Hereinafter, an embodiment of the object acquisition program will be described with reference to FIGS.
In the present embodiment, as shown in FIG. 1, the client terminal 20 acquires and reproduces an object (such as an audio file or a video file content) based on a document file (markup language file) acquired from the server 10. Assume that

The server 10 includes a document file storage unit 12 and an object storage unit 13.
The document file storage unit 12 stores a document file to be provided to the client terminal 20. This document file is described in a markup language. As will be described later, the document file includes descriptions for realizing various means in the client terminal 20. In the present embodiment, descriptions for realizing an environment information acquisition unit 212, an evaluation unit 213, and an object acquisition unit 214 described later are included.

  Further, the document file includes information (item information) related to items used at the time of output. Item information (object information means) is used to specify an acquirable object such as audio or a moving image. This item information includes information on the item ID, the acquisition destination, and the type.

Here, the item ID is an identifier (for example, “BGM”) for specifying an item used on the document file.
When the item is used, the acquisition destination is address information (for example, URL: Uniform Resource Locator) in which an object that can be provided is stored.
The type is the type of this object. For this type, for example, standards such as mpeg (Moving Picture Experts Group) and wave (standard data format of PCM (pulse code modulation sound source used in Windows (registered trademark))) can be used.

  The object storage unit 13 stores an object to be provided based on a document file (markup language file) in the client terminal 20. In this embodiment, as this object, for example, media content such as an audio file or a moving image file is used.

  The client terminal 20 is a computer (an information processing terminal such as a smartphone) used by a user who browses a document file, and functions as an object acquisition device. The client terminal 20 includes a control unit 21 including a CPU, a memory (RAM and ROM), a terminal storage unit 22, and an input / output unit 23.

Various settings and programs used in the client terminal 20 are recorded in the terminal storage unit 22. In the present embodiment, a browser (program) that displays a file written in a markup language is stored.
The input / output unit 23 is configured by a touch panel display or the like, and outputs and inputs data.

  The control unit 21 activates the browser 210 by executing the browser program stored in the terminal storage unit 22. The browser 210 includes a document file acquisition unit 211 and an output processing unit 215.

The document file acquisition unit 211 reads a document file (markup language file).
The output processing means 215 outputs the markup language file to the input / output unit 23 as a web page.

  Further, the browser 210 executes the description included in this document file. By executing this description, an environment information acquisition unit 212, an evaluation unit 213, and an object acquisition unit 214 are realized.

  The environment information acquisition unit 212 acquires information related to the environment of the client terminal 20. Here, hardware and software (terminal attributes) installed in the client terminal 20, information on the communication environment, terminal identification information, and the like are acquired.

The evaluation unit 213 evaluates the adaptability when the client terminal 20 outputs an object that can be acquired from the server 10. Here, as the object, for example, contents such as an audio file and a moving image file can be used. In order to evaluate the suitability, the evaluation unit 213 holds a predetermined evaluation logic using the environment information of the client terminal 20 and the object type as parameters. Then, the evaluation unit 213 records information on the evaluation result (best score, best object) in the memory for the available objects. Furthermore, the evaluation unit 213 holds data relating to a reference point for determining whether or not an object can be used.
The object acquisition unit 214 acquires the best object having the highest compatibility from the server 10.

  Next, with reference to FIG. 2, processing when the client terminal 20 outputs a document file will be described.

  First, the control unit 21 of the client terminal 20 executes a document file loading process (step S1-1). Specifically, the URL of the desired document file is input to the browser 210 of the control unit 21. In this case, the document file obtaining unit 211 of the browser 210 requests the server 10 for a URL document file. Then, the browser 210 acquires a document file from the server 10. Here, it is assumed that a markup language file is acquired as a document file. This document file includes descriptions for realizing the environment information acquisition unit 212, the evaluation unit 213, and the object acquisition unit 214. Further, the document file includes information on items (for example, BGM) used at the time of output.

  Next, the control unit 21 of the client terminal 20 executes usage environment information acquisition processing (step S1-2). Specifically, the browser 210 of the control unit 21 acquires the usage environment information in the client terminal 20 by the environment information acquisition unit 212. Here, for example, the operation system (OS) is specified in the system information held by the client terminal 20 that uses the document file as the usage environment information.

  Next, the control part 21 of the client terminal 20 performs the initialization process of the best object and the best score (step S1-3). Specifically, the browser 210 of the control unit 21 resets the best object and the best score recorded in the memory by the evaluation unit 213.

Then, an item included in the loaded document file is specified as a processing target item, and the following processing is repeated for each processing target item.
Here, first, the control unit 21 of the client terminal 20 executes an available object specifying process (step S1-4). Specifically, the browser 210 of the control unit 21 uses the evaluation unit 213 to identify an object prepared in the server 10 for the processing target item. In this case, an available object is identified based on item information set in the document file, and the following processing is repeated for each identified object.

