Description

  The present invention relates to a disc playback apparatus for playing back data recorded on a recording medium such as a BD-ROM, and more particularly to pop-up menu display.

  2. Description of the Related Art In recent years, disk playback devices that play back large-capacity disks that record information with high image quality, high sound quality, and advanced interactive functions have become popular in general households.

  A typical disc playback device is a Blu-ray Disc (BD: Blu-ray Disc, hereinafter referred to as “BD”). The BD has a huge data capacity of 25 GB (GB: Giga Byte) with a single layer and 50 GB with two layers, and can store movie content with high-definition image quality. This commercial and rental package software using BD is provided by BD-ROM (Blu-ray-Read-Only-Memory), which is a read-only medium in which data is written during the manufacturing process and cannot be added or rewritten. ing.

  This BD-ROM has two specifications, HDMV mode and BD-J mode. The HDMV mode is an extension of the video and audio codec specifications over the conventional DVD-ROM, and can use high-definition video and high-quality audio. The content specification is the same as that of the DVD-ROM. In the BD-J mode, in addition to the HDMV mode, a visual expression such as superimposing images can be added by a Java (registered trademark) application.

  Here, in the case of a conventional DVD, when a menu is called during the main part reproduction, the reproduction is interrupted and the menu screen is displayed on the entire screen. The “pop-up menu” adopted in the Blu-ray Disc is used to develop a semi-transparent menu screen in a “pop-up type” over the playback screen without interrupting the main-frame playback.

  Many titles in the HDMV mode are provided with this pop-up menu, and are provided with functions such as moving to the top menu, changing the playback position, and changing audio and subtitle streams.

  Also, in the title of the BD-J mode, a graphics menu that has almost the same form displayed on the screen as the HDMV title pop-up menu is realized by a BD-J application that is a Java (registered trademark) application. Hereinafter, the HDMV mode pop-up menu and the BD-J mode graphics menu displayed by the BD-J application are collectively referred to as a pop-up menu.

  Note that although there are user interfaces such as a play button and a stop button as functions of the disc playback device, they are different from the pop-up menu described above. Pop-up menus are those that are inherently held by BD-ROM HDMV mode and BD-J mode titles, that is, information relating to pop-up menus is held on a disc such as a BD-ROM, and each title has its own function. is there.

  In addition, a dedicated button that realizes functions of a user interface and a pop-up menu is provided on the remote control or the like, and the user can display the menu by pressing the button (see, for example, Patent Document 1).

JP 2004-304767 A

  In car navigation systems and the like used in an in-vehicle environment, operation using a touch panel is the mainstream. Since the pop-up menu is displayed so as to overlap the title reproduction screen, the user usually performs an operation for displaying the pop-up menu in a state where only the title reproduction screen is displayed.

  In the conventional technology, since the remote control has dedicated buttons for realizing the functions of the user interface and the pop-up menu, the user only has to press the button that the user wants to operate.

  However, when the user operates the touch panel while only the title playback screen is displayed, it is impossible to determine which menu the user wants to display and operated the touch panel screen. The menu function cannot be realized.

  The present invention has been made in order to solve the conventional problems. When a user operates the touch panel during playback of a title, the pop-up menu and the user interface operation button are not specially prepared. It is another object of the present invention to provide a disc reproducing apparatus capable of realizing a user interface function.

  In order to solve the above problems, the present invention accepts a user operation on a touch panel integrated with a monitor, and a signal processing for displaying a pop-up menu specific to the title being played back by the playback means and a user interface on the monitor. And when the user touches the touch panel, the signal processing means displays the pop-up menu on the monitor when determining that the pop-up menu can be displayed, and determines that the pop-up menu cannot be displayed. Is displayed on a monitor.

  According to the present invention, when the user operates the touch panel during playback of the title, the pop-up menu and the user interface are displayed with priority, so that the pop-up menu and the user interface operation buttons are not specially prepared. Pop-up menu and user interface functions can be realized.

  In the following, description will be given with reference to FIG. 1 which is a block diagram of a disc playback apparatus 100 according to the present embodiment.

  The disc playback apparatus 100 includes a pickup 11 that acquires data from the BD-ROM 10, a servo 12 that controls the pickup 11, a local storage 13, a network interface 14, a signal processing unit 15, a playback unit 16, and a memory 19. The signal processing means 15 includes a pop-up menu detection means 17 and a user operation means 18.

  Next, each configuration will be described.

  The BD-ROM 10 is a recording medium on which AV contents such as movie works and live video are recorded. The BD-ROM 10 is often used for commercial or rental package software, and is a read-only medium in which data is written in the manufacturing process and cannot be additionally written or rewritten.

  The servo 12 is a device that moves the pickup 11 in the radial direction of the recording medium (seek) and adjusts the movement (focus) of the recording medium in the axial direction.

