`
`
`
`apparatus which reproduces data recorded in a recording
`
`
`medium such as a 3D—ROM.
`

`
`[0002]
`
`Recently,
`
`a disc reprodtction apparatus has become
`
`widespread in household—use for a large capacity disc
`
`
`
`
`
`having stored high—definition and high-sound-quality
`
`
`
`information with an advanced interactive function.
`
`[0003]
`
`A representative disc reproductior apparatus among
`
`
`
`them is a 3lu—ray Disc (hereinafter referred to as a
`
`
`
`"33") apparatus.
`
`
`
`A 33 is provided wit? a huge data
`
`
`
`capacity: 25 gigabytes (GB)
`
`
`in a single layer and 50 G3
`
`
`
`in a dial layer, and can store high definition movie
`
`
`conceno. Commercia"y available or rertal—use packaged
`
`
`
`
`
`
`
`
`
`so_,ware using the %) is supplied as a %)—ROM (jlue—ray—
`
`
`
`
`
`
`
`
`
`Read—Only—Memory)
`
`that is a read—only media in which data
`
`is written in the course 0: manufacture and which is no:
`
`
`
`
`
`recordable and not rewritable.
`
`[0004]
`
`
`
`For the 3
`
` D-ROM,
`
`two modes of
`
`specifications have
`
`been developed: High
`
`Disc Java ( a
`
`
`D—J) mode.
`
`
`Blu—Ray

`Versatile
`
`
`Disc Read Only Memory
`
`
`
`(DVD—ROM), and high definicion video and high quality
`
`
`
`
`
`aJdio are available.
`It is noted that content
`
`
`
`
`
`
`
`specification of a %)—<OM is similar to that of a DVD—ROM.
`
`
`
`
`
`i1 addition to the HDMV mode, visual
`
`
`:n the 3D—J mode,
`
`
`
`
`
`represeqtation such as a superimposed video can be added
`
`by a Java (registered trademark) application.
`
`[0005]
`
`
`
`
`
`In the case of a conventional DVD, when a menu is
`
`
`called during reproduction of the main part,
`
`the
`
`reproduction is interrupted, and a menu screen is
`
`A "pop—up menu" adopted
`
`displayed on the whole screen.
`
`
`
`
`by a %) does not interrupt reproduc:ion of the main part
`
`
`
`
`
`and a :ranslucent menu screen appea_s in a "pop—up
`
`manner" over the reproduction screen.
`
`[0006]
`
`
`
`Most of HDMV mode titles are provided with such a
`
`pop—up menu.
`
`
`In the pop—up menu,
`
`there are provided
`
` functions such as move to top menu,
`
`transition to
`
`reproduction position, and change in voice/subtitle
`
`stream.

`application, which is a Java (registered trademark)
`
`
`
`application. Hereina:

`
`the pop—up menu in the HDMV
`
`
`
`
`mode and the graphic menu in the %)—0 mode displayed by
`
`
`
`
`the %)—0 application are collectively referred to as a
`
`fter,
`
`
`
`pop—Jp menu.
`
`[0008]
`
`
`
`There are provided user interfaces, such as a
`
`
`reproduction button and a stop button, as part of
`
`
`functions 0: a disc reproduction apparatus. Powever,
`
`
`
`
`
`
`
`
`these are dif'erent

