영상기기 특히 티브이 수신기의 방송규격은 국가 및 지역에 따라 다르게 설 정될 수 있다.Broadcasting standards of video equipment, especially TV receivers, can be set differently depending on the country and region.

특히, 일부 국가에서는(예를 들어, 미국) 지진, 화재, 홍수 등 각종 재해에 대비하기 위하여 방송신호에 EAS(Emergency Alert System) 즉, 비상경보시스템 정보를 포함시켜 전송하도록 규격을 정하고 있다.In particular, in some countries (for example, the United States), in order to prepare for various disasters such as earthquakes, fires, and floods, standards are specified to include EAS (Emergency Alert System), or emergency alert system information, in a broadcast signal.

따라서 각 가정에 방송 서비스를 제공하는 유선 방송사는 방송신호에 EAS 정보를 포함시켜 전송한다.Accordingly, a wired broadcaster providing a broadcast service to each home includes EAS information in a broadcast signal and transmits it.

그리고 이를 수신한 가정의 티브이 수신기는 EAS 정보의 중요도에 따라 현재 시청중인 채널과 상관없이 EAS에 지정된 채널로 강제 변경하여 비상경보를 사용자가 시청할 수 있도록 한다.In addition, the TV receiver of the home receives the emergency alarm by forcibly changing to the channel specified in the EAS according to the importance of the EAS information so that the user can watch the emergency alarm.

물론, 현재는 상술한 비상경보시스템이 세계에서 공통적으로 시행되고 있는 것은 아니지만, 향후 국가 및 지역에 상관없이 필수사항이 될 것이다.Of course, the above-mentioned emergency alarm system is not commonly implemented in the world at present, but it will become a necessity regardless of country and region in the future.

또한 비상경보시스템의 적용은 방송규격상의 문제일 뿐, 기술적인 어려움은 없다.In addition, the application of the emergency alarm system is only a matter of broadcasting standards, there are no technical difficulties.

그러나, 상술한 종래의 영상기기는 다음과 같은 문제점이 있었다.However, the above-described conventional video device has the following problems.

첫째, 영상기기의 전원이 '오프'된 경우 EAS 정보에 따른 비상경보 관련동작을 수행할 수 없었다.First, when the power of the video device is 'off', emergency alarm related operation according to the EAS information could not be performed.

둘째, EAS 정보를 수신하여 채널절환 등을 수행하더라도 사용자가 시청중이 아니면 경보내용을 확인할 수 없었다.Second, even if the channel switching is performed by receiving the EAS information, the user cannot check the alarm contents unless the user is watching.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 영상기기의 파워가 꺼진 상태에서도 비상경보동작을 수행할 수 있도록 한 영상기기의 EAS 정보 처리장치 및 방법을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an apparatus and method for processing EAS information of an imaging device, which can perform an emergency alarm operation even when the imaging device is turned off.

본 발명의 다른 목적은 사용자가 영상기기를 시청하지 않더라도 비상경보발생을 알려 영상기기를 시청할 수 있도록 한 영상기기의 EAS 정보 처리장치 및 방법을 제공하는 것이다.Another object of the present invention is to provide an apparatus and method for processing EAS information of a video device, which enables the user to watch the video device by notifying an emergency alarm even when the user does not watch the video device.

상기 목적을 달성하기 위하여, 본 발명은 방송신호에서 EAS(Emergency Alert System) 정보를 검출하는 부가정보 검출부, 상기 검출된 EAS 정보에 따라 비상경보 동작 진행여부를 판단하고 비상경보 동작이 필요하면 기기 전원을 '온'시켜 상기 EAS 정보에 지정된 채널로의 절환 및 볼륨 증가가 이루어지도록 하는 제어부를 포함하는 영상기기의 EAS 정보 처리장치를 제공한다.In order to achieve the above object, the present invention provides an additional information detection unit for detecting EAS (Emergency Alert System) information in the broadcast signal, determine whether the emergency alarm operation proceeds according to the detected EAS information, if the emergency alarm operation is necessary It provides an EAS information processing apparatus of a video device including a control unit to 'on' to switch to the channel specified in the EAS information and to increase the volume.

상기 목적을 달성하기 위하여, 본 발명은 방송신호에서 EAS(Emergency Alert System) 정보를 검출하는 단계, 상기 EAS 정보에 따라 비상경보 동작 진행여부를 판단하는 단계, 그리고 상기 판단결과 비상경보 동작 진행이 필요하면 기기 전원을 '온'시키고 상기 EAS 정보에 지정된 채널로 절환하는 단계를 포함하는 영상기기의 EAS 정보 처리방법을 제공한다.In order to achieve the above object, the present invention requires the step of detecting Emergency Alert System (EAS) information from a broadcast signal, determining whether the emergency alert operation is in progress according to the EAS information, and the emergency alert operation is required. The method provides a method for processing EAS information of a video device, which includes turning on the device power and switching to a channel specified in the EAS information.

