【附图说明】
为了更清楚地说明本申请实施例的技术方案，下面将对本申请实施例中所需要使用的附图作简单地介绍。显而易见地，下面所描述的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本申请一种数据传输方法第一实施方式的流程图；
图2是本申请一种数据传输方法第二实施方式的流程图；
图3是本申请一种数据传输方法第三实施方式的流程图
图4是本申请一种数据传输***实施方式的示意图；
图5是本申请一种数据传输方法的电子设备第一实施例的示意图；
图6是本申请一种接收装置实施方式的示意图；
图7是本申请一种数据传输方法的电子设备第二实施例的示意图。
【具体实施方式】
参阅图1，本申请一种数据传输方法实施方式包括：
步骤101：生成第一传输数据包和第二传输数据包，其中，所述第一传输数据包与所述第二传输数据包包含有相同的数据内容；
虽然第一传输数据包与所述第二传输数据包包含有相同的数据内容，但是为了使第一传输数据包和第二传输数据包适应不同的传输信道，第一传输数据包中所述数据内容的编码方式可以不同于所述第二传输数据包中所述数据内容的编码方式，例如：可以设置第一、第二两个预设封装算法，第一预设封装算法是对应第一传输信道，第二预设封装算法是对应第二传输信道，根据第二预设封装算法，将数据内容封装至第二传输数据包，以及根据第一预设封装算法，将数据内容封装至第一传输数据包，当然，为了方便判断第一传输数据包和第二传输数据包是否包含相同的数据内容，还可以对数据内容进行编号，并且把编号封装至传输数据包中。
进一步的，为了方便生成两个包含相同的数据内容的传输数据包，可以先 生成数据内容的副本，然后根据数据内容生成第一传输数据包，再根据数据内容的副本生成第二传输数据包。
步骤102：通过第一传输信道向接收装置发送第一传输数据包；
步骤103：通过第二传输信道向所述接收装置发送第二传输数据包；
需要说明的是：步骤101至103均是由发送装置执行的，而第一传输信道和第二传输信道是指发送装置与接收装置之间建立的数据通道，在本实施例中，第一传输信道与所述第二传输信道位于不同的频段上，例如：第一传输信道为2.4G，第二传输信道为900M。发送装置将生成的第一数据包和第二数据包分别从第一传输信道和第二传输信道发出，由于第一传输信道和第二传输信道是独立的，因此，第一传输数据包和第二传输数据包相互不受影响。
本申请实施例中，发送装置通过将携带相同的数据内容分别通过第一传输信道和第二传输信道进行传输，保证第一传输数据包和第二传输数据包的独立性，即使其中一个传输数据包在传输的过程出现问题时，接收装置可以使用另一个传输数据包进行处理，保证数据传输的时效性，很好地避免了在单通道传输中，若传输数据包出现问题时，需要接收装置和发送装置同步跳传到另一传输信道，重新传输传输数据内容，数据内容出现严重延时的情况。当然，在其它替代实施例中，发送装置也可以生成三个、四个或者更多的携带相同的数据内容的传输数据包，并且每一传输数据包对应一传输信道进行传输。
由于第一传输数据包和第二传输数据包是携带相同的数据内容，为了避免接收装置重复使用相同的数据内容，接收装置可以根据第一传输数据包和第二传输数据包之中最早到达的传输数据包进行处理，则请参阅图2，方法还包括：
步骤201：所述接收装置确定所述第一传输数据包与所述第二传输数据包之中最早接收到的数据包；
接收装置根据最早接收到的数据包进行处理，有利于保证接收装置获取数据内容的时效性，尤其是在线流媒体传输中，数据内容的实时性是非常重要，数据内容的延伸容易引起卡顿。
而另外，接收装置在确定所述第一传输数据包与所述第二传输数据包之中最早接收到的数据包可以通过数据存储器进行过渡判断，具体如下：
判断所述第一传输数据包是否正确，若正确接收装置将对数据包进行解析，不正确则丢弃该数据包；并判断数据存储空间是否存储有与所述第一传输数据 包所携带的数据内容相同的数据，若存储空间是否存储没有与所述第一传输数据包所携带的数据内容相同的数据则将数据内容存储至存储空间，否则丢弃该数据包。
步骤202：所述接收装置对所述最早接收到的数据包进行处理；
进一步的，接收装置在通过第一传输信道和第二传输信道接收数据包时，还可以对数据包的正确性进行判断，当数据包不正确时直接掉弃。
在本申请实施例中，发送装置分别通过第一、第二两条传输信道向接收装置发送携带有相同的数据内容的第一传输数据包和第二传输数据包，接收装置在通过第一、第二两条传输信道接收至第一传输数据包和第二传输数据包之后，根据第一传输数据包和第二传输数据包之中最早到达的传输数据包进行处理，有利于保证接收装置获取数据内容的时效性，很好地避免了在单通道传输中，若传输数据包出现问题时，需要接收装置和发送装置同步跳传到另一传输信道，重新传输传输数据内容，造成数据内容出现严重延时的情况。
请参阅图3，图3是一种数据传输方法的第二实施例的流程图，一种数据传输方法，包括：
