Description

System for triple redundancy broadcasting service

The present invention relates to a broadcast service technology, and more particularly, to a broadcast service triplexing system, which is tripled and provides a stable broadcast service to a user.

Today, various services are provided to users due to the development of communication networks and terminals. Among these, a representative service is a broadcast service. That is, the user receives the broadcast content using a monitor or a speaker and recognizes information such as a main work, a fire, an emergency, and the like through the broadcast content.

In general, a broadcast providing server transmits corresponding broadcast content to a speaker or a monitor which is a destination in real time using a streaming technology. However, when such a broadcast providing server fails, users cannot receive broadcast content, which causes user complaints.

In order to solve this problem, a server redundancy technique is used. The redundancy scheme establishes two servers but designates a first server as an active server and a second server as a standby server. When a failure occurs in an active server providing a service, the standby server recognizes this. How to continue service. However, in the conventional duplexing technique, when the standby server takes over the broadcast service, there is a problem in that the broadcast service is disconnected. That is, in the conventional duplication technique, when the active server fails, the standby server takes a certain time in the process of recognizing it and provides a broadcast service, and during this time, users do not receive the broadcast service.

In addition, in the conventional redundancy technique, there is a situation in which the standby server does not accurately recognize the failure of the active server and thus does not perform a service on behalf of the failed active server. That is, when a failure occurs in the active server, the standby server should perform a broadcast service on behalf of the active server. However, when the standby server does not properly recognize the failure of the active server, the standby server does not provide a broadcast service on behalf of the failed active server, and thus the whole broadcast service is not provided to the user.

The present invention has been proposed to solve such a conventional problem, and provides a seamless broadcasting content to users even when a failure occurs in an active broadcast means providing a broadcast service or a failure occurs simultaneously in an active broadcast means and a standby broadcast means. The purpose is to provide a broadcast service triple system.

In addition, the present invention is to accurately verify the failure of the broadcast service device including the active broadcast means and standby broadcast means, the broadcast service triplex system in which the failure control device itself performs a broadcast service on behalf of the failed broadcast service device There is another purpose to provide.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

In order to achieve the above object, a system for tripleizing a broadcast service provided to a user according to the present invention includes: at least one content providing device for supplying broadcast content; A first broadcast path including a content providing device, a broadcast service device, and an output device connected to each of the content providing device, the output device, and the broadcast service device, and including a content providing device and an output device; Disability control device to form a redundant broadcast path divided into broadcast paths; And active broadcast means for transmitting the broadcast content received from the fault control device to a designated output device and a service state of the active broadcast means by monitoring the service state of the active broadcast means and activated when the fault occurs in the active broadcast means. And a broadcast service device including a standby broadcast means for transmitting broadcast content to a designated output device in place of a means, wherein the failure control device monitors whether the broadcast service device has failed and the broadcast service device normally operates. In operation, the first broadcast path is set as a broadcast service path, the broadcast content is relayed to the broadcast service device, and the broadcast service is performed by the broadcast service device. The second broadcast path is changed to perform a broadcast service on its own in place of the broadcast service device.

Preferably, the failure control device forms a first input signal line with each content providing device, and forms a second input signal line with the broadcast service device so as to correspond to the number of the input signal lines; An input path setting unit forming a third input signal line; An output path forming each output device and a first output signal line, forming the broadcast service device and a second output signal line so as to correspond to the number of the output signal lines, and forming a matrix switching unit and a third output signal line; Setting unit; And the matrix switching unit connecting the third input signal line to the third output signal line when a failure occurs in the broadcast service device.

The first broadcast path extends through the first input signal line, the second input signal line, the second output signal line, and the first output signal line, and the second broadcast path includes the first input signal. Extends through a signal line, the third input signal line, the third output signal line, and the first output signal line.

According to the present invention, when a failure occurs in the active broadcast means, the standby broadcast means, which is in the standby state of the service, immediately recognizes the failure and continuously outputs the broadcast content through the same input path and output path used by the active broadcast means. There is an advantage of eliminating delays and providing users with seamless broadcast content.

In addition, the present invention has an advantage of providing a more stable broadcast service to users by detecting when a failure occurs in the output line of the active broadcast means and the standby broadcast means, and by performing the broadcast service through the failure control device.

