下面以一个电视设备为例对本申请的一种多声道平台音频数据传输方法进行具体描述，请参阅图2，其方法包括：
S101.识别得到每一个声道的音频数据
接收外部声源所发送的混合音频数据，并对所述混合音频数据进行解析与识别，得到每一个声道的音频数据；所述混合音频数据中至少包含有：左声道L，右声道R，左环绕SL，右环绕SR，左天空TOPL，右天空TOPR，中置Center，重低音Woofer；这八个声道的音频数据；在此处，解码器先将混合音频数据进行解码，然后对解码后的音频数据分别进行识别，分别得到八个声道的音频数据。
S102.对音频数据进行组合生成音频编码数据
将每一个声道的音频数据进行动态范围控制(DRC，Dynamic range control)和基于云端优化的存储等处理，并按预定的组合排列方式，将超过两个声道的音频数据置入一路音频通道中，生成音频编码数据。
如将左声道L，右声道R，左环绕SL，三个声道的音频数据整合到一路音频通道I2S0中，得到一路音频编码数据，将右环绕SR，左天空TOPL，右天空TOPR三个声道的音频数据整合到另一路音频通道I2S1中，得到另一路音频编码数据。
或者将左声道L，右声道R和一部分的左环绕SL音频数据整合到一路音频通道I2S0中，得到一路音频编码数据；并将另一部分的左环绕SL音频数据整合到另一路的音频通道中，通过另一路的音频通道进行传输。
S103.利用两路以上音频通道传输多声道的音频数据
通过两路以上的音频通道，对所有音频编码数据和组合排列信息进行输出；其中，I2S音频通道传输的相关原理如下：
首先I2S信号包括：MCLK，BCLK，SDATA，WS
(1)串行时钟BCLK即对应数字音频的每一位数据，BCLK都有1个脉冲。
BCLK的频率＝2×采样频率×采样位数＝2*48KHz*16bit＝1.536MHz
(2)帧时钟WS用于切换左右声道的数据。WS为“1”表示正在传输的是左声道的数据，为“0”则表示正在传输的是右声道的数据。WS的频率等于采样频率。
(3)串行数据SDATA，就是用二进制补码表示的音频数据。
(4)MCLK主时钟即，系统时钟，目的是为了使系统间能够更好地同步，MCLK的频率是采样频率的256倍或384倍,48KHz*256＝12.288MHz。
I2S格式的信号无论有多少位有效数据，数据的最高位总是出现在WS变化，即一帧开始后的第2个BCLK脉冲处。这就使得接收端与发送端的有效位数可以不同。如果接收端能处理的有效位数少于发送端，可以放弃数据帧中多余的低位数据；如果接收端能处理的有效位数多于发送端，可以自行补足剩余的位。这种同步机制使得数字音频设备的互连更加方便，而且不会造成数据错位。
随着技术的发展，在统一的I2S接口下，出现了多种不同的数据格式。根据SDATA数据相对于WS和BCLK的位置不同，分为左对齐、I2S格式和右对齐。为了保证数字音频信号的正确传输，发送端和接收端应该采用相同的数据格式和长度。当然，对I2S格式来说数据长度可以不同。
字段(声道)选择(WS)命令选择线表明了正在被传输的声道。
WS＝0，表示正在传输的是左声道的数据。
WS＝1，表示正在传输的是右声道的数据。
WS可以在串行时钟的上升沿或者下降沿发生改变，并且WS信号不需要一定是对称的。在从属装置端，WS在时钟信号的上升沿发生改变。WS总是在 最高位传输前的一个时钟周期发生改变，这样可以使从属装置得到与被传输的串行数据同步的时间，并且使接收端存储当前的命令以及为下次的命令清除空间。
S104.根据组合排列信息得到每一个声道的音频数据
接收所有音频编码数据，并按所述组合排列信息，将所接收到的音频编码数据进行解码并复原，得到每一个声道的音频数据；由于组合排列信息记录有每个声道的音频数据在音频通道和音频编码数据中的位置，故根据组合排列信息在各音频通道中对音频编码数据的不同部分进行截取，即可得到对应声道的音频数据，如：左声道L的音频数据被放置于I2S0的左声道前端的16bit中，则将I2S0的左声道前端的16bit进行截取，即可到左声道L的音频数据。
由于不同芯片方案系统内部I2S架构方式不同，I2S协议中有MCLK，BCLK，WS，Data四组信号。其中MCLK为主时钟信号，BCLK为时钟信号，WS为声道选择，Data为声道数据，故基于芯片架构的不同，I2S传输的形式也不同，在一些实施例中，列举两种接收方案：
接收方式一:
当芯片I2S输出供一路CLK时，接收端采用边收边拆的形式。
