<First Embodiment>
Hereinafter, an embodiment of the output control program will be described with reference to FIGS. 1 and 2.
In the present embodiment, as shown in FIG. 1, it is assumed that the client terminal 20 reproduces a plurality of contents based on the file (markup language file) acquired from the server 10.

The client terminal 20 used by the user is connected to the server 10 via a network. The server 10 includes a file storage unit 12.
The file storage unit 12 stores a file to be provided to the client terminal 20. Here, a file described in the markup language is recorded. As will be described later, this file includes a description (output control program) for realizing various means in the client terminal 20. In the present embodiment, a description for realizing the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215, which will be described later, is included.

Further, this file contains information (content information) regarding a plurality of contents used at the time of output. The content information includes information regarding the acquisition destination of the content such as audio and video. Here, the acquisition destination is the address information (for example, URL: Uniform Resource Locator) in which the object that can be provided is stored when this item is used.
Further, the file contains the main / sub setting information for identifying either the main content or the sub content in each content.

The client terminal 20 is a computer (information processing terminal such as a smartphone) used by a user who browses a file, and functions as an output control 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 this embodiment, a browser (program) that displays a file described in the markup language is stored.
The input / output unit 23 is composed of 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 file acquisition means 211 and an output processing means 212.

The file acquisition means 211 reads a file (markup language file).
The output processing means 212 outputs the markup language file as a web page to the input / output unit 23.

Further, the browser 210 executes the description contained in this file. By executing this description, the control unit 21 functions as the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215. Specifically, the file acquisition means 211 of the browser 210 acquires JavaScript (registered trademark) stored in the file storage unit 12 of the server 10. Then, based on the description of this JavaScript (registered trademark), the control unit 21 causes the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215 to function.

The ducking management means 213 detects the necessity of the ducking process.
The main / sub-identifying means 214 identifies the main content or the sub-content for a plurality of contents used for file reproduction.

The output condition setting means 215 sets the output condition when the main content and the sub content are output at the same time. The output condition setting means 215 holds information on the output conditions (output level) of the main content and the sub-content when the main content and the sub-content are output at the same time. For example, in the case of audio-related content, information regarding a setting for increasing the volume ratio between the main content and the sub-content is stored. As a result, the main content can be made to stand out with respect to the sub-content.

Next, the process of outputting the content included in the file on the client terminal 20 will be described with reference to FIG.
First, the control unit 21 of the client terminal 20 executes a file reading process (step S1-1). Specifically, the URL of the file to be output is input to the browser 210 via the input / output unit 23. In this case, the browser 210 requests the contents of the URL from the server 10 by the file acquisition means 211. Then, the browser 210 acquires the file from the server 10. Here, it is assumed that a markup language file is acquired as a file. This file contains a description for realizing the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215. In addition, this file contains information about the content (eg, audio) used for output.

Next, the control unit 21 of the client terminal 20 executes a file reproduction process (step S1-2). Specifically, the output processing means of the browser 210 of the control unit 21 outputs the file acquired from the server 10. Here, when outputting a single content included in the file, the content is played as it is.

In this case, the control unit 21 of the client terminal 20 executes the ducking process.
In this ducking process, first, the control unit 21 of the client terminal 20 executes the event standby process (step S2-1). Specifically, the browser 210 of the control unit 21 waits for an event in which a plurality of contents are output at the same time by the ducking management means 213.

When an event in which a plurality of contents are output at the same time is detected, the control unit 21 of the client terminal 20 executes a determination process as to whether or not ducking is necessary (step S2-2). Specifically, the browser 210 of the control unit 21 causes the ducking management means 213 to confirm the presence / absence of the main / sub setting information for the plurality of contents included in the file. Then, when the main / sub setting information is included, it is determined that ducking is necessary.

When it is determined that ducking is not necessary (when "NO" in step S2-2), the event waiting process (step S2-1) is continued.
On the other hand, when it is determined that ducking is necessary (when "YES" in step S2-2), the control unit 21 of the client terminal 20 executes the process of specifying the main / secondary content (step S2-3). Specifically, the browser 210 of the control unit 21 identifies the main content by the main / sub-identifying means 214 based on the main / sub-setting information included in the file.

Next, the control unit 21 of the client terminal 20 executes a process of changing the output conditions of the main / sub-contents (step S2-4). Specifically, the browser 210 of the control unit 21 acquires preset output conditions by the output condition setting means 215 and changes them to these output conditions. For example, in the case of audio content, the output condition is changed so that the volume of the main content is increased and the volume of the sub content is decreased.

Next, the control unit 21 of the client terminal 20 executes a determination process as to whether or not the ducking is completed (step S2-5). Specifically, the browser 210 of the control unit 21 waits for the end of the event in which a plurality of contents are output at the same time by the ducking management means 213.

