The protocol technically and economically makes it easy for those who desire to stream their audio-visual materials or lectures, such as college lectures to install and administer it in their computer network environment. However, becuase the HLS protocol is provided by Apple Inc., uncertainty exists as to whether movies can be reproduced correctly onWindows PCs and Android tablets (i.e., non-Apple devices) when they are streamed using the HLS protocol. The fact is that a number of people are currently using such devices. Consequently,in this paper, we spropose a method by which HLS movies can be accurately reproduced on non-Apple devices without requiring special settings. Further, we discuss the implementation of a prototype system using Moodle and the problems countered in the process.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"天使大学","subitem_publisher_language":"ja"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-4388","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"川口, 雄一","creatorNameLang":"ja"},{"creatorName":"カワグチ, ユウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"KAWAGUCHI, Yuuichi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"目時, 光紀","creatorNameLang":"ja"},{"creatorName":"メトキ, ミツタダ","creatorNameLang":"ja-Kana"},{"creatorName":"METOKI, Mitsutada","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-07-23"}],"displaytype":"detail","filename":"kiyou14(2)_11.pdf","filesize":[{"value":"4.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kiyou14(2)_11","url":"https://tenshi.repo.nii.ac.jp/record/260/files/kiyou14(2)_11.pdf"},"version_id":"f957a212-121c-4367-ab1a-c5a205a933d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"HLS ストリーミング","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"非アップル端末","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ムードル","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"認証","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"HTTP Live Streaming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"non-Apple Devices","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Moodle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Authentication","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"非アップル端末によるHLS ストリーミング動画の再生","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非アップル端末によるHLS ストリーミング動画の再生","subitem_title_language":"ja"},{"subitem_title":"Playback of Movies with HLS Streaming on non-Apple Devices","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"15","path":["29"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-07-23"},"publish_date":"2014-07-23","publish_status":"0","recid":"260","relation_version_is_last":true,"title":["非アップル端末によるHLS ストリーミング動画の再生"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-06-21T07:17:01.097668+00:00"}
