In here, we hide or reduce a load on decompression of the storage data by using \"speculative execution\" technique in parallel environments. Although a video database is effective for a base of a video editing system, it is not easy to store enough number of video data that will be worth called \"database\". An evaluation in this paper shows that we may expect to obtain from 3.4 to 9.5% gain for a video database capacity which makes it possible to store more number of video data than conventional video databases.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110002930649","subitem_relation_type_select":"NAID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意：本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 "},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
