[Configuration of content playback system S]
FIG. 1 is a diagram showing a configuration of a content reproduction system S according to the present embodiment. The content reproduction system S has a plurality of content reproduction devices 1 and a content distribution device 2. The content playback device 1 and the content distribution device 2 transmit and receive various data via the network N. The network N includes, for example, the Internet or a mobile phone network.

The content distribution device 2 is a server that distributes moving image content to a plurality of content playback devices 1. The moving image content includes moving image data, sound data, and reproduction mode data used for determining a plurality of reproduction modes of the sound data. The moving image data is, for example, moving image data of a drama taken by a camera or moving image data of an animation created by a computer. The sound data corresponds to the moving image data, for example, the sound data emitted by the character included in the moving image data and the sound data emitted by the sound source included in the moving image data.

The reproduction mode data is data used for determining the volume, sound quality, timing, etc. when the content reproduction device 1 reproduces the sound data. The reproduction mode data includes, for example, relational data indicating the positional relationship between the position of the character included in the moving image content and the place where the sound is generated. The relationship data is, for example, coordinate data indicating the position of each character in the screen, or distance data indicating the distance between the characters. The reproduction mode data may include sound mode data indicating the mode of the sound corresponding to the character included in the moving image content. The sound mode data is, for example, data indicating at least one of volume, sound quality, and timing at which sound is emitted.

The content distribution device 2 has a storage medium for storing a plurality of moving image contents, and acquires the moving image contents from an external device such as a camera or a computer and stores the moving image contents in the storage medium. The content distribution device 2 may distribute the same video content to a plurality of content playback devices 1, or may distribute different video contents to a plurality of content playback devices 1.

A plurality of characters appear in video contents such as dramas and animations distributed by the content distribution device 2. The characters in the present specification are characters, animals, etc. appearing in dramas and animations. The moving image content includes, for example, reproduction mode data corresponding to each of a plurality of characters appearing in each scene. For example, in a scene in which the first character A and the second character B appear in the video content, the first reproduction mode data used for reproducing the sound heard at the position where the first character A is present and the position where the second character B is present. It includes a second reproduction mode data used for reproducing the audible sound.

The content reproduction device 1 is a terminal that reproduces moving image content distributed from the content distribution device 2, and is, for example, a computer, a smartphone, a tablet, or a head-mounted display. The content playback device 1 displays the moving image data included in the moving image content on the display, and outputs the sound data included in the moving image content from the speaker. The content reproduction device 1 reproduces the sound data based on the reproduction mode data corresponding to the sound heard at the position of the character selected by the user of the content reproduction device 1 among the plurality of reproduction mode data included in the moving image content.

FIG. 2 is a diagram for explaining a method in which the content reproduction device 1 reproduces sound data. FIG. 2A shows one scene of the moving image content, and includes images of the first character A (mouse), the second character B (dog), and the third character C (bird). It is assumed that the third character C is moving to the right with the passage of time.

FIG. 2B schematically shows the loudness of the sound heard at the position of the first character A. The horizontal axis of FIG. 2B shows time, and the vertical axis shows volume. At the position of the first character A, the voice a emitted by the first character A is reproduced at a louder volume than the voice b and the voice c emitted by the second character B and the third character C. Since the third character C moves from the left edge to the right edge of the screen, the voice c becomes louder as the third character C approaches the first character A, and becomes quieter after reaching the maximum at time T1.

FIG. 2C schematically shows the loudness of the sound heard at the position of the second character B. At the position of the second character B, the voice b emitted by the second character B is reproduced at a louder volume than the voices a and c emitted by the first character A and the third character C. Since the third character C moves from the left edge to the right edge of the screen, the voice c becomes louder as the third character C approaches the second character B, and becomes quieter after reaching the maximum at time T2.

Comparing FIG. 2B and FIG. 2C, it can be seen that the volume of each voice is different and the mode of change in the volume of voice c is different. By selecting a character that the user likes, the user can watch the video content while listening to the sound that can be heard at the position of the selected character, so that a high sense of presence can be obtained.

FIG. 3 is a diagram showing an example of reproduction mode data corresponding to the moving image data shown in FIG. In FIG. 3, the level of the volume when reproducing the sound emitted by each character is shown every second. "Large" indicates the loudest state among the three stages, "Medium" indicates the second loudest state, and "Low" indicates the lowest volume. Since the third character C is moving, the volume changes with the passage of time.

