to the COVID-19 pandemic, many universities have conducted lectures online. Although online lectures reveal various advantages, face-to-face classes are also demanded. Thus, at the University of Tokyo, we plan to start “hybrid” lectures in which both online and face-to-face classes are given to live with COVID-19. However, it is not clear how much network bandwidth is required to make such a type of lecture possible. In this study, we set up a classroom to evaluate whether or not a large number of students can attend an online lecture in a classroom. Furthermore, we observed the network condition and the quality of the audio and video of the online lecture. In this paper, we present the results of the experiments and the findings.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"76","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌デジタルプラクティス（TDP）"}],"bibliographicPageStart":"66","bibliographicIssueDates":{"bibliographicIssueDate":"2022-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":219018,"updated":"2025-01-19T14:57:14.393562+00:00","links":{},"created":"2025-01-19T01:19:21.402248+00:00"}
