    • This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronisation of at least two signals (101,103) and corresponding method and device for synchronising two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronisation time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronisation device (303). During synchronisation, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronised are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronisation time point, which is used to synchronise the two signals. In this way, a simple, reliable and efficient way of synchronising at least two signals is obtained. Further, this is enabled without modifying either the first and second signal (or subsequent signals). The signals may even be distorted or changed to some extent while still enabling synchronisation.
    • 本发明涉及一种生成可用于同步至少两个信号(101,103)的第一和第二指纹(102,104)的设备和方法以及用于同步两个或多个信号的相应方法和设备。 基于第一信号的片段例如生成指纹对。 音频信号和第二信号的片段。 在每个同步时间点的视频信号。 所生成的指纹对存储在数据库(203)中并被传送或分发给同步装置(303)。 在同步期间,生成要同步的视频信号的音频信号的指纹和指纹,并与数据库中的指纹进行匹配。 当发现匹配时,指纹也决定同步时间点,用于同步两个信号。 以这种方式,获得了同步至少两个信号的简单,可靠和有效的方式。 此外,这可以在不修改第一和第二信号(或后续信号)的情况下实现。 信号甚至可能在一定程度上失真或改变,同时仍然允许同步。

    • A universal memory device is presented that provides adaptability to existing hardware and software environments. The memory can “mimic” existing memory technology combining the advantages of integrating all memory capacity into one single technology and still providing the implicit protections and access characteristics known from the different existing memory technologies. The memory device comprises a memory having low-latency, rewritable, non-volatile memory cells, a profile storage unit connected with the memory and comprising access information allocated to a set of request information elements (request profile), such that the access information indicates whether an access request to said memory, the access request having the request profile, is to be allowed or rejected, and an access control unit communicating with the profile storage unit and the memory, and adapted to allow or reject an incoming access request in dependence on the access information allocated to the request profile of the access request.