`
`[Technical Problem]
`
`[0011]
`
` In conventional
`
`techniques,
`
`a user operates a remote
`
`
`controller or the like to display a user interface and a
`
`pop—up menu on a screen. However, since the pop—up menu
`
`
`
`
`has its displayed position and form predefined for each
`
`title,
`
`the user interface and the pop-up menu may be
`
`
`
`overlapped when they are displayed.
`
`[0012]
`
`r S
`
`
`
`he user cannot determine only by seeing the screen
`
`
`whether a displayed menu is a user interface or a pop—up
`
`
`menu. Therefore,
`
`
`the user may be confused about which
`
`menu display on the screen the user should look at to
`
`
`
`perform an operation, and even the user may perform a
`
`
`
`wrong operation.
`
`[0013]
`
`
`Especially,
`
`
`in the case 0; a car navigation system
`
`
`
`the
`
`which is Jsed in an in-vehicle environment,
`
`
`
`per"orming a wrong operation is higher
`
`
`
`possibilioy o
`
`because it is operated mainly with a touch panel. That
`
`
`each button of a user interface and a pop—up menJ
`
`is, since a touch panel is operated by directly touching
`
`
`
`
`
`displayed on a screen, an action which is not
`
`intended by
`
`
`
`
`the user may be invoked i: a wrong button is pressed by
`
`mistake.
`
`[0014]
`
`Since the pop—up menu is displayed being overlapped
`
`on a title reproduction screen,
`
`the user commonly
`
`performs a operation of displaying the pop—up menu in a
`
`state that only the title reproduction screen is
`
`
`
`
`
`
`
`displayed.
`
`
`
`
`
`
`
`In tris case, since a renote controller is
`
`
`provided witq the dedicated buttons for realizing the
`
`
`
`user interface and pop-up menu uncc‘ons in conventional
`
`
`
`
`
`techniques,
`
`
`the user can press a button for the operation
`
`which the user desires.
`
`[0015]
`
`However,
`
`
`in th cas
`wh rc the us r op rat s a touch
`
`
`
`
`
`
`panel
`
`in the state that only the title reprodJction
`
`screen is displayed, it is nOt possible to determine
`
`
`
`
`
`which menu the user wants to display by operating the
`
`
`screen of the touch panel, and the user interface and
`
`pop-up menu functions cannot be realized.
`
`[0016]
`
`
`in the HDMV mode, it is possible to,
`Furthermore,
`
`wh n th us r pr ss s a button via the touch panel,
`
`
`execute the user's operation of the button on the basis
`
`
`
`
`
`
`o:
`
`
`the coordinate information about
`
`the button and the
`
`pressed position. However, since the graphics menu in
`
`
`
`
`
`
`
`the %)—u mode is realized by the %)—u application, button
`
`
`
`position information does not exist unlike the HDMV mode,
`
`
`
`
`
`and the graphics menu does not respond to a touch panel
`
`operation.
`
`[0017]
`
`
`The present invention has been made to solve the
`
`conventional problems as described above.
`
`
`A first object
`
`
`of the present invention is to provide a disc
`
`
`reproduction apparatus capable of appropriately
`
`
`
`
`displaying a pop-up menu specific to HDMV mode and BD—J
`
`
`mode titles and a user interface to reduce operatioq
`
`
`
`mistakes.
`
`[0018]
`
`
`A second object o:
`
`the present invention is to
`
`
`provide a disc reproduction apparatus capable 0:, even
`
`
`when a user performs a operation via a touch panel during
`
`reproduction of a title, realizing pop—up menu and user
`
`
`interface funccions without especially preparing pop—up
`
`
`
`menu and user interface operation buttons.
`
`[0019]
`
`Furthermore,
`
`
`a third object o:
`
`the present invention
`
`is to provide a disc reproduction apparatus capable o:
`
`I
`
`
`
`
`even when a user performs a operation via a touch panel,
`
`
`enabling the user to op rat
`th pop up m nu in the HDMV
`
`
`
`mode and the graphics menu in the BD—J mode similarly.
`
`
`
`[Solution to Problem]
`
`[0020]
`
` In order to solve the above problems,
`
`
`
`reproduction apparatus according to a first invention has
`
`a disc
`
`
`
`a signal processing section accepting a user's operation
`
`
`and displaying a pop—up menu and a user interface
`
`specific to a title being reproduced by a reproduction
`
`section, on a monitor; wherein, upon accepting a user's
`
`operation to display the pop—up menu or the user
`
`interface,
`
`the signal processing section causes the
`
`
`monitor to display only any of the pop—up menu and the
`
`
`user interface.
`
`[0021]
`
`A disc reproduction apparatus according to a second
`
`invention has a signal processing section accepting a
`
`user's operation onto a touch panel integrated with a
`
`monitor and displaying, on the monitor, a pop—up menu and
`
`
`a user interface specific to a title being reproduced by
`
`a reproduction section; wherein
`
`when the user touches the touch panel,
`
`the signal
`
`processing section causes the monitor to display the pop—
`
`up menu upon determining that the pop-up menu can be
`
`
`displayed, and displays the user interface on the monitor
`
`upon determining that the pop-up menu cannot be displayed.
`
`[0022]
`
`Furthermore,
`
`a disc reproduction apparatus according
`
`to a third invention has a signal processing section
`
`accepting a user's operation onto a touch panel
`
`
`
`
`
`integrated with a monitor; and Jpon receiving a mouse
`
`
`
`
`
`event error from a %)—u application a_ter a user's
`
`
`
`operation onto the touch panel is notified to the BD—J
`
`
`
`
`
`
`
`application as a mouse event,
`
`the signal processing
`
`
`
`section issues VK_POPUP_MENU to the BD—J application.

