For application programs created by one individual's hobby, operation guarantees can only be made 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 simple, it is still good, but in some cases, running the application program may lead to a failure of the device that executed the application program.

 [0007] 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.

 Means for solving the problem

[0008] 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 acquisition means for acquiring the operation result information to be shown, and processing means for performing processing relating to the application program based on the operation result information.

[0009] Here, the playback device is one of the mass-produced products, and the same type of device as the own device is a device other than the one that is mass-produced! A device with specifications. In addition, the processing performed by the processing means here is, for example, executed by the own device when it is determined that the application program can be executed or when it is determined that the application program can be installed. Installed, or when it is determined that the application program can be acquired, or the contents of the operation result information are displayed. One of the processes is performed. It is not necessary for one playback device to execute all of the processing examples listed here.

 The invention's effect

 [0010] With the configuration described above, before operating the application program that the user is trying to acquire on the playback device, the operation results when the application program is operated on the same type device other than the own device are shown. Based on this, it becomes possible to determine the response to application programs.

 In addition, the operation result information is information on the frequency of occurrence of a malfunction in the same type of device as that of the own device when the application program is executed in the same type of device as the own device, or the same type of device as the own device. Contains information on the number of faults that occurred or information on the status of faults that occurred in the same type of equipment as the device, and the processing means responds to the frequency of occurrence of the faults or the number of faults uttered. Change the content of the process.

 [0011] Thereby, the playback apparatus can perform the processing of the application program, for example, whether or not to execute the application program, using the occurrence frequency of defects including the failure frequency as a determination material.

 In addition, the playback apparatus 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 a device of the same type as its own device; Application information acquisition means for acquiring information related to the application program that is about to be executed by the own device, and the operation result information acquisition means corresponds to information related to the application program from the operation result information storage means. You can get it by reading the operation results information! / ,.

 [0012] Thereby, the playback device can acquire the operation result information from the memory inside the own device and refer to it. When the own machine has sufficient memory capacity, the own machine stores the operation result information, and almost all processing can be performed only by the own machine.

In addition, the playback device further includes a communication unit that communicates with an external device, and includes an application information acquisition unit that acquires information about the application program, Own operation information storage means for storing information to be stored, and the operation result information obtaining means obtains operation result information corresponding to the information related to the application program and the information related to the own device via the communication means. It is also possible to acquire the external device power by storing each operation result information corresponding to a plurality of different application programs when each device is operated on the same type of device as the own device.

 [0013] With this, when the own device does not store the operation result information, the playback device uses information identifying the application program such as the name of the application program and information such as the model number identifying the own device. In addition, the corresponding operation performance information can be stored and obtained from an external server! Storing all the application programs and operation history information of the own device is a huge amount of information, and this places a burden on the memory of the own device. By adopting this configuration, it is possible to reduce the memory load of the device itself, and to use the memory capacity that can be freed up by not storing all operation performance information for other purposes such as holding video content. .

 [0014] In addition, the operation result information includes the frequency of occurrence of a failure that occurs in the same type of device as the own type when the application program is operated on the same type of device as the own device. Is information indicating the number of occurrences, and the playback apparatus may further execute or install an application program, and whether or not it may be acquired is determined based on the occurrence frequency of the failure. Reference information indicated according to the number of cases may be stored in advance, and a reference information storage unit may be provided to perform processing related to the application based on the operation result information and the reference information.

 [0015] This makes it possible for the playback device to determine whether or not the application program can operate on its own device in comparison with the operation result information acquired based on the determination criterion information.

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 executed according to the occurrence frequency or the number of occurrences of the defect. The processing means determines that the application program acquired by the application acquisition means may be executed based on the operation result information and the reference information. If this happens, it can be executed on your own machine.

 [0016] Thereby, the playback device can execute the application when it is determined that the application program may be executed on the own device.

 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 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 device when it is determined that the application program can be installed based on the operation result information and the reference information. May be allowed.

 [0017] Thereby, the playback apparatus can install the application program when it is determined that the application program is operable on the own device. The application program to be acquired can be one that can be executed immediately because of its data format, or one that cannot be executed unless it is installed on its own equipment, and can be applied to application programs that require installation.

 [0018] In addition, the playback device further includes an application acquisition unit that acquires an application program, and the criterion information sets a criterion for determining whether or not the application program may be acquired based on the occurrence frequency or the number of occurrences of the defect. The processing means acquires the application program when it is determined that the application program that the application acquisition means is trying to acquire can be acquired based on the reference information. Yo ...

 [0019] Thereby, when the application program is not yet acquired, it is possible to determine whether the application program to be acquired on the own device can operate on the own device. However, when the application program is acquired via the network, the communication cost can be reduced.

 The reproducing apparatus may further include display means for displaying the contents of the operation result information acquired by the operation result information acquisition means.

