JP 2002-14683 A

However, in the conventional technology described above, there is room to improve the interest of using applications used for content playback, etc.

One aspect of the present invention was made in consideration of the above problems, and aims to improve the enjoyment of using applications used for content playback, etc.

In order to solve the above problem, a display device according to one aspect of the present invention is a display device having a display unit, and includes an input unit for inputting an identification code associated with content into an input screen for the identification code, and a control unit for outputting at least one of an image and sound associated with the content on at least one of the input screen and a start-up screen for an application for playing the content when authentication is performed using the input identification code and the content becomes available on the display device.

To solve the above problem, a server device according to one aspect of the present invention includes an acquisition unit that acquires an identification code associated with the content and information that identifies the display device that transmitted the identification code and the screen size of the display device, and a communication unit that transmits an image associated with the content, the image corresponding to the screen size of the display device, to the display device after authentication using the identification code is performed, so that the image can be displayed on an application installed on the display device and used to play the content.

The display device and server device according to each aspect of the present invention may be realized by a computer. In this case, the control program that causes the computer to operate as each unit (software element) of the display device or server device to realize the display device or server device on the computer, and the computer-readable recording medium on which the control program is recorded, also fall within the scope of the present invention.

According to one aspect of the present invention, it is possible to increase the interest of using an application used for playing content, etc.

FIG. 2 is a block diagram illustrating an example of a functional configuration of the system. 13 is an example of a table stored in a storage unit of the server device. FIG. 11 is an example of a sequence diagram illustrating a process flow according to an example of the system processing. 13 is an example of an input screen for an identification code and a list screen for contents in an application. 13 is an example of an application start screen. 11A to 11C are diagrams illustrating an example of a procedure by which a user selects and sets an image to be output on an input screen.

One embodiment of the present invention is described in detail below.

[1. Example of system 1 configuration]
1 is an example of a block diagram showing a functional configuration of a system 1 according to the present disclosure. The system 1 is a system for transmitting video included in any content from a server device 10 to a display device (external device) 20 and playing the video. In many cases, one or more channels of audio (music) included in the content are associated with the video, and the audio is played in parallel with the video on the display device 20.

The system 1 includes a server device 10 and one or more display devices 20. The server device 10 functions as a server that supplies content, and includes a control unit 11, a storage unit 12, and a communication unit 13.

The control unit 11 is a control device that controls the entire server device 10, and includes an acquisition unit 111. The acquisition unit 111 acquires an identification code associated with the content, and information that identifies the display device 20 that is the sender of the identification code. In this disclosure, the content that includes the above-mentioned video is also simply referred to as "video content." However, it is not essential that the content includes video, and it may be configured to include only audio. In addition, the content is associated with one or both of another image and audio that are output on the startup screen of the application described below, etc., in addition to the main content of video or audio.

The identification code is a serial code (serial number) including alphanumeric characters and symbols for identifying the content. The identification code may be sold for a fee or provided free of charge. As will be described in detail later, a single identification code may be associated with multiple pieces of content. This means that a user can download multiple pieces of content by inputting a single identification code into the display device 20. A single piece of content may also be associated with multiple types of identification codes.

The memory unit 12 is a storage device that stores various information, for example, a table showing the correspondence between content and identification codes. The control unit 11 refers to the table and performs authentication using the identification code acquired by the acquisition unit 111. From another perspective, authentication is a process of determining whether the identification code acquired by the acquisition unit 111 is legitimate.

The communication unit 13 is an interface that performs communication processing with the display device 20 and the like based on the control of the control unit 11. For example, the communication unit 13 transmits video content to the display device 20. The communication unit 13 may transmit the video to the display device 20 by streaming transmission, or may transmit the video all at once so that it is stored as chunk data in the display device 20. Streaming reception in the display device 20 is a type of download. Note that even when the display device 20 plays back video stored in the storage unit 22 and streaming reception does not occur, authentication using an identification code is performed before the video is played back.