In addition, the present invention has the advantage of further improving the stability of the entire broadcasting system by allowing the failure control apparatus to verify the failure of the active broadcasting means not recognized by the standby broadcasting means.

Referring to FIG. 2, the broadcast service device 200 includes an input port 210, an output port 220, a communication unit 230, an active broadcaster 240, and a standby broadcaster 250. In addition, the failure control apparatus 300 may include an input path setting unit 310, an output path setting unit 320, a matrix switching unit 330, a storage unit 340, a control unit 350, and a failure detection unit 360.

That is, the input path setting unit 310 includes a plurality of input ports and output ports, and a cable extending from the content providing apparatus 100 -N is connected to each of the plurality of input ports, thereby providing an input path setting unit 310. ) Forms independent input signal lines IN1a to IN3a for each content providing device 100 -N. For example, the input path setting unit 310 forms an input signal line of the content providing device 1 (100-1) and IN1a, and forms an input signal line of the content providing device 2 (100-2) and IN2b.

In addition, the input path setting unit 310 inputs each input signal line IN1a to IN3a formed with the content providing device 100 -N to the matrix switching unit 330 and the input port 210 of the broadcast service device 200.

That is, the input path setting unit 310 corresponds to the number of the input signal lines IN1a to IN3a formed with the content providing device 100 -N, and the input ports of the matrix switching unit 330 and the broadcast service device 200. Reference numeral 210 and input signal lines IN1b to IN3b and IN1c to IN3c are formed, respectively. At this time, the input path setting unit 310 opens only one of the input signal lines connected to the input port 210 of the matrix switching unit 330 or the broadcast service device 200 based on the control signal of the control unit 350. The other is unhappy. That is, the input path setting unit 310 selects the input signal lines IN1a to IN3a formed with the content providing device 100 -N, and the input signal lines IN1c to IN3c formed with the matrix switching unit 330 or the broadcast service device. And selectively connected to the input signal lines IN1b to IN3b formed at 200.

That is, the output path setting unit 320 includes a plurality of output ports, and a cable extending from the output device 400 -N is connected to each of the plurality of output ports, so that each output device 400 -N is connected to the output path setting unit 320. Independent output signal lines OUT1a to OUT4a are formed. For example, the output path setting unit 320 forms an input signal line of the output device 1 (400-1) and OUT1a, and forms an output signal line of the output device 2 (400-2) and OUT2a.

In addition, the output path setting unit 320 outputs the respective output device 400 -N and the respective output signal lines OUT1a to OUT4a formed by the matrix switching unit 330 and the output port of the broadcast service device 200. To 220). At this time, the output path setting unit 320 is based on the control signal of the control unit 350, the output signal line (OUT1c ~ OUT4c) connected to the matrix switching unit 330 or the output port 220 of the broadcast service device 200 Only one of the output signal lines OUT1b to OUT4b connected to is opened and the other is turned off. That is, the input path setting unit 310 outputs the output signal lines OUT1a to OUT4a formed with the output device 400 -N, and output signal lines OUT1c to OUT4c or the broadcast service device connected to the matrix switching unit 330. It is selectively connected to the output signal line OUT1b to OUT4b connected to the output port 220 of the 200.

The matrix switching unit 330 forms an input path setting unit 310 and a plurality of input signal lines IN1c to IN3c, and forms an output path setting unit 320 and a plurality of output signal lines OUT1c to OUT4c. In this case, the input signal lines IN1c to IN3c and the output signal lines OUT1c to OUT4c are selectively connected. That is, the matrix switching unit 330 electrically connects the specific input signal lines IN1c to IN3c with the specific output signal lines OUT1c to OUT4c based on the control signal of the controller 350.

The system according to the present invention has a connection structure of a plurality of input signal lines (IN1a to IN3a, IN1b to IN3b, IN1c to IN3c) and output signal lines (OUT1a to OUT4a, OUT1b to OUT4b, and OUT1c to OUT4c). The redundant broadcasting path is established through the connection control between the input signal line and the output signal line. In other words, the first broadcast path is a service path in a normal service state and includes a broadcast service device 200 and input signal lines IN1b to IN3b and output signal lines OUT1b to OUT4b formed. That is, the first broadcast path input signal lines IN1a to IN3a formed between the content providing device 100 -N and the input path setting unit 310, an input formed between the input path setting unit 310 and the input port 210. Output signal lines OUT1b to OUT4b formed between the signal lines IN1b to IN3b, the output port 220 and the output path setting unit 320, and output signal lines OUT1a to between the output path setting unit 320 and the output device. It has a connection structure including OUT4a).

