progress has been made in technologies that enable us to view 360-degree omnidirectional Virtual Reality (VR) content and to become avatars in the virtual world so that we could enjoy communication with other avatars. Immersive media is an advanced form of applications such as VR and eXtended Reality (XR). It allows users to move freely in a video space that makes use of the real world and virtual world without distinction, and to view images from any location. It is a 6 degrees of freedom (DoF) media that provides users with experiences that feel as though they are in the video space. We are promoting research and development to realize immersive media that can be used on various types of devices. In this work, we propose a system that renders the immersive content consisting of scene descriptions, volumetric video, 360-degree video, and 2D video, over a network in order to produce images for presenting on devices having different capabilities. This report presents our experimental findings on the motion-to-photon latency, which is defined as the time it takes between the user moving their position/direction and this motion being reflected on the screen of device, in the case of a renderer built on a virtual server on Amazon Web Service (AWS), one of the widely used cloud. It also presents our findings on the number of devices that can be connected to one rendering server on the cloud.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告高度交通システムとスマートコミュニティ（ITS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-05-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"28","bibliographicVolumeNumber":"2024-ITS-97"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:35:42.552118+00:00","updated":"2025-01-19T09:54:37.292203+00:00","id":234003}
