At this time, each element may be used as a superordinate concept, and may include one or more sub-elements that contain more detailed information about the element as a sub-concept. In the context of the present invention, the errorEvent element may include, for example, at least one or more of the sub-elements as shown in FIG. 6, described below.

The metadata 5000 format and elements shown in FIG. 5 are only examples for facilitating understanding of the present invention and for convenience of description of the present invention, and the present invention is not limited thereto or limited thereby. For example, some of the metadata 5000 shown in FIG. 5 are not excluded or shown, but other elements may be added. On the other hand, the metadata between the devices in the digital signage system does not necessarily need to be transmitted / received as shown in FIG. 5, but may be transmitted / received only with the necessary element (s) according to a necessary event.

Other data or a reserved element 5090 for future use may include information on content information to be changed according to a target, a kind of a related product, and the like. As described above, the reserved element 5090 can be easily inserted, changed, and expanded by ensuring flexibility so as to include information such as change information and frequent modification.

As described above, using the metadata 5000 according to the present invention, it is possible to determine whether a generated content is executed in which display device 5010, which player (hardware type, software type, etc.) It is possible to easily transmit and receive data on the network transmission path 5050 and the like, and the server can perform distribution and transmission of contents more efficiently.

On the other hand, the metadata 5060 can be used to easily collect the actual output of the content in the terminal, and can be used for various purposes or purposes such as advertisement effect measurement.

In particular, an error management / processing method of the digital signage system will be described with reference to the present invention as follows. Here, FIG. 6 illustrates sub-elements of the errorEvent element 5080 in the metadata 5000 of FIG. 5 described above.

The errorEvent element 5080 in FIG. 5 is for definition of all error events occurring in the digital signage system or in the course of its operation. For example, such error events may include error events related to network, device, player, Lt; / RTI >

Referring to FIG. 6, the errorEvent element 5080 includes a DeviceID sub-element 6010 including an identifier of a corresponding device for identifying an error-occurred device, a startTime sub-element 6020 for a time at which an error occurred in the device, An errorCause sub-element 6030 that can include all the information about the error such as the type and the cause of the error, a location sub-element 6040 including the location information of the device where the error occurred, Element 6050 that includes information about the manager who is responsible for managing the sub-elements. Here, the error element 5080 may further include an AdditionalData sub-element (not shown) capable of transmitting additional information or the like in addition to the ErrorCause sub-element.

The contact sub-element 5050 includes a contact sub-element 5050 and a contact sub-element 5050. For example, the contact sub-element 5050 includes a contact point related to an error such as a name of a manager of the device, a mobile phone number, an office telephone number, e- and may include a plurality of information about contact points.

The usage scenarios of such metadata can vary widely. In particular, an example of a metadata usage scenario related to errors is as follows.

When the server transmits a message for checking whether an error has occurred periodically or non-periodically to each connected display device, each display device checks its status to check whether or not an error has occurred. If no error has occurred as a result of the confirmation, the display device returns a value to the server. However, if an error is detected in the display device, for example, the metadata elements as shown in FIG. 6 may be collected and included in the metadata as shown in FIG. 5 to be transmitted to the server. The server parses the meta data to identify the cause of the specific error of each display device from the errorEvent element 5080 and respond to the error. In the above example, the role of the server may be replaced by the mobile device. For example, an administrator can check the presence or absence of an error in the display devices using the mobile device, or directly access the display device in which the error has occurred to use it for identifying the specific error cause. In a similar manner, metadata about the presence or absence of errors can be transmitted / received between the mobile device, the server, and the display device.

Hereinafter, a method of performing error management / processing in the digital signage system according to the present invention will be described in more detail with reference to the accompanying drawings with reference to the above description of FIG. 1 to FIG. 6.

As described above, there can be various methods and usage scenarios for error management / processing in a digital signage system. However, in order to facilitate the understanding of the present invention and for the convenience of the applicant's explanation, a method of managing / processing an error occurring in at least one display device using a mobile device in a digital signage system will be described as an example. For this, various UIs and interfaces are exemplified herein, but the scope of rights of the present invention is not limited or limited thereto.