[0020] Thereby, the playback device can present the contents of the acquired operation result information to the user, and can leave the user with a determination as to whether to execute the application program on the own device. You can. In addition, in the operation result information, it is considered 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 apparatus capable of acquiring and executing an application program, the acquisition step for acquiring information related to the application program, and the playback apparatus based on the information related to the application program Based on the operation result information acquisition step for acquiring the operation result information indicating the operation result when the application program is operated in the same type of device and the operation result information acquired in the operation result information acquisition step !, And processing steps for processing the application program.

The PES packet obtained by the conversion also has a function of outputting a packet having a desired PID to the font generator 250, the I-Graphics decoder 251, and the audio decoder 261.

 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 device. 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 represented by a 16-bit YUV value. In video plane 5, the playback video for each frame in the video stream can be scaled. Scaling is to change the playback image for each frame to either 1/4 (referred to as quota) or 1/1 (referred to as 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 fully displayed.

 User processing unit 290 receives an instruction from a user via a remote controller or the like, and outputs the content to CPU 205.

 Data>

Here, data used to determine whether the BD player 100 executes or installs an application program will be described. [0040] 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.

 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.

 [0041] 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. Adaptation 303 indicates whether the application program is actually executable or installable on the device, and if so, the frequency of malfunction is shown in malfunction 304. Adaptation 303 may be “possible” and “impossible”, and malfunction 304 has five levels of “none”, “rare”, “small”, “medium”, “many”, and malfunctions in this order. Indicates that it will increase. This stage is based on reports of malfunctions between the same model and application program received from the user.For example, the number of failures is “no” for SO, “rare” for 1 to 5, and “rare” for 5 to 10. “Low”, 10 forces and 30 are defined as “medium”, and more than that “high”. This setting may differ depending on each application program and each device. The information of the malfunction 304 is sequentially updated by the administrator of the operation result holding server 120. When adaptation is not possible, the application program does not run on the device, so “1” is written in the column of malfunction.

 In the operation record information 300, for example, in the case of “application program Averl.00”, the operation record with the device “DVD B” is “adaptive: acceptable, poor operation: small”.

 Next, the data indicating the criteria for determining whether the BD player 100 may execute or install the application program will be described with reference information 233 in FIG.

[0043] The BD player 100 holds the reference information 233 in the built-in ROM 230, and as shown in FIG. In each case, whether or not to execute or install 402 is shown. Where applicable, it is determined by each malfunction stage. If it is not applicable, it cannot be executed or installed. Next, information that is held by the application program and transmitted from the BD player 100 to the operation record holding server 120 will be described.

 In addition to the main body of the application program, the application program includes information such as the name of the application program, version information, data size, file type, etc. in the header part. The name of this application program and its version information are extracted. The BD player 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.

 [0045] Also, the BD player 100 stores in the ROM 230 the data related to its own device, for example, the type of device, the strength developed by any effort, and the model number set by the manufacturer. This 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 result holding server 120 can identify the BD player 100 and search the operation result information 300 by combining it with the information of the application program.

<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 the application program acquisition request by the user processing unit 290 by the operation of the user's remote controller or the like 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, that is! /, To the BD player 100 with its compressed archive (step S502).

[0047] 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 record holding server (step S503). The operation record holding server 120 that has received the BD player information and the application program information stores the operation record information 300 that conforms to the two pieces of information. The operation result information corresponding to the retrieved information is returned to the BD player 100 (step S504). The BD player 100 that has acquired the operation result information determines whether it can execute or install the application program according to the reference information 233 stored by itself (step S505), and then executes the subsequent application program. Or, if installation is possible, the application program is executed.

 Next, the operation of the BD player 100 according to the present embodiment will be described with reference to 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 the 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. Header part strength of retained application program The name and version information of the application program are extracted, and information indicating the name and model number of the own machine is read from the ROM 230. Send via 201. In response to the transmission, the operation result information that is a reply from the operation result information holding server 120 is received (step S605). This operation result information is information obtained by extracting only the part corresponding to the BD player 100 and the application program acquired by the BD player 100 from the operation result holding server 120 operation result information 300.

[0049] Then, the reference information 233 is read from the ROM 230 (step S607). Based on the information on whether or not the acquired operation result information can be applied and the frequency of occurrence of operation failure when it is possible, It is determined whether or not the application program can be executed or installed in comparison with the reference information 233 (step S609). First, when the adaptation is “impossible”, it is determined that the application program cannot be executed on its own and cannot be executed or installed. Next, when the adaptation is “permitted”, it is determined that the execution or installation is possible when the information of the operation failure 304 is seen and when it is “none”, “rare”, or “low”. Otherwise, it is determined that it cannot be executed or installed. For example, if your device is BD B and the acquired application program is app A 1 John 1. 44. In this case, the operation result information to be acquired is `` adaptive: acceptable, poor operation: low '', so in this case, the CPU 205 determines that it should be executed by executing the application program against the reference information 233. .

[0050] When it is determined that the application program is to be installed or executed, the application program is started and playback of images and the like by the application program is started (step S611). If it is determined that the application program cannot be installed or executed, the application program is also deleted (step S613). The above is the operation when the BD player 100 acquires the application program.