In addition, the second broadcast path is a service path in a state in which the broadcast service device 200 operates abnormally, and includes the input signal lines IN1c to IN3c and the output signal lines OUT1c to OUT4c formed with the matrix switching unit 330. It includes. That is, the second broadcast path is formed between the input signal lines IN1a to IN3a formed between the content providing device 100 -N and the input path setting unit 310, the input path setting unit 310, and the matrix switching unit 330. Output signal lines OUT1c to OUT4c formed between the input signal lines IN1c to IN3c, the matrix switching unit 330 and the output path setting unit 320, and output signal lines formed between the output path setting unit 320 and the output device ( It has a connection structure including OUT1a to OUT4a).

The storage unit 340 stores the matrix table. This matrix table is equally stored in the active broadcast means 240 and the standby broadcast means 250. In addition, the matrix table is equally stored in each of the storage unit 340, the active broadcasting unit 240, and the standby broadcasting unit 250 of the failure control apparatus 300, and when changed, the changed information is stored in the storage unit ( 340, the active broadcast means 240 and the standby broadcast means 250 are equally reflected to each other. That is, the matrix table of the storage unit 340, the matrix table of the active broadcaster 240, and the matrix table of the standby broadcaster 250 are synchronized with each other.

3 is a diagram illustrating a matrix table according to an embodiment of the present invention.

Referring to FIG. 3, the storage unit 340 stores a matrix table in which output signal lines OUT1 to OUT4 are recorded corresponding to the input signal lines IN1 to IN3. In other words, data for determining to which output signal lines OUT1 to OUT4 the broadcast content received from each of the input signal lines IN1 to IN3 is stored in the matrix table of the storage unit 340. In FIG. 3, the number '1' represents an ON state, and the number '0' represents an OFF state. In FIG. 3, the broadcast content input from the input signal line 1 (IN1) is output to the output signal line 3 (OUT3), and the broadcast content input from the input signal line 3 (IN3) is output to the output signal line 1 (OUT1). .

The controller 350 controls the input / output paths of the input path setting unit 310 and the output path setting unit 320, and also controls the connection structure of the matrix switching unit 330. In detail, when a normal broadcast service is performed in the broadcast service device 200, the controller 350 includes input signal lines IN1b to IN3b and output signal lines OUT1b to OUT4b formed with the broadcast service device 200. The first broadcast path is set as a broadcast service path.

In addition, when the controller 350 receives the failure occurrence information of the broadcast service device 200 from the failure detector 360, the control unit 350 forms an input signal line IN1c to IN3c and an output signal line OUT1c formed with the matrix switching unit 330. A second broadcast path including ˜OUT4c) is set as a broadcast service path. In addition, the controller 350 checks the matrix table of the storage unit 340 for the output signal lines designated as the output paths of the respective input signal lines, and then controls the matrix switching unit 330 based on the result of the input signal lines and the output signals. Allow lines to be interconnected. For example, when the matrix table illustrated in FIG. 3 is stored in the storage unit 340, the control unit 350 is connected to the input signal line 1c (IN1c) with the output signal line 3c (OUT3c), and the input signal line 2c (IN2c). Is connected to the output signal line 4c (OUT4c) and simultaneously controls the matrix switching unit 330 so that the input signal line 3c (IN3c) is connected to the output signal line 1c (IN1c).

The failure detection unit 360 continuously checks whether the active broadcast means 240 and the standby broadcast means 250 of the broadcast service device 200 are faulty. Specifically, the failure detecting unit 360 receives status information from each of the active broadcasting means 240 and the standby broadcasting means 250, and analyzes the status information to determine whether a failure occurs in the broadcast service device 200. As a result of the determination, when it is determined that a failure occurs in both the active broadcast means 240 and the standby broadcast means 250, the controller 350 reports a failure of the broadcast service device 200.

