It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

In order to achieve the above object, an apparatus for providing an on-premises broadcasting service in a hybrid network having a plurality of heterogeneous broadcast communication networks according to the present invention comprises: a plurality of broadcast communication modules each communicating with a plurality of heterogeneous broadcast communication networks distributed in the hybrid network; And transmitting the broadcast content to a plurality of broadcast terminals designated by using one or more of the plurality of broadcast communication modules, and measuring the load rate of each broadcast communication network distributed in the hybrid network, so that the load rate of the first broadcast communication network exceeds a threshold value. Select one or more broadcasting terminals to be switched among all broadcasting terminals connected to the first broadcasting network, and convert the access paths of the selected one or more broadcasting terminals from the first broadcasting communication network to the second broadcasting communication network; And a service controller for subsequently transmitting the broadcast content to a broadcast terminal switched to the access path using a broadcast communication module communicating with the second broadcast communication network.

Since the present invention provides an on-premises broadcasting service by selecting one or more of a plurality of heterogeneous broadcasting communication networks distributed in a hybrid network, an advantage of providing an uninterrupted broadcasting service to a user using another broadcasting communication network even when a failure occurs in a specific broadcasting communication network. There is this.

In addition, the present invention proposes a broadcast terminal that is compatible with all of a plurality of heterogeneous broadcast communication networks, so that even if the internal network is changed, the broadcast service is continuously used by using the previously established broadcast terminal without separately purchasing the broadcast terminal for the internal network. There is an advantage to providing users.

In particular, the service control unit 140 checks whether a reservation time is specified in the broadcast content, and if so, extracts the content from the storage unit 130 at the reservation time and transmits the content to the designated broadcast terminal 500-N. . In addition, when the service control unit 140 receives a request for upstream broadcast from the broadcast terminal 100 -N, the broadcast communication network for the uplink broadcast based on the load rate and the requested broadcast type of each broadcast communication network 200, 300, 400, 600. (200, 300, 400, 600) are selected, and the broadcast terminal (100-N) is connected to the selected broadcast communication network (200, 300, 400, 600).

In addition, when the path switching module 141 is instructed to stop broadcasting for a specific broadcast communication network 200, 300, 400, 600 by an administrator, the broadcast terminal 100 connected to the corresponding broadcast communication network 200, 300, 400, 600. -N) switch the connection path.

Hereinafter, the operation of the premises broadcasting service device 100 according to the present invention will be described in more detail with reference to FIGS. 4 to 8.

4 is a flowchart illustrating a method for performing load balancing of heterogeneous broadcasting communication networks in a premises broadcasting service device according to an embodiment of the present invention.

In the description with reference to FIG. 4, it is assumed that the load is increased in the UTP-IP network 200.

Referring to FIG. 4, when the input unit 110 of the premises broadcasting service device 100 receives a broadcast content and a broadcast group from an administrator, the service control unit 140 includes a plurality of broadcast terminals 500 -N belonging to the broadcast group. In step S401, the broadcast content is transmitted. At this time, the service control unit 140 is one or more of the UTP-IP broadcast communication module 121, HFC-IP broadcast communication module 122, HFC-CATV broadcast communication module 123, HFC-ATSC broadcast communication module 124 The broadcast content is transmitted to the broadcast terminal 500-N by using a. In detail, the service controller 140 determines which broadcast communication network 200, 300, 400, or 600 is connected to each broadcast terminal 500 -N belonging to the group based on the network table of the storage 130. The broadcast content is transmitted to the broadcast terminal 500-N of the designated group by using the broadcast communication modules 121, 122, 123, and 124 communicating with the corresponding broadcast communication networks 200, 300, 400, and 600. .

Then, the service control unit 140 monitors the communication status of each heterogeneous broadcasting communication network 200, 300, 400, 600 by using the plurality of broadcasting communication modules 121, 122, 123, and 124. The load rate of the 200, 300, 400, 600 is measured and recorded in the network table of the storage unit 130 (S403). At this time, the service control unit 140 continuously measures the data throughput transmitted and received by each of the broadcast communication networks 200, 300, 400, and 600 by using the plurality of broadcast communication modules 121, 122, 123, and 124, By dividing the data throughput currently transmitted / received by the broadcasting network 200, 300, 400, 600 by the data throughput that the specific broadcasting network 200, 300, 400, 600 can collectively transmit / receive, 200, 300, 400, 600 load ratio can be calculated. Alternatively, the service control unit 140 checks the amount of bandwidth being used by each broadcasting communication network 200, 300, 400, 600, and records it in the network table of the storage unit 130, and records the specific broadcasting communication network 200, 300, 400. , By dividing the bandwidth amount of the corresponding broadcast communication networks 200, 300, 400, and 600 by the maximum bandwidth of 600, the load ratio of the broadcast communication networks 200, 300, 400, and 600 may be calculated. In another method, the service control unit 140 combines the data throughput, bandwidth, maximum data throughput, and maximum bandwidth of the corresponding broadcast communication network 100, 200, 300, and the corresponding broadcast communication network 200, 300, 400, 600. The load factor of can be calculated.

