Abstract: A video services receiver and related operating methods are disclosed here. In accordance with one disclosed methodology, the video services receiver receives a segment of video content, and processes a plurality of contiguous sub-segments of the segment of video content to generate a corresponding plurality of characterizing signatures. Each of the characterizing signatures identifies a respective one of the contiguous sub-segments. The video services receiver compares the characterizing signatures to video content signatures maintained in a database. When the results of the comparing satisfy predetermined matching criteria, the video services receiver initiates an operation that influences presentation attributes of the segment of video content.

Abstract translation: 这里公开了视频服务接收器和相关的操作方法。 根据一个公开的方法，视频服务接收器接收视频内容的一部分，并且处理视频内容片段的多个连续的子片段以生成相应的多个表征签名。 每个特征签名标识相邻的一个连续的子段。 视频服务接收器将特征签名与维护在数据库中的视频内容签名进行比较。 当比较结果满足预定的匹配标准时，视频服务接收器启动影响视频内容片段的呈现属性的操作。
