Can be integrated, added or omitted.

Hereinafter, embodiments of a method for displaying content in a digital signage system will be described in more detail with reference to FIGS. 3 to 9.

3 is a flowchart illustrating a content display method according to an embodiment of the present invention. The illustrated content display method will be described with reference to the block diagrams shown in FIGS. 1 and 2.

Referring to FIG. 3, the display unit 180 of the display apparatus 100 displays a screen including a first area and a second area (S200).

As illustrated in FIG. 4, the screen 300 displayed by the display apparatus 100 may be divided into a first area 301 and a second area 302, and may be divided into the first area 301. Content received from the server 10 may be displayed, and content input from a user of the display apparatus 100 may be displayed in the second area 302.

Accordingly, the display unit 180 displays the content received from the server 10 in the first area of the screen (step S210), and displays the content input through the user interface unit 190 in the second area of the screen. Display (S220).

By the content display method according to an embodiment of the present invention as described above, the user of the display device 100, which is an end user, inputs and edits content such as information or message to be delivered quickly and easily. can do.

For example, when the display apparatus 100 is installed in a restaurant for a digital signage system, the user directly applies a menu, phone number, price, and the like, which can be changed at any time, through the user interface 190 to display the screen. The second area 302 may be displayed.

According to an embodiment of the present invention, the content display of each of the divided first and second areas 301 and 302 of the screen 300 as described above is implemented in software or hardware. Can be.

On the other hand, the second area 302 can be set in a desired direction, such as up, down, left, and right, the user wants, the content displayed in the second area 302 is a variety of fonts (for example, style, size, color, underline style) , Effects, etc.) can be applied.

In addition, the displayed content may include various forms including emoticons and special characters, and may be positioned on the content without changing the size of the original background content in addition to a separate section.

For example, when implemented in software, the first area 301 of the screen 300 is the second area so that the media player 20 maintains the original aspect ratio, such as 16: 9, without altering the original. The version of the content in consideration of 302 may be delivered to the display apparatus 100.

Alternatively, when the media player 20 reduces the original image to fit the first area 301 in consideration of the second area 302, the corresponding content may be displayed in a deformed form.

Meanwhile, content displayed in the second area 302 may be displayed on the background image of the screen 300. In this case, an optimal visual function such as improvement of flicker may be considered by applying an overlay technique. . Alternatively, a method of outputting an emergency message on the screen 300 may be used.

In addition, when implemented in hardware, the first and second areas 301 and 302 of the screen 300 may be displayed by different display modules, respectively.

In the present specification, a module may mean a functional or structural combination of hardware for performing a technical idea and software for driving the hardware according to an embodiment of the present invention. For example, the module may mean a logical or functional unit of predetermined program code and a hardware resource for executing the program code, and does not necessarily mean physically connected program code or one kind of hardware.

When the content is displayed by object management, when the display apparatus 100 as a client receives the digital image content from the server 10, the information about the objects may be transmitted as separate metadata. have.

In this case, the metadata may be stored and managed in a DB of the display apparatus 100 and the server 10 with a unique ID value, and may include object information on a corresponding template as main information.

For example, the template object is distinguished and designated by a unique ID for each object at the time when the initial template is created through the server 10, and the corresponding information may be stored in the form of metadata. As a result, the object information can be checked and managed in the edit mode of the manager management program.

In addition, in an editing mode including object management of a template in the manager program, the metadata is variably configured, and caption information that can be frequently changed by the user is stored in the form of text and an image as necessary. And remote media data information.

In this case, the variably configured metadata may vary in size depending on a special scene, for example, a user input scene, which may require precise reliability in transmitting the message. have.

In particular, when the network is unstable and extremely low, when a large amount of multimedia data is included, packet loss may occur when a large number of clients are connected to the server and a message is sent at the same time.

Accordingly, before transmitting metadata, the display apparatus 100, which is a client, periodically sends a start message to the server 10, and the display apparatus 100 waits for a predetermined time before preparing the server 10. Ready) message can be transmitted if the message is normally received, thereby preventing other clients from transmitting data to the server 10 at the same time to increase the reliability of the message processing on the server 10 side do.

(2) Semantic Message: The client divides the message into semantic units when the metadata capacity exceeds a certain size (e.g., splits caption and multimedia data into other messages). Because it is divided into, the information can be utilized, it is easy to request retransmission, and the message loss probability can be reduced by reducing the size of the transmitted message.

