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

A client terminal 20 used by a user is connected to the server 10 via a network. This server 10 has a file storage unit 12 .
A file to be provided to the client terminal 20 is stored in the file storage unit 12 . Here, a file written in markup language is recorded. This file contains descriptions (output control programs) for realizing various means in the client terminal 20, as will be described later. In this embodiment, the ducking management means 2 described later
13. Include a description for realizing the main/sub specifying means 214 and the output condition setting means 215 .

In addition, this file contains information (content information) on multiple contents to be used at the time of output. The content information includes information relating to acquisition sources of content such as audio and video. Here, the acquisition destination is address information (for example, URL: Uniform Resource Locator) storing an object that can be provided when using this item.
Furthermore, the file includes main and sub setting information for specifying either main content or sub content in each content.

The client terminal 20 is a computer (information processing terminal such as a smart phone) used by a user who browses files, and functions as an output control device. The client terminal 20 includes a control unit 21 composed of a CPU, memory (RAM and ROM), etc., 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) for displaying files written in a markup language is stored.
The input/output unit 23 is configured by a touch panel display or the like, and performs data output and input.

The control unit 21 activates the browser 210 by executing the browser program stored in the terminal storage unit 22 . This browser 210 comprises file acquisition means 211 and output processing means 212 .

File acquisition means 211 reads a file (markup language file).
The output processing means 212 converts the markup language file into a web page and outputs it to the input/output unit 2.
Output to 3.

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

Ducking management means 213 detects the necessity of ducking processing.
The main/sub-specifying means 214 specifies main contents or sub-contents for a plurality of contents to be 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 regarding the output conditions (output levels) of the main content and the sub-contents when the main content and the sub-contents are output at the same time. For example, in the case of audio-related content, information is held regarding settings for increasing the volume ratio between the main content and the sub-content. This makes it possible to make the main content stand out from the sub content.

Next, with reference to FIG. 2, a process of outputting content included in a file at the client terminal 20 will be described.
First, the control unit 21 of the client terminal 20 executes file reading processing (step S1-1). Specifically, the URL of the desired output file is input to the browser 210 via the input/output unit 23 . In this case, the browser 210 requests the content of the URL from the server 10 using the file acquisition means 211 . The browser 210 then acquires the file from the server 10 . Here, it is assumed that the file is a markup language file. This file includes descriptions for realizing the ducking management means 213 , main/sub specifying means 214 , and output condition setting means 215 . Additionally, this file contains information about the content (eg, audio) to use when outputting.

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

In this case, the control unit 21 of the client terminal 20 executes ducking processing.
In this ducking process, first, the control unit 21 of the client terminal 20 executes event waiting 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 simultaneously by the ducking management means 213 .

When detecting an event in which multiple contents are output at the same time, the client terminal 20
The control unit 21 executes determination processing as to whether or not ducking is necessary (step S
2-2). Specifically, the browser 210 of the control unit 21, the ducking management means 213,
Check the existence of primary and secondary setting information for multiple contents included in the file. Then, if the primary and secondary setting information is included, it is determined that ducking is necessary.

If it is determined that ducking is not necessary ("NO" in step S2-2)
, the event standby process (step S2-1) is continued.
On the other hand, if it is determined that ducking is necessary ("YES" in step S2-2), the control unit 21 of the client terminal 20 executes main and sub-content specifying processing (step S2-3). Specifically, the browser 210 of the control unit 21 uses the main/sub-specification unit 214 to specify the main content based on the main/sub-setting information included in the file.

Next, the control section 21 of the client terminal 20 executes a process of changing the output condition of the main and sub contents (step S2-4). Specifically, the browser 210 of the control unit 21 acquires a preset output condition by the output condition setting means 215, and changes the output condition to this output condition. For example, in the case of audio content, the output condition is changed to increase the volume of the main content and decrease the volume of the sub-content.

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

If it is determined that ducking is not completed ("NO" in step S2-5),
Maintain modified output conditions.
On the other hand, if it is determined that the ducking is completed ("YES" in step S2-5)
, the control unit 21 of the client terminal 20 executes processing for restoring the output conditions (step S2-6). Specifically, the browser 210 of the control unit 21, the output condition setting means 215,
Undo the changed output conditions. For example, in audio content, a lowered volume is raised back to the original volume.

Next, an example of a code (program) included in a file (markup language file) and provided to the client terminal 20 will be described with reference to FIGS. 3 and 4. FIG. Here, Ja
Assume that a code written using JavaScript (registered trademark) is provided. This code example assumes that ducking is performed on audio content. This code is divided into two parts, a first part 500 (Fig. 3) and a second part 510 (Fig. 4).

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

In the description 502, in the object "scene", the environmental sound ("Envir
onmentSound-1", "EnvironmentSound-2") and the character's voice ("Speech").

Description 503 reproduces environmental sounds.
At statement 504, the character's voice is played. When reproducing the voice of the character, ducking is performed as described later.

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

The second part 510 shown in FIG. 4 contains descriptions 511-515 for ducking.
Description 511 determines the primary sound (main sound). Here, the voice of the character ("Speech") is used as the main voice.

