1 is a view showing a schematic configuration of an entire system for outputting content according to the present invention.

Referring to FIG. 1, at least one

output sharing apparatus

100 or 110 exists for outputting content. The

output sharing apparatus

100 or 100 outputs the content received from the

terminals

102, 104, 112 and 114 located in the short range

wireless communication area

150 and 152 or the

terminals

122 and 124 located in the far wireless communication area through a content output device (not shown) such as a beam project. do. The

output sharing devices

100 and 110 may be implemented as a type of Internet of Things (IoT) device that can be connected to the Internet according to an embodiment.

Here, the content is a video, still image, sound, various document files, the state (battery, etc.) of the output sharing device (100, 110), environmental information (temperature, humidity, etc.) measured by the various sensors in the output sharing device (100, 110) It is various kinds of data that can be exchanged through communication.

Short-range wireless communication means to perform direct communication between the output sharing device and the terminal without a separate repeater, for example, infrared communication, Bluetooth communication, Wi-Fi (WiFi). Long range wireless communication is performed through at least one or more repeaters, for example, Wi-Fi, Long Term Evolution (LTE), and the like.

The

output sharing devices

100 and 110 are connected to input and output ports of various types of content output devices such as speakers, printers, and fax machines as well as image display devices such as beam projectors, liquid crystal displays (LCDs), and light emitting diodes (LEDs). Or may be implemented together as part of the content output device. For example, the output sharing device may be implemented as part of the beam projector.

The server 120 relays content, various control information, etc. between the at least one

output sharing device

100, 110 and the at least one

terminal

122, 124. The server may be implemented as, for example, a cloud server.

1 illustrates a case in which

terminals

122 and 124 located in a remote wireless communication area are connected to

output sharing apparatuses

100 and 110 via a server 120, but the present disclosure is not limited thereto.

Terminals

122 and 124 located in the region may be implemented to directly connect to the

output sharing apparatuses

100 and 110 without passing through the server 120.

2 is a diagram illustrating a configuration of an embodiment of an output sharing apparatus according to the present invention.

Referring to FIG. 2, the output sharing apparatus 100 includes a short range communication unit 200, a long distance communication unit 210, an authority setting unit 220, a content receiving unit 230, a content buffer 240, and a content output unit 250. , The content generator 260 and the content transmitter 270. In addition, according to an embodiment, the output sharing apparatus 100 may further include a camera 262, a microphone 264, various sensors 266, an image display device 252, a speaker 254, and the like.

The short range communication unit 200 communicates with at least one terminal located in a short range wireless communication area.

The telecommunications unit 210 communicates with at least one terminal located outside the short range wireless communication area. At this time, the telecommunications unit 210 may be directly connected to the terminal of the remote communication or via a cloud server or the like.

When communicating with the terminal, the output sharing apparatus 100 may perform user authentication. For example, the output sharing apparatus 100 may perform various authentication processes, such as authentication based on ID / password or authentication using identification information of the terminal. The output sharing apparatus 100 may communicate with each other through a separate registration process in the case of an unauthenticated terminal.

The authority setting unit 220 sets a level of control authority to at least one terminal connected to the communication. The level of control authority can be variously set according to the embodiment. For example, the level of control authority may be the highest level of control authority that can control the output sharing device completely, the level of content transmission authority that can transmit content to the output sharing device, or simply receive content from the output sharing device. There are various settings such as the level.

Referring to FIG. 1, when there is a first group composed of at least one

terminal

102 and 104 connected by short-range communication and a second group composed of at least one

terminal

122 and 124 connected by telecommunication, the authority setting unit 220 ) Grants the highest level of control to one of the

terminals

102, 104 located in the first group. The terminal that has been granted the highest level of control authority has various control rights including whether the output sharing device 100 outputs the content, and can give and retrieve content transmission right to

other terminals

104, 122, and 124 connected to the output sharing device. Have authority

If the above-described authentication process is performed, the authority setting unit 220 may grant a level of control authority according to the control level of each user identified through the authentication process. As another example, the authority setting unit 220 grants the highest level of control authority to any one of the

terminals

102 and 104 located in the first group, and gives the other terminal the control authority of the preset basic level, The terminal that is granted the level of control authority can change or set the level of control authority of the remaining terminals.

