摘要:
A video object is recorded on an optical disc. The video object is composed of at least one video object unit, and each video object unit contains control information and video data and has a presentation time of one second or shorter. The control information relates to display control and copying control for the video object unit.

An optical disc including: a data area storing one or more video objects; and a time map area storing time map information. Each video object includes a plurality of video object units. The time map information includes a first time table and a second time table for each video object. Each first time table includes: addresses of video object units in a corresponding video object; and indicators. The addresses are arranged in order and indicate storage positions of the video object units that correspond to reproduction points that differ by a predetermined time unit. The predetermined time unit is longer than a maximum reproduction period of a video object unit. The indicators specify the video object units which respectively correspond to the addresses. Each second time table includes an entry for each video object unit in the corresponding video object. The entries are arranged in order. Each second time table includes a reproduction period and a data size of each video object unit.

The invention provides an information recording medium such as an optical disk, having a large capacity and being capable of performing read/write operations at high speeds. The recording medium includes audio stream prepared for after-recording data, and a audio attribute information having a bit rate information to the recorded audio stream as a management information. A recorder according to the invention has a check unit for checking, in advance, the possibility of after-recording operation of the recorder to the audio stream to be after-recorded with reference to the bit rate information of the audio attribute information.

An information recording medium suitable for optical discs such as DVD-RAM is provided for integrated management of data as objects in different kinds of AV formats. Also apparatus is provided for data recording and playing to the medium. The medium stores management information including program chain information (PGC information) defining the playback order of the objects, and object information containing information relevant to the objects. The object information has general information of the object, attribute information and a map associating a playback time point of the object with an address on the optical disc of a component of the object to be played. The PGC information has cell information including information about type of object, identification information. The order of the cell information in the PGC information corresponds to the order in which the objects are played back.

The present invention provides a bitstream generation apparatus that enables an efficient editing of video objects in providing a finished audio video production. Audio and video data is encoded and an elementary encode unit correlates the audio and video data into video objects. The video objects can be assembled by an editing unit into a desired scenario of reproduction. An editor can re-arrange the scenes that are formed by the video objects with the assistance of a correction unit and an interleaving unit that can divide the pieces of audio data and the pieces of video data that form the video objects into new video objects which can be interleaved into the reproduction order of video objects without requiring a re-encoding of the entire set of video objects that constitute sequences of scenes for the audio video product.
