    • Trick mode play for controlling video content playback can be realized using a semantic based criterion in order to achieve a more uniform playback experience for the viewer, when that viewer wishes to observe the video content presented according to a selected semantic. In one embodiment of the method, semantics associated with shorter time intervals in the video content are replayed in trick mode play proportionally slower than semantics associated with longer time intervals, wherein the proportionally is determined, at least in part, to the time interval associated with each semantic. In various embodiments, semantics can include scenes, audio, metadata, tags, and the like. The semantics based trick mode play approach allows for a more uniform viewing experience, on a time duration basis, from one semantic to the next.
    • 可以使用基于语义的标准来实现用于控制视频内容回放的模式播放,以便当观众希望观察根据所选语义呈现的视频内容时,为观众提供更均匀的播放体验。 在该方法的一个实施例中,与特征模式播放相关联的与视频内容中较短时间间隔相关联的语义比与较长时间间隔相关联的语义成比例地慢,其中,至少部分地至少部分地确定与 每个语义。 在各种实施例中,语义可以包括场景,音频,元数据,标签等。 基于语义的特技模式播放方法允许在时间基础上从一个语义到另一个语义的更均匀的观看体验。
