JP 2002-1000016 A

  By the way, there are a huge number of combinations of application programs and devices to be developed. In an application execution environment independent of hardware and OS, such as Java (registered trademark), for example, it is mounted on the execution environment of Java (registered trademark) installed in the device of company A and the device of company B Usually, the implementation method differs depending on the execution environment of Java (registered trademark). Under these conditions, even if the same Java (registered trademark) application is operated, a difference in behavior occurs depending on the device. The processing speed for executing the application and the response speed when the user performs input differ depending on the device.

  The manufacturer can guarantee the operation to some extent, but the application program created by one individual's hobby can be guaranteed only by the player owned by the individual. Depending on the application program, it may not work on a specific device or a problem may occur. If the problem is a simple problem, it is still good, but in some cases, execution of the application program may lead to failure of the device that executed the application program.

  In view of the above problems, an object of the present invention is to provide a playback apparatus that can suppress problems caused by application programs.

  In order to solve the above problems, a playback device according to the present invention is a playback device that acquires and executes an application program, and shows an operation record when the application program is operated in a device of the same type as the own device. It is characterized by comprising operation result information acquiring means for acquiring information and processing means for performing processing relating to the application program based on the operation result information.

  Here, the playback device is one of the mass-produced products, and the same type of equipment as the own equipment refers to equipment other than the mass-produced own equipment, and equipment produced in the same process as the own equipment and having the same specifications. Say. In addition, the processing performed by the processing means referred to here is executed on the own machine when it is determined that the application program can be executed, or installed on the own machine when it is determined that the application program can be installed. In the case where it is determined that the application program may be acquired, the application program may be acquired, or the contents of the operation result information may be presented to the user.

With the above configuration, the application program to be acquired by the user is operated based on the operation results when the application program is operated on the same type device other than the own device before the application program is operated on the playback device. It becomes possible to determine the response to.
In addition, when the application program is executed on a device of the same type as the own device, the operation result information is information on the frequency of occurrence of a failure in the device of the same type as the own device, or the occurrence of a defect in the device of the same type as the own device. Information on the number of incidents or information on the status of defects occurring in the same type of device as the own device, and the processing means changes the contents of the processing in accordance with the frequency of occurrence of the defects or the number of occurrences of defects. That's good.

As a result, the playback apparatus can perform application processing, for example, whether to execute the application, using the occurrence frequency of defects including the failure frequency as a criterion.
In addition, the playback device further corresponds to a plurality of different application programs, and stores operation result information storage means for storing in advance each operation result information when each is operated in the same type of device as the own device, Application information acquisition means for acquiring information related to the application program that is going to be executed in the machine, and the operation result information acquisition means receives operation result information corresponding to the information related to the application program from the operation result information storage means. It is good also as acquiring by reading.

As a result, the playback apparatus can acquire the operation result information from the memory inside the own apparatus and refer to it. When the own device has a sufficient memory capacity, the own device stores the operation result information, and almost all processing can be performed only by the own device.
The playback apparatus further includes a communication unit that communicates with an external device, and includes an application information acquisition unit that acquires information about an application program, and a host device information storage unit that stores information about the host device, The operation result information acquisition means corresponds to the operation result information corresponding to the information related to the application program and the information related to the own device through the communication means, corresponding to a plurality of different application programs, and the same type as the own device. It is good also as acquiring each operation | movement performance information at the time of making it operate | move in this apparatus from the external apparatus which has memorize | stored beforehand.

  As a result, when the player does not store the operation result information, the playback device corresponds to the operation result information based on the information such as the name of the application and the information such as the model number for specifying the own device. Can be acquired from an external server storing the password. Storing all the application programs and the operation result information of the own device entails enormous amounts of information and places a burden on the memory of the own device. By adopting this configuration, the load on the memory of the own device can be reduced, and the amount can be used for holding the moving image content.

  Further, the operation result information is information indicating the frequency of occurrence or the number of occurrences of defects occurring in a device of the same type as the own device when the application program is operated in the same type of device as the own device. Further includes reference information storage means for preliminarily storing reference information indicating whether or not the application program may be executed, installed, or acquired, according to the occurrence frequency or the number of occurrences of the defect, Processing related to the application may be performed based on the operation result information and the reference information.