  The pickup 11 acquires various data from the BD-ROM 10 and sends the data to the signal processing means 15.

  The data processed by the signal processing unit 15 includes not only data of the BD-ROM 10 but also data stored in the local storage 13 and data downloaded from the network via the network interface 14.

  The signal processing means 15 is a means for processing these data so that the reproduction means 16 can reproduce AV contents and the like. Further, the signal processing means 15 receives the contents of the user operation, determines whether or not the operation can be accepted, and causes the user operation means 18 to execute the operation if it can be accepted. Further, it has a function of displaying a user interface built in the memory 19 of the disc playback apparatus 100 from the beginning on the monitor 43 shown in FIG.

  Here, the user interface is a program that is stored in the memory 19 and displays a playback button, a stop button, and the like as functions of the disc playback apparatus 100 on the monitor 43 and the like. When the user operates the remote controller 45 or the touch panel 46 shown in FIG. 4, the signal processing unit 15 combines the user operation with the function of each button, and causes the user operation unit 18 to execute the operation of the operated button.

  The pop-up menu detection unit 17 is included in the signal processing unit 15 and has a function of detecting whether a pop-up menu is displayed.

  Next, the file structure of the BD-ROM 10 will be described with reference to FIG.

FIG. 2 is a diagram showing the configuration of the BD-ROM 10. The BD-ROM 10 has a recording area that spirals from the inner periphery to the outer periphery in the same manner as other optical discs such as a DVD (Digital Versatile Disc) and a CD (Compact Disc). A logical address space in which logical data can be recorded during the lead-out. In addition, inside the lead-in, BCA (Burst Cutting)
There is a special area called Area) that can only be read by the drive. Since this area cannot be read from the application, it is used for copyright protection technology, for example.

  In the logical address space, application data such as video data is recorded with file system information (volume) at the head. The file system is UDF, ISO9660, or the like, and logical data recorded in the same way as a normal PC can be read out using a directory and file structure. A file name of 255 characters The directory name can be read out.

  The directory and file structure on the disc of the BD-ROM 10 are the BDMV directory and bd. A cert file is placed. The BDMV directory is a directory in which data such as AV contents handled by the BD-ROM 10 and management information is recorded. bd. cert (fixed file name) is a certificate used for signature verification when merging content added for a virtual package with data on the BD-ROM 10.

  Under the BDMV directory, there are five subdirectories called PLAYLIST directory, CLIPINF directory, STREAM directory, BDJO directory, and JAR directory. The BDMV directory includes an index. bdmv, MovieObject. Two types of bdmv files are arranged.

  Here, the index. The bdmv (file name fixed) will be described. index. bdmv is management information relating to the entire BD-ROM 10, and is an organization ID (32 bits) that is an identifier that identifies a provider of movie works, a disc ID (128 bits) that is an identifier assigned to each BD-ROM 10 provided by the provider, and the like. After inserting the disc into the disc playback apparatus 100, the index. By reading bdmv first, the disc playback apparatus 100 uniquely recognizes the disc. In addition, index. bdmv includes a table in which a plurality of titles that can be reproduced on the BD-ROM 10 and BD-J objects that define individual titles are associated with each other.

  Next, a file with the extension “bdjo” will be described.

A file with the extension “bdjo” is a file storing a BD-J object. The BD-J object is information that defines a title by associating an AV stream indicated by PlayList information with an application. The BD-J object indicates an “application management table” and a list of PlayLists that can be reproduced in the title. The application management table (AMT) is a table that realizes “application signaling”. “Application signaling” refers to control that manages the title in the BD-ROM 10 as the life of the application and controls the start and end of the application. Here, the life interval indicates a time interval in which the application can live on the heap memory of the virtual machine on the time axis of the entire content recorded in the BD-ROM 10. “Survival” means that the application has been read into the heap memory and can be executed by the virtual machine. The application management table shows an application having this title as a life cycle by listing an application identifier (application ID) and an ID of a Java (registered trademark) archive file belonging to the application. That is, one application is composed of one or more Java (registered trademark) archive files.

  A Java (registered trademark) application whose sector is managed by the application management table in the BD-J object in this way is referred to as a “BD-J application”.

  FIG. It is a figure which shows the relationship between a bdmv file and a title. A title is a playback unit that combines an application and an AV stream. The bdmv file describes the title structure on the disc, and refers to each title on the disc and the corresponding application (BD-J application for the BD-J mode title, scenario program for the HDMV mode title). I manage the relationship. In addition, “First Playback” and “Top Menu” exist as special titles. “First Playback” is a title that is automatically played back first when the BD is activated. It is mainly used for BD usage agreement display. “Top Menu” is played when the menu key of the remote controller is pressed or when the title reproduction is finished, and is mainly used for selecting a title and selecting a subtitle / audio language.

