites."
