As an example, the content which is executable by the first display apparatus 100 and the second display apparatus 200 may include content which by a general user without expertise, such as, for example, storytelling content, and/or the like.
The storytelling content refers to content about a story which is generated by a content provider using various image objects and non-image objects and is provided to a different user who wants to view the content. The non-image objects collectively refer to objects which are not an image, such as a text, a sound, and/or the like.
According to various embodiments of the present disclosure, the objects from which a story is generated may form a scene. The storytelling content may include a single scene, or may include a plurality of scenes which is sequentially arranged.
FIG. 3 illustrates an example of a scene of storytelling content displayed in a first display apparatus or a second display apparatus according to an embodiment of the present disclosure.
Referring to FIG. 3, a scene 300 of the storytelling content includes a background object 310 as an image which forms the background of the scene 300, an inserted image object 320 as an image which may be overlaid on the background object 310. The scene 300 may also include an additional object 330 which may be added to the background object 310 and/or the inserted image object 320. For example, the additional object 330 may be added in order to explain the content and/or context of the scene 300.
According to various embodiments of the present disclosure, the background object 310 may employ various images such as a landscape (e.g., a city, a country, a mountain, a river, a field, a sky, a sea, a space, and/or the like) as the background of the scene 300. When a user views the scene 300, the background object 310 is disposed in back of the inserted image object 320 so that the inserted image object 320 is disposed on the front side.
The inserted image object 320 collectively refers to images which are overlaid on the background object 310, such as a human, animal, thing, and/or the like. For example, if the scene 300 is a scene in which a person stands on a field, the field may correspond to the background object 310, and the person may correspond to the inserted image object 320. Further, if the scene 300 is a scene in which an airplane is flying in the sky, the sky may correspond to the background object 310, and the airplane may correspond to the inserted image object 320.
However, in the scene 300 which is formed by only the background object 310 and the inserted image object 320, because there is no explanation, what intent or meaning the scene 300 has may be ambiguous (e.g., to a user viewing the screen). The additional object 330 has the function of directly showing the intent or meaning of the scene 300 (e.g., the additional object 330 may provide context for the scene). For example, the additional object 330 may supplement the scene 330 with a story thereof to a viewer of the scene 300. The division (e.g., and arrangement) of the inserted image object 320 and the additional object 330 may vary according to design as a matter of convenience.
For example, the additional object 330 may be a non-image object such as a text, sound, and/or the like. As another example, the additional object 330 may be an image. According to various embodiments of the present disclosure, the additional object 330 may be a combination of non-image objects and image objects. If the inserted image object 320 is a human or a personified being, the additional object 330 may be a text in a speech balloon or audio data for expression of a speech of the inserted image object 320.
According to various embodiments of the present disclosure, the respective objects (e.g., background object 310, inserted image object 320, additional object, and/or the like) may be used (e.g., configured, arranged, and/or the like) to convey a story of the scene 300. For example, a user may understand the story of the scene 300 through the respective objects (e.g., background object 310, inserted image object 320 and additional object 330) which form the scene 300.
If the storytelling content includes the plurality of scenes 300 and the respective scenes 300 are sequentially executed and displayed in a temporal order, the user may understand a long and complicated story like a movie or drama from the content.
This storytelling content may not be generated only by a special content provider with special equipment or skill, but may also be generated by a general user as the first display apparatus 100 or the second display apparatus 200 provides a User Interface (UI) environment to execute an application program for content generation.
Hereinafter, the UI environment with which the user may generate the storytelling content through the second display apparatus 200 as the mobile device will be described.
FIG. 4 illustrates an example of a UI displayed in a second display apparatus to allow a user to generate storytelling content according to an embodiment of the present disclosure.
According to various embodiments of the present disclosure, the second storage section 240 of the second display apparatus 200 stores an application program and data for generation of the storytelling content. If the second controller 250 executes the application program, a content generation UI 400 is displayed in the second display section 220, as illustrated in FIG. 4.
