We focus on the congestion control, this phenomenan appears as decrease of the data-processing speed in trasncoder. By using this influence, the rate control completed only by transcoder without using other protocols. First, we clarify the relation of the data-processing speed in transcoder, the conversion rate of transcoder, and a transmission rate. Next, we propose dynamic rate control method which carries out feedback control to a presumed transmission rate, and show the effectiveness of the proposal scheme.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"28","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"23","bibliographicIssueDates":{"bibliographicIssueDate":"2004-06-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"65(2004-AVM-045)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