Next, the route switching module 141 is based on the load ratio of each broadcasting network 200, 300, 400, 600 recorded in the network table, the threshold for each broadcasting network 200, 300, 400, 600 predetermined threshold It is checked whether the value (eg, 80%) is exceeded (S405). Subsequently, when the load ratio of the specific broadcast communication networks 200, 300, 400, and 600 exceeds the threshold, the path switching module 141 connects the plurality of broadcasts connected to the broadcast communication networks 200, 300, 400, and 600. The terminal 500 -N checks the network table, and selects a plurality of broadcast terminals 500 -N to be switched among the plurality of broadcast terminals 500 -N (S407). At this time, the route switching module 141 may determine the number of broadcast terminals 500 -N to be routed based on the exceeded load rate, and may select as many broadcast terminals 500 -N as the determined number. For example, the path switching module 141 receives 100 broadcast terminals 500-N connected to a specific broadcast communication network 200, 300, 400, or 600, and receives the broadcast content. , 600) load rate is 90% (that is, when the load rate exceeds the threshold value of about 10%), 12 broadcasts among 100 broadcasting terminals (500-N) to drop the load rate to a level below the threshold value The terminal 500 -N may be selected as the broadcast terminal 500 -N to be switched.

Next, the path switching module 141 selects the broadcast communication networks 200, 300, 400, and 600 to route the low load network based on the load ratio of each broadcast communication network recorded in the network table (S409). Preferably, the path switching module 141 may be configured to switch the broadcast communication networks 200, 300, 400, and 600 with the lowest load rates based on the load rates for the broadcasting communication networks recorded in the network table. 600).

Next, the path switching module 141 transmits the path switching request message including the identification information of the selected broadcasting communication network to the broadcasting terminal 500-N selected in step S407 (S411). At this time, the path switching module 141 uses the UTP-IP broadcasting communication module 121 to communicate with the UTP-IP network 200 to which the broadcast terminal 500-N to be switched is connected. Send a message. In FIG. 4, identification information of the HFC-IP network 300 is included as the broadcasting communication network identification information.

Each broadcast terminal 500-N receiving the path switch request message activates the HFC-IP broadcast communication module based on the broadcast communication network identification information included in the path switch request message (S413). Next, the broadcast terminal 500-N transmits a route switching notification message including its own terminal identification information to the premises broadcasting service device 100 via the HFC-IP network 300 (S415).

Then, the service control unit 140 of the on-premises broadcasting service device 100 confirms the identification information of the broadcast terminal 500-N and based on the terminal identification information, the broadcast via the UTP-IP network 200. The broadcast content being transmitted to the terminal 500-N is subsequently transmitted to the broadcast terminal 500-N via the HFC-IP network 300 (S417).

Next, if the broadcast content is normally received through the HFC-IP broadcast communication module, the broadcast terminal 500-N deactivates the UTP-IP broadcast communication module (S419). That is, even if the broadcast terminal 500-N receives the route switching request message from the premises broadcasting service device 100 in step S411 in order to receive the broadcast content without interruption from the premises broadcasting service device 100, the HFC-IP broadcasting is performed. The UTP-IP broadcast communication module is activated until the broadcast content is received through the communication module. Accordingly, even if the access terminal 500-N switches the access path according to load balancing, the broadcast terminal 500 -N continuously receives the broadcast content from the premises broadcasting service device 100 continuously.

As such, when the broadcast content is received through another broadcast communication network (ie, HFC-IP network), the broadcast terminal 500 -N indicates that the path switching from the UTP-IP network 200 to the HFC-IP network 300 is completed. The indicated message is transmitted to the premises broadcasting service device 100 via the HFC-IP network 300 (S421).

