在本公开实施例中，第一播放控制设备11和第二播放控制设备12分别与显示装置13连接，用于控制同一显示装置13显示。这里，第一播放控制设备11和第二播放控制设备12中的一个为主播放控制设备，另一个为备播放控制设备。在第一播放控制设备11和第二播放控制设备12中的一个无法正常工作时，由另一个控制显示装置13进行显示，以避免显示中断，保证播放控制系统的可靠性。
例如，当第一供电电路21断电时，第二供电电路22正常供电，第二播放控制设备12处于被供电状态，第二播放控制设备12可以继续控制显示装置13进行正常显示。又例如，当第二供电电路22断电时，第一供电电路21正常供电，第一播放控制设备11处于被供电状态，第一播放控制设备12可以继续控制显示装置13进行正常显示。因此，采用两路供电电路和两个播放控制设备，可以提高播放控制系统的可靠性。
并且，当第一目标供电电路断电时，通过电源30为第一目标播放控制设备供电，可以使得第一播放控制设备11和第二播放控制设备12均处于被供电状态。这样，当电源30断电或 者第一供电电路21和第二供电电路22中的另一个也断电时，第一播放控制设备11和第二播放控制设备12中的一个还可以处于供电状态，继续控制显示装置13进行正常显示，可以进一步提高播放控制系统的可靠性。
本公开实施例中，在第一供电电路断电，切换电源为第一播放设备供电期间，由于第二供电电路为第二播放设备供电，显示装置仍然可以处于正常显示状态。同样地，在第二供电电路断电，切换电源为第二播放设备供电期间，由于第一供电电路为第一播放设备供电，显示装置仍然可以处于正常显示状态。这样，第一播放控制设备和第二播放控制设备中的至少一个可以被供电，从而可以保证显示装置始终处于正常显示状态，提高了播放控制系统的可靠性。
示例性地，第一播放控制设备11和第二播放控制设备12为OPS(Open Pluggable Specification，开放式可插拔规范)设备。例如，OPS设备为个人计算机等。示例性地，显示装置13包括显示屏，例如LED(Light Emitting Diode，发光二极管)显示屏等。示例性地，电源为UPS(Uninterrupted Power Supply，不间断电源)、蓄电池或者其他形式的电池。
可选地，本公开实施例中，电源30还被配置为，在第一目标供电电路恢复供电后，停止为第一目标播放控制设备供电。
例如，第一供电电路21断电后，通过电源30为第一播放控制设备11供电。当第一供电电路21恢复供电后，停止通过电源30为第一播放控制设备11供电，由第一供电电路21继续为第一播放控制设备11供电。
在一些示例中，第一播放控制设备11和第二播放控制设备12上分别设置有第一接头和第二接头。示例性地，第一接头和第二接头为快接头。快接头一般指快速接头，是一种不需要工具就能实现连接或断开的接头。电源30通过第一接头与第一播放控制设备11连接，电源30通过第二接头与第二播放控制设备12连接。
在另一些示例中，电源30与第一播放控制设备11之间以及电源30与第二播放控制设备12之间分别连接有第一开关单元和第二开关单元。电源30为第一播放控制设备11供电时，第一开关单元处于导通状态，电源30为第二播放控制设备12供电时，第二开关单元处于导通状态。
在又一些示例中，第一播放控制设备11和第二播放控制设备12上分别设置有第一接头和第二接头，电源30通过第一接头与第一播放控制设备11连接，电源30通过第二接头与第二播放控制设备12连接。同时，电源30与第一播放控制设备11之间以及电源30与第二播放控制设备12之间分别连接有第一开关单元和第二开关单元。
可以通过断开电源30与第一接头之间的连接，以停止电源30为第一播放控制设备11供电；通过断开电源20与第二接头之间的连接，以停止电源30为第二播放控制设备12供电。或者，可以通过断开第一开关单元，以停止电源30为第一播放控制设备11供电；通过断开 第二开关单元，以停止电源30为第二播放控制设备12供电。
由于电源30的电量有限，若一直采用电源30为播放控制设备供电，电源30可能会因为电量不足而无法为播放控制设备供电。因此，在第一目标供电电路恢复供电后，断开电源供电，可以进一步提高播放控制系统的可靠性。
图2是本公开实施例提供的一种显示装置的结构示意图。如图2所示，该显示装置包括第一发送单元131、第二发送单元132、第一接收单元133、第二接收单元134和显示屏135。