It is also desirable that the video and other data transmitted between the server device 10 and the display device 20 be encrypted before transmission and then decrypted on the receiving device.

The display device 20 is a device capable of outputting video and audio, and can be realized as, for example, a smartphone, a tablet, a personal computer, a television, or a game console. The display device 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, and a display unit 25.

The control unit 21 is a control device that controls the entire display device 20, and includes a display control unit 211. The display control unit 211 controls the screen display on the display unit 25. The display control unit 211 causes the display unit 25 to display an image input to the display device 20 from, for example, the server device 10. An application for playing images and audio is also installed on the display device 20, and the identification code is input on an input screen displayed by the display control unit 211 on the application. The display control unit 211 also performs processing to display a start-up screen when the application is started.

The storage unit 22 is a storage device that stores various types of information, for example, an already authenticated identification code and information that identifies the content associated with the identification code. Here, the information that identifies the content may be, for example, the ID of the content or an identification code associated with the content. The storage unit 22 also stores application data for playing video and audio.

The communication unit 23 is an interface that performs communication processing with the server device 10 and the like based on the control of the control unit 21. For example, the communication unit 23 transmits information that identifies the content selected by the user via the input unit 24 to the server device 10.

The input unit 24 is a member through which the user inputs information to the display device 20, and may be realized as, for example, a keyboard or other buttons, or a mouse. The input unit 24 may also be a remote control or controller that is separate from the display device 20 itself. The user inputs an identification code and performs various selection operations via the input unit 24. The input unit 24 and the display unit 25 may also be realized as an integrated touch panel.

As shown in FIG. 1, the input unit 24 may also include a camera 241 that captures an image. The input unit 24 may also be configured to be able to read a two-dimensional code indicating an identification code using the camera 241. This can reduce the effort required for the user to input the identification code.

The display unit 25 is a display panel that displays images, character strings, objects, etc. based on the control of the display control unit 211.

The function of a single component included in system 1 may be realized by multiple other components, and the functions of multiple components included in system 1 may be realized by a single other component. For example, system 1 may include multiple server devices 10, and the authentication of the above-mentioned identification code may be performed by an authentication device other than the server device 10. In addition, some of the components included in system 1 may be detachable from the server device 10 or the display device 20.

[2. Example of authentication table]
Next, a specific example will be described of the above-mentioned table stored in the storage unit 12 of the server device 10. Table 31 in Fig. 2 is an example of a table showing the correspondence between contents and identification codes.

For example, Table 31 shows that video content A includes video from channels A1 to A3, and video content B includes video from channels B1 to B3. The value in the "Identification Code" column indicates which identification code is required for authentication in order to download the video of the corresponding channel to the display device 20. For example, in order to download the video of channel A3 to the display device 20, authentication using identification code "AAABBB222" or "AAABBB333" is required, and even if authentication using identification code "AAABBB111" is performed, the video of channel A3 cannot be downloaded.

In addition, content may be associated with multiple types of identification codes and may include video of one or multiple channels defined for each type of identification code. In the display device 20, the user can select and play video of any channel. For example, video content A is associated with a first type of identification code that allows only video of channels A1 and A2 to be downloaded, and a second type of identification code that allows video of channels A1 to A3 to be downloaded.

A single identification code may be associated with multiple contents, and at least some of the multiple contents may include video of multiple channels. For example, when authentication is performed using the identification code "AAABBB333", video content A and video content B can be downloaded on the display device 20 that is the source of the identification code. Note that it is desirable for the actual identification code to be a more complex character string than the example shown in FIG. 2.

The video of each channel included in a certain content may be the same, or may be the same content with only the video format or bit rate differing, or the content may be different from each other. When at least the video of each channel is the same, the content of the audio associated with each video, or the audio format or bit rate of the audio, is usually different from each other. In one aspect, at least any two of the videos of each channel included in a certain content may be different from each other, and the audio associated with the two videos may be different from each other.