On the other hand, the template ID (Template ID) is managed by the unique ID and the version (Version) of the template, and the server 10 does not retransmit only if both areas match.

In this case, when the exchange of template information between the server 10 and the display device 100 as a client is performed on-demand by an existing request / acknowledge, the server 10 changes the display device whenever the template is changed. It is required to request that the template exists, and the display apparatus 100 should take a response method through an Acknowledge message. In this general method, network communication is performed every time a template is changed, thereby increasing network traffic.

In order to minimize network traffic generated by the on-demand method, traffic usage can be minimized through the following procedure in which traffic is generated only when the template is updated due to user input on the client side. .

(1) On the client side, the user changes the content template currently being displayed.

(2) The server 10 sends template information (metadata) that is changed for user input.

(3) After confirming the transmitted meta information, the server 10 grants a new version for the case that matches the corresponding Template ID.

(4) The server 10 transmits the generated new Template ID / Version information to the client side again.

(5) The client stores the received template information in a local DB (Local Template List).

(6) The client sends the updated Local Template List to the client module.

(7) The updated Local Template List is transmitted to the server 10 side.

(8) The server 10 updates the list corresponding to the client by referring to the transmitted Local Template List.

(9) When the template sent to the client is changed, the list is checked to determine whether to transmit the template information to the client.

Accordingly, the transmission of metadata only occurs when the template is changed. If the client already has the data, the metadata is not retransmitted even if the template is changed.

On the other hand, in the display apparatus 100 on the client side, when the user wants to input or modify the desired information in addition to digital content transmitted unilaterally from the manager management program of the server 10, the display apparatus 100 is displayed in the display mode. You can switch to edit mode.

The information changed by the user is sent back to the manager management program of the server 10 in the form of metadata, and the manager program may transmit a unique digital image reflecting the metadata to the client.

If the user wants to periodically display specific information at a specific time, the user may be changed to predetermined information by date / time through a schedule management function.

In addition, the content edited by the user may be stored in the storage unit 170 of the display apparatus 100 for reuse.

In addition, by distinguishing the user mode (End User Mode) and the administrator mode (Admin User Mode), it is possible to limit the available functions according to the mode.

The content input by the user may be shared with other display devices through the server 10.

Hereinafter, embodiments of a method of dividing the display screen 300 to display content will be described in detail with reference to FIGS. 5 to 9.

Referring to FIG. 5, content received from the server 10 from the server 10 is displayed in the first area 301 of the screen 300 of the display apparatus 100, and the user interface is displayed in the second area 302. The content input from the user through the unit 190 may be displayed.

Referring to FIG. 6, a second area editable by a user, that is, a user input of content to be displayed by the user interface unit 190 may include a display module different from the first area 301, for example, an LED sign. Can be displayed.

An LED signboard is an all-signature sign board that displays characters using light-emitting diodes, and its lifespan is almost infinite compared to other light emitters (light bulbs, fluorescent lights, neon lights, etc.). Can be used. Display boards can be classified according to the type of diodes and controllers used. They are widely used as sign media.

In addition, the display board may be classified into a PC method and a remote control method according to the operation method, and generally, the remote control method may be convenient for a small display board (for example, 1 column or 10 columns or less), and for an on-demand or large display board The PC method may be convenient, or the second area 302 may be implemented by using the PC board and the remote controller.

For example, the remote control method can easily operate the remote control as a mobile phone toward the sensor attached to the electronic signboard, so that it can be conveniently used for indoor use or an electronic signboard installed on the 1st or 2nd floor. It may not be easy.

In addition, the PC-type display board is mainly convenient for a large display board or a display board installed a lot of distance and is operated by a program of a variety of display methods than the remote control method.

In this case, display modules displaying content in each of the first and second regions 301 and 302 may share a micom for controlling content reproduction.

Meanwhile, as shown in FIGS. 7 to 9, the position of the second region 302, for example, the position of the LED display board implementing the second region 302, is the first region as shown in FIG. 6. Not only the upper side of 301 but also the lower side, the left side, or the right side may be changed.

In this case, the position of the LED signboard may be fixed or manufactured, or may be removable at a location desired by the user.

On the other hand, the content display method may be stored in a computer-readable recording medium produced as a program for execution on a computer, and examples of the computer-readable recording medium are ROM, RAM, CD-ROM, magnetic tape, Floppy disks, optical data storage, and the like, and also include those implemented in the form of carrier waves (eg, transmission over the Internet).

The computer readable recording medium can be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the method can be easily inferred by programmers in the art to which the present invention belongs.
