地上デジタルテレビ放送(地デジ)

With digital TVs, viewers can enjoy quality images and sound of high-definition broadcasting. The digital TV also provides various other functions to its users, such as allowing them to look at the broadcasting schedules on the screen or check the latest news and weather forecasts. In Japan, digital broadcasting started in 2003 in some areas, including the Kanto region. The nationwide transition to terrestrial digital broadcasting, referred to as chideji, is scheduled to be complete by July 24, 2011.

The switch to digital broadcasting has been a global movement as well. For example, analog broadcasting was concluded before the end of 2009 in seven European countries including Sweden and Holland. A complete transition to digital broadcasting is scheduled in Germany, France, and England. Some countries in Asia and South America have also decided to follow this change.

There are a variety of types of chideji-compatible TV sets now available on the market, from those with giant screens ideal for home theater to small portable TV’s. Viewers may also enjoy digital programs by installing a chideji tuner and UHF antenna to a current analog TV or a computer. Some customers of cable broadcasting may also continue to use their existing analog TV set to receive chideji service.

However, according to a survey conducted by the Ministry of Internal Affairs and Communications, the prevalence rate of chideji receivers has reached only 60.7% as of March 2009, requiring the government to further promote a nationwide campaign for advancing the transition to digital broadcasting. The websites below provide a variety of information regarding terrestrial digital broadcasting in Japan.
