The latest international video coding standard, Versatile Video Coding (VVC) published in 2020, achieves approximately twice as high compression ratio as the conventional HEVC (High Efficiency Video Coding), while significantly increasing the encoding processing time. This paper proposes a block partitioning decision method based on video features for VVC to reduce the encoding time. The evaluation results show that, compared to the reference software for VVC, the proposed method can reduce the encoding time by 59.45% for 2K and 66.44% for 4K on average while suppressing BDBR degradation.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-08-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"29","bibliographicVolumeNumber":"2024-ARC-258"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":237623,"updated":"2025-01-19T08:49:20.554045+00:00","links":{},"created":"2025-01-19T01:40:21.416331+00:00"}
