  Conventionally, in a device having a function of reproducing video and sound based on data acquired from a recording medium such as a CD (Compact Disc) and a DVD (Digital Versatile Disc) and a medium such as a broadcast wave, a reproducing function for each medium Is a mode, and each playback function is managed based on a mode switching operation. Specifically, in accordance with the operation of ejecting the disc or the like as the recording medium, the disc playback mode is automatically changed to a preset mode or a mode executed immediately before disc playback (so-called last mode). Mode management is performed so as to switch automatically. In particular, in-vehicle content playback apparatuses often use such a mode management technique. With such a mode management technique, a user simply performs the operation of ejecting the currently-viewed disc. In addition, it is possible to immediately start viewing the reproduced video and audio regarding other functions such as navigation.

  Here, Blu-ray Disc (registered trademark; hereinafter referred to as “BD”) is an HDMV (HDV) that is an extension of the conventional method used in DVDs as a method for controlling playback of video and audio based on recorded data. In addition to the High Definition Movie (control) method, a BD-J (Blu-ray Disc Java (registered trademark)) control method that executes a Java (registered trademark) program and controls playback content may be used. In such a BD-J title controlled using a Java program, the content can be made more interactive or the content can be expressed in various ways according to the user operation, compared to a conventional DVD or the like. Is possible. In such BD-J titles, unlike conventional CDs and DVDs, the disc itself is removed from the playback device for the purpose of continuously providing content based on the program or waiting for subsequent disc insertion. Some are intended to continue execution of the Java program even if they are removed.

For this reason, in the conventional method of managing each playback function based on the mode switching operation,
There is a possibility that the execution of the Java program to be continuously executed is forcibly terminated and shifts to another mode. In such a case, control as expected by the content producer is performed in content control when a subsequent disc is loaded or in execution of a Java program created so that the content can be enjoyed even after the disc is ejected. It will not be.

  In view of the above-described problems, the present invention is a content playback system in which video and audio playback is controlled using a program read from a recording medium such as a BD, and the recording medium is ejected during execution of such a program. Even in such a case, it is an object to provide a function according to the intention of the producer of the recording medium, if necessary, while providing a function equivalent to the mode management in the conventional reproducing apparatus.

  In order to solve the above-described problems, the present invention determines whether or not a program being executed is to be continuously executed when a disc ejection operation is detected, and is a program to be continuously executed. Provides the same function as mode management in a conventional playback device by continuing program execution and terminating the program execution and switching to another mode if the program is not continuously executed. When necessary, it is possible to provide a behavior that is in line with the intention of the producer of the recording medium.

  Specifically, the present invention is a control device for a content reproduction system that reproduces content based on data acquired from at least one of a plurality of types of media, and a program for controlling the reproduction of the content. The recorded recording medium can be loaded and unloaded, is connected to a reading device that reads data from the loaded recording medium, and the content read by executing the program read from the recording medium by the reading device And when the discharge operation is detected by the discharge operation detecting means, the discharge operation detecting means for detecting that the discharge operation of the recording medium from the reading device has been performed. In addition, the program being executed is a continuation program for being continuously executed even after the recording medium is ejected. Program determining means for determining whether or not the program is a continuation program, the reproduction control by execution of the program is stopped, and any one of the plurality of types of media excluding the recording medium Playback control switching means for switching playback control by starting playback control of content based on data acquired from a medium, and when it is determined that the program is a continuation program, the continuation This is a control device in which reproduction control is continued by executing a program.

  A control device according to the present invention is a control device for a content reproduction system that reproduces content including at least one of video and audio generated based on data acquired from at least one of a plurality of types of media. is there. Here, in addition to recording media such as CDs, DVDs, and BDs, various types of media such as TV broadcast waves, radio broadcast waves, and the Internet can be used to obtain various data for generating video and sound. Media shall be included.

  Here, the recording medium is preferably a portable recording medium such as a BD (so-called removable medium), but the present invention is also applicable to a recording medium that is not portable. As an example of a recording medium in which playback of video and sound is controlled by executing a control program recorded on the recording medium, BD can be cited as an example. Any method can be applied as long as video and audio reproduction are controlled by executing a control program recorded together with data, and the method is not limited to BD.

