    • The present invention relates generally to audio and video processing, e.g., with digital watermarking. One claim recites an apparatus including: electronic memory for buffering data representing audio or video, and an electronic processor. The electronic processor is programmed for: (i) controlling receipt of data representing audio or video, the data representing audio or video comprising at least two digital watermark layers, the first watermark layer comprising a content identifier which uniquely identifies the content, and the second watermark layer comprising a distributor identifier which identifies a distributor or distribution channel associated with the content; and (ii) embedding a third watermark layer in the audio or video, in which the third watermark layer is embedded through alterations to data representing audible portions of the audio or through alterations to data representing video picture elements of the video, and in which each of the first watermark layer, the second watermark layer and the third digital watermark layer are embedded in the audio or video content with different watermark protocols or different watermark keys. Of course, other claims are provided as well.
    • 本发明一般涉及音频和视频处理,例如利用数字水印。 一个权利要求描述了一种装置,包括:用于缓冲表示音频或视频的数据的电子存储器和电子处理器。 电子处理器被编程为:(i)控制表示音频或视频的数据的接收,表示包括至少两个数字水印层的音频或视频的数据,所述第一水印层包括唯一地标识内容的内容标识符,以及第二 水印层包括识别与内容相关联的分发者或分发信道的分发者标识符; 和(ii)在音频或视频中嵌入第三水印层,其中通过对表示音频的可听部分的数据的改变来嵌入第三水印层,或者通过对表示视频的视频图像元素的数据的改变来嵌入第三水印层,并且其中每个 的第一水印层,第二水印层和第三数字水印层嵌入在具有不同水印协议或不同水印键的音频或视频内容中。 当然,也提供其他权利要求。
