Abstract

The invention relates to an audio mute soft release device and method, for example, on the condition of releasing audio mute because of terminating trick play, DVD player and various CD devices will gradually and variably regulate audio volume according to the audio level to be outputted, to softly output audio output level in fade-in state, so as to be unable to instantly output higher-level audio when releasing the audio mute, thus able to make a user more naturally listen in to audio.

Description

【Technical field】 [0001] The invention relates to an audio mute soft release device and a method thereof. This refers to the gradual adjustment of the audio volume according to the audio level to be output when the audio mute (Audio Mute) is released due to suspension of trick play (Trick Play) etc. in various types of optical disc devices such as DVD players. (Audio Volume), so that the audio output level is cut into (Fade-In) state and carries out soft output audio mute soft release device and method thereof. 【Background technique】 [0002] Currently, optical disc devices such as DVD players that can read high-quality video data and high-quality audio data for a long time are widely used. Such as figure 1 As shown, the DVD player includes: an optical disc 10 , an optical pickup 11 , a Video Disc Play (VDP for short) system 12 , a microcomputer 13 , an on-screen display (OSD) generator 14 , and a memory 15 . [0003] Simultaneously, above-mentioned microcomputer 13 inser...