When it is determined that the ducking is not completed (in the case of "NO" in step S2-5), the changed output condition is maintained.
On the other hand, when it is determined that the ducking is completed (when "YES" in step S2-5), the control unit 21 of the client terminal 20 executes a process of restoring the output condition (step S2-6). Specifically, the browser 210 of the control unit 21 causes the output condition setting means 215 to restore the changed output condition. For example, in audio content, the lowered volume is raised to return to the original volume.

Next, an example of a code (program) to be included in a file (markup language file) and provided to the client terminal 20 will be described with reference to FIGS. 3 and 4. Here, it is assumed that the code written using JavaScript (registered trademark) is provided. In this code example, it is assumed that ducking is performed in audio content. Hereinafter, this code will be described separately in two first parts 500 (FIG. 3) and second part 510 (FIG. 4).

The first part 500 shown in FIG. 3 includes descriptions 501 to 507.
In description 501, an object "scene" is generated based on the object "AudioScene".

In the description 502, in the object “scene”, the environmental sound (“EnvironmentSound-1”, “EnvironmentSound-2”) and the voice of the character (“Speech”) are added in the scene.

In description 503, the environmental sound is reproduced.
In description 504, the voice of the character is reproduced. When reproducing the voice of the character, ducking is performed as described later.

In the description 505, a low volume determination function that returns a low volume (output condition) as a return value is set, and in the description 506, a loud volume determination function that returns a high volume (output condition) as a return value is set.
In description 507, in description 502, a function that adds sound to the scene is set.

The second part 510 shown in FIG. 4 includes descriptions 511 to 515 for ducking.
In description 511, the primary sound (main voice) is determined. Here, the character's voice (“Speech”) is used as the main voice.

In description 512, all sounds contained in the scene are manipulated based on description 502.
In description 513, when the primary sound (main sound) is acquired, this sound is reproduced using a loud volume according to the length of the main sound.

In description 514, the volume of the secondary (secondary sound) is restored when the reproduction of the primary sound (main sound) is completed.
On the other hand, in the description 515, a sound other than the primary sound, that is, a secondary sound (secondary sound) is reproduced using a small volume.

According to this embodiment, the following effects can be obtained.
(1) In the present embodiment, the file includes a description for realizing the ducking management means 213. The ducking management means 213 detects an event that outputs a plurality of contents at the same time in the reproduction of the file. As a result, ducking processing can be performed in the reproduction of the content.

(2) In the present embodiment, the file includes a description for realizing the main / sub-identifying means 214 and the output condition setting means 215. The main / sub-identifying means 214 identifies the main content or the sub-content for a plurality of contents used for file reproduction. Further, the output condition setting means 215 sets the output condition when the main content and the sub content are output at the same time. As a result, it is not necessary to prepare a content material in which the main content and the sub-content are set in advance according to the output conditions, and the ducking process can be performed efficiently. Therefore, even in an application in which the output state and playback time of the content are determined at the time of playback, ducking can be performed without processing the content material.

<Second embodiment>
Next, a second embodiment of the output control program will be described with reference to FIG. In the first embodiment, preset output conditions are used in the ducking process. In the second embodiment, in the ducking process, the output conditions are determined according to the playback environment of the file (content), and the description of the same parts will be omitted.

In this case, the output condition setting means 215 operated by the output control program specifies the reproduction environment information. For example, the surrounding environment information is acquired as the reproduction environment information by using a sensor (microphone, CCD, etc.) provided in the client terminal 20. This ambient environment information is, for example, information on the noise level and brightness of the place where the client terminal 20 is used. Then, the output condition setting means 215 holds an output condition determination table for determining the output condition corresponding to the surrounding environment information. In this output condition determination table, for example, output conditions (for example, volume of main / sub contents) according to a noise level are recorded. In addition, output conditions (for example, brightness and contrast of the main / sub contents) according to the brightness level are recorded.

Next, the ducking process in the present embodiment will be described with reference to FIG.
Here, the control unit 21 of the client terminal 20 performs an event standby process (step S3-1) and a determination process (step S3-2) as to whether or not ducking is necessary, as in steps S2-1 and S2-2. Execute.

When it is determined that ducking is not necessary (when "NO" in step S3-2), the event waiting process (step S3-1) is continued.
On the other hand, when it is determined that ducking is necessary (when "YES" in step S3-2), the control unit 21 of the client terminal 20 executes the main / sub-content identification process as in step S2-3 (step). S3-3).

Next, the control unit 21 of the client terminal 20 executes a process for specifying the playback environment (step S3-4). Specifically, the browser 210 of the control unit 21 acquires information on the playback environment of the client terminal 20 that reproduces the content by the output condition setting means 215.

