抄録: 太陽光発電システムを電源とする、通信衛星を用いた教育用テレビ放送受信システムの設計開発と放送実験について論じた。ビデオテープ上に録画した放送番組を日本から発信し、タイ国のミャンマー国境近くに位置する山岳少数民族集落で受信し、そこに居住する成人ほかに視聴してもらった。番組は「薬草」と「衛生」に関するものである。実験は2001年3月3日、4日の両日、現地時刻18:00~20:00 で実施した。放送番組は実験サイトにおいて、極めて高品質で受信できた。放送中の視聴者たちの表情を観察した。放送後、受信サイトの成人と子供に対しテレビ視聴の経験と番組の視聴について簡単なヒアリングを実施した。本研究で用いた受信システムは開発途上国における僻地教育の支援、国際間の教育支援に有効な手段の一つとなりうるであろうと結論した。 / A television (TV) broadcast receiving system through communication satellites for educational objectives has been developed. The system has solar modules to generate electric power and the electricity obtained will then be supplied to the receiving system of the TV programs. The TV programs were recorded on videotapes in Japan in March 2000 before the receiving experiment. The programs were sent from Japan through the satellite PanAmSat Pas 4 and they were received at the experimental site located in a remote place,Ban Nong Pha Jam Mai in Mae Hong Son Province, a hill-tribe village on the Thai side of the border area between Thailand and Myanmar. The experiments were carried out during two days on March 3 and 4, 2001 at 18:00 till 20:00 (Thai local time). The Thai TV programs were also received at the same site via the satellite Thaicom. The quality of the TV programs we have received at the experimental site has been very good in terms of picture,voice, and text characters. We have observed the expressions of the persons, both adults and children, who had watched the TV programs at the site during the experiment. After the receiving experiments we performed a hearing survey of the impression those who watched the TV programs formed of them. From the results of observation and hearings we have concluded that most of the persons who watched the TV programs formed good impressions of them. This TV receiving system is one of new approaches to getting the TV programs at the place where there is no commercial electricity supply, and this system will be expected as one of the procedures to solve the difficulties of the educational problems at remote regions in developing countries. The present system is not expensive, easy to install, and easy to maintain.
