Hereinafter, an example of a preferred embodiment for realizing the present invention will be described with reference to the drawings.
FIG. 1 shows a conceptual module configuration diagram of a configuration example of the present embodiment.
The module generally refers to a component such as software or hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a program but also a module in a hardware configuration. Therefore, the present embodiment also serves as an explanation of a program, a system, and a method. However, for the sake of explanation, the words “store”, “store”, and equivalent terms are used. However, when the embodiment is a program, these terms are controlled to be stored in the storage device. I mean. In addition, the modules correspond almost one-to-one with the functions. However, in mounting, one module may be composed of one program, or a plurality of modules may be composed of one program. A plurality of programs may be used. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. In the following, “connection” includes not only physical connection but also logical connection (data exchange, instruction, reference relationship between data, etc.).
Further, the system or apparatus includes a configuration in which a plurality of computers, hardware, devices, and the like are connected via a network and the like, and includes a case where the system or device is realized by a single computer, hardware, devices, and the like. The term “predetermined” is used in addition to a predetermined meaning, including the meaning according to the situation / state at that time or the situation / state until then.
Hereinafter, a mobile phone will be mainly described as an information processing apparatus, an image file will be displayed on a display as a file reproduction, and an application program (hereinafter also simply referred to as an application) will be mainly described as a program.

  The information processing apparatus according to the present embodiment can reproduce a file. As shown in FIG. 1, an application 102, a file 101, an application execution environment module 110, an application state control module 120, an application A state management module 130 and a file reproduction module 140 are provided.

  The application 102A reproduces the file 101A. Similarly, the application 102B reproduces the file 101B. For example, when the application 102B (first program) tries to display the file 101B on the display of the information processing apparatus, the application 102A (second program) already displays the file 101A. At this time, the heap memory in the information processing apparatus is mostly occupied by the application 102A, and the application 102B cannot secure a heap memory that can display the file 101B as it is. The present embodiment guarantees reproduction of the file 101B by the application 102B even in such a situation. The application 102 includes, for example, a browser, and also includes a browser plug-in (which has a function as a browser subprogram and extends the function of the browser. For example, a file is reproduced. ) Is also included.

  The application execution environment module 110 is connected to the application 102A, the application 102B, the application state control module 120, and the application state management module 130, and includes an instruction reception module 111 and an environment control module 112. This is an execution environment for a plurality of applications 102, receives a playback instruction for the file 101 from the application 102, and causes the file playback module 140 to perform playback via the application state control module 120 and the application state management module 130. is there.

  The instruction receiving module 111 receives an instruction to reproduce the file 101 by the application 102. For example, after receiving an instruction to reproduce the file 101A from the application 102A, an instruction to reproduce the file 101B from the application 102B may be received.

The environment control module 112 controls the execution of each application 102. Specifically, control for executing the reproduction instruction received by the instruction receiving module 111 is performed. For example, the playback instruction is passed to the application state control module 120, the state of each application 102 is passed to the application state management module 130, and the file playback module 140 and the like are controlled. Further, the environment control module 112 determines whether the information processing apparatus has an environment necessary for generating the reproduction instruction file 101 received by the instruction receiving module 111. For example, the capacity of the heap memory that can be used at present is detected, and it is determined whether the capacity necessary for generating the reproduction instruction file 101 is satisfied. Further, when the reproduction instruction includes an audio output, it is detected that the audio output is not disabled.
Note that the environment control module 112 may control the information processing apparatus so that only one application 102 is activated.

  The application state control module 120 is connected to the application execution environment module 110, the application state management module 130, and the file playback module 140, and includes an application state detection module 121, an application end control module 122, and an application start control module 123. Yes.

The application state detection module 121 detects the processing state of the application 102A that has already played back a file when the instruction receiving module 111 receives a playback instruction for the application 102B. In detecting the processing state, the application state management module 130 is queried to obtain the result.
The application state detection module 121 may detect the processing state of the application 102 when there is an application 102 that is reproducing the file 101 having a predetermined capacity or more. That is, the processing state of the application 102 to be terminated is detected after the effective application 102 for reproducing by the application 102B is specified. For example, the predetermined capacity includes a memory capacity necessary for reproduction by the application 102B.
The application state detection module 121 may perform the above-described detection when the environment control module 112 determines that the information processing apparatus has an environment necessary for reproducing the file 101. Good.