`"ects o
`'nvention]
`
`[0023]
`
`
`According to the first invention, it is possible to
`
`
`provide a disc reproduction apparatus capable of reducing
`
`operation mistakes because any 0: a pop-up menu and a
`
`
`
`
`user interface specific to HDMV mode and BD-J mode titles
`
`
`
`is displayed on a screen.
`
`[0024]
`
`According to the second invention, a pop—up menu and
`
`a user interface are displayed being given priority
`
`
`
`d gr
`
`s wh n th us r p rforms a operation on the touch
`
`
`
`panel during reproduction of a title. Therefore, it is
`
`
`possible to realize the functions of the pop—up menu and
`
`
`the user interface without especially preparing pop—up
`
`
`
`menu and user interface operation buttons.
`
`[0025]
`
`Furthermore, according to the third invention, since
`
`
`a mouse event 0:
`
`
`
`
`the BD-J applicatioq is used for

`
`
`operation 0" a graphics menu in the BD—J mode, it is
`
`
`
`possible to operate a pop—up menu and a graphics menu
`
`
`
`
`similarly even in the case 0 per’orming a operation via
`
`the touch panel.

`[0028]
`
`[First embodiment]
`
`
`Figure l is a block diagram 0“ a disc reproduction
`
`
`apparatus according to an embodiment of the present
`
`
`
`invention.
`
`A disc reproduction apparatus 100 is
`
`
`
`
`constituted by a pickup 11 which acquires data from a s)—
`
`
`
`
`ll
`
`ROM 10,
`
`a servo 12 which controls the pickup ll, a local
`
`
`storage l3, a network interface 14, a signal processing
`
`section l5, a reproduction section 16 and a memory 19.
`
`
` The signal processing section 15 includes a pop—up menu
`
`detection section 17 and a user operation section 18.
`
`[0029]
`
`Next, each component will be described.
`
`[0030]
`
`
`
`
`The %J—ROM 10 is a recording medium in which AV
`
`contents such as a movie or a liv vid 0 are r cord d.
`
`
`
`
`
`
`
`
`
`The %)—ROM 10 is often used for package software to be on
`
`
`the market or for rental, and it is a read—only medium in
`
`
`which data is written during a manufacture process and
`
`for which data addition and rewriting is impossible.
`
` :003l]
` The servo L2 is a device which causes tre pickup ll
`
`
`to move
`
`(seek)
`
`toward the radius direction of a recording
`
`medium or adjus:s the movement
`
`recording medium toward the axia' direction 0” the
`
`recording medium.
`
`[0032]
`
`
` The pickup ll acquires various data from the BD—ROM
`
`
`
`
`
`10 and sends the data to the signal processing section 15.
`
`[0033]
`
` Data processed by the signal processing section 15
`
`
`
`includes not only the data in the BD—ROM 10 but also data
`
`
`
`
`(focusing) o;
`
`the
`
`
`
`
`
`
`
`12
`
`
`stored in the local storage 13 and data downloaded from a
`
`
`network via the network interface 14.
`
`[0034]
`
`
` The signal processing section 15 is means for
`
`processing these data so that the reproduction section 16
`
`
`
`can reproduce AV contents and the like.
`
`The signal
`
`
`processing section 15 receives the contents of a user's
`
`operation, d t rmin s wh th r the op ration is acceptable,
`
`
`and, if acceptable, causes the user operation section 18
`
`
`
`The signal processing section
`to execute the operation.
`
`
`
`
`15 also has a function 0" displaying a user interface
`
`
`which is originally incorporated in the memory 19 o:
`
`the
`
`disc reproduction apparatus 100 onto a monitor 43 as
`
`shown in Figure 4.
`
`[0035]
`
`
`A user interface is such that a program is held in
`
`the memory 19 to display, on the monitor, a reproduction
`
`
`
`button o_ a stop button as functions of the disc
`
`
`
`
`
`reproduCtion apparatus 100 43 or the like. When a user
`
`operates a remote controller 45 or a touch panel 46 as
`
`shown in Figure 4,
`
`the signal processing section 15
`I]
`
`
`
`associates the user's operation with the function 0'
`
`button and causes the user operation section 18 to
`
`
`execute the action of the operated button.

