    • A content distribution system (300) has access control according to a predefined data access format. The system has organizations (32) for providing content data and related meta data on record carriers (34), and a rendering device (39), and applications for manipulating the content data and related meta data. An access policy for the organization is set according to the predefined data access format, and has access parameters for controlling access to resources of the rendering device and to said content data and related meta data. An organization application (35) complying with the access policy of the organization for accessing said data is executed while accessing the resources of the rendering device according to the access policy of the organization. According to the invention a user access policy is maintained that restricts, for the organization application, access to the resources of the rendering device relative to the access policy of the organization. The user access policy is adjusted based on additional trust data for selectively allowing the organization application to access the resources according to the access policy of the organization. Hence the user controls the access that applications have to resources of the rendering device.
    • 内容分发系统(300)具有根据预定义的数据访问格式的访问控制。 该系统具有用于在记录载体(34)上提供内容数据和相关元数据的组织(32),以及呈现设备(39)以及用于操纵内容数据和相关元数据的应用程序。 根据预定义的数据访问格式设置组织的访问策略,并且具有用于控制对呈现设备的资源的访问以及所述内容数据和相关元数据的访问参数。 在根据组织的访问策略访问呈现设备的资源的同时执行符合组织访问所述数据的访问策略的组织应用(35)。 根据本发明,维护用户访问策略,其限制组织应用相对于组织的访问策略访问呈现设备的资源。 基于额外的信任数据来调整用户访问策略,用于选择性地允许组织应用根据组织的访问策略访问资源。 因此,用户控制应用程序对渲染设备的资源的访问。

    • Providing entry points for 3D video data is described; an entry point unit (18) generates an entry point table by defining entry points in an incoming 3D video data stream and storing entry point addresses giving the location of the defined entry points; the video data stream comprises a multitude of sub-streams, which multitude encodes one stream of 3D 5 video data and comprises at least one 2D sub-stream that independently encodes a 2D version of the 3D video data and at least one auxiliary sub-stream that dependently encodes part of the 3D video data; the entry points include main entry points in the 2D sub-stream and auxiliary entry points in the auxiliary sub-stream for enabling 3D trickplay of the 3D video data by retrieving and decoding non-adjacent fragments of the 2D sub-stream and retrieving 10 and dependently decoding corresponding fragments of the auxiliary sub-stream.
    • 描述3D视频数据的入口点; 入口单元(18)通过定义输入3D视频数据流中的入口点并存储给定定义入口点的位置的入口点地址来生成入口点表; 视频数据流包括多个子流,其多个编码一个3D 5视频数据流,并且包括独立地编码3D视频数据的2D版本和至少一个辅助子流的至少一个2D子流 它依赖地编码3D视频数据的一部分; 入口点包括二维子流中的主入口点和辅助子流中的辅助入口点,用于通过检索和解码2D子流的非相邻片段来实现3D视频数据的3D特技播放,并且检索10和 依赖地解码辅助子流的相应片段。

    • A method (1) of transmitting interactive television, whereby interactive television applications are transmitted inside application-modules. These modules are transmitted in a broadcast stream. Recording systems cannot decide which modules are to be recorded. Therefore storage related information of said modules is signalled in the broadcast stream. Module identification information related is implemented in the Application Information Table (AIT) and/or in the Download Information Indication (DII) message. Thus information is included in the broadcast stream concerning categories stating whether application modules are mandatory, optional or forbidden to record. Alternatively properties of a module are chosen from Code/Data/Both and/or Fixed/Variable. Recording systems use this information do decide if application modules are to be recorded or disregarded. Alternatively, application module identification information is transmitted in said broadcast stream. A module identification number is used to avoid multiple recordings. Application modules having the same category are preferably grouped together.
    • 一种发送交互式电视的方法(1),由此在应用模块内传输交互式电视应用。 这些模块以广播流传输。 记录系统无法决定要记录的模块。 因此,所述模块的存储相关信息在广播流中被通知。 相关的模块识别信息在应用信息表(AIT)和/或下载信息指示(DII)消息中实现。 因此,关于涉及应用模块是强制性的,可选的或被禁止记录的类别的广播流中包括信息。 或者,代码/数据/两者和/或固定/变量都选择模块的属性。 记录系统使用这些信息确定应用程序模块是要被记录还是被忽略。 或者,在所述广播流中发送应用模块识别信息。 模块识别号用于避免多次录音。 具有相同类别的应用模块优选地被分组在一起。