A method of effectively managing / processing an error generated in a display device of a digital signage system using a mobile device according to the present invention can be achieved by, for example, automatically transmitting an error content to a manager in charge of a display device, can do. Here, the content of the error includes, for example, the location of the apparatus where the error occurred, the cause of the error, the time at which the error occurred, and the contact information of the responsible manager. On the other hand, the responsible manager includes, for example, a local person in charge of the display device, a person in charge of the center, a person in charge promised in advance according to the cause of the error, and the like. The predetermined method includes a call, a text message (MMS), an e-mail (E-mail), and the like. In addition, when the error information is transmitted, the mobile device can be provided with an interface such as location information and map information that can easily monitor the device status by intervals in a glance. The present invention can be provided by any one of the above-mentioned various contents or by a simple combination or combination thereof.

Hereinafter, in order to facilitate the understanding of the present invention, a method for notifying a local administrator of a device error and a method for managing an error by monitoring the status of the device as a CCTV manager will be described separately. However, this method has not been set priorities, and the former and latter may be performed in parallel or in reverse order depending on the usage scenario.

7 to 11 are diagrams for explaining an example of a method of notifying an administrator when an error occurs in a device in the digital signage system according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

7 to 11 are basically related to a method of processing an error using a mobile device when an error occurs in a predetermined display device.

Hereinafter, for the sake of convenience, it is assumed that the error management system in the digital signage system is performed through one server, at least one mobile device, and a plurality of display devices.

Here, the mobile device may be associated with at least one or more display devices, for example, a mobile phone, a smart phone, a tablet PC, and a system dedicated device.

Preferably, the mobile device registers linkage information with the display device related to at least one of the server and the display device and the unique information of the mobile device in advance. Here, the linkage information refers to information indicating that the device 1-5 is associated with the mobile device 1 and the device 6-10 with the mobile device 2 when the device 1-10 exists, for example. On the other hand, the linkage means that the display device receives the management / control of the corresponding mobile device, for example, so that data transmission / reception between the registered devices can be performed based on the identifier information and the like, and the process can also be included. At this time, the metadata and error related data shown in FIGS. 5 to 6 may be included in the transmitted / received data. The unique information includes, for example, identification information of the corresponding mobile device, network information for communication with the associated display device or server, and the like. Meanwhile, as described above, the mobile device may register in advance at least one of the server and the associated display device, including information necessary for data transmission and reception, such as identifier information and network information.

On the other hand, the mobile device may download and use a widget application in advance to manage and / or control the associated display device in the digital signage system.

If it is determined that an error has occurred as a result of collecting the status information of the display device, the display device transmits the metadata including the information as shown in FIGS. 5 to 6 to the associated mobile device. Also, the mobile device parses the metadata transmitted from the display device, generates a UI as shown in FIG. 7, and provides the UI on the screen.

The above description is the case where the display device transmits directly to the associated mobile device without going through the server. On the other hand, in addition to the above-described message transmission method, only error-related messages are collected in the display device and transmitted to the server, and the metadata is generated in the server as shown in FIGS. 5 to 6, An error message may be transmitted by transmitting the metadata generated by the mobile device. When transmitting an error message to either the server or the display device, a separate communication server may be used in addition to the server described above.

The error occurrence check of the display device may be performed voluntarily or at the request of a mobile device or a server. Also, the check may be periodic or non-periodic. For example, a server or a mobile device transmits a message or a packet for requesting an error presence check continuously in a polling manner, that is, a predetermined period, and the display device checks whether an error has occurred in response to the request message or packet, The result can be included in the response to send a message or packet.

Referring to FIG. 7, the local administrator obtains information on the name of the display device in which the error occurred, the name of the content that was being executed in the display device, and the cause of the error, from the error message UI 7010 provided on the screen of the mobile device . At this time, the error message UI may include a detailed view button 7012 requesting more detailed information about the error and an OK button 7014 indicating that the error message is confirmed.

The local administrator can confirm that an error has occurred in the predetermined display device by checking the information of Figs. 7 to 8 through the screen of the mobile device. In this case, if the local administrator confirms the error as described above, the local manager must take measures to solve the error problem early. In this regard, an example of the action of the local administrator is to transmit a telephone, an MMS, an e-mail, etc. to the person in charge of the error, as shown in Figs.

