图4是本申请实施例四提供的一种显示系统的结构示意图。
具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地 描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
参见图1,是本申请实施例一提供的一种多屏设备的同步显示方法的流程示意图,上述方法应用于N个显示屏构成的显示系统中,该显示系统可以为异形屏。其中,N为大于1的整数,也就是上述方法应用在至少两个显示屏构成的显示系统中,且所有的显示屏处于同一个局域网内,使得显示屏之间的通信在局域网内完成,从而降低延时至20ms。如图2所示,该同步显示方法可以包括以下步骤:
步骤S101,从N块显示屏中选取任一显示屏作为服务端,其他显示屏作为受控端,检测所有受控端是否均已上线。
本申请中,方法在运行时均可以任一选取一个显示屏作为服务端,其他的显示屏则作为受控端,服务端与受控端在局域网内进行通信,受控端向服务端发送状态等信息,并且能够从服务端下载相应的数据,即受控端受控于服务端。在一实施方式中,方法运行之前,根据需求可以规定N块显示屏中某一块显示器作为服务端,其他显示屏作为受控端,方法在运行时选取服务端即为选取已事先规定的服务端。
每个显示屏均可以通过唯一的身份标识号(Identity document,ID)表征,以此可以区分不同的显示器。
受控端在上线后可以向服务端发送上线信息,以提示服务端其已上线,使得服务端能够检测到所有受控端的上线状态,在所有受控端均发送上线信息时,确定所有受控端均已上线。
步骤S102,若检测到所有受控端均已上线,则在服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据。
本申请中,其他与显示系统连接的设备用于向显示系统发送视频文件等数据,在确定服务端后,其他设备是将数据发送给服务端的。服务端实时监测是否收到其他设备发送的数据,若接收到其他设备发送的数据,则确定检测到当前时刻存在待显示数据。
触发可以是指让受控端执行下载动作,具体的操作可以是指服务端向受控端发送指令。受控端下载数据是从服务端中下载,也即是从待显示数据中下载。
待显示数据可以是指已经进行数据分割的子数据,其中,每个显示屏即受控端对应有自己的子数据,可以采用与显示屏ID匹配的方式得到对应的子数据。该第二目标数据为受控端所要显示的数据,服务端显示的数据为第一目标数据,第一目标数据和第二目标数据均为待显示数据中的数据。例如,针对一个完整的图像,为了在不同的显示屏中显示,事先根据多个显示屏构成的显示系统的形状将图像分割,每个显示屏对应一块图像,在显示时仅展示其对应的图像,从而显示系统所有显示屏均显示后构成完整的图像。
可选的是,在服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据包括:
在服务端检测到当前时刻存在待显示数据时,服务端向所有受控端发送下载指令;
每个受控端从待显示数据中下载与对应的第二目标数据。
其中,服务端在检测到存在待显示数据时,向受控端发送下载指令,受控端接收到下载指令后,从服务端的待显示数据中下载对应的数据。
步骤S103,在所有受控端均下载完成后,触发服务端准备播放待显示数据中的第一目标数据,并触发所有受控端准备播放对应的第二目标数据,检测服务端和所有受控端是否准备完成。
本申请中,第一目标数据已经在服务端中,因此服务端无需下载该第一目标数据。准备播放可以是指解压数据、加载数据等用于播放前的准备工作,在准备工作完整后显示屏可以进入播放。
在所有的受控端均下载完成后才开始准备播放,能够避免受控端出现下载失败等情况时重新执行上述步骤导致的资源浪费。
可选的是,在所有受控端均下载完成后,触发服务端准备播放待显示数据中的第一目标数据,并触发所有受控端准备播放对应的第二目标数据包括:
所有受控端向服务端发送下载完成指令;
服务端在接收到所有受控端发送的下载完成指令后,服务端启动对应播放器加载待显示数据中的第一目标数据,并向所有受控端发送准备播放指令;
所有受控端在接收到准备播放指令后,启动对应播放器加载对应的第二目标数据。
其中,下载完成后所有的受控端均向服务端发送下载完成指令,随后服务端启动其播放器加载第一目标数据,并向受控端发送准备播放指令,使得受控端启动其播放器加载对应的第二目标数据,从而完成播放前的准备工作。
可选的是,检测服务端和所有受控端是否准备完成包括:
在所有受控端均加载完成对应的第二目标数据后,向服务端发送加载完成信号;
若服务端接收到所有受控端发送的加载完成信号,且检测到已加载完成第一目标数据,则确定服务端和所有受控端均准备完成,否则,确定服务端和所有受控端未均准备完成。
其中,受控端加载完成后向服务端发送加载完成信号,服务端接收到所有受控端发送的加载完成信号即可确定所有受控端准备完成,若服务端也已加载完成,则所有的显示屏都完成了播放前的准备工作,随后才能够进入播放。
步骤S104,在检测到服务端和所有受控端均准备完成后,启动所有显示屏进行同步播放。
本申请中,服务端和所有受控端均准备完成后,启动播放,所有的显示屏同步播放。例如,服务端下发定时播放指令,所有受控端接收到该定时播放指令后,在指定时间,服务端和所有受控端同时播放,实现同步。
