    • Disclosed is a method for identifying content within a received information signal. The method comprises receiving (S6) an information signal; generating (S8) a first data set by selecting a sub-set of data (7) using filter data; and processing (S9) said information signal with reference to said first data set to determine whether said information signal comprises particular content. Advantageously, the method further comprises processing (S 12) the information signal with reference to a second data set (6) to determine whether said information signal comprises particular content. The invention allows content sharing sites such as YouTube to check whether uploaded files violate copyright rules in case the upload includes contents that was previously downloaded by the client. By keeping a list of contents that clients have downloaded, the server has an indication of a subset of contents that will likely be included in the next upload by the same client. As this subset is relatively small, a finer fingerprint resolution may be applied to this subset.
    • 公开了一种用于识别接收的信息信号内的内容的方法。 该方法包括:接收(S6)信息信号; 通过使用过滤数据选择数据(7)的子集来生成(S8)第一数据集; 以及参考所述第一数据集处理(S9)所述信息信号,以确定所述信息信号是否包含特定内容。 有利地,该方法还包括参考第二数据集(6)处理(S12)信息信号,以确定所述信息信号是否包含特定内容。 本发明允许诸如YouTube之类的内容共享站点检查上传的文件是否违反版权规则,以防上载包含客户端先前下载的内容。 通过保留客户端下载的内容列表,服务器具有可能被同一客户端下次上传的内容的子集的指示。 由于该子集相对较小,因此可以将更精细的指纹分辨率应用于该子集。

    • 公开了一种用于识别接收到的信息信号内的内容的方法。 该方法包括接收(S6)信息信号; 通过使用滤波器数据选择数据(7)的子集来生成(S8)第一数据集; 以及参照所述第一数据集处理(S9)所述信息信号以确定所述信息信号是否包括特定内容。 有利地,该方法还包括参照第二数据集(6)处理(S12)该信息信号以确定所述信息信号是否包括特定内容。 本发明允许诸如YouTube的内容共享站点检查上传的文件是否违反版权规则,以防上传包括先前由客户端下载的内容。 通过保留客户端下载的内容列表,服务器会指示可能包含在同一客户端的下一次上传中的内容子集。 由于该子集相对较小,因此可以将更精细的指纹分辨率应用于该子集。
