附图说明
图1为本发明无线多设备组合实现多声道输出音频的方法较佳实施例的流程图。
图2为本发明无线多设备组合实现多声道输出音频的系统较佳实施例的结构框图。
本发明的最佳实施方式
本发明提供一种无线多设备组合实现多声道输出音频的方法及系统,为使本发明的目的、技术方案及效果更加清楚、明确,以下对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
请参见图1,图1为一种无线多设备组合实现多声道输出音频的方法较佳实施例的流程图,如图1所示,其包括以下步骤:
S100、将主设备中多声道数字音频编码信息的数据进行解码,形成多个相互独立的单声道音频数据流;
S200、将上述多个相互独立的单声道音频数据流实时传输至多个无线接收设备;
S300、无线接收设备对所述单声道音频数据流进行无线接收;
S400、无线接收设备将其接收到的单声道音频数据流的数字信号转换为模拟信号,并通过相应的外放设备进行输出播放。
本发明实施例中将主设备中的多声道数字音频编码信息的数据进行解码,分解成多个单声道音频数据流,并将每个单声道音频数据流对应发送至无线接收设备中进行播放,不同无线接收设备组成一个家庭影院式的音场环境,如6个设备环绕一起组成可以输出5.1声道环绕立体声的系统,模拟原始音源的现场效果。本发明通过将多声道的数据流解码并传输到不同设备上,使不同设备共同组成一个家庭影院式的音场环境,实现良好的立体音和环绕声效果,使得播放声音更具立体感。
在步骤S100中,先将主设备中多声道数字音频编码信息的数据进行解码,形成多个相互独立的单声道音频数据流。一般而言,声音包含有多声道数字音频数据信息,本发明实施例中先将该多声道数字音频编码信息的数据通过主设备中的编码器进行音频数据解码,使该多声道数字音频编码信息的数据被独立实时的解码处理,形成相互独立的单声道音频数据流,这些单声道音频数据流包含有不同的音频数据信息,如组成不同声道的环绕立体声数据。
解码后,进入步骤S200,即将上述多个相互独立的单声道音频数据流实时传输至多个无线接收设备。通过主设备上的无线传输模块,将相互独立的单声道音频数据流实时地传输到不同的无线接收设备上,每一个独立的无线接收设备接收到包含有不同音频数据信息的单声道音频数据流。
在步骤S300中,无线接收设备对所述单声道音频数据流进行无线接收。并将接收到的单声道音频数据流进行进一步的处理。
进入步骤S400,无线接收设备将其接收到的单声道音频数据流的数字信号转换为模拟信号,并通过相应的外放设备进行输出播放。因为所接收到的单声道音频数据流为数字信号,其并不能直接在无线接收设备上进行播放,因此须由无线接收设备上的音频外放模块将该数字信号转化为模拟信号,形成单声道的音频模拟信号,并输出到无线接收设备外进行播放,在无线接收设备具有一定的设备布局下,可以使所播放的声音具有环绕立体声效果。
具体而言,本发明所述外放设备为喇叭扬声器。所述外放设备是设置在无线接收设备中进行声音播放的设备,本发明中的外放设备优选为无线接收设备中自带的喇叭扬声器。
本发明较佳实施例中,所述多个无线接收设备和多个相互独立的单声道音频数据流一一对应。即将多声道数字音频编码信息的数据分解成多个单声道音频数据流后,每个单声道音频数据流对应发送至一个无线接收设备中,从而使不同无线接收设备输出不同音频数据信息,这些不同音频数据信息组合起来,可以形成环绕立体声等不同声音效果,使得所播放的声音立体感强。
另外,所述多个无线接收设备还可以和一个单声道音频数据流对应。即无线接收设备可以兼容实现同一个声道的多设备输出,达到多个无线接收设备多方位输出同一个声道的声音,起到增强声音强度的目的。
优选地,所述主设备在进行解码的同时,还作为无线接收设备使用,即主设备包括至少一个无线接收设备。即主设备在将声音进行解码发送至无线接收设备的同时,其还可以接收其他主设备发送的单声道音频数据流并进行播放,提高了主设备的功能性和实用性。
另外,请参见图2,本发明还提供了一种无线多设备组合实现多声道输出音频系统较佳实施例,如图2所示,本发明所述系统包括主设备100及多个无线接收设备200;如图2所示,所述主设备100中设置有音频数据解码模块110及音频数据无线传输模块120;所述无线接收设备200包括音频数据无线接收模块210及音频外放模块220。
具体而言,所述音频数据解码模块110,用于将主设备中多声道数字音频编码信息的数据进行解码,形成多个相互独立的单声道音频数据流。
具体而言,所述音频数据无线传输模块120,用于将上述多个相互独立的单声道音频数据流实时传输到多个无线接收设备上;
具体而言,所述音频数据无线接收模块210,用于对所述单声道音频数据流进行无线接收;
具体而言,所述音频外放模块220,用于将其接收到的单声道音频数据流的数字信号转换为模拟信号,并通过相应的外放设备进行输出播放。
进一步,所述外放设备为喇叭扬声器。
进一步,所述多个音频数据无线接收模块和多个相互独立的单声道音频数据流一一对应。
进一步,所述多个音频数据无线接收模块和一个相互独立的单声道音频数据流对应。
进一步,所述主设备在进行解码的同时,还作为无线接收设备使用,即主设备包括至少一个无线接收设备。
关于上述模块单元的技术细节在前面的方法中已有详述,故不再赘述。
综上所述,本发明中的一种无线多设备组合实现多声道输出音频的方法及系统,通过主设备将多声道的数据流解码并传输到不同无线接收设备上,使不同无线接收设备共同组成一个家庭影院式的音场环境。另外,本发明的主设备和无线接收设备可以同时设置在智能设备上,使得智能设备既具有解码发送数据流,又具有接收数据流并进行播放的功能。使用不同用户的不同智能设备,可以组建一个具有家庭影院效果的使用设备环境,获得更清晰的声音、更宽阔的音场以及真实的立体环声。
应当理解的是,本发明的应用不限于上述的举例,对本领域普通技术人员来说,可以根据上述说明加以改进或变换,所有这些改进和变换都应属于本发明所附权利要求的保护范围。
