본 발명은 재생유니트가 이동하면서 오디오음을 재생하는 오디오장치에 관한 것으로서, 더욱 상세하게는 재생중에 전원을 오프한 후 다시 전원온시에 랜덤(Random)하게 곡이 재생되도록 하는 오디오재생장치의 재생위치결정방법에 관한 것이다.The present invention relates to an audio device for reproducing an audio sound while a playback unit is moved. More particularly, the present invention relates to an audio device for reproducing an audio randomly when a power is turned off and then on again. It relates to a positioning method.
제1도는 일반적인 오디오재생장치중 컴팩트 디스크 재생장치의 블록 구성도를 도시한 것으로, 기록매체인 디스크(1)를 일정한 속도로 회전시켜주는 디스크 회전모터(M1)와, 디스크(1)로부터 기록된 신호를 추종하고 신호를 읽어낼 수 있는 재생유니트인 픽업(2)과, 디스크 회전모터(M1)의 회전을 일정하게 제어하고 픽업(2)이 신호를 추종할 수 있도록 제어하는 서보 제어부(3)와, 상기 픽업(2)에 의해 디스크(1)로부터 읽어들인 신호를 분석정정하여 신호분리하는 신호처리부(4)와, 각종 키입력을 위한 키부(5)와, 시스템 동작상태를 표시하는 표시부(6)와, 상기 표시부(6)를 제어하며 전체 시스템을 제어하고 데이타를 저장할 수 있는 불휘발성 메모리를 구비하는 시스템 제어부(7)와, 상기 신호처리부(4)로부터의 신호를 아날로그신호로 변환하여 좌우(L,R)채널 오디오신호를 출력하는 D/A변환부(8)로 구성된다.FIG. 1 is a block diagram of a compact disc reproducing apparatus of a general audio reproducing apparatus. The disc rotating motor M1 which rotates the disc 1 which is a recording medium at a constant speed, Pick-up 2, which is a reproducing unit capable of following signals and reading signals, and a servo control unit 3 which controls the rotation of the disc rotating motor M1 to be constant and controls the pickup 2 to follow signals. And a signal processing section 4 for analyzing and correcting the signals read out from the disk 1 by the pickup 2, separating the signals, a key section 5 for various key inputs, and a display section for displaying the system operation state ( 6), a system control unit 7 having a nonvolatile memory capable of controlling the display unit 6 and controlling the entire system and storing data, and converting signals from the signal processing unit 4 into analog signals. Left and right (L, R) channel And a D / A converter 8 for outputting a video signal.
상기와 같은 구성을 갖는 종래의 컴팩트 디스크 재생장치에서 전원이 인가되면 서보 및 시스템 제어부(3),(7)의 제어에 따라 디스크 회전모터(M1)가 동작하여 디스크(1)에 수록된 곡이 재생되게 된다.When power is applied in the conventional compact disc reproducing apparatus having the above-described configuration, the disc rotating motor M1 operates under the control of the servo and the system controllers 3 and 7 to reproduce the music recorded on the disc 1. Will be.
이때, 상기 시스템 제어부(7)의 재생되는 곡의 번호와 픽업(2)의 위치를 감지하여 시스템 제어부(7) 내부의 메모리에 저장하게 되며, 신호처리부(4)는 픽업(2)에 의해 재생되는 음을 처리하여 D/A변환부(8)을 통하여 오디오음을 출력하게 된다.At this time, the number of the song to be reproduced by the system control unit 7 and the position of the pickup 2 is sensed and stored in the memory inside the system control unit 7, and the signal processing unit 4 is reproduced by the pickup (2) The sound is processed and the D / A converter 8 outputs the audio sound.
한편, 재생중에 사용자가 전원을 오프시키면 상기 시스템 제어부(7)는 이를 감지하여 메모리에 재생이 중지된 시점의 픽업(2)의 위치 및 곡번호를 저장하였다가 사용자가 다시 음악을 듣고자 전원을 온시키면 재생이 중지된 곡의 위치에서부터 재생을 시작하게 되거나 그 디스크에 수록된 곡의 제일 처음곡부터 다시 재생을 하게 된다.On the other hand, if the user turns off the power during playback, the system control unit 7 detects this and stores the position and song number of the pickup 2 at the time when playback is stopped in the memory, and then turns on the power to listen to music again. When it is turned on, playback starts from the position of the song stopped from playing, or from the beginning of the first song on the disc.
즉, 전원이 오프되면 시스템 제어부(7)가 전원오프시점의 곡번호 및 픽업(2)의 위치를 시스템 제어부(7) 내부의 메모리에 저장하고 있다가 다시 전원이 온되었을 때 재생이 중지된 곡의 위치부터 음악이 재생되게 되거나 그 디스크의 제일 처음 곡부터 재생이 되게 된다.That is, when the power is turned off, the system control unit 7 stores the song number at the time of power off and the position of the pickup 2 in the memory inside the system control unit 7, and then the playback stops when the power is turned on again. The music is played from the position of or the first track of the disc is played.