Referring to FIGS. 9 to 11, when the local administrator confirms the detailed information on the error as shown in FIG. 8, the local administrator wants to transmit an MMS message to the corresponding error manager in order to solve the error.

In this case, the local administrator selects the MMS using the tab button 9010, as shown in FIG. As shown in FIG. 10, when a local administrator wishes to transmit an MMS message to the corresponding error manager as shown in FIG. 9, a window 10022 for creating a message to be transmitted to the error manager is provided in a predetermined area on the screen of the mobile device do. In addition, the local administrator places a tab icon 10024 in the window 10022 to create a message, and a means for inputting a message is provided in a predetermined area 11020 of the screen, as shown in FIG. Here, the means may be, for example, a virtual keyboard board. In addition, it is preferable that the means is located at the lower end of the window 11010. 11, the local administrator accesses the pre-provided window 11010 and uses the tab icon 11030 to display a desired message (" quick action ") when the message input means 11020 is provided. Can be created and transmitted to the corresponding error manager through the enter button.

Referring to FIG. 11, a mobile device may output information about a person to which a message prepared in a top area of the screen is transmitted when a message of a local administrator is created, thereby facilitating the convenience of a local administrator.

The above description has described a method of identifying an error situation in a digital signage system in a mobile device and transmitting the information to the person in charge for early error resolution.

Next, the process of the previous step or the subsequent step of the above-described contents, or a process different therefrom, makes the state of the display device in the digital signage system more convenient and convenient, as the owner of the mobile device, And how to manage errors easily and easily.

12 to 16 are diagrams for explaining another example of a method of notifying an administrator when an error occurs in a device in the digital signage system according to the present invention.

A mobile device has a smaller display screen size than a fixed device because of its advantage that it can be used even in a mobile environment. On the other hand, if there are a large number of display devices in the area or the area covered by the local manager, it may be difficult to output all of them on a screen of the mobile device. In this case, the disadvantage of the mobile device can be solved simply by dividing the mobile device into predetermined units. For example, in the following, a predetermined unit is defined for each layer, for example. However, if the range of the layer unit is wide, it is sufficient to refine the layer unit so that there is no problem in identifying the user.

Fig. 12 can provide various information as shown in Figs. 8 to 11 described above. At this time, for convenience of description, each area is referred to as an area in order to distinguish the parts where information is provided.

The first area is the uppermost area of the screen, as described above, rather than the area where the related information is provided, rather than the area where the basic information of the mobile device is provided.

In the second area 12010, title information for identifying the widget application is provided, and a selection window and a refresh button may be separately provided.

Here, the selection window is for providing selection convenience of related information such as, for example, the layer selection feature of the local administrator, the display device selection feature, and the like. In addition, the refresh button may be provided for returning to a previous screen that is currently executed, or for performing a refresh function for real-time updating.

The third area 12020 is provided with a layer selected by the selection window of the second area 12010 as a main area (a four-tiered ladies' dress store in Fig. 12) and a text message capable of identifying it (12022) And a UI 12024 for a display device provided in the layer.

In this case, if a free space is left on the screen of the mobile device or a fourth area 12030 may be provided according to the setting.

Here, the fourth area 12030 may include, for example, an information area for UIs 12032 and 12034 or a separate third area 12020 for the layer adjacent to the layer of the third area, Key region, and so on.

Meanwhile, the mobile device includes a touch screen, and if the user moves the third area 12020 or the fourth area 12030 in one of the up, down, left, and right directions, the layer information may be provided.

On the other hand, the screen showing each display device in the third area 12020 shown in FIG. 12 may be image data or video data. For example, it may be a captured image or a screen shot of the current output screen received according to a screen request of the user as shown in FIG. 12 from the display devices. On the other hand, in FIG. 12, when a predetermined display device does not provide any content other than an error, it substitutes a black screen for the display, or identifies a predetermined image or a current content is not provided Text, and the like. In this case, the mobile device may directly or indirectly control the content providing device through the server according to the selection of the local administrator. This is because, for example, if the UI provides a black screen, there is a concern that the local administrator mistakes it as an error.

