Abstract: A recording medium, method and apparatus for recording digital data streams are provided. The method includes recording a received digital data stream of data packet units by grouping the data packet units into an object, and creating and recording a managing information for the object. The managing information can include entry information associated with an entry point of the digital data stream and information indicating whether or not the entry information exists.

Abstract: A method and apparatus are provided for creating and recording management information for digital data streams, and for reproducing data using the management information. According to an embodiment, the method for recording a digital data stream being received, comprising: (a) recording received stream units of a digital data stream along with their arrival time references representing the arrival times of the received stream units on a recording medium; (b) grouping the received stream units into stream object units of a predetermined size, such that the maximum search time for a stream object unit is almost uniform among the recorded stream object units; and (c) creating and recording reproduction management information regarding the stream object units.

Abstract: A method and apparatus for recording time information for received digital data streams are provided. The method includes recording first time information and second time information on a recording medium. The first time information is part of management data for managing presentation data and the second time information is time information of the presentation data. The format of the first time information coincides with the format of the second time information.

Abstract: A method and apparatus are provided for creating and recording management information for digital data streams, and for reproducing data using the management information. The method for reproducing data from a recording medium includes receiving an access time for accessing data from the recording medium, searching for a target entry point based on the access time by using access time entries, and searching for a target object unit by using the target entry point and object unit entries. The access time entries and the object unit entries are management information stored on the recording medium.

Abstract: A recording medium, method and apparatus for recording digital data streams are provided. The method includes recording a received digital data stream of data packet units by grouping the data packet units into program units, and creating and recording entry information pertaining to entry points of the digital data stream.

Abstract: A recording medium, method and apparatus for providing management information are provided. The method includes grouping data of a digital data stream into a plurality of object units, and creating map information for accessing the data, wherein the map information includes time information and object unit information associated with the object units.

Abstract: The present invention relates to method and apparatus of recording a multi-channel data stream on a recording medium in such a manner that substreams of digital channels constituting the multi-channel data stream can be distinguished each other in reproduction. The present recording method records a multi-channel stream composed of substreams belonging to plural selected channels on a recording medium, unitizes the recorded stream to a single stream object, creates a piece of search information for each substream contained in the recorded multi-channel stream, and records the created plural pieces of search information on the recording medium. The present method makes it possible to selectively search and reproduce each substream among a multi-channel stream recorded on a recording medium, thereby improving use convenience of a recording machine such as a digital video recorder.