Then, the service control unit 140 of the premises broadcasting service device 100 stores the identification information of the broadcasting terminal 500-N recorded in correspondence with the identification information of the UTP-IP network 200 of the storage unit 130. The identification information of the broadcast terminal 500-N is recorded in the terminal identification information field 38 corresponding to the identification information of the HFC-IP network 200 and deleted from the table (S423). That is, the service controller 140 updates the network table by recording in the network table that the broadcast terminal 500 -N having switched the access path has connected to the HFC-IP network 300.

FIG. 5 is a flowchart illustrating a method of switching a connection path of a broadcast terminal to another broadcast communication network according to a request of an administrator in an on-premises broadcasting service device according to an embodiment of the present invention.

Referring to FIG. 5, when the input unit 110 of the on-premises broadcasting service device 100 receives a broadcast content and a broadcast group from an administrator, the service control unit 140 includes a plurality of broadcast terminals 500 -N belonging to the broadcast group. In step S501, the broadcast content is transmitted. At this time, the service controller 140 checks which broadcast communication network 200, 300, 400, or 600 is connected to the broadcast terminal 500-N belonging to the group based on the network table of the storage 130. The broadcast content is transmitted to the broadcast terminal 500-N by using the broadcast communication modules 121, 122, 123, and 124 communicating with the corresponding broadcast communication networks 200, 300, 400, and 600.

Subsequently, the input unit 110 receives an interruption of the broadcast service for the specific broadcast communication network 200 from the plurality of broadcast communication networks 200, 300, 400, and 600 from the manager (S503). That is, the input unit 110 is a line change, maintenance, etc. in the specific broadcast communication network 200 is in progress, the communication breakdown in the corresponding broadcast communication network 200 is expected, from the manager to the corresponding broadcast communication network 20 Receives a broadcast service interruption. In FIG. 5, it is assumed that the input unit 110 receives an interruption of a broadcast service for the UTP-IP network 200.

Then, the path switching module 141 checks the plurality of broadcasting terminals 500-N connected to the UTP-IP network 200 in the network table of the storage unit 130, and the UTP-IP broadcasting communication module 121 ) Transmits the UTP-IP network interruption message to the premises broadcasting service device 100 to the plurality of broadcast terminals 500-N identified above (S505).

Next, as the broadcast terminal 500-N receives the UTP-IP network broadcast interruption message, the broadcast terminal 500-N activates one of the other communication modules except for the UTP-IP communication module and identifies itself using the activated communication module. The route switching notification message including the information is transmitted to the premises broadcasting service device 100 (S507 and S509). In FIG. 5, the broadcast terminal 500-N connected to the UTP-IP network 200 activates the HFC-IP broadcast communication module and routes to the premises broadcasting service device 100 via the HFC-IP network 300. It is described to send a switch notification message.

Subsequently, the service control unit 140 checks the identification information of the broadcasting terminal 500-N and transmits the identification information of the broadcasting terminal 500-N to the broadcasting terminal 500-N via the UTP-IP network 200 based on the terminal identification information. The broadcast content is subsequently transmitted to the broadcast terminal 500-N via the HFC-IP network 300 (S511).

When the broadcast content is normally received through the HFC-IP broadcast communication module, the broadcast terminal 500 -N deactivates the UTP-IP broadcast communication module (S513). That is, even if the broadcast terminal 500-N receives the broadcast stop message in step S505 in order to receive the broadcast content without interruption from the premises broadcasting service device 100, the broadcast content is broadcast through the HFC-IP broadcasting communication module. The UTP-IP broadcast communication module is activated until received from the service device 100. Subsequently, the broadcast terminal 500 -N receives a message indicating that the path switching is completed from the UTP-IP network 200 to the HFC-IP network 300 via the HFC-IP network 300. In step (S515).

Then, the service control unit 140 deletes the identification information of the broadcast terminal 500-N recorded in correspondence with the identification information of the UTP-IP network 200 from the network table of the storage unit 130, and removes the HFC-IP. The identification information of the broadcast terminal 500-N is recorded in the terminal identification information field 38 corresponding to the identification information of the network 300 (S517). That is, the service control unit 140 updates the network table by recording in the network table that the broadcast terminal 500 -N has connected to the HFC-IP network 300. Subsequently, the service control unit 140 checks whether all broadcasting terminals 500 -N connected from the UTP-IP network 200 have completed the path switching to other broadcasting communication networks 300 and 400 based on the network table. When it is completed, the path switching completion message is output to the monitor or the speaker so that the work in the UTP-IP network 200 is performed by the administrator.

