Economist and blogger Nobuo Ikeda writes about a prominent idea [ja] to introduce the “dubbing 10″ system, abandoned only weeks ago, though an airwaves encryption scheme. Ikeda explains that the idea would be to pair a key to the encrypted airwaves with the dubbing ten system, which he claims is illegal as it would violate Japan's Antitrust Act. To control the copying of freely-distributed broadcasts (as dubbing ten would do) moreover also goes against Japan's Broadcast Law, Ikeda argues, pointing out that nowhere else in the world has any country attempted this sort of thing.
