| Abstract(in English) | Flipped classrooms have recently attracted many attentions as one of the model cases of active learning. In flipped classrooms, students tackle group discussions and exercises based on their active preparations using textbooks as well as online audio and video learning materials. It is, however, difficult for teachers to grasp each student's progress exactly. It is shown that image data hiding schemes based on complete complementary codes (CCC) are effective from the viewpoint of accurate extraction and payload capacity. In this study, we develop the online video learning materials using video data hiding based on CCC in order to facilitate the students' active learning and help teachers assess the students' works. In this paper, we propose a video data hiding scheme using CCC and evaluate the optimal parameters for embedding through numerical experiments. |