The content reproduction system according to the present invention is a predetermined recording medium (in the present embodiment, in which content including video and audio and a program for controlling reproduction of the content are recorded among the plurality of types of media. Means for controlling content reproduction based on data obtained from other media (hereinafter referred to as first reproduction control means) except for BD41), and a program read from the predetermined recording medium (this embodiment) Then, means for controlling content reproduction by executing the BD-J program (hereinafter referred to as second reproduction control means) is provided.

  The program for controlling the playback of content is a program for controlling the playback content, the playback order of content, and the like in playback of video and audio, and data for generating video signals and audio signals. It is distinguished from itself. For example, the program is a content control program for controlling reproduction of content recorded together with the program on the recording medium and read by the reading device. The second playback control means controls playback of video and audio by executing this control program. The control program is, for example, a BD-J program for controlling a BD-J title recorded on a BD, is managed as a process (task) by a CPU (Central Processing Unit) or a program execution environment, and is defined in the program. It is controlled by using variables and stacks.

  The present invention determines the type of program being executed by the program determination means when an operation of ejecting the recording medium on which the program being executed is recorded from the reading device, and according to the result of this determination, Management of reproduction control different from conventional mode management is performed. Specifically, the present invention determines whether or not the program being executed is a continuation program when a discharging operation is detected, and if it is determined that the program is not a continuation program, the program is executed. Playback control (playback control by the second playback control means) is stopped, and content playback control (first playback control means) based on data acquired from any one of a plurality of types of media other than the recording medium Playback control), the same function as conventional mode management (a method of automatically switching to another mode when the disc is ejected) is provided to the user, while the control program being executed is If it is determined that it should be continuously executed, the control program is continuously executed without starting the reproduction control by the first reproduction control means, and the intention of the producer is Tsu behavior is intended to enable the. In the present invention, the discharge of the recording medium refers to the entire operation of removing the recording medium from the reading device, and not only the recording medium is discharged by the discharging mechanism provided in the reading device but also by the manual operation of the user. The removal of the recording medium is also included.

Here, the Index table has a list of titles in a format such as First Playback, Top Menu, Title1, Title2, and the like, and information indicating whether each title is an HDMV title or a BD-J title (hereinafter, BD-J title). This information is referred to as a “content control method identification flag”). By referring to the content control method identification flag, it can be determined whether the title related to reproduction is an HDMV title or a BD-J title.

  If the title related to playback is an HDMV title, MovieObject is selected, and PlayList, TopMenu, Title, etc. are controlled using Navigation Command as in the case of conventional DVD video. When the title related to reproduction is a BD-J title, BD-J Object is selected and the Java program included in this BD-J Object (corresponding to the content control program of the present invention. Hereinafter, BD). (Referred to as -J program), PlayList, TopMenu, Title, and the like are controlled. Note that the BD-J program controls the playback content by specifying an ID assigned to PlayList or the like. The BD-J title includes an interactive title and a movie title, which can be determined by referring to the title playback type recorded on the BD 41. The interactive content is interactive content in which the playback state of the content is changed by a user operation, and examples thereof include a game whose playback content and result are changed by a user operation.

  The BD-J title reproduced in the present embodiment is controlled by executing a BD-J program recorded on the BD 41 together with the content. More specifically, the BD-J program is managed as a process (task) by the OS (Operating System) or execution environment of the system, is assigned an execution area, and is processed using a stack, a variable, or the like. .

  FIG. 3 is a diagram showing an outline of a functional configuration of the content reproduction system 1 according to the present embodiment. In the system according to the present embodiment, the CPU 11 interprets and executes the content reproduction program developed in the RAM 12 or the ROM 14, so that the video and audio based on the data acquired from the medium using the control method corresponding to the medium are included. Each playback control unit that controls at least one playback (BD-J title playback control unit 22, HDMV title playback control unit 23, DVD playback control unit 24, CD playback control unit 25, digital TV playback control unit 26, AM / FM reproduction control unit 27 and navigation reproduction control unit 28), a loading / discharging detection unit 34 for detecting that a loading operation or a discharging operation of the BD 41 with respect to the multi-drive 4 has been performed, and the start of each reproduction control unit Executed by the playback control management unit 21 that manages the stop and the like, and the BD-J title playback control unit 22 A program determination unit 31 that determines whether or not the BD-J program to be executed is a program that continues to be executed even after the BD 41 is discharged, a setting content acquisition unit 32 that acquires the setting content stored in the HDD 13, A video output unit 35 that outputs the video signal generated by the playback control unit, an audio output unit 36 that outputs the audio signal generated by each of the playback control units, and a user via a touch panel display, various buttons, and the like It functions as a content reproduction system 1 including an input receiving unit 37 that receives input contents and a disc determination unit 33 that determines whether or not a disc loaded in the multi-drive 4 is a subsequent BD 41.

