    • The invention relates to a method of informing a user about a category (152) of a media content item. The method comprises the steps of: identifying the category of the media content item, and enabling a user to obtain an audible signal (156) having an audio parameter (153) in accordance with the category of the media content item. The invention further relates to a device, which is capable of functioning in accordance with the method. The invention also relates to audio data comprising an audible signal informing a user about a category of a media content item, a database comprising a plurality of the audio data, and a computer program product. In a recommender system, the audible signal may be reproduced by the recommender system when a user interaction with the recommender system relates to the media content item of a particular genre. The invention may be used in the EPG user interface.
    • 本发明涉及一种通知用户关于媒体内容项目的类别(152)的方法。 该方法包括以下步骤:识别媒体内容项的类别,以及使用户能够根据媒体内容项的类别获得具有音频参数(153)的可听信号(156)。 本发明还涉及一种能够根据该方法起作用的装置。 本发明还涉及音频数据,其包括通知用户关于媒体内容项目的类别的可听信号,包括多个音频数据的数据库以及计算机程序产品。 在推荐系统中,当与推荐系统的用户交互涉及特定类型的媒体内容项时,可以由推荐系统再现可听信号。 本发明可以用在EPG用户界面中。

    • The present invention relates to a device and a method for authorizing a user to get access to content stored in encrypted form on a storage medium (10), said storage medium storing a machine-readable medium identifier (id) and at least one key table (KL) encrypted by use of a key table key (KLK) and storing at least one asset key (AK) for decrypting encrypted content (C). In order to allow a user to provide access to the content to other users in a simple but secure way, a device is proposed comprising: - a connection means (6) for connecting said device to a network (3), - a drive (5) for accessing said storage medium (10), in particular for reading content (C) and said medium identifier (id) from said storage medium (l0), and - a transmitter (7) for transmitting said medium identifier (id) and a user identifier (ui) of a user, who shall be authorized to get access to said content (C) and who is identified to said network (3) by said user indentifier (ui), to an authentication unit (AuC) within said network (3), said medium identifier (id) and said user identifier (ui) being used by said authentication unit (AuC) for generating a key table key (KLK) for said user enabling said user to decrypt at least one predetermined key table (KL).
    • 本发明涉及一种用于授权用户访问以加密形式存储在存储介质(10)上的内容的设备和方法,所述存储介质存储机器可读介质标识符(id)和至少一个密钥表 (KLK)通过密钥表密钥(KLK)加密并存储用于解密加密内容(C)的至少一个资产密钥(AK)。 为了允许用户以简单但安全的方式向其他用户提供对内容的访问,提出了一种设备,其包括: - 用于将所述设备连接到网络(3)的连接装置(6), - 驱动器 5)用于访问所述存储介质(10),特别是用于从所述存储介质(10)读取内容(C)和所述介质标识符(id);以及 - 发送器(7),用于发送所述介质标识符(id)和 用户的用户标识符(ui),被授权通过所述用户标识符(ui)访问所述内容(C)以及被识别到所述网络(3)的用户标识符(ui)到所述用户标识符(ui)内的认证单元(AuC) 网络(3),所述介质标识符(id)和所述用户标识符(ui)被所述认证单元(AuC)用于生成用于所述用户的密钥表密钥(KLK),使得所述用户能够解密至少一个预定密钥表 (KL)。