The content receiver 230 receives content from at least one or more terminals connected through short range wireless communication or long range wireless communication. If a separate transmission authority is required for content transmission, each terminal receives the content transmission authority from a terminal having the highest level of control authority and transmits the content to the output sharing apparatus. According to an embodiment, the terminal that is granted the content transmission right may be allowed to transmit content only for a predetermined time or the number of content transmission may be limited to one or more predetermined numbers.

The content buffer 240 stores content received from at least one terminal. Since the size of the content buffer 240 is limited, it is preferable to delete the content output through the content output unit 250 in the buffer. The deleted content may be stored by moving to a separate storage space that is externally or embedded in the output sharing apparatus 100 according to an embodiment. The content buffer 240 checks the free capacity of the buffer and the terminal having the highest level of control of an error message, etc., when there is no more space for content reception or when the capacity of the received content is large and not all of the content is properly stored. Send the content to the terminal.

The content output unit 250 outputs at least one or more contents stored in the content buffer 240 through various content output devices such as an image display device 252, a speaker 254, and a printer. For example, the content output unit 250 may output a video, an image, a PPT (PowerPoint) file, or the like through a beam projector.

If a plurality of contents are stored in the content buffer 240, the content output unit 250 sequentially displays the contents according to the receiving order, selects and displays specific contents regardless of the receiving order, or divides the screen to display the plurality of contents. Contents can be displayed at the same time. In this case, the display order of the contents or the type of the contents to be displayed simultaneously may be controlled by a terminal having control authority. For example, the terminal having the highest level of authority may select content to be displayed from among contents stored in the content buffer 240 or may select the number of screen divisions and the content to be displayed on each division screen. The content output unit 250 displays the corresponding content according to a control command such as the display order or the number of displays received from the terminal. Of course, the rights of the highest level and the rights of the content output control may be separated from each other and granted to different terminals.

When displaying the contents of the PPT material through a beam projector or the like, the page of the PPT material displayed on the screen is determined according to the control signal input by the user through the output sharing device or the terminal. Therefore, it is not enough to simply share the contents of PPT data when you want to conduct a meeting or lecture while viewing the same page of PPT data as well as the users located in the space where the beam projector is located. In other words, when seven pages of current PPT material are displayed through a beam projector, a remote user who has simply received the contents of the PPT material (ie, a PPT file) does not know that the seven pages are currently displayed.

In order to solve this problem, the content content generation unit 260 and the content transmission unit 270 will be described below.

The content generator 260 generates content including information input through the camera 262, the microphone 264, the sensor 266, and the like. In the example above, the content generator 260 generates content obtained by photographing the screen currently output through the beam projector with the camera 262. Alternatively, the content generator 260 may generate content including a user's voice, etc., along with a camera photographed image where the beam projector is located through the microphone 264.

The content transmitter 270 transmits the content generated by the content generator 260 to at least one terminal through short range wireless communication or long range wireless communication. Since the user located in the short range wireless communication area can directly view the content output by the content output unit 250, according to an embodiment, the content transmitter 270 may omit content transmission to a terminal located in the short range wireless communication area. Can be.

The content transmission unit 270 may directly transmit the content to a terminal located remotely, or may transmit the content via the salping server 120 in FIG. 1, and FIG. 4 illustrates a specific example of content transmission through the server 120. Will be explained again.

3 is a flowchart illustrating an embodiment of a content output method using an output sharing apparatus according to the present invention.

Referring to FIG. 3, at least one terminal 102 or 122 located in the short range communication region 150 and the long range communication region 160 connects communication with the output sharing apparatus 100 (S300 and S305). The output sharing apparatus 100 grants control rights to the connected terminals 102 and 122 (S310 and S315). The highest level control authority for controlling various functions and the like of the output sharing apparatus 100 is preferably given to the terminal 102 located in the short range communication area. In the case of this embodiment, it is assumed that the terminal 102 of the short-range communication area is given the highest level of control authority.

The terminal 102 of the short range communication area granted the highest level of control authority grants the content transmission right to the terminal 122 of the remote communication area (S320). More specifically, when the terminal 102 of the short-range communication area transmits the control information for granting content transmission rights to the terminal of the telecommunication area to the output sharing apparatus 100, the output sharing apparatus 100 may transmit the control information to the terminal of the telecommunication area. Deliver to 122. The output sharing apparatus 100 may provide the terminal list to the terminal having the highest level of control so that the terminal having the highest level of control may easily grant the content transmission authority to the other terminal.