  The playback control management unit 21 corresponds to the playback control switching means of the present invention. Among the playback control units, the HDMV title playback control unit 23, the DVD playback control unit 24, the CD playback control unit 25, and the digital TV playback control. Unit 26, AM / FM playback control unit 27 and navigation playback control unit 28 correspond to the first playback control means of the present invention, and BD-J title playback control unit 22 corresponds to the second playback control means of the present invention. It corresponds to.

Each reproduction control unit reproduces content using a control method corresponding to the content acquired from the corresponding medium. For example, when the content read from the BD 41 is the HDMV title, the HDMV title playback control unit 23 controls the playback of the content according to the HDMV command, and the content read from the BD 41 is the BD-J title. The BD-J title playback control unit 22 controls the playback of content by executing the BD-J program read from the same BD41. In the present embodiment, the playback control management unit 21 refers to the content control method identification flag recorded on the BD 41, so that the content to be played back (the content that is being played or is about to be played) Is an HDMV title or a BD-J title.

  Among the playback control units, the BD-J title playback control unit 22 executes the BD-J title read from the BD 41 to control playback of the BD-J title, thereby playing back the BD-J title. To control. Here, the BD-J program executed by the BD-J title playback control unit 22 may remain on the RAM of the content playback system 1 even after the disc on which the program has been recorded is ejected. There is something intended. Whether or not the BD-J program is to be executed even after the disc is ejected can be determined by referring to the contents of the BD-J program.

  Hereinafter, the content of the reproduction control switching process (mode switching process) in the present embodiment will be described using a flowchart. FIG. 4 is a flowchart showing the flow of the playback control switching process associated with the disc ejection according to the present embodiment. The processing shown in this flowchart is started when a discharge operation of the BD 41 is performed during the reproduction of the content based on the BD 41 loaded in the multi-drive 4. Note that the processing order of the playback control switching processing according to the present invention can be changed as appropriate in accordance with the embodiment, and the processing order is not limited to the examples shown below.

  In step S101, a discharge operation of the BD 41 is detected. The loading / ejecting detection unit 34 detects that the user has performed a disk ejection operation on the multi-drive 4 via a touch panel display or buttons, or the multi-drive 4 has been ejected to eject a disk. Detect that. Thereafter, the process proceeds to step S102.

  In the present embodiment, when the ejection operation is performed, a signal for instructing the multi-drive 4 to eject the disk is given, and the multi-drive 4 receiving this instruction ejects the loaded BD 41. Here, the timing for instructing the multi-drive 4 to eject the disk and actually ejecting the disk may be immediately after the ejection operation detected in step S101. For example, in steps S104 and S111 described later, Other timings such as before and after the indicated process may be used.

  In step S102, it is determined whether or not the playback control performed at the time of the ejection operation is playback control by the BD-J title playback control unit 22. The playback control management unit 21 determines whether or not the BD-J program related to the ejected BD 41 is executed at the time when the eject operation of the BD 41 is detected in step S101, that is, the reproduced title is BD-J. It is determined whether it is content. If it is determined that the reproduced title is a BD-J title and is controlled by the BD-J program, the process proceeds to step S103. If it is determined that the reproduced title is not a BD-J title and the BD-J program is not executed (that is, the reproduced title is an HDMV title or the like), the process proceeds to step S111.

In step S103, it is determined whether or not the BD-J program executed by the BD-J title playback control unit 22 is a continuous program that is continuously executed even after the BD 41 in which the program has been recorded is discharged. . When it is determined in step S102 that the BD-J program is being executed, the program determination unit 31 is intended to continue execution of the executed BD-J program even after the disc is ejected. Determine if it is a program. Since the BD-J program intended to be continuously executed includes information indicating that this program is to be continuously executed even after the disc is ejected, the program determination unit 31 is executing By referring to the contents of the BD-J program, it can be determined whether or not the BD-J program being executed is a continuation program. If it is determined that the BD-J program intended for continuous execution is being executed, the process proceeds to step S104. If it is determined that the BD-J program is being executed but is not a continuation program, the process proceeds to step S111.

