Abstract

본 발명은 레이저 디스크 플레어에서 레이저 디스크를 1/2배속, 1배속 및 2배속 재생할 경우에 음성신호를 뮤트시키지 않고 정상으로 출력하는 것으로서 종래에는 레이저 디스크를 배속재생할 경우에 배속도에 관계없이 음성신호를 뮤트시켜 출력되지 않도록 하였으므로 사용자가 음성신호를 청취하지 못하였다.According to the present invention, when a laser disc is reproduced at 1/2, 1, and 2 times in a laser disc flare, the audio signal is normally output without being muted. Since the mute was not outputted, the user could not hear the voice signal.

본 발명은 배속재생할 경우에 배속도를 판단하고, 1배속 또는 2배속 재생일 경우에 음성뮤트를 오프시켜 음성신호가 출력되게 하며, 1/2배속 재생일 경우에는 재생하는 프레임에 따라 음성뮤트의 온 및 오프를 제어하여 음성신호가 출력되게 함으로써 LD의 배속재생시에도 사용자가 음성신호를 청취할 수 있다.The present invention determines the double speed when playing at double speed, turns off the voice mute when playing at 1x or 2x speed, and outputs a voice signal when playing at 1 / 2x speed. By controlling the on and off to output the audio signal, the user can listen to the audio signal even during LD speed reproduction.

Claims

A first process of determining whether the laser disk is playing at a double speed, a second process of muting on the non-1x, 2x, or 1 / 2x playback in the first process so that a reproduced voice signal is not output; A third process of muting off at a 1x speed or a 2x speed playback in the first process to output a reproduced audio signal, and a mute on and muting according to a playback frame in the case of 1 / 2x playback in the first process And a fourth process of controlling the output of the reproduced audio signal.

The method of claim 1, wherein the fourth process mutes off when the first play of each frame is performed and mutes on when the play is not the first play.

The audio output method according to claim 1, wherein the fourth process mutes off when repeated playback of each frame and mutes on when not repeated playback.

The method of claim 1, wherein the fourth process determines whether it is the first playback of the 2N frame (where N is 0, 1, 2, ...) or the repeated playback of the 2N + 1th frame, and the first playback of the 2Nth frame. Or mute-off when not repeating playback of the 2N + 1th frame, and muting-on when not playing.

A first process for determining whether the laser disk is playing at a double speed, and if the play is not at 1, 2, or 1/2 speed in the first process, mute-on so that a reproduced audio signal is not output and 1x, 2x speed is muted. Or a second process of muting off and outputting a reproduced audio signal in the case of 1 / 2x playback.

※ Note: The disclosure is based on the initial application.