In addition, the failure detection unit 360 is connected to each of the input signal lines IN1b to IN3b formed between the input path setting unit 310 and the input port 210 of the broadcast service device 200, and also output path setting unit ( Each output signal line OUT1b to OUT4b formed between the 320 and the output port 220 of the broadcast service device 200 is connected. Thus, the failure detection unit 360 having a structure connected to the corresponding input signal lines IN1b to IN3b and the output signal lines OUT1b to OUT4b monitors whether broadcast content flows into each of the input signal lines IN1b to IN3b. When the broadcast content flows from the corresponding input signal lines IN1b to IN3b, the output signal lines OUT1b to OUT4b designated as output paths of the input signal lines IN1b to IN3b are checked in the matrix table of the storage unit 340. do.

 In addition, the failure detection unit 360 checks whether a signal level above a threshold value is detected in the identified output signal lines OUT1b to OUT4b and, if detected, broadcast content introduced through the input signal lines IN1b to IN3b. Is determined by the active broadcast means 240 of the broadcast service device 200 to the normally designated output device (400-N). On the other hand, when the signal level higher than the threshold value is not detected in the identified output signal lines OUT1b to OUT4b, the failure detector 360 recognizes the failure of the active broadcast means 240 accurately. If not, and transmits a message indicating the activation of the service to the standby broadcast means 250 to the broadcast service device 200.

On the other hand, after detecting that the standby broadcast means 250 is performing the broadcast service, the failure detection unit 360 does not leak the broadcast content through the designated output signal lines OUT1b to OUT4b. It is determined that there is a failure in the output port 220 or the output signal lines OUT1b to OUT4b connected to the output port 220, and reports the failure of the broadcast service device 200 to the controller 350.

The input port 210 of the broadcast service device 200 forms an input path setting unit 310 and input signal lines IN1b to IN3b, and activates the broadcast content received through the input signal lines IN1b to IN3b. The broadcast means 240 and the standby broadcast means 250, respectively.

The output port 220 forms an output path setting unit 320 and a plurality of output signal lines OUT1b to OUT4b and performs a function of leaking broadcast contents through the output signal lines OUT1b to OUT4b.

The communication unit 230 performs a function of communicating with the failure detecting unit 360 of the failure control device 300, and in particular, periodically or in real time, the status information of the active broadcaster 240 and the status information of the standby broadcaster 250. Report to the failure detection unit 360 as.

The input port 210, the output port 220, and the communication unit 230 are shared by the active broadcaster 240 and the standby broadcaster 250.

The active broadcast means 240 of the broadcast service device 200 primarily performs a function of providing a broadcast service to a user. Specifically, the active broadcaster 240 stores the matrix table (see FIG. 3), and when the broadcast content is received from the input port 210, checks the input signal lines IN1b to IN3b into which the broadcast content is introduced. The output signal lines OUT1b to OUT4b designated as output paths of the input signal lines IN1b to IN3b are checked in a matrix table stored therein. In addition, the active broadcast means 240 leaks the broadcast content to the identified output signal lines OUT1b to OUT4b using the output port 220. Meanwhile, the active broadcaster 240 collects state information of its hardware (ie, a controller, a memory, a codec, etc.) and transmits the state information to the standby broadcaster 250, and also uses a communication unit 230 to detect a failure ( 360).

The standby broadcast means 250 is set to a service standby state, and continuously monitors whether the active broadcast means 240 is disturbed by analyzing state information received from the active broadcast means 240. In addition, the standby broadcast means 250 stores a matrix table (refer to FIG. 3). When it is determined that the active broadcast means 240 has failed, the standby broadcast means 250 is activated to perform a broadcast service on behalf of the active broadcast means 240. At this time, the standby broadcast means 250 receives the broadcast content through the input port 210 and checks the input signal lines IN1b to IN3b through which the broadcast content is flowing through the input port 210, and the input signal line. Check the matrix table in which the output signal lines OUT1b to OUT4b designated as the output paths of (IN1b to IN3b) are stored in-house. In addition, the standby broadcast means 250 leaks the broadcast content to the identified output signal lines OUT1b to OUT4b using the output port 220. Similarly, the standby broadcast means 250 collects the state information of its hardware (ie, the controller, memory, codec, etc.), and transmits the state information to the failure detection unit 360 using the communication unit 230, When the service is switched from the standby state to the service activation state, the service switching information is also transmitted to the failure detection unit 360.