第一发送单元131与第一播放控制设备11连接，第一发送单元131与第一接收单元133连接，第一接收单元133与显示屏135连接。第一播放控制设备11向第一发送单元131发送图像数据，第一发送单元131对图像数据进行处理并将处理后的图像数据发送至第一接收单元133，第一接收单元133将图像数据转换成驱动信号，以驱动显示屏135进行显示。
第二发送单元132与第二播放控制设备12连接，第二发送单元132与第二接收单元134连接，第二接收单元134与显示屏135连接。第二播放控制设备12向第二发送单元132发送图像数据，第二发送单元132对图像数据进行处理并将处理后的图像数据发送至第二接收单元134，第二接收单元134将图像数据转换成驱动信号，以驱动显示屏135进行显示。
示例性地，第一发送单元131和第二发送单元132为发送卡，第一接收单元133和第二接收单元134为接收卡。
示例性地，第一播放控制设备11与第一发送单元131之间以及第二播放控制设备12与第二发送单元132之间通过HDMI(High Definition Multimedia Interface，高清多媒体接口)连接。第一发送单元131与第一接收单元133之间以及第二发送单元132与第二接收单元134之间通过ETH(Ehternet，以太网)接口连接。
需要说明的是，本公开实施例中，当第一播放控制设备11和第二播放控制设备12同时被供电时，由第一播放控制设备11和第二播放控制设备12中的一个控制显示装置显示；当第一播放控制设备11被供电且第二播放控制设备12未被供电时，由第一播放控制设备11控制显示装置显示；当第一播放控制设备11未被供电且第二播放控制设备12被供电时，由第二播放控制设备12控制显示装置显示。
图3是本公开实施例提供的另一种播放控制系统的结构示意图。如图3所示，该系统包括第一播放控制设备11、第二播放控制设备12、第一供电电路21、第二供电电路22、第三供电电路23、第四供电电路24和电源30。
其中，第一供电电路21和第三供电电路23与第一播放控制设备11连接。第一供电电路21用于利用第一市电为第一播放控制设备11供电，第三供电电路23用于利用第二市电为第一播放控制设备11供电。
第二供电电路22和第四供电电路24与第二播放控制设备12连接。第二供电电路22用于利用第一市电为第二播放控制设备12供电，第四供电电路24用于利用第二市电为第二播 放控制设备12供电。
第一市电和第二市电属于相同的提供商和/或供电站。或者，第一市电和第二市电属于不同的提供商和/或供电站。示例性地，第一市电和第二市电为220V三相交流电。
示例性地，第一供电电路21、第三供电电路23、第二供电电路22和第四供电电路24为220V供电箱，输出220V交流电。
需要说明的是，在同一时刻，第一供电电路21和第三供电电路23中的至少一个为第一播放控制设备11供电。第二供电电路22和第四供电电路24中的至少一个为第二播放控制设备12供电。
第一供电电路21和第三供电电路23中的一个断电时，可以采用第一供电电路21和第三供电电路23中的另一个为第一播放控制设备11供电。第二供电电路22和第四供电电路24中的一个断电时，可以采用第二供电电路22和第四供电电路24中的另一个为第二播放控制设备12供电。因此，为每个播放控制设备设置两路供电电路，可以进一步提高播放控制系统的可靠性。
在一些实施方式中，通过第一供电电路21为第一播放控制设备11供电，同时，通过第二供电电路22为第二播放控制设备12供电。第一市电和第二市电属于不同的供应商和/或供电站。
电源30被配置为，在第一目标供电电路断电时，为第一目标播放控制设备供电。其中，第一目标供电电路为第一供电电路21和第二供电电路22中的一个。第一目标供电电路为第一供电电路21时，第一目标播放控制设备为第一播放控制设备11，第一目标供电电路为第二供电电路22时，第一目标播放控制设备为第二播放控制设备12。
第二目标供电电路被配置为，在第一目标供电电路断电且电源30为第一目标播放控制设备供电时，停止为第二目标播放控制设备供电。其中，第二目标供电电路为第一供电电路21和第二供电电路22中，除第一目标供电电路之外的供电电路，第二目标播放控制设备为第二目标供电电路连接的播放控制设备。
