Next, a broadcasting method according to an exemplary embodiment of the present disclosure will be described. The broadcasting method of the present embodiment can be implemented using the terminal 100 and the broadcasting apparatus 1 having the above-described configuration.

FIG. 3 is a flowchart showing a rough procedure of a broadcasting method according to an example of the present disclosure. For example, when an emergency broadcast is transmitted in the event of an emergency disaster in a building such as a business building or a hotel, For example,

In the normal broadcast mode, the display device 200 receives a digital broadcast signal transmitted from a broadcasting company through a digital broadcasting network such as a terrestrial wave, a satellite, and a cable through the head end system 300. The display device 200 classifies received digital broadcasting signals into channels, decodes them, converts the received digital broadcasting signals into audible and audible signals, and transmits them through speakers and a screen.

3, when an emergency signal is received at the terminal 100 through the network 400 due to an emergency such as a fire, an earthquake or a terrorist attack, the controller 10 of the terminal 100 The display device driver 50 controls the display device 200 to switch from the normal broadcast mode to the emergency broadcast mode in accordance with the set emergency broadcast control logic. The mode switching control signal is transmitted to the display device 200 through a serial interface such as RS232C. In addition, the multimedia player application is executed to reproduce the contents for emergency broadcasting stored in advance in the storage unit 30 and to display the contents on the display device 200 through the display unit 40. The reproduced contents are integrated with audio and video signals and transmitted to the display device 200 through a multimedia interface such as an HDMI port.

When the mode switching signal is received, the display device 200 switches the normal broadcast mode to the emergency broadcast mode. Accordingly, the transmission of the digital broadcast is stopped, and the emergency broadcast received through the HDMI port is transmitted through the speaker and the screen.

The presentation of the emergency broadcast content can be repeated continuously until a termination signal is received. When the emergency signal is received and the display device 200 is turned off, the emergency broadcast mode can be executed after switching the display device 200 to " on " via the display device driver 50 .

Here, the terminal 100 according to the present disclosure sends out the contents for emergency broadcasting according to the web-based control logic. For example, an identifier (URI) or an address (URL) for transmitting the contents for emergency broadcasting stored in advance in the storage unit 30 is set and an HTTP query (HTTP: // URI + METHOD) based on the RESTful API is used So that the broadcast data can be transmitted to the multimedia player and reproduced. Therefore, it is possible to easily display the emergency broadcast by calling and reproducing the contents stored in the terminal 100 in advance in a web-based or IP-based manner without using an RF channel for emergency broadcasting. According to this configuration, since it is possible to store a plurality of different contents for emergency broadcasting according to the respective emergency situations, the location of occurrence, etc. in each terminal 100 and display it separately according to the occurrence situation, There is a big difference between and.

In the conventional terminal, for example, when it is necessary to guide the evacuation route of each user differently according to the place where each user is located in the building such as a business building of a company, the kind of emergency situation, No measures were taken. In addition, since a method of forcibly switching a channel at the time of occurrence of an event is used, in order to realize a user-tailored individual announcement according to the place where each user is located, an RF channel should be added as many as the number of offices or users However, such a channel expansion is uneconomical and unrealizable because it requires a lot of frequencies.

On the other hand, according to the terminal 100 according to the present disclosure, it is possible to execute a web-based or IP-based control logic without recourse to an RF channel at the time of emergency broadcasting, For example, a plurality of contents guiding the optimal evacuation route may be prepared in advance according to the current position of the user, the type of emergent situation, the location of occurrence of the emergency situation, and stored in each terminal 100, Therefore, it is possible to guide the optimal evacuation route according to each emergency situation where the person lives, so that the risk of a safety accident can be significantly reduced compared to the conventional case.

4 (a) to 4 (f) are diagrams schematically showing an example of contents for emergency broadcasting transmitted in the emergency broadcasting mode. For example, when a fire occurs in the office of a business office building or a hotel room As an example.

When a fire occurs in the area, for example, both the terminal 100 provided in the room 101 and the terminal 100 provided in the room 103 are all connected to the nearest 1 It is common to guide the route A for escaping to the floor exit.

As shown in FIG. 4 (b), when a fire occurs in front of Room 102 between Room 101 and Room 103, the user of Room 103 can safely use the path (A) However, since the user of the room 101 may be exposed to the fire generated in the room 102 in the process of evacuation through the path A, the user A may not be exposed to the fire risk 101 Can not be the path of.

In this case, the regional fire prevention and disaster prevention system transmits the fire occurrence position information sensed by the sensor or the like together with the emergency signal, and the 101 room terminal 100, which receives the fire emergency position signal, After executing the routine for confirming whether or not the vehicle is located on the route A, if it is confirmed that the vehicle is located on the route A, as shown in Fig. 4 (c) The emergency broadcast content is transmitted through the display device 200 to guide the route B for escaping to the destination. At this time, the fire occurrence position sensed by the sensor or the like as shown in Fig. 4 (c) can be displayed on the contents.

