摘要： The present invention relates to a method and apparatus of determining arrival time of data packet when a digital broadcast data stream is recorded. According to the present invention, two program clock reference values are extracted from a transport packet sequence, an average packet interval time is obtained based on both the difference between the two program clock reference values and the number of packets between two packets from which the two program clock reference values are extracted, and an arrival time of each packet between the two packets is determined by t(0)+I*t_av, where t_av is the average packet interval time, t(0) is the program clock reference value of the preceding one among the both packets, and I is an index indicative of the order of packet between the both packets.

摘要： A structure of navigation information for video data recorded on a recording medium and recording and reproducing methods and apparatuses using the structure. The method of recording video data in accordance with the present invention records video data on a recording medium with organizing the video data into navigation units and interleaving navigation units of different reproduction paths with one another in multiple reproduction path segments. An information entry is created for each navigation unit and the information entry comprises information indicating whether the associated-navigation unit is in a multiple reproduction path segment and information for identifying the reproduction path to which the associated navigation unit belongs.

摘要： The present invention relates to editing data streams recorded in a recording medium. At the time of deleting an arbitrary navigation unit from a data stream partitioned by the navigation units and recorded in a recording medium, information is recorded in the recording medium, which, in a recording block including both remaining data belonging to the deleted navigation unit and valid data belonging to the navigation unit right before the deleted navigation unit, the information is used for distinguishing the valid data from the remaining data. By referring to the information afterwards, the remaining data can be prevented from being decoded.
摘要翻译：本发明涉及编辑记录在记录介质中的数据流。在从由导航单元分割并记录在记录介质中的数据流中删除任意导航单元时，将信息记录在记录介质中，该记录介质包括属于删除的导航单元的两个剩余数据和在删除的导航单元之前属于导航单元的有效数据，该信息用于将有效数据与剩余数据区分开。通过参考该信息，可以防止剩余的数据被解码。
