상기한 바와 같은 목적을 달성하기 위한 본 발명에 따른 가상현실 시스템을 크게 두 부분으로 구분하면, 영상매체(100)로부터 비디오 및 오디오신호를 입력받아 구동부가 작동하도록 명령을 내리는 가상현실 구동신호를 발생시키는 가상현실신호발생부(A)와, 그 발생된 가상현실 구동신호를 수신해서 그 수신된 신호에 따라 가상현실장치가 작동되도록 제어하는 가상현실구동부(B)로 구성된다.When the virtual reality system according to the present invention for achieving the above object is largely divided into two parts, a virtual reality driving signal is generated which receives a video and audio signal from the image medium 100 and commands the driving unit to operate. It consists of a virtual reality signal generation unit (A), and a virtual reality driving unit (B) for receiving the generated virtual reality drive signal and controlling the virtual reality device to operate according to the received signal.

이하 첨부된 도면들에 의거하여 본 발명에 따른 가상현실 시스템에 대한 구성과 작용을 상세히 서술한다.Hereinafter, the configuration and operation of the virtual reality system according to the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명의 실시예로서, 텔레비전(100)에 가상현실 시스템을 적용한 것을 보이고 있다. 텔레비전과 유선으로 연결된 가상현실신호발생부(A)는 그 텔레비전의 비디오신호와 오디오신호를 입력받아 가상현실 구동신호를 출력하며, 가상현실구동부(B)는 그 출력된 구동신호를 수신해서 그 신호에 따라 회전, 진동, 충격의 작동명령을 해서 가상현실장치; 예컨데 의자를 작동시킨다.1 shows an embodiment of the present invention in which a virtual reality system is applied to a television 100. The virtual reality signal generator A connected to the television by wire receives the video signal and the audio signal of the television and outputs the virtual reality drive signal. The virtual reality driver B receives the output drive signal and outputs the signal. According to the operation command of the rotation, vibration, shock virtual reality device; For example, activate the chair.

도2는 레코딩(recording) 작업의 흐름도을 보여주는 블록도로서, 영상매체의 비디오신호 (110)와 오디오신호(120)와 상기 두 신호에서 제어가 필요한 부분의 신호를 추출한 가상현실제어신호(130)를 입력받아 신호합성부(200)에서 합성을 한 다음, 그 합성된 신호를 기억할 수 있는 녹화, 녹음 테이프와 같은 기록매체를 가진 기록장치(300)에 저장을 한다.FIG. 2 is a block diagram showing a flowchart of a recording operation. The video signal 110 and the audio signal 120 of the video medium and the virtual reality control signal 130 from which the signals of the portions to be controlled are extracted from the two signals are shown. After the input is synthesized by the signal synthesizing unit 200, the synthesized signal is stored in a recording device 300 having a recording medium such as a recording or a recording tape capable of storing the synthesized signal.

그 다음 단계로는 도3에서와 같이 기록장치(300)에 기록 저장된 합성 신호를 입력받아 신호분리부(400)에서 다시 비디오 신호와 오디오 신호와 가상현실신호를 분리시켜 각각 비디오 제어부(110a)와 오디오 제어부(120a)와 가상현실제어부(500)로 보내준다. 여기서 가상현실제어부(500)는 신호분리부(400)로부터 분리된 가상현실신호를 입력받아 가상현실장치(600)를 구동시키도록 명령하는 가상현실 구동신호를 출력해 가상현실장치에 전달한다. 그 가상현실 구동신호에 따라 가상현실장치 (600)는 회전, 충격, 진동의 작동을 하게 된다.In the next step, as shown in FIG. 3, the composite signal recorded and stored in the recording apparatus 300 is input, and the video separation unit 400 separates the video signal, the audio signal, and the virtual reality signal, respectively, and the video control unit 110a and The audio control unit 120a and the virtual reality control unit 500 are sent. Here, the virtual reality controller 500 receives the virtual reality signal separated from the signal separator 400 and outputs a virtual reality driving signal for instructing the virtual reality device 600 to be driven and transmitted to the virtual reality device. In response to the virtual reality driving signal, the virtual reality device 600 is operated to rotate, shock, and vibrate.

