Method and apparatus for television sound signal regulation

Abstract

本发明的实施例公开了一种电视伴音信号调节的方法和装置,涉及数字信号处理领域,为解决由于每个频道的伴音响度不同而导致的电视播放不同频道节目时伴音变化较大的问题而发明。本发明实施例提供的方法包括:截取一时间片长度的当前频道的数字伴音信号作为采样值;根据所述采样值计算得到该当前频道的增益调整值;将所述增益调整值与用户设定的目标增益值相加,得到该当前频道的实际增益值;根据所述实际增益值对该当前频道的数字伴音信号进行增益控制。本发明实施例提供的方法和装置可以应用于数字电视机或机顶盒上。
The embodiment of the invention discloses a television sound signal conditioning method and device, pertaining to the field of digital signal processing, in order to solve the problem of larger accompanying sound variation when the television broadcasts different channel programs due to different accompanying sound loudness of each channel. The method provided by the embodiment of the invention includes: intercepting a time length of the digital sound signal of the current channel as a sampling value; calculating the gain adjustment value of the current channel according to the sampling value; adding the gain adjustment value to the object gain value set up by the user, to obtain the actual gain value of the current channel; performing gain control to the digital sound signal of the current channel according to the actual gain value. The method and device provided by the embodiment of the invention can be used on digital TV or set-top boxes.