本申请实施例应用于N块显示屏,N块显示屏处于同一局域网内,从N块显示屏中选取任一显示屏作为服务端,其他显示屏作为受控端,在检测到受控端均已上线,且服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据,在所有受控端均下载完成后,触发服务端准备播放待显示数据中的第一目标数据,并触发所有受控端准备播放对应的第二目标数据,在检测到服务端和受控端均准备完成后,启动所有显示屏进行同步播放,实现多个显示屏的联动控制器,多个显示屏处在同一局域网内,能够有效地降低显示屏之间的通信延时,采用统一的控制条件使得显示屏能够同步显示,提高了联动控制的精准度。
参见图2,是本申请实施例二提供的一种多屏设备的同步显示方法的流程示意图。如图2所示,该同步显示方法可以包括以下步骤:
步骤S201,从N块显示屏中选取任一显示屏作为服务端,其他显示屏作为受控端,检测所有受控端是否均已上线。
步骤S202,若检测到所有受控端均已上线,则在服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据。
步骤S203,在所有受控端均下载完成后,触发服务端准备播放待显示数据中的第一目标数据,并触发所有受控端准备播放对应的第二目标数据,检测服务端和所有受控端是否准备完成。
步骤S204,在检测到服务端和所有受控端均准备完成后,启动所有显示屏进行同步播放。
其中,上述步骤S201至步骤S204与上述实施例一种步骤S101至步骤S104的内容相同,可参考上述步骤S101至步骤S104的描述,在此不再赘述。
步骤S205,每间隔预设时长获取服务端的第一播放进度,并将第一播放进度发送给所有受控端。
本申请中,间隔一定时间检测播放进度,尤其是服务端的播放进度与受控端的播放进度。在一实施方式中,间隔的预设时长为300ms。
步骤S206,针对任一受控端,检测受控端的第二播放进度与第一播放进度的差异。
本申请中,服务端向受控端发送自己的第一播放进度,受控端将自己的第二播放进度与第一播放进度进行比较,得到播放进度的差异,并受控端根据差异执行后续的修正工作。
在一实施方式中,受控端将自己的第二播放进度发送给服务端,由服务端进行差异检测,并根据差异执行后续的修正工作。
步骤S207,若差异大于差异阈值,则修正服务端与受控端的播放进度差异小于差异阈值。
本申请中,差异较大时需要对播放进度进行修正,以保证显示屏的同步。在一实施方式中,差异阈值可以为200ms,以满足人眼对视屏同步的观测要求。
差异可以是指第一播放进度大于第二播放进度,也可以是指第一播放进度小于第二播放进度。
修正可以是指使用一个播放进度替换当前播放进度,还可以是指自动向前或者向后条件一定播放进度,达到修正的目的。
可选的是,修正服务端与受控端的播放进度差异小于差异阈值包括:
使用第一播放进度更新受控端的播放进度。
其中,采用第一播放进度更新受控端的播放进度,实现修正,修正后的差异基本达到通信的延时时间,由于局域网内的通信延时时间远小于差异阈值,因此,可以满足修正条件。
可选的是,修正服务端与受控端的播放进度差异小于差异阈值包括:
若第一播放进度小于第二播放进度,则检测所有受控端与服务端的播放进度的差异;
若所有受控端中第一播放进度小于第二播放进度的受控端的数量大于数量阈值,则使用第一播放进度小于第二播放进度的受控端中差异最大的第二播放进度,并使用最大的第二播放进度更新服务端的播放进度。
其中,针对第一播放进度小于第二播放进度的情况,为了避免出现跳过播放帧,判断第二播放进度小于第一播放进度的受控端的个数,如果个数大于数量阈值,则说明大部分的受控端播放进度较慢,因此,可以修正服务端的播放进度,具体可以采用播放进度较慢的受控端中播放进度最靠前的为目标播放进度即最大的第二播放进度,并以目标播放进度更新服务端的播放进度。
本申请实施例应用于N块显示屏,N块显示屏处于同一局域网内,从N块显示屏中选取任一显示屏作为服务端,其他显示屏作为受控端,在检测到受控端均已上线,且服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据,在所有受控端均下载完成后,触发服务端准备播放待显示数据中的第一目标数据,并触发所有受控端准备播放对应的第二目标数据,在检测到服务端和受控端均准备完成后,启动所有显示屏进行同步播放,实时获取播放进度,并对播放进度进行修正,提高显示屏的同步精度。
对应于上文实施例的同步显示方法,图3示出了本申请实施例三提供的多屏设备的同步显示装置的结构框图,上述同步显示装置应用于N个显示屏构成的显示系统中,该显示系统可以为异形屏。其中,N为大于1的整数,也就是上述方法应用在至少两个显示屏构成的显示系统中,且所有的显示屏处于同一个局域网内,使得显示屏之间的通信在局域网内完成,从而降低延时至20ms。为了便于说明,仅示出了与本申请实施例相关的部分。

视频下载模块32,用于若检测到所有受控端均已上线,则在服务端检测到当前时刻存在待显示数据时,触发所有受控端从待显示数据中下载与其受控端对应的第二目标数据;

可选的是,上述播放准备模块33包括:
第一指令发送单元,用于所有受控端向服务端发送下载完成指令;