  Here, FIG. 4 shows an example of a usage pattern of the disc playback apparatus 100 according to the present embodiment as a system. For example, the disc playback apparatus 100 is configured with a BD-ROM 10, a removable medium 42, a monitor 43, a WWW server 44, and a remote controller 45.

  The monitor 43 is a device that displays reproduced video. In addition, an operation menu such as a pop-up menu and a user interface is displayed to the user. Therefore, the user can visually operate the disc playback apparatus 100 using the remote controller 45. A touch panel 46 may be attached on the display screen of the monitor 43 so that the user can operate it. At this time, the signal processing means 15 detects the position on the screen where the user touches the touch panel 46 with a finger or the like, and performs various user operations corresponding to the pop-up menu and the user interface buttons displayed at the position on the screen. The user operation means 18 can also be executed.

  The remote controller 45 is a device for remotely operating the disc playback apparatus 100 by a user. The user can play back the content recorded on the BD-ROM 10 by operating buttons on the remote controller 45 or the disc playback apparatus 100.

  Here, a display example of the pop-up menu will be described with reference to FIG.

  In the reproduction screen on which a plurality of circular objects shown in FIG. 5A are drawn, the user operates a pop-up menu key with a remote controller or the like. Then, the pop-up menu example 50 is displayed on the monitor 43 on the screen being reproduced as shown in FIG. In the pop-up menu example 50, buttons for user operations are prepared, and the currently selected button is highlighted by the highlight 51.

  According to the pop-up menu example 50, the main functions that can be operated by the user include changing the title being played, switching the language of audio and subtitles, changing chapters, etc., and can incorporate functions that the user wants to operate during playback. It is.

  Next, processing when the user operates using the remote controller 45 to display a pop-up menu in the HDMV mode will be described with reference to FIG.

  In step 60, the user operates the pop-up menu button on the remote controller 45.

  In step 61, if the signal processing means 15 determines that the pop-up menu can be displayed in the title being reproduced by the reproducing means 16, the process proceeds to step 62. On the other hand, when the signal processing means 15 determines that the pop-up menu cannot be displayed in the title being reproduced by the reproducing means 16, the signal processing means 15 displays on the monitor 43 or the like that the pop-up menu operation is not possible and notifies the user (step 65). In step 65, the user operation can be ignored by the signal processing means 15, and nothing can be performed.

  In step 62, when it is confirmed that the user interface is displayed on the monitor 43, the signal processing means 15 deletes the display of the user interface (step 64). Thereafter, the process proceeds to step 63. On the other hand, when the signal processing means 15 confirms that the user interface is not displayed on the monitor 43, the signal processing means 15 proceeds to step 63 as it is.

  In step 63, the signal processing means 15 displays a pop-up menu of the title being reproduced by the reproducing means 16 on the monitor 43, and ends the processing.

  In the foregoing, the procedure for the user to display the pop-up menu using the remote controller 45 has been described. When displaying the user interface, the above-described procedure may be performed by replacing the pop-up menu with the user interface.

  As described above, since either the pop-up menu or the user interface is displayed on the monitor 43, an operation error can be reduced.

  Next, an operation when the user touches the touch panel 46 in order to display a pop-up menu in the HDMV mode will be described with reference to FIG.

  When the user touches the touch panel 46 (step 70), the signal processing means 15 determines whether or not a button exists at the screen position operated by the user. When the signal processing unit 15 determines that the button exists (step 71), the process proceeds to step 72. The button may be a button for performing a user operation including a pop-up menu and a user interface.

  In step 72, the signal processing means 15 causes the user operation means 18 to execute the user operation of the button at the location pressed by the user.

  If the signal processing unit 15 determines in step 71 that there is no button, the process proceeds to step 73.

  In step 73, the signal processing means 15 determines whether or not a pop-up menu can be displayed in the title being reproduced by the reproducing means 16. If the signal processing means 15 determines that the pop-up menu cannot be displayed because the pop-up menu does not exist in the title being played back, the process proceeds to step 74. Since the presence / absence of the pop-up menu is held in the management information of the *****. Clpi file in FIG. 2, the signal processing means 15 may confirm this information.

  In step 74, even if the pop-up menu cannot be displayed, it is expected that the user has touched the touch panel 46 to perform some operation. Therefore, the signal processing means 15 displays the user interface on the monitor 43. May be. Note that it is possible that the user accidentally touched it, so that the user operation can be ignored.

  On the other hand, in step 73, when the signal processing means 15 determines that the pop-up menu can be displayed in the title being reproduced by the reproducing means 16, the signal processing means 15 displays the pop-up menu on the monitor 43 (step 75).

  As described above, according to the sequence of FIG. 7, when the user wants to execute an operation that does not exist in the pop-up menu, the user interface is displayed by touching a portion where the button does not exist. The user can continue to operate.

