摘要:
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.

摘要:
Optical discs formatted to record plural audio streams of different content for reproduction with a single video stream can result in audio output of content unexpected by the user depending upon the audio stream configuration contained in the AV stream reproduced. This can confuse and cause the user to change the audio output after reproduction starts. To prevent this, information indicating the type of audio stream configuration contained in each AV stream on the optical disc is stored with each audio stream. This audio stream type information is presented to the user on the same screen from which an AV program is selected for playback. The use can thus know before playback starts what audio stream channel is preselected for playback, and can change the audio channel as desired before payback starts.

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 an 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.

A video object is recorded on an optical disc. The video object comprises 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.

摘要:
An optical disc that is reproducible by a reproducing apparatus has a still picture data and an audio data which are reproduced simultaneously. The still picture data is stored in a video part stream (ST1) comprising a plurality of units, and the audio data is stored in a second system stream (ST2) comprising one or a plurality of units. The units store time stamp information so that the second system stream (ST2) follows immediately after the video part stream (ST1). By changing the data in the second system stream (ST2), the audio data presented with a still picture can be freely and easily changed even after recording the still picture data using an MPEG standard format.
