    • An audio processing device including a feature calculation unit, a boundary calculation unit and a judgment unit, detects points of change of audio features from an audio signal in an AV content. The feature calculation unit calculates, for each unit section of the audio signal, section feature data expressing features of the audio signal in the unit section. The boundary calculation unit calculates, for each target unit section among the unit sections of the audio signal, a piece of boundary information relating to at least one boundary of a similarity section. The similarity section consists of consecutive unit sections, inclusive of the target unit section, which each have similar section feature data. The judgment unit calculates a priority of each boundary indicated by one or more of the pieces of boundary information and judges whether the boundary is a scene change point based on the priority.
    • 包括特征计算单元,边界计算单元和判断单元的音频处理设备从AV内容中的音频信号中检测音频特征的变化点。 特征计算单元针对音频信号的每个单位部分计算表示单位部分中的音频信号的特征的部分特征数据。 边界计算单元对于音频信号的单位部分中的每个目标单位部分计算与相似度部分的至少一个边界相关的边界信息。 相似部分由连续的单位部分组成,包括目标单位部分,每个部分具有类似的部分特征数据。 判断单元计算由一个或多个边界信息指示的每个边界的优先级,并且基于优先级来判断边界是否是场景改变点。
