Abstract

本发明涉及一种自动静音的显示器。在显示器的OSD功能的audio mute功能选项中,增加Auto选项,以实现显示器能够依据讯号源的mute flag来控制显示器的声音是否静音。本发明解决了显示器出现杂音、播放音乐却无声的问题。

Description

自动静音的显示器
技术领域
本发明涉及自动静音的显示器。
背景技术
一般来说HDMI InfoFrame中有AVMUTE flag或DP的VB-ID中有AudioMute_Flag,表示来源端要静音。
而Audio mute的选项,只有enable与disable两种。
如此若
1、来源端没有送出声音讯号时,显示器若没有静音,且喇叭音量或功率较大时,会听到低音量的杂音。
2、来源端的mute flag与声音资料不一致,导致播放音乐却无声。
发明内容
本发明的目的在于提供一种克服上述问题的自动静音的显示器,该显示器解决了显示器出现杂音、播放音乐却无声的问题。
为实现上述目的,本发明的技术方案是:一种自动静音的显示器,在显示器的OSD功能的audio mute功能选项中,增加Auto选项,以实现显示器能够依据讯号源的mute flag来控制显示器的声音是否静音。
在本发明一实施例中,audio mute功能选项中的Auto选项具体实现功能如下,
(a)若讯号源为HDMI,则依 InfoFrame的 AVMUTE flag,来决定是否要静音;
(b)若讯号源为DP,则依VB-ID中的AudioMute_Flag,来决定是否要静音;
(c)当讯号穏定后,仍然要时续侦测上述的mute flag,来决定是否要静音。
相较于现有技术,本发明具有以下有益效果:本发明解决了显示器出现杂音、播放音乐却无声的问题。
附图说明
图1为本发明显示器自动静音功能实现流程图。
具体实施方式
下面结合附图,对本发明的技术方案进行具体说明。
如图1所示,本发明的一种自动静音的显示器,在显示器的OSD 功能的audio mute功能选项中,增加Auto选项,以实现显示器能够依据讯号源的mute flag来控制显示器的声音是否静音。
在本发明一实施例中,audio mute功能选项中的Auto选项具体实现功能如下,
(a)若讯号源为HDMI,则依 InfoFrame的 AVMUTE flag,来决定是否要静音;
(b)若讯号源为DP,则依VB-ID中的AudioMute_Flag,来决定是否要静音;
(c)当讯号穏定后,仍然要时续侦测上述的mute flag,来决定是否要静音。
以下为本发明的具体实现过程。
1、在OSD audio mute的功能选项,增加 “Auto” 选项。
2、当选到Auto时,会依讯号源的mute flag来控制声音是否静音。
(a) 若讯号源为HDMI,则依 InfoFrame的 AVMUTE flag,来决定是否要静音。
(b) 若讯号源为DP,则依VB-ID中的AudioMute_Flag,来决定是否要静音。
(c) 当讯号穏定后,仍然要时续侦测上述的mute flag,来决定是否要静音。
3、当选到 Enable时,不论讯号源是否有指示要静音,都以静音处理。
4、当选到 Disable时,不论讯号源是否有指示要静音,都以声音开启处理。
以上是本发明的较佳实施例,凡依本发明技术方案所作的改变,所产生的功能作用未超出本发明技术方案的范围时,均属于本发明的保护范围。

Claims (2)

1.一种自动静音的显示器,其特征在于:在显示器的OSD 功能的audio mute功能选项中,增加Auto选项,以实现显示器能够依据讯号源的mute flag来控制显示器的声音是否静音。
2.根据权利要求1所述的自动静音的显示器,其特征在于:audio mute功能选项中的Auto选项具体实现功能如下,
(a)若讯号源为HDMI,则依 InfoFrame的 AVMUTE flag,来决定是否要静音;
(b)若讯号源为DP,则依VB-ID中的AudioMute_Flag,来决定是否要静音;
(c)当讯号穏定后,仍然要时续侦测上述的mute flag,来决定是否要静音。