Referring to FIG. 4, the UI 400 includes a background image menu 410, an inserted image menu 420, an additional option menu 430, a scene formation area 440, and the like. The background image menu 410 may display a plurality of background objects 411 that are stored in advance and that are provided by the application program. The inserted image menu 420 may display a plurality of inserted image objects 421 that are stored in advance and that are provided by the application program. The additional option menu 430 may provide options for formation of an additional object. The scene formation area 440 corresponds to an area in which a scene of storytelling content is formed by various objects selected from the respective menus (e.g., the background image menu 410, the inserted image menu 420, and additional option menu 430).
The arrangement of the respective menus (e.g., the background image menu 410, the inserted image menu 420, and additional option menu 430) and the scene formation area 440 is an example, and thus, may be variously changed according to design and/or preferences (e.g., user preferences and/or the like).
The background objects 411 and the inserted image objects 421 respectively displayed in the background image menu 410 and the inserted image menu 420 may be realized as thumb-nail images so that the user can easily confirm their original content.
A method of generating a scene of the storytelling content through the UI 400 by the user will be described as follows.
According to various embodiments of the present disclosure, the user selects and determines the background object 411 for formation of the background of the scene from the background image menu 410. If the second display section 220 is realized (e.g., configured) as a touch-screen, the user may drag the background object 411 selected from the background image menu 410 and may drop the selected background object 411 into the scene formation area 440, to thereby perform the object selection and determination. This method is an example, and thus, various methods may be used to select and determine the object.
According to the selection and determination of the background object 411, the second controller 250 displays an image of the corresponding background object 411 in the scene formation area 440.
The user selects and determines the inserted image object 421 from the inserted image menu 420. In a similar manner to the example of selecting a the background object 411, the user may drag the inserted image object 421 selected from the inserted image menu 420 and may drop the selected inserted image object 421 at a desired location in the scene formation area 440. Thereafter, the second controller 250 displays the corresponding inserted image object 421 to be overlaid on the background object 411, in the scene formation area 440. The second controller 250 may display the inserted image object 421 at the location at which the selected inserted image object 421 is dropped.
In this manner, the user may form a scene based on the background object 411 and the inserted image object 421 in the scene formation area 440.
Thereafter, the user may select and determine an option provided by the additional option menu 430 to add an additional object for explanation of a story of the formed scene to the scene.
According to various embodiments of the present disclosure, the options of the additional objects provided by the additional option menu 430 may be determined in various forms, which may include “sound recording”, “text input”, “image”, “scene formation,” and/or the like. The names of these options are given for convenience's sake, and thus, do not limit the scope of the present disclosure.
For example, if “sound recording” is selected, the user may input the user's voice or a variety of sound through the microphone (not shown) of the second display apparatus 200. The second controller 250 adds audio data on the input voice or sound to data on the scene currently formed in the scene formation area 440. The added audio data is executed, when the corresponding scene is executed and displayed later in the first display apparatus 100 or the second display apparatus 200, together with the scene.
If “text input” is selected, the second controller 250 provides a character input interface such as an image keyboard (not shown) so that the user can input a predetermined text at a specific position of the scene formed in the scene formation area 440. The second controller 250 adds the input text to the data on the corresponding scene.
If “image” is selected, the second controller 250 provides a separate application program or tool from which the user may generate a new image, or provides an interface through which the user may call an image stored in the second display apparatus 200 or various devices on the network. The second controller 250 inserts the image selected in this manner into the scene formed in the scene formation area 440.
If “scene formation” is selected, the second controller 250 provides an interface through which the user may combine the plurality of scenes generated as described above and currently stored in the second storage section 240 in a desired order. The second controller 250 generates storytelling content using the plurality of scenes combined in this manner.
According to the above-described method, the user may generate the storytelling content through the UI 400 provided by the second display apparatus 200. The second display apparatus 200 may store the generated storytelling content in the second storage section 240, may transmit the storytelling content to the first display apparatus 100 so that the first display apparatus 100 can store and execute the storytelling content, or may transmit the storytelling content to a content server (not shown) on the network.
However, the storytelling content generation environment of the second display apparatus 200 provided in this manner may cause the following inconvenience to the user.
If the second display apparatus 200 is a mobile device, the user may form a scene of storytelling content in the scene formation area 440 using the drag-and-drop method. However, because the size of the second display section 220 may be small in view of characteristics of the mobile device, the user may not easily view the scene displayed in the scene formation area 440.
In consideration of this problem, according to the present embodiment, the following method is proposed.