Next, the control unit 21 of the client terminal 20 executes a process of changing the output conditions of the main / sub-contents according to the playback environment (step S3-5). Specifically, the browser 210 of the control unit 21 specifies the output conditions corresponding to the reproduction environment by using the output condition determination table by the output condition setting means 215. Then, the output conditions for reproducing the main / sub-contents in the output processing means 212 are changed.

Next, the control unit 21 of the client terminal 20 executes a determination process as to whether or not the ducking is completed (step S3-6), as in step S2-5. When it is determined that the ducking is not completed (in the case of "NO" in step S3-6), the control unit 21 of the client terminal 20 maintains the changed output condition.

On the other hand, when it is determined that the ducking is completed (when "YES" in step S3-6), the control unit 21 of the client terminal 20 executes a process of restoring the output condition (step), as in step S2-6. S3-7).

In the present embodiment, in the object "Audio Scene" shown in FIG. 3, the volume is adjusted according to the playback environment in the descriptions 505 and 506. For this purpose, the object "AudioScene" includes a description for acquiring information about the playback environment. Then, in the description 505, a low volume (output condition) corresponding to the playback environment is returned as a return value by using a low volume determination function with the playback environment information as a variable. Further, in the description 506, a loud volume (output condition) corresponding to the playback environment is returned as a return value by using a loud volume determination function using the playback environment information as a variable.

According to this embodiment, the following effects can be obtained.
(3) In the present embodiment, the control unit 21 of the client terminal 20 executes a process of changing the output conditions of the main and sub contents according to the playback environment (step S3-5). As a result, ducking can be performed according to the playback environment.

The above embodiment may be changed as follows.
-In each of the above embodiments, for example, audio content is used, but the content is not limited to audio. It is also possible to use various media contents such as still image contents and video contents. In this case, for example, the object "MediaScene" is used instead of the object "AudioScene". Then, this object executes a function (for example, "setOutputLevel") that changes the output conditions such as the brightness and contrast of the image. For example, in the ducking process, the main content is brightened or the contrast is emphasized.

-In each of the above embodiments, the file includes a description for realizing the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215. This description is not limited to inclusion in the file. The acquisition destination may be set in the file, and the description may be acquired from this acquisition destination.

-In each of the above embodiments, the file includes main / sub setting information for specifying either the main content or the sub content in each content. In this case, the main content or the sub-content is not limited to the fixed case, and the main content or the sub-content may be changed depending on the situation. In this case, the main / sub determination condition that is the main content is set in the main / sub setting information. In this main / sub-determination condition, the logic for determining the main content and the sub-content is set in relation to the situation. Then, when an event is detected, the main content and the sub-content are determined using the main / sub-determination condition. Thereby, the relationship between the main and the sub can be determined when the file is played back.

-In the second embodiment, the output condition setting means 215 specifies the reproduction environment information. For example, the surrounding environment information (reproduction environment information) is acquired by using a sensor (microphone, CCD, etc.) provided in the client terminal 20. The reproduction environment information is not limited to the surrounding environment information. For example, the file playback scene (scene on the scenario) in which the event occurred may be specified as the playback environment information. In this case, the output condition is set in the output condition setting function in association with the scene information in which the event occurred.

It is also possible to use the configuration information of the hardware configuration and the software configuration mounted on the client terminal 20 as the playback environment information. In this case, the output condition is set in the output condition setting function in association with the configuration information of the hardware configuration and software configuration. Then, the output condition setting means 215 acquires the configuration information of the hardware configuration and the software configuration, and calculates the output condition based on the configuration information.

Further, it is also possible to use the reproduction frequency of the content as the reproduction environment information. In this case, the output condition setting means 215 records the number of times of reproduction for each content. Then, the output condition is set in the output condition setting function in association with the number of playbacks. For example, when the number of playbacks increases, the output level is lowered by lowering the volume of this content or weakening the contrast. As a result, it is possible to adjust the content with many repetitions.

-In the second embodiment, when it is determined that the ducking is not completed (when "NO" in step S3-6), the control unit 21 of the client terminal 20 maintains the changed output condition. Instead of this, the output conditions of the main and sub contents at the time of ducking may be changed sequentially. Here, when it is determined that the ducking is not completed (when “NO” in step S3-6), the control unit 21 of the client terminal 20 returns to the reproduction environment specifying process (step S3-4). This makes it possible to dynamically change the output conditions over time.

In each of the above embodiments, the client terminal 20 executes the output control program to cause the control unit 21 to function as the ducking management means 213, the main / sub-identifying means 214, and the output condition setting means 215. Here, the environment for executing the output control program is not limited to the client terminal 20. For example, the output control program may be executed on the management server connected to the client terminal 20 that outputs the content. In this case, the management server acquires the content output status information and the playback environment information from the client terminal 20, and determines the content output conditions using these information. Then, the client terminal 20 outputs the content according to this output condition.
Next, the technical idea that can be grasped from the above embodiment and another example will be added below.
