Unlike previous works, which mainly discuss MVV transmission from aspects of video codecs, we study MVV and audio transmission under various IP traffic and delay conditions by experiment. We compare two schemes: a scheme that the user watches from a single viewpoint and the one that he/she can choose one viewpoint from many ones. As a result, we show that the users prefer the scheme where they can choose one viewpoint from many ones. We have found that when using proper buffering time, the users feel faster viewpoint changes; it improves their satisfaction compared to that when they watch on a single viewpoint. We have also noticed that the user pays more attention to the degradation of the video when watching on a single viewpoint. We have observed that the users tend to change the viewpoint more frequently in light traffic and low delay.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"布目, 敏郎"}]},{"nameIdentifiers":[{}],"names":[{"name":"田坂, 修二"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers"}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168516","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"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":[{"creatorNames":[{"creatorName":"Jimenez, Rodriguez  Erick","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nunome, Toshiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Tasaka, Shuji","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":"2017-01-26"}],"displaytype":"detail","filename":"E93-B_1373.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","license_note":"Copyright (c) 2010 IEICE　http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5505/files/E93-B_1373.pdf"},"version_id":"763dfccd-e8be-4d4d-9af4-4e0058351938"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"QoE Assessment of Multi-View Video and Audio IP Transmission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"QoE Assessment of Multi-View Video and Audio IP Transmission","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-25"},"publish_date":"2013-06-25","publish_status":"0","recid":"5505","relation_version_is_last":true,"title":["QoE Assessment of Multi-View Video and Audio IP Transmission"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T14:22:08.055542+00:00"}
