摘要： Methods and apparatus provide for a Content Inserter to determine location(s) for secondary content in streaming video. The Content Inserter receives a set of video frames and analyzes data differential(s) occurring in the set of video frames to identify secondary content locations between adjacent video frames. The Content Inserter inserts secondary content at the location(s) for secondary content. A data differential can be a change in subtitle information between video frames, a change in audio data between video frames, a difference in content ratings between regions of video frames, and/or difference in activity levels between regions of video frames. Activity levels correspond to changes in pixel color data of video frames. Thus, the Content Inserter identifies secondary content locations based on characteristics of each video stream and ensures that inserted secondary content is placed in a video stream so that the secondary content will most likely be viewed.
摘要翻译：方法和装置提供内容插入器来确定流视频中次要内容的位置。内容插播器接收一组视频帧并且分析在该组视频帧中发生的数据差异以识别相邻视频帧之间的次要内容位置。内容插入程序在次要内容的位置插入辅助内容。数据差分可以是视频帧之间的字幕信息的改变，视频帧之间的音频数据的改变，视频帧的区域之间的内容等级的差异和/或视频帧的区域之间的活动水平的差异。活动级别对应于视频帧的像素颜色数据的变化。因此，内容插入器基于每个视频流的特征来识别辅助内容位置，并确保将插入的次要内容放置在视频流中，使得次要内容最有可能被查看。
