demand for low-latency transmission of high-definition video in various systems such as autonomous driving, VR, and UAV has been increasing, so efficient low-latency video coding schemes are required. We have previously reported the ultra-low-latency video coding method for Full-HD that achieves ultra-low latency on the order of μs by line-based processing. In this paper, we introduce three new ultra-low latency video coding schemes for higher resolution 4K/8K. First, we propose optimization by extending the coding processing unit. Second, we propose inter-frame prediction using RFMS (Reduced Frame Memory Structure) to predict from pixels in the same position of the previous frame. Third, we propose the original line-based CAVLC referring to H.264's CAVLC. We have confirmed that the proposed method can significantly improve the bit rate of 4K/8K video with the same image quality.","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":"2023-12-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2023-AVM-123"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":231478,"updated":"2025-01-19T10:44:52.970025+00:00","links":{},"created":"2025-01-19T01:31:48.401545+00:00"}