第三供电电路23被配置为，在电源30为第一目标播放控制设备供电时，为第一播放控制设备11供电。第四供电电路24被配置为，在电源30为第一目标播放控制设备供电时，为第二播放控制设备11供电。
在第一目标供电电路断电时，第二目标供电电路可以为第二目标播放设备供电，第二目标播放控制设备可以继续控制显示装置显示。在停止通过第二目标供电电路为第二目标播放设备供电后，以及在切换第三供电电路23为第一播放控制设备11供电和第四供电电路24为第二播放控制设备12供电的过程中，电源30可以为第一目标播放设备供电，第一目标播放控制设备可以继续控制显示装置显示。这样，可以保证第一播放控制设备11和第二播放控制设备12中的至少一个被供电，从而可以保证显示装置始终处于正常显示状态，提高了播放控 制系统的可靠性。
示例性地，在电源30稳定为第一播放控制设备11供电后，再停止通过第二目标供电电路为第二目标播放控制设备供电。这样，可以避免因电源30未稳定供电，引起第一播放控制设备11或者第二播放控制设备12供电异常，导致显示装置显示异常。
在一些示例中，第一供电电路21断电时，由于第三供电电路23采用第二市电，第二供电电路22采用第一市电，且第一市电与第二市电属于不同的供应商和/或供电站，如果采用第三供电电路23为第一播放控制设备11供电，第一播放控制设备11的供电电压和第二播放控制设备12的供电电压可能不相同。若切换第一播放控制设备11和第二播放控制设备12控制显示装置，可能会出现因第一播放控制设备11和第二播放控制设备12的供电电压差压，导致显示装置显示异常的情况。因此，本公开实施例中，当第一供电电路21和第二供电电路22中的一个断电时，直接切换第三供电电路23为第一播放控制设备11以及第四供电电路24为第二播放控制设备12供电。
可选地，在该实施方式中，电源30还被配置为，在第三供电电路23为第一播放控制设备供电和第四供电电路24为第二播放控制设备供电时，停止为第一播放控制设备11和第二播放控制设备12供电。
由于电源30的电量有限，若一直采用电源30为播放控制设备供电，电源30可能会因为电量不足而无法为播放控制设备供电。因此，在第三供电电路23和第四供电电路24供电时，停止电源30为第一播放控制设备11和第二播放控制设备12供电，可以进一步提高播放控制系统的可靠性。
示例性地，在第三供电电路23和第四供电电路24稳定供电时，再停止通过电源30为第一播放控制设备11和第二播放控制设备12供电。这样，可以避免因第三供电电路23或者第四供电电路24未稳定供电，引起第一播放控制设备11或者第二播放控制设备12供电异常，导致显示装置显示异常。
下面举例说明本实施方式中的供电过程。图4是本公开实施例提供的一种供电时序图。图4中，高电平表示处于供电状态，低电平表示处于断电状态。
如图4所示，在t1时刻之前，通过第一供电电路21为第一播放控制设备11供电，同时通过第二供电电路22为第二播放控制设备12供电。此时，第一播放控制设备11和第二播放控制设备12中的一个控制显示装置显示。
t1时刻，第一供电电路21断电，导致第一供电电路21无法为第一播放控制设备11供电，但是第二供电电路22处于通电状态，第二供电电路22可以为第二播放控制设备12供电，第二播放控制设备12可以控制显示装置正常显示。
t2时刻，通过电源30为第一播放控制设备11供电。此时，电源30供电状态尚未稳定。
t3时刻，电源30处于稳定供电状态，此时停止通过第二供电电路22为第二播放控制设 备12供电，但是电源30可以为第一播放控制设备11供电，第一播放控制设备11可以控制显示装置正常显示。
t4时刻，通过第三供电电路23为第一播放控制设备11供电，同时通过第四供电电路24为第二播放控制设备12供电。此时，第三供电电路23和第四供电电路24供电状态尚未稳定。
t5时刻，第三供电电路23和第四供电电路24可以稳定供电，此时，停止通过电源30供电。可以由第一播放控制设备11和第二播放控制设备12中的一个控制显示装置显示。
可选地，在其他的示例中，t3和t4相同。也即是，可以在停止第二供电电路22供电的同时，通过第三供电电路23和第四供电电路24供电。