  Here, the control unit 21 of the client terminal 20 executes a score calculation process according to the usage environment information (step S1-5). Specifically, the browser 210 of the control unit 21 uses the evaluation unit 213 to apply the evaluation logic to the object of the processing target item and calculate the score of this object.

Next, the control part 21 of the client terminal 20 performs the determination process about whether it is more than the existing best score (step S1-6). Specifically, the browser 210 of the control unit 21 repeatedly compares the calculated score and the best score recorded in the memory for each available object by the evaluation unit 213.
If it is determined that the calculated score is not equal to or higher than the best score (in the case of “NO” in step S1-6), the processing for this object is terminated.

On the other hand, when it is determined that the calculated score is equal to or higher than the best score (in the case of “YES” in step S1-6), the control unit 21 of the client terminal 20 executes update processing of the best object and the best score (step S1- 7). Specifically, the browser 210 of the control unit 21 records the object for which the score has been newly calculated by the evaluation unit 213 in the memory as the best object. Further, the calculated score is recorded in the memory as the best score. The above process is repeated for all available objects.
Then, the above process is repeated for all items included in the document file.

  Next, the control part 21 of the client terminal 20 performs the determination process about whether a best score is more than a reference point (step S1-8). Specifically, the browser 210 of the control unit 21 uses the evaluation unit 213 to compare the best score recorded in the memory and the reference point for each item.

  When it is determined that the best score is less than the reference point (in the case of “NO” in step S1-8), the control unit 21 of the client terminal 20 executes an alerting process (step S1-9). Specifically, the browser 210 of the control unit 21 outputs a message indicating that “there is no suitable object” for this item to the input / output unit 23.

  On the other hand, when it is determined that the best score is equal to or higher than the reference point (in the case of “YES” in step S1-8), the control unit 21 of the client terminal 20 executes the best object reading process (step S1-10). Specifically, the browser 210 of the control unit 21 uses the item information by the object acquisition unit 214 to specify the acquisition destination (URL) of the best object for this item. Then, an object is acquired from the server 10 using this acquisition destination.

  Next, the control unit 21 of the client terminal 20 executes an object execution process (step S1-11). Specifically, the browser 210 of the control unit 21 uses the output processing unit 215 to execute the acquired object.

  Next, a code (program) provided in the document file (markup language file) for the client terminal 20 will be described with reference to FIGS. Here, it is assumed that a “Manifest” object described using JavaScript (registered trademark) is provided. Here, one “Manifest” object is divided into three first parts 500 (FIG. 3), second part 510 (FIG. 4), and third part 520 (FIG. 5).

The first part 500 shown in FIG. 3 includes descriptions 501 to 503.
In the description 501, processing for returning a value is performed according to the environment of the client terminal 20. Here, in the case of the client terminal 20 using Android (registered trademark) as the OS, the value “true” is returned.

The descriptions 502 and 503 include a function for evaluating the object.
In the description 502, a function for assigning an evaluation score for the MP3 file (mpeg) is set. Here, a function is set for the MP3 file that gives “30” when the terminal attribute is an Android (registered trademark) terminal and “10” when the terminal attribute is a terminal with other terminal attributes.
In the description 503, a function for assigning an evaluation score for the PCM file (wave) is set. A function for assigning “20” is set for the PCM file.

  In the second part 510 shown in FIG. 4, prototypes “addURL” and “get” in “Manifest” are defined.

In the prototype “addURL”, item information (item ID, acquisition destination (URL), type) of an available object is defined.
In the prototype “get”, acquisition and implementation of an object with an item ID are defined.

  In the third part 520 shown in FIG. 5, a prototype “load” in “Manifest” is defined. Further, in the third part 520, a new object “Manifest” is generated based on the prototype.

The prototype “load” includes descriptions 521 to 525.
The description 521 realizes a function of resetting the memory for recording the best score and initializing the best score.

  The description 522 implements a function for evaluating an available object for each item using an evaluation logic. Based on the calculated score, the best score and the best item recorded in the memory are recorded and updated.

The description 523 realizes a function of outputting the evaluation result. Here, the object whose best score is recorded in the memory is output as the evaluation result.
In the description 524, usable objects are set. For example, in the case of audio, two audio files (“bgm.mp3” (MP3 format) and “bgm.wav” (PCM format)) are used for the item ID “BGM”.
The description 525 is a setting for downloading the best score object for each item using the URL of the item information.
The evaluation means 213 is realized by the descriptions 521 to 524, and the object acquisition means 214 is realized by the description 525.
