    • 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。

    • The invention relates to a system for recording a signal. A recorder (200) comprises a receiver (201) for receiving a source signal (101) having associated first play time information such as a Normal Play Time timeline. The receiver (200) is coupled to a recording controller (203) which generates a recorded signal (301) from the source signal (101). The recorded signal (301) comprises a recording discontinuity with respect to the source signal (101) caused by for example the recording being paused in a time interval. The recording controller (203) is coupled to a storage medium (205). The recorder (200) further comprises a time processor (209) for generating second time information for the recorded signal (301) in response to the first play time information and the recording discontinuity. The second time information may for example be a compensated NPT timeline or event descriptors or stream events having time indications modified to correspond to the recorded signal (301).
    • 本发明涉及用于记录信号的系统。 记录器(200)包括用于接收具有相关联的第一播放时间信息(例如正常播放时间时间线)的源信号(101)的接收器(201)。 接收器(200)耦合到从源信号(101)产生记录信号(301)的记录控制器(203)。 所记录的信号(301)包括关于源信号(101)的记录不连续性,例如由时间间隔暂停的记录引起的。 记录控制器(203)耦合到存储介质(205)。 记录器(200)还包括响应于第一播放时间信息和记录不连续性而产生记录信号(301)的第二时间信息的时间处理器(209)。 第二时间信息可以例如是补偿的NPT时间线或事件描述符或具有修改为对应于所记录的信号的时间指示的事件描述符或流事件(301)。

    • A method (49, 55) of handling fonts in a recorder or a playback-recorder for interactive television. Fonts are stored on a recordable storage medium (220), wherein the fonts are part of a downloaded interactive television application. When recording, the downloaded fonts are stored separate from the application, preferably in a font library on the recordable storage medium, which preferably is a removable medium, preferably an optical storage medium. Each font is only stored in one copy, even when a plurality of applications on the storage medium need that font for running. When playing back the application from the storage medium, indicating information is provided on which fonts form the storage medium in the font library are required for playback of said application from said storage medium. Thus multiple storage of fonts is prevented, minimising needed storage space on the storage medium.
