The present invention relates to a TV broadcast channel limiting system and a method thereof, and more particularly, home management (RG) in each home equipped with a TV broadcast reception (aka set-top box) function and home management for remotely managing the home gateway. In a home network composed of a server (HOMS), a home channel for registering broadcast channel information designated by a subscriber to a home management server and filtering broadcast data transmitted and received at the home gateway through a data sync with the home management server A system and method for limiting TV broadcast channels in a network.

Recent advances in digital technology have made it possible for subscribers to watch digital broadcasts on television. For example, IP-TV (Internet Protocol-televison) broadcasting service is a TV connected to an IP-based communication network and provides various contents (air / wired TV broadcasting, movies, music, interactive quiz shows, TV banking, etc.). Say. As another example, a digital cable TV broadcasting service refers to a service that provides interactive content (airwave / wired TV broadcasting, goods purchase, stock trading, etc.) to a TV connected to a wired cable network digitally.

In the IP-TV broadcasting service, a TV is connected to a set-top box (STB) equipped with an Internet connection function in the home (subscriber side), and a subscriber is provided to the IP-TV broadcasting service provider for viewing. The head-end is configured to transmit the selected content (eg, SBS golf broadcast data corresponding to channel 41) to the set-top box of the home.

In addition, when looking at the digital cable TV broadcasting service, a TV is connected to a set-top box connected to a wired cable network in the home (subscriber side), and the content selected by the subscriber for channel viewing is provided to the digital cable TV broadcasting service provider. For example, a head-end for transmitting SBS golf broadcast data corresponding to channel 41 to a set-top box in a home is configured.

The above-mentioned IP-TV broadcasting service and digital cable TV broadcasting service differ only in whether the set-top box installed in the home has internet access function and communication network for providing service. Not only do they feel at all, they are perceived to be provided with the same interactive service, and the process for providing each TV broadcast service is the same.

For example, if the subscriber selects channel 69 by operating the remote controller for viewing the adult broadcast, the set-top box transmits the subscriber's request (channel 69 request signal) to the corresponding headend. Then, the headend asks for a password input for adult authentication with the set-top box to verify whether the prisoner currently watching is an adult. Then, the headend transmits the adult broadcast data to the set-top box when the input password matches the previously registered password. As such, as the subscriber requests specific content, the service process for transmitting the content to the subscriber after authentication at the headend is the same in the IP-TV broadcasting system and the digital cable TV broadcasting system.

As mentioned above, in the IP-TV broadcasting service and the digital cable TV broadcasting service, the broadcasting channel restriction function is essentially implemented. As described above, the method of restricting the broadcasting channel as a result of authenticating the password inputted by the subscriber is problematic. have.

In other words, parents register passwords in set-top boxes or headends to prevent young children from watching pay or adult broadcasts. These passwords are easily exposed to young children, and children can easily enter harmful passwords by entering passwords. There is a problem that you can watch.

As another example, a broadcast reception limiting device (CI; Conditional Access Module) for limiting paying or paying adult broadcasting is provided in a set top box in the form of a smart card. However, even if the parent removes the broadcast reception restriction device from the set top box when going out, there is a problem that a young child can easily watch harmful broadcasts simply by inserting the broadcast reception restriction device into the set top box.

On the other hand, recently, home network technology capable of automating the control of various electrical / electronic devices installed in the home has been in the spotlight. The home network includes a residential gateway (RG) for controlling various devices (e.g., a security device, a gas leak detector, a fire detector, a remote meter, a telephone, a refrigerator, a microwave oven, a TV, etc.) installed in each home, The home gateway consists of a Home Management Server (HOMS) that remotely controls / manages the Internet.

For example, the home gateway registers information of various devices installed in each home as a home management server, and the home management server controls the operation of the corresponding electric / electronic device according to the registration information of the home gateway. Here, the subscriber accesses a customer center, a wired internet site, a wireless internet site, and the like through various communication devices such as a telephone, a computer, a mobile communication terminal, and registers device control information with a home management server (eg, microwave operation from hours to hours). Etc.). Accordingly, the home management server instructs the home gateway to operate the microwave oven at the corresponding time with reference to the subscriber control information, and accordingly, the home gateway operates the microwave by the command of the home management server.