4 to 9, the information recorded in the matrix table is the same as that of FIG. 2, and it is assumed that broadcast content is supplied only from the content providing apparatus 1 100-1.

4 is a flowchart illustrating a method of performing a broadcast service on behalf of an active broadcast means by a standby broadcast means according to an embodiment of the present invention.

Referring to FIG. 4, the content providing device 1 (100-1) supplies broadcast content such as audio and video to the failure control device 300 through the input signal line 1a (IN1a) formed with the failure control device 300. (S401).

Then, the input path setting unit 310 of the failure control device 300 receives the broadcast content through the input signal line 1a (IN1a), and through the input signal line 1b (IN1b) formed with the broadcast service device 200. The broadcast content is transmitted to the input port 210 of the broadcast service device 200 (S403 and S405). At this time, the control unit 350 of the failure control device 300 recognizes that the broadcast service device 200 is operating normally, and the input signal lines IN1b to IN3b and the output signal lines formed with the broadcast service device 200 ( A first broadcast path including OUT1b to OUT4b) is set as a broadcast service path. That is, the control unit 350 controls the signal line of the input path setting unit 310 when the failure control device 300 is performing the broadcast service normally, and the input signal lines a (IN1a to IN3a) and the input signal line b ( Connect IN1b to IN3b, respectively, and connect output signal lines a (OUT1a to OUT4a) and output signal lines b (OUT1b to OUT4b), respectively. Accordingly, the signal lines IN1a and IN1b, IN2a and IN2b, IN3a and In3b, OUT1a and OUT1b, OUT2a and OUT2b, OUT3a and OUT3b, OUT4a and OUT4b are connected to each other in FIG. 2.

Next, the input port 210 of the broadcast service device 200 delivers the broadcast content received through the input signal line 1a (IN1a) to the active broadcast means 240 and the standby broadcast means 250, respectively. Then, the active broadcasting means 240 set to the service activation state confirms through the input port 210 that the broadcast content is received through the input signal line 1b (IN1b), and outputs the output path of the input signal line IN1b. In step S407, the self-stored matrix table confirms that the designated output signal line is 'OUT3'. Next, the active broadcaster 240 leaks the broadcast content to the identified output signal line OUT3b using the output port 220 (S409).

Then, the output path setting unit 320 of the failure control device 300 receives the broadcast content through the output signal line 3b (OUT3b), and to the output signal line 3a (OUT3a) connected to the output signal line 3b (OUT3b). By relaying the broadcast content, the broadcast content is finally transmitted to the output device 3 (400-3) (S411).

FIG. 5 is a diagram illustrating an input signal line and an output signal line on which a broadcast service is to be processed through an active broadcasting means according to an embodiment of the present invention.

As shown in FIG. 5, the broadcast content supplied from the content providing apparatus 100 -N includes an input path setting unit 310, an input port 210, an active broadcasting means 240, an output port 220, Finally, the output path setting unit 320 arrives at the output device 3 (400-3). Dotted lines shown in FIG. 5 are route information of broadcast content provided by the content providing apparatus 1 (100-1). In other words, if the active broadcast means 240 of the broadcast service device 200 does not occur and the broadcast service is being performed by the active broadcast means 240, the content providing device 100 -N is supplied. The broadcast content is transmitted to the active broadcast means 240 through the input path setting unit 310, and the active broadcast means 240 transmits the broadcast content by designating the output path of the broadcast content.

While the broadcast service is in progress by the active broadcast means 240, the active broadcast means 240 continuously transmits its status information to the standby broadcast means 250 (S413). Then, the standby broadcast means 250 analyzes the state information of the received active broadcast means 240, and determines whether or not a failure occurs in the active broadcast means 240. When the standby broadcast means 250 determines that a failure has occurred in the active broadcast means 240 as a result of the failure determination, it instructs the active broadcast means 240 to deactivate the service to stop the broadcast service in the active broadcast means 240. In addition, it switches its state from the service deactivation state to the service activation state (S415, S417, S419).