따라서 시청자가 비상경보 발생을 신속 정확하게 인식하여 적절한 대비를 할 수 있다.Therefore, viewers can quickly and accurately recognize the occurrence of emergency alarms and prepare appropriately.

이하 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.                     

도 1 및 도 2를 참조하여, 본 발명에 따른 영상기기의 EAS 정보 출력장치 및 방법의 실시예를 설명하면 다음과 같다.1 and 2, an embodiment of an EAS information output apparatus and method of an imaging apparatus according to the present invention will be described.

도 1에 도시된 바와 같이, 본 발명에 따른 영상기기의 EAS 정보 출력장치는 튜너(11), 영상처리부(13), 디스플레이부(15), 음성처리부(17), 스피커(19), 부가정보 검출부(21), 제어부(23), 메모리부(25) 및 전원부(27)를 포함한다.As shown in FIG. 1, an EAS information output apparatus of an imaging apparatus according to the present invention includes a tuner 11, an image processor 13, a display unit 15, an audio processor 17, a speaker 19, and additional information. The detection unit 21, the control unit 23, the memory unit 25, and the power supply unit 27 are included.

이때 도시되어 있지는 않지만, 각 구성들은 통신버스(예를 들어, I2C 버스)를 통해 각종 제어신호, 정보교환이 가능하도록 연결되어 있다.Although not shown at this time, each component is connected to enable various control signals, information exchange through a communication bus (for example, I2C bus).

이때 튜너(11)는 지정된 채널의 방송신호를 선국한다.At this time, the tuner 11 tunes a broadcast signal of a designated channel.

그리고 영상처리부(13)는 상기 튜너(11)를 통해 선국된 방송신호중 영상신호를 디스플레이부(15)를 통해 화면표시 가능하도록 처리한다.The image processor 13 processes the image signal among the broadcast signals tuned through the tuner 11 to be displayed on the display unit 15.

이어서 음성처리부(17)는 상기 튜너(11)를 통해 선국된 방송신호중 음성신호를 스피커(19)를 통해 출력가능하도록 처리한다.Subsequently, the voice processor 17 processes a voice signal of the broadcast signals tuned through the tuner 11 to be output through the speaker 19.

그리고 부가정보 검출부(21)는 상기 튜너(11)를 통해 선국된 방송신호에서 EAS 정보를 포함한 부가정보를 검출하여 제어부(23)로 출력한다.The additional information detector 21 detects additional information including EAS information from the broadcast signal tuned through the tuner 11 and outputs the additional information to the controller 23.

이어서 전원부(27)는 제어부(23)를 포함한 기기 각 구성들로 동작전원을 공급하며, 제어부(23)에 의한 전원공급 제어가 가능하도록 구성되어 있다.Subsequently, the power supply unit 27 supplies operating power to each component of the device including the control unit 23, and is configured to enable power supply control by the control unit 23.

그리고 메모리부(25)는 비상경보 동작을 위한 프로그램, 기기 기본동작관련 프로그램, 각종 설정값을 저장한다.The memory unit 25 stores a program for emergency alarm operation, a program related to the basic operation of the device, and various setting values.

이어서 제어부(23)는 상기 부가정보 검출부(21)에서 검출된 EAS 정보에 따라 비상경보 동작 진행여부를 판단한다. Subsequently, the controller 23 determines whether the emergency alarm operation is performed according to the EAS information detected by the additional information detector 21.                     

이때 EAS 정보는 우선순위, 비상경보 방송채널 정보 등을 포함하고 있다.At this time, the EAS information includes priority and emergency alarm broadcasting channel information.

따라서 우선순위가 정해진 수준이상인지 판단하여 비상경보 동작의 진행여부를 판단한다.Therefore, it is determined whether or not the emergency alarm operation is progressed by determining whether the priority is above a predetermined level.

또한 제어부(23)는 비상경보 동작 진행이 필요한 것으로 판단되면, 현재 기기의 전원이 '오프'되어 있는지 판단하고, 현재 '오프'되어 있으면 전원부(27)를 제어하여 기기 전원이 '온'되도록 한다.In addition, if it is determined that the emergency alarm operation is required, the controller 23 determines whether the power of the current device is 'off', and if the current power is 'off', the controller 23 controls the power supply unit 27 so that the device power is 'on'. .