따라서 전원 오프후 다시 전원을 온하면 전원오프시 재생이 중단된 곡의 위치부터 재생이 되거나 그 디스크에 수록된 처음곡부터 재생이 되므로 곡의 중간부터 듣게되는 불편함이나 자동차에서 처럼 짧은 시간을 자주 청취하는 청취자의 경우 항상 동일한 곡을 자주 감상하게 되고 디스크의 후반에 수록된 곡을 청취하려면 별도의 키조작을 행하여야만 하는 불편함이 따랐다.Therefore, if you turn on the power again after the power is turned off, it will be played from the position of the song that was stopped when the power was turned off or from the first song recorded on the disc. In the case of a listener who listens to the same song frequently, it is inconvenient to perform a separate key operation in order to listen to the song recorded in the second half of the disc.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 오디오 재생장치에서 전원오프후 다시 전원온시 그 디스크에 수록된 곡이 랜덤하게 재생되도록 한 오디오재생장치의 재생위치결정방법을 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a playback positioning method of an audio playback apparatus such that the songs recorded on the disk are randomly played when the power is turned off and then on again. .
이러한 목적을 달성하기 위한 본 발명의 특징은 재생유니트가 이동하여 기록매체에 기록된 정보를 재생하는 오디오재생장치의 재생위치결정방법에 있어서, 상기 기록매체에 기록된 곡의 재생중 전원이 오프되었다가 전원이 다시 온되면 전원오프시의 재생유니트의 위치를 확인하는 제1단계와, 상기 재생유니트를 랜덤 재생프로그램에 의해 선택된 곡의 선두위치로 이동시켜 정상재생을 수행하는 제2단계로 이루어지는 오디오재생장치의 재생위치결정방법에 있다.A feature of the present invention for achieving this object is a reproducing positioning method of an audio reproducing apparatus in which a reproducing unit is moved to reproduce information recorded on a recording medium, wherein power is turned off during reproduction of a song recorded on the recording medium. When the power is turned on again, the audio includes a first step of checking the position of the playback unit at the time of power-off and a second step of moving the playback unit to the head position of the song selected by the random playback program and performing normal playback. A playback positioning method of a playback device.
이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조로 하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.
우선, 본 발명은 제1도와 같은 시스템에서 수행되게 되며 이러한 시스템에서 수행되는 본 발명을 제2도의 플로우 챠트와 함께 설명한다.First, the present invention will be performed in a system such as that of FIG. 1 and the invention performed in such a system will be described with the flowchart of FIG.
먼저, 재생중에 전원이 오프되면 시스템 제어부(7)는 내부의 메모리에 디스크의 정보(TOC : Table of Contents)를 유지하게 되며, 픽업(2)의 위치를 감지하여 저장하게 된다.First, when the power is turned off during playback, the system control unit 7 maintains the disk information (TOC: Table of Contents) in the internal memory, and detects and stores the position of the pickup 2.
이 상태에서 전원이 다시 온되면 디스크(1)가 도시하지 않은 데크에 안착되어 있는가를 판단하여 디스크(1)가 없으면 튜너모드나 테이프 등의 모드가 되며, 디스크(1)가 있으면 CD모드가 된다(S10),(S20).In this state, when the power is turned on again, it is judged whether the disk 1 is seated on a deck (not shown). If the disk 1 is not present, it is in a tuner mode or a tape mode. S10), (S20).
CD모드가 되면 디스크(1)에 수록된 TOC정보가 전원오프시 시스템 제어부(7)의 메모리에 저장되었으므로 상기 시스템 제어부(7)는 현재 안착되어 있는 디스크(1)의 곡 정보를 알게 되므로 상기 시스템 제어부(7)는 랜덤 재생 프로그램에 의해 현재 안착되어 있는 디스크(1)의 전체 곡중 무작위로 선택하여 선택된 곡의 처음위치로 픽업(2)을 이송시켜 선택된 곡의 처음부터 정상재생하게 된다(S30),(S40).In the CD mode, since the TOC information recorded on the disk 1 is stored in the memory of the system controller 7 when the power is turned off, the system controller 7 knows the song information of the disk 1 currently seated. (7) randomly selects all the songs of the disc 1 currently seated by the random reproducing program and transfers the pickup 2 to the start position of the selected song to play normally from the beginning of the selected song (S30). (S40).
이때, 상기 시스템 제어부(7)의 랜덤 재생 프로그램은 전원오프시 픽업(2)의 위치정보와 함께 곡정보가 시스템 제어부(7)의 메모리에 저장되도록 하면 전원오프시에 재생되던 곡은 선택되지 않도록 할 수도 있다. 한편, 본 발명은 기록매체가 고정되고 재생유니트가 이송가능한 장치(예 : 미니디스크 플레이어)에 적용가능하다. 이상에서 살펴본 바와 같이 본 발명은 사용자가 음악을 청취하던중 오디오기기의 작동을 멈추었다가 다시 오디오기기를 작동시키면 현재 악착되어 있는 디스크에 수록된 곡중 하나가 무작위로 선택되어 선택된 곡의 처음부터 재생되도록 함으로써 사용자의 부수적인 키조작없이 디스크에 수록된 곡중 어느 하나의 곡을 처음부터 감상할 수 있게 되는 효과가 있다.At this time, the random playback program of the system controller 7 causes the song information to be stored in the memory of the system controller 7 together with the position information of the pickup 2 when the power is turned off so that the song played when the power is turned off is not selected. You may. On the other hand, the present invention is applicable to an apparatus (e.g., mini-disc player) in which the recording medium is fixed and the playback unit is transportable. As described above, when the user stops the operation of the audio device while listening to music and then operates the audio device again, one of the songs on the currently stuck disk is randomly selected to play from the beginning of the selected song. There is an effect of being able to listen to any one of the songs contained on the disc from the beginning without the user's additional key operation.
