本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
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。
本发明提供一种电视机的音视频播放方法，参照图1，在一实施例中，所述电视机的音视频播放方法包括以下步骤：
步骤S10，初始化电视机的硬件驱动；
本实施例中，当用户打开电视机时，电视机的硬件驱动即初始化运行CPU并加载执行bootloader程序，booltloader加载执行kernel后进行各驱动的初始化，各驱动的初始化包括但不限于GPIO （General Purpose Input Output，通用输入/输出口）的初始化，显示屏驱动的初始化，USB驱动的初始化，IIC（Inter-Integrated Circuit，集成电路总线）的初始化，声音功放的初始化等。其中，bootloader程序是嵌入式系统在加电后执行的第一段代码，在它完成CPU和相关硬件初始化后，再将操作系统映像或固化的嵌入应用程序装到内存中，再跳转到操作系统所在的空间，启动操作系统运行。Kernel为操作系统内核，通常运行进程，并提供进程间通信和同步等。
步骤S20，设置GPIO接口的电位状态为第一电平，并播放开机音视频；
本实施例中，电视机设置GPIO接口的电位状态为第一电平，本优选实施例中，所述第一电平可以设置为高电平，GPIO的配置可以通过驱动的接口进行设置，比如：设置为DRV_GPIO_SetLevel（101, 1），其中，101表示：GPIO pin脚，1表示高电平。当然，在其他实施例中，所述第一电平也可以设置为低电平。
本实施例中，可以理解的是，开机音视频在正式播放前需要进行以下处理，如创建播放器、对开机视频流进行解码处理、对开机视频资源进行储存地址的分配、对音频和视频进行同步处理等，当然，在其他实施例中，还可以进行其他处理，并不限于本实施例。
步骤S30，监测所述GPIO接口的电位状态变化；
本实施例中，GPIO的状态变化可以通过驱动接口如DRV_GPIO_Get Level来获取。当电视机监测到GPIO接口的电位状态发生变化时，此时可以触发中断，但是并不限于中断方式，如GPIO的状态变化也可以使用软件查询的方式进行监控。通过使用GPIO进行软硬件结合的方式，可以触发中断来进行处理。其中，中断是指CPU在正常运行程序的过程中，由于预选安排或发生了各种随机的内部或外部事件，使CPU中断正在运行的程序，而转到为相应的服务程序中去，本优选实施例中，该服务程序即为控制电视节目播放通道的音视频输出的程序。
其中，可以根据所述开机音视频的播放状态，将所述GPIO接口的电位状态设置为第二电平。当开机音视频的播放状态为播放完毕时，再次设置GPIO接口，将GPIO接口的电位状态设置成第二电平（与开机音视频开始播放时的状态相反即可），此时会触发GPIO电位状态改变的通知，可以通过中断方式进行即刻响应，而不存在软件查询导致的延迟问题，解决了电视节目播放的音视频不同步的问题，从而可以满足用户更好的使用智能电视收看电视节目的需求。
步骤S40，在监测到所述GPIO接口的电位状态由第一电平切换为第二电平时，播放电视节目音视频。
本实施例中，在电视机监测到GPIO接口的电位状态由第一电平切换为第二电平时，也即GPIO接口的电位状态由高电平切换为低电平时，将信号源由开机视屏的播放通道切换到电视节目的播放通道上，以便让电视节目的画面在电视机屏幕上进行显示，电视节目的声音在电视机喇叭上进行输出。具体对视频video的控制可以通过接口video_mute来进行设置：设置打开video显示参数为mute=0，设置关闭video显示参数为mute = 1，对音频audio的控制可以通过接口audio_mute来进行设置：设置打开audio参数为 mute = 0，设置关闭audio参数为mute = 1。
本发明提供的电视机的音视频播放方法，首先通过初始化电视机的硬件驱动，然后设置GPIO接口的电位状态为第一电平，并播放开机音视频，再监测所述GPIO接口的电位状态变化，并在监测到所述GPIO接口的电位状态由第一电平切换为第二电平时，播放电视节目音视频；其中，根据所述开机音视频的播放状态，将所述GPIO接口的电位状态设置为第二电平。这样，不存在软件查询由于等待CPU而导致的延迟问题，可以解决电视机开机音视频播放结束时，电视节目播放的音视频不同步问题，以提高用户观看电视的体验。
在一实施例中，如图2所示，在上述图1所示的基础上，所述步骤S20包括：
步骤S201，设置所述GPIO接口的电位状态为第一电平；

步骤S202，获取开机视频数据；
步骤S203，打开第一播放通道，并通过所述第一播放通道播放所述开机视频数据。
本实施例中，获取的开机视频数据包括音频和视频数据，通过打开第一播放通道来播放所述音频和视频数据。可以理解的是，所述开机视频数据在播放前还需进行以下处理，如创建播放器、对开机视频流进行解码处理、对开机视频资源进行储存地址的分配、对音频和视频进行同步处理等，当然，在其他实施例中，还可以进行其他处理，并不限于本实施例。
本实施例中，开机视频的画面在电视机屏幕上进行显示，开机视频的声音在电视机喇叭上进行输出。
在一实施例中，如图3所示，在上述图2所示的基础上，所述步骤S203之后还包括：
步骤S204，在所述开机视频的播放状态为数据播放完毕时，关闭所述第一播放通道；
本实施例中，当所述开机视频的播放状态为数据播放完毕时，可以关闭所述第一播放通道，具体表现为无声音，电视机屏幕显示为最后一帧数据或为纯色（黑色或蓝色）。
本实施例中，开机视频播放结束时，所述第一播放通道在播放结束时产生EOS消息（End off spring，流结束消息），以表示播放结束，而CPU在接收到所述EOS消息时，进而再次设置GPIO接口的电位状态。
步骤S205，设置所述GPIO接口的电位状态为第二电平。
本实施例中，再次设置所述GPIO接口，将GPIO接口的电位状态设置成第二电平如低电平（与开机视频开始播放时的状态相反即可），触发GPIO电位状态改变的通知（可以为中断，也可以为回调）或电视节目播放的流程中监测GPIO电位状态变化（此方法可能有短暂的黑屏或蓝屏或为开机视频的最后一帧画面）。
在一实施例中，如图4所示，在上述图1所示的基础上，所述步骤S40包括：

本实施例中，电视机的第二播放通道默认设置为关闭状态，当监测到所述GPIO接口的电位状态由第一电平切换为第二电平时，如由高电平切换为低电平或由低电平切换为高电平时，则会打开第二播放通道。
步骤S402，通过所述第二播放通道播放所述电视节目音视频。
本实施例中，通过所述第二播放通道播放所述电视节目音视频，具体为电视节目的画面在电视机屏幕上进行显示，电视节目的声音在电视机喇叭上进行输出。