步骤301：通过第一传输信道和第二传输信道接收发送装置发送的数据包；
第一传输信道和第二传输信道是发送装置和接收装置之间用于传输数据的信道，而发送装置向接收装置发送数据内容时，分别通过第一传输信道和第二传输信道传输携带该数据内容的数据包，简而言之，一数据内容分别通过第一传输信道和第二传输信道向接收装置发送两次。
步骤302：解析所述数据包，判断所述数据包是否正确；若正确则进入步骤303，否则进入步骤305；
解析所述数据包，获取所述数据包所携带的数据内容。另外，不同传输信道，其对传输数据的格式可以不相同的，因此，第一传输信道可以对应第一预设解析算法，第二传输信道可以对应第二预设解析算法，解析第一传输数据包的方式也是按第一预设解析算法进行的，第一预设解析算法与第二预设封装算法相对应的。
步骤303：如果所述数据包是正确的，确定首次接收到的所述数据包；
其中，校验数据包是否正确的方式可以有多种，例如：在数据包中设置校验码，通过校验码校验数据包是否正确，或者，通过判断数据包是否包含首尾 封装标识判断数据包是否正确。
步骤304：对首次接收到的所述数据包进行处理；
确定首次接收到的数据包的方式也可以有多种，例如：记录每一个数据包的接收时间，当发现接收到两个数据内容相同的数据包，根据接收时间判断哪一数据包时首次接收到的数据包。为了减少接收装置存储数据的存储量，也可能在接收到数据包时，并且判断到数据包是否正确时，判断数据存储空间是否存在有相同的数据包，若没有，则将数据包存储至数据存储空间，若有，则丢弃的该数据包，后续对数据包进行处理，直接从数据存储空间中提取数据包进行处理，有效地避免地重复处理数据。当然，在其它替代实施例中，也可以通过记录表的形式，记录接收到的待传数据块，当接收装置从记录表中找到已经接收过相同的待传数据块时，将该待传数据块丢弃。
步骤305：如果所述数据包是不正确的，则丢弃所述数据包；
当接收装置在丢弃数据包中确定存在两个包含相同的数据内容的数据包时，接收装置也可以向发送装置发送数据重传消息。
需要说明的是：发送装置在传输数据内容时，数据内容可以是由原始数据分割得到的，并且每一个数据内容均设置有顺序编号，传输数据包中除了包含数据内容之外，还包括对应的顺序编号。接收装置在接收到数据内容和顺序编号之后，根据顺序编号和数据内容还原出原始数据。
在本申请实施例中，接收装置在通过第一、第二两条传输信道接收至第一传输数据包和第二传输数据包之后，根据第一传输数据包和第二传输数据包之中最早到达的传输数据包进行处理，有利于保证接收装置获取数据内容的时效性，很好地避免了在单通道传输中，若传输数据包出现问题时，需要接收装置和发送装置同步跳传到另一传输信道，重新传输传输数据内容，造成数据内容出现严重延时的情况。
本申请还提供数据传输***的实施例,请参阅图4，数据传输***400包括：发送装置401和接收装置402。发送装置401包括：生成模块4011和发送模块4012。接收装置402包括：确定模块4021和处理模块4022。生成模块4011，用于生成第一传输数据包和第二传输数据包，其中，所述第一传输数据包与所述第二传输数据包包含有相同的数据内容。发送模块4012，用于通过第一传输信道向接收装置发送第一传输数据包，第二传输信道向所述接收装置发送第二 传输数据包。确定模块4021，用于所述接收装置确定所述第一传输数据包与所述第二传输数据包之中最早接收到的数据包。处理模块4022，用于所述接收装置对所述最早接收到的数据包进行处理。生成模块4011、发送模块4012、确定模块4021和处理模块4022都可以分别是处理器，处理器通过运行从而执行各种功能应用以及数据处理，即实现数据传输的处理方法。
具体的，生成模块4011可以对数据内容进行复制，生成数据内容的副本，两个数据内容生成两个数据包，分别在第一传输信道和第二传输信道上传输。为了使第一传输数据包和第二传输数据包适应不同的传输信道，第一传输数据包中所述数据内容的编码方式可以不同于所述第二传输数据包中所述数据内容的编码方式，例如：可以设置第一、第二两个预设封装算法，第一预设封装算法是对应第一传输信道，第二预设封装算法是对应第二传输信道，根据第二预设封装算法，将数据内容封装至第二传输数据包，以及根据第一预设封装算法，将数据内容封装至第一传输数据包，当然，为了方便判断第一传输数据包和第二传输数据包是否包含相同的数据内容，还可以对数据内容进行编号，并且把编号封装至传输数据包中。
在本申请实施例中，发送装置通过将携带相同的数据内容分别通过第一传输信道和第二传输信道进行传输，保证第一传输数据包和第二传输数据包的独立性，即使其中一个传输数据包在传输的过程出现问题时，接收装置可以使用另一个传输数据包进行处理，保证数据传输的时效性，很好地避免了在单通道传输中，若传输数据包出现问题时，需要接收装置和发送装置同步跳传到另一传输信道，重新传输传输数据内容，数据内容出现严重延时的情况。