FIG. 5 illustrates an example of an image displayed in a first display apparatus while a content scene is being generated in a second display apparatus according to an embodiment of the present disclosure.
Referring to FIG. 5, the user generates one scene of the storytelling content through a UI displayed in the second display apparatus 200. This UI is approximately the same as in the embodiment illustrated in FIG. 4, and detailed description thereof will be omitted.
While one scene of the storytelling content is being generated through the UI displayed in the second display apparatus 200, the second controller 250 of the second display apparatus 200 performs a control so that the same image 520 as the scene displayed in a scene formation area 510 of the UI is displayed in the first display apparatus 100. For example, while the storytelling content is being generated in the second display apparatus 200, the first display apparatus 100 displays the same image 520 as the image 510 of the storytelling content generated in the second display apparatus 200 in real time.
If the first display apparatus 100 is a television, because the first display apparatus 100 has a display screen larger than that of the second display apparatus 200, the user may clearly confirm the image 510 of the scene of the storytelling content generated in the second display apparatus 200 as the large image 520 in the first display apparatus 100. According to various embodiments of the present disclosure, because the user generates the storytelling content in the second display apparatus 200, easily generating the storytelling content is possible compared with a case in which the storytelling content is generated in the first display apparatus 100.
In order to display the same image 520 as the scene formation area 510 in the first display apparatus 100 while the scene is being generated in the scene formation area 440 of the second display apparatus 200, the following configuration may applied between the first display apparatus 100 and the second display apparatus 200.
FIG. 6 illustrates a UI which provides selection of devices which are accessible by a second display apparatus for communication according to an embodiment of the present disclosure.
Referring to FIG. 6, the second display apparatus 200 may display a UI 610 which indicates various devices which are currently accessible by the second display apparatus 200 for communication. The user may click a desired device from among the devices displayed in the UI 610 to designate a communication connection between the selected device and the second display apparatus 200. For example, the device selected in the UI 610 serves as the first display apparatus 100 in the above-described embodiment.
The communication connection between the first display apparatus 100 and the second display apparatus 200 may be performed by various techniques, which does not limit the scope of the present disclosure. For example, the first display apparatus 100 and the second display apparatus 200 may be connected to each other for communication on the basis of a network technique which supports a Universal Plug and Play (UPnP) function based on Transmission Control Protocol/Internet Protocol (TCP/IP), and/or the like.
FIG. 7 is a block diagram illustrating a configuration of a data transmission relationship between a first display apparatus and a second display apparatus according to an embodiment of the present disclosure.
Referring to FIG. 7, the second storage section 240 of the second display apparatus 200 stores a background object 710 and an inserted image object 720 for generation of a scene of storytelling content. The second controller 250 may provide the background object 710 and the inserted image object 720 stored in the second storage section 240 in generation of the storytelling content, and the user may select the background object 710 and the inserted image object 720 to form a scene, similarly to the above-described various embodiments of the present disclosure.
The first storage section 140 of the first display apparatus 100 may also store a background object 711 and an inserted image object 721. The background object 711 and the inserted image object 721 stored in the first storage section 140 have the same data as in the background object 710 and the inserted image object 720 stored in the second storage section 240.
According to various embodiments of the present disclosure, such a configuration may be achieved by installing an application program for generation of the storytelling content in the second display apparatus 200 and by installing an application program corresponding to the application program of the second display apparatus 200 in the first display apparatus 100. As the application programs for generation of the storytelling content are respectively installed in the first display apparatus 100 and the second display apparatus 200, a communication channel for transmission of data or information relating to content generation may be built.
According to various embodiments of the present disclosure, if the user selects a predetermined background object 710 and a predetermined inserted image object 720 to form a scene of the storytelling content, then, at operation A, the second controller 250 calls the selected background object 710 and inserted image object 720 from the second storage section 240.
Thereafter, at operation B, the second controller 250 performs a control so that the called background object 710 and inserted image object 720 are displayed in the above-described scene formation area of the second display apparatus 200. For example, the second controller 250 transmits the data to the second display section 220 such that the called background object 710 and inserted image object 720 are displayed in the above-described scene formation area of the second display apparatus 200.
