Evaluation of HDTV Closed Circuit System for Distance Education

Abstract

Tokyo Institute of Technology has been transmitting TV lectures and TV conferences to both the O-okayama and Nagatsuta campuses through optical fiber cables. In January 1989, the lectures were transmitted using fine-quality HDTV with optical fiber cables in order to make an evaluation.
The factor analysis results show the “quality of the image”, the “atmosphere of the lectures”, the “screen”, and the “sound”.
Compared to the NTSC system, the high-definition system was evaluated based on the purposive differentials of 5% level of significance for the “atmosphere of the lecture”, and 1% level of significance for the “projected quallity of image”. There has not been any specific purposive differential for the “screen” and “sound”.
These results indicate that HDTV is very effective for distance education.