  In step S104, the execution of the BD-J program that has been executed before the discharging operation of the BD 41 is continued. That is, when a discharge operation of the BD 41 is detected, but reproduction control is performed by executing the BD-J program, and the BD-J program being executed is a continuation program, Execution is continued, and function mode switching (reproduction control switching) is not performed as in the conventional mode management method. For this reason, the touch panel display 2 and the speaker 3 continue to perform output controlled by the BD-J program that has been executed before the BD 41 is ejected. For example, when the BD-J program that has been executed before the ejecting operation of the BD 41 is a game or the like, the output content is an image or sound for the game or the like, and is executed before the ejecting operation of the BD 41. If the stored BD-J program is a content that spans a plurality of BDs 41, it is video or audio that includes a message prompting the subsequent disc to be loaded. In step S104, the execution of the BD-J program is continued, and then the processing shown in this flowchart ends.

  If it is determined in step S102 that the BD-J program is not being executed, or if it is determined in step S103 that the BD-J program is being executed but is not a continuation program, the process proceeds to step S111. move on.

  In step S111 to step S113, the execution of the BD-J program is stopped, the content playback control using the medium other than the ejected BD41 as a source is started, and video and audio playback based on the medium other than the BD41 is performed. . More specifically, the playback control management unit 21 controls the playback of video and audio by the BD-J title playback control unit 22 by stopping the execution of the BD-J program by the BD-J title playback control unit 22. Stop (step S111). Further, the playback control management unit 21 controls the playback control unit excluding the BD-J title playback control unit 22 from a medium other than the BD, that is, an HDD in which a program for digital TV broadcasting, radio broadcasting, and navigation is recorded. The medium to be played and the playback control unit are determined (step S112), and the playback control unit associated with the determined medium is started to control playback (step S113).

  That is, the playback control management unit 21 includes any one of the playback control units excluding the BD-J title playback control unit 22, such as the digital TV playback control unit 26, the AM / FM playback control unit 27, and the navigation playback control unit 28. Specify and start playback control. When the reproduction control is started, at least one of a video signal and an audio signal generated based on any medium determined by the reproduction control management unit 21 is output to the touch panel display 2 and the speaker 3.

That is, in step S111 to step S113, the disc playback function is stopped as the disc is ejected, and playback based on another medium is started, which is the same as the mode switching processing conventionally performed in an in-vehicle device or the like. Processing is performed. For this reason, if the title being played on the ejected BD is not a BD-J title, or if the BD-J program being executed is not a program that is continuously executed, the user must eject the disc. Along with the operation, a conventional mode switching function can be provided. Thereafter, the processing shown in this flowchart ends.

  In step S112 described above, the reproduction control management unit 21 determines a medium to be reproduced (and a reproduction control unit to start control) in accordance with the ejection operation of the BD 41. The control unit may be determined as a medium and reproduction control unit that is started in accordance with the ejection operation, or a medium and reproduction control unit (so-called “reproduction control unit”) that was last reproduced before the reproduction of the ejected BD 41 is started. (Last mode) may be determined as a medium and a reproduction control unit started in accordance with the ejection operation.

  In the display area, a message, an icon, or the like for notifying the user of the content of the video or sound currently output to the display area or the medium may be displayed. For example, when a video or sound of a BD-J title controlled by a BD-J program that is continuously executed is output, “BD”, the digital TV playback control unit 26 that has started control in accordance with the ejection operation. When the video or sound is output by displaying “DTV” or the like, the user can grasp the change of the function mode switched as the disc is ejected, and the user can be prevented from being confused. .

  Next, the BD 41 is loaded into the multi-drive 4 in a state where the BD-J program is continuously executed after the removal of the BD 41, that is, in the state where the processing in step S104 is performed and the processing shown in FIG. An outline of the processing in the case of failure will be described.