`
`The monitor 43 is a device

`
`
`It also displays operation menus such as a pop—up

`
`
`
`
`may be attached on the display screen of

`
`
`Here, a display example of the pop—up menu will be

`
`
`On a reproduction screen where multiple c‘rcular

`
`
`objeCts are depicted, as shown in Figure 5A,
`

`
`operates a pop—up menu key with the remote controller or

`
`a pop—up menu example 50 is displayed on
`
`in Figure 5B.
`
`
`
`In the pop—up menu example 50, buttons for
`
`
`performing a user's operation are prepared, and a
`

`
`According to the pop-up menu example 50, main

`
`
`
`
`Figure 6 is a diagram showing a process flow in the
`
`
`
`per”orming a operation using the remote
`
`case 0
`
`controller in this embodiment. First, at step 60,
`
`the
`
`
`user operates a pop—up menu button of the remote
`
`controller 45.
`
`[0055]
`
`At step 61, upon determining that it is possible to
`
`display a pop—up meni
`
`the reproduction seCtion 16,
`
`in the title being reproduced by
`
`
`
`the signal processing
`
`section 15 proceeds to step 62. On the other hand, upon
`
`
`
`determining that it is not possible to display a pop—up
`
`meni
`
`in the title being reproduced by the reproduction
`
`the signal processing section 15 displays
`
`
`
`seCtion 16,
`
`
`
`
`
`
`
`
`
`that it is not possible to perform a pop—up menu
`
`
`operation, on the monitor 43 o_ the like to nOtify it to
`
`
`
`the user
`
`(step 65).
`
`
`
`It is also possible for tte signal
`
`processing section 15 to ignore a user's operation and
`
`invokes no action at Step 65.
`
`
`
`[0056]
`
`
`
`At step 62, when confirming that a user interface is
`
`displayed on the monitor 43,
`
`the signal processing
`
`
`
`section 15 deletes the display of the user interface
`
`
`(step 64). Then,
`
`the signal processing section 15
`
`proceeds to step 63.
`
`
`On the other hand, when confirming
`
`
`
`20
`
`
`that a user interface is not displayed on the monitor 43,
`
` the signal processing section 15 immediately proceeds to
`
`step 63.
`
`[0057]
`
`At step 63,
`
`the sigra; processing section 15
`
`displays a pop—up menu of
`
`the title being reproduced by
`
`
`
`
`
`the reproduction section 16, on the monitor 43 and ends
`
` the process.
`
`[0058]
`
`
`
`
`
`The procedure for the user to display a pop-up menu
`
`using the remote controller 45 has been described.
`
`in
`
`
`
`the case 0: displaying a user interface, a process can be
`
`
`performed in the above procedure,
`
`in which the pop—up
`
`
`menu and the user interface are exchanged.
`
`[0059]
`
`
`
`
`Thus, any of the pop—up menu and the user interface
`
`is displayed on the monitor 43, it is possible to reduce
`
`operation errors.
`
`[0060]
`
`
`Next, description will be made with the use 0;
`
`Figure 7 on an action invoked when the user touches the
`
`touch panel 46 in order to display a pop—up menu in the
`
`
`HDMV mode.
`
`[0061]
`
`
`Figure 7 is a diagram showing a process flow in the
`
`
`
`
`per"orming a operation using the touch panel
`
`in
`
`case 0
`
`this embodiment. When the user touches the touch panel
`
`
`
`21
`
`46 (step 70),
`
`the signal processing section 15 determines
`
`whether there is a button at the screen position where
`
`
`the user has performed the operation. Upon determining
`
`that a button exists (Step 71),
`
`
`
`
`
`the signal processing
`
`
`
`
`seCtion l5 proceeds to step 72.
`
`
`button "or performing a user's operation,
`
`
`The button may be any
`
`including a
`
`
`pop—up menu and a user interface.
`
`[0062]
`
`At step 72,
`
`the user operation seCtion 18 to execute the user's
`
`the signal processing section 15 causes
`
`
`
`
`operation of the button at the position where the user
`
`
`_ a button does rot exist at the position
`
`pressed.
`
`
`
`whcrc thc JSCI prcsscd thc touch panel 46, it is assumed
`
`
`
`that the user has touched the touch panel 46 by mistake
`
`or pressed a wrong place.
`
`
`In this case, it is desirable
`
`that the user's operation is ignored or a user interface
`
`
`
`is displayed.
`
`[0063]
`
`Upon determining that there is not a button at step
`
`71,
`
`the signal processing section 15 proceeds to step 73.
`
`[0064]
`
`At step 73,
`
`the signal processing section 15
`
`determines whether it is possible to display a pop—up
`
`menu in the title being reproduced by the reproduction
`
`
`
`
`
`
`"f determiring that it is not possible to
`section 16.
`
`display a pop—up menu,
`
`for example, because a pop—up menu
`
`does not exist in the title being reproduced,
`
`the signal
`
`
`
`
`
`22
`
`processing section 15 proceeds to step 74. Whether a
`
`pop—up menu exists or not is held in management
`
`
`
`information in a ****.c]ipi “1'e shown in Figure 2, and
`
`the signal processing section 15 can check this
`
`
`information.
`
`[0065]
`
`At step 74, because it is supposed that the user has
`
`
`
`touched the touch panel 46 in order to perform some
`
`operation, even in the case where it is no: possible to
`
`display a pop-up menu,
`
`the signal processiqg section 15
`
`
`may display a user interface on the monitor 43. Since it
`
`is conceivable that the user has touched the touch panel
`
`46 by mistake, it is also possible to ignore the user's
`
`
`
`
`
`operation.
`
`[0066]
`
`
`On the other hand, if determining that it is
`
`possible to display a pop—up menu in the title being
`
`_eproduced by the reproduction section 16, at step 73,
`
` :he signal processing section 15 causes a pop-up menu to
`
`be displayed on the monitor 43
`
`(step 75).
`
`[0067]
`
` Thus,
`
`in accordance with the sequence in Figure 7,
`
`there is also an advantage that, since the user can cause
`
`a user interface to be displayed by touching a position
`
`where a button does not exist if he wants to execute an
`
`action which does not exist in the pop—up menu,
`
`the user
`
`
`
`can continue the operation.
`
`
`
`23
`
`[0068]
`
`Furthermore, by using the sequence in Figure 7, it
`
`
`is possible to perform a operation in the priority order
`
`
`0: a button operation,
`
`
`a pop—up menu and a user interface
`
`in response to a touch panel operation by the user, and
`
`
`
`reduce wrong operations by the user because a pop—up menu
`
`
`and a user interface are nOt overlappedly displayed.
`
`
`
`[0069]
`
` The procedure for displaying a pop-up menu and a
`
`
`
`
`user interface in tie HDMV mode has been described above.
`
`However,
`
`in order to display a pop—up menu by a touch
`
`
`panel operation in a RD—J mode title,
`
`a process described
`
`
`with reference to Figire 8
`
`is required.
`
`
`
`
`
`[0070]
`
`
`
`
`n a %)—u mode title also, it is possible to display
`
`a pop—up Henu at step 63 in Figure 6 and step 75 in
`
`
`
`Figure 7 by the process described below.
`
`[0071]
`
`
`
`As for a pop—up menu in the BD—J mode, when an
`
`
`
`
`
`
`operatioq of POPUP_ON by the user is noti"ied so the jJ—d

