This paper proposes a video switching method for meeting scenes based on time shifting. First, the audio/video streams are captured by multiple video cameras. Those streams are not directed and transmitted in real time, but are buffered on a memory for Δt seconds. During the buffering, the conversational history of the scene is collected by various sensors simultaneously. Finally, the buffered streams are directed and merged into one stream based on the history. Even though there remains some delay, the stream can be well directed than that directed in real time. A prototype system was implemented and evaluated by experiments. The experimental results indicated that the prototype system could direct the meeting scene to be smooth as well as actual TV-drama program.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"923","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"915","bibliographicIssueDates":{"bibliographicIssueDate":"2006-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"47"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"グループウェア"}]},"weko_creator_id":"1"},"id":10377,"links":{}}