FIG. 13 shows a screen UI 13010 in which an error has occurred in a predetermined display device of a 4th layer women's wear store according to the above description. In this case, the mobile device receives the meta data as shown in FIGS. 5 to 6 from the corresponding display device or server and confirms the received meta data to form a screen as shown in FIG. 13 and provide it to the local administrator.

On the other hand, as shown in FIG. 13, when the local administrator clicks or selects the corresponding screen 13010 using the tab icon 13012, the mobile device can provide the screen UI shown in FIG. For example, FIG. 14 shows a screen in the same manner as in FIG. 8 described above. However, the paths are different from each other in Fig. 8 and Fig. 14, and it is the same that the display device in which an error has occurred is grasped and detailed information about it is provided. Of course, it goes without saying that the screen configuration can be configured differently from that shown in FIG. FIG. 15 also shows a screen in the same manner as FIG. Therefore, the detailed description of Figs. 14 and 15 is based on the description of Figs. 8 to 9, and a detailed description thereof is omitted here.

On the other hand, when the user requests a phone call to the corresponding error manager using the tab button 15010 on the screen of FIG. 15, the mobile device provides a screen as shown in FIG. 16 and can provide additional information.

For example, in FIG. 16, the first area 16010 may indicate that the telephone is currently connected with information such as the contact name and the name of the corresponding error manager, and the second area 16020 may display a picture of the contact person . In this case, if the photograph of the person in charge is not registered in advance, a substitute image may be provided. On the other hand, the third area 16030 provides a function key. Here, the function key may be a key for the call termination function. Meanwhile, the function key may include various function keys that can be generated in the telephone connection process as well as termination of the call as shown in FIG.

An exemplary method of controlling a digital signage system using a mobile device according to the present invention includes downloading and installing a first application for error management / processing, checking whether an error has occurred in the display device through the first application Requesting and receiving a response, generating an error display UI (User Interface) according to the response, outputting the UI, and managing and managing errors using the error display UI.

Here, the control method may include mutually authenticating at least one of a server that controls the entire digital signage system through the first application and a display device associated with the mobile device, and at least one of the mutually authenticated server and the display device The method may further include the step of registering.

The control method may further include confirming a network connection state and requesting the first application to a web or a server via a connected network.

The control method may further include requesting and downloading a second application for system management to the web or server, monitoring the status of the display device through the second application, And outputting detailed information on the generated error of the identified display device.

Meanwhile, the error detailed information may include at least one of an error status screen shot, an error status list, a contact point for processing the error status, and link information thereof in the display device. In addition, the request and response may be in the form of a message or packet, and the message or packet may include metadata regarding the request and response.

FIG. 17 is a diagram illustrating a data transmission protocol between a mobile device and a display device according to an embodiment of the present invention. Referring to FIG. 17, an embodiment of a data transmission protocol between a mobile device and a display device will be described.

The mobile device outputs the list information of the source device (S110). The source device may include a central server of the digital signage system and the mobile device as a device for providing content.

A signal for selecting a specific source device from the list information of the source device is received from the user (S120). If the selected specific source device is the mobile device, content is generated (S130). The content may be a photo, a moving image, a picture file, or the like stored in a mobile device. The content may be created by adding or editing text, and may have various data formats to be displayed on a display device.

A signal for selecting a display device to distribute the generated content is received from the user (S140). There may be a plurality of display devices to distribute the contents, and a display device including a plurality of display devices other than the display device individual selection may be selected for each group.

When a display device to distribute content is selected, the generated content is transmitted to the selected display device (S150). The display device receiving the content displays the received content (S160). Content, meta data of the content and received information can be stored in a separate memory. In addition, the content distribution status information may be transmitted to the mobile device using the stored data (S170). The distribution status information may include information such as whether or not the transmission is completed, when the transmission is completed, and the like.

The mobile device can collect content distribution status information for a plurality of display devices using the content distribution status information received from the display device (S180). The collected information can be used as a reference material for setting the advertisement effect measurement and the content distribution schedule in the future. In addition, the distribution status information may be output from the mobile device at the request of the user (S190).

FIG. 18 is a flowchart of a method of controlling a mobile device according to an embodiment of the present invention. Referring to FIG. 18, a method of controlling a mobile device will be described. However, the same elements as those described in the entire system for distributing content from the mobile device to the display device will not be described in detail.