Next, when the maintenance work in the UTP-IP network 200 is completed by the administrator, the input unit 110 of the premises broadcasting service device 100 inputs the recovery information of the UTP-IP network 200 from the administrator. Received (S519). Then, the service controller 140 uses the HFC-IP broadcast communication module 122, the HFC-CATV broadcast communication module 123 and the HFC-ATSC communication module 124 except for the UTP-IP broadcast communication module 121. A message informing that the restoration of the UTP-IP network 200 is completed is broadcasted (S521). That is, the service control unit 140 restores the UTP-IP network 200 to the HFC-IP network 300, the HFC-CATV network 400, and the HFC-ATSC network 600 except for the UTP-IP network 200. Broadcasts a message indicating that

Then, the broadcast terminal 500-N receives the recovery message of the UTP-IP network 200, and accordingly, when another broadcast communication network 300, 400, 600 fails or the broadcast communication quality is poor, the UTP It is possible to change the connection path to the IP network (200).

On the other hand, the premises broadcasting service device 100 outputs broadcasting terminal information connected to the broadcasting communication networks 200, 300, 400, and 600 on the screen, and among these, the administrator switches the connection switching command of the specific broadcasting terminal 500-N. It is also possible to change the connection path of this broadcasting terminal 500-N to another broadcasting communication network 200, 300, 400, 600. For example, when the input unit 110 receives an operation signal from the manager to change the connection path of the first broadcast terminal 500-1 connected to the UTP-IP network 200 to the HFC-CATV network 400, The path switching module 141 may change the connection path of the first broadcasting terminal 500-1 from the UTP-IP network 200 to the HFC-CATV network 400 based on the manipulation signal.

Through the method of FIG. 5, the manager may transfer the broadcasting terminal 500 -N that is connected to the specific broadcasting network 200, 300, 400, 600 that requires maintenance work to another broadcasting network 200, 300, 400, 600. By switching the access, it is possible to proceed with the maintenance work for the broadcast network (200, 300, 400, 600) without interrupting the broadcast service.

6 is a flowchart illustrating a method of switching a connection path of a broadcast terminal according to broadcast communication quality in a premises broadcasting service device according to an embodiment of the present invention.

Referring to FIG. 6, when the input unit 110 receives broadcast content and broadcast group information from an administrator, the service controller 140 belongs to a broadcast group using a plurality of broadcast communication modules 121, 122, 123, and 124. The broadcast content is transmitted to a plurality of broadcast terminals 500 -N (S601).

Then, the broadcast terminal 500-N measures the quality of broadcast communication with the internal broadcast service device 100 (S603). That is, the broadcast terminal 500-N measures a packet loss rate, an audio packet delay time, a video packet delay time, and the like based on the packet received from the premises broadcasting service device 100. Subsequently, the broadcast terminal 500 -N transmits the measured broadcast communication quality information to the premises broadcasting service device 100 at regular intervals (S605).

Then, the service control unit 140 of the on-premises broadcasting service device 100 records the broadcast communication quality information (voice delay time, video delay time, packet loss rate) received from the broadcast terminal 500-N, and then records in a network table. The broadcast communication quality information is analyzed to determine whether the broadcast communication quality of the broadcast terminal 500-N is good or poor (S607). For example, if the packet loss rate exceeds 1% or any one of the video delay time and audio delay time exceeds 150ms, the service control unit 140 has a poor broadcast communication quality of the broadcast terminal 500-N. It may be determined that broadcast content is not normally provided.

Next, if it is determined that the broadcast communication quality of the broadcast terminal 500-N is poor, the service control unit 140 instructs the path switching module 141 to switch the path of the corresponding broadcast terminal 500-N. Then, the path switching module 141 is HFC-IP network 300, HFC-CATV network 400, HFC except for the UTP-IP network 200 which is a broadcast communication network to which the broadcasting terminal 500-N is connected. Among the ATSC networks 600, the broadcast communication networks 300, 400, and 600 to be switched to the access path are selected with reference to the network table (S609, S611). At this time, the path switching module 141 may check the load rate for each broadcast communication network (300, 400, 600) in the network table, and may select the broadcast communication network that will route the least load among the broadcast communication network among the least. . Alternatively, the route switching module 141 checks the type of broadcast content provided by the broadcast terminal 500-N, and broadcasts a network communication path 300, 400, or 600 suitable for the type of the broadcast content. Can be selected. For example, the path switching module 141 may select the HFC-CATV network 400 as a broadcast communication network to switch the path when the broadcast terminal 500 -N is receiving audio content, or the broadcast terminal 500. If the N-N) is receiving video content, the HFC-IP network 300 may be selected as a broadcast communication network to which the channel is to be switched. In FIG. 6, it is described that the path switching module 141 selects the HFC-IP network 300 as the broadcast communication network to be switched.

