Terrestrial TV broadcasting will be discontinued in July 2011. However, in the case
of radio, existing AM, FM, and SW analog services are expected to continue, thus
digital radio is being positioned as an opportunity to provide more channels.

At present, digital radio broadcasting is operated by a consortium where
corporations interested in digital radio broadcasting have participated. The official
name of the consortium is a corporate judicial body called the Association for
Promotion of Digital Broadcasting or the DRP (Digital Radio Promotion) for short.
The establishment of the consortium was permitted by the Ministry of Internal
Affairs and Communications. The DRP has two offices, in Tokyo and Osaka. The
operation fund is provided by the member companies. Members include NHK,
radio stations, TV stations, data broadcasting companies, trading companies,
automakers and other companies interested in digital radio in the private sector.
Over 70 organizations and companies have joined the consortium throughout
Japan.
The objectives of the DRP are as follows:
• Implementation of experimental broadcasting for practical application
• Development of broadcasting services
• Research and study on trends in demand
• Promotion and spread of reception

The DRP is the only corporate judicial body licensed. Its experimental stations are
located in Tokyo and Osaka. The broadcasting facilities are owned and operated
by the DRP.
