For example, a monitor device such as a conventional CRT monitor, an LCD monitor, a smart TV, or the like may be used, a monitor device of a type including a touch panel may be used, or a display device of a type having a screen and a projector may be used.

Hereinafter, the smart cooperation system 100 will be described in detail with reference to the drawings.

1 is an example of a block diagram illustrating a configuration for a smart collaboration system 100. As shown in FIG.

The smart collaboration system 100 includes two types of display devices. One is the main display device 150 that can be watched by the participants, and the other is the group display device 120 that can be viewed by participants in the group unit. The group display device 120 is a device for displaying a screen of a terminal 110 (hereinafter referred to as a participant terminal) held by one participant in the group. The group display device 120 wirelessly receives image data from the participant terminal 110 and outputs the image data. The main display device 150 is basically a device that outputs one of the screens output to the group display device 120. The main display device 150 may select and display a screen of one of the participant terminals regardless of the group.

Figure 1 illustrates, by way of example, three groups. Group 1 includes participant terminal a 110a and participant terminal b 110b, Group 2 and Group 3 are similar in structure to Group 1, and the number of Groups is not limited to three shown in FIG. 1 . Although each group includes two participants (participant terminals), the number of participants in each group may vary.

The participant terminal 110 may transmit the content displayed on the display window of the participant terminal to the video receiver 130. [ The contents displayed on the display window correspond to the constant image data. Therefore, in the following system, data transmitted and received by each configuration is referred to as image data. In FIG. 1, the participant terminal b 110b transmits image data to the image receiver 130 in Group 1, the participant terminal d 110d in Group 2 transmits image data to the image receiver 130, And the participant terminal f (110f) transmits the image data to the image receiver (130). The process of transmitting image data between the participant terminal 110 and the image receiver 130 will be described later.

The participant terminal 110 transmits the image data to the image receiver 130 using wireless communication. The video receiver 130 transmits the received video data to the video controller 140 and the video controller 140 controls the participant terminals 110 belonging to each group to the group display devices 120a, 120b, and 120c And transmits the transmitted image data. The group display device 120 receiving the image data outputs the corresponding image data.

The image receiver 130 shown in FIG. 1 should be capable of transmitting and receiving a plurality of image data at the same time. 1 illustrates a method of transmitting image data received by the image receiver 130 to the image controller 140 and distributing image data received by the image controller 140. However, And may transmit the received image data to each group display device 120 according to a control command of the control device 140.

In the smart collaboration system 100, the main display device 150, the image control device 140, the image receiver 130, and the group display device 120 are wired.

In FIG. 1, one participant terminal 110 belonging to each group transmits image data to the image receiver 130. However, in some cases, a plurality of participant terminals 110 belonging to the same group simultaneously transmit image data To the image receiver (130). In this case, the image control device 140 controls to receive only image data transmitted from any one of the participant terminals 110 belonging to each group, or only one of the plurality of received image data is displayed as a group display To be transmitted to the device (120).

Various methods can be used for selecting one of the video data of the participant terminal 110 belonging to each group and transmitting the selected video data to the group display device 120 belonging to each group. Basically, a specific participant terminal 110 can be selected according to an external input. The input device 141 is an information input device of the image control device 140 in which a host or a participant receives a command to select an image to be output to the group display device 120. [ Further, the input device 141 may receive a command for selecting an image to be output to the main display device 150 among the image signals received by the respective groups. The pivotal role of all selection and control is performed by the image control device 140. The image control device 140 corresponds to a kind of video router.

There are various methods for selecting an image output to the group display device 120 through the image control device 140, and an example will be described below. The image receiver 130 obtains the identifier of each group terminal 110 and receives image data wirelessly transmitted from the participant terminal 110 of the group together with the corresponding identifier information and transmits the received image data to the image control device, 140 can confirm which participant terminal 110 transmits the received image data.

2 is another example of a block diagram illustrating a configuration for the smart education system 100. [ The difference from FIG. 1 is that the image receiver 130 is arranged for each group. FIG. 2 illustrates an example in which Group 1 and Group 2 are included, and each group includes three participant terminals 110. Figure 2 also shows the moderator terminal 160. The image receivers 120a and 120b shown in FIG. 2 transmit one of the image data received by the image receivers 120a and 120b to the group controller 120 and the image controller 140, respectively.