After the path switching module 141 selects a broadcast communication network to switch the access path, the broadcast terminal 500-N receives the path change request message including the identification information of the broadcast communication network using the UTP-IP broadcast communication module 121. (S613). Then, the broadcast terminal 500-N activates the HFC-IP broadcast communication module based on the broadcast communication network identification information (ie, HFC-IP network identification information) included in the path switching request message (S615). Subsequently, the broadcast terminal 500-N transmits a route switching notification message including its identification information to the premises broadcasting service device 100 via the HFC-IP network 300 (S617). Then, the service control unit 140 checks the identification information of the broadcast terminal 500-N, and transmits it to the broadcast terminal 500-N through the UTP-IP broadcast communication module 121 based on the terminal identification information. The broadcast content being used is then transmitted to the broadcast terminal 500-N using the HFC-IP broadcast communication module 122 (S619). That is, the service control unit 140 transmits the broadcast content being transmitted to the broadcast terminal 500 -N via the UTP-IP network 200 via the HFC-IP network 300 through the broadcast terminal 500 -N. Then transmit.

Next, if the broadcast content is normally received through the HFC-IP broadcast communication module, the broadcast terminal 500-N deactivates the UTP-IP broadcast communication module (S621). That is, even if the broadcast terminal 500-N receives the route switching request message in step S613 in order to receive the uninterrupted broadcast content from the on-premises broadcasting service device 100, the broadcast content is premises through the HFC-IP broadcast communication module. The UTP-IP broadcast communication module is activated until received from the broadcast service device 100. Subsequently, the broadcast terminal 500 -N broadcasts a premises broadcast via the HFC-IP network 300 to notify the completion of the path switching from the UTP-IP network 200 to the HFC-IP network 300. The service device 100 transmits the data to the service device 100 in operation S623.

Then, the service control unit 140 updates the network table by recording in the network table that the broadcast terminal 500-N having switched the access path has connected to the HFC-IP network 300 (S625).

7 is a flowchart illustrating a method of performing an uplink broadcast service by designating an access path of a broadcast terminal requesting uplink broadcast in a premises broadcast service device according to an embodiment of the present invention.

Referring to FIG. 7, the broadcast terminal 500-N receives group contents from the premises broadcasting service apparatus 100 via the UTP-IP network 200 and outputs them to a monitor or a speaker. Receives a broadcast start signal including a (S701).

Then, the broadcast terminal 500 -N transmits a message requesting selection of an uplink broadcasting network to the premises broadcasting service device 100 via the currently connected UTP-IP network 200 (S703). Then, the UTP-IP broadcasting communication module 121 of the premises broadcasting service device 100 receives an uplink broadcasting network selection request message from the broadcasting terminal 500 -N, and the service control unit 140 transmits the broadcasting communication network 200. The load rate for each of 300, 400, and 600 is checked in the network table of the storage unit 130, and a broadcast communication network having the lowest load rate is selected as the uplink communication network of the broadcast terminal 500-N (S705 and S707). . At this time, the service control unit 140 excludes the UTP-IP network 200 which is a reception path of the uplink broadcasting network selection request message from the selection target broadcasting communication network.

Alternatively, the service control unit 140 checks the uplink type of the broadcast terminal 500 -N, and broadcasts suitable for the uplink type among the broadcast communication networks 300, 400, and 600 except for the UTP-IP network 200. The communication networks 300, 400, and 600 may be selected as uplink communication networks. For example, the service controller 140 may select the HFC-CATV network 400 as the uplink broadcast network of the broadcast terminal 500-N when the uplink broadcast type requested by the broadcast terminal 500-N is an audio broadcast. If the broadcaster 500-N requests the uplink broadcast type to be a video broadcast, the HFC-CATV network 400 may be selected as the uplink broadcast network of the broadcast terminal 500-N. In FIG. 7, the service control unit 140 selects the HFC-IP network 300 as the uplink broadcasting network.

