More particularly, the present invention relates to receiving a content to be delivered to a user according to a user's request or setting, and to recording or recording a corresponding channel and program content. The present invention relates to a personalized video service system for controlling playback.

With the development of technology, the recent broadcasting environment is changing rapidly from analog broadcasting to digital broadcasting, diversified broadcasting media, interworking with wired and wireless communication networks, and high-performance broadcasting terminals.

In particular, recently, IPTV has been an issue, and this IPTV is a TV service that can receive digital multimedia contents such as broadcasting channels, VOD, life information, education, and games through an internet communication network. Existing broadcast services and various interactive additional services can be used. Examples include program performer and shooting location information, player and score information of a sports event, more detailed information in advertisements, EPG services, and the like.

In the conventional two-way digital broadcasting, a method of using a smart card inserted in a CAS (Conditional Access System) and a user terminal (IP set-top box) for controlling the channel receiving authority of the individual has become common.

However, this method is a channel-based receiving authority control system, which does not provide a method for judging and controlling reception based on the contents of each channel centered on individual users, as well as remote PCs and mobile phones. Etc., the terminal connected to the network cannot check the contents of the broadcast content being viewed in the home and control the viewing.

Therefore, when the parental authority manages and supervises the child's TV watching, the desire to determine and control the child's viewing by the content constituting the channel and the desire to check the child's TV viewing history (viewing time and watched content), etc. Not only do they fail to meet this requirement, but these needs cannot be realized in remote locations in real time.

An object of the present invention for solving the above-described problem is to determine the receiving authority according to the user's request or setting content delivered to the user and to control whether or not to record or play the corresponding channel and program content. .

In addition, an object of the present invention is to enable the user (parent) to immediately check the child's viewing history and viewing content in a remote place in real time to control whether or not the child watching the corresponding broadcast.

Personalized video service system of the present invention for achieving the above object is a user information DB for storing user information including user information and viewing authority information provided from the user; An EPG storage unit for storing user-specific EPGs and EPGs received from broadcasters; An interface unit configured to generate a user interface for receiving the viewing authority information from the user based on the EPG, provide the user interface to the user terminal, and store the viewing authority information received through the user interface in the user information DB; A rights management unit which generates the user-specific EPG using the viewing authority information and the EPG and stores the EPG for each user and stores the EPG in the EPG storage unit; And an EPG management unit which extracts the EPG for each user from the EPG storage unit and transmits the EPG to the user terminal at the request of the user terminal.

A method of providing a personalized video service according to the present invention may include a first step of generating a user interface using an EPG provided from a broadcasting company; A second step of receiving the viewing authority information by providing the user interface to the user terminal according to the viewing authority control request from the user; A third step of generating a user-specific EPG using the provided viewing authority information and the EPG; And a fourth step of transmitting the user-specific EPG to the user terminal at the request of the user terminal.

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

The user terminals 11, 12, and 13 are apparatuses for using a bidirectional broadcasting service, and generally include digital TVs, IP set-top boxes, PCs, and mobile phones. The user terminals 11, 12, and 13 receive content provided by the broadcaster 30 according to a user's request and display the content on the screen, and a user response signal input from the user through a remote controller, a PC mouse, or a button on the terminal. To the broadcaster 30. In particular, when the user terminals 11, 12, and 13 in the present invention receive a request for content viewing authority control (registration / change / deletion, etc.) from a user (master user), the user terminal 11, 12, 13 is connected with a personalized video service system 20 to view viewing authority The user interface for the control is displayed on the screen to receive necessary information (viewing authority information) and transmit it to the personalized video service system 20, and receives and stores the user-specific EPG from the personalized video service system 20. In this case, as a method for controlling viewing authority, the user may select contents (or contents not desired to be viewed) among contents of the EPG using EPG provided by the broadcaster 30. Alternatively, a separate user interface (UI) may be used for personalized service. When the user logged in using the identification information requests to view the content, the user terminals 11, 12, and 13 compare the content information requested by the user with the individual EPG provided to the personalized video service system 20 to view the content. The content is played only if the content is allowed, and if not, a message indicating that the viewer cannot be viewed is displayed on the screen.