The 103 room terminal 100 also executes a routine for confirming whether or not the fire occurrence position is located on the route A. [ In this case, since the fire occurrence position is not located on the path A, the 103 room terminal 100 can notify the user of the 103 room by using the path (A) as shown in FIG. 4 (c) You can guide them through the building to escape.

However, if the fire occurrence position is located on the route A as shown in FIG. 4 (d), the 103 room terminal 100 notifies the user of the room 103 of the route B ' And escorted through the emergency stairs to the 2-story emergency exit.

As described above, according to the terminal 100 of the present disclosure, a plurality of contents guiding the optimum evacuation route are prepared and stored in advance according to the current location of the user, the type of emergency situation, the location of occurrence, It is possible to individually select and transmit each content for each terminal, thereby greatly reducing the risk of an accident. In the present embodiment, the fire situation has been described as an example. However, in order to prevent an emergency such as an earthquake, a typhoon, an explosion, a collapse of the building, terrorism, .

The emergency broadcast content may be stored in an external storage medium such as a USB or SD card and may be connected to the input / output terminal unit 60 of the terminal 100 and copied to the storage unit 30 or may be copied from the management server 500 to the network 400 To the terminal 100 and store the same in the storage unit 30 in advance.

On the other hand, in emergency broadcasting, it is important to notify the user who watches and listens to the emergency broadcast accurately along with voice and visual evacuation route, but it is difficult to achieve the purpose with the general 30 frame video emergency broadcasting. In addition, since the voice is not supported when the image is displayed only, this also can not achieve the purpose.

The broadcasting method according to the present exemplary embodiment provides an emergency broadcasting method in which a moving picture expression algorithm of a slide method overcomes both drawbacks of an image method and disadvantages of a moving picture method. The flow of the algorithm is as follows.

1) Create an image file

Depending on the complexity of the evacuation path, there can be one or several image files. 4 (d) to 4 (f), the emergency evacuation route, the emergency evacuation route, etc. can be made into a plurality of image files to produce the emergency broadcast contents.

2) Convert MP4 image file of image file

The converted image corresponds to the number of image files such as 1 frame / second, 2 frames / second, or several frames / second.

3) With voice

The image file is repeated until the end point of the voice file, and when the attachment of the voice file is finished, it is created as one conversion file. It is implemented as a GUI tool by applying algorithms based on the FFMPEG multimedia framework.

The prepared emergency broadcast content is distributed to the terminal and the player of the terminal displays the emergency broadcast content on the display device upon receiving the emergency signal. There are two types of display methods of the terminal: a single loop operation or an infinite loop operation until a termination signal is received. However, in an infinite loop application, there is a problem that a time gap occurs when the file is completely displayed and the file is recalled again. To solve this problem, the following algorithm is applied in the present disclosure.

1) Since a delay occurs when a file is directly read from the storage unit, it is designed as a FIFO structure using a RAM and is piped from the storage unit to the RAM. The FIFO structure is scalable.

2) In the two-instance structure, the first instance is the execution mode and the other instance is the standby mode. The second instance begins to pass the copy file to the FIFO just before the first instance ends. This means that when the first instance no longer has a file to read, it exits the first instance and exposes the file read from the second instance.

According to the broadcasting method of the present disclosure using this algorithm, it is possible to prevent time gap between a file and a file from being generated when an infinite loop is executed, while providing an image and a voice together, so that emergency broadcasting can be naturally displayed without interruption.

On the other hand, in the broadcasting method according to the present exemplary embodiment, the emergency signal can be transmitted to the respective terminals 100 through the network 400 from the sensing means 600 such as a sensor provided in the disaster prevention system in the area. In this case, the emergency situation can be quickly propagated.

In addition, the emergency signal may be transmitted to each terminal 100 by the administrator through the network 400 using the management server 500. In this case, if an emergency signal is received from a sensor or the like, the manager confirms the emergency situation through CCTV or the like. Then, if the emergency situation is met, the emergency signal generation means, such as an input means or a buzzer, And then transmitting the emergency signal to the base station. According to this method, it is possible to prevent an emergency situation from being propagated due to a malfunction of the sensor or playfulness. If an emergency signal is not transmitted by the manager even after a predetermined time has elapsed after the emergency signal is received, the management server 500 determines that the emergency signal has been received, and the management server 500 operates in such a manner that the emergency signal is automatically transmitted It is possible.

In addition, an emergency signal may be generated from the terminal 100. For example, when an abnormal sound signal such as a scream, gunshot, explosion sound, or the like, or a sensor for detecting an abnormal door opening / closing signal is directly connected to the terminal 100 and an abnormal signal is captured by the sensing means 600 The terminal 100 can operate in a manner that directly generates an emergency signal. Even in this case, the manager can send out the emergency signal after performing the above-described emergency situation checking procedure.

In addition, the emergency signal can send an emergency signal to all the user terminals 700 connectable to the terminal 100 or the network 400 by wire or wireless. To this end, it is possible for the user to install a dedicated application or the like capable of transmitting / receiving an emergency signal to the user terminal 700 in advance.