As a result, the playback device can determine whether the application program can be operated on its own device in comparison with the operation result information acquired based on the determination criterion information.
In addition, the playback device further includes an application acquisition unit that acquires an application program, and the reference information indicates a criterion for determining whether or not the application program may be executed according to the occurrence frequency or the number of occurrences of the defect. The processing means executes the application program acquired by the application acquisition means by itself when it is determined that the application program may be executed based on the operation result information and the reference information. Good.

As a result, the playback apparatus can execute the application when it is determined that the application program may be executed on its own device.
The playback apparatus further includes an application acquisition unit that acquires an application program, and the reference information indicates a criterion for determining whether or not the application program may be installed according to the occurrence frequency or the number of occurrences of the defect. The processing means installs the application program acquired by the application acquisition means on its own machine when it is determined that the application program may be installed based on the operation result information and the reference information. It may be allowed.

  As a result, the playback apparatus can install the application when it is determined that the application program is operable on the own apparatus. The application program to be acquired can be an application program that can be executed immediately on its data format, or an application program that can be executed only after it is installed on its own device, and can deal with an application program that needs to be installed.

  In addition, the playback device further includes an application acquisition unit that acquires an application program, and the reference information indicates a criterion for determining whether or not the application program may be acquired according to the occurrence frequency or the number of occurrences of the defect. The processing means may acquire the application program when it is determined that the application acquisition means may acquire the application that the application acquisition means is to acquire based on the reference information.

As a result, it is possible to determine whether the application program to be acquired on the own machine can be operated on the own machine at a stage where the application program has not yet been acquired. When an application program is acquired via the network, effects such as reduction in communication costs can be obtained.
The playback apparatus may further include display means for displaying the contents of the operation result information acquired by the operation result information acquisition means.

Thereby, the playback device can present the contents of the acquired operation result information to the user, and can ask the user whether to execute the application program on the own device. In addition, in the operation result information, it is conceivable that information such as a situation in which a failure occurs is described in the remarks column, and this can be used as a judgment material.
An application program processing method in a playback device capable of acquiring and executing an application program, the acquisition step of acquiring information related to the application program, and the playback device based on the information related to the application program Operation result information acquisition step for acquiring operation result information indicating an operation result when the application program is operated in the same type of device, and processing of the application program based on the operation result information acquired in the operation result information acquisition step And a processing step for performing.

The video plane 272 is a plane for storing uncompressed pictures. A plane is a memory area for storing pixel data for one screen in the playback apparatus. The resolution in the video plane 272 is 1920 × 1080 (pixels), and the picture data stored in the video plane 272 is composed of pixel data expressed by 16-bit YUV values. In the video plane 5, the playback video for each frame in the video stream can be scaled. Scaling is to change the reproduced image for each frame to either 1/4 (referred to as a quota) or 1/1 (referred to as a full scale) of the entire video plane 5. Since such scaling is executed in accordance with an instruction from the CPU 205, it is possible to produce a screen effect in which the playback image of the video stream is driven to the corner of the screen or is displayed entirely.

The user processing unit 290 receives an instruction from the user via a remote controller and outputs the content to the CPU 205.
<Data>
Here, data used for determining whether the BD player 100 executes or installs an application program will be described.

First, the operation result information indicating the compatibility between the same type machine of the BD player 100 and the application program will be described.
The data and operation result information held by the operation result holding server 120 are shown in the operation result information 300 shown in FIG. The operation result information 300 includes an application program name 301 and a device name 302, adaptation 303, and operation failure 304 corresponding to the application program name 301.

  The application program name 301 means the name of the application program, and the device name 302 describes the name of the DVD or BD device. The adaptation 203 indicates whether or not the application program can actually be executed or installed on the device. If possible, the frequency of the malfunction is indicated in the malfunction 304. There are cases where the adaptation 304 is “possible” and “impossible”, and the malfunctioning 304 has five stages of “none”, “rare”, “small”, “medium”, and “many”. It shows that it becomes. This stage is based on the malfunction report of the same model and application program received from the user, for example, “None” if the number of failures is 0, “Rare” if 1-5, and “Low” if 5-10. “10” to “30” is defined as “medium”, and more than that is defined as “many”. This setting may differ depending on each application program and each device. The information on the malfunction 304 is sequentially updated by the administrator of the operation result holding server 120. If adaptation is not possible, the application program does not run on the device, so “−” is written in the malfunction column.

In the operation record information 300, for example, in the case of “application program Aver1.00”, the operation record with the device “DVD B” is “adaptive: possible, poor operation: small”.
Next, data indicating a criterion for determining whether or not the BD player 100 may execute or install an application program will be described with reference to the criterion information 233 in FIG.