In this way, the service control unit 140 selects an uplink broadcasting network, and then broadcasts an uplink broadcasting network response message including the identification information of the broadcasting network 300 using the UTP-IP broadcasting communication module 121 to the broadcasting terminal 500-N. (S709). Then, the broadcasting terminal 500-N activates the HFC-IP broadcasting communication module based on the HFC-IP network identification information included in the uplink broadcasting network response message, and uses the HFC-IP broadcasting communication module to broadcast the campus. The broadcast start request message is transmitted to the service device 100 in operation S711 and S713. At this time, the broadcast terminal 500-N includes the broadcast group identification information received from the user in the broadcast start request message.

Next, the service control unit 140 forms a session with the broadcasting terminal 500-N by using the HFC-IP broadcasting communication module 122, and broadcasts the contents of the broadcasting from the broadcasting terminal 500-N through the session. It is provided (S715, S717). That is, the premises broadcasting service device 100 forms a session with the broadcast terminal 500-N via the HFC-IP network 300, and receives broadcast content from the broadcast terminal 500-N through the session. .

Subsequently, the service control unit 140 checks the identification information of the plurality of broadcast terminals 500 -N corresponding to the group identification information included in the broadcast start request message in the group information table of the storage unit 130 and upwards it based on the identification information. The broadcast content is transmitted to a broadcast terminal 500-N designated as a broadcast destination (S719).

Through the method of FIG. 7, the premises broadcasting service apparatus 100 according to the present invention provides a broadcasting service by changing a downlink broadcasting channel which is a broadcast subject and an uplink broadcasting channel where the broadcasting terminal 500-N is a subject. do. That is, the broadcast terminal 500-N activates a first broadcast communication module required for downlink broadcasting to receive broadcast content from the premises broadcasting service device 100, and activates a second broadcast communication module necessary for uplink broadcasting to broadcast premises. By providing the broadcast content to the service device 100, the load of the heterogeneous broadcast communication networks 200, 300, 400, and 600 is distributed.

8 is a flowchart illustrating a method of switching a connection path to another broadcast communication network instead of a failed broadcast communication network in a broadcast terminal according to an embodiment of the present invention.

In the description with reference to FIG. 8, it is assumed that a failure occurs in the UTP-IP network 200.

Referring to FIG. 8, the broadcast terminal 500-N receives and outputs broadcast content from the premises broadcasting service device 100 through the activated UTP-IP broadcast communication module (S801). At this time, the broadcast terminal 500-N continuously checks whether a failure such as a communication disconnection occurs in the UTP-IP network 200, and if a failure occurs, the HFC-IP network broadcasting communication module or the HFC-CATV broadcasting communication module. Activate (S803, S805). In FIG. 8, it is assumed that the broadcast terminal 500-N activates the HFC-IP network broadcast communication module.

Next, the broadcast terminal 500-N deactivates the UTP-IP broadcast communication module as the communication with the UTP-IP network 200 is interrupted, and uses the activated HFC-IP broadcast communication module to activate the premises broadcasting service. The device 100 transmits a route change notification message (S807, S809). In the content transmission request message, identification information of the broadcast terminal 500-N is recorded.

Then, the UTP-IP broadcast communication module 121 of the premises broadcasting service device 100 receives a route change notification message from the broadcast terminal 500 -N, and the service controller 140 includes the route change notification message. Check the identification information of the broadcast terminal 500-N, and transmit the broadcast content transmitted to the broadcast terminal 500-N using the UTP-IP broadcast communication module 121 based on the identification information. Subsequently, the broadcast communication module 122 is transmitted to the broadcast terminal 500-N (S811).

When the broadcast terminal 500-N receives the broadcast content received through the UTP-IP network 200 through the HFC-IP network 300, the broadcast terminal 500-N recognizes that the access path has been normally changed and accordingly, the UTP-IP network ( In step 200, the HFC-IP network 300 transmits a message notifying that the access path change is completed to the premises broadcasting service device 100 via the HFC-IP network 300 (S813). Then, the service control unit 140 of the premises broadcasting service device 100 deletes the identification information of the broadcasting terminal 500-N recorded corresponding to the identification information of the UTP-IP network 200 from the network table, and the HFC. The identification information of the broadcast terminal 500-N is recorded in the terminal identification information field 38 corresponding to the identification information of the IP network 300 (S817).

