Description

METHOD AND APPARATUS FOR PROVIDING CONTENTS SYNCHRONIZATION ON NETWORK, CONTENTS MANAGEMENT SERVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for synchronizing contents information, and in particular, by synchronizing contents and contents information by utilizing contents information and IP (Internet Protocol) information between a control terminal and a server. A method and apparatus for synchronizing content on a network suitable for efficiently utilizing resources, and a content management server therefor.

Currently, advertisements and guide boards installed on roads or outdoors are changing from a management method using a fixed display to a method managed by a digital system and updated.

To this end, a system for controlling a Liquid Crystal Display (LCD) / Light Emitting Diode (LED) display board is generally constructed, and the contents necessary for the system are directly offline by the administrator. It is mainly used to update through a card, or to establish a LAN (Local Area Network) to control from a central server. Recently, management using a wireless LAN or Bluetooth is possible to manage wirelessly. New systems are being developed.

The most common way to advertise content is for administrators to upgrade directly from offline via memory cards, which is not only inferior in terms of immediateness, but also disappears due to inefficiencies in management. In general, the trend is to establish a LAN, such as a wire-based system controlled by a central server.

However, the wire-based method is a method that can be used only in a building or a city center, and is not available outside the city where the internet network is difficult to access. In addition, there is a disadvantage in that the cost required for the construction and management of the wired network is high. Nevertheless, the trend is widespread due to the advantages of stability and central management.

In order to improve the problems of the wired-based method, a method for managing and updating wirelessly has been recently proposed, but there are limitations in the use distance because most of them use a short-range wireless communication technology such as wireless LAN or Bluetooth. In addition, the advertisement billboard operating techniques using a wireless network using a broadband wireless communication network such as CDMA are often inefficient in the actual wireless environment because content synchronization and management are made by using the existing wire management method.

That is, in the existing wireless signboard control technique, the control terminal needs to check whether or not to update the central server in order to check whether the content is updated from time to time, and transmits the content from the central server to each control terminal at the same time. In most cases, even if each content is transmitted individually, the content is inevitably transmitted based on the history stored in the server.

These technical limitations result in a waste of expensive radio sections by increasing unnecessary traffic in radio sections, and all the control terminals have to control the same at the same time, and there is no transmission error, terminal reset, or network. There is a problem that a synchronization error is likely to occur because the update by a memory card or the like cannot be automatically reflected.

Accordingly, in the present invention, in synchronizing and managing the content inside the control terminal distributed in a remote location, information about the content is collected between the central server and the control terminal so as to utilize the relatively expensive and slow radio resources as efficiently as possible. The present invention proposes a procedure for transmitting and receiving and a technical method for receiving and executing the same.

According to one aspect for solving the problems of the present invention, connected by a network to transmit information about any content and Internet protocol address information, and based on the information of the content when the updated content and the information of the content is received At least one control terminal for updating its own content, and temporarily storing information of the content transmitted from the at least one control terminal and Internet protocol address information, and controlling the at least one control according to whether the information of the content is changed. Provided is a content synchronization device on a network including a content management server for transmitting updated content and information of content to a terminal.

According to an embodiment of another aspect for solving the problems of the present invention, a content synchronization method for managing a content database and a synchronization information database via a network, the information of the content of the control terminal and the Internet protocol address information through the network Storing the received content information and Internet protocol address information in a synchronization information database, comparing the information of the content stored in the synchronization information database with the information of the original content stored in the content database; And transmitting the updated contents and the information of the contents to the control terminal according to the result of the comparing process.

According to another embodiment of another aspect for solving the problems of the present invention, a method of synchronizing contents of a control terminal on a network comprising the steps of: transmitting information of content and Internet protocol address information to a server connected by the network; When the updated content and the information of the content is received from the server, it provides a content synchronization method on the network comprising the step of synchronizing the content of the control terminal with the received updated content and the information of the content.

According to another aspect for solving the problems of the present invention, the storage means for temporarily storing the information and the Internet protocol address information of the content transmitted from the at least one control terminal over the network, and the information of the content stored in the storage means and After comparing the information of the original content and provides a content management server including the updated content and the transmission means for transmitting the information of the updated content to the at least one control terminal according to the comparison result.

According to the present invention, contents and content information are synchronized using contents information and IP (Internet Protocol) information between a control terminal and a server, and content to be updated from the server to each terminal only when the contents are updated. By transmitting, unnecessary traffic overhead on the network can be reduced. In addition, when updating contents, it is possible to reduce the probability of synchronization error by supporting an update environment using a memory card or the like as well as wireless and adding an acknowledgment procedure when the update is completed.

Will be. Of course, the broadband wireless communication network is not limited thereto, and may include a GSM network other than a CDMA network and an access network of all mobile communication systems to be implemented in the future.

On the other hand, the content management server 104 according to the present embodiment is the information of the content from any control terminal of the control terminal group 100, for example, control terminal 1 (100/1) through the network 102 described above. And IP address information, and temporarily stores the transferred content information and IP address information in the synchronization information DB 106. In addition, the content management server 104 compares the information of the content stored in the synchronization information DB 106 and the information of the original content stored in the content DB 108 to compare the updated content and the information of the content if they do not match with each other. It serves to deliver to the control terminal 1 (100/1) through the network (102).

In this case, although the content management server 104 is illustrated as being separated from the synchronization information DB 106 and the content DB 108, this is only for convenience of description and synchronization information in the content management server 104. Those skilled in the art will readily appreciate that the DB 106 and the content DB 108 may be configured to be included.

In addition, the content management server 104, in order to receive the information and IP address information of the content from the control terminal group 100 through the network 102, or to deliver the content and the information of the content to the control terminal group 100 A separate network transmission means (not shown) may be provided, and the technical means can be easily understood by those of ordinary skill in the art, and a detailed description thereof will be omitted.

