Having written about video and audio technology sincegulp!1980, let me tell you, there have been some mighty dull years. When I started out, big- screen TVs existed, but were based on analog technology and looked awful. The notion of combining video and audio into a single system was so unusual then that I was actually rebuked by my bosses at Video Magazine for writing a long and prominent new- product item about the very first surround receiver. It was a Kenwood with composite video switching, and no surround decoding, because surround sound hadnt reached the home front. HDTV and the progeny of Dolby and DTS have remade the world and made it better. Now you can enjoy a huge, detailed picture with sound all around you. And just when you think things couldnt get any better, theyre about to. Again. Here are a few rash predictions for 2007.
