摘要： The invention relates to embedding a watermark into audio signals whilst taking account the binaural aspects of the human auditory system. The invention presents methods of embedding a watermark into a stereo or multichannel audio signal. These methods provide a robust watermarking to be used with various coding schemes of audio signals. The methods of the invention imply alteration of spatial image parameters of a stereo or multichannel system, viz. the inter-channel intensity difference (IID) and/or the inter- channel correlation (ICC), optionally supplemented by alterations of the inter-channel phase difference (IPD) and/or the inter-channel time difference (ITD).

摘要： An audio system comprises an encoder (209) which encodes audio objects in an encoding unit (403) that generates a down-mix audio signal and parametric data representing the plurality of audio objects. The down-mix audio signal and parametric data is transmitted to a decoder (215) which comprises a decoding unit (301) which generates approximate replicas of the audio objects and a rendering unit (303) which generates an output signal from the audio objects. The decoder (215) furthermore contains a processor (501) for generating encoding modification data which is sent to the encoder (209). The encoder (209) then modifies the encoding of the audio objects, and in particular modifies the parametric data, in response to the encoding modification data. The approach allows manipulation of the audio objects to be controlled by the decoder (215) but performed fully or partly by the encoder (209). Thus, the manipulation may be performed on the actual independent audio objects rather than on approximate replicas thereby providing improved performance.
摘要翻译：音频系统包括编码器（209），其在编码单元（403）中编码音频对象（403），该编码单元生成缩减混音音频信号和表示多个音频对象的参数数据。缩减混音音频信号和参数数据被发送到解码器（215），该解码器包括生成音频对象的近似副本的解码单元（301）和从音频对象生成输出信号的呈现单元（303）。解码器（215）还包含处理器（501），用于生成发送给编码器（209）的编码修改数据。编码器（209）然后响应于编码修改数据修改音频对象的编码，并且具体地修改参数数据。该方法允许操纵要由解码器（215）控制的音频对象，但完全或部分由编码器（209）执行。因此，可以对实际的独立音频对象而不是近似复制品执行操纵，从而提供改进的性能。

摘要： There is described a method of encoding input signals (CHI to CH3; 400 to 450) in a multi-channel encoder (5; 15) to generate corresponding output data comprising down-mix output signals (610, 620) together with complementary parametric data (600). The method includes a first step of down-mixing input signals (CHI to CH3; 400 to 450) to generate the corresponding down-mix output signals (610, 620), and a second step of processing the input signals (CHI to CH3; 400 to 450) during down-mixing to generate said parametric data (600) complementary to the down-mix output signals (610, 620). Processing of the input signals (CHI to CH3; 400 to 450) involves including information in the down-mix signals (610, 620) which is useable during subsequent decoding of the down-mix output signals (610, 620) and the parametric data (600) to determine at least some parameter data and thereby enabling representations of the input signals (CHI to CH3; 400 to 450) to be subsequently regenerated. Coders for use in the encoder (5; 15) for performing essential signal processing operations therein are also elucidated.