  First, the loading / discharging detection unit 34 detects that a disk loading operation by the user has been performed on the multi-drive 4 or that a loading operation has been performed on the multi-drive 4 and a disk has been loaded. Then, the disc determination unit 33 reads information for identifying the disc from the BD 41 related to the loading detection, and compares this information with information indicating the continued disc indicated in the BD-J program being executed. Thus, it is determined whether or not the loaded BD 41 is a continuation disk of the BD 41 in which the ejection operation is detected in step S101 in FIG. If it is determined that the loaded disc is a continuous disc, such as when the identification information matches, the data read from the newly loaded BD is read by the BD-J program that is being continuously executed. The reproduction control of the used video and sound is started, and the video and sound related to the loaded BD are reproduced.

  On the other hand, when it is determined that the loaded disc is another disc that is not a continuous disc, reproduction of content based on the newly loaded BD 41 is started. The playback control management unit 21 causes the BD-J title playback control unit 22 or the HDMV title playback control unit 23 to start playback processing based on the loaded BD 41 in accordance with the title control method recorded on the loaded BD 41. If the title to be reproduced first on the loaded BD 41 is a BD-J title and the BD-J title reproduction control unit 22 cannot execute a plurality of BD-J programs, the execution is executed. Execution of the continued execution program that has been continued may be stopped.

In the playback control switching process described with reference to FIG. 4 above, the determination as to whether to switch playback control according to the same mode management method as before or whether to continue execution of the BD-J program without switching playback control is BD. -Determined based on the execution state of the J program and the type of the BD-J program. However, the details of the processing may be determined by further taking into account the contents set in advance for the content reproduction system 1 and the result of selection by the user. FIG. 5 is a flowchart showing the flow of a playback control switching process that accompanies the disc ejection, which can be executed instead of the process shown in FIG. 4 in the present embodiment. The process shown in this flowchart is started when a discharge operation of the BD 41 is performed during the reproduction of the content based on the BD 41 loaded in the multi-drive 4 as in the process shown in FIG. . In addition,
The processing order of the playback control switching processing according to the present invention can be changed as appropriate in accordance with the embodiment, and the processing order is not limited to the example shown below.

  In step S201 to step S203, a discharge operation of the BD 41 is detected, and it is determined whether or not the BD-J program to be continuously executed is being executed. The details of the processing shown from step S201 to step S203 are substantially the same as the processing from step S101 to step S103 described with reference to FIG. In step S202 and step S203, when it is determined that the BD-J program that is continuously executed when the ejection operation is detected, the process proceeds to step S204. If it is determined in step S202 that the BD-J program is not being executed, or if it is determined in step S203 that the BD-J program is being executed but is not a continuation program, the process proceeds to step S211.

  In step S204, the setting contents of the content reproduction system 1 are referred to. Here, in the HDD 13, when the BD 41 is ejected, setting contents indicating whether to continue execution of the continuation program or to switch to reproduction control by another reproduction control unit without continuing execution Is remembered. The reproduction control management unit 21 refers to the setting content acquired from the HDD 13 by the setting content acquisition unit 32 to determine whether or not to continue the execution of the continuation program. If the setting content acquired from the HDD 13 is the setting content indicating continuous execution of the continuation program, the process proceeds to step S205. If the setting content acquired from the HDD 13 is the setting content indicating that execution is to be stopped even if it is a continuation program, the process proceeds to step S211.

  By doing in this way, according to the content reproduction system 1 according to the present embodiment, even when a BD-J program intended to be continuously executed during the ejection operation of the BD 41 is being executed, the setting contents are stored in the HDD 13 in advance. By saving, the BD-J program can be stopped and the playback control can be switched. For example, a user who does not want to continue playback of the content related to the BD 41 after discharging the BD 41 stores the setting content indicating that the execution of the continuous program is not continued in the HDD 13, so that the content playback system 1, when the operation of discharging the BD 41 is performed, the mode switching process as desired by the user can be performed.

  In step S205, the execution of the BD-J program that has been executed before the discharging operation of the BD 41 is continued. Details of the process shown in step S205 are substantially the same as the process of step S104 described with reference to FIG. Thereafter, the processing shown in this flowchart ends.

  In step S211 to step S213, execution of the BD-J program is stopped, content playback control using a medium other than the ejected BD41 as a source is started, and video and audio playback based on the medium other than the BD41 is performed. . Details of the processing shown in steps S211 to S213 are substantially the same as the processing of steps S111 to S113 described with reference to FIG. That is, from step S211 to step S213, the disc playback function is stopped as the disc is ejected, and playback based on another medium is started, which is the same as the mode switching processing that has been conventionally performed in an in-vehicle device or the like. Processing is performed. Thereafter, the processing shown in this flowchart ends.

