Abstract

본 발명은 재생절환보드의 설정에 따라 비디오디스크에 대한 EFM복조가 가능하도록 절환기능이 수행되도록 하는 DVD재생시스템에서의 EFM/EFM Plus복조 절환장치를 제공한다.The present invention provides an EFM / EFM Plus demodulation switching device in a DVD playback system in which a switching function is performed to enable EFM demodulation of a video disc according to a setting of a playback switching board.

그에 따라 본 발명은 디지탈비디오디스크로부터의 동영상/음성정보를 독출하여 재생하도록 된 DVD재생시스템에 있어서; 비디오디스크의 호환적인 EFM 복조를 위한 재생절환모드를 키설정하는 기능설정수단(30)과, 상기 기능설정수단(30)에 의한 재생절환모드의 설정에 따라 비디오디스크의 EFM복조를 위한 스위칭제어신호를 발생하는 제어수단(32) 및, 상기 제어수단(32)으로부터의 스위칭제어신호의 의해 스위칭절환되어 EFM Plus복조기(38)와 EFM 복조기(40)측에 선택적으로 디스크로부터의 신호데이터가 공급되도록 하는 스위칭절환부(42)를 갖춘 디지털신호처리수단(34)을 구비하여 구성된 것을 특징으로 한다.Accordingly, the present invention provides a DVD playback system configured to read out and play back video / audio information from a digital video disk; A function setting means 30 for key setting a playback switching mode for compatible EFM demodulation of the video disk, and a switching control signal for EFM demodulation of the video disk according to the setting of the playback switching mode by the function setting means 30; Switching means are switched by the control means 32 and the switching control signal from the control means 32 so that the signal data from the disk is selectively supplied to the EFM Plus demodulator 38 and the EFM demodulator 40 side. It is characterized by comprising a digital signal processing means 34 having a switching switching unit 42 to.
