本实施例中,节目源可以为音视频节目,也可以为纯音频节目及其他包含有音频数据的多媒体节目,在此不作限定。接收到节目源后,对节目源的音频数据进行解码,获取脉冲编码调制(Pulse Code Modulation,简称PCM)数据。
步骤S20,对预设时间内的脉冲编码调制数据进行统计分析,获取音频特征值;
对解码出的脉冲编码调制数据进行处理,对预设时间内即一定时间窗口内的脉冲编码调制数据进行统计分析,获取能体现节目源音频数据的音频特性的音频特征值。能反映一定时间窗口内的脉冲编码调制数据的音频特征值可以包括最大幅值、最小幅值、平均音频幅值等参数,也可以利用多种参数进行数学运算及组合来更加精准的获取该音频特征值,本实施例中,所述音频特征值优选为脉冲编码调制数据在预设时间内的平均音频幅值,以避免预设时间内因干扰突发的较大幅值、较小幅值的影响,能体现节目源音频数据的整体音频特性,当然,也不限定所述音频特征值为其他参数值。
步骤S30,将所述音频特征值与预先设定的音频幅值参考值进行比较,并根据比较结果对所述脉冲编码调制数据进行处理,以调节输出的音量大小。
本实施例中,用户可以根据自身需求预先设定一常用的音频幅值参考值,在音频处于该常用的音频幅值参考值时,输出的音量大小为最佳。将所述音频特征值即脉冲编码调制数据在预设时间内的平均音频幅值与预先设定的音频幅值参考值进行比较,若所述平均音频幅值大于预先设定的音频幅值参考值,则对所述脉冲编码调制数据进行衰减,直至所述平均音频幅值与预先设定的音频幅值参考值相等;若所述平均音频幅值小于预先设定的音频幅值参考值,则对所述脉冲编码调制数据进行增强,直至所述平均音频幅值与预先 设定的音频幅值参考值相等。这样,使得输出的脉冲编码调制数据的平均音频幅值均与预先设定的音频幅值参考值相等,无论不同节目源的原始音量是否相同,都能保证最后输出的音量大小为最佳,不会出现输出音量忽高忽低的情况。
进一步地,在另一种实施方式中,用户还可根据实际情况预先设定一常用的音频幅值参考值及门限值,在音频处于该常用的音频幅值参考值的上下门限值范围内时,输出的音量大小既不会过大,也不会过小,可以使用户舒适的观看节目。而且将输出的音量大小限制在一个较小的波动范围内,实际操作更加简易、快速。
将能体现节目源音频数据的音频特性的音频特征值即脉冲编码调制数据在预设时间内的平均音频幅值与预先设定的音频幅值参考值进行比较,若所述平均音频幅值大于预先设定的音频幅值参考值,且所述平均音频幅值与所述音频幅值参考值之差的绝对值大于设定的门限值,则说明所述平均音频幅值偏离所述音频幅值参考值的范围过大,对所述脉冲编码调制数据进行整体衰减,直至所述平均音频幅值与所述音频幅值参考值之差的绝对值小于设定的门限值,保证所述平均音频幅值落入所述音频幅值参考值的正常波动范围内;若所述平均音频幅值小于预先设定的音频幅值参考值,且所述平均音频幅值与所述音频幅值参考值之差的绝对值大于设定的门限值,则说明所述平均音频幅值偏离所述音频幅值参考值的范围过大,则对所述脉冲编码调制数据进行整体增强,直至所述平均音频幅值与所述音频幅值参考值之差的绝对值小于设定的门限值。这样,通过对所述脉冲编码调制数据的衰减或增强,使得输出的脉冲编码调制数据的平均音频幅值均在预先设定的音频幅值参考值的上下门限值范围内,无论不同节目源的原始音量是否相同,都能保证最后输出的音量大小在一个较小的波动范围内,使用户能舒适的观看节目,不会出现输出音量忽高忽低的情况。
本实施例通过将节目源的音频数据解码成脉冲编码调制数据,并获取能体现其音频特性的音频特征值,将该音频特征值与预设的正常音频幅值参考值进行比较,根据比较结果对脉冲编码调制数据进行处理,从而将输出的音 量大小调节到正常范围内,以实现对不同节目源的原始音量进行相应的调整,使输出的实际音量保持在一个正常、稳定的范围内,避免了输出音量忽高忽低的情况,提高了用户收看节目时的舒适度,且无需用户手动操作遥控器,自动调节音量,更加智能。
