this paper we propose ``contents oriented time and Spatial resolution control  Scheme for Mobile multimedia streaming service (SSM)'' which provides high quality multimedia data transmission even on unstable wireless links with control of time and spatial resolution of multimedia data.Instead of simply thinning down the time resolution of multimedia data or degrading the spatial resolution according to the status of wireless links,SSM uses semantic priorities assigned to each movie frame or audio sample to control the time and spatial resolution of the multimedia data to be sent.When effective bandwidth degrades,SSM degrades spatial resolution of movie frames or audio samples assigned low priority.And it sends them with other data assigned high priority without degrading the resolution.By controlling not only time resolution but spatial resolution,multimedia data can be played comfortably on the receiver side.We implemented SSM,and confirmed the effectiveness by subjective evaluations of quality of multimedia data transmitted by SSM.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3847","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3838","bibliographicIssueDates":{"bibliographicIssueDate":"2002-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"43"}]},"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":"QoS制御"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:46:02.281636+00:00","id":11396,"links":{}}