The emergency signal may be generated from the user terminal 700. [ For example, if an emergency situation is recognized by a user in the area earlier than the disaster prevention system or the administrator, the user can connect to the terminal 100 using the user terminal 700 or transmit the emergency signal via the network 400. Alternatively, the emergency telephone number or the emergency communication channel is informed to the user in advance, and when the user recognizes the emergency situation, an emergency signal is generated by accessing the emergency telephone number or the emergency communication channel through the user terminal 700 Alternatively, a separate emergency signal generating means such as a buzzer may be arranged in the vicinity of the moving path of each room or the user. Even in this case, the manager can send out the emergency signal after performing the above-described emergency situation checking procedure. The emergency situation propagation through the user terminal 700 can be effectively applied to emergency propagation and human evacuation when a local emergency situation occurs at a place where a large number of people such as a performance hall have gathered.

The emergency broadcast content may be displayed directly on the user terminal 700 in addition to being displayed on the display device 200. [ For example, when the user enters the region and the user terminal 700 held by the user comes within a range capable of transmitting and receiving signals or data with the network 400 or the terminal 100, When the user selects "Install ", the emergency-broadcast player is installed in the user terminal 700, and an emergency broadcast content is directly sent to the user terminal 700 in the event of an emergency So that it can be displayed as multimedia information. Alternatively, the emergency broadcast content may be displayed using a multimedia player previously installed in the user terminal 700, without installing a separate player.

The broadcasting method according to the present exemplary embodiment may transmit the emergency broadcasting in real time using the management server 500 or the user terminal 700 in addition to the emergency broadcasting contents stored in advance in the storage unit 30 of the terminal 100 . For example, an administrator can produce an emergency broadcast in real time using a multimedia broadcasting means such as a microphone, an IP camera, a broadcast encoder, a streaming server, and the like, provided in the management server 500, and provide it in the form of a data packet or a stream. In addition, the emergency situation captured by the CCTV or the like can be transmitted to the multimedia information through the multimedia broadcasting means. In addition, even in the case of a user, it is possible to input and output an emergency broadcast in real time using input means such as a camera and a microphone provided in the user terminal 700. [ According to this, it is possible to propagate the emergency occurrence situation which changes momentarily to the multimedia information in real time, and to lead to the safe evacuation of human life.

In addition, the emergency broadcasting transmitted in real time can be transmitted from the remote to the web by setting a multimedia service receiving address (URL) based on the IP. In this case, for example, when a risk of a thief, robbery, terrorism, or the like occurs in a specific area in the region, it is possible to send an emergency broadcast only to users located in the other area without inducing intruders to induce evacuation.

In addition, the broadcasting method according to the present example may include a control for operating one or more external devices together with or separately from the above-described emergency broadcasting. For example, an electronic door provided in a door, a window, an emergency exit, and the like may be connected to the terminal 100 of each room, and when the emergency signal is received, the terminal 100 may output a control signal for opening or closing the electronic door . In this case, the electronic door may be opened to induce evacuation of the user, or the electronic door may be closed to block entry or escape of the intruder. It is also possible to connect an external device such as a siren or an emergency lamp, and to output a control signal for operating the siren or the emergency lamp when an emergency occurs.

When the display device 20 is turned on, it is confirmed that the mode is the publicity guidance mode, and then the normal mode is switched to the publicity guidance mode.

In the publicity guidance mode, the control unit 10 executes a browser stored in the storage unit 30 to display the publicity guidance contents previously stored in the display unit 200. [ Accordingly, customized multimedia information prepared for the user of the room is transmitted.

The publicity information may be previously stored in the terminal 100 by the administrator using the input means provided in the management server 500, but is not limited thereto. That is, it is also possible to transmit the publicity announcement broadcast in real time using the multimedia broadcasting means provided in the management server 500 without storing it in advance. For example, a multimedia service receiving address (URL) is set from a remote web to a browser of the terminal 100 provided in the corresponding room through the management server 500, and an operation of the guest user to open and close the door of the guest room, The content stored in the management server 500 may be streamed through the stream server in conjunction with the operation of turning on the display device 200 using a remote controller.

In addition, the publicity announcement broadcasting may be performed in a bilateral or interactive manner in real time by a manager using a multimedia broadcasting means such as a microphone, an IP camera or the like provided in the management server 500. The guest can communicate with the manager by using input means such as a camera or a microphone, which is connected to the terminal 100 or provided to the display device 200. In this case, the browser may be implemented in the form of a chat window.

In the above description, the publicity information is displayed using a dedicated browser. However, the publicity information is not limited to such a form. For example, the publicity information may be used for the presentation of the publicity information, May be used.

According to the broadcasting method of the present embodiment, unlike the conventional broadcasting apparatus, it is possible to implement a publicity announcement broadcasting which can be customized and interacted with each other by moving away from the one-way and one-piece publicity means.

The broadcasting method according to the present disclosure may also be embodied in a form recorded in a computer-readable recording medium made of control logic or a program including instructions executable by a computer such as a program module executed by a computer. Computer readable media can be any available media that can be accessed by a computer, and can include both volatile and nonvolatile media, removable and non-removable media. The computer-readable recording medium may also include computer storage media. Computer storage media may include both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data.
