具体实施方式
为使本领域技术人员更好地理解本公开实施例的技术方案，下面结合附图和具体实施方式对本公开实施例提供的一种播控室、播放主体结构、播控系统及播控方法、播控设备、可读存储介质作进一步详细描述。
在下文中将参考附图更充分地描述本公开实施例，但是所示的实施例可以以不同形式来体现，且不应当被解释为限于本公开阐述的实施例。反之，提供这些实施例的目的在于使本公开透彻和完整，并将使本领域技术人员充分理解本公开的范围。
本公开实施例不限于附图中所示的实施例，而是包括基于制造工艺而形成的配置的修改。因此，附图中例示的区具有示意性属性，并且图中所示区的形状例示了区的具体形状，但并不是旨在限制性的。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第 一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多次”的含义是两次或两次以上。
在描述一些实施例时，可能使用了“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。这里所公开的实施例并不必然限制于本文内容。
本文中“配置有”的使用意味着开放和包容性的语言，其不排除配置有执行额外任务或步骤的设备。
相关技术中，播控室与播放主体结构同处于一个系统中，二者之间不进行网络分隔，这种播控系统复用性和鲁棒性都较差，无法适用于大型晚会与演出的整体布置方案。
基于上述问题，第一方面，本公开实施例提供一种播控室，配置有第一总控机、主发送线路和从发送线路；第一总控机用于通过主发送线路和从发送线路分别向播放主体结构发送音视频播放控制信号。
第二方面，本公开实施例提供一种播放主体结构，配置有主播控线路和备播控线路；主播控线路和备播控线路分别用于接收播控室发送的音视频播放控制信号，并根据音视频播放控制信号播放音视频。
第三方面，本公开实施例提供一种播控系统，参照图1，为本公开实施例中播控系统的架构图，其中，包括：包括上述实施例中的播控室1和播放主体结构2；播控室1与播放主体结构2连接；播控室1，配置有第一总控机11、主发送线路101和从发送线路102；第一总控机11用于通过主发送线路101和从发送线路102分别向播放主体结构2发送音视频播放控制信号；播放主体结构2，配置有主播控线路201和备播控线路202，主播控线路201用于接收主发送线路101发送的音视频播放控制信号，并根据音视频播放控制信号播放音视频；备播控线路202用于接收从发送线路102发送的音视频播放控制信号，并根据音视频播放控制信号播放音视频。
其中，播控室1与播放主体结构2的空间位置不同。如播控室1可以是任意播控终端，播控室1可以位于任意播控终端所在位置。播放主体结构2可以是任意被控播放终端，播放主体结构2可以位于任意被控播放终端所在位置。主发送线路101和从发送线路102的配置实现了播控室1的主从备份方案，即通过两条独立的线路分别将音视频播放控制信号发送到播放主体结构2，从而保证了音视频播放控制信号的有效传递，进而保证了播控系统的鲁棒性。播控室1只需发送音视频播放控制信号，降低了对播控室1的硬件要求，适用性更广。
在一些实施例中，第一总控机11可以是平板电脑、PC机等任意能够发送音视频播放控制信号的终端。