The personalized video service system 20 receives and stores an EPG from the broadcasting company 30, and receives the viewing right information and the broadcasting company provided through the user terminals 11, 12, and 13 according to the user's viewing right control request. The EPG generated by the user is generated using the EPG provided from 30), and the user-specific EPG generated according to the user's request is provided to the corresponding user terminals 11, 12, and 13. The user-specific EPG is updated whenever the content viewing authority is newly set according to the user's viewing authority control request. In the present invention, a user is divided into a master user and a slave user, wherein the master user is a representative user who is subscribed to the broadcast service provided by the broadcaster 30, and creates a slave user and creates a slave user. A user who can set (control) the user's content viewing authority. For example, a master user can be the parent of a family, a slave user can be a child registered by a parent, and a master user and a slave user are assigned different identifiers to distinguish their rights.

The broadcaster 30 provides the EPG to the personalized video service system 20 as a broadcast content provider and provides the content requested from the user terminals 11, 12, and 13 to the user terminal through the personalized video service system 20. 11, 12, 13).

The wired / wireless data network transmits contents provided by the broadcaster 30 to the user terminals 11, 12, and 13, and viewing authority between the user terminals 11, 12, and 13 and the personalized video service system 20. As a network for data transmission related to control, wired and wireless Internet (IP network), cable network, public telephone network (PSTN), mobile communication network (for example, CDMA (Code Division Multiple Access), WiFi (Wireless Fidelity), WiBro (Wireless Broadband Internet) ), HSDPA (High Speed Downlink Packet Access), and the like.

FIG. 2 is a diagram illustrating in more detail the configuration of the personalized video service system 20 of FIG. 1.

The personalized video service system 20 of the present invention includes a user information DB 21, an EPG storage unit 22, an interface unit 23, an authority processing unit 24, and an EPG management unit 25.

The user information DB 21 stores user information including user information provided when a user subscribes to a service and viewing authority information provided from a master user for controlling viewing authority for a slave user. For example, the user information DB 21 stores identification information for each user, user terminal information for each user, viewing authority information for slave users, and the like. In this case, the viewing authority information may be matched and stored with information about the slave user who is not allowed to view the contents of the EPG.

The EPG storage unit 22 stores the EPG provided from the broadcaster 30 and the EPG for each user generated according to the viewing authority information set by the master user.

The interface unit 23 generates a user interface for viewing authority control using the EPG provided from the broadcaster 30 and provides the user interface to the user terminals 11, 12, 13, and the user terminal 11, 12, The viewing authority information provided from 13 is stored in the user information DB 21. At this time, when the interface 23 receives a request for viewing permission from the user, the interface 23 compares the identification information used when the user logs in to control the viewing authority with the user information of the user information DB 21 to determine whether the corresponding user is the master user. By authenticating, only the master user can control viewing rights. When the EPG is newly supplied from the broadcaster 30, the interface unit 23 notifies the EPG change to a terminal of a predetermined user and informs the viewer to change the viewing authority information according to the changed EPG. In addition, the interface unit 23 informs information on which slave user among the slave users registered by the master user is currently logged in and watching the content at the request of the master user. Using this function, the master user can check which children are watching the content in the home using the mobile communication terminal 13 at a remote location.

If the right processing unit 24 receives the viewing authority information from the user terminals 11, 12, and 13 through the interface unit 23, the rights processing unit 24 uses the received viewing authority information and the EPG stored in the EPG storage unit 22. After generating the update of the user-specific EPG of the EPG storage unit 22 (new registration / modification / deletion). That is, the authority processing unit 24 collects information on the contents of the EPG contents which are allowed to be viewed by each slave user, generates an EPG for each individual slave user as an EPG for each user, and then stores the information in the EPG storage unit 22. Save or change.

The EPG management unit 25 transmits the user-specific EPG stored in the EPG storage unit 22 to the corresponding user terminals 11, 12, 13 according to a request of the user terminals 11, 12, 13. At this time, the request from the user terminal 11, 12, 13 is when the user terminal 11, 12, 13 requests the user-specific EPG for the user when the user requests to view the content or the master user to a specific terminal There may be a case where a request for transmission of.