`
`
`most of contents, and the pop—up menu is displayed
`
`
`similarly to a pop—up menu in the HDMV mode when seen
`
`from the user.
`
` :0072]
`
`
`
`24
`
`
`In order to display this pop—up menu,
`
`a mouse event
`
`supported by contents is used.
`
`A mouse event is to
`
`detect a mouse click or a moase press and invoke an
`
`
`aCtion registered with the BD—J application.
`
`A pop—up
`
`
`
`
`
`menu is displayed by the squence in Figure 8 with the
`
`
`
`use of this function.
`
`[0073]

`
`Figure 8 is a diagram showing a process t'ow in the
`
`
`
`
`
`
`case 0“ operat‘ng the pop-up menu 0'
`a %)—J title using
`
`
`
`the touch panel
`
`in this embodiment. Here, description
`
`will be made on the assumption that contents are provided
`
`
`with a BD—J application which supports a mouse event and
`
`
`
`
`VK_POPU? MENU.
`
`[0074]
`
`When detecting a touch panel operation by the user
`
`(step 80),
`
`the signal processing section 15 issues a
`
`
`
`
`mouse press to the %)—0 application (step 81).
`
`[0075]
`
`
`
`
`At step 82, VKiPOPUPiMENU is issued to the BD—J
`
`application.
`
`[0076]
`
`
`
`
`
`Whether a mous prcss ov nt rogist r d with the %)—0
`
`application exists or not can be added to the
`
`
`determination at Step 61 in Figure 6 and Step 73 in
`
`Figure 7 about whether it is possible to display a pop—up
`
`menu or not. When there is a registered mouse press
`
`
`
`
`event, it is determined that the %)—0 application will
`
`
`
`25
`
`
`
`
`
`need some different action and VK_POPUP_M?NU of step 82
`
`is not issued. When there is not a registered mouse
`
`press event, VK_POPUP_M:
`
` Lil
`
`
`
`NU is issued to the BD—J
`
`application by a touch panel operation (step 82).
`
` Thereby, it does not happen that the mouse press event
`
`
`
`registered with the BD—J application is executed by
`
`mistake in the processing at step 63 in Figure 6 and step
`
`75 in Figure 7.
`
`[0077]
`
`As described above, according to the above-stated
`
`she first embodiment o;
`
`
`
`
`disc reproduCtion apparaous of
`
`
`
`
`
`
`
`the present invention, it is possible to reduce operation
