Each connected digital signage device shall be capable of combining or connecting to various sizes and irregular sizes according to the user's intention. When a user / content event, for example, a touch, is generated for each digital signage device, the same event should be transmitted to the other digital signage device so that it can respond accordingly. In addition, smooth content reproduction must be possible without time difference in content loading and rendering for each digital signage device.

5 is a diagram for explaining a synchronization problem in a multi-browser environment based on a digital signage apparatus in a synchronization system according to an exemplary embodiment.

The synchronization system may provide digital signage services through operations between a content server 510, a synchronization manager 520, and a digital signage device 530. Synchronization system may cause issues related to synchronization of events and rendering between browsers operating in an independent operating system based environment. Accordingly, it is necessary to transmit an event to each device as an event is input from a user in a different browser. In addition, when the inter-screen rendering of the digital signage apparatus 530 is performed, synchronization issues may occur according to the following factors. Synchronization issues can occur depending on network conditions, in other words, bandwidth and process state. There may be a time difference in content loading by digital signage device. At this time, the digital signage apparatus may not be updated at the same time, resulting in a sense of heterogeneity. For example, a digital signage device may be loaded from the upper left to the lower right in the case of image loading. Also, the digital signage apparatus may cause a difference in rendering timing depending on the CG or the like. For example, a screen flicker or an inconsistency of exposure of contents may occur depending on the update of each screen of the digital signage apparatus.

The synchronization system can be preset to provide functions of virtual screen setting, connection URL designation, compatibility test, and linkage performance test for connecting to a plurality of digital signage devices for web browsing. The synchronization system can preset the digital signage device's setting function, network setting function and event setting function.

The setting function of the digital signage device may include a virtual resolution setting function, a physical structure setting function, and an interlocking test function. The virtual resolution setting function can set the virtual resolution of the connected digital signage device and can be omitted depending on the requirements or development structure. The physical structure setting function can manage the physical location and identification data for each digital signage device, and the interlocking test function can mean the network, response delay setting and correction function for each digital signage device. For example, if the overall response speed is slow, it is recommended to disable the function such as scrolling.

The network setting function may include a network link setting function with the digital signage device and a function of setting a representative URL for connection with the content provider. The event setting function may include an event recognition setting for interaction with the user from the digital signage device. For example, it is possible to control a user's reaction according to whether or not the device, screen, and contents function are supported.

8 is a flowchart illustrating a synchronization method of an independent digital signage apparatus in a synchronization system according to an exemplary embodiment.

The synchronization system can perform synchronization through operation with the content provider 810, the synchronization manager 820 and the plurality of digital signage devices 830, and can provide multiple independent digital signage services.

The synchronization system can set the virtual resolution of the generated group, set the screen information of the connected digital signage device, set the reaction event, set the target URL of the group, and set the power time of the screen. The synchronization system may set individual identification data for each screen of the digital signage device and register the location of the physical screen based on the virtual resolution. At this time, since the screen-specific sizes may be the same or non-uniform, input functions for the size of the physical screen must be separately provided for them. The synchronization system can set a reaction event by setting whether or not the group reacts to an event, and setting a reaction event for each screen of the digital signage device. The synchronization system can set the target URL of the group by setting the content loading URL. The synchronization system can set the on / off time of the screen through the screen control function of non-operating time.

The synchronization system may set the identification data and the physical location of the digital signage device (630). The synchronization system may provide identification data to the digital signage device to which the connection is requested and establish a physical location relative to the virtual screen as a connection is requested from the screen of each digital signage device.

The synchronization system may prepare (640) the synchronization process of the digital signage device and proceed to the synchronization process as the synchronization process is ready (650). The synchronization system may set the correction value based on the result of performing the synchronization (660). The synchronization system can be set based on the result value according to the progress of the synchronization process or can provide the function that the administrator can modify to a certain value.

The synchronization system may set 670 the content page to be actually loaded from the digital signage device of the connected group. The synchronization system may request a connection from each digital signage device (680). The synchronization system may initiate a digital signage service (690) upon completion of connection requests and rendering from all digital signage devices included in the group.

The synchronization system can measure HTTP based Response Delay. The synchronization system may, for example, perform per-URL or per-content measurements. For example, the synchronization system can measure the response delay through Method, Status, Type, Size (Content Size), and Time (Latency).

The synchronization system may begin the synchronization process as registration from the digital signage device is completed (700). The synchronization system may be requested 710 for a Test URL connection from each digital signage device. At this time, the digital signage device can access the test URL separately provided on the CMS or the synchronization manager.