不同芯片I2S输出通道不同，当机芯端的2路I2S输出是共用一路MCLK，BCLK，WS的，也就是单路CLK采集。单路CLK由机芯端发出给音频协处理器芯片，音频协处理器芯片根据单路CLK，采集机芯端按照不同编码排列形式发送出的多个声道的音频数据，其采样速率不同。由于音频数据是同时发送到接收端，因此音频协处理器芯片在接收音频数据的同时，根据机芯端提供的多声道数据编码序列进行拆解。
但是，如机芯芯片3路I2S共用一路CLK的话，就会存在数据传输过程中，一旦I2S共用的CLK出错，就会造成3路I2S数据传输被接收到的数据出错，可能存在声音异常等情况发生。其中，CLK出错来源为：软件的延迟，外围信号的干扰，硬件电路等。
为此，本实施例中提供另一种接收方式，即接收方式二:
先等待3路I2S数据全部处理好后，再同时发送；然后初始化接收的声音数据，即采集3路初始化声音数据的第一位，以第一位有效信号当做等待音的MCLK。由于3路CLK共用，故用3路CLK分别去发送数据，这样就很大程度上降低因某一路CLK异常导致其数据出错。
由于相关技术中，电视设备的主芯片中最多只能输出3路I2S数据，也就是最多实现6个声道的音频数据传输，而在本申请中至少要实现8个声道的音频数据输出，故在本方案中对8个声道的音频数据进行重编码，得到6声道的音频编码数据。
相应的，将6声道的音频编码数据传输给一个音频协处理器芯片，该芯片能够按照重编码器的编码规则，将其解码并还原成8声道的音频数据，并传输给功放器，从而实现多声道输出的效果。
下面以一个调整采样位宽，不调整采样频率的工作方式的实施例对本申请的一种多声道平台音频数据传输方法进行具体描述，即其保持采样频率为48KHZ，并将原来的采样位宽从16bit调整为24bit的工作方式，请参阅图3至图5，其包括：
S201.识别得到每一个声道的音频数据
接收外部声源所发送的混合音频数据，并对所述混合音频数据进行解析与 识别，得到每一个声道的音频数据；所述混合音频数据中至少包含有：左声道L，右声道R，左环绕SL，右环绕SR，左天空TOPL，右天空TOPR，中置Center，重低音Woofer；这八个声道的音频数据；在此处，解码器先将混合音频数据进行解码，然后对解码后的音频数据分别进行识别，分别得到八个声道的音频数据。
S202.对音频数据进行重新编号
将预定的声道的音频数据进行拆分，并将所有声道的音频数据进行重新编号；
其具体为：将解码后的8声道的音频数据进行重新编号，分别为cache1：L(16bit)，cache2：R(16bit)，cache3:LS(16bit)，cache4:RS(16bit)，cache5:FTL(16bit)，cache6:FTR(16bit)，cache7:SWH(高8bit位)Cache8:SWL(低8bit位)，cache9:CH(高8bit位)，cache10:CL(低8bit位)。
将这些分组数据存入缓冲器中，在通过驱动调用底层缓冲器中的数据到堆栈中，进行如图4所示的数据排列，通过BCLK时钟，通过I2SData传输出去；其中，为了不影响音效体验效果，一般采用将次要声道的音频数据，如中置音，重低音进行拆分，这样做的优点在与CLK受到干扰或异常时，采集的主声道以及环绕音，天空音不至于丢失以及错误。
S203.调整采样位宽生成音频编码数据
改变所述音频通道中一条音频编码数据的采样位宽，并按照改变后的采样位宽，在一条音频编码数据中置入相适应数量声道的音频数据；
其具体为：把原有一路I2S输出16bit@48Khz音频编码数据，改为24bit@48KHZ音频编码数据，在本实施例中其保持采样频率不变，更改采样位 宽，由原来的16bit变更为24bit。
以一路I2S 2ch为例，WS(LRCK)＝0时采集左声道数据，WS(LRCK)＝1时采集右声道数据，由于一路I2S音频通道最多可支持32bit的位宽，故其WS最多可以采集32bit左右声道数据。
在本实施例中，其将16bit的Ch0声道的音频数据，放置于I2S0中的左声道，将16bit的Ch2声道的音频数据，放置于I2S0中的右声道；并将Ch1声道的音频数据拆解为2个8bit的部分，再分别放置于I2S0中的左、右声道中；故I2S0中的左、右声道均为24bit的位宽。
S204.判断是否均生成有音频编码数据
对所生成的音频编码数据进行缓存，判断所有的需要进行传输的音频通道中是否均生成有音频编码数据，若均生成有音频编码数据，则进行步骤S205，通过音频通道，对所有音频编码数据和组合排列信息进行输出；若未生成有音频编码数据，则等待所有的需要进行传输的音频通道均生成有音频编码数据。
由于输出的3路I2S芯片内部架构是每一组I2S有单独的MCLK，WS，BCK，Data，但更为重要的是要保证3路I2S的MCLK同步。
