This article is a little bit misleading because it's not really copy protection.<p>The BBC aren't allowed to encrypt content at all but they're proposting to encrypt only HD content over DVB-T2, known as Freeview (OTA for Americans).<p>There's two things which they're asking for (feel free to correct me if the transport stream technicalities are wrong).<p>Obfuscation of the service information data with a huffman code lookup table. The SI allows transport stream demuxers to work out how to split the transport stream up with information like video types, audio tracks, clock info etc...This can all be worked around easily.<p>The other is full encryption which won't be allowed because it will delay set top boxes and there won't be any on the shelves during the World Cup, which is basically an HD flagship event.<p>There's no encryption on satellite nor on cable anyway so it's a bit of a moot point.