Thereafter, at operation C, the second controller 250 transmits identification information about the called background object 710 and inserted image object 720 and position information thereof in the scene, which are not data on the called background object 710 and inserted image object 720, to the first display apparatus 100 through the second communicating section 230. The first display apparatus 100 may receive the identification information about the called background object 710 and inserted image object 720 and position information thereof in the scene through the first communicating section 130.
If the identification information about the objects and the position information in the scene are received through the first communicating section 130, then, at operation D, the first controller 150 calls the background object 711 and the inserted image object 721 corresponding to the identification information from the first storage section 140. As described above, the background object 711 and the inserted image object 721 have the same data as in the background object 710 and the inserted image object 720.
At operation E, the first controller 150 performs a control so that an image formed by the called background object 711 and inserted image object 721 is displayed in the first display apparatus 100. The first controller 150 arranges the inserted image object 721 in the image according to the position information in the scene. For example, the first controller 150 may control the first display section 120 to display the image formed by the called background object 711 and inserted image object 721.
According to various embodiments of the present disclosure, the second controller 250 may receive an additional object 730 in the scene formation. Because the additional object 730 is not stored in the first storage section 140, the second controller 250 may transmit the additional object 730 together with the identification information and the position information in step C. According to various embodiments of the present disclosure, the second controller 250 may transmit information about the additional object 730 with which the first controller 150 may determine a location at which to retrieve the additional object 730. For example, the second controller 250 may transmit a location of a server (e.g., a web server) storing the additional object 730. The first controller 150 adds the additional object 730 received through the first communicating section 130 to the image displayed in the first display apparatus 100.
In this manner, the same image as the scene of the storytelling content being generated in the second display apparatus 200 may be displayed in the first display apparatus 100.
FIG. 8 is a flowchart illustrating a control method of a second display apparatus according to an embodiment of the present disclosure.
Referring to FIG. 8, when an event of an instruction for generation of the storytelling content occurs at operation S100, the second display apparatus 200 may proceed to operation S110. For example, the second display apparatus 200 may determine whether an event of an instruction for generation of the storytelling content occurs. If the second display apparatus 200 determines that an event of an instruction for generation of the storytelling content does occur, then the second display apparatus 200 may continue to poll for indication of an occurrence of such an event.
At operation S110, the second display apparatus 200 displays a UI for generation of a content scene.
At operation S120, the second display apparatus 200 determines whether an object is selected. For example, the second display apparatus 200 determines whether an object that forms the content scene is selected through the UI.
If the second display apparatus 200 determines that an object that forms the content scene is not selected through the UI at operation S120, then the second display apparatus 200 may end the control method.
If the second display apparatus 200 determines that an object that forms the content scene is selected through the UI at operation S120, then the second display apparatus proceeds to operation S130.
At operation S130, the second display apparatus 200 displays a scene using the selected object.
At operation S140, the second display apparatus 200 determines whether the selected object is the object stored in the second display apparatus 200. For example, the display apparatus 200 determines whether the selected object is the object stored in the second display apparatus 200 in advance or whether the selected object corresponds to a new object.
If the second display apparatus 200 determines that the selected object is the object stored in advance at operation S140, then the second display apparatus 200 proceeds to operation S150 at which the second display apparatus 200 transmits identification information about the called object and position information thereof in the scene to the first display apparatus 100. For example, because the same object is also stored in the first display apparatus 100, the second display apparatus 200 transmits identification information about the called object and position information thereof in the scene to the first display apparatus 100. Thus, the first display apparatus 100 may display the same image as the image of the scene on the basis of the identification information and the position information in the scene.
If the second display apparatus 200 determines that the object is not stored in advance (e.g., that the object corresponds to a new object), then the second display apparatus 200 proceeds to operation S160 at which the second display apparatus 200 transmits the object to the first display apparatus 100. For example, because the same object is not stored in the first display apparatus 100, the second display apparatus 200 transmits the object to the first display apparatus 100. Thus, the first display apparatus 100 may add the object to the image for display.
The above-described embodiment is not limiting, and may be thus modified to various forms. Hereinafter, such modified various embodiments of the present disclosure will be described.