또한 제어부(23)는 튜너(11)를 제어하여 EAS 정보에 지정된 비상경보 방송채널로 절환되도록 하고, 음성처리부(17)를 제어하여 볼륨이 설정된 레벨(예를 들어, 최고레벨)까지 증가되도록 한다.In addition, the controller 23 controls the tuner 11 to switch to the emergency alarm broadcasting channel specified in the EAS information, and controls the voice processing unit 17 so that the volume is increased to a set level (for example, the highest level). .

이때 볼륨 레벨을 증가시키는 것은 현재 시청자가 기기를 시청하지 않고 있는 경우 사용자를 호출하여 비상경보 방송을 시청할 수 있도록 하기 위한 것이므로 가능한 큰 소리가 출력되도록 하는 것이 바람직하다.In this case, since the increase in the volume level is for allowing the viewer to watch the emergency alarm broadcast by calling the user when the viewer is not currently watching the device, it is desirable to output the loudest sound as possible.

한편, 시청자가 기기에서 출력되는 소리를 듣고 비상경보 발생을 인지하여 정상적인 방송 시청을 위해 볼륨을 자신이 원하는 수준으로 낮추기 원할 경우, 현재 출력되고 있는 볼륨레벨에서 시청자가 원하는 수준까지 낮추기 위해서는 일정시간의 볼륨 감소키 입력이 필요하다.On the other hand, when the viewer listens to the sound output from the device and recognizes the occurrence of an emergency alarm and wants to lower the volume to the desired level for normal broadcast viewing, in order to lower the volume from the currently output volume level to the desired level of the viewer, Volume down key input is required.

따라서 메모리부(25)에 볼륨 레벨 증가 이전의 볼륨레벨을 저장할 수 있도록 하고, 시청자가 리모콘의 볼륨 키를 누르면 바로 볼륨레벨 증가 이전상태로 복원되도록 구성할 수 있다.Therefore, the memory unit 25 can store the volume level before the volume level increase, and when the viewer presses the volume key of the remote controller, the volume level can be restored to the state before the volume level increase.

도 2를 참조하여, 본 발명에 따른 영상기기의 EAS 정보 처리방법을 설명하면 다음과 같다.Referring to FIG. 2, an EAS information processing method of an image device according to the present invention will be described.

먼저, 부가정보 검출부(21)가 방송신호의 부가정보에서 EAS 정보를 검출하여 제어부(23)로 출력한다(S21).First, the additional information detector 21 detects the EAS information from the additional information of the broadcast signal and outputs the EAS information to the controller 23 (S21).

이어서 제어부(23)는 상기 EAS 정보에 포함된 우선순위를 판단한다(S23).Subsequently, the controller 23 determines the priority included in the EAS information (S23).

그리고 제어부(23)는 EAS 정보에 포함된 우선순위가 비상경보 동작 즉, EAS 에 지정된 채널로의 강제절환을 필요로 하는 수준인지 판단한다(S25).The controller 23 determines whether the priority included in the EAS information is a level requiring emergency switching operation, that is, forced switching to a channel designated in the EAS (S25).

이어서 제어부(23)는 EAS 정보에 포함된 우선순위가 비상경보 동작을 필요로 하는 수준으로 판단되면 현재 기기의 전원이 '온'상태인지 판단한다(S27).Subsequently, if it is determined that the priority included in the EAS information is a level requiring emergency alarm operation, the controller 23 determines whether the power of the current device is in an 'on' state (S27).

이때 기기의 전원상태는 세단계로 구분할 수 있다.At this time, the power state of the device can be divided into three stages.

즉, 기기의 전원이 '온'되어 영상 또는 음성출력이 정상적으로 이루어지고 있는 상태, 기기의 전원이 '오프'되어 영상 및 음성출력이 이루어지지는 않지만 사용자의 리모콘 신호를 대기하고 있는 상태, 그리고 전원 플러그 자체가 빠져 전원이 완전히 '오프'되어 리모콘 신호 대기가 불가능한 상태이다.That is, the power of the device is 'on' and the video or audio output is normally performed, the power of the device is 'off' and the video and audio output are not made, but the user is waiting for the remote control signal, and the power The plug itself has been pulled out and the power is completely 'off', preventing remote control signal waiting.

따라서 제어부(23)는 상기 판단결과(S27), 기기 전원이 '오프'상태이면 전원부(27)를 제어하여 정상적인 영상/음성 출력이 가능하도록 기기 전원을 '온'시킨다(S29).Therefore, the controller 23 controls the power supply unit 27 when the device power is 'off' to turn on the device power to enable normal video / audio output (S29).

그리고 제어부(23)는 튜너(11)를 제어하여 현재 채널(기기 전원 '오프'당시 채널)이 상기 EAS 정보에 지정된 채널 즉, 비상경보 방송채널로 절환되도록 한다(S31).The controller 23 controls the tuner 11 to switch the current channel (the channel at the time of device power 'off') to the channel specified in the EAS information, that is, the emergency alarm broadcasting channel (S31).