Through the procedure of FIG. 8, the broadcast terminal 500 -N switches broadcast paths to broadcast contents from the premises broadcasting service device 100 when a failure occurs in the currently connected broadcast communication network 200, 300, 400, or 600. Receive continuously.

On the other hand, the internal broadcast service device 100 of the present invention is duplexed, the standby broadcast means provides a normal broadcast service to the users even if a failure occurs in the active broadcast means providing the service.

In detail, the first storage unit 931a and the second storage unit 931b store various data, such as a group information table, a network table (see FIG. 3), broadcast content, and the like. In particular, the first storage unit 931a and the second storage unit 931b store the same reserved broadcast data to which time stamp information is added.

The first service control unit 933a of the active broadcasting unit 930a and the second service control unit 933b of the standby broadcasting unit 930b perform the same functions as those of the service control unit 140 described with reference to FIG. 2.

 In addition, the first service control unit 933a and the second service control unit 933b divide the scheduled broadcast content into reserved broadcast data having a predetermined size (for example, 10 Kbytes), and a series of time is divided into the divided broadcast data. Time stamps, which are information, are added and stored in the storage units 931a and 931b, respectively. That is, the duplicated service control units 933a and 933b divide the reserved broadcast content into reserved broadcast data, which is a plurality of playback sections having a predetermined time interval, and sequentially add a series of time stamps to the divided reserved broadcast data. The data is stored in the storage units 931a and 931b, respectively.

The first duplexer 932a included in the active broadcast means 930a continuously transmits the state information of the active broadcast means 930a to the second duplicater 932b of the standby broadcast means 930b. . In detail, the first redundant unit 932a obtains state information of hardware and software included in the active broadcasting unit 930a, and transmits the state information to the second dualizing unit 932b of the standby broadcasting unit 930b. That is, the first redundant unit 932a obtains various states of the active broadcasting means 930a such as CPU state information, memory state information, codec state information, disk state information, and transmits them to the second redundancy unit 932b.

In addition, the second redundant unit 932b of the standby broadcasting unit 930b analyzes the state information of the active broadcasting unit 930a received from the first dualizing unit 932a to determine whether a failure occurs in the active broadcasting unit 930a. It checks whether or not. At this time, when it is determined that the failure has occurred in the active broadcast means 930a, the second redundant unit 932b of the standby broadcast means 930b instructs the service activation to the second service control unit 933b of the standby broadcast means 930b to standby the service. The broadcast means 930b causes the broadcast service to be performed on behalf of the active broadcast means 930a.

FIG. 10 is a flowchart illustrating a method in which a standby broadcast means of a redundant on-premises broadcast service device provides a reserved broadcast service on behalf of an active broadcast means according to another embodiment of the present invention.

Referring to FIG. 10, the input unit 910 of the on-premises broadcasting service device 100 receives a reserved broadcast scenario including group identification information, broadcast time information, and reserved broadcast content, and transmits the reserved broadcast scenario to the active broadcast means 930a. Are transmitted to the first service control unit 933a and the second service control unit 933b of the standby broadcasting unit 930b.

Then, the first service control unit 933a of the active means 930a divides the reserved broadcast content included in the reserved broadcast scenario into reserved broadcast data having a predetermined size (for example, 10 Kbytes), and the plurality of reserved broadcast partitions thus divided. Time stamp information, which is a series of time information, is sequentially added to the data and stored in the first storage unit 931a (S1001). Similarly, the second service control unit 933b of the standby broadcast means 930b divides the reserved broadcast content into reserved broadcast data of a predetermined size, and sequentially stores time stamp information, which is a series of time information, into the divided plurality of reserved broadcast data. In addition, it is stored in the second storage unit 931b (S1003). In other words, the plurality of reserved broadcast data in which the reserved broadcast content is divided into a predetermined size are stored in the first storage unit 931a of the active broadcast means 930a and the second storage unit 931b of the standby broadcast means 930b. The same is stored. In addition, the first service control unit 933a and the second service control unit 933b store the group identification information included in the reserved broadcast scenario in the storage units 931a and 931b, respectively.

With the same data stored in the storage units 931a and 931b, the first service control unit 933a of the active broadcasting unit 930a identifies the group included in the reserved broadcasting scenario when the broadcast time of the reserved broadcasting content arrives. The broadcast terminal identification information corresponding to the information is checked in the group information table of the first storage unit 931a (S1005). In addition, the first service control unit 933a uses the network table of the first storage unit 931a and the extracted broadcast terminal identification information to determine which broadcast communication network (200, 300) designated as the destination of the reserved broadcast. , 400, 600). In FIG. 10, broadcast terminal 1 500-1 and broadcast terminal 2 500-2 are designated terminals as reserved broadcast destinations, and broadcast terminal 1 500-1 is connected to UTP-IP network 200 and broadcasted. It is described that the terminal 2 500-2 is connected to the HFC-IP network 300.

