[0033] In this embodiment, the playback interface for the target
disc is established according to the disc information list, the
playback sequence list, and the chapter information list in step
13.
[0034] With reference to FIG. 3, when the target disc is a
menu-based target disc, such as a HD DVD-Video or a BluRay DVD
movie, the playback interface includes a hierarchical playback
menu. In this embodiment, the hierarchical playback menu is
three-layered, and step 13 includes the following sub-steps:
[0035] In step 131, it is first determined whether combined size of
the contents of the original discs exceeds storage capacity of the
target disc with reference to the disc playback durations of the
original discs recorded in the disc information list. When the
result reveals that the combined size of the contents of the
original discs is within the storage capacity of the target disc, a
first layer submenu of the hierarchical playback menu is
established according to the disc information list. In this
embodiment, the first layer submenu includes first options that are
respectively named after the disc titles, but is not limited
thereto in other embodiments of the present invention. In the
exemplary hierarchical playback menu shown in FIG. 4, the first
layer submenu includes two options that are respectively named "New
York Trip" and "Paris Trip".
[0036] In step 132, a second layer submenu of the hierarchical
playback menu is established according to the playback sequence
list. In this embodiment, the second layer submenu includes second
options that are respectively named after sequence numbers of the
sequences of the original discs, but is not limited thereto in
other embodiments of the present invention. In the example shown in
FIG. 4, the hierarchical playback menu includes two of the second
layer submenus. The first one of the second layer submenus includes
three options, namely "S1-1", "S1-2" and "S1-3", while the second
one of the second layer submenus includes two options, namely
"S2-1" and "S2-2".
[0037] In step 133, a third layer submenu of the hierarchical
playback menu is established according to the chapter information
list. In this embodiment, the third layer submenu includes third
options that are respectively named after chapter numbers of
chapters included in the sequences of the original discs, but is
not limited thereto in other embodiments of the present invention.
In the example shown in FIG. 4, the hierarchical playback menu
includes five of the third layer submenus. A first one of the third
layer submenus includes three options, namely "ch1-1-1", "ch1-1-2"
and "ch1-1-3", a second one of the third layer submenus includes
two options, namely "ch1-2-1" and "ch1-2-2", a third one of the
third layer submenus includes two options, namely "ch1-3-1" and
"ch1-3-2", a fourth one of the third layer submenus includes two
options, namely "ch2-1-1" and "ch2-1-2", while a fifth one of the
third layer submenus includes two options, namely "ch2-2-1" and
"ch2-2-2".
[0038] In step 134, an activation command is set for a first option
of the first layer submenu to correspond to a respective second
layer submenu. In this embodiment, an activation command is set for
each of the first options of the first layer submenu to correspond
to a respective one of the second layer submenus. In the exemplary
hierarchical playback menu shown in FIG. 4, an activation command
is set for the first option named "New York Trip" to correspond to
the first one of the second layer submenus, and an activation
command is set for the first option named "Paris Trip" to
correspond to the second one of the second layer submenus.
[0039] In step 135, an activation command is set for a second
option of the second layer submenu to correspond to a respective
third layer submenu. In this embodiment, an activation command is
set for each second option of each of the second layer submenus to
correspond to a respective one of the third layer submenus. In the
exemplary hierarchical playback menu shown in FIG. 4, activation
commands are respectively set for the second options of the first
one of the second layer submenus to correspond to the first to
third ones of the third layer submenus, while activation commands
are respectively set for the second options of the second one of
the second layer submenus to correspond to the fourth and fifth
ones of the third layer submenus.
[0040] In step 136, an activation command is set for a third option
of the third layer submenu to correspond to a respective chapter of
a respective sequence of a respective one of the original discs. In
this embodiment, an activation command is set for each of the third
options of each of the third layer submenus to correspond to a
respective chapter of a respective one of the sequences of a
respective one of the original discs. In the exemplary hierarchical
playback menu shown in FIG. 4, activation commands are respectively
set for the third options of the first one of the third layer
submenus to correspond to the 1.sup.st, 2.sup.nd and 3.sup.rd
chapters of the 1.sup.st sequence of the 1.sup.st original disc.
Activation commands are respectively set for the third options of
the second one of the third layer submenus to correspond to the
1.sup.st and 2.sup.nd chapters of the 2.sup.nd sequence of the
1.sup.st original disc. Activation commands are respectively set
for the third options of the third one of the third layer submenus
to correspond to the 1.sup.st and 2.sup.nd chapters of the 3.sup.rd
sequence of the 1.sup.st original disc. Activation commands are
respectively set for the third options of the fourth one of the
third layer submenus to correspond to the 1.sup.st and 2.sup.nd
chapters of the 1.sup.st sequence of the 2.sup.nd original disc.
