    • Apparatus for identifying video content includes a scene detector to detect a plurality of consecutive scenes in the video content. The video content may include a video program and an advertisement contained within the video program. A signature generator determines a scene change signature for each of the plurality of consecutive scenes. A content identifier provides the plurality of scene change signatures to a comparator that compares the plurality of scene change signatures to a database having a plurality of video content items to identify the video program. The database includes an ordered plurality of previously determined scene change signatures for each item of video content in the database. The content identifier receives an identification of the video content from the comparator. The content identifier may further receive information related to a position of the plurality of scene change signatures within the ordered plurality of previously determined scene change signatures.
    • 用于识别视频内容的装置包括用于检测视频内容中的多个连续场景的场景检测器。 视频内容可以包括视频节目和包含在视频节目内的广告。 签名生成器确定多个连续场景中的每一个的场景变化签名。 内容标识符将多个场景改变签名提供给比较器,比较器将多个场景改变签名与具有多个视频内容项的数据库进行比较,以识别该视频节目。 数据库包括数据库中每个视频内容项目的有序多个先前确定的场景改变签名。 内容标识符从比较器接收视频内容的标识。 所述内容标识符还可以接收与所述有序多个先前确定的场景改变签名内的所述多个场景改变签名的位置有关的信息。