在电源30稳定供电后再停止第二供电电路22供电，以及在第三供电电路23和第四供电电路24供电稳定后再停止电源30供电，可以始终保证第一播放控制设备11和第二播放控制设备12中的至少一个被稳定供电，第一播放控制设备11和第二播放控制设备12中的至少一个不会出现因电压波动而导致无法正常工作的现象，提高了播放控制系统的稳定性。
在另一些实施方式中，通过第一供电电路21为第一播放控制设备11供电，同时，通过第二供电电路22为第二播放控制设备12供电。
电源30还被配置为，在第一供电电路21为第一播放控制设备11供电以及第二供电电路22为第二播放控制设备12供电时，为第一播放控制设备11和第二播放控制设备12中的至少一个供电。
例如，电源30只为第一播放控制设备11供电，或者只为第二播放控制设备12供电，或者同时为第一播放控制设备11和第二播放控制设备12供电。
实际场景中，当第一市电或者第二市电中的一个电压不稳定时，需要切换到另一个。
第三供电电路23被配置为，在第一供电电路21断电，且电源30为第一播放控制设备11和第二播放控制设备12中的至少一个供电时，为第一播放控制设备11供电。
第四供电电路24被配置为，在第二供电电路22断电，且电源30为第一播放控制设备11和第二播放控制设备12中的至少一个供电时，为第二播放控制设备12供电。
在第一供电电路21为第一播放控制设备11供电以及第二供电电路22为第二播放控制设备12供电时，通过电源30为第一播放控制设备11和第二播放控制设备12中的至少一个供电，可以使得第一供电电路21和第二供电电路22断电时，以及在切换第三供电电路23为第一播放控制设备11供电以及第四供电电路24为第二播放控制设备12供电的过程中，电源30可以为第一播放控制设备11和第二播放控制设备12中的至少一个供电。这样，可以保证第一播放控制设备11和第二播放控制设备12中的至少一个被供电，从而可以保证显示装置始终处于正常显示状态，提高了播放控制系统的可靠性。
示例性地，在电源30稳定供电后，再停止通过第一供电电路21为第一播放控制设备11供电以及停止通过第二供电电路22为第二播放控制设备供电。这样，可以避免因电源30未 稳定供电，引起第一播放控制设备11或者第二播放控制设备12供电异常，导致显示装置显示异常。
可选地，在该实施方式中，电源30还被配置为，在第三供电电路23为第一播放控制设备11供电和第四供电电路24为第二播放控制设备12为第二播放控制设备12供电时，停止为第一播放控制设备11和第二播放控制设备12供电。
由于电源30的电量有限，若一直采用电源30为播放控制设备供电，电源30可能会因为电量不足而无法为播放控制设备供电。因此，在第三供电电路23和第四供电电路24供电时停止电源30供电，可以进一步提高播放控制系统的可靠性。
下面举例说明本实施方式中的供电过程。图5是本公开实施例提供的一种供电时序图。图5中高电平表示处于供电状态，低电平表示处于断电状态。
如图5所示，在t1时刻之前，通过第一供电电路21为第一播放控制设备11供电，同时通过第二供电电路22为第二播放控制设备12供电。此时，第一播放控制设备11和第二播放控制设备12中的一个控制显示装置显示。
t1时刻，通过电源30为第一播放控制设备11和第二播放控制设备12中的至少一个供电。此时，电源30供电状态尚未稳定。
t2时刻，电源30处于稳定供电状态，此时停止通过第一供电电路21为第一播放控制设备11供电以及停止通过第二供电电路22为第二播放控制设备12供电。但是，电源30可以为第一播放控制设备11和第二播放控制设备12中的至少一个供电，第一播放控制设备11或者第二播放控制设备12可以控制显示装置正常显示。
t3时刻，通过第三供电电路23为第一播放控制设备11供电，同时通过第四供电电路24为第二播放控制设备12供电。此时，第三供电电路23和第四供电电路24供电状态尚未稳定。
t4时刻，第三供电电路23和第四供电电路24可以稳定供电，此时，停止电源30供电。可以由第一播放控制设备11和第二播放控制设备12中的一个控制显示装置显示。
在其他的示例中，t3和t2相同，也即是，可以在断开第一供电电路21和第二供电电路22供电的同时，通过第三供电电路23和第四供电电路24供电。
在电源30稳定后再停止通过第一供电电路21和第二供电电路22供电，以及在第三供电电路23和第四供电电路24稳定供电后再停止电源30供电，可以始终保证第一播放控制设备11和第二播放控制设备12中的至少一个被稳定供电，第一播放控制设备11和第二播放控制设备12中的至少一个不会出现因电压波动而导致无法正常工作的现象。