First, list information including the first source device and the second source device is output (S210). The source device may be a plurality of devices for providing content, the first source device may be a mobile device, and the second source device may be a central server of the digital signage system.

A signal for selecting a specific source device from the user through the user interface of the mobile device is received (S220). If the specific source device is the first source device (S230-Yes), at least one display device capable of communicating with the first source device is grouped, and the graphic data for the group or And outputs graphic data corresponding to each of the display devices belonging to the group (S240). It is also within the scope of the present invention that a group can be output for each source device, and a display device is directly output without a group.

When the user receives a signal for selecting a display device belonging to the group or the group using the graphic data (S250), the content to be distributed to the selected display device is generated (S260). The user interface and the display unit of the mobile device can provide a convenient tool so that the user can easily create the content easily. At this time, the step S260 may be performed after the steps S240 and S250, but the order is not limited thereto, and may be performed before the step S260.

The generated content is transmitted to the selected display device (S270). In this way, content can be easily generated and transmitted in the mobile device, which is the first source device, so that real-time content creation and display can be performed, and it is possible to respond quickly to the scene where the display device is placed.

In addition, since the content generated by the first source device can be transmitted to the display device, the first source device can control the display device without a separate remote controller, thereby enhancing the user's convenience.

Accordingly, when the remote control of the display device selected by the user is requested through the user interface of the first source device, the mode of the first source device is changed to the remote control mode. When the mode is changed, a control signal may be wirelessly transmitted to the selected display device according to a predetermined protocol to remotely control the display device from the first source device (S280).

On the other hand, if the specific source device is not the first source device (S230-No), the specific source device may be the central server of the digital signage system, that is, the second source device. Accordingly, the specific content to be distributed is selected from the contents stored in the second source device (S290). Of course, it is also possible to request new content from the central server and select newly created content.

(S300), displaying at least one of the at least one display device capable of communicating with the second source device, and displaying the graphic data corresponding to the group or each of the display devices belonging to the group, A signal for selecting at least one display device to distribute the content is received from the user (S310).

The selected content is transmitted to the selected display device (S320). At this time, the central server may transmit a transmission request signal to the central server for direct transmission to the display device, or the mobile device may receive the content from the central server and transmit the content directly to the display device.

Although not shown in FIG. 12, the mobile device can receive status information, in which content is distributed to at least one display device, from the central server or the at least one display device.

The mobile device may generate graphic data corresponding to the received status information and output the generated graphic data. By providing the content distribution status information to the user, it is easy to know the distribution status in the mobile device and can respond quickly when the distribution is not smooth.

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. It is also within the scope of the present invention to design a computer-readable recording medium in which a program for executing the previously described embodiments is recorded according to the needs of those skilled in the art.

The mobile device and its control method according to the present invention are not limited to the configuration and method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments may be modified Or may be selectively combined.

FIG. 19 is a diagram illustrating a data transmission protocol between a server, a mobile device and a display device according to the present invention, and an embodiment of a data transmission protocol between the mobile device and the display device will be described with reference to FIG.

The mobile device searches for a communication device capable of communicating using location information or the like at a predetermined time interval (S410). When a communicable display device is found, the mode is changed to the control mode (S420), and the control target list is output (S430). In this way, when there is a communicable display device, the control mode is automatically changed so that the control target list can be automatically output when the display device comes near the controllable display device, thereby enhancing the user's convenience.

A signal for selecting a display device from at least one control object included in the control target list is received from the user interface (S440). If the command data is not stored in the mobile device for the display device, the management data for the display device is requested from the server (S450).

In step S460, the server inquires the rights information of the manager of the mobile device, and if it is authorized, the management data for the display device is transmitted in step S470. If you do not have authorization, you can decide to grant authorization and then transfer the management data after authorization.

The management data may include at least one of identification information and status information of the display device, content information to be transmitted to and executed by the display device, schedule information to be executed, and whether to transmit the content.

The mobile device that has received the management data from the server generates and outputs the command data for controlling the display device (S480). The command data includes information for controlling the display device, and also includes graphic data for a control menu to be selected from the user. Thus, the command data may be at least one.