  Further, if the sequence of FIG. 7 is used, it is possible to operate in the priority order of the button operation, the pop-up menu, and the user interface with respect to the touch panel operation of the user, which is very easy to use.

  Next, a processing flow when the priority order of the pop-up menu and the user interface is reversed with respect to the operation when the user touches the touch panel 46 will be described with reference to FIG.

  When the user touches the touch panel 46 (step 80), the signal processing means 15 determines whether or not a button exists at the screen position operated by the user. When the signal processing unit 15 determines that the button exists (step 81), the signal processing unit 15 proceeds to step 82. The button may be a button for performing a user operation including a pop-up menu and a user interface.

  In step 82, the signal processing means 15 causes the user operation means 18 to execute the user operation of the button at the location pressed by the user. If there is no pop-up menu or user interface button at the location where the user presses the touch panel 46, it is assumed that the user has touched it by mistake or has made a wrong location. In this case as well, similar to the description of FIG. 7, the operation may be ignored or the user interface may be notified that the operation is invalid.

  In step 81, if the signal processing means 15 determines that there is no button at the screen position operated by the user, the process proceeds to step 83.

  In step 83, the signal processing means 15 displays a user interface on the monitor 43.

  In the process of FIG. 8, the user interface is displayed on the monitor 43, but the user may want to operate a pop-up menu.

  If the user interface displayed on the monitor 43 has a button for displaying a pop-up menu, the signal processing means 15 can display the pop-up menu on the monitor 43 by operating the button.

In such a case, a process for displaying the pop-up menu on the monitor 43 will be described with reference to FIG.

  When the user operates a button for displaying a pop-up menu in the user interface (step 90), the process proceeds to step 91.

  In step 91, the signal processing means 15 determines whether or not a pop-up menu can be displayed with the title being reproduced. In step 91, if the signal processing means 15 determines that the pop-up menu cannot be displayed with the title being played back, the request for pop-up menu display is ignored or a warning that the pop-up menu cannot be displayed using the user interface is issued. It is preferable.

  If the signal processing means 15 determines in step 91 that the pop-up menu can be displayed with the title being played back, the signal processing means 15 first deletes the user interface (step 92). This is because if the pop-up menu is displayed with the user interface being displayed, the user interface and the pop-up menu may overlap each other.

  In step 93, the signal processing means 15 displays a pop-up menu on the monitor 43.

  8 and 9, the priority order of the user interface and the pop-up menu can be switched in the opposite manner to the sequence of FIG.

  In the above, the display procedure of the pop-up menu and the user interface in the HDMV mode has been described. However, in order to display the pop-up menu by the touch panel operation with the title of the BD-J mode, the processing described in FIG. 10 is necessary.

  In the title of the BD-J mode, the step 63 in FIG. 6, the step 75 in FIG. 7, and the step 93 in FIG. 9 can display a pop-up menu even in the title of the BD-J mode by the processing described below. Become.

  The pop-up menu in the BD-J mode displays the pop-up menu when the user's operation POPUP_ON is notified to the BD-J application as VK_POPUP_MENU. This function is displayed in the same way as a pop-up menu in the HDMV mode when viewed from the user, and is included in most contents.

  In order to display this pop-up menu, a mouse event supported by the content is used. The mouse event is an operation that detects a mouse click or a mouse press and performs an operation registered in the BD-J application.

  Using this function, a pop-up menu is displayed in the sequence of FIG. Here, a description will be given assuming that the content includes a BD-J application that supports a mouse event and VK_POPUP_MENU.

  When the signal processing means 15 detects the touch panel operation of the user (step 100), it issues a mouse press to the BD-J application (step 101).

  In step 102, VK_POPUP_MENU is issued to the BD-J application.

  It should be noted that in step 61 in FIG. 6, step 73 in FIG. 7, and step 91 in FIG. 9, whether or not a pop-up menu can be displayed is added with the presence or absence of a mouse press event registered in the BD-J application. Good. When the mouse press event is registered, the BD-J application determines that some other operation is performed, and does not issue VK_POPUP_MENU in step 82. If the mouse press event is not registered, VK_POPUP_MENU is issued to the BD-J application by touch panel operation (step 82). By doing so, the mouse press event registered in the BD-J application is not erroneously executed in the process of step 63 in FIG. 6, step 75 in FIG. 7, and step 93 in FIG.

  As described above, even when the user operates the touch panel during the playback of the HDMV mode title and the BD-J mode title, the pop-up menu and the user interface operation buttons are not specially prepared. A user interface function can be realized.

  As described above, the disk reproducing apparatus according to the present invention is useful as a disk reproducing apparatus for reproducing data recorded on a recording medium such as a BD-ROM disk.
