Abstract
As a part of information barrier-free promotion, Nippon Television Network Corporation developed the real-time closed caption broadcasting system by connecting with stenographic word processing company. We developed various mechanisms such as automatic caption speed control mechanism, a quasi-scroll mechanism, and automatic caption cut mechanism in CM insertion period. By those mechanisms, this system became a very practical system. We started the first real-time closed caption broadcast in Japan in the news program "News Dash" from August 27, 2001 by using this system.