As another example, when a home gateway monitors various devices and detects an abnormality of a specific device (e.g., malfunction of a refrigerator), or detects occurrence of a specific event (e.g., detects an illegal intruder, etc.) Report to the management server. Then, the home management server takes appropriate measures (eg, to notify the police station near the subscriber's home), and informs the subscriber's mobile terminal of the matter so that the subscriber can recognize the matter.

As mentioned above, the home gateway is equipped with a TV broadcast reception (aka set-top box) function (a data transmission request function corresponding to a broadcast channel and a data reception function corresponding to a broadcast channel). Converts and transmits broadcast data into a signal suitable for TV (or data relaying immediately, that is, signal processing in TV without additional signal processing), or converts and transmits digital cable TV broadcast data into a signal suitable for TV (or separate signal processing) Only the function of data relaying, i.e. signal processing on a TV, without a process is installed.

Therefore, by incorporating home network technology into IP-TV broadcasting service or digital cable TV broadcasting service, children should not be sure to watch harmful broadcasts according to the broadcasting channel information specified by their parents, and they should try to watch harmful broadcasting. There is an urgent need for technology that informs parents of the facts and allows parents to remotely watch specific broadcasts of children according to the needs of young children.

The present invention is to solve the problems of the prior art as described above and to meet the above requirements, and remotely between the home gateway (RG) and the home gateway in each home equipped with a TV broadcast reception (aka set-top box) function In a home network made up of managed home management servers (HOMSs), broadcast channel information designated by subscribers is registered in the home management server, and broadcast data transmitted and received from the home gateway through data sync with the home management server. It is an object of the present invention to provide a system and a method for filtering TV broadcast channels in a home network.

A system of the present invention for achieving the above object is a TV in a home network including a home gateway (RG) in each home equipped with a TV broadcast reception function and a home management server (HOMS) for remotely managing the home gateway. In the broadcast channel restriction system, the home management server registers broadcast channel information designated by a subscriber, and transmits the registered broadcast channel information to the home gateway through a data sync, and the home gateway is configured to: When the broadcast channel information designated by the subscriber is stored through a data sink with a home management server, when a specific broadcast channel request signal is received from a TV, the specific broadcast channel request signal is filtered as a result of inquiring the broadcast channel information. When specific broadcast data is received from a head-end, the broadcast channel information is searched. It characterized in that it filters the information broadcast data.

Meanwhile, the method of the present invention is a method for restricting a TV broadcast channel in a home network including a home gateway (RG) in each home equipped with a TV broadcast reception function and a home management server (HOMS) for remotely managing the home gateway. Registering, by the home management server, broadcast channel information designated by the subscriber, and transmitting the registered broadcast channel information to the home gateway through a data sync; A second step of storing, by the home gateway, broadcast channel information received through a data sink with the home management server; And when the home gateway receives a specific broadcast channel request signal from a TV, filters the specific broadcast channel request signal as a result of inquiring the broadcast channel information, and receives the specific broadcast data from a head-end. And filtering the specific broadcast data as a result of inquiring channel information.

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

1 is a configuration diagram of an embodiment of a communication network to which the present invention is applied.

As shown in FIG. 1, the IP-TV broadcasting service providing communication network includes a broadcasting station 10 that transmits airwave / wired TV broadcasting, and an audio / video source in analog form (eg, movie, music, etc.). A / V provider 11 to provide a, a content provider 12 to provide a variety of digital content (eg interactive quiz show, TV banking, home shopping, stock trading, etc.), the broadcasting station (10), A Encoder 20 for converting analog data received from / V provider 11 and content provider 12 into digital data suitable for data transmission, the broadcasting station 10, A / V provider ( 11) and a headend 30 that transmits various data provided from the content provider 12 (e.g., broadcast data, TV program guide (EPG), movie, audio, home shopping, etc.) to each home, and each home. Set-top box 40a installed in the home gateway (in the present invention, the set-top box Also the function, and a not shown) and the TV (50).