Activation commands are respectively set for the third options of
the fifth one of the third layer submenus to correspond to the
1.sup.st and 2.sup.nd chapters of the 2.sup.nd sequence of the
2.sup.nd original disc.
[0041] In step 137, the chapter contents of the original discs and
the playback menu are encoded.
[0042] In step 138, the encoded data is outputted to the target
disc.
[0043] With reference to FIG. 5, when the target disc is a
script-based target disc, such as an iHD or a BluRay DVD Java, the
playback interface includes a script-structure playback interface,
and step 13 includes the following sub-steps:
[0044] In step 141, a script is established according to the disc
information list, the playback sequence list and the chapter
information list. An exemplary script is illustrated in FIG. 6.
[0045] In step 142, a disc-information processing program is added
into the script. The disc-information processing program is
triggerable to jump to a playback sequence frontpage that
corresponds to a selected one of the original discs (e.g., "New
York Trip" and "Paris Trip"). The playback sequence frontpage may
include sequence options, such as S1-1, S1-2 and S1-3 for "New York
Trip", and S2-1 and S2-2 for "Paris Trip".
[0046] In step 143, a playback-sequence processing program is added
into the script. The playback-sequence processing program is
triggerable to jump to a chapter information frontpage that
corresponds to a selected sequence (e.g., S1-1, S1-2, S1-3, S2-1
and S2-2) of a selected one of the original discs. The chapter
information frontpage may include chapter options, such as ch1-1-1,
ch1-1-2 and ch1-1-3 for the sequence "S1-1", ch1-2-1 and ch1-2-2
for the sequence "S1-2", etc.
[0047] In step 144, a chapter processing program is added into the
script. The chapter processing program is triggerable to jump to a
selected chapter (e.g., ch1-1-1, ch1-1-2, ch1-1-3, ch1-2-1, etc.)
of a selected sequence of a selected one of the original discs.
[0048] In step 145, the chapter contents of the original discs and
the script are encoded.
[0049] In step 146, the encoded data is outputted to the target
disc.
[0050] With reference to FIG. 2, the second preferred embodiment
differs from the first preferred embodiment in that sub-step 123 is
omitted, i.e., there is no chapter information list. In other
words, the analysis results are stored in the disc information list
and the playback sequence list only. Therefore, in step 13 (refer
to FIG. 1), the playback interface for the target disc is
established according to the disc information list and the playback
sequence list.
[0051] Consequently, when the target disc is menu-based, the
hierarchical playback menu is two-layered. In particular, with
reference to FIG. 7, sub-steps 133 and 136 of the first preferred
embodiment (refer to FIG. 3) are omitted in the second preferred
embodiment. Further, in sub-step 135' of the second preferred
embodiment, instead of setting an activation command for a second
option of the second layer submenu to correspond to a respective
third layer submenu, an activation command is set for a second
option of the second layer submenu to correspond to a respective
sequence of a respective one of the original discs. In addition, in
sub-step 137' of the second preferred embodiment, the sequence
contents, instead of the chapter contents, of the original discs
are encoded along with the playback menu.
[0052] On the other hand, with reference to FIG. 8, when the target
disc is script-based, the script is established according to the
disc information list and the playback sequence list in sub-step
141' of the second preferred embodiment. In sub-step 143' of the
second preferred embodiment, the playback-sequence processing
program is triggerable to jump to a playback sequence that
corresponds to a selected sequence of a selected one of the
original discs. Further, sub-step 144 of the first preferred
embodiment is omitted in the second preferred embodiment. Moreover,
in sub-step 145' of the second preferred embodiment, the sequence
contents of the original discs are encoded along with the
script.
[0053] The computer-readable recording medium according to the
present invention includes program instructions for causing a
computing apparatus to execute consecutive steps of the
machine-implemented method for establishing a playback interface
for a target disc when storing contents of a plurality of original
discs into the target disc. The machine-implemented method may be
one of the first and second preferred embodiments.
[0054] In sum, the present invention provides a machine-implemented
method for establishing a playback interface for a large-capacity
target disc when it is demanded to store contents of a plurality of
small-capacity discs into the large-capacity target disc.
[0055] While the present invention has been described in connection
with what are considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiments but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretation so as to encompass all such modifications and
equivalent arrangements.
