Abstract
Abstract A method and device for interleaving bit stream by which multimedia data including digital picture data, audio data, and sub-video signals are seamless-reproduced by smoothly switching videos and voices to each other without disturbing videos, allowing noise to be contained in voices, and discontinuing voices at angle switching sections during multi-angle reproduction from an optical disk on which multi-media data are recorded. A multi-angle system stream is constituted of a plurality of system streams composed of picture data and audio data created at different viewing points. In the multi-angle system stream from which a system stream corresponding to an angle can be reproduced at every predetermined unit by freely switching the system stream to another during reproduction, the display time of picture data contained in the system stream corresponding to a angle and the display time of audio data are made equal to each other for every angle at every prescribed unit at which the angle can be switched.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
An interleaving method which for the presentation
of a bitstream that is reproduced by selecting two or more
data units (VOB) from a bitstream comprising three or more
data units (VOB) contiguous on the same time-base is
characterized by generating said bitstream by arranging the
selected data units (VOB) in a particular sequence on the
same time-base based on the presentation time of each data
unit (VOB) so that it is possible to sequentially access
all data units (VOB) and present only the selected data
units (VOB) without time-base intermittence, and is
characterized by dividing said data units (VOB) into
shortest-read-time data units (ILVU), and generating said
bitstream by arranging the shortest-read-time data units
(ILVU) in a particular sequence on the same time-base based
on the shortest read time each shortest-read-time data unit
(ILVU) so that it is possible to sequentially access all
shortest-read-time data units (ILVU) and present only the
shortest-read-time data units (ILVU) of the selected data
units (VOB) without time-base intermittence, said
presentation time of each shortest-read-time data unit
(ILVU) being the same.

same audio data.
Claim 3
Dependent Claim
