    • 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。
