DASH - AWS Elemental MediaTailor

本文為英文版的機器翻譯版本,如內容有任何歧義或不一致之處,概以英文版為準。

DASH

MediaTailor 使用廣告決策伺服器 (ADS) 傳回的廣告素材來個人化資訊清單。對於每個廣告, MediaTailor 還包括跨越廣告持續時間的EventStream元素。Event元素格式與 2023 版 S VA 技術出版物中的 DASH 和 HLS 廣告創意信號一節中所述的格式相似。

針對已啟用平板的設定上填滿不足的廣告插播,會將平板期間 MediaTailor 附加至可用期結束,但不含任何中繼資料 EventStream

針對連結到個人化資訊清單中的每個廣告,都會 MediaTailor 新增廣告素材中繼資料 (以CDATA元素中的元Event素表示)。