Description 512 manipulates all sounds contained in the scene based on description 502 .
In description 513, when the primary sound (main sound) is acquired, this sound is played back using a large volume according to the length of the main sound.

In description 514, the volume of the secondary (auxiliary audio) is restored when the primary sound (main audio) finishes playing.
On the other hand, in description 515, sounds other than the primary sound, that is, the secondary sound (auxiliary sound) are reproduced using a low volume.

According to this embodiment, the following effects can be obtained.
(1) In this embodiment, the file includes a description for realizing the ducking management means 213 . The ducking management unit 213 detects an event of simultaneously outputting a plurality of contents during file reproduction. As a result, the ducking process can be performed in reproducing the content.

(2) In this embodiment, the file includes a description for realizing the main/sub specifying means 214 and the output condition setting means 215 . This main/sub-specifying means 214 specifies main contents or sub-contents for a plurality of contents to be used for file reproduction. Also, 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 content are determined at the time of playback, ducking can be performed without processing the content material.

<Second embodiment>
Next, according to FIG. 5, a second embodiment of the output control program will be described. 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 reproduction environment of the file (content), and the description of the same parts will be omitted.

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

Next, referring to FIG. 5, ducking processing in this embodiment will be described.
Here, similarly to steps S2-1 and S2-2, the control unit 21 of the client terminal 20 performs event waiting processing (step S3-1) and determination processing as to whether or not ducking is necessary (step S3-2). Run.

If it is determined that ducking is not necessary ("NO" in step S3-2)
, the event standby process (step S3-1) is continued.
On the other hand, if it is determined that ducking is necessary ("YES" in step S3-2), the control unit 21 of the client terminal 20 executes the process of specifying the main and secondary content (step S2-3). S3-3).

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

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

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

On the other hand, if it is determined that the ducking is completed ("YES" in step S3-6)
As in step S2-6, the control unit 21 of the client terminal 20 executes processing for restoring the output conditions (step S3-7).

In this embodiment, the descriptions 505 and 50 in the object "AudioScene" shown in FIG.
At 6, the volume is adjusted according to the reproduction environment. For this, the object "AudioScene"
, include a description to obtain information about the playback environment. Then, in description 505, a low volume (output condition) corresponding to the reproduction environment is returned as a return value using a low volume decision function having reproduction environment information as a variable. Also, in the description 506, a large sound volume (output condition) corresponding to the reproduction environment is returned as a return value using a large sound volume determination function having the reproduction environment information as a variable.

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

Note that the above embodiment may be modified 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 moving image contents. In this case, instead of the object "AudioScene", for example, the object "MediaScene" is used. And in this object, functions that change the output conditions such as brightness and contrast of the image (for example, "setOutputLevel"
). For example, the ducking process brightens the main content or enhances the contrast.

- In each of the above embodiments, the file contains the ducking management means 213, the main/sub identification means 21,
4. Include a description for realizing the output condition setting means 215 . This description is not limited to inclusion in the file. An 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 and sub setting information for specifying either the main content or the sub content in each content. In this case, the main content or sub-content is not limited to being fixed, and the main content or sub-content may be changed according to the situation. In this case, in the main/sub setting information, the main/sub determining condition for the main content is set. In this main/sub-determination condition, a logic for determining main content and 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 and sub determination conditions. This makes it possible to determine the primary-secondary relationship during file playback.

- In the second embodiment, the output condition setting means 215 specifies the reproduction environment information. For example, surrounding environment information (playback environment information) is acquired using a sensor (microphone, CCD, etc.) provided in the client terminal 20 . The reproduction environment information is not limited to ambient environment information. For example, the file playback scene (scene in the scenario) where the event occurred,
It may be specified as reproduction 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 software configuration installed in the client terminal 20 as the reproduction 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 the 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 conditions based on this configuration information.

Furthermore, it is also possible to use the reproduction frequency of content as reproduction environment information. In this case, the number of reproduction times is recorded in the output condition setting means 215 for each content. and,
The output condition is set in advance in the output condition setting function in association with the number of playbacks. For example, when the number of playback times increases, the volume of the content is lowered, the contrast is lowered, or the output level is lowered. This makes it possible to adjust content that has many repetitions.

・In the second embodiment, when it is determined that the ducking is not completed (step S3-6
3), 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 sequentially changed. Here, if it is determined that the ducking is not finished (step S3-6
3), the control unit 21 of the client terminal 20 returns to the reproduction environment specifying process (step S3-4). This allows the output conditions to be dynamically changed over time.

- In each of the above-described embodiments, the output control program is executed in the client terminal 20 to cause the control section 21 to function as the ducking management means 213, the primary/secondary specifying means 214, and the output condition setting means 215. Here, the environment for executing the output control program is
It is not limited to the client terminal 20 . For example, an output control program may be executed in a management server connected to the client terminal 20 that outputs content. In this case, the management server acquires content output status information and reproduction environment information from the client terminal 20, and uses these information to determine the content output conditions. Then, the client terminal 20 outputs the content according to this output condition.