  The BD player 100 stores the reference information 233 in the built-in ROM 230, and as shown in FIG. 4, an operation failure state 401 is shown corresponding to the adaptation state 400. An execution or installation permission / inhibition 402 is shown. When applicable, it is determined by each malfunction stage. If adaptation is not possible, of course, neither execution nor installation is possible.

Next, information held by the application program and transmitted from the BD player 100 to the operation result holding server 120 will be described.
In addition to the application program main body, the application program includes information such as the application program name, version information, data size, file type, and the like in its header portion. The application program name and version information are extracted and a BD player is extracted. 100 transmits to the operation result holding server 120. With this information, the BD player 100 and the operation result holding server 120 can identify the application program.

The BD player 100 stores data on its own device in the ROM 230 (not shown), for example, information such as the type of equipment, which manufacturer has developed, and what is the model number set by the manufacturer. Information is also transmitted to the operation result holding server 120. This information is set by the manufacturer when the BD player 100 is shipped. With this information, the operation record holding server 120 can identify the BD player 100 and search the operation record information 300 by combining it with the application program information.
<Operation>
Next, the operation timing of the BD player and its peripheral devices according to the present embodiment will be described using the timing chart shown in FIG.

  First, the BD player 100 that has received an application program acquisition request from the user's remote controller operation or the like by the user processing unit 290 issues an application program acquisition request to the application server 110 (step S501). Upon receiving the application program acquisition request from the BD player 100, the application server 110 returns the requested application program or its compressed archive to the BD player 100 (step S502).

  The BD player 100 that has acquired the application program transmits information such as the model number of the own device and information such as the name of the acquired application program to the operation result holding server (step S503). The operation record holding server 120 that has received the BD player information and the application program information searches the operation record information 300 matching the two pieces of information, and returns the operation record information corresponding to the acquired information to the BD player 100 ( Step S504). The BD player that has acquired the operation result information determines whether or not to execute or install the application program according to the reference information 233 stored in the device itself (step S505), and executes or installs the subsequent application program. If possible, execute or install an application program.

Next, the operation of the BD player 100 according to the present embodiment will be described using the flowchart shown in FIG. 6 and the functional block diagram of FIG.
First, the user processing unit receives an instruction from the user, and in order to acquire an application program, the Network Device 201 establishes a connection with the application server 110 and acquires the application program (step S601). The application program is held in the local memory 210 via the local storage 202. The name and version information of the application program are extracted from the header portion of the held application program, and information indicating the name and model number of the own device is read out from the ROM 230 together with the information to the operation result holding server 120 via the Network Device 201. To send. In response to the transmission, operation result information that is a reply from the operation result information holding server 120 is received (step S605). The operation result information is information obtained by the operation result holding server 120 extracting only the part corresponding to the BD player 100 and the application program acquired by the BD player 100 from the operation result information 300.

  Then, the reference information 233 is read from the ROM 230 (step S607), and is compared with the reference information 233 based on information on whether or not the acquired operation performance information can be applied and the frequency of occurrence of operation failure when it is possible. In addition, it is determined whether or not the application program may be executed or installed (step S609). First, when the adaptation is “impossible”, it is determined that the application program cannot be executed by itself and cannot be executed or installed. Next, when the adaptation is “permitted”, it is determined that the execution or installation can be performed when the information of the malfunction 304 is seen and when “not present”, “rare”, and “small”. Otherwise, it is determined that it cannot be executed or installed. For example, it is assumed that the own device is BD B and the acquired application program is version 1.44 of application A. In this case, since the operation result information to be acquired is “adaptive: acceptable, operation failure: low”, the CPU 205 determines that the application program may be executed in comparison with the reference information 233.

  When it is determined that the application program can be installed or executed, the application program is activated and reproduction of an image or the like by the application program is started (step S611). If it is determined that installation or execution of the application program is impossible, the application program is deleted from the own device (step S613). The above is the operation when the BD player 100 acquires the application program.

Finally, the flow when executing an application program will be briefly described with reference to the functional block diagram of FIG. Here, it is assumed that the application program is an application program that uses a partial scene in a certain moving image content A, for example, displays subtitles.
First, the BD player 100 that has received an application program activation instruction from the user by the user processing unit 290 reads the application program from the local memory.