The output sharing apparatus 100 stores the received content in the content buffer and outputs the content stored in the content buffer through a beam projector or the like (S340).

In addition, the output sharing apparatus 100 generates a content by photographing the screen output through the beam projector, etc. through a camera, a microphone (S350). The generated content is transmitted to each terminal (S360, S365). According to an embodiment, the step S360 of transmitting content to a terminal in a short range wireless communication area may be omitted.

4 is a flowchart illustrating an embodiment of a method of outputting content using a server according to the present invention.

Referring to FIG. 4, the server 120 is connected to a plurality of

output sharing apparatuses

100 and 110 and a plurality of

terminals

122 and 124. When the

output sharing apparatuses

100 and 110 provide content by directly connecting to a plurality of

terminals

122 and 124 located in a long distance, a large bandwidth for communication with each terminal is required. For example, if a large amount of content such as video content is transmitted to a large number of remote terminals, transmission of the content may be delayed due to limited bandwidth, and thus it may be difficult to achieve a purpose such as a real-time meeting or lecture. To this end, the plurality of

output sharing apparatuses

100 and 110 are not directly connected to the

terminals

122 and 124, but provide content to the

terminals

122 and 124 through a server 120 (eg, a cloud server) that utilizes resources such as bandwidth more smoothly. do.

The server 120 grasps and stores a mapping relationship between the plurality of

output sharing apparatuses

100 and 110 and the plurality of terminals 122 and 124 (S400 and S405). For example, the server 120 may provide a list of a plurality of

output sharing apparatuses

100 and 110 to the terminal so that the user may select a specific output sharing apparatus or receive identification information of the output sharing apparatus from the terminal. The output sharing device mapped with the terminal may be specified. In the present embodiment, for convenience of description, it is assumed that the first output sharing apparatus 100 is mapped to the first terminal 122 and the second output sharing apparatus 110 to the second terminal 124.

When the server 120 receives the contents from the plurality of output sharing apparatuses 100 and 110 (S410), after grasping which terminal the contents of each

output sharing apparatus

100 and 100 should be provided to based on the mapping information (S415), the contents are determined. To transmit to the terminal (S420). For example, since the first output sharing apparatus 100 and the first terminal are mapped, the server 120 provides the first terminal 122 with content received from the first output sharing apparatus 100.

On the contrary, when the

terminals

122 and 124 intend to transmit the contents to the

output sharing apparatuses

100 and 110, the server 120 receives the contents from the terminals 122 and 124 (S430) and is mapped with each terminal based on the mapping information. After identifying the output sharing apparatus (S435), the content is transmitted to the corresponding output sharing apparatuses 100 and 110 (S440).

Referring to FIG. 5, the terminal communicates with the output sharing apparatus through short range wireless communication or long range wireless communication (S500. S540). The terminal may be various types of terminals capable of short-range communication and long-distance communication, for example, a smartphone, a tablet PC, and the like. The terminal may include an application for performing the method according to the embodiment of FIG. 5.

First, when connected by short-range wireless communication (S500), the terminal is given a level of control authority from the output sharing device (S510). The level of control authority may be variously set according to an embodiment. In this embodiment, it is assumed that the highest level of control authority is given to a terminal connected through short-range wireless communication.

The terminal that has been granted the highest authority grants the content transmission authority to the other terminal that needs the content transmission (S520). In addition, the terminal may directly transmit the content to the shared output device or receive the content from the shared output device as needed (S530).

Next, in the case of being connected by remote wireless communication (S540), the terminal may be directly connected to the output sharing apparatus or connected to the output sharing apparatus via the server as shown in FIG. Although not illustrated in the present embodiment, when sharing through a server, as shown in FIG. 4, a process in which the terminal selects a connection target output sharing device may be added.

When the connection with the output sharing device is established, the terminal is given a level of control authority from the output sharing device (S550). At this time, the remote terminal is generally given the authority level of the content reception and receives the content from the output sharing device (S550).

If the content is to be transmitted to the output sharing apparatus, the terminal should be given the right to transmit the content. The terminal requests the output sharing apparatus to grant the content transmission authority. The terminal having the highest level of control authority determines whether to grant the content transmission authority after receiving the request for granting the content transmission authority from the output sharing apparatus. If the content transmission authority is granted from the terminal of the highest authority (S570), the terminal transmits the content to the output sharing apparatus (S580).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
