Coding of UHDTV needs enormous operations to meet a high accuracy requirement for motion estimation. Due to enormous operations, parallel processing is indispensible for real time encoding. But, the transmission bottleneck of a reference frame becomes an obstacle forhighly parallel processing. In this paper, I proposed a new distributed reference memory architecture that dissolved the transmission bottleneck at hierarchical motion estimation, which used square pattern search in 2nd search and 3rd search. At proposed memory architecture, it is possible to transmit pixel data by line units. Through this architecture, it suppresses an increase memory area, and can parallel processing. Also, an improvement adding a buffer between a block matching array and its local memory units is effective to reduce memory unit access rate or memory unit power consumption","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"三重大学大学院工学研究科博士前期課程情報工学専攻","subitem_description_type":"Other"},{"subitem_description":"4, 32","subitem_description_type":"Other"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Master's Thesis / 修士論文"}]},"item_7_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"友永, 大貴","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"22936","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"2011M256.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2011M256.pdf","url":"https://mie-u.repo.nii.ac.jp/record/9195/files/2011M256.pdf"},"version_id":"99eb1d5d-0a9a-47a7-8d74-f4b9af10d999"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"超高精細動画像動き検出用参照画像メモリ構成法の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超高精細動画像動き検出用参照画像メモリ構成法の研究","subitem_title_language":"ja"}]},"item_type_id":"7","owner":"15","path":["648"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-06-11"},"publish_date":"2013-06-11","publish_status":"0","recid":"9195","relation_version_is_last":true,"title":["超高精細動画像動き検出用参照画像メモリ構成法の研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-09-11T01:56:47.041422+00:00"}