FIG. 3A is reproduction mode data in the case of reproducing the sound heard at the position of the first character A. FIG. 3B is reproduction mode data in the case of reproducing the sound heard at the position of the second character B. Comparing FIG. 3A and FIG. 3B, the volume level differs depending on which character's position the sound is heard. When the content reproduction device 1 reproduces the sound based on such reproduction mode data, the user can hear the sound of a different mode depending on the selected character, as shown in FIG.

FIG. 4 is a diagram showing another example of reproduction mode data corresponding to the moving image data shown in FIG. The reproduction mode data indicating the positional relationship between the characters may be data indicating information corresponding to the distance from one character to another character, as shown in FIGS. 4A and 4B. In FIGS. 4 (a) and 4 (b), the distance is shown in three stages of "large", "medium", and "small". FIG. 4A shows the distance from the first character A to the other character, and FIG. 4B shows the distance from the second character B to the other character. The content reproduction device 1 can enhance the sense of presence by reproducing the sound at a volume corresponding to the distance.

FIG. 5 is a diagram showing another example of reproduction mode data corresponding to the moving image data shown in FIG. In FIG. 5, the position of each character with the passage of time is shown. The coordinates (X, Y) represent the position X in the left-right direction and the position Y in the up-down direction with respect to the origin (0,0) at the upper left of the screen. Although the details will be described later, the content reproduction device 1 calculates the distance between the character and the sound source selected by the user based on the position of the character or the sound source indicated by the reproduction mode data, so that the character or the sound source can be generated. The mode of the sound when reproducing the emitted sound may be determined.

The storage unit 15 may temporarily store the moving image content received by the communication unit 11. Further, the storage unit 15 stores identification information for identifying the selected character when the operation reception unit 162 receives an operation for selecting a character. Further, the storage unit 15 stores the reproduction mode data included in the moving image content while the reproducing unit 163 reproduces the moving image content.

The control unit 16 has, for example, a CPU (Central Processing Unit). The control unit 16 functions as a content acquisition unit 161, an operation reception unit 162, and a reproduction unit 163 by executing the program stored in the storage unit 15.

The content acquisition unit 161 acquires content including sound data, reproduction mode data used for determining a plurality of reproduction modes of sound data, and moving image data. The content acquisition unit 161 may acquire these data at the same time, or may acquire each of them at different timings.

The operation reception unit 162 accepts a reproduction mode selection operation to be used for reproducing the sound data from a plurality of reproduction modes indicated by the reproduction mode data. The operation reception unit 162, for example, the operation reception unit 162 accepts an operation for setting at which position on the screen the sound to be heard is reproduced. The operation reception unit 162 displays, for example, a screen for selecting a reproduction mode, and selects a sound in a mode that can be heard at the position touched by the user while the screen is displayed as the reproduction mode.

The operation reception unit 162 may accept an operation of selecting one character from a plurality of characters included in the moving image content as a selection operation as a selection operation of the reproduction mode. As an example, the operation reception unit 162 accepts an operation of selecting a character desired by a user while a plurality of characters are displayed on the display 13. The operation reception unit 162 notifies the reproduction unit 163 of the selected reproduction mode.

The operation reception unit 162 may display information indicating a time zone in which the selection operation can be accepted while the playback unit 163 is playing the moving image content. In this case, when there are a plurality of time zones in which the operation reception unit 162 can accept the selection operation, the operation reception unit 162 may accept the selection of the reproduction mode for each of the plurality of time zones.

FIG. 7 is a diagram for explaining an operation of selecting a character. At the upper part of the screen shown in FIG. 7, a slide bar image G0 indicating that the displayable time zone of the moving image data is from 0 to 30:00, and a time zone in which the operation of selecting the sound reproduction mode can be accepted. The images G1 (G1a to G1d) showing the above and the images G2 showing the time during playback are displayed. The user can change the playback time by moving the position of the image G2.

An icon image M indicating the selected reproduction mode is displayed on the upper right of the screen. FIG. 7A shows a screen in which the sound heard at the position of the first character A is being reproduced. At the upper right of the screen shown in FIG. 7A, a mouse icon image M1 indicating that the sound heard at the position of the first character A is being reproduced is displayed.

While the screen of FIG. 7A is displayed, the operation reception unit 162 accepts an operation for switching to a state of reproducing the sound heard at the position of the second character B. As an example, the operation reception unit 162 identifies the selected character based on the direction of the swipe operation performed on the screen on which the moving image data being reproduced by the reproduction unit 163 is displayed.

