However, there is the problem that sound quality degradation is likely to be perceived according to multi-layered embedding process. In this research, we reduce the sound quality degradation by introducing \"optimized window function\" and \" sound quality improvement technique using error correcting code\" into the multilayer type audio watermarking method. As a consequence, we realized the balance of embedding capacity and sound quality.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究（C）;  研究期間：2011～2013;   課題番号：23500224;   研究分野：総合領域   科研費の分科・細目：情報学、知覚情報処理・知能ロボティクス","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://kaken.nii.ac.jp/d/r/60244654.ja.html"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://kaken.nii.ac.jp/d/r/10707186.ja.html"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"OGIHARA, Akio"},{"subitem_text_language":"en","subitem_text_value":"MURATA，Harumi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工学部; 教授"},{"subitem_text_value":"中京大学工学部; 助教"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"荻原, 　昭夫"},{"creatorName":"オギハラ, アキオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"村田,  晴美"},{"creatorName":"ムラタ, ハルミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-31"}],"displaytype":"detail","filename":"KAKEN_23500224seika.pdf","filesize":[{"value":"97.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_23500224seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/13944/files/KAKEN_23500224seika.pdf"},"version_id":"911fc142-7fcf-4c5d-bffc-d5838cd08054"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"音楽電子透かし","subitem_subject_scheme":"Other"},{"subitem_subject":"情報ハイディング","subitem_subject_scheme":"Other"},{"subitem_subject":"著作権・コンテンツ保護","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"埋込容量の増大が可能な多層型音楽電子透かしの音質改善手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"埋込容量の増大が可能な多層型音楽電子透かしの音質改善手法"}]},"item_type_id":"8","owner":"3","path":["2672"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-12"},"publish_date":"2014-10-12","publish_status":"0","recid":"13944","relation_version_is_last":true,"title":["埋込容量の増大が可能な多層型音楽電子透かしの音質改善手法"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T23:07:01.091832+00:00"}
