摘要： The present invention relates to a method for a service provider to distribute an audio signal to a listener. Before delivering the audio signal to the listener, the audio impression of the audio signal is personalized to the listener. The personalizing could e.g. be performed by filtering the audio signal using a set of head related transfer functions (HRTFs) defined by parameters being specific for the listener. This is for minimizing the interest of performing illegal copying of the audio signal. The invention further relates to a method of playing back a distributed audio signal and a playback device for playing back a distributed audio signal, where the personalization is detected and used as a watermark, which is identified and interpreted before playing back the distributed audio.

摘要： A method of regulating sharing of a multimedia object (200) by a device (100), comprising registering usage information for the multimedia object (200) upon sharing of the multimedia object (200), and after the registering, billing a user of the device (100) for a certain amount in accordance with the registered usage information for the multimedia object (200). Registration preferably takes place in a client (101) arranged for sharing of the multimedia object (200). The usage information could for instance comprise the number of times a multimedia object has been shared, or the duration of the object. If a sufficient number of objects have been shared, or if the total time exceeds a maximum, the client (101) reports the usage information to a third party (130) for billing purposes.
摘要翻译：一种调节由设备（100）共享多媒体对象（200）的方法，包括在多媒体对象（200）共享时登记多媒体对象（200）的使用信息，并且在注册之后，对设备（100）根据多媒体对象（200）的注册使用信息确定一定量。注册优选地在被布置为共享多媒体对象（200）的客户端（101）中进行。使用信息可以例如包括多媒体对象已被共享的次数或对象的持续时间。如果已经共享了足够数量的对象，或者如果总时间超过最大值，则为了计费的目的，客户端（101）将使用信息报告给第三方（130）。
