Abstract

본 발명은 포터블 CDP에 영상 및 자막을 재생할 수 있는 기능을 추가하여 CDP 상면에 장착된 TFT LCD를 통하여 영상 및 노래자막을 디스플레이할 수 있도록 한 것으로, 종래의 노래반주 장치는 노래반주 자막 및 영상을 재생할 수 있는 기능이 없으며, 사용자가 포터블 CDP를 통해 CD에 기록된 오디오 신호를 재생할 때 단순히 오디오 신호만이 출력되므로서 사용자의 다양한 욕구를 충족시키지 못하는 문제점이 있었다, 본 발명은 종래의 이와같은 문제점을 해결하기 위하여 영상 오디오 처리부(B)와 자막처리부(C)를 두어 중앙제어부(22)의 제어를 받아 선택부(32)에서 CD데크부(A)에 재생되어지는 CD(23)를 인식하여 오디오 신호를 분배하므로서 영상 CD 및 노래반주 CD를 재생할 수 있고 또한 포터블 CDP 상면에 TFT LCD(47)를 장착하여 노래반주의 자막 및 영상을 디스플레이 할 수 있으므로 사용자는 TFT LCD(47)에서 디스플레이된 영상 및 자막을 보면서 노래를 부를 수 있는 것이다.The present invention adds a function of playing video and subtitles to a portable CDP so that video and song subtitles can be displayed through a TFT LCD mounted on the top of the CDP. There is no playable function, and when the user plays the audio signal recorded on the CD through the portable CDP, only the audio signal is output and there is a problem that does not satisfy various needs of the user. In order to solve the problem, the video audio processing unit B and the subtitle processing unit C are placed under the control of the central control unit 22, and the selection unit 32 recognizes the CD 23 to be played on the CD deck unit A. By distributing audio signals, video CDs and song accompaniment CDs can be played back, and a TFT LCD 47 is mounted on the top of the portable CDP to display subtitles and images of song accompaniments. The user can sing while watching the video and subtitle displayed on the TFT LCD 47.