  In addition to the GUI or graphics presented to the user, the application program holds a playlist that indicates which part of the moving image content A used for the application program is used at which timing, and the moving image content A shown in the playlist Is extracted and displayed at the timing indicated by the application program. The moving image content A is stored in the BD-ROM and read from the BD drive 204. The moving image content A may be stored in the ROM 230 and read out.

The moving image content A to be used is sequentially stored in the video plane 272 according to the play list, while the GUI and character data provided by the application program are sequentially stored in the I-Graphics plane 270. The images synthesized by the synthesis units 282 and 283 are displayed on a monitor connected to the BD player 100.
As application programs, in addition to subtitles, visual novel games that use partial scenes of video content, and programs that perform license management of video content and decide whether to allow or disallow playback of video content are assumed. The
<Supplement>
Although the BD player 100, which is the playback apparatus of the present invention, has been described according to the above embodiment, the present invention is not limited to this. Hereinafter, the modified example will be described.

(1) In the above embodiment, the playback device is a BD player. However, any player that can acquire and execute an application program may be used, for example, a DVD player that can execute an application program. Good.
(2) In the above embodiment, the operation result information is obtained from the operation result holding server 120. However, if the BD player has a sufficient storage capacity, the operation result information may be held by the BD player. This saves the trouble of communicating with the operation result holding server 120 and eliminates the need for communication costs.

  (3) In the above-described embodiment, the operation result information 300 describes whether the adaptation is possible according to the application program and the device, and only the occurrence frequency of the operation failure, but is described in the operation result information 300. However, the contents are not limited to this. Anything may be used as long as it is related to malfunction, and for example, a remarks column indicating details of a situation in which a malfunction occurs may be provided. The contents written in the remarks column may be presented to the user to allow the user to determine whether to execute the application program.

  (4) In the above embodiment, the application program is acquired, and information such as the name and version of the application program is extracted from the application program and transmitted to the operation record holding server 120. Alternatively, only the information of the application program may be acquired from the application server 110, and it may be checked whether the operation is possible before acquiring the application program main body. In this case, if a serious problem occurs, before acquiring the application program main body, the acquisition may be canceled or a GUI may be displayed to the user to make a suggestion to cancel. As a result, when the application program is acquired via the network, the application program is not downloaded unnecessarily, and communication costs are not generated.

  (5) In the above embodiment, the BD player itself determines whether or not it can be executed or installed. However, the BD player acquires the operation result information, and the contents are connected to the monitor connected to the BD player. Or the like, and may allow the user to determine whether to execute the application program. In this case, the user is allowed to make a selection using the remote controller attached to the BD player, and the user processing unit receives the signal and processes the application program according to the instruction content. Further, when detailed failure details are described in the operation result information, it can be used to determine whether to execute the application with reference to the details.

(6) In the above embodiment, there is one operation result holding server, but there may be a plurality of servers. For example, the operation performance information may be managed for each manufacturer. In this case, the playback device stores the address of the operation result holding server of the manufacturer that manufactured the device, and acquires the operation result information therefrom.
(7) In the above embodiment, the determination criterion is set in advance, but this setting may be changed by the user using a remote controller or the like. As a result, the application program can be executed with the user's favorite malfunction.

  (8) In the above embodiment, the operation result information 233 is that the operation result holding server 120 is updated by the administrator. However, the operation result information 233 collects the operation failure information, counts the number of operation failures, and automatically Specifically, the operation result holding server 120 may update the operation result information 233. In this case, the operation result holding server needs to store information for determining “rare”, “small”, “medium”, and “many” in accordance with the number of malfunctions that have risen.

  (9) In the above embodiment, the playback apparatus determines whether or not the operation is possible at the stage of acquiring the application program, but only the information specifying the application program to be acquired, such as the application program name, is obtained. May be acquired and transmitted to the operation record holding server, and if it is determined that the operation cannot be performed, acquisition of the application program main body may be suppressed, or the user may be displayed with a GUI or the like to call attention. This is considered to be effective in terms of both time and communication cost when the download time is required when the capacity of the application program main body is large.

  (10) In the above embodiment, the operation failure information column of the operation result information has five levels of “none”, “rare”, “small”, “medium”, and “many”. It may be the number of occurrences or a percentage of the number of failures that occurred with respect to the number of units shipped. In this case, the reference information also needs to have information that execution or installation is possible if the number of failure occurrences is less than or equal to. In the case of a percentage, it is necessary to have threshold information on whether execution or installation is possible.

(11) In the above embodiment, the application program is acquired from the application server 110, but may be acquired from a recording medium such as a BD-ROM or DVD.