In one aspect, among the video of each channel included in a certain content, the video of at least any two channels may be video of a specific subject, part or all of which is shot from different positions, and may be associated with audio corresponding to each shooting position. Here, the audio corresponding to the shooting position is, for example, audio collected at the shooting position, or audio that reproduces the collected audio. The audio corresponding to the shooting position may be immersive audio such as Dolby Atmos (registered trademark), Auro-3D (registered trademark), 360 Reality Audio (registered trademark), or spatial audio.

For example, if the content is a live video of a singer, it is possible to reproduce the video as seen from different seating positions and the audio heard at those positions for each channel. Also, for example, the video on one channel may be a video of the entire singer group as the entire subject, and the video on another channel may be a video of one member of the singer group as part of the subject.

In one embodiment, the selling price of an identification code for enabling playback of the video of a channel when viewed from a seating position close to the singer who is the subject of the video may be higher than the selling price of an identification code for enabling playback of only the video of the channel when viewed from a seating position farther away.

Table 32 is an example of a table showing the correspondence between an identification code and a display device 20 that has been registered by authentication using that identification code.

In Table 32, the denominator of the value in the "Number of registered devices" column indicates the maximum number of display devices 20 that can be registered by authentication using the corresponding identification code. Furthermore, "registering" a display device 20 means storing the display device 20 that sent the identification code as a display device 20 that can download content associated with that identification code. Furthermore, as indicated by the fact that the denominator may be 2 or more, a single identification code may be input to each of multiple display devices 20, allowing content to be downloaded to each of the display devices 20.

The numerator of the value in the "Number of registered devices" column indicates how many display devices 20 are currently registered through authentication using the target identification code. For example, in the case of the identification code "AAABBB111," the maximum number of three display devices 20 are already registered, so even if the identification code "AAABBB111" is entered into a new display device 20, that display device 20 will not be registered. It is also desirable that the display device 20 be configured to be unregistered by operating the input unit 24 of the display device 20, for example. This makes it possible to switch display devices 20 from which content can be downloaded, even if the number of devices that can be registered using a certain identification code has been reached.

The value in the "Registered display device" column is a value such as a MAC address that uniquely identifies an individual display device 20, and indicates a display device 20 that has been registered through authentication using the corresponding identification code.

In this way, the storage unit 12 of the server device 10 stores one or more authenticated identification codes in association with information identifying one or more display devices 20. Furthermore, when the acquisition unit 111 acquires information identifying the display device 20, an authentication process is performed using an identification code stored in the storage unit 12 that is associated with the information identifying the display device 20. Here, the authentication process may include, for example, authentication by the server device 10 alone, or authentication using another authentication device as described above.

The identification code may have an expiration date. In the above configuration, the storage unit 12 stores the expiration date of the identification code in association with the identification code. For example, the expiration date may be determined based on the period from when the identification code is first used for authentication, or the date and time when the identification code will no longer be valid may be determined in advance. For a single identification code, different expiration dates may be set for each piece of content, or for each channel. If the content is real-time live video or recorded live video, the identification code may be valid only during live streaming.

[3. Processing example of System 1]
Next, an example of the flow of processing executed by the system 1 will be described. In this example, the input of the above-mentioned identification code and the playback of video and audio, which will be described later, will be described as being performed using an application installed on the display device 20. Fig. 3 is an example of a sequence diagram showing the flow of processing according to this example.

In S101 (step S101), the display control unit 211 of the display device 20 causes the display unit 25 to display an input screen for the identification code.

Screen 51 in FIG. 4 is a screen of the application, and shows an example of an input screen for an identification code. Note that in this example of screen 51, no image associated with the content is displayed. In screen 51, input forms 52 and 53 are input forms for inputting an identification code.

In the example of screen 51, the content is a video of an event such as a live performance, and input form 52 is a form for inputting a character string that identifies the event. The "event code" input into input form 52 may be a common value for each event. Furthermore, input form 53 is a form for inputting "serial codes" that are different for each event.

As exemplified in input forms 52 and 53, a single identification code may be configured to include two or more character strings, or, for example, of the aforementioned "event code" and "serial code," only the "serial code" may be treated as the identification code.

