However, the real-time broadcasting requires specialized literacy and an environment. In this research, we implement a platform for real-time broadcasting that is easy to use even for beginners, using BaaS (Broadcast as a Service) and cloud computing as a support environment for real-time broadcast. The prototype is designed with UI for mobile devices, and experiments are conducted under 4G and 5G communications using WebRTC for video streaming.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-09-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2021-DPS-188"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":212766,"updated":"2025-01-19T17:23:08.682491+00:00","links":{},"created":"2025-01-19T01:13:41.914892+00:00"}