In addition, the headend 30 is a multicasting (IP-multicasting) method for transmitting broadcast data to the set-top box 40a of each home, the IP-TV server 31, the various movies and audio based on the order of the subscriber VOD (Video On Demand) server 32 to provide, perform the subscriber authentication and the application to provide a variety of interactive content, services (eg interactive quiz show, TV banking, home shopping, stock trading, etc.) to the subscriber (Application ) Server 33 and subscriber DB 35 for storing subscriber information, set-top box information, and the like.

Meanwhile, although the IP-TV broadcasting service providing communication network has been described as an example, the present invention is also applied to the digital cable TV broadcasting service providing communication network and other TV broadcasting providing communication networks. It will be readily understood by those skilled in the art that the TV server 31 is replaced by a digital cable TV server, and the cable network of the above broadband communication network is used. Hereinafter, the IP-TV broadcasting service will be described as an example.

2 is a configuration diagram of an embodiment of a system for limiting TV broadcast channels in a home network according to the present invention.

As shown in Fig. 2, the TV broadcast channel restriction system in the home network according to the present invention provides a TV broadcast service to a subscriber [example; Headend 30 for transmitting the corresponding broadcast data according to the subscriber's specific broadcast channel selection to the home gateway 40, and the broadcast channel information designated by the subscriber (for example, the list of allowed broadcast channels or the restricted broadcast channels list, etc.) Home management server 60 for managing the information, subscriber DB (61), the home management server 60, which stores subscriber information (whether or not a home networking service subscription, home gateway information, mobile phone number, broadcast channel information, etc.) Filters broadcast data transmitted and received between the TV 50 and the head end 30 with the broadcast channel information while storing the broadcast channel information designated by the subscriber in the data storage unit 41 through data sync with A home gateway 40 passing through or discarding, and a TV 50 connected to the home gateway 40.

On the other hand, in the present invention, the home management server 60 of the SMS / 80, the home management server 60 for transmitting a message to the corresponding mobile communication terminal according to the short / long / multimedia / callback URL message transmission request According to the voice message transmission request, it is preferable to further include a customer center 90 for transmitting a voice message to the corresponding mobile communication terminal in the ARS method. In addition, the subscriber side is preferably provided with a mobile communication terminal (70).

In the present invention, for example, according to the broadcast channel information specified by the parent (broadcast channel access authority) so that the young child (broadcast channel access user) is not sure to watch harmful broadcasts (paid or adult broadcast, etc.), When a child tries to watch a harmful broadcast, the parent is notified of the fact and, at the request of the young child, the parent can remotely watch the specific broadcast of the young child.

To do this, the parent calls the home networking service customer center by using a landline phone or a mobile communication terminal to register broadcasting channel information (for example, a list of allowed broadcasting channels or a restricted broadcasting channel list) or a computer or mobile terminal. Access to the wired / wireless internet site operated by the home management server 60 to register broadcast channel information or input broadcast channel information through a key button provided in the home gateway 40 to the home management server 60. Register. Here, the parent may register the broadcast channel information to the home management server 60 with various communication devices. In particular, it is preferable that the parent be authenticated as the broadcast channel access authority by the home management server 60 at the time of registering the broadcast channel information.

On the other hand, the broadcast channel information registered by the parent is stored in the subscriber DB 61 of the home management server 60, the information is shared in real time through the data sink between the home management server 60 and the home gateway 40. That is, when the parent registers the broadcasting channel information to the wireless Internet site through the mobile communication terminal, the home management server 60 updates the broadcasting channel information to the subscriber DB 61 and remotely connects with the home gateway 40. By performing communication, the updated broadcast channel information is reflected in the data storage unit 41 of the home gateway 40.

In general, the home gateway 40 is assigned an IP address from an Internet service provider associated with the home management server 60 to be assigned a static IP address or a dynamic IP address, and has its own Plug & Play function. The home management server 60 performs home automation device addition / update / registration / deletion. In particular, the home management server 60 in the present invention through the home gateway 40 and the data sink in real time at the time of registering (add / delete / change) the broadcast channel information related to the TV 50 as well as the home automation device registration information Share registered broadcast channel information from subscribers.

As described above, when the parent goes out with the parental control broadcasting channel list or the parental control broadcasting channel list registered in the home management server 60 (and the home gateway 40 through the data sink), the child is allowed to watch TV (50) in the home. ) Watching as an example.