Subsequently, the first service controller 933a sequentially extracts the reserved broadcast data from the first storage unit 931a based on the time stamp information (S1007). Subsequently, the first service control unit 933a uses the broadcast communication modules 921 and 922 to communicate with the broadcast communication networks 200 and 300 to which the corresponding broadcast terminals 500-1 and 500-2 are connected. A session is formed with the terminals 500-1 and 500-2, and the reserved broadcasting data extracted by the broadcasting terminal 500-1.500-2 is sequentially transmitted using the sessions (S1009 and S1011). That is, the first service controller 933a sequentially transmits reserved broadcast data to the broadcast terminal 1 500-1 by using the UTP-IP broadcast communication module 921, and transmits the HFC-IP broadcast communication module 922. The reserved broadcast data is sequentially transmitted to the broadcast terminal 2 500-2.

When the broadcast service is provided by the active broadcast means 930a, the first redundant unit 932a of the active broadcast means 930a obtains state information such as a CPU and a memory of the active broadcast means 930a. The time stamp information of the reserved broadcasting data transmitted from the active broadcasting means 930a is continuously checked. In addition, the first redundant unit 932a continuously transmits the acquired state information of the active broadcast means 930a and the time stamp information of the reserved broadcast data to the second duplicater 932b of the standby broadcast means 930b (S1013). ).

Then, the second redundant unit 932b of the standby broadcast unit 930b continuously receives the state information of the active broadcast unit 930a from the first dual unit 932a, and analyzes the state information to analyze the state information. In operation 930a, it is determined whether a failure has occurred (S1015). When it is determined that the failure occurs in the active broadcasting means 930a, the second redundant unit 932b instructs the active broadcasting means 930a to stop the service and instructs the second service control unit 933b to activate the service (S1017). S1019). In this case, the second redundancy unit 932b transmits the time stamp information last received from the first redundancy unit 932a to the second service control unit 933b.

Then, the first redundant unit 932a instructs the first service control unit 933a to stop the broadcast service and stops the broadcast service from being processed by the active broadcast means 930a. In addition, the second service control unit 933b of the standby broadcasting unit 930b switches from the service standby state to the service activation state, and extracts group identification information designated as the reserved broadcast destination from the second storage unit 931b (S1021). . Subsequently, the second service control unit 933b checks the broadcast terminal identification information corresponding to the group identification information in the group information table of the first storage unit 931a, and then extracts the network table of the second storage unit 931b and the extracted data. The broadcasting terminal 1 (500-1) and the broadcasting terminal 2 (500-2) designated as destinations of the reserved broadcasting are connected to the UTP-IP network 200 and the HFC-IP network 300, respectively, based on the broadcasting terminal identification information. Check (S1023).

Next, the second service controller 933b extracts reserved broadcast data to be transmitted from all the reserved broadcast contents stored in the second storage unit 931b based on the time stamp information received from the second redundant unit 932b (S1025). ). That is, the second service control unit 933b checks the playing section of the reserved broadcasting content provided by the active broadcasting unit 930a based on the time stamp information received from the second duplexing unit 932b, and after the playing section, The reserved broadcast data is extracted from the second storage unit 931b.

Subsequently, the second service control unit 933b sequentially transmits the reserved broadcast data extracted from the second storage unit 931b to the broadcast terminal 1 500-1 using the UTP-IP broadcast communication module 931, and the HFC. The broadcast data is sequentially transmitted to the broadcast terminal 2 500-2 using the IP broadcast communication module 922 (S1027 and S1029).

As described above, when a failure occurs in the active broadcast means 930a, the standby broadcast means 930b detects this and provides a broadcast service to users on behalf of the active broadcast means 930a. In addition, the standby broadcast means 930b does not transmit the reserved broadcast content again from the beginning, but recognizes the playback section of the broadcast content provided through the failed active broadcast means 930a through a timestamp, and after this playback section, Broadcast content to users. Accordingly, the present invention eliminates service delay time due to service takeover and provides viewers with uninterrupted broadcast content even if the broadcast service is duplicated.
