    • The DVD Stream Recording standard defines application pack-ets (AP_PCK) as the logically smallest units created from the input data stream during recording. Usually the conver-sion from a point on the time axis to a corresponding appli-cation packet is realised by using a mapping list available in the navigation data. However, depending on the target time and a Stream Object selected, the match found can vary significantly. A method is proposed that allows editing a recorded stream of application packets with higher precision. The stream comprises at least a first application packet having a first arrival time stamp (APAT) and a subsequent second application packet having a second arrival time stamp (APAT). For editing the recorded stream a discrete time is input that is a start time or an end time and has a value between the first arrival time stamp and the second arrival time stamp. The discrete time is mapped onto the first or the second arrival time stamp, and the recorded stream is edited correspondingly.
    • DVD流记录标准将应用程序包(AP_PCK)定义为在记录期间从输入数据流创建的逻辑最小单位。 通常,通过使用导航数据中可用的映射列表来实现从时间轴上的点到相应的应用分组的转换。 但是,根据目标时间和所选择的流对象,找到的匹配值可能会有很大差异。 提出了一种允许以更高精度编辑记录的应用分组流的方法。 流包括至少具有第一到达时间戳(APAT)的第一应用分组和具有第二到达时间戳(APAT)的后续第二应用分组。 为了编辑记录的流,输入作为开始时间或结束时间的离散时间,并且具有在第一到达时间戳和第二到达时间戳之间的值。 将离散时间映射到第一或第二到达时间戳,并且记录的流被相应地编辑。
