Description

Content management method in interactive digital broadcasting system {METHOD FOR PROVIDING CONTENTS MANAGEMENT IN BIDIRECTIONAL DIGITAL BROADCASTING SYSTEM}

The present invention relates to a content service technology in an interactive digital broadcasting system. More particularly, the present invention relates to a two-way digital broadcasting system which is suitable for scraping and safely storing IP (Internet Protocol) content, editing and registering it, and allowing other users to view it. A content management method in a digital broadcasting system.

The present invention is derived from research conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy and ICT. [2008-S-006-01, Development of Open IPTV (IPTV 2.0) Technology for Wired and Wireless Environments]

Due to the development of digital technology, two-way digital broadcasting technology, which allows viewers to directly engage in broadcasting information, is widely used. A representative form of such two-way digital broadcasting is IPTV (Internet Protocol Television).

IPTV provides a variety of services such as channel broadcasting, video on demand (VOD), information provision, and T-commerce in both directions through a high-speed Internet (IP network) that guarantees quality, and is a set-top box. You can watch the program you want by connecting the high-speed internet network to the TV, not the PC monitor. The rapid spread of IPTV is due to the development of broadband and image compression technology of communication networks, which makes it possible to transmit high-definition video over IP networks.

By using such an IPTV, a user can not only listen to a broadcast similar to a conventional TV but also exchange information similar to the existing Internet and the existing Internet. In recent years, IPTV is expected to add not only simple TV programs but also various additional services such as voice, text, e-mail, and games.

On the other hand, for various service screens provided by IPTV, the user wants to express his or her opinion or knowledge and share it with others. In other words, in the general broadcasting system, because the channel number is assigned to each broadcasting company, only the broadcasting company can configure each channel. However, due to the activation of IPTV, viewers are separated from simply watching the broadcasting program. There is a need for a variety of viewer participatory management environments, such as operation and setup.

It is a business model that can increase the use of IPTV service by applying IPTV service so that users can scrape and edit the scenes of interest such as TV images to provide information to other users. .

Here, the scrap process should be easily performed for the scene desired by the user, and the contents should be stored in the set top box, and the editing process should be easily performed for the contents stored in the set top box when the user desires.

In addition, the scraped and edited content should be uploaded to the server so that other users can view it, and the scraping and editing process is preferably protected. For example, the original author information of the IPTV content should be kept intact, and the information of the user who performed the scraping and editing needs to be added.

The present invention is to provide a content management technology in the IP network to securely store the IP content, securely edit it, register it on a server, and allow other users to read it.

According to an embodiment of the present invention, a process of checking the validity of the client terminal in the content management server according to a content registration request from any client terminal of the client terminal group, and the validity check of the client terminal In the interactive digital broadcasting system comprising the step of allowing the scrap and editing of the content requested by the client terminal according to the result, and the content management server to register the scraped and edited content in the content database through the client terminal; Provide a content management method.

According to another embodiment of the present invention, there is provided a content management method in a two-way digital broadcasting system in which scraps and edited contents are stored by a client terminal group, the method comprising: from any client terminal in the client terminal group; Transmitting a content list of the scraped and edited contents from the content management server to the client terminal according to a content viewing request; and if the arbitrary content is selected from the transmitted content list by the client terminal, the content management. And a process of checking validity of the client terminal in a server and allowing viewing of content selected by the client terminal according to a result of validity test of the client terminal. do.

According to the present invention, a user can scrape and securely store contents in an IP network, for example, broadcast contents of an IPTV, and edit and register them in a server to provide a service environment where other users can read them. Content service usage in the IP network may be activated.

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

1 is a block diagram illustrating a service configuration of an interactive digital broadcasting system for implementing a content management method according to an embodiment of the present invention. The client terminal group 100, the IP network 102, the content management server 104, and client information are illustrated in FIG. DB 106 and content DB 108.

As shown in FIG. 1, the client terminal group 100 includes a plurality of client terminals for receiving a content management service, for example, a broadcast content management service of an IPTV, in an interactive digital broadcasting system applied to the present embodiment. (100/1 to 100 / N), and each of the client terminals 100/1 to 100 / N may be, for example, a set-top box for two-way digital broadcasting.

In this case, the client terminal 1 (100/1) in the client terminal group 100 may be a content registration client terminal that can scrape and edit any content at the request of the user, and the client terminal 2 (100/2) It may be a content viewing client terminal that can view the already registered content.

IP network 102 serves to support a communication environment between the client terminal group 100 and the content management server 104, for example, may be configured as a network using IP.

The IP network 102 is, for example, the Internet, and includes various services existing in the TCP / IP protocol and its upper layers, such as HyperText Transfer Protocol (HTTP), Telnet, File Transfer Protocol (FTP), and Domain Name (DNS). It refers to an open computer network structure that provides a System, Simple Mail Transfer Protocol (SMTP), Simple Network Management Protocol (SNMP), Network File Service (NFS), and Network Information Service (NIS). It provides an environment that allows any client terminal, for example client terminal 1 (100/1), to be connected to the content management server 104.