When the child selects an adult broadcasting channel (or a pay broadcasting channel) by operating a TV remote control or a TV button, the TV 50 requests the home gateway 40 to transmit a corresponding channel request signal to the headend 30. .

Then, the home gateway 40 inquires the data storage unit 41 and checks whether the channel requested from the TV 50 belongs to the viewing permission broadcast channel list (or the viewing restriction broadcast channel list). The home gateway 40 requests the broadcast channel requested from the TV 50 if the broadcast channel requested from the TV 50 does not belong to the viewing allowed broadcast channel list (or the viewing restriction broadcast channel list) as a result of the inspection. The signal is discarded and not transmitted to the headend 30, and the TV 50 is notified that the broadcast channel is not viewable so that the child cannot watch the broadcast channel. On the other hand, if the broadcast channel requested from the TV 50 as a result of the inspection belongs to the list of viewing allowed broadcast channel, the home gateway 40 passes the broadcast channel request signal requested from the TV 50 headend 30 The broadcast data corresponding to the corresponding channel received from the headend 30 is transmitted to the TV 50 as a result of the broadcast channel request signal transmission. In this case, the home gateway 40 performs a process of checking whether the home gateway 40 belongs to the viewable broadcast channel list even when the broadcast data is received from the headend 30, which will be described later in relation to the corresponding contents. .

When the home gateway 40 receives a non-viewable broadcast channel request from the TV 50, the home gateway 40 reports the fact (the non-viewable broadcast channel selection fact) to the home management server 60. Accordingly, the home management server 60 looks up the subscriber DB 61 to find the phone number of the parent's mobile terminal 70, and then the parent's mobile terminal through the SMS center 80 or the customer center 90. In step 70, a short / long / multimedia / callback URL message or a voice message is notified of the fact that the user cannot view the broadcast channel at home. Thus, even when the parent is located outside the home, it is possible to recognize which broadcast channel the child is watching, and if the child tries to watch the harmful broadcast channel, the child can be called to take care of the child.

In addition, the home gateway 40 determines whether the channel requested from the TV 50 belongs to the viewing permission broadcast channel list by inquiring the data storage unit 41, and the data storage unit is connected to the home gateway 40. It is also possible to forward the broadcast channel request signal received from the TV 50 to the home management server 60 without querying 41 to query whether it belongs to the list of allowed broadcast channels, and to limit the broadcast channel viewing based on the response. .

However, in general, a delay occurs during switching of a broadcast channel due to the time required for communication between the headend 30 and the home gateway 40 in a TV broadcast service, so that the subscriber is shown after about 1 to 2 seconds. For example, it is desirable to show the broadcast to the subscriber as soon as possible by eliminating the question / answer process between the home gateway 40 and the home management server 60. Similarly, when the home data is received from the headend 30 at the home gateway 40, the same is true.

On the other hand, when the parents go out to book the adult broadcast channel to the headend 30 through the TV 50 to watch the adult broadcast channel at a specific time, for example, the child is located around the home TV 50 For example, it is as follows. As another example, the case where the wrong broadcast data (ie, adult broadcast data not required in the home or adult broadcast data to be transmitted to other homes) is transmitted to the home in the headend 30.

Even if the parent does not return to the home at the scheduled time for watching the adult broadcast channel, when the time is reached, the home TV 50 is automatically driven, and the headend 30 transmits broadcast data corresponding to the reserved adult broadcast channel to the home gateway. And transmits the broadcast data to the home gateway 40.

Then, the home gateway 40 inquires the data storage unit 41 and checks whether the channel of the broadcast data received from the headend 30 belongs to the viewing permission broadcast channel list (or the viewing restriction broadcast channel list). If the channel of the broadcast data received from the headend 30 does not belong to the viewable broadcast channel list (or the view limit broadcast channel list) as a result of the check, the home gateway 40 receives the data from the headend 30. The received broadcast data is discarded and not transmitted to the TV 50, and the TV 50 is notified that the broadcast channel is not viewable so that the child cannot watch the broadcast channel. On the other hand, if the channel of the broadcast data received from the headend 30 as a result of the inspection belongs to the list of viewing allowed broadcast channel, the home gateway 40 passes the broadcast data to the TV 50.