The operation reception unit 162 is a method of reproducing the sound heard at the position of the second character B when the swipe operation is performed in the direction from the first character A to the second character B included in the moving image data, for example. Instruct the playback unit 163 to switch. The operation reception unit 162 instructs the reproduction unit 163 to switch to the method of reproducing the sound heard at the position of the second character B when the swipe operation is performed in the direction from the second character B to the first character A. You may. Further, the operation reception unit 162 reproduces a sound heard at the position of the first character A when the first character A is touched on the screen of FIG. 7A, and when the second character B is touched. , The reproduction unit 163 may be instructed to reproduce the sound heard at the position of the second character B.

FIG. 7B shows the screen after switching to the state in which the sound heard at the position of the second character B is being reproduced. At the upper right of the screen shown in FIG. 7B, a dog icon image M2 indicating that the sound heard at the position of the second character B is being reproduced is displayed.

When the operation reception unit 162 receives the operation of selecting a character, the operation reception unit 162 may store the identification information for identifying the selected character in the storage unit 15. The identification information stored in the storage unit 15 is referred to by the reproduction unit 163 when the user views the moving image content in which the same character appears in the future.

The reproduction unit 163 reproduces the moving image data and the sound data. The reproduction unit 163 creates screen data by reproducing the moving image data, and displays the moving image by inputting the created screen data to the display 13. Further, the reproduction unit 163 reproduces the sound data based on the reproduction mode selected by the user while reproducing the moving image data, and inputs the reproduced sound data to the speaker 12, so that the user desires it. The sound that can be heard at the desired position can be output from the speaker 12.

The reproduction unit 163 reproduces the sound data at a volume or sound quality corresponding to the positional relationship between the selected character and the place where the sound data is generated. That is, as described with reference to FIG. 2, the playback unit 163 outputs sound data at a lower volume as the distance from the selected character to the sound data generation location (for example, the position of another character or sound source) is longer. Reproduce. When an object that reverberates the sound exists between the selected character and the sound source, the reproduction unit 163 reproduces the sound data with an echoed sound quality as compared with the case where such an object does not exist. Good.

When there is an object (for example, a building) that reflects sound between the selected character and the sound source, the reproduction unit 163 generates the reflected sound at a timing delayed from the timing of reproducing the sound data that arrived without being reflected by the object. You may play it. In this way, the playback unit 163 changes the volume, sound quality, timing, etc. based on the positional relationship between the selected character and other characters or objects in each scene, so that the user can obtain a high sense of presence. it can.

The playback unit 163 changes from the volume heard at the position of the first character to the volume heard at the position of the second character, provided that the player swipes on the screen in the direction from the first character to the second character included in the video content. You may switch. By operating the playback unit 163 in this way, the user can easily hear the sounds heard at different character positions while watching the video content, so that one video content can be enjoyed in various ways. Can be done.

When the video content acquired by the content acquisition unit 161 includes a character whose identification information is stored in the storage unit 15, the reproduction unit 163 has a reproduction mode corresponding to the character (for example, at the position of the character). Sound data may be reproduced in an audible manner). When the content acquisition unit 161 acquires the video content, the playback unit 163 identifies the character included in the video content, for example, by referring to the meta information included in the video content. Then, the reproduction unit 163 confirms whether or not the storage unit 15 contains the identification information corresponding to the specified character. When the identification information is included, the reproduction unit 163 reproduces the sound data in the reproduction mode corresponding to the character corresponding to the identification information.

Specifically, it is assumed that the user has selected the sound corresponding to the first character A when viewing the video content in which the first character A appears in the past. In this case, it is considered that the user likes the first character A. Therefore, when the reproduction unit 163 reproduces another moving image content including the first character A, the reproduction unit 163 automatically selects and reproduces the sound corresponding to the first character A. By operating the reproduction unit 163 in this way, the user does not need to perform an operation for reproducing the sound corresponding to the first character A, which is suitable when the user's preference is fixed.

In the playback unit 163, identification information of a plurality of characters is stored in the storage unit 15, and the moving image content input from the content acquisition unit 161 includes a plurality of characters whose identification information is stored in the storage unit 15. If so, the operation reception unit 162 may be instructed to accept the selection of the character. In this case, the operation reception unit 162 displays a screen for accepting the character selection and accepts the character selection by the user.

Even when the identification information of a plurality of characters is stored in the storage unit 15, the playback unit 163 is used by the user within the latest predetermined period based on the date and time when the identification information is stored in the storage unit 15. Characters that are frequently selected may be selected. By operating the reproduction unit 163 in this way, even when the user is interested in a plurality of characters, it is possible to reproduce the sound that can be heard at the position of the character that is more likely to be preferred by the user.