 [0051] Finally, the flow of simply executing the application program will be briefly described with reference to the functional block diagram of FIG. Here, it is assumed that this application program is an application program that displays a subtitle, for example, by using a part of the scene in the moving image content A.

 First, the BD player 100 that has received an application program activation instruction from the user in the user processing unit 290 reads the application program from the local memory.

 [0052] In addition to the GUI or graphics presented to the user, the application program holds a playlist that indicates which part of the video content A used in the application program is to be used at which timing. The video content A shown in the above is extracted and displayed at the timing indicated by the application program. The video 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 playlist, while the GUI and character data provided by the application program are sequentially stored in the graphics plane 270. Then, the image power synthesized by the synthesizing units 282 and 283 is displayed on a monitor connected to the D player 100.

In addition to subtitles, the application program includes a visual novel game that uses a part of the video content scene, and license management for video content. Allowing playback of video content · A program that determines whether or not to permit playback is assumed. <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 assumed to be a BD player. Any player that can acquire and execute an application program can be used, such as a DVD player that can execute an application program. Also good.

 (2) In the above embodiment, the power that is obtained from the operation result information from the operation result holding server 120 may be held by the BD player 100 as long as the BD player 100 has a sufficient storage capacity. This saves the trouble of communicating with the operation record holding server 120 and eliminates communication costs.

 (3) In the above embodiment, the operation result information 300 indicates whether or not the application program can be applied to the device and the frequency of occurrence of operation failure corresponding to the application program and the device. However, the contents described in the operation result information 300 are not limited to this. Anything related to malfunction may be used. For example, a remarks column showing details of the situation in which the malfunction occurs may be provided. The contents written in the remarks column may be presented to the user so that the user can determine whether to execute the application program.

(4) In the above embodiment, the application program is acquired, the application program power is extracted, and information such as the name and version of the application program is extracted and transmitted to the operation result holding server 120. It is also possible to obtain only the information of the application program from the application server 110, which is not an application program, and check whether the operation is possible before obtaining the application program main body. If a serious problem occurs in this case, before acquiring the application program itself, cancel the acquisition, or display the G UI to the user and propose to cancel it. As a result, when an application program is acquired via the network, the application program is downloaded unnecessarily. This eliminates unnecessary communication costs.

 (5) In the embodiment described above, the BD player 100 itself determines whether the power can be executed or installed. The BD player 100 acquires the operation result information, and the contents are connected to the BD player. It may be displayed only on a monitor or the like, and the user may be allowed to determine whether or not the application program can be executed. In this case, the user processing unit is selected using a remote controller attached to the BD player from the user, and the user processing unit receives the signal and processes the application program in accordance with the contents of the instruction. In addition, when detailed failure details are described in the operation result information, it can be used to determine whether or not to execute the application by referring to it.

 (6) In the above embodiment, there is only one operation result holding server. For example, each device manufacturer may manage to manage each operation result information. In this case, the playback device shall store the address of the operation result holding server of the manufacturer that manufactured the device, and acquire the operation result information.

 (7) In the above embodiment, the determination criterion is set in advance, but this may be changed by the user using a remote control 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, but the operation failure information is collected and the number of operation failures is counted to automatically Specifically, the operation result holding server 120 may update the operation result information 233. In this case, the operation result holding server 120 needs to store information for determining “rare”, “small”, “medium”, and “many” in accordance with the number of malfunctions that have risen. For example, if the number of malfunctions is 5 or less, the information is “rare”.

(9) In the above embodiment, the BD player 100 identifies the application program that is trying to acquire the application program name, etc., that is determined to determine whether the operation is possible when the application program is acquired. Acquire only information, send it to the operation result holding server, and if it is determined that operation is not possible, suppress acquisition of the application program itself. It is good also as calling attention. This is considered to be effective in terms of both time and communication cost, such as when the download time is significant when the capacity of the application program is large.

 (10) In the above embodiment, the operation failure information 300 column of the operation result information has five levels of “none”, “rare”, “small”, “medium”, and “many”. It may be the number of occurrences or the percentage of failures that occurred relative to the number shipped. In the case of the number of failure occurrences, it is necessary to include information in the standard information that execution is possible if the number of failure occurrences is less than or equal to! / ヽ can be installed. In the case of a percentage, it is necessary to include information on the threshold value of whether installation is possible or not in the reference information.

 (11) In the above embodiment, the application program is obtained from the application server 110. The application program is recorded from a BD-ROM that records the application program, or from a recording medium such as a DVD. Moyo.

 (12) In the above embodiment, the application program is assumed to be written in Java (registered trademark). This may be written in another programming language. Other programming languages include programming languages such as C or C ++.

 (13) The present invention may be a method for determining whether or not an application can be executed or installed on a playback device or the like in the above embodiment. Further, the present invention may be a computer program for causing a computer of the playback apparatus to execute the processing procedure described in this method. The computer program may be recorded on various recording media such as FD (Flexible Disc), MO (Magneto-Optical disc), CD (Compact Disc), DVD, BD, and hard disk drive.