When the home gateway 40 receives broadcast data corresponding to the non-viewable broadcast channel from the headend 30, the home gateway 40 reports the fact to the home management server 60. Accordingly, the home management server 60 looks up the subscriber DB 61 to find the phone number of the parent's mobile terminal 70, and then the parent's mobile terminal through the SMS center 80 or the customer center 90. In step 70, the user is notified of the fact that the user cannot view the broadcast data in the home via a short message, a long text, a multimedia, a callback URL message or a voice message. Accordingly, it is possible to recognize what broadcast data is received even when the parent is located outside the home, and when the harmful broadcast data is about to be seen, the user can call the home and take action on the child.

On the other hand, when the child selects the paid broadcast channel or fails to watch the broadcast channel as a result of receiving the paid broadcast data, if the parent contacts the parent and receives the consent to view the paid broadcast channel, or the parent pays the paid broadcast channel. For example, approving the viewing of the pay broadcasting channel by recognizing the fact of selection is as follows.

As the child selects the pay broadcasting channel or receives the pay broadcasting data, the parent recognizes the fact through his mobile terminal 70 or the child calls the parent's mobile terminal 70 and the pay broadcasting channel. Ask to watch.

Then, the parent accesses the home management server 60 connected to the home networking service customer center, the wired / wireless internet site, etc. through a mobile communication terminal 70 or a wired telephone or a computer, and authenticates a predetermined broadcast channel access authority. After passing through, the corresponding broadcast channel allowance is checked in the broadcast channel information (broadcast channel information update).

Accordingly, the broadcast channel information registered in the subscriber DB 61 of the home management server 60 is updated, and the broadcast channel information registered in the data storage unit 41 of the home gateway 40 through the data sink is also updated. .

Thereafter, the home gateway 40 inquires the updated broadcast channel information and passes the paid broadcast channel request signal and the paid broadcast data. Thus, the child can watch the pay-TV channel through the TV (50).

In addition, the broadcast channel request signal between the headend 30, the home gateway 40 and the TV 50 is transmitted and received in a message based on the CCP protocol, and the home gateway 40 is carried in the message. From the broadcast channel information, it is determined which broadcast channel selection has been made from the TV 50.

In addition, H.264 data (MPEG-4 Part 10 or MPEG-4 AVC (Advanced Video Codec)) in the form of a stream is used as broadcast data between the headend 30, the home gateway 40, and the TV 50. The home gateway 40 determines which broadcast channel corresponding to the broadcast channel is received from the headend 30 through the broadcast channel information inserted in the header of the H.264 data.

Meanwhile, although the standard of the broadcast channel request signal and the broadcast data standard may vary according to a communication protocol provided with a TV broadcast service, those skilled in the art can easily understand that the broadcast channel request signal and the broadcast data include corresponding broadcast channel information. It will be apparent to those skilled in the art that the home gateway 40 detects broadcast channel information based on a corresponding standard and filters or passes through the broadcast channel request signal and broadcast data in the present invention.

3A and 3B are flowcharts illustrating an embodiment of a method for restricting a TV broadcast channel in a home network according to the present invention.

First, a parent accesses the home management server 60 through his mobile communication terminal 70 and registers broadcast channel information (eg, a viewable broadcast channel list, etc.) through a predetermined broadcast channel access authority authentication procedure. (300).

Then, the home management server 60 stores the broadcast channel information in the subscriber DB 61 (301a), and the data storage unit of the home gateway 40 through the data sink with the home gateway 40 of the subscriber Broadcast channel information is stored at 41 (301b).

Subsequently, when the child selects a specific broadcast channel by operating the TV remote control or the TV button, the child requests to transmit the specific broadcast channel request signal to the headend 30 from the TV 50 to the home gateway 40. (302).

Then, the home gateway 40 checks the broadcast channel information stored in the data storage unit 41 and checks whether the broadcast channel requested from the TV 50 belongs to the viewing permission broadcast channel list (303).

The home gateway 40 transmits the broadcast channel request signal to the headend 30 when the broadcast channel requested from the TV 50 belongs to the viewing permission broadcast channel list (303a). On the other hand, if the test result 303, the broadcast channel requested from the TV 50 does not belong to the viewing allowed broadcast channel list, the home gateway 40 discards the broadcast channel request signal (304b), the TV 50 Notify that the broadcast channel is unavailable.