The content management server 104 is a subject that provides a content providing service, for example, a video on demand (VOD) service, a real time broadcasting service, etc. to the client terminal group 100 through the IP network 102, and the client information DB 106. , The content DB 108 and the like.

The content management server 104 according to the present embodiment, the client terminal 1 (100/1) in accordance with the content registration request from the content registration client terminal of the client terminal group 100, for example, client terminal 1 (100/1). When the client terminal 1 (100/1) is determined to be a legitimate client terminal by checking the legitimacy of the, the user terminal scraps and edits the corresponding content and stores (registers) the content in the content DB 108.

In addition, the content management server 104 stores the corresponding content stored in the content DB 108 in response to a content viewing request from the client terminal group 100 for viewing the contents of the client terminal, for example, client terminal 2 (100/2). (100/2) serves to enable viewing. In this case, since client terminal 2 (100/2) is a client terminal that may be related to simple viewing of content, the validity check on client terminal 2 (100/2) may be selectively performed.

The client information DB 106 stores client information managed by the content management server 104, for example, information such as ID, password, etc. for each client of the client terminal group 100. These information may be selected by the content management server 104.

The content DB 108 stores various content information managed by the content management server 104, for example, broadcast content information for IPTV broadcasting, and likewise, these broadcast content information may be selected by the content management server 104. There will be.

Such client information DB 106 and content DB 108 are, for example, relational database management systems (RDBMS) such as Oracle, Infomix, Sybase, DB2, or Gemston. The object-oriented database management system (OODBMS) such as Orion, O2, etc. may be implemented for the purpose of the present invention, and have appropriate fields to achieve its function.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figures 2 to 4 attached to the content management method in the interactive digital broadcasting system according to an embodiment of the present invention will be described in detail.

First, FIG. 2 illustrates a method of downloading personal safety information for secure IPTV content scraping and editing service from the content management server 104 in the content management method in the interactive digital broadcasting system according to the present embodiment.

As illustrated in FIG. 2, in step S200, any client terminal, for example, client terminal 1 (100/1) of the client terminal group 100, accesses the content management server 104 through the IP network 102. Sends a request message for requesting personal safety information.

In this case, the request message may include, for example, identification (ID) or password (password) information of the client. That is, for the request for personal safety information, the client terminal 1 (100/1) generates and stores a private key / public key pair for the purpose of electronic signature and encryption using the ID and password information of the client in advance, The request message for the information request may include the public key information of the client stored in the client terminal 1 (100/1). The request message for requesting the personal safety information may be encrypted and transmitted with the public key of the content management server 104.

Thereafter, the content management server 104 analyzes the request message transmitted from the client terminal 1 (100/1) (S202), and as a result of analyzing the request message, determines that the client of the client terminal 1 (100/1) is a legitimate client. Only in the case (S204), the personal safety information is transmitted to the client terminal 1 (100/1) (S206).

In this case, the validity determination of the client of the client terminal 1 (100/1) may be implemented by analyzing the ID or password of the user included in the request message.

In addition, the personal safety information transmitted from the content management server 104 to the client terminal 1 (100/1) is information used to prove that the client is the person who performed the IPTV content scraping and editing, and may be distinguished from other clients. It can consist of only one string that can be used. For example, the personal safety information may be transmitted by encrypting using the public key information of the user received in the above-described step (S200).

As such, the personal stability information transmitted from the content management server 104 to the client terminal 1 (100/1) may be stored on a storage medium in the client terminal 1 (100/1), for example, a hard disk drive. (S208). Here, since the personal safety information stored in the client terminal 1 (100/1) is encrypted, it can be obtained by decrypting with the private key of the client.

Meanwhile, FIG. 3 shows that the content management method in the interactive digital broadcasting system according to the present embodiment can scrape and edit any content according to a request of an arbitrary client terminal, for example, client terminal 1 (100/1). It is an example of a content registration service process.

As illustrated in FIG. 3, any client terminal of the client terminal group 100, for example, a client of client terminal 1 (100/1), requests content scrap for a desired scene while watching a VoD video or a real-time TV program. In the case (S300), the client terminal 1 (100/1) performs a scrap for the requested content, and stores the scrap results carried out on a storage medium, for example, a hard disk drive in the client terminal 1 (100/1) (S302).

At this time, the content scrap enforcement is characterized in that it is applied only when there is already stored personal safety information in the client terminal 1 (100/1), as described above in FIG.

Therefore, when the user executes the content scrap, the scene of a predetermined period (eg, time or frame) before and after the scrap execution time may be safely stored in the storage medium of the client terminal 1 (100/1). For example, the scene before and after the scrap execution time may be stored, for example, a scene 10 seconds after the scene 10 seconds before the scrap execution time, when the predetermined section is time. In order to store the scene before and after the user's desired point of time, the client terminal 1 (100/1) always temporarily records the scene before 10 seconds into the buffer, and when the client requests the scrap command, the content recorded in the buffer is temporarily recorded. It requires the process of saving.