Next, the standby broadcast means 250 confirms the inflow path (that is, the path of the input signal line) of the broadcast content received through the input port 210, and is designated as the output path of the identified inflow path IN1b. Check that the output signal line is 'OUT3' in a matrix table stored therein (S421). Subsequently, the standby broadcast means 250 leaks the broadcast content to the identified output signal line OUT3b using the output port 220 (S423). Then, the output path setting unit 320 of the failure control device 300 receives the broadcast content through the output signal line 3b (OUT3b), and to the output signal line 3a (OUT3a) connected to the output signal line 3b (OUT3b). By relaying the broadcast content, the broadcast content is finally transmitted to the output device 3 (400-3) (S425). In addition, the standby broadcast means 250 notifies the failure detection unit 360 of the failure control device 300 by using the communication unit 230 that the active broadcast means 240 is a failure occurs in the broadcast service itself. Accordingly, the failure control apparatus 300 recognizes that the broadcast service is in progress by the standby broadcast means 250.

6 is a diagram illustrating an input signal line and an output signal line formed when a broadcast service is performed through a standby broadcast means according to an embodiment of the present invention.

As shown by a dotted line in FIG. 6, the broadcast content supplied from the content providing device 100 -N includes an input path setting unit 310, an input port 210, a standby broadcast means 250, and an output port 220. ), And finally arrives to the output device 3 (400-3) via the output path setting unit 320. That is, when a failure occurs in the active broadcast means 240 of the broadcast service device 200, the broadcast service is stopped by the active broadcast means 240, and the standby broadcast means 250 is operated by the active broadcast means 240. The broadcast service is performed using the same input / output signal lines IN1b and OUT3b.

7 is a flowchart illustrating a method of activating a standby broadcast means by detecting a failure of an active broadcast means in a failure control apparatus according to an embodiment of the present invention.

Of the reference numerals of FIG. 7, the same steps as those of FIG. 4 are performed in the same manner as the description with reference to FIG. 4. Therefore, in the description with reference to FIG. Omit.

The active broadcast means 240 transmits the broadcast content supplied from the content providing device 1 (100-1) to the output device 3 (400-3) using the output signal line 3b (OUT3b) (S401, S403, S405, S407, S409, S411).

At this time, the failure detection unit 360 of the failure control device 300, whether the broadcast content is flowing from each input signal line (IN1b, IN2b, IN3b) formed between the input path setting unit 310 and the input port 210. The system monitors whether the broadcast content is flowing from the input signal line 1b IN1b as a result of the monitoring (S713). Next, the failure detection unit 360 confirms in the matrix table of the storage unit 340 that the designated output path of the input signal line 1b (IN1b) is the output signal line 3b (OUT3b) (S715). Subsequently, the failure detection unit 360 checks whether the broadcast content is leaked through the identified output signal line 3b (OUT3b), and if it is leaked, by the active broadcast means 240 of the broadcast service device 200. It is determined that the broadcast service is normally performed (S717). At this time, the failure detection unit 360 measures the signal level of the output signal line 3b (OUT3b), and when the measured signal level is equal to or greater than a predetermined value, broadcast content is normally leaked to the output signal line 3b (OUT3b). You can judge that there is.

On the other hand, when the broadcast content is not leaked through the identified output signal line 3b (OUT3b), the failure detector 360 determines that a failure occurs in the active broadcast means 240 (S719). That is, when the broadcast content is not leaked out through the identified output signal line 3b (OUT3b), the failure detection unit 360 does not properly recognize the failure by the active broadcast means 240 and broadcasts the broadcast content. It is determined that the service has not been acquired. Subsequently, the failure detection unit 360 transmits the deactivation message of the active broadcaster 240 and the activation message of the standby broadcaster 250 to the broadcast service device 200 (S721 and S723).