Upon receiving a signal for selecting specific command data from the user interface (S490), a control signal corresponding to the specific command data is extracted with reference to the memory (S500). The control signal is wirelessly transmitted to the display device according to a predetermined protocol (S510), and the display device is controlled according to the control signal (S520).

The predetermined protocol is a protocol for transmitting and receiving a signal and the like through a wireless communication network, and can use an optical communication, an infrared communication, or the like. According to the protocol, the controller of the mobile device can convert the command data into a control signal format suitable for the protocol and transmit it to the communication unit.

FIG. 20 is a flowchart of a method of controlling a mobile device according to an embodiment of the present invention. Referring to FIG. 20, a method of controlling a mobile device is described. However, the same items as those described in the mobile device will not be described in detail.

It is determined whether the display device is in a communicatable state in a predetermined time unit (S610). The location information may include at least one of an Internet Protocol (IP) address, a MAC address, and a Global Positioning System (GPS). .

For example, it is possible to store a plurality of IP addresses, a MAC address, and the like, and determine whether communication is possible by sequentially attempting to access the stored plurality of IP addresses, MAC addresses, and the like in a predetermined time unit. Further, if the mobile device is present at a position based on the pre-stored GPS, it may be determined whether there is a display device capable of communicating at a close distance.

However, it is also within the scope of the present invention to determine whether there is a display device capable of communicating via a local area network such as bluetooth even if it is not location information.

If the communication mode is enabled, the mode of the mobile device is changed to the control mode (S620), and a notification message or the like can be displayed so as to inform the user of the change.

When the mode is changed to the control mode, a control target list including at least one of a communicable display device, content that can be displayed on the display device, and a content distribution device that transmits content to the display device is output in operation S630.

Upon receipt of a signal for selecting a specific control target in the control target list (S640) from the user interface (S650), at least one command data for controlling the specific control target is output (S660).

The command data includes information for controlling the controlled object, and includes graphic data for a menu for controlling the controlled object.

When the specific control target is a display device, the selection command of the content distribution device, the power control command of the display device, the volume control command of the display device, and the content playback control command being displayed on the display device, It is possible to generate and output graphic data corresponding to at least one.

When the specific control target is the content distribution apparatus, a power control command of the content distribution apparatus, a content selection command to be distributed by the content distribution apparatus, a content transmission command to the display apparatus from the content distribution apparatus, The graphic data corresponding to at least one of the plurality of graphic data can be generated and displayed.

In addition, when the specific controlled object is a content, control is also made for a player that reproduces the content, and graphic data corresponding to at least one of a content reproduction control command, a content list selection command, a specific content selection command, Can be generated and output.

At this time, in order to generate the command data, the mobile device requests the management data for the specific control object to the server, and can generate the command data using the management data.

The management data may include at least one of identification information and status information of the display device, content information to be transmitted to the display device, schedule information to be executed, and whether to transmit the content.

At this time, if necessary, the server may inquire the authority information to determine whether it is authorized to control the specific control object, and if the authority information does not exist, the authority setting may be granted from the server.

On the other hand, if there is room in the memory of the mobile device, the control object, command data for each control target, graphic data corresponding to the command, and the like are stored, and the command data can be output with reference to the memory as needed.

Upon receiving a signal for selecting specific command data among at least one command data through the user interface (S660), the specific command data is converted into a control signal (S670). It is possible to use a predetermined protocol for matching the command data and the control signal in order to convert it into the control signal.

The control data corresponding to the command data and the command data may be stored in the memory and the control signal corresponding to the specific command data may be extracted. However, in this case, it is necessary to separately store a control signal corresponding to the command data in the memory in accordance with the control object.

The control signal is transmitted to the specific control object (S680). Accordingly, it is possible to control the display device, the content distribution device, or the content in the mobile device, so that the local management is convenient and quick in terms of the user, i.e., the manager.

According to the present invention, it is possible to satisfy both an advertiser, an advertisement producer, and an advertisement content user by providing an interactive digital signage system. In addition, the advertiser can directly participate in the production and control processes of the advertisement to generate contents that are more in conformity with his / her intention, thereby maximizing the advertisement effect by inducing the satisfaction of the user and the desire to purchase. In addition, the user can easily access the advertisement contents output through the display device of the interactive digital signage system, thereby easily and conveniently obtaining the information desired by the user.