In addition, according to the configuration of the present disclosure, as shown in screen 51, when a user downloads content, he or she is not necessarily required to enter personal information or register as a member.

In S102, the control unit 21 acquires the identification code input by the user via the input unit 24.

In S103, the control unit 21 transmits the input identification code and information identifying the own device to the server device 10 via the communication unit 23. The information identifying the own device includes information identifying the screen size of the display unit 25 in the display device 20. Information identifying the model of the display device 20 may be used as the information identifying the screen size. In the example of screen 51, the process of this step S103 is executed when button 54 is pressed.

In S104, the acquisition unit 111 of the server device 10 acquires each piece of information received via the communication unit 13, and the control unit 11 performs authentication using the identification code. If the authentication is successful, the process of S105 is then executed. Furthermore, the control unit 11 associates the display device 20 that is the source of the identification code with the identification code and registers it in the storage unit 12 as a "registered display device" as exemplified in Table 32 of FIG. 2.

In S105, the control unit 11 transmits to the display device 20 the video and audio of the content associated with the identification code used for authentication. In addition, when there are multiple videos of the content associated with the identification code used for authentication or the channels included in the content, the video of the channel to be transmitted first as a default may be specified. In addition, the control unit 11 transmits the image and audio associated with the content to the display device 20. The image and audio are stored in the storage unit 22 of the display device 20. In addition, the image associated with the content may be an image according to the screen size of the display device 20. For example, when the display device 20 is a personal computer, the control unit 11 may transmit a landscape image to the display device 20, and when the display device 20 is a smartphone, the control unit 11 may transmit a portrait image to the display device 20. In addition, the image may be a GIF image in which part or all of the image moves.

If the authentication using the identification code is unsuccessful, the control unit 11 transmits information indicating that the authentication was unsuccessful to the display device 20 without transmitting video and audio. Here, cases in which the authentication using the identification code is unsuccessful include cases in which the identification code is incorrect or the number of registered devices has reached the upper limit.

In S106, the display control unit 211 of the display device 20 performs processing to display the image of the content received by the communication unit 23 on the display unit 25. That is, when authentication using the identification code is performed, the display control unit 211 displays the image included in the content transmitted from the server device 10 on the display unit 25. Additionally, the control unit 21 plays back the audio included in the content. Furthermore, the control unit 21 stores information identifying the content associated with the identification code for which authentication was successful in the storage unit 22.

In S107, the display control unit 211 ends the process of displaying the content video on the display unit 25 when the content video has been played to the end or in response to a user operation. Then, the control unit 21 ends the application for playing the video and audio in response to the user operation.

In S108, the control unit 21 starts the application in response to a user operation. The display control unit 211 also displays a start-up screen while the application is running. The control unit 21 also outputs at least one of an image and a sound associated with the content on the start-up screen.

Screen 60 in FIG. 5 shows an example of a start-up screen displayed on display unit 25 in step S108. In screen 60, an image associated with the content is displayed on the entire screen as a start-up screen. Here, person 61 included in screen 60 is a performer who appears in the video content. Also, the line "Hello!" written in speech bubble 62 indicates a line output in the voice of person 61 by control unit 21 from a speaker of display device 20 (not shown). In a broad sense, the image or sound associated with the content output on the start-up screen or on the input screen for the identification code as described later may be an image or sound of a singer or performer of the content, or an actor or character who appears in the content. This can further increase the interest of using the application by displaying an image of a singer that the user likes, and encourage the playback of the content.

The text 63 included in the screen 60 includes the expiration date set in the identification code of the content. In a broader sense, the control unit 21 may output an image or sound including information about the expiration date to at least one of the start-up screen and the identification code input screen. This helps the user recognize the expiration date until which the content can be played.

