four French national channels that decided to recently made the leap to high-def? Yeah, well those four are the first HD terrestrial TV channels to implement Dolby Digital Plus. In fact, both Dolby Digital Plus and Dolby Digital were chosen by those broadcasters for the Television Numerique Terrestre platform, and viewers tuning into TF1 HD, France 2 HD, ARTE HD, Canal+ HD and M6 HD will be able to listen to 5.1-channels of audio so long as they have the requisite decoding equipment. Interestingly enough, the French HD forum specification "requires that by December 2008 HD-ready TVs for sale in France must include Dolby Digital Plus and High Efficiency AAC (HE AAC) audio." Atta way to be proactive, France!