  When the application 102 is a browser and there is a plug-in as a program for playing the file 101 in the browser (that is, the application 102 includes a browser and its plug-in), the instruction receiving module 111 If a plug-in (application 102A) that is playing back a file is received when the playback instruction is received, the processing state of the browser (application 102A) corresponding to the plug-in is detected.

The application end control module 122 controls to end the application 102A that is playing back the file in the information processing apparatus when the instruction receiving module 111 receives the playback instruction of the application 102B.
Further, the application end control module 122 may control the application 102A to end when the application state detection module 121 detects that the application 102A is in a suspended state.
The application end control module 122 may control the application 102A to end when the application state detection module 121 detects that the application 102A is playing a file having a predetermined capacity or more.

  Also, when the application 102 is a browser and there is a plug-in as a program for playing the file 101 in the browser, the application state detection module 121 detects that the browser (application 102A) is in a suspended state Terminates the browser plug-in (application 102A). In other words, the state detection target is a browser, and the end target is a plug-in.

The application activation control module 123 performs control so that the application 102 is activated. Further, the application 102 that has been terminated by the application termination control module 122 may be controlled to be activated.
In addition, when the application 102 is a browser and there is a plug-in as a program for playing the file 101 in the browser, the application is terminated when the browser (application 102A) returns from the suspended state during startup (resume). Control is performed to activate the plug-in (application 102A) terminated by the control module 122. That is, once the environment such as heap memory is used for playback by the application 102B, but when the application 102A is restored, the application 102B is suspended, so the plug-in that is the application 102B is terminated, and the application 102A Control to restart a certain plug-in.

  The application state management module 130 is connected to the application execution environment module 110, the application state control module 120, and the file playback module 140. The current state of each application 102 is managed. That is, the status of each application 102 is obtained from the environment control module 112 and the status of each application 102 is returned in response to an inquiry from the application status control module 120. The state of the application 102 includes starting, interruption (suspend), and termination.

The file playback module 140 is connected to the application state control module 120 and the application state management module 130. After the application 102A is terminated by the termination control by the application termination control module 122, the file 101B is reproduced by the application 102B received by the instruction receiving module 111.
Further, when the application 102 is a browser and there is a plug-in as a program for playing the file 101 in the browser, the plug-in (application 102A) is terminated after termination by the termination control by the application termination control module 122. The file 101B is reproduced by the plug-in of the application 102B received by the receiving module 111.

FIG. 2 is a diagram showing an example of a module configuration when the present embodiment is further embodied.

The application execution environment module 110, the application state control module 120, and the application state management module 130 shown in the example of FIG. 1 are included, and redundant description thereof will be omitted. In contrast to the other module configuration examples, the file 210 reproduced by the application corresponds to the file 101A and the file 101B, the application group 220 corresponds to the application 102A and the application 102B, and the file reproduction library 250 corresponds to the file reproduction module 140. Applicable.

The file 210 reproduced by the application is stored in a memory in the information processing apparatus or downloaded from a server or the like connected to the information processing apparatus through a communication line and reproduced by the application group 220.
The application group 220 includes a plurality of applications 102, and issues a reproduction instruction to the application execution environment module 110 in order to reproduce the file 210 reproduced by the application.
The file reproduction library 250 is a library of an image display program, a sound output program, a moving image output program, and the like.
The platform 260 is hardware (display or the like) or software (OS or the like) serving as a base of the information processing apparatus, and performs a reproduction process such as final display according to an instruction from the file reproduction library 250.

  The information processing apparatus in which this embodiment is implemented may be a mobile phone 300 as shown in FIG. The mobile phone 300 is, for example, a character input device for inputting characters in response to a request such as a telephone number or an application program, a microphone 305 that can input voice so as to have a function as a telephone, a speaker 304 that can output voice. A key 302, an antenna 303 for transmitting and receiving radio waves for data communication, a display 301 for displaying an image file by an application program as a result of character input by the key 302, and the like. The mobile phone 300 includes a CPU that executes an application program, a memory, a SIM (Subscriber Identity Module), hardware such as a communication circuit, and the like, and is a computer that is software for realizing an information processing apparatus. A program is stored in a memory, and software and hardware resources cooperate to implement an information processing apparatus.

