BS digital broadcasting began service on December 1st, 2000 via broadcasting satellite. Terrestrial digital broadcasting started exactly three years later in the Tokyo, Osaka and Nagoya areas. Ground-based broadcasting has since been steadily shifted to cover regional stations across Japan by December 1st, 2006. The format gives viewers access to high-picture-sound-quality high definition TV programming, as well as realizes interactive service, and allows them to withdraw various information, including news and weather forecasts. Using an electronic program guide(EPG), viewers could also program recordings.
Meanwhile, the so-called One-Seg terrestrial digital broadcasting service for mobile phones and other mobile devices also kicked off in April 2006.
Digital broadcasting allows distribution of high-quality moving images with no motion-related interference to TV screens installed in moving cars, trains and buses as long as signals could reach the medium. |