3 is a flowchart illustrating a method of controlling viewing authority by using the personalized video service system 20 of the present invention.

First, a method of controlling viewing authority under the premise that master users and slave users who want to use the video service of the present invention online or offline in the personalized video service system 20 are registered.

When the interface unit 23 of the personalized video service system 20 receives the EPG including the channel schedule and content details from the broadcaster 30, the interface unit 23 stores the EPG in the EPG storage unit 22 (step 301).

Here, the EPG is additionally provided by the channel name, channel personality, program name, program genre, program performer, viewing age, adult broadcasting, broadcasting time, recording availability, downloadability, content price, broadcasting language, and service provider. Contains the details you want to say.

When the EPG is newly received from the broadcaster 30, the interface unit 23 of the personalized video service system 20 allows the user (master user) to set viewing rights for each item of the provided EPG. Generates (step 302).

In this case, in generating a user interface, the interface unit 23 may set a viewing authority for each slave user for each of all contents, but the user may quickly and easily view viewing rights for a large number of contents. In order to set the contents, the master user is divided into a group, for example, a channel unit, a program genre unit, a program name unit, a viewing age unit, a program personality (violence, romance, etc.) unit, a broadcasting time unit, a content price unit, and the like. The user interface can be configured so that the viewing authority can be collectively set in the group unit satisfying a specific condition. For example, if the master user is a parent and the slave user is a child, all the content broadcasted by a parent on a specific channel, all content over a certain price (for example, 2,000 won), all content of a specific genre or personality such as violence / adult / cartoon The user interface is generated and provided to the user terminals 11, 12, and 13 so that the user can edit the content reproduction authority according to a specific situation that may occur for each individual, such as when the child does not want to watch.

Alternatively, the broadcaster 30 may generate and provide a content receiving authority setting template in order to solve the inconvenience of a user who has to specify a use authority for a large number of contents. For example, for a master user (e.g. a parent) who wants a slave user (e.g. a child) to watch only channels and programs related to education, the slave user can only play in batches on the education channel and a program related to education. , And create and provide an "Education Channel Only" template that sets permissions to disable playback of other content in batches, the parent user can simply choose the "Education Channel Only" template You can quickly and easily set permissions for receiving content.

Next, when the master user logs in to the user terminals 11, 12, and 13 and selects a specific menu for viewing authority control, that is, newly registering the viewing authority or correcting or deleting the previously registered viewing authority, the user terminal ( 11, 12, and 13 transmit a viewing authority control request signal to the personalized video service system 20, and transmit user information (identification information) of the corresponding user (step 303).

When the viewing authority control request signal is received from the user terminals 11, 12, and 13, the interface unit 23 stores the user information (identification information) received together with the viewing authority control request signal in the user information DB 21. It is checked whether the user subscribes to the service and the master user by comparing with the information (step 304).

If the authentication is normally completed, that is, the user is confirmed as a normal master user, the interface unit 23 transmits the user interface generated in step 302 to the corresponding user terminals 11, 12, 13, and the user terminals 11, 12,. The user interface is displayed on the screen of step 13) (step 305).

The user sets viewing authority for each slave user registered through the user interface displayed on the user terminals 11, 12, and 13.

When the viewing authority setting by the user is completed, the user terminals 11, 12, and 13 transmit the viewing authority information input by the user to the personalized video service system 20 (step 306).

The authority processing unit 24 of the personalized video service system 20 that receives the viewing authority information generates an EPG for each user using the received viewing authority information and the EPG stored in the EPG storage unit 22, and then the EPG storage unit ( The user-specific EPG stored in 22) is updated (new registration / modification / deletion) (step 307).

To this end, the authority processing unit 24 first sets a viewing authority for each content for each content constituting the EPG, and then uses it to generate an EPG for each user whose viewing authority is indicated. That is, the authority processing unit 24 collects information on the contents of which the viewing is allowed among the contents of the EPG for each user and generates an individual EPG. If the user-specific EPG for the user is not in the EPG storage unit 22, the newly registered and stored user is changed. If there is already, the user-specific EPG is changed to the newly created user-specific EPG.