FIG. 6 is a flowchart showing the flow of a playback control switching process that accompanies disc ejection, which can be executed instead of the process shown in FIG. 4 in the present embodiment. The process shown in this flowchart is started when a discharge operation of the BD 41 is performed during the reproduction of the content based on the BD 41 loaded in the multi-drive 4 as in the process shown in FIG. . Note that the processing order of the playback control switching processing according to the present invention can be changed as appropriate in accordance with the embodiment, and the processing order is not limited to the examples shown below.

  In step S301 to step S303, a discharge operation of the BD 41 is detected, and it is determined whether the BD-J program to be continuously executed is being executed. Details of the processing shown in steps S301 to S303 are substantially the same as the processing of steps S101 to S103 described with reference to FIG. In step S302 and step S303, when it is determined that the continuation program is being executed when the discharge operation is detected, the process proceeds to step S304. If it is determined in step S302 that the BD-J program is not being executed, or if it is determined in step S303 that the BD-J program is being executed but is not a continuation program, the process proceeds to step S311.

  In step S304, a screen for allowing the user to select whether to continue the continuation program actually or stop the continuation program is displayed. The video output unit 35 causes the touch panel display 2 to display a continuation / stop selection screen. In other words, when the process according to this flowchart is executed, when the user performs a discharge operation of the BD 41 via the buttons provided on the touch panel display 2 or the content reproduction system 1, the “application” is displayed on the touch panel display. Options such as buttons that can be selected by the user are displayed with messages such as “Continue execution” and “Stop running application”. Here, the touch panel display 2 displays a video (for example, a message display screen such as “Please insert disc 2”, a game screen, a menu screen, etc.) under the control of the BD-J program that is continuously executed. Therefore, the above-described option display is displayed so as to be overlaid (overlaid) on the video controlled by the BD-J program.

  In step S305 and step S306, it is determined whether or not the continuous program is to be continuously executed according to the selection input by the user. The user looks at the option display displayed in step S304 and determines whether to continue the continuation program or to stop the continuation program. The input reception unit 37 sets the touch panel display 2 or the content reproduction system 1 to A selection input by the user is received via the provided buttons (step S305). Then, the playback control management unit 21 determines whether the user's selection received by the input receiving unit 37 is to continue or stop the execution of the continuation program (step S306). If it is determined that the user's selection is to continue execution of the program, the process proceeds to step S307. If it is determined that the user's selection is to stop execution of the program, the process proceeds to step S311.

  By doing in this way, according to the content reproduction system 1 according to the present embodiment, even when a BD-J program intended to be continuously executed during the discharging operation of the BD 41 is being executed, the user is notified each time the discharging operation is performed. It is possible to make an inquiry and perform mode switching processing according to the user's wishes. For example, according to the present embodiment, when a discharge operation of a BD 41 with a continuous disk is performed, whether the discharge operation is a discharge operation performed for the purpose of replacement with a continuous disk, It is possible to determine whether or not the discharge operation is performed for the purpose of switching to viewing or the like of the content related to the medium, and to provide management of reproduction control in accordance with the user's intention.

  In step S307, the execution of the BD-J program that has been executed before the discharging operation of the BD 41 is continued. Details of the process shown in step S307 are substantially the same as the process of step S104 described with reference to FIG. Thereafter, the processing shown in this flowchart ends.

  In steps S311 to S313, execution of the BD-J program is stopped, content playback control using a medium other than the ejected BD41 as a source is started, and video and audio playback based on the medium other than the BD41 is performed. . Details of the processing shown in steps S311 to S313 are substantially the same as the processing of steps S111 to S113 described with reference to FIG. Thereafter, the processing shown in this flowchart ends.

  According to the present embodiment, in the content playback system 1 in which video and audio playback is controlled using the BD-J program read from the BD 41, even when the BD 41 is ejected during execution of the BD-J program. In addition, while providing the same function as the mode management in the conventional playback device, it is possible to provide a behavior according to the intention of the creator of the content recorded on the BD 41 when necessary.