在本实施例中采用等待发送的工作方式，就是等待3路I2S数据全部处理好后，同时发送；初始化发新声音，采集3路初始化音的第一位，以第一位有效信号当作等待音的MCLK。3路CLK共用，用3路CLK分别取发送数据，这样就很大程度上降低因某一路CLK异常导致其数据出错。
S205.利用三路音频通道传输多声道的音频数据
通过三路音频通道，对所有音频编码数据和组合排列信息进行输出；每一路音频通道可传输三路音频数据，故在本实施例中，最多可对9个声道的音频 数据进行传输；当需要传输的音频数据为8个声道时，可按图4所示，在一路音频通道的左右声道中各置入一个声道的音频数据，不加入被拆分的音频数据。
S206.接收所有音频编码数据并进行缓存
接收所有音频编码数据，对所有接收到的音频数据进行缓存。其具体为：主芯片将3路I2S音频通道中的24bit数据全部传输给音频协处理器芯片，音频协处理器芯片不进行边收边拆，其将24bit数据进行缓存在缓存器中；
主芯片机芯端将8声道的音频数据变为6声道的编码数据的编码排列方式提供给音频协处理器芯片；
S207.根据组合排列信息得到每一个声道的音频数据
按照所述组合排列信息，从音频编码数据中的预定位置上截取预定采样位宽的音频数据，并为所截取到的音频数据添加上为对应声道的属性信息。待三组数据缓存后，由于音频协处理器芯片端内部本身存在时钟信号，分别采集3路数据的第一位为有效MCLK信号，采集24bit数据的前16位有效数据，并将16位有效数据进行组合，得出主声道，环绕音，上出音的音频数据。
在采集3路24bit第一位有效数据为有效的MCLK信号，采集24bit数据后8bit数据，重新进行数据组合，得出中置音，重低音等音频数据
将还原出的原有多声道5.1.2的数据通过4路I2S输送给功放端，实现多声道音效效果的目的。
请参看图6，在另一个实施例中，还可以在不调整采样频率的情况下，将采样位宽从16bit调整为32bit，故一路I2S音频通道中可传输4个声道的音频信号，此方式编码可以保证2路I2S最多支持8个声道的音频数据，将多路音频数据全部传给协音频处理器，机芯端将编码方式告知协音频处理器，协音频处 理器将2路I2S输入的音频数据进行复原，通过其本身的多路I2S，分别传给对应的功放芯片，输出5.1.2音效效果的声音。在本实施例中，只需要利用到2路I2S音频通道，其具有良好的扩展性。

S502.调整采样频率生成音频编码数据
改变所述音频通道中一条音频编码数据的采样频率，并按照改变后的采样频率，在一条音频编码数据中置入相适应数量声道的音频数据；其具体为：采样位宽不变，采样频率提升为96KHz，其对应的BCLK频率提升为：2*96KHz*16bit＝3.072MHz，每个BCLK上升沿采集的数据就变成32bit。
以一路I2S的2声道音频数据为例，WS(LRCK)＝0时采集左声道数据，WS(LRCK)＝1时采集右声道数据，其WS最多可以采集32bit左右声道数据，改变采样频率有两种方式，一种为更改BCLK的频率单沿采集，一种BCLK频 率不变，采用双沿采集，此种方式采集到的数据L通道，采集32bit数据，R通道采集32Bit数据，采集速率96KHz。
S503.判断是否均生成有音频编码数据

由于输出的3路I2S芯片内部架构是每一组I2S有单独的MCLK，WS，BCK，Data，但更为重要的是要保证3路I2S的MCLK同步。
在本实施例中采用等待发送的工作方式，就是等待3路I2S数据全部处理好后，同时发送；初始化发新声音，采集3路初始化音的第一位，以第一位有效信号当作等待音的MCLK。3路CLK共用，用3路CLK分别取发送数据，这样就很大程度上降低因某一路CLK异常导致其数据出错。
S504.利用三路音频通道传输多声道的音频数据

S506.接收所有音频编码数据并进行缓存
接收所有音频编码数据，对所有接收到的音频数据进行缓存。其保持位宽不变，改变采样频率，此种方式传输的依旧为16bit数据48KHZ，在机芯端多路信道的进行压缩采样，由16bit48HKZ变为16bit@96KHZ信号，此种方式就可以将4ch数据通过1路I2S传输出去，3路IS输出最大可支持12个声道16bit 48KHZ数据的输出。

在本实施例中，若传输8声道的数据，实际上可以采用两路传输，96HZ的采样率就能实现。若更多声道的数据，可以再增加采样率即可。
在另一个实施例中，可同时对采样位宽和采样频率分别进行调整，使得采样位宽从原来的16bit调整为24bit，采样频率从原来的48KHz调整为96KHz，其对应的BCLK频率提升为：2*96KHz*24bit＝4.608MHz，每个BCLK上升沿采集的数据就变成32bit。