Subsequently, when the user logs in to his user terminal 11 to watch TV, selects a desired content, and requests playback (viewing) of the corresponding content (step 308), the user terminal 11 transmits to the user. The user information is transmitted to the personalized video service system 20, and a user-specific EPG for the user is requested (step 309).

Then, the interface unit 23 of the personalized video service system 20 first checks whether the corresponding user is a master user or a slave user using user information. In this case, when the corresponding user is a master user, the interface unit 23 transmits a signal (master notification signal) indicating to the user terminal 11 that the corresponding user is not a viewing authority control target as the master user. However, when the corresponding user is a slave user, the interface unit 23 transmits identification information of the corresponding user to the EPG management unit 25.

Accordingly, the EPG management unit 25 extracts the user-specific EPG from the EPG storage unit 22 using the identification information provided from the interface unit 23 and then uses the user-specific EPG through the interface unit 23. Transmission to the terminal 11 (steps 310 and 311).

In response to the request of step 309, when the user-specific EPG is received from the personalized video service system 20, the user terminal 11 compares the content requested by the user with the received user-specific EPG to display the requested content. The content is played only when the content is allowed to be viewed (step 312).

If the corresponding content is content for which viewing is not allowed, the user terminal 11 displays a message indicating that the viewing cannot be performed on the screen and does not perform a playback operation on the corresponding content. The determination of viewing authority for the content requested to be viewed is repeatedly performed whenever the content requested for playback is changed, such as a user changing a channel.

However, since the above-described viewing authority control and content playback are not performed only at the same user terminal, while the slave user is watching the content through the TV in the snack bar, the master user uses the other user terminal 13 at the remote location. Viewing authority control can be performed. For example, the master user may check the user-specific EPG set in the EPG storage unit 22 using his mobile communication terminal 13 while moving and update the same through the above-described viewing authority control method. In addition, the master user requests the personalized video service system 20 to transmit the updated user-specific EPG to the terminal 11 in his or her own, and transmits the user-specific EPG previously transmitted to the user terminal 11. You can change to this newly updated user-specific EPG.

As such, the user-specific EPG can be changed while the user (slave user) is watching the content. Accordingly, the user terminal 11 compares the content information currently being played with the EPG for each user periodically (for example, at five minute intervals) even while playing the content, and checks whether the corresponding content is the content that is allowed to be viewed. . If the viewing authority for the content currently being played is changed from viewable to viewable, the user terminal 11 stops playing the content and displays a message indicating that the change has been made impossible to view.

In an IPTV environment, playback can be performed using the Internet Group Management Protocol (IGMP). If there is no receiving authority, IGMP Leave packets can be sent to immediately block the reception of IPTV multicasting packets. Multicasting is used for channel-based IPTV streaming in real time, and in case of IP-based VOD service, it can block reception by transmitting a Teardown message of RTSP (Real Time Stream Protocol).

When the master notification signal is received from the personalized video service system 20 in step 312, the user terminal 11 does not perform the viewing authority determination for the user, but performs the playback operation on the content requested by the user as in the prior art. do.

As described above, the personalized video service system of the present invention can increase the convenience of the viewing environment by setting and updating the EPG for each user, and controls the viewing authority of the content based on various additional information on the EPG. By allowing viewing rights to be controlled remotely, parental viewing rights can be controlled more effectively.

In addition, the present invention can analyze the customer demand according to the user's request to control the viewing rights of the program and use it to secure the content and quickly grasp the customer's propensity to provide related services (EPG, VOD service, etc.) It is effective in increasing gender and increasing sales of related services.

In addition, the present invention provides the Internet as well as TV, Code Division Multiple Access (CDMA) network, Wireless Fidelity (WiFi) network, Wireless Broadband Internet (WiBro), High Speed Downlink Packet (HSDPA). Access) network and digital multimedia broadcasting (DMB) in conjunction with the service can control the rights to view the content provided by the operator anytime, anywhere, it is effective to link the service.