한편 비디오신호와 오디오신호와 가상현실신호를 합성시키는 신호합성부가 없는 일반 비디오 테이프와 녹음 테이프등의 기록장치(300')에 본 발명에 따른 가상현실 시스템을 적용할 때에는 도4와 같은 과정으로 진행이 이루어진다.On the other hand, when the virtual reality system according to the present invention is applied to a recording device 300 'such as a general video tape and a recording tape without a signal synthesis unit for synthesizing a video signal, an audio signal and a virtual reality signal, the process proceeds to the process shown in FIG. This is done.

도4의 기록장치(300')는 신호합성부(200)가 없기 때문에 기록장치의 비디오신호와 오디오신호를 신호분리부(400)에서 각각 분리해서 비디오신호는 비디오제어부(110a)로, 오디오신호는 오디오제어부(120a)로 보내준다. 상기 오디오제어부는 분리된 오디오신호를 음성인식부(700)에 전달하며, 음성인식부에서는 전달받은 오디오신호로부터 가상현실 제어가 필요한 부분의 신호만을 가상현실신호로 추출하게 된다. 이렇게 추출된 가상현실신호는 가상현실제어부(500)에서 가상현실 구동신호로 출력되어 가상현실장치(600)를 구동시킨다.Since the recording device 300 'of FIG. 4 has no signal synthesizing unit 200, the video signal and the audio signal of the recording device are separated from the signal separating unit 400, and the video signal is transferred to the video control unit 110a. Sends to the audio controller 120a. The audio controller transmits the separated audio signal to the voice recognition unit 700, and the voice recognition unit extracts only the signal of the part requiring virtual reality control from the received audio signal as the virtual reality signal. The extracted virtual reality signal is output from the virtual reality controller 500 as a virtual reality driving signal to drive the virtual reality device 600.

그리고 도5에서 보이는 바와 같이 가상현실제어부의 구성요소인 가상현실장치 조작부(510)는 신호분리부에서 분리된 가상현실신호를 입력으로 해서 소정의 가상현실 구동신호 출력시켜 가상현실신호 처리부(520)로 전달하고, 가상현실신호 처리부는 그 전달받은 가상현실 구동신호 또는 소정의 가상현실신호를 판별해서 회전신호이면 회전장치구동부(530)로, 진동신호이면 진동장치구동부(540)로, 충격신호이면 충격장치구동부(550)로 구동신호를 전달하며, 각각의 가상현실장치의 구동부 는 전달받은 구동신호에 따라 각각의 회전, 진동, 충격장치(610,620,630)를 작동시키게 된다.As shown in FIG. 5, the virtual reality device operator 510, which is a component of the virtual reality controller, receives a virtual reality signal separated from the signal separator as an input and outputs a predetermined virtual reality driving signal to the virtual reality signal processor 520. And the virtual reality signal processor detects the received virtual reality drive signal or a predetermined virtual reality signal, and if the rotation signal is a rotation device, the rotation device driver 530, if the vibration signal, the vibration device driver 540, and the impact signal. The driving device transmits a driving signal to the impact device driver 550, and the driving unit of each virtual reality device operates each of the rotation, vibration, and impact devices 610, 620, and 630 according to the received driving signal.

도6은 가상현실신호 처리부(520)의 플로우 차트를 보여주고 있으며, 가상현실장치 조작부(510)에서 보낸 가상현실신호(S130)가 입력이 되면 첫 번째로 회전신호인가를, 두 번째로는 진동신호인가를, 세 번째로는 충격신호인가를 각각의 논리판단부(S521,S522,S523)에서 판단해서 각각의 회전, 진동, 충격장치등의 가상현실장치(600)를 구동시킨다.FIG. 6 shows a flow chart of the virtual reality signal processor 520. When the virtual reality signal S130 sent from the virtual reality control unit 510 is input, the rotation signal is first applied and the second is vibration. The application of the signal, and the third application of the impact signal, is judged by the logic determination units S521, S522, and S523 to drive the virtual reality devices 600 such as rotation, vibration, and impact devices.

이상에서 본 바와 같이 본 발명에 따른 가상현실 시스템은 영상물의 영상과 음성을 종합적으로 인식하여 의자등의 가상현실장치에 그 영상 및 음성의 상황에 따라 입체적인 회전, 진동, 충격등을 줌으로써, 시청자나 청취자들 자신이 영상물의 일부인 것처럼 느낄 수 있도록 하는 효과가 있다.As described above, the virtual reality system according to the present invention comprehensively recognizes the image and sound of an image and gives a three-dimensional rotation, vibration, shock, etc. to a virtual reality device such as a chair according to the situation of the image and sound. There is an effect that allows the listener to feel as if they are part of the video.