[Process flow in content playback device 1]
FIG. 8 is a flowchart showing a processing flow in the content reproduction device 1. The flowchart shown in FIG. 8 starts from the time when the user of the content reproduction device 1 performs an operation of viewing the moving image content.

When the content acquisition unit 161 acquires the video content from the content distribution device 2 (S11), the operation reception unit 162 accepts an operation of selecting a character from the user and reproduces information for identifying the selected character 163. (S12). The reproduction unit 163 specifies the distance between the selected character and the sound source by referring to the reproduction mode data included in the moving image content (S13). The reproduction unit 163 determines the volume based on the specified distance (S14), and reproduces the sound data at the determined volume (S15).

While the reproduction unit 163 is reproducing the sound data and the moving image data, the operation reception unit 162 monitors whether or not an operation (for example, a swipe operation) for switching the character corresponding to the sound to be reproduced is performed (S16). When the operation reception unit 162 determines that the switching operation has been performed (YES in S16), the playback unit 163 returns the processing to S13, specifies the distance between the character and the sound source after the switching, and uses the new volume for sound data. Is reproduced (S13 to S15).

When the operation reception unit 162 does not determine that the switching operation has been performed in S16 (NO in S16), it is determined whether or not the operation to end the playback of the video content has been performed (S17), and from S15 until the end operation is performed. The process up to S17 is repeated.

[First modification]
In the above description, the case where the audio reproduction mode corresponding to the selected character is determined based on the distance between the character and the sound source has been illustrated, but the content reproduction device 1 has the volume determined in this way. Alternatively, the user may be able to adjust the sound quality and the like. In this case, the operation reception unit 162 accepts an operation for adjusting at least one of the volume and the sound quality included in the selected reproduction method. Then, the reproduction unit 163 reproduces the sound data at the volume or sound quality after being adjusted by the operation received by the operation reception unit 162.

As an example, the operation reception unit 162 displays an icon image on the display 13 for displaying a screen for adjusting the volume or sound quality to be played before the video content is being played or the video content is being played. Display it. When the icon image is selected, the operation reception unit 162 displays a screen for adjusting the volume, sound quality, or the like on the display 13.

The operation reception unit 162 may accept adjustment of volume or sound quality for each character appearing in the moving image content. The operation reception unit 162 may accept adjustment of the volume or sound quality of the character appearing in the time zone in which the operation of selecting the sound reproduction mode shown in FIG. 7 is accepted. By accepting the operation of adjusting the sound reproduction mode in this way, the operation reception unit 162 allows the user to listen to the sound in a preferred mode, so that a higher sense of presence can be obtained.

[Second modification]
In the above description, the case where the video content includes the reproduction mode data indicating the volume, sound quality, timing, etc. when the sound data is reproduced has been illustrated, but the reproduction mode data corresponds to each character. It may be sound data (for example, a file containing sound data). For example, when the video content includes the first character and the second character, the video content is composed of standard sound data and sound data corresponding to the sound heard at the position of the first character. The reproduction mode data and the second reproduction mode data composed of the sound data corresponding to the sound heard at the position of the second character may be included. The video content may include a number of sound data corresponding to the number of characters.

The first reproduction mode data includes sound data emitted by each sound source corresponding to the volume as shown in FIG. 3A, for example. The second reproduction mode data includes sound data emitted by each sound source corresponding to the volume as shown in FIG. 3B, for example. In this case, the reproduction unit 163 reproduces the sound data included in the reproduction mode data corresponding to the character selected by the user. Since the reproduction mode data is configured in this way, the reproduction unit 163 does not need to create the sound data in which the mode of the sound at the time of reproduction is adjusted, so that the generation of processing delay in the reproduction unit 163 can be prevented. Can be done.

[Third variant]
The content reproduction device 1 may be configured so that the quality of the reproduced sound can be further switched. The content playback device 1 receives from the user a selection operation for reproducing with stereophonic sound (also referred to as three-dimensional sound or three-dimensional audio) that allows the direction of the sound source and the distance to the sound source to be felt, and performs the selection operation. Sound of the corresponding quality may be reproduced. In this case, the content reproduction device 1 may operate so as not to charge the user when reproducing the standard sound, but to charge the user when reproducing a sound other than the standard sound. The control unit 16 of the content reproduction device 1 acquires sound data to be reproduced from the content distribution device 2 by transmitting user identification information to the content distribution device 2, for example, when the user selects a sound other than the standard sound. .. The content distribution device 2 stores the billing amount in association with the user identification information, and bills the user at a predetermined timing. By operating the content playback device 1 and the content distribution device 2 in this way, it is possible to provide a high-quality sound to the user.
