    "abstract": "A new system of Digital TV broadcasting by satellite was launched in Japan in December 2000. With this system, 5.1 and 3–2 multichannel sound programs can be broadcast. Many 3–1 multichannel sound programs have already been broadcast with HDTV, and various experimental recordings of 3–2 multichannel sound have been conducted at NHK. Multichannel sound opens a new dimension of sound production in television. It also confers substantial advantages in sound reproduction such as spatial impression and sound source localization in a horizontal plane. But it is also true that multichannel sound production is much more complicated than ordinary two-channel stereo recording.",