In addition, when implementing content scraps using such personal safety information, for example, the original author information and personal safety information of IPTV content may be safely included, and the original author information and personal safety information are converted into tracking information and stored. Could be. In this case, the tracking information may be generated by signing information hashed by original author information, personal safety information, and scene image information with each user's private key for each scene to be stored.

Thereafter, in step S304, it is determined whether the editing of the content is requested from the client of the client terminal 1 (100/1), and if the editing of the content is requested, the client terminal 1 (100/1) loads the stored content. Content editing is performed (S306).

At this time, the content editing enforcement is applied only when there is already stored personal safety information, as in the above-described scrap trial and storage step (S302).

In this case, the original author information of the IPTV content and the personal safety information may be safely included in the content editing, for example, the original author information and the personal safety information may be converted into tracking information and stored. In this case, the tracking information may include the original author information and the personal safety information for each scene to be edited, and may be generated by signing the hash information of the original author information, the personal safety information, and the scene image information with the user's private key. .

When editing such content, the edit history of IPTV content can be converted into edit information, which is a list of strings, and stored safely. Such edit information is generated by listing a string containing the edit history of the user for each scene to be edited. The hashed information is generated by signing it with the user's private key.

The edited and stored content as described above may be illustrated as shown in FIGS. 4 and 5.

First, FIG. 4 illustrates a result of scraping and editing an arbitrary content provided through the IP network 102 on a TV screen, and a user edits one screen. It can be seen that three text information A, B, and C are inserted.

In addition, FIG. 5 illustrates a user's edit history as a string list (a, b, c).

Referring back to FIG. 3, in step S308, the content management server 104 determines whether content registration is requested from the client terminal 1 (100/1). That is, the client of the client terminal 1 (100/1) accesses or logs in to the content management server 104 through the IP network 102, and currently edits and stores the content in the client terminal 1 (100/1) (for example, FIG. It is determined whether registration of 4 screen information) is required. At this time, the content registration request, as in the above-described step (S302), characterized in that for transmitting the content that is securely edited and stored to the content management server 104, the information required for the content registration request includes tracking information and edit information May be included.

As a result of the determination in step S308, when the edited content registration is requested, the content management server 104 proceeds to step S310 to transfer the content requested by the client terminal 1 (100/1) to the content DB 108. Save it.

At this time, the content management server 104 is characterized in that it is determined whether the content is safely scraped and edited content. This determination may be implemented by examining the tracking information and the editing information generated in steps S302 and S306 described above.

Here, in the tracking information review, the original author information and the personal safety information of the user included in each scene in steps S302 and S306 are included in the content, and the original author information, the personal safety information, and the scene image information are included. The hashed information may correspond to the hash information included in the tracking information and may be respectively verified to be signed by the user's private key.

In addition, the editing information review includes a list of strings containing the user's edit history for each scene in step S306, and the edit details are signed with the user's private key without violating the content editing rules. It may include a process of confirming each.

In order to review such edit information, the content management server 104 stores a unique content editing rule for each content, which is specified by the content original author.

Through these processes, only the safely edited content may be stored in the content DB 108 to update the content list (S312).

On the other hand, Figure 6 is registered in the content DB 108 at the request of any client terminal, for example, client terminal 2 (100/2) in the content management method in the interactive digital broadcasting system according to the present embodiment. It illustrates an example of a content viewing service process that can view any content.

As illustrated in FIG. 6, when the client terminal 2 (100/2) accesses the content management server 104 through the IP network 102 and requests a content list stored in the content DB 108 (S400), the content The management server 104 transmits the requested content list to the client terminal 2 (100/2) (S402).

Thereafter, when the client terminal 2 (100/2) selects arbitrary content and requests to view the content (S404), the content management server 104 proceeds to step S406, where the client terminal 2 (100/2) is legitimate. The client determines whether the personal safety information is stored in the client terminal 2 (100/2) based on a result of analyzing the personal safety information request message. Here, the personal stability information request message may include an ID, a password, and the like of the client of the client terminal 2 (100/2) as described above.

In this case, since the client terminal 2 (100/2) is a client terminal that may be related to the simple reading of the content, such a validity check on the client terminal 2 (100/2) may be selectively performed.

As a result of the determination in step S406, when it is determined that the client terminal 2 (100/2) is a legitimate client, the content management server 104 proceeds to step S408 and the client terminal 2 (100/2). Allows viewing of the selected content.

As described above, according to the present embodiment, the contents of the IP network, for example, broadcast contents of the IPTV, can be scraped and stored safely by the user, and edited and registered in the server so that other users can read them. It is an implementation of content service activation in the same IP network.