이어서 제어부(23)는 음성처리부(17)를 제어하여 볼륨 레벨을 일정시간 동안 증가시킨다(S33).Subsequently, the controller 23 controls the voice processor 17 to increase the volume level for a predetermined time (S33).

이때 시청자가 기기를 시청하고 있더라도 방송에 주의를 기울이지 않고 있을 수 있으므로 일정시간 동안 볼륨을 크게 하여 시청자의 주의집중을 돕는다.At this time, even though the viewer is watching the device, the user may not pay attention to the broadcast, thereby increasing the volume for a predetermined time to help the viewer to pay attention.

이때 볼륨 레벨은 사용자에게 비상경보를 알리기 위한 것이므로 가능한 크게 즉, 최고레벨로 하는 것이 바람직하다.At this time, since the volume level is for informing the user of the emergency alert, it is preferable to set the volume level as high as possible.

한편, 시청자가 기기를 시청하지 않고, 기기가 설치되어 있지 않은 장소(예를 들어, 다른 방)에 있을 수도 있다.On the other hand, the viewer may not be watching the device and may be in a place (for example, another room) where the device is not installed.

따라서 시청자가 소정 확인동작(예를 들어, 볼륨 조절키 입력)을 수행하기 전까지 볼륨 증가상태를 유지시킬 수도 있다.Therefore, the volume increase state may be maintained until the viewer performs a predetermined check operation (for example, input of a volume control key).

이때 제어부(23)는 사용자가 비상경보를 인식하고 확인동작 즉, 정상적인 기기 시청을 위해 볼륨 레벨을 낮추고자 볼륨 키를 입력하면, 음성처리부(17)를 제어하여 현재 볼륨레벨이 이전상태로 복원되도록 한다.At this time, the control unit 23 recognizes the emergency alarm and enters the volume key to confirm the confirmation, that is, to lower the volume level for normal device viewing, and controls the voice processing unit 17 so that the current volume level is restored to the previous state. do.

예를 들어, 볼륨을 15로 하여 기기 시청중인 상태에서, 비상경보 동작에 따라 볼륨을 60으로 증가시켰다고 가정하자.For example, suppose that while the device is being viewed at a volume of 15, the volume is increased to 60 according to the emergency alarm operation.

이때 시청자가 비상경보를 인식하고 정상적인 경보방송 시청을 위해서는 상기 60이란 볼륨은 너무 크므로 볼륨을 15 비슷한 수준으로 낮추기를 원할 것이다.At this time, the viewer may want to lower the volume to a level similar to 15 because the volume 60 is too large to recognize the emergency alert and watch the normal alarm broadcast.

그러나 볼륨을 60에서 15로 낮추기 위해서는 리모콘의 볼륨 감소키를 비교적 장시간 누르고 있어야 하므로 시청자는 불편하다 느낄 수 있다.However, to lower the volume from 60 to 15, the viewer may feel uncomfortable because the user must press and hold the volume down key of the remote controller for a relatively long time.

따라서 상술한 비상경보 동작에 따라 볼륨이 최고레벨로 증가된 상태에서 사용자가 볼륨 키를 누르면 비상경보를 사용자가 인식한 것으로 판단하여 이전 볼륨 으로 자동 복원되도록 하는 것이다.Therefore, when the user presses the volume key in the state in which the volume is increased to the highest level according to the above-described emergency alarm operation, it is determined that the emergency alarm is recognized by the user and automatically restored to the previous volume.

본 발명은 상술한 실시예에 한정되지 않으며, 첨부된 청구범위에서 알 수 있는 바와 같이 본 발명이 속한 분야의 통상의 지식을 가진 자에 의해 변형이 가능하고 이러한 변형은 본 발명의 범위에 속한다.The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

상기에서 설명한 본 발명에 따른 영상기기의 EAS 정보 처리장치 및 방법의 효과를 설명하면 다음과 같다.The effects of the EAS information processing apparatus and method of the imaging apparatus according to the present invention described above are as follows.

본 발명은 기기 전원이 '오프'되어 있어도 자동으로 전원을 '온'시켜 비상경보 방송이 출력되도록 하고, 비상경보 방송 출력과 동시에 볼륨을 크게 하므로, 시청자가 비상경보 발생을 신속 정확하게 인식하여 적절한 대비를 할 수 있다.The present invention automatically turns on the power even when the device is 'off', so that the emergency alarm broadcast is output, and the volume is increased at the same time as the emergency alarm broadcast output, so that the viewer can recognize the emergency alarm occurrence quickly and accurately and prepare appropriately. You can do
