    • An audio data segmentation apparatus for segmenting of audio data comprises audio data input means for supplying audio data, audio data clipping means for dividing the audio data supplied by the audio data input means into audio clips of a predetermined length, class discrimination means for discriminating the audio clips supplied by the audio data clipping means into predetermined audio classes, the audio classes identifying a kind of audio data included in the respective audio clip and segmenting means for segmenting the audio data into audio meta patterns based on a sequence of audio classes of consecutive audio clips, each meta pattern being allocated to a predetermined type of contents of the audio data. It is difficult to achieve good results with known methods for segmentation of audio data into meta patterns since the rules for the allocation of the meta patterns are dissatisfying. This problem is solved by the inventive audio data segmentation apparatus further comprising a programme database comprising programme data units to identify a certain kind of programme, a plurality of respective audio meta patterns being allocated to each programme data unit, wherein the segmenting means segments the audio data into corresponding audio meta patterns on the basis of the programme data units of the programme database 5.
    • 用于分割音频数据的音频数据分割装置包括用于提供音频数据的音频数据输入装置,用于将由音频数据输入装置提供的音频数据分割成预定长度的音频剪辑的音频数据剪辑装置,用于鉴别 由音频数据剪辑装置提供的音频剪辑成预定的音频类别,音频类别标识包括在各个音频剪辑中的一种音频数据,以及分割装置,用于基于连续的音频类别序列将音频数据分割成音频元模式 音频剪辑,每个元模式被分配给音频数据的预定类型的内容。 由于元模式的分配规则不满意,因此将音频数据分割为元模式的已知方法难以获得良好的结果。 本发明的音频数据分割装置还包括程序数据库,该程序数据库包括用于识别某种程序的程序数据单元,分配给每个程序数据单元的多个各自的音频元模式,其中分段装置分割音频 基于程序数据库5的程序数据单元将数据转换成相应的音频元模式。
