 本发明的最佳实施方式
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。
参照图1，本发明一实施例的多个播放设备同步播放的方法，包括：
S1：第二播放设备接收第一播放设备通过云端服务器传递的控制码信息。
本实施例中第一播放设备为主控播放设备，通过云端服务器传递主控播放设备发送的控制码信息，实现多个播放设备同步播放各自的本地文件，控制码信息的信息量非常少，消耗的流量也很少，同时可保证各播放设备流畅地播放文件，不受网络状态的影响。本实施例的播放设备包括：安装“同步播”APP的智能手机/PAD/智能音箱等，本实施例的“同步播”APP，为基于ANDROID或者IOS的软件，具有建群、群成员管理、群消息、播放文件列表管理、文件上传下载以及指派主播等功能模块。
S2:根据所述控制码信息获取第一播放设备的第一播放进度，以及第一播放设备的本机时间与标准时间的时间差量，以得到第一播放设备发送所述控制码信息的第一标准时刻；并根据第二播放设备的本机时间与标准时间的时间差量，得到第二播放设备接收所述控制码信息的第二标准时刻。
本实施例的控制码信息包括：网络标准时间、第一播放设备与网络标准时间的时间差量、发起播放文件的发起时间、播放文件列表编号、播放文件编号以及播放状态指令等。本实施例的网络标准时间，比如东八时区的北京时间等。
S3: 根据所述第一标准时刻与第二标准时刻，得到所述控制码信息的网络延迟时间差量，将网络延迟时间差量加上第一播放进度，计算出所述第二播放设备的第二播放进度。
本步骤的第一播放设备与第二播放设备均与网络标准时间存在不同的差量，通过以网络标准时间为基准，调整第一播放设备与第二播放设备的同步播放进度，有利于提高同步播放的精度。
S4:将所述第二播放设备的播放进度切换至所述第二播放进度。
本实施例根据控制码信息控制第二播放设备的播放进度，本实施例的第二播放设备可为多个，分别接收第一播放设备通过云端发送的控制码信息，实现多个第二播放设备与第一播放设备进行同步播放。
进一步地，本实施例中，步骤S1之前，包括：
S10：第二播放设备接收加入群组的请求指令，加入所述群组。
本实施例的播放设备为智能手机，本步骤通过群主端智能手机的“同步播”APP中组件群组，安装有“同步播”APP的其他群组成员的智能手机，通过扫描二维码，或者输入注册的ID加入群组。
S11：确定所述群组中群主指派的一群组成员对应的播放设备为第一播放设备。
群主可以指派一成员的智能手机为“主播”端的第一播放设备。
S12：获取所述第一播放设备共享的同步播放文件，并存储所述同步播放文件。
第一播放设备可以创建播放文件列表，并在WIFI流量下批量上传选好的播放文件到云端服务器。其它群组成员可以在WIFI下更新第一播放设备上传的播放文件列表和播放文件到各自的智能手机进行本地存储。云端服务器会获得所有群组成员的智能手机的本地时间，并与网络标准时间比对，根据每名群组成员的智能手机的时间/网络标准时间/播放文件列表等信息生成控制码信息，控制码信息会按需要更新到所有群组成员的智能手机上。
进一步地，本实施例中，步骤S4之后，包括：
S40：接收更新的控制码信息。
本实施例中控制码信息每隔固定时间根据第一播放设备的播放进度进行更新。
S41：根据所述更新的控制码信息检验同步播放的误差。
根据实时更新的控制码信息同步监控多个播放设备的同步播放效果。
S42:根据所述误差微调所述第二播放设备的播放进度。
本实施例的智能手机的“同步播”APP运行时，通过按住手机音量+/-按键控制播放的音量增加/减小，但双击音量+/-按键可微量调整同步播放的进度时刻，以进一步提高同步播放的一致性。
进一步地，本发明实施例中，步骤S4之后，还包括：
S43：接收所述第一播放设备发送的控制码信息的控制命令。
本实施例的“主播”的智能手机的“同步播”APP具有控制码信息的控制权，可以播放/暂停/切换播放文件等，比如切换播放下一歌曲或上一歌曲等。
S44：根据所述控制命令控制所述第二播放设备的播放状态。
进一步地，本发明另一实施例中，步骤S4之后，还包括：
S45：接收所述群组的指派成为主播播放设备。
本实施例的第二播放设备可根据群主的指派变换成主播播放设备，即第一播放设备，而具有控制码信息的控制权限。