In addition, when the test result 303 and the broadcast channel requested from the TV 50 do not belong to the list of viewable broadcast channels, the home gateway 40 reports to the home management server 50 the selection of the non-viewable broadcast channel. (305).

Then, the home management server 50 inquires the mobile phone terminal number of the subscriber (parent) (306), and transmits to the mobile communication terminal 70 the fact that the broadcast channel selection is not available to the SMS center (80). It is requested to do (307).

Accordingly, the SMS center 80 notifies the mobile communication terminal 70 of the fact that the non-viewable broadcast channel is selected by a short / long text / multimedia / callback URL message or the like (308). Thus, even when the parent is located outside the home, it is possible to recognize which broadcast channel the child is watching, and if the child tries to watch the harmful broadcast channel, the child can be called to take care of the child.

On the other hand, when the reservation is made to watch a specific broadcast channel in the headend 30 by the parent (350), when the reservation time is reached, the headend 30 sends broadcast data corresponding to the broadcast channel to the home gateway 40. Send (351). Accordingly, the home gateway 40 receives broadcast data.

Then, the home gateway 40 checks the broadcast channel information stored in the data storage unit 41 and checks whether the broadcast channel of the broadcast data received from the headend 30 belongs to the viewable broadcast channel list ( 352).

When the test result 352 and the broadcast channel of the broadcast data received from the headend 30 belongs to the list of viewing allowed broadcast channels, the home gateway 40 transmits the broadcast data to the TV 50 (353a). . On the other hand, if the test result 352, the broadcast channel of the broadcast data received from the head end 30 does not belong to the viewing allowed broadcast channel list, the home gateway 40 discards the broadcast data (353b), TV ( 50) to notify that the broadcast data that cannot be viewed is received.

In addition, when the test result 352 and the broadcast channel of the broadcast data received from the headend 30 do not belong to the viewing allowable broadcast channel list, the home gateway 40 informs the home management server 50 of the fact that the broadcast data is not received. (354).

Then, the home management server 50 inquires the mobile phone terminal number of the subscriber (parent) (355), and transmits the fact that the broadcast data reception is not received to the SMS center 80 to the mobile terminal 70. It is requested to do (356).

Accordingly, the SMS center 80 notifies the mobile communication terminal 70 of the fact that the unviewable broadcast data has been received in a short / long text / multimedia / callback URL message or the like (357). Accordingly, it is possible to recognize what broadcast data is received even when the parent is located outside the home, and when the harmful broadcast data is about to be seen, the user can call the home and take action on the child.

On the other hand, when a parent can watch a specific broadcast channel is as follows.

First, a parent accesses the home management server 60 through his mobile communication terminal 70 and changes broadcast channel information (eg, a viewable broadcast channel list) through a predetermined broadcast channel access authority authentication procedure. (390).

Then, the home management server 60 updates the broadcast channel information previously stored in the subscriber DB 61 (391a), and the home gateway 40 of the home gateway 40 through a data sink with the home gateway 40 of the subscriber. The broadcast channel information previously stored in the data storage unit 41 is updated (391b).

Subsequently, when the child selects the pay broadcasting channel by operating the TV remote control or the TV button, the child requests to transmit the pay broadcasting channel request signal to the headend 30 from the TV 50 to the home gateway 40. (392).

Then, the home gateway 40 inquires the broadcast channel information stored in the data storage unit 41 and confirms that the paid broadcast channel requested from the TV 50 belongs to the viewing permission broadcast channel list (393). The pay channel request signal is transmitted to the headend 30 (394). Accordingly, the headend 30 transmits pay broadcast data corresponding to the pay broadcast channel to the home gateway 40 (395).

Then, the home gateway 40 inquires about the broadcast channel information stored in the data storage unit 41 and confirms that the broadcast channel of the paid broadcast data received from the headend 30 belongs to the viewing allowable broadcast channel list. The pay broadcast data is transmitted to the TV 50 (396) (397). Accordingly, the TV 50 outputs pay broadcast data (398). Thus, the child in the home can watch the pay TV through the TV (50).
