ipod 関連製品をクライアント機として利用するモバイルサーバ発信の動画 音声試験の考察 名古屋学芸大学教養 学際編 研究紀要第 8 号 2012 年 2 月 ipod 関連製品をクライアント機として利用するモバイルサーバ発信の動画 音声試験の考察 A Study on Testing with Movie or Voice Aids through a Mobil Server, Utilizing ipod Products as a Client Machine Tadashi ANDO SUMMARY In the previous research bulletin, I introduced the utilization of a mobile server for a text- and voice-based examination, but in the present article I would like to study on the introduction of a video-based exam on a mobile server. In this regard, I have tried to let the students to make some comments in the dialogue box of the website screen freely and evaluate what they wrote. Moreover, I also focused on employing the Apple related products such as ipad, iphone and ipod touch which recently are in widely use among youngsters like university students. There are some problems, however, in utilizing those apple related products for an exam by videos because most ordinary video file extension formats such as.avi,.wmv, pm3, flv.mov, etc., that are commonly used on PCs, are not compatible for Apple related products. As far as I have tested and practiced, only mp4 file extension format can be activated on the Apple products. I, therefore, had to convert all the video formats from the Windows OS mobile server into mp4 extension, so that the video can be activated on the website of all Apple related products. What I wish to research here is the mechanism relating to the relevance of a certain type of a file extension format between Windows PCs and Apple related products. I have deeply surveyed the computer program system in relation to this kind of extension format for the website, describing its HTML tag program in order to activate the videos on the related website with no problems and interference. 159