Then, the active broadcaster 240 receives the deactivation message through the communication unit 230, and stops transmitting the broadcast content according to the deactivation message. In addition, the standby broadcast means 250 receives the activation message through the communication unit 230, and switches from the service standby state to the service activation state in response to the activation message (S725). Subsequently, the activated standby broadcast means 250 checks an inflow path (that is, a path of an input signal line) of broadcast content received through the input port 210, and outputs the output path of the identified inflow path IN1b. The self-stored matrix table confirms that the designated output signal line is 'OUT3' (S727). Subsequently, the standby broadcast means 250 leaks the broadcast content to the checked output signal line OUT3b using the output port 220 (S729). Then, the output path setting unit 320 of the failure control device 300 receives the broadcast content through the output signal line 3b (OUT3b), and to the output signal line 3a (OUT3a) connected to the output signal line 3b (OUT3b). By relaying the broadcast content, the broadcast content is finally transmitted to the output device 3 (400-3) (S731). As shown in FIG. 6, the broadcast content is finally passed through the input path setting unit 310, the input port 210, the standby broadcasting means 250, the output port 220, and the output path setting unit 320. To output device 3 (400-3).

On the other hand, the standby broadcast means 250 notifies the failure detection unit 360 of the failure control device 300 that the active broadcast means 240 is in progress because he is broadcasting service, accordingly the failure control device The 300 recognizes that the broadcast service is in progress by the standby broadcast means 250.

8 is a flowchart illustrating a method of performing a broadcast service on behalf of a broadcast service device in a failure control device according to an embodiment of the present invention.

Referring to FIG. 8, the content providing device 1 (100-1) supplies broadcast content such as audio and video to the failure control device 300 through the input signal line 1a (IN1a) formed with the failure control device 300. (S801).

Then, the input path setting unit 310 of the failure control device 300 receives the broadcast content through the input signal line 1a (IN1a), and through the input signal line 1b (IN1b) formed with the broadcast service device 200. The broadcast content is transmitted to the input port 210 of the broadcast service device 200 in operation S803. At this time, the controller 350 of the failure control apparatus 300 recognizes that the broadcast service device 200 is operating normally, and sets the broadcast path to the first broadcast path including the broadcast service device 200. That is, the controller 350 controls the signal lines of the input path setting unit 310 to control the input signal lines 1a, 2a, and 3a (IN1a, IN2a, and IN3a) when the failure control apparatus 300 normally performs a broadcast service. And input signal lines 1b, 2b, and 3b (IN1b, IN2b, and IN3b), respectively, and output signal lines 1a, 2a, 3a, and 4a (OUT1a, OUT2a, OUT3a, and OUT4a) and output signal lines 1b, 2b, and 3b. Connect 4b (OUT1b, OUT2b, OUT3b, OUT4b) respectively.

Next, the standby broadcast means 250 that performs a broadcast service on behalf of the failed active broadcast means 240 receives the broadcast content through the input port 210, and the broadcast content is input signal line 1b (IN1b). Check through the input signal path of the input port 210 that is received through. Subsequently, the standby broadcast means 250 checks in a matrix table stored therein that an output signal line designated as an output path of the input signal line 1b IN1b is 'OUT3' (S805). Next, the active broadcaster 240 leaks the broadcast content to the identified output signal line 3b (OUT3b) using the output port 220 (S807).

Then, the output path setting unit 320 of the failure control device 300 receives the broadcast content through the output signal line 3b (OUT3b), and to the output signal line 3a (OUT3a) connected to the output signal line 3b (OUT3b). By relaying the broadcast content, the broadcast content is finally transmitted to the output device 3 (400-3) (S809). In addition, the failure detection unit 360 of the failure control device 300 monitors whether the broadcast content is flowing for each of the input signal lines IN1b, IN2b, and IN3b, and broadcasts the result in the input signal line 1b (IN1b). It is confirmed that the content is flowing (S811).

Next, the failure detection unit 360 confirms to the matrix table of the storage unit 340 that the designated output path of the input signal line 1b (IN1b) is the output signal line 3b (OUT3b) (S813). Subsequently, the failure detection unit 360 checks whether the broadcast content is leaked through the identified output signal line 3b (OUT3b), and if it is leaked, by the standby broadcast means 250 of the broadcast service device 200. It is determined that the broadcast service is normally performed (S815). At this time, the failure detection unit 360 measures the signal level of the output signal line 3b (OUT3b), and when the measured signal level is equal to or greater than a predetermined value, broadcast content is normally leaked to the output signal line 3b (OUT3b). You can judge that there is.