In order to increase rarity, it is desirable that the image or sound associated with the content can be output only on a dedicated application used to play the content. For example, the above-mentioned configuration is realized by storing the image or sound associated with the content in the storage unit 22 as data used in the application. From another perspective, the communication unit 13 of the server device 10 may be configured to transmit the image or sound associated with the content to the display device 20 after authentication using the identification code is performed so that the image or sound can be output only on an application installed on the display device 20 that is used to play the content.

In addition, it is not essential that the control unit 21 performs a process of temporarily terminating the application after the display control unit 211 has ended the process of displaying the content image on the display unit 25 in S107, and the process of S109 may be executed following the end of the process of displaying the image on the display unit 25.

In S109, the display control unit 211 causes the display unit 25 to display an input screen for an identification code. The control unit 21 also causes at least one of an image and a sound associated with the content to be output on the input screen for the identification code. Screen 64 in FIG. 5 shows an example of an input screen displayed on the display unit 25 in this step S109. Screen 64 includes people 65a to 65d who are performers appearing in the video content. Images of people 65a to 65d are displayed as wallpaper on screen 64, and the aforementioned input form 52 and the like are also included on the screen.

The control unit 21 may also output lines from the speaker of the display device 20 in the voice of one of the characters 65a to 65d on the screen 64, or may include information regarding the expiration date on the screen 64. When an identification code is entered on the screen 64, the process from S102 is repeated for that identification code.

Note that it is not essential that images associated with the content are displayed on the start-up screen and input screen, and the configuration may be such that only audio associated with the content is output.

The control unit 21 may also be configured to output an image or sound associated with the content only on either the start-up screen or the input screen.

As described above, the control unit 21 according to this embodiment performs a process to output at least one of an image and sound associated with the content on at least one of the start-up screen and the input screen when authentication is performed using the input identification code and the content becomes available on the display device 20.

The above describes the process flow based on the sequence diagram in Figure 3. The configuration of this example can improve the interest of using applications used for content playback, etc.

[4. Additional Notes]
The configuration is not limited to one in which the images and audio associated with the content are stored in the memory unit 22 of the display device 20 in S105, but may be one in which the images and audio are obtained from the server device 10 using an API or the like immediately before the display device 20 outputs the images and audio, or one in which authentication by the server device 10 is required at regular intervals.

In addition, instead of the processes of S101 and S102, the display control unit 211 may display a list of contents associated with the authenticated identification code on the display unit 25, and the control unit 21 may identify the content selected from the contents included in the list via the input unit 24. In this case, in S103, the communication unit 23 transmits information identifying the display device 20, which is the device itself, and information identifying the selected content to the server device 10. In addition, in S104, the control unit 11 of the server device 10 authenticates that the identified display device 20 is registered using the identification code associated with the selected content. With the above configuration, it is not necessary to re-input an identification code that has been successfully authenticated once into the input unit 24, reducing the user's effort.

Screen 56 in FIG. 4 is a screen of the aforementioned application, and shows an example of a list screen of contents associated with an authenticated identification code. The screen may be configured to allow direct specification of the channel to be played first, as exemplified by button 57.

In addition, the video of each channel may be configured to have multiple chapters set at regular or arbitrary time intervals, and the playback position may be made to jump to the beginning of a chapter selected by the user from the list. This is true not only when the display device 20 downloads and stores the video, but also when the video is received via streaming. The above configuration is realized when the control unit 11 of the server device 10 transmits information indicating a list of chapters stored in the storage unit 12 to the display device 20, and the control unit 21 of the display device 20 reads out the video of the chapter selected by the user from the storage unit 22 or receives the video via streaming from the server device 10.

The image or sound output on the start-up screen and input screen may correspond to the most recently authenticated identification code, i.e., may be an image or sound associated with the content associated with the most recently authenticated identification code. Alternatively, an image or sound corresponding to any already authenticated identification code may be output randomly, for each day of the week, or on a daily basis, etc. Furthermore, an image or sound associated with the most recently played content or frequently played content on the display device 20 may be displayed on the start-up screen and input screen.