参照图2,图2为本发明自动调节音量的方法第二实施例的流程示意图。
在第二实施例中,在上述步骤S30之前还包括:
步骤S40,获取当前时间,并根据用户预先设定的不同时间段与音频幅值参考值的映射关系,及当前时间所处的时间段,设定当前时间的音频幅值参考值。
本实施例中,用户还可根据自身需要预先设定不同时间段与之相对应的音频幅值参考值的映射关系,即用户可设置不同时间段对应的不同音频幅值参考值,如用户可设定13:00-14:00及22:00-8:00时间段为休息时间,作为特定时间段相应的设定特定的音频幅值参考值,该特定的音频幅值参考值较低;其他的时间段则相应的设定正常的音频幅值参考值,该正常的音频幅值参考值相对较高。
在将所述音频特征值与预先设定的音频幅值参考值进行比较,并根据比较结果对所述脉冲编码调制数据进行处理之前,获取当前时间,并根据当前时间所处的时间段及用户预先设定的不同时间段与之相对应的音频幅值参考值的映射关系设定当前时间的音频幅值参考值,如本实施例中,若当前时间处于13:00-14:00及22:00-8:00时间段,则将当前时间的音频幅值参考值设定为特定的音频幅值参考值,若当前时间处于其他的时间段,则将当前时间的音频幅值参考值设定为正常的音频幅值参考值,这样,在后续将所述音频特征值与设定的音频幅值参考值进行比较时,能根据当前时间所处的时间段的不同设定不同标准的音频幅值参考值,在处于休息时间时,设定较低的音频幅值参考值,使最终输出的实际音量在一个较低的水平,避免影响用户休息;而在其他时间段,设定正常的音频幅值参考值,使最终输出的实际音量在一个正常的水平,不影响用户收看节目,更加智能。
进一步地,若在用户收看一个节目的播放过程中进行了不同时间段之间的切换,如在节目的播放过程中进入了休息时间即特定时间段,或离开了特定时间段,则实时的根据当前时间所处的时间段及用户预先设定的不同时间段与之相对应的音频幅值参考值的映射关系更新当前时间的音频幅值参考值。这样,能在不同时间段之间进行切换时,及时地更新当前时间的音频幅值参考值,如在由特定时间段切换为其他时间段时,及时地将特定的音频幅值参考值更新为正常的音频幅值参考值,使输出音量恢复到正常的音量,以免输出音量过小影响用户收看节目;在由其他时间段切换为特定时间段时,及时地将正常的音频幅值参考值更新为特定的音频幅值参考值,使输出音量降低,以免输出音量过大影响用户休息,而无需用户手动操作遥控器调节音量,更加方便快捷。
需要说明的是,本实施例中步骤S40可以在步骤S30、S20或S10任一步骤之前,在此不作限定,图2中仅以步骤S40在步骤S30之前为例进行说明。
参照图3,图3为本发明自动调节音量的方法第三实施例的流程示意图。
在第三实施例中,在上述步骤S10之前还包括:
步骤S50,接收用户选择自动调节音量的指令,并开启自动调节音量功能。
本实施例中还包括接收用户选择自动调节音量的指令,并开启自动调节音量功能的操作。在使用时,该自动调节音量功能需要在页面设置开启,在不需要使用自动调节音量功能时,在页面设置关闭。这样,本实施例中,可以根据用户需要开启或关闭自动调节音量功能,用户在不需要使用自动调节音量功能的场合,如K歌、看球赛等需要较大音量的场合关闭自动调节音量功能,进入一般的音量处理模式,用户可根据自身需要手动调节音量,更加灵活,进一步为用户提供了方便。
需要说明的是,本实施例中步骤S50可以应用在第一实施例或第二实施例的基础上,在此不作限定,图3中仅以步骤S50应用在第一实施例的基础上为例进行说明。
本发明实施例还公开了一种计算机程序,包括程序指令,当该程序指令被计算机执行时,使得该计算机可执行上述任意的自动调节音量的方法。
本发明实施例还公开了一种载有所述的计算机程序的载体。
