    • The invention relates to an apparatus for selecting at least one program item to be stored on the basis of user preferences. The apparatus comprises a receiver (110) for obtaining program schedule data related to at least one program item, and a timer (150) arranged to ascertain a period of time in which at least one program item is to be stored, a user preference module (130) arranged to obtain user preferences for at least one program item to be stored in the ascertained period of time, and a selection unit (140) arranged to select, using the program schedule data and the user preferences, at least one program item to be stored over a long period of time which is substantially longer than regular periods of non­usage of the apparatus. The invention takes into consideration that the user preferences for storing the program items may depend on the period of time in which the program items are to be selected.
    • 本发明涉及一种用于基于用户偏好来选择要存储的至少一个程序项目的装置。 该装置包括:用于获得与至少一个节目项目有关的节目安排数据的接收机(110);以及定时器(150),其被布置为确定要存储至少一个节目项目的时间段;用户偏好模块 (130),其被布置为获得要在所确定的时间段内存储的至少一个节目项目的用户偏好;以及选择单元(140),其被布置为使用所述节目安排数据和所述用户偏好来选择至少一个节目项目 要长时间地存储,其长度大大超过设备的不正常周期。 本发明考虑到存储程序项目的用户偏好可以取决于要选择程序项目的时间段。

    • The invention relates to a method of processing data, the method comprising steps of enabling to (210) encrypt first data for a first source, and encrypt second data for a second source, (220) provide the encrypted first and second data to a server that is precluded from decrypting the encrypted first and second data, and from revealing identities of the first and second sources to each other, (230) perform a computation on the encrypted first and second data to obtain a similarity value between the first and second data so that the first and second data is anonymous to the second and first sources respectively, the similarity value. providing an indication of a similarity between the first and second data. The method may further comprise a step (240) of using the similarity value to obtain a recommendation of a content item for the first or second source. The first or second data may comprises a user profile or user ratings of content items. One of the applications of the method may be in collaborative filtering systems.
    • 本发明涉及一种处理数据的方法,所述方法包括以下步骤:(210)为第一源加密第一数据,并为第二源加密第二数据,(220)将加密的第一和第二数据提供给服务器 (230)对加密的第一和第二数据执行计算以获得第一和第二数据之间的相似性值 使得第一和第二数据分别对第二和第一源匿名,即相似度值。 提供第一和第二数据之间的相似性的指示。 该方法可以进一步包括使用相似度值来获得第一或第二来源的内容项目的推荐的步骤(240)。 第一或第二数据可以包括用户简档或内容项目的用户评级。 该方法的应用之一可以在协同过滤系统中。