The configuration may also be such that the user can select an image or sound to be output on the startup screen or input screen from among images or sounds corresponding to any of the already authenticated identification codes. In the above configuration, when authentication is performed using one or more identification codes and there are multiple images or sounds that can be output, the control unit 21 performs processing to output one or more images or sounds specified by a user operation on the input unit to at least one of the startup screen and the input screen. This makes it possible to output the image or sound desired by the user to the startup screen and the input screen.

Figure 6 shows an example of a procedure in which a user selects and sets an image to be output on the input screen. Screen 64 is an example of an application setting screen. When "change wallpaper" is selected on screen 64, a transition is made to screen 65 for selecting the wallpaper of the input screen. Images 69a to 69d on screen 65 are images associated with a single content. When image 69a is selected here, a transition is made to screen 66 for setting the display size and display position of image 69a. Frame 70 included in screen 66 is a guide used to change the display size and display position of the image. When display device 20 is a smartphone, a configuration is preferable in which the display size is changed by a pinch operation on the image, and the display position is changed by a drag operation on the image. Screen 67 shows an input screen reflecting the display size and display position of the image determined on screen 66.

In addition, when multiple types of identification codes are associated with the content, the images and sounds that can be output on the start-up screen or the input screen and the number of them may correspond to the type of identification code. In this configuration, the control unit 21 performs a process of outputting an image or sound corresponding to the type of identification code to at least one of the start-up screen and the input screen. This provides a wide variety of images and sounds to be output on the start-up screen or the input screen, which contributes to improving user satisfaction as a content benefit. For example, the control unit 11 of the server device 10 may perform a process of transmitting a first image to the display device 20 and not transmitting a second image when a first type of identification code is authenticated, and transmitting a second image to the display device 20 and not transmitting the first image when a second type of identification code is authenticated. In addition, the control unit 21 may output an image or sound including information indicating the type of identification code or information corresponding to the type of identification code to at least one of the start-up screen and the input screen.

In addition, the images and sounds that can be output on the display device 20 by authenticating the identification code may be a portion randomly selected by the control unit 11 of the server device 10 from a group of images and sounds stored in the memory unit 12. From another perspective, the user may be able to use content by inputting the identification code into an input screen, and may also be able to randomly obtain images or sounds associated with the content as a so-called "gacha." Furthermore, the probability of obtaining each of the images or sounds available as "gacha" may depend on the type of identification code.

If an authenticated identification code does not exist, for example, a start-up screen including only the application logo or the input screen shown in screen 51 of FIG. 4 is displayed. That is, for example, when an application is started before the processing of S101 of FIG. 3, a start-up screen including only the application logo may be displayed. Even if an authenticated identification code exists, it is desirable to have a configuration that allows a setting screen, for example, shown in screen 64 of FIG. 6, to be set so that images or sounds associated with the content are not output to the start-up screen and input screen.

In addition, when the identification code has expired, the image and sound corresponding to the identification code may not be output on the display device 20. In other words, the control unit 21 may be configured to stop output of the image or sound associated with the content when authentication using the identification code is cancelled and the content cannot be used on the display device 20. This helps the user to recognize that the identification code has expired.

The skin of the content list screen exemplified in screen 56 and the setting screen exemplified in screen 64 may be changeable to a skin corresponding to the authenticated identification code. In other words, the control unit 21 may be configured to change the skin of the application operation screen to a skin associated with the content when the content becomes available on the display device 20. This can further increase the interest of using the application used for playing the content. The skin associated with the content is, for example, a skin that gives the setting screen the same color scheme as the characters appearing in the content. The above configuration is realized by the control unit 11 of the server device 10 transmitting information indicating the skin to the display device 20 in S105. The aspect of the system 1 related to the skin is similar to the explanation given for the image or sound associated with the content.

[4. Software implementation example]
The functions of the server device 10 and the display device 20 (hereinafter referred to as the "devices") can be realized by a program for causing a computer to function as the device, and a program for causing a computer to function as each control block of the device (particularly the control unit 11 and each unit included in the control unit 21).
