What are RCE, CSS, RPC, RPC-2 or Macro-Vision ?
Eight leading film companies in the USA added CSS (Content Scramble System) into DVD format for anti-piracy of digital duplication. Furthermore, Macro-Vision was extra-added to prevent analog devices piracy. Due to the different broadcasting time of DVD film in the various regions in the world, they wouldn’t want a DVD film sold in one region then transported to another which has not been released, the eight major film companies divided the world into 8 regions (see table below). They got all DVD disc and DVD playback devices embeded with specific regional code which must match the region, the film can be played. This is called RPC (Regional Playback Control). However, the three methods of protection have been hacked. There have been many region-free discs and players in the market. Again, the eight leading film companies developed new technology RCE (Regional Control Enhancement). Region-free DVD-ROM or DVD player can’t play disc with RCE technology. RPC-2 is designed only for DVD-ROM