FIG. 9 illustrates an example of a system according to a second embodiment of the present disclosure. FIG. 10 illustrates an example of an information transmission relationship between a first display apparatus and a second display apparatus according to an embodiment of the present disclosure. For example, FIG. 10 illustrates an example of an information transmission relationship between a first display apparatus and a plurality of second display apparatuses.
According to the above-described first embodiment of the present disclosure, the system 1 includes one first display apparatus 100 and one second display apparatus 200. According to such a system 1, the scene formed in the second display apparatus 200 is displayed in the first display apparatus 100 as the image.
Referring to FIG. 9, according to various embodiments of the present disclosure, the system 3 includes a plurality of second display apparatuses 201, 202 and 203 that may be connected to one first display apparatus 100 for communication.
According to various embodiments of the present disclosure, the plurality of second display apparatuses 201, 202 and 203 may be display apparatuses of the same type or model, or may be display apparatuses of different types or models. Further, the plurality of second display apparatuses 201, 202 and 203 is connected to each other for communication.
In this environment, the respective second display apparatuses 201, 202 and 203 may form a scene of storytelling content in cooperation.
Referring to FIG. 10, when generating one scene of the storytelling content in this environment, at operation 810, the same scene is displayed in the plurality of second display apparatuses 201, 202 and 203 to be generable or updatable therein, and the same image as the scene is displayed in the first display apparatus 100.
At operation 820, if any one of the plurality of second display apparatuses 201, 202, and 203 (e.g., the second display apparatus 201) updates the scene by performing addition, deletion, or revision of the object with respect to the scene displayed therein, then, at operations 830, 840, and 850, the second display apparatus that updated the scene (e.g., the second display apparatus 201) respectively transmits update information to the first display apparatus 100 and the other second display apparatuses 202 and 203.
At operation 860, the first display apparatus 100 and the other second display apparatuses (e.g., second display apparatuses 202 and 203) update the scene for formation according to the update information received from the second display apparatus that updated the scene (e.g., the second display apparatus 201).
For example, in the above-described first embodiment of the present disclosure, the second display apparatus 200 transmits the update information to the first display apparatus 100. However, according to the present embodiment of the present disclosure, because the plurality of second display apparatuses 201, 202 and 203 generates one scene of the storytelling content in cooperation, the update information about the scene generated in one second display apparatus 201 is transmitted to the other second display apparatuses 202 and 203 in addition to the first display apparatus 100.
Accordingly, if one second display apparatus 201 updates the scene, the updated content is also reflected in the other second display apparatuses 202 and 203, so that the plurality of second display apparatuses 201, 202 and 203 can generate one scene in cooperation.
Further, because the same image as the generated scene is displayed in the first display apparatus 100, users who respectively use the plurality of second display apparatuses 201, 202 and 203 may easily confirm the scene generation process.
The method of forming the scene of the storytelling content by cooperation of the plurality of second display apparatuses 201, 202 and 203 is not limited to the above-described various embodiments of the present disclosure.
For example, according to various embodiments of the present disclosure, the plurality of second display apparatuses 201, 202 and 203 may respectively generate different scenes. In this case, an image displayed in the first display apparatus 100 may be the same as the scene generated in any one of the plurality of second display apparatuses 201, 202 and 203. Alternatively, the display screen of the first display apparatus 100 may be divided into a plurality of screens, and each scene generated in the plurality of second display apparatuses 201, 202 and 203 may be displayed in each divided screen.
The scenes generated in the plurality of second display apparatuses 201, 202 and 203 may be called when the storytelling content is finally generated. For example, if “scene formation” of the additional option menu 430 (see FIG. 4) is selected in one second display apparatus 201, the second display apparatus 201 may request the other second display apparatuses 202 and 203 to transmit data on the scenes generated therein.
Alternatively, the entire data on the scenes generated in the plurality of second display apparatuses 201, 202 and 203 may be stored in the first display apparatus 100. In this case, if “scene formation” is selected in the second display apparatus 201, the second display apparatus 201 may receive the data on the stored scenes from the first display apparatus 100 to generate the storytelling content.
FIG. 11 is a block diagram illustrating a configuration of a system according to a third embodiment of the present disclosure.
Referring to FIG. 11, the first display apparatus 100 and the second display apparatus 200 may be connected to an external device 10 and a server 20 for communication through a local communication line or a network.
