A dis tinctive feature of the system is the separation of the reproduction system and the display system for lyrics. The watermarking technique is robust against reflections and reverberations, because the technique applies relatively slow amplitude modulation in a long embedding frame of several seconds. The technique can cancel additive noise in the detection stage. The robustness of the system was evaluated by a computer simulation in terms of the correct rate of data transmission under reverberant and noisy conditions reproduced by a loudspeaker. The results showed that the performance of detection and the temporal precision of synchronization of display were sufficient.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"12","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学(MUS)"}],"bibliographicPageStart":"7","bibliographicIssueDates":{"bibliographicIssueDate":"2007-08-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"81(2007-MUS-071)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":55761,"links":{}}