在又一些实施方式中，通过第三供电电路23为第一播放控制设备11供电，同时，通过第四供电电路24为第二播放控制设备12供电。电源30还被配置为，在第三供电电路23为第一播放控制设备11供电的过程中断电时，为第一播放控制设备11供电；或者，在第四供电电路24为第二播放控制设备12供电的过程中断电时，为第二播放控制设备11供电。
在第三供电电路23断电，切换电源30为第一播放设备21供电期间，由于第四供电电路24为第二播放设备12供电，显示装置仍然可以处于正常显示状态。同样地，在第四供电电路24断电，切换电源30为第二播放设备12供电期间，由于第三供电电路23为第一播放设备11供电，显示装置仍然可以处于正常显示状态。这样，第一播放控制设备11和第二播放控制设备12中的至少一个可以被供电，从而可以保证显示装置始终处于正常显示状态，提高了播放控制系统的可靠性。
可选地，本公开实施例中，播放控制系统还包括检测单元(图中未示出)。
在一些示例中，检测单元可以是电脑或者平板等主机系统。检测单元可以通过检测第一播放控制设备11和第二播放控制设备12是否处于在线状态来判断第一供电电路21、第二供电电路22、第三供电电路23和第四供电电路24是否处于供电状态。
例如，检测单元检测到第一播放控制设备11处于在线状态，则判断第一供电电路21或者第三供电电路23处于供电状态。检测单元检测到第一播放控制设备11处于非在线状态，则判断第一供电电路21或者第三供电电路23处于未供电状态。
在另一些示例中，检测单元可以为电压采集装置。第一供电电路21与第一播放控制设备11之间、第三供电电路23与第一播放控制设备11之间、第二供电电路22与第二播放控制设备12之间以及第四供电电路24与第二播放控制设备12之间分别设置有检测单元。
当检测单元检测到电压有波动时，判断对应的供电电路未稳定供电。当检测单元检测到电压低于第一设定阈值时，判断对应的供电电路处于未供电状态。当检测单元检测电压高于第二设定阈值时，判断对应的供电电路处于供电状态。示例性地，第二设定阈值大于第一设定阈值。第一设定阈值和第二设定阈值由相关技术人员确定。
可选地，本公开实施例中还可以不设置检测单元，当第一供电电路21、第三供电电路23、第二供电电路22、第四供电电路24或者电源30接通设定时间后，确定第一供电电路21、第三供电电路23、第二供电电路22、第四供电电路24处于稳定供电状态。示例性地，设定时间为10s。设定时间由相关技术人员根据实验进行确定。
图6是本公开实施例提供的另一种播放控制系统的结构示意图。如图6所示，播放控制系统还包括插接接头。
以下至少一个位置设置有插接接头，以将插接接头位置前后的部件电连接：第一供电电路21与第一播放控制设备11之间；第二供电电路22与第二播放控制设备12之间；第三供电电路23与第一播放控制设备11之间；第四供电电路24与第二播放控制设备12之间；电源30与第一播放控制设备11之间；电源30与第二播放控制设备12之间。

保护电路中每个二极管51的输入端与第一供电电路21、第二供电电路22、第三供电电路23、第二供电电路24或者电源30连接，每个二极管51的输出端与第一播放控制设备11或者第二播放控制设备12连接。
由于二极管51是单向导电的，电流只能从二极管51的输入端流入输入端，通过设置保护电路，可以避免因第一供电电路21、第二供电电路22、第三供电电路23、第二供电电路24或者电源30的正负极接反，导致损坏第一供电电路21、第二供电电路22、第三供电电路23、第二供电电路24或者电源30，或者损坏第一播放控制设备11和第二播放控制设备12。

图6所示的播放控制系统可以采用图4和图5所示的供电时序进行供电控制。
在一些示例中，当第一供电电路21、第二供电电路22、第三供电电路23和第四供电电路24中的一个断电时，可以采用图4所示的供电时序图进行供电控制。

在另一些示例中，当市电电压不稳定，需要切断市电进行维修；或者需要切换市电时，可以采用图5所示的供电时序图进行供电控制。
图7是本公开实施例提供的一种播放控制系统的供电方法的流程图，应用于图1所示的播放控制系统。参见图7，该方法包括：