The image receiver a 130a can receive image data from the participant terminals 110a, 110b, and 110c belonging to Group 1. The image receiver b 130b may receive image data from the participant terminals 110d, 110e, and 110f belonging to the group 2. Each of the image receivers 130a and 130b may output only one of the images of the participant terminal 110 of the group to which the image receiver 130a or 130b belongs.

The image controller 140 controls the main display device 150 to select only one of the image data received by the image receivers 130a and 130b. A control method similar to the method described with reference to FIG. 1 can be used, and more specifically, it can be implemented easily by utilizing the function of a wired video router. Accordingly, the image controller 140 can select one of the image data simultaneously received by the image receiver 130 and control the image data to be output to the main display device 150.

Furthermore, since the video receiver 130 is disposed in each group, if one participant terminal 110 establishes a network channel for transmitting video data, the other terminal can be prevented from transmitting video data. For example, when the participant terminal a (110a) first transmits video data to the video receiver a (130a) in Group 1, the other participant terminals (110b, 110c) can not transmit video data. To this end, a process is required in which the participant transmits image data to the image receiver 130 in order to share the image of the participant himself / herself. A step of establishing a short-range wireless communication channel with the image receiver 130 will be required in advance. The communication channel between the participant terminal 110 and the video receiver 130 may be various conventional communication techniques.

The host can input a command to select an image to the image control device 140 through the host terminal 160. [ The host terminal 160 and the image control device may be connected by wire. Further, the host terminal 160 may transmit a command to the image receiver 170 to wirelessly select an image, and may transmit the command to the image controller. The image to be outputted to each group display device 120 can be selected according to the selection command transmitted from the master terminal 160 and the image transmitted from the image receiver 130 to the image control device 140 150 may be selected.

Further, the host terminal 160 may transmit its own image data to the image control device 140 through the image receiver 170. The related contents will be described later.

In summary, the smart collaboration system 100 is a portable terminal used by a participant belonging to a specific group of a plurality of groups, and is a participant terminal 110 and a participant terminal 110 that wirelessly transmit image data through a communication module A group display device 120 for receiving and outputting image data of a participant terminal assigned to a specific group from a video receiver and belonging to a specific group, A main display device 150 for outputting image data of at least one participant terminal 110 belonging to different groups and a command for selecting image data outputted to the main display device 150 among the image data received by the image receiver And an image control device 140 for receiving the selected image data and transmitting the selected image data to the main display device 150 The.

The image control device 140 may store the identifier information for the participant terminals belonging to the specific group and the specific group and may be transmitted by any one of the participant terminals belonging to the specific group using the identifier information.

The image control device 140 transmits one of the image data output to the group display device 120 to the main display device 150 or two or more pieces of image data output to the group display device 120 to the main display 150 150).

The video receiver 130 includes a video data conversion module including a plurality of OSs or protocols for a plurality of platforms, identifies the type of video data transmitted by the communication module of the participant terminal according to its OS or platform, A protocol suitable for the data can be selected and converted into a video data format that can be output from the group display device 120 or the main display device 150. [

FIG. 3 is an example of a block diagram illustrating the configuration of the participant terminal 110 and the image receiver 130. Referring to FIG.

An image output to the participant terminal 110 may be output to the group display device 120 or the main display device 150 in real time. A method of sharing images using wireless communication is also referred to as a wireless display. There are various software and protocols for wireless display. The smart collaboration system 100 may use various schemes for conventional wireless display.

The participant terminal 110 does not show all the configurations and shows only the configuration related to the video data transmission. The participant terminal 110 outputs to the display 112 a certain content created or created by the participant. It is assumed that image data for an image output to the display 112 is output through a predetermined cache memory 111. [ The image data stored in the cache memory 111 corresponds to the contents output in real time on the display 111. The image data is transmitted to the image receiver 130 through the communication modules 113 and 114.

As described above, the participant terminal 110 can use different OSs or platforms. In this case, the format of image data to be transmitted wirelessly may be different, or the wireless communication protocol for transmitting data may be different. The wireless communication protocol can be WiFi Direct, IEEE 802.11ac, MS Widi, Samsung dongle, etc. The wireless communication protocol may be a dedicated protocol for transmitting image data or a protocol for transmitting general data.

