When trick play modes are implemented using a lookup table
cross-referencing content divided into sectors of specific size with
content encoding unit information, an accurate playback start time code
cannot be detected because the total content playback time is not clear.
A trick play method for digital storage media used to record and
reproduce multimedia content resolves this problem and enables random
access playback, fast-forward play, fast-reverse play and other trick
play modes from any desired position in the content by recording program
content segmented into media object units, each recorded as a separate
file; recording a program manager file containing a media object
information table; recording a media object information file containing
playback time information and entry points at a specific time interval
for each media object, and recording a playlist manager file containing a
table of user-specified playback start program IDs and playback start
time and end time information.