In the synchronization information DB 106, information of contents held by any control terminal of the control terminal group 100, for example, control terminal 1 (100/1), and IP address information of the control terminal 1 (100/1) are temporarily stored. Can be stored.

The content DB 108 may store a plurality of original contents, information of each content, such as the type of each content, state information of each content, and the like. Here, the state information of each content may include, for example, a unique number for each content, a last update time of the content, and the like.

The synchronization information DB 106 and the content DB 108 are managed by the content management server 104, and the relational database management system (Oracle, Infomix, Sybase, DB2) RDBMS, or object-oriented database management system (OODBMS) such as Gemston, Orion, O2, etc. can be implemented for the purposes of the present invention, and suitable fields ( fields).

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figures 2 and 3 attached to the content synchronization method on the network according to an embodiment of the present invention will be described in detail.

First, FIG. 2 is a flowchart illustrating a content synchronization method on a network according to the present embodiment, in particular, a content synchronization process centered on the content management server 104.

As illustrated in FIG. 2, in step S200, the content management server 104 is connected from any control terminal of the control terminal group 100, for example, control terminal 1 (100/1), via the network 102. It is determined whether the content information and the IP address information are transmitted.

When content information and IP address information are transmitted from the control terminal 1 (100/1), the content management server 104 temporarily stores the transmitted content information and IP address information in the synchronization information DB 106 (S202).

Thereafter, the content management server 104 retrieves the content information (A) from the content information and the IP address information temporarily stored in the synchronization information DB 106, and then stores the content information (A) and the original stored in the content DB 108. Content information B of contents is compared (S204).

As a result of this comparison, when the content information A stored in the synchronization information DB 106 and the content information B stored in the content DB 108 do not match (S206), the content management server 104 performs step S208. The controller 100 transmits the updated content and the information of the content, that is, the last updated content and the information of the corresponding content stored in the content DB 108 to the control terminal 1 (100/1).

Thereafter, the content management server 104 sends an update completion message from the control terminal 1 (100/1) via the network 102, that is, when the control terminal 1 (100/1) completes an update on its content. It is determined whether the message is transmitted (S210), and if the update complete message is transmitted, the content management server 104 proceeds to step S212.

In step S212, the content management server 104 updates the DB for the terminal. For example, the information of the content of the control terminal 1 (100/1) stored in the synchronization information DB 106 is changed to the last updated information.

These processes can be repeated continuously if the content synchronization service is being activated.

Meanwhile, in the description of the above-described embodiment, the information stored in the synchronization information DB 106, for example, the status information of the content, may be exemplified as shown in the following [Table 1] using the unique number of the corresponding content as the primary key. There will be.

FIELD NAME DESCRIPTION TYPE & LENGTH Contents Number For each content
Unique number BINARY (48) Control Terminal IP IP of the control terminal where the content exists BINARY (32) Last update Last modified date DATE

As exemplified in [Table 1], the information stored in the synchronization information DB 106 is, for example, the unique number of the content held by the control terminal 1 (100/1), IP address information, and final information on the content. Modification date (update time) may be included.

In addition, information stored in the content DB 108, for example, state information of the content, may be illustrated as shown in Table 2 below.

FIELD NAME DESCRIPTION TYPE & LENGTH Contents Number For each content
Unique number BINARY (48) Contents Name The name of the content STRENTH (60) Contents Address Address of the server where the content is located BINARY (32) Last update Last modified date DATE Contents Type Type of content STRENGTH (60) OPTION Other information <OPTIONAL>

As illustrated in [Table 2], the information stored in the content DB 108 is, for example, the unique number of the content held by the control terminal 1 (100/1), the name of the corresponding content, the server where the corresponding content is located. It may include the address of, the last modified date of the content (update time), the type of content, and various other information.

As can be seen from Table 1 and Table 2, the information stored in the synchronization information DB 106 has a relatively small DB capacity compared to the information stored in the content DB 108. Due to this, when searching for information and updating information through the synchronization information DB 106, the search load may be minimized.

On the other hand, FIG. 3 illustrates a content synchronization method on a network according to the present embodiment, in particular, a content synchronization process centering on an arbitrary control terminal of the control terminal group 100, for example, control terminal 1 (100/1). A flowchart is shown.

As illustrated in FIG. 3, in step S300, the control terminal 1 (100/1) transmits information of its content and IP address information to the content management server 104 through the network 102.

Thereafter, the control terminal 1 (100/1) determines whether the updated content and the content information are received from the content management server 104 (S302). When the updated content and the information of the content are received, the control terminal 1 ( 100/1) proceeds to step S304. At this time, the updated content and the information of the content means that the information of the content stored in the above-described synchronization information DB 106 and the information of the content stored in the content DB 108 do not coincide with the control terminal 1 (100/1). This may mean information for updating the content and the information of the content.

In step S304, the control terminal 1 100/1 newly updates the content and the content information stored in the control terminal 1 100/1 based on the received updated content and the information of the content.

When the update of such content and information of the content is completed (S306), the control terminal 1 (100/1) proceeds to step S308 and a predetermined update completion message, for example, "the content and information about the content of the content". The update is completed. ”Is transmitted to the content management server 104.

As described above, according to the present embodiment, by synchronizing the content and the content information by utilizing the content information and IP information between the control terminal and the server, and transmitting the content to be updated from the server to each terminal only when the content is updated, It is implemented to reduce unnecessary traffic overhead.

The foregoing embodiments are intended to illustrate, not limit, the invention, and those skilled in the art should note that many other embodiments can be designed without departing from the scope of the invention as defined by the appended claims. do. In the claims, any reference signs placed between parentheses shall not be construed to limit the invention.