FIG. 4 is an explanatory diagram showing a display example of the display 400 (301) in the mobile phone 300.
In the display 400 shown in the example of FIG. 4A, an icon 410, a file playback area 420, an icon 430, an icon 440, and a cursor 450 are displayed. In the file reproduction area 420, for example, an image such as a photograph is displayed. In this state, the application 102 corresponding to the file reproduction area 420 is in an active state, but the application 102 corresponding to the icon 410, the icon 430, and the icon 440 is in an interrupted state. Here, it is assumed that the cursor 450 is moved to the icon 430 and the application 102 corresponding to the icon 430 is returned (resume) according to the user's operation.

  FIG. 4B is a display example when the application 102 corresponding to the icon 430 is activated. That is, the file playback area 431 is displayed by the application 102 corresponding to the icon 430. For example, an image of a document such as a PDF (Portable Document Format) is displayed in the file playback area 431. At this point, the file playback area 420 is suspended, the heap memory occupied to display the image is released, and the application 102 corresponding to the icon 430 newly uses the heap memory.

FIG. 5 is a flowchart showing an example of processing according to the present embodiment.
In step S <b> 502, the instruction receiving module 111 receives a file playback instruction from the application 102.
In step S504, the environment control module 112 determines whether the information processing apparatus has an environment necessary for generating the file 101 that is the target of the reproduction instruction. If so, the process proceeds to step S506. Otherwise, the process proceeds to step S514.

In step S506, the application state detection module 121 determines whether another playback application has already played back the file. If it is being played, the process proceeds to step S508; otherwise, the process proceeds to step S512.
The application state detection module 121 makes an inquiry by making an inquiry to the application state management module 130. The application state management module 130 stores, for example, the application state management table 600 shown in the example of FIG. Use this to answer the query. FIG. 6 is an explanatory diagram showing an example of the data structure of the application state management table 600. The application status management table 600 has an application column 610 and a status column 620. The application column 610 stores an identifier (which may be a name or the like) that uniquely identifies the application. The status column 620 stores the status of the application. The example shown in FIG. 6A shows that the application A is in a suspended (suspended) state, a file reproduction instruction is issued from the application B, and the application B is in a running state. The application state detection module 121 determines from the state shown in the example of FIG. 6A that another playback application has already played a file.
If the application state detection module 121 is playing back a file having a predetermined capacity or more in place of or in addition to the above-described processing, step S506 is changed to the processing state of the application. You may make it detect. If there is an application that is playing a file larger than the predetermined capacity, the process proceeds to step S508, and otherwise, the process proceeds to step S512.

  In step S508, the application end control module 122 ends the other reproduction application (interrupted application) determined in step S506. As a result, the heap memory occupied by other playback applications is released. The application end control module 122 notifies this to the application state management module 130, and the application state management module 130 manages the state. That is, the application state management table 600 shown in the example of FIG. 6A is changed to the application state management table 600 shown in the example of FIG. 6B. Specifically, the application A is changed from the suspended (suspended) state to the finished state.

In step S510, the environment control module 112 sets the application that has received the reproduction instruction received in step S502 to a file reproducible state. Specifically, since the heap memory occupied by the application terminated in step S508 has been released, this heap memory is allocated to the application that has issued the reproduction instruction.
In step S512, the file reproduction module 140 reproduces the file.
In step S514, the environment control module 112 discards the file reproduction instruction and notifies the application 102 that has issued the file reproduction instruction to that effect. The application 102 performs error processing (displaying that reproduction is not possible).
Note that when the reproduction application terminated in step S508 returns (resumes), the processing of the flowchart shown in the example of FIG. 5 is performed. In other words, a reproduction instruction is issued from the reproduction application upon returning. On the other hand, the playback application that was being executed before the return is suspended and terminated.