On the other hand, when the broadcast content is not leaked out through the identified output signal line 3b (OUT3b), the failure detector 360 detects that the standby broadcast means 250 has its own fault or failure in the output signal line 3b (OUT3b). That is, it is determined that there is a line disturbance (S817). That is, when the standby broadcasting unit 250 is activated, the failure detecting unit 360 broadcasts the broadcast content flowing through the input signal line 1b (IN1b) when it is not leaked through the output signal line 3b (OUT3b). It is determined that there is a failure in the entire service apparatus 200.

Subsequently, the failure detection unit 360 transmits the deactivation message of the standby broadcast means 250 to the broadcast service device 200 to stop the broadcast service from being performed by the standby broadcast means 250 (S819). In addition, the failure detection unit 360 reports a failure of the broadcast service device 200 to the control unit 350. Then, the controller 350 controls the input path setting unit 310 and the output path setting unit 320 to control the input signal lines IN1c to IN3c and the output signal lines OUT1c to OUT4c formed with the matrix switching unit 330. In operation S821, the second broadcast path including a) is reset to the broadcast service path. That is, the controller 350 controls the input path setting unit 310 to input the input signal lines 1c, 2c, and 3c (IN1c, IN2c, and IN3c) to the input signal lines 1a, 2a, and 3a (IN1a, IN2a, and IN3a), respectively. And output path signals 1c, 2c, 3c, and 4c (OUT1c, OUT2c, and OUT3c) to the output signal lines 1a, 2a, 3a, and 4a (OUT1a, OUT2a, OUT3a, and OUT4a) by controlling the output path setting unit 320. , OUT4c) is connected to change the broadcast path from the first broadcast path to the second broadcast path.

Next, the controller 350 checks the matrix table of the storage unit 340 for the output signal lines designated as the output paths of the respective input signal lines, and then assigns the input signal lines IN1c, IN2c, and IN3c based on the check result. A connection structure of the matrix switching unit 330 is set to be connected to the output signal lines OUT1c, OUT2c, OUT3c, and OUT4c (S823). That is, the controller 350 connects the input signal line 1c (IN1c) to the output signal line 3c (OUT3c) and the input signal line 2c (IN2c) to the output signal line 4c (OUT4c) based on the matrix table of FIG. In addition, the switch of the matrix switching unit 330 is controlled so that the input signal line 3c (IN3c) is connected to the output signal line 1c (OUT1c) (see the internal connection structure of 330 of FIG. 9).

When the input / output path is reset by the controller 350, the matrix switching unit 330 receives the broadcast content flowed through the input signal lines IN1c, IN2c, and IN3c, and inputs the corresponding input signal lines IN1c, IN2c, and IN3c. By outputting to the output signal lines (OUT1c, OUT2c, OUT3c, OUT4c) connected to the corresponding, and delivers the content to the specified destination (S825). That is, the matrix switching unit 330 outputs the broadcast content supplied from the content providing device 1 (100-1) through the input signal line 1c (IN1c) to the output signal line 3c (OUT3c) connected to the input signal line 1c (IN1c). The broadcast content is finally delivered to the output device 3 (400-3).

In summary, the failure control apparatus 300 determines whether the standby broadcast means 250 that performs a broadcast service on behalf of the failed active broadcast means 240 determines whether or not the standby broadcast means 250 fails. The broadcast service path is changed from the first broadcast path to the second broadcast path. In addition, the failure control apparatus 300 controls the connection structure of the matrix switching unit 330 so that the input signal line is connected to the designated output signal line, so that the broadcast content reaches the designated destination.

9 is a diagram illustrating an input signal line and an output signal line formed when a failure control apparatus performs a broadcast service according to an embodiment of the present invention.

As shown in FIG. 9, the broadcast content supplied from the content providing apparatus 100 -N is finally passed through the input path setting unit 310, the matrix switching unit 330, and the output path setting unit 320. Arrive at the specified output device 400-N. 9, the broadcast content provided by the content providing device 100-1 is output through the input signal lines IN1a and IN1c and the output signal lines OUT3c and OUT3a in sequence. 3) is delivered. That is, when a failure occurs in both the active broadcast means 240 and the standby broadcast means 250 of the broadcast service device 200, the broadcast service by the broadcast service device 200 is stopped, and the failure control device 300 broadcasts. The path is changed from the first broadcast path to the second broadcast path, and the broadcast service is smoothly provided to the user through the second broadcast path.
