Since content transmission to AR viewer devices is mainly through wireless communication (Wi-Fi, 4G/5G), stable reception of high-bitrate 3D content poses many challenges. In this paper, we propose a visible object filter function implemented in the gateway on the network. In order to improves the efficiency of bandwidth utilization in the wireless transmission and to enable more stable reception in the transmission of 3D content, the visible object filter only passes the data of objects in the field of view of AR among multiple 3D objects such as performers and static objects.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-11-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2021-AVM-115"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":213827,"updated":"2025-01-19T17:00:26.686334+00:00","links":{},"created":"2025-01-19T01:14:40.314448+00:00"}
