    • A method comprises receiving user-generated auxiliary content and associated time data, the user-generated auxiliary content being associated with primary content from a primary media file, the time data indicating a least one portion of the primary content to which the user-generated auxiliary content relates; identifying, using the time data, at least a portion of the user-generated auxiliary content that relates to a portion of the primary content; storing, in a first storage file, the identified at least a portion of the user-generated auxiliary content; and storing, in association with the first storage file information identifying the portion of the primary content to which the at least a portion of the user-generated auxiliary content is related. A further method comprises receiving user-generated auxiliary content relating to at least one portion of the primary media content; and causing transmission of the received user-generated auxiliary content along with time data, the time data indicating at least one portion of the primary media content to which the user-generated auxiliary content relates.

    • A server system 500 is provided for receiving video clips having an associated audio/musical track for processing at the server system. The system comprises a beat tracking module for identifying beat time instants (t i ) in the audio signal and a chord change estimation module for determining a chord change likelihood from chroma accent information in the audio signal at the beat time instants (t i ). Further, first and second accent-based estimation modules are provided for determining respective first and second accent-based downbeat likelihood values from the audio signal at the beat time instants (t i ) using respective different algorithms. A final stage of processing identifies downbeats occurring at beat time instants (t i ) using a predefined score-based algorithm that takes as input numerical representations of chord change likelihood and the first and second accent-based downbeat likelihood values at the beat time instants (t i ).
    • 服务器系统500被提供用于接收具有相关音频/音轨的视频剪辑,用于在服务器系统处理。 该系统包括用于识别音频信号中的节拍时刻(ti)的拍子跟踪模块和用于在拍子时刻(ti))处从音频信号中的色度重音信息确定和弦变化似然度的和弦变化估计模块。 此外,第一和第二基于重音的估计模块被提供用于使用各自不同的算法从节拍时刻(ti)处的音频信号中确定相应的第一和第二基于重音的失真似然值。 处理的最后阶段使用预定义的基于分数的算法来识别在节拍时刻(ti)发生的乐观,该算法作为输入弦和弦变化可能性的数字表示以及在节拍时刻(ti)处的第一和第二基于重音的失真似然值 )。