Next, as a more specific example, a case where a plurality of browsers play files with plug-ins will be described. A browser is an example of an execution platform.
The information processing apparatus can start a plurality of browsers. However, only one browser can be in an executable state, in which case other browsers are suspended. Then, when the file is played back, the browser activates a plug-in suitable for the file.
Here, the browser C and the browser D are activated, and the browser C is already in a state where the plug-in in the browser C is reproducing the file. In this state, the browser D tries to reproduce the file using the plug-in. Since the file is being played back by the plug-in of browser D, browser C is in a suspended state.
This state is managed by the application state management module 130 using the application state management table 700 shown in the example of FIG. FIG. 7 is an explanatory diagram showing an example of the data structure of the application state management table 700. The application state management table 700 has an application column 710 and a state column 720. Further, the application column 710 has an execution platform column 711 and a plug-in column 712. The execution platform column 711 stores an identifier (which may be a name or the like) that uniquely identifies the execution platform. The plug-in column 712 stores an identifier (which may be a name or the like) that uniquely identifies the plug-in. The status column 720 stores the status of the execution platform or plug-in. The application state management table 700 shown in the example of FIG. 7A shows this state. That is, the browser C and the plug-in C1 of the browser C are suspended (suspended), and the browser D and the plug-in D1 of the browser D are active.

  Since the plug-in C1 of the browser C is in a suspended (suspended) state, the application end control module 122 ends the plug-in C1. The application state management table 700 shown in the example of FIG. 7B shows this state. That is, the browser C is in an interrupted (suspended) state, the plug-in C1 of the browser C is in an end state, and the browser D and the plug-in D1 of the browser D are in an active state.

Next, a case where the browser C is changed from the interrupted state to being activated (resume) will be described. At this time, the browser C and the plug-in C1 of the browser C are in an active state, and the browser D and the plug-in D1 of the browser D are suspended. Then, the plug-in C1 of the browser C issues a file reproduction instruction. Here, the plug-in D1 of the browser D in the suspended state is terminated.
As described above, by limiting the number of plug-ins for reproducing files to one in the information processing apparatus, execution of file reproduction using a large amount of heap memory is ensured.

  Note that the hardware configuration of the computer on which the program according to the present embodiment is executed is a general computer as shown in FIG. 8, specifically a computer that is built in the mobile phone 300. .

An information processing device that does not have sufficient memory capacity or the like for reproducing a plurality of files is an object, and is particularly suitable for a portable information processing device.
Further, although the display of the image file on the display is exemplified as the file reproduction, the output may be an output of an audio file through a speaker, an output of a moving image file to a display, or the like. The first program and the second program may be the same type of program, but may be different types of programs. For example, the first program may display an image file and the second program may output a moving image file.
Moreover, although the case where the number of programs for reproducing a file is two is illustrated, it may be three or more.

Note that the described program can be stored in a recording medium, and in that case, it can be understood as an invention of a “computer-readable recording medium on which a program is recorded”.
The “computer-readable recording medium on which a program is recorded” refers to a computer-readable recording medium on which a program is recorded, which is used for program installation, execution, program distribution, and the like.
The recording medium is, for example, a digital versatile disc (DVD), which is a standard established by the DVD Forum, such as “DVD-R, DVD-RW, DVD-RAM,” and DVD + RW. Standard “DVD + R, DVD + RW, etc.”, compact disc (CD), read-only memory (CD-ROM), CD recordable (CD-R), CD rewritable (CD-RW), Blu-ray disc ( Blu-ray Disc (registered trademark), magneto-optical disk (MO), flexible disk (FD), magnetic tape, hard disk, read-only memory (ROM), electrically erasable and rewritable read-only memory (EEPROM), flash Includes memory, random access memory (RAM), etc. .
The program or a part of the program can be recorded on the recording medium and stored or distributed. Also, by communication, for example, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a wired network used for the Internet, an intranet, an extranet, etc., or wireless communication It can be transmitted using a transmission medium such as a network or a combination thereof, and can also be carried on a carrier wave.
Furthermore, the program may be a part of another program, or may be recorded on a recording medium together with a separate program.
