Nevertheless, in many cases a receiver can not arrange video windows of received streams freely because of a static layout design. To address this problem, we propose a streaming system which is sophisticated from the viewpoint of a receiver. It enables following functions: a receiver-driven flexible layout function of video windows, a screen sharing function which is mutually synchronized among receivers, and a public viewing function with interactive communication between receivers. In this paper, we describe the system design and its implementation, and we show the effectiveness of the proposed functions through the subjective assessment.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"34","bibliographicVolumeNumber":"2010-IOT-8"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"updated":"2025-01-22T00:27:33.467286+00:00","created":"2025-01-18T23:28:05.421684+00:00","id":67870}
