In this method, students watch the video of the blackboard based lecture on a tablet computer. Some parts of the blackboards are recorded by two or more cameras, and a player is designed to enable the students to view and listen to any portion of the lecture. The videos in our method must be high resolution and high quality so that students are able to identify the characters written on the blackboard. However, when many students receive the video by wireless LAN, the bandwidth available for each student decreases. We attempt to maintain the image quality of the video by decreasing the frame rate. After viewing the videos, the tested students have completed questionnaires to evaluate these videos.<\/p>","DOI":"10.4018\/ijtem.2014070103","type":"journal-article","created":{"date-parts":[[2014,10,6]],"date-time":"2014-10-06T14:46:00Z","timestamp":1412606760000},"page":"28-42","source":"Crossref","is-referenced-by-count":0,"title":["The Distribution Method of the High Resolution Video for a Blackboard Based Lecture"],"prefix":"10.4018","volume":"4","author":[{"given":"Shinnosuke","family":"Yamaguchi","sequence":"first","affiliation":[{"name":"Kyushu Institute of Technology, Iizuka-shi, Fukuoka, Japan"}]},{"given":"Yuzo","family":"Taenaka","sequence":"additional","affiliation":[{"name":"Information Technology Center, The University of Tokyo, Tokyo, Japan"}]},{"given":"Yuki","family":"Toyosaka","sequence":"additional","affiliation":[{"name":"Kyushu Institute of Technology, Iizuka-shi, Fukuoka, Japan"}]},{"given":"Ohnishi","family":"Yoshimasa","sequence":"additional","affiliation":[{"name":"Kyushu Institute of Technology, Iizuka-shi, Fukuoka, Japan"}]},{"given":"Kazunori","family":"Nishino","sequence":"additional","affiliation":[{"name":"Kyushu Institute of Technology, Iizuka-shi, Fukuoka, Japan"}]},{"given":"Yoshimi","family":"Fukumura","sequence":"additional","affiliation":[{"name":"Nagaoka University of Technology, Nagaoka-shi, Japan"}]}],"member":"2432","reference":[{"key":"ijtem.2014070103-0","unstructured":"Asou, K., Matsuba, R., Suzuki, K., & Nakano, H.
