However, there is the problem that sound quality degradation is likely to be perceived according to multi-layered embedding process. In this research, we control the number of layers in multilayer type audio watermarking method according to the sound quality obtained by objective sound quality evaluation method with biological signal. 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：2014～2016;   課題番号：26330214;   研究分野：音響情報処理;   科研費の分科・細目：","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":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26330214/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"OGIHARA, Akio"}]},"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"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"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":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-01"}],"displaytype":"detail","filename":"26330214seika.pdf","filesize":[{"value":"220.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"26330214seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18894/files/26330214seika.pdf"},"version_id":"95619eed-ae2b-43f8-a19a-5c64a6fe7a99"}]},"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"}]},"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":"多層型音楽電子透かしにおける階層数による音質制御法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多層型音楽電子透かしにおける階層数による音質制御法"},{"subitem_title":"A sound quality control method based on the number of layers in multilayer type audio watermarking","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4374"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-01"},"publish_date":"2017-11-01","publish_status":"0","recid":"18894","relation_version_is_last":true,"title":["多層型音楽電子透かしにおける階層数による音質制御法"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:51:14.369843+00:00"}