The communication module 113 corresponds to a communication module built in the participant terminal. The participant terminal 110 transmits the image data to the communication module 131 of the image receiver 130 through the communication module 113 and the image receiver 130 transmits the received image data to the group display device 120 or the main It needs to be converted into a form that can be output to the display device 150. [ This is because the image format, image size, resolution, and the like used by the participant terminal 110 for video output may be different from each other. This information is called image data information.

The image data conversion module 132 performs a function of converting different image data according to the OS or platform type of the participant terminal 110. [ The image data conversion module 132 stores image data information according to various types of OSs or platforms, identifies the OS or platform to which the received image data corresponds, and processes the data. The image data conversion module 132 may analyze the characteristics of the image data to determine which OS or platform it is and may also check which OS built platform is using the image data information transmitted together with the image data. However, the video data conversion module 132 may not be an essential configuration. Even if the image data is transmitted to the display device without conversion, there is no problem in identifying the image.

The image data converted by the image data conversion module 132 is transmitted to the group display device 120 through the interface 133. Or may be transmitted to the main display device 150 via the image control device 140.

Further, the system configuration is possible even if the image receiver does not include the image data conversion module 132 and the image control device 140 includes image data protection or modules.

The communication module 114 of the participant terminal 110 corresponds to the external communication module. For example, the communication module 114 connected to a terminal such as a USB can perform one-to-one communication with the communication module 131 of the video receiver 130.

3, the video receiver 130 receives video data of all OSs and platforms using a separate wireless set-top box. That is, it is an example of using a separate protocol for video data transmission.

Furthermore, the image receiver 130 may be implemented by including a dongle (data transmission / reception device) for all OSs or platforms in parallel and connecting the dongle to a video switcher. In this case, image data is wirelessly transmitted according to the platform of each participant terminal 110, and the image receiver 130 receives the image data transmitted from the corresponding dongle.

4 is another example of a block diagram illustrating the configuration of the participant terminal 110 and the image receiver 130. Referring to FIG. 4 illustrates a case where the video receiver 130 includes communication modules for all the OSs and platforms of the participant terminal 110. [

When the image receiver 130 receives the image data through the communication modules 131a, 131b and 131c, the switcher 134 can select the image data received from any communication module. The image data is transferred to the group display device 120 or the like via the image data conversion module 132 if necessary.

Fig. 5 shows an example in which the participant's image data is shared in a group in the smart collaboration system 100. Fig. 5 and 6 are based on the smart collaboration system 100 shown in FIG.

In the group 1, the participant terminal 110 transmits image data to the image receiver a 130a. The host transmits the control command 1 to the video controller 140 through the host terminal 160 so that the video of the participant terminal a 110a is output from the group 1. The image control device transmits the corresponding control command to the image receiver a 130a and the image receiver a 130a causes the image of the participant terminal a 110a to be output to the group display device a 120a. Meanwhile, in Group 2, the image data of the participant terminal d 110d is selected.

The image receiver a 130a transmits the image data of the participant terminal a 110a to the image controller 140 and the image receiver b 130b transmits the image data of the participant terminal a 110a to the image controller 140 of the participant terminal d 110d . The host terminal 160 transmits the control command 2 to the video control device 140 so that the video data of the participant terminal d 110d is transmitted to the main display device 150. [

Fig. 6 shows an example in which the image data of the moderator is shared in the group in the smart collaboration system 100. Fig. FIG. 6 is a flowchart illustrating a process of delivering training content to each group by a facilitator through the smart collaboration system 100. FIG. The operator terminal 160 transmits the image data of the operator terminal to the image receiver 170 and simultaneously transmits the control command to the group 1 and the group 2 so that the image data of the operator terminal is transmitted. The control command may be transmitted to the image control device 140 directly or wired or wirelessly via the image receiver 170.

Then, the image control device 140 transmits the image data of the host terminal to the group display device a 120a and the group display device b 120b. The participant refers to the image output to the group display device 120 and conducts training and meeting.

The smart collaboration system 100 is capable of training in a traditional top-down manner.
