Outline of ARIB



Establishment: merge of two organizations in 1995:
 Research & Development Center for Radio Systems (RCR)
 Broadcasting Technology Association (BTA)
Objective: promotion of pubic welfare by means of:
 conducting investigation, R&D and consultation of utilization of radio
waves
 promoting realization and dissemination of new radio systems
Main Activities:
 investigation and R&D on utilization of radio waves
 establishment of voluntary technical standards for radio systems
 consultation, dissemination, collection and publication of information on
utilization of radio waves
 frequency change support for terrestrial digital TV broadcasting
 frequency expiration support for re-allotment of radio spectrum
