图1为本公开实施例提供的一种显示控制方法的流程图。如图1所示,该方法包括:
步骤S1、接收多个视频源发送的视频流,并获取每个视频流对应的第二优先级参数。
其中,第二优先级参数用于表征其对应的视频流的优先级,该优先级的概念是基于全部视频流而形成的,具体地,优先级高的视频流应得到突出显示,在本公开实施例中,优先级高的视频流可占据显示装置上对应的人眼感 兴趣的位置或者关注度较高的部分。
在一些实施例中,预先配置有各视频流对应的第二优先级参数,可从相应的存储空间中获取第二优先级参数;或者在一些实施例中,在接收到视频流后,接收实时发送的配置指令,根据其中的第二优先级信息确定各视频流对应的第二优先级参数;或者在一些实施例中,基于可扩展的编码格式,各视频流携带有其各自对应的第二优先级参数。
在一些实施例中,该多个视频源可对应多种输入接口以及相应的媒体数据编码格式;例如,在一些实施例中,输入接口包括高清多媒体接口(High Definition Multimedia Interface,简称HDMI)、显示接口(Display Port,简称DP)、数字串行接口(Serial Digital Interface,简称SDI)、以太网输入接口等。
在一些实施例中,第二优先级参数可针对视频源进行配置,由此,特定视频源与相应的优先级之间具有对应关系,其输出的视频流即便发生格式变化等也具有该优先级;或者在一些实施例中,第二优先级参数可针对视频流进行配置,由此,特定编码格式或传输自特定输入接口的视频流与相应的优先级之间具有对应关系。
步骤S2、根据预先为显示装置的各显示区域配置的第一优先级参数和视频流的第二优先级参数,得到各显示区域所对应的视频流。
在步骤S2中,根据第一优先级参数和第二优先级参数可确定显示区域的优先级和视频流的优先级之间的关系,由此建立显示区域和视频流的对应关系。其中,显示装置划分有多个显示区域,每个显示区域均配置有对应的第一优先级参数,第一优先级参数用于表征其对应的显示区域的优先级,该优先级的概念是基于全部显示区域和显示装置而形成的,具体地,优先级高的显示区域对应显示装置上的人眼更感兴趣的位置或者关注度较高的部分。
步骤S3、根据各显示区域所对应的视频流,生成图像数据,并发送给显示装置进行显示。
其中,根据各显示区域所对应的视频流确定对于显示装置整体而言需要显示的帧图像,由此生成图像数据并发送给显示装置进行显示。
在一些实施例中,步骤S3,根据各显示区域所对应的视频流,生成图像数据,并发送给显示装置进行显示的步骤,包括:响应于多个显示区域交叠,在交叠区域,根据其中最高优先级的显示区域所对应的视频流生成图像数据。具体地,不同的显示区域交叠时,具有高优先级的显示区域在进行显示时会覆盖与低优先级的显示区域交叠的部分。可以理解的是,在一些实施例中,各显示区域是互不交叠的。
在一些实施例中,在步骤S2,根据预先为显示装置的各显示区域配置的第一优先级参数和视频流的第二优先级参数,得到各显示区域所对应的视频流的步骤之后,包括:响应于显示区域的数量大于视频流的数量,对于未与视频流建立对应关系的显示区域,根据预设的填充画面确定其对应的图像数据;响应于显示区域的数量小于视频流的数量,输出提示信息,提示信息用于提示存在未显示的视频流。具体地,填充画面可以为单色画面,如黑色画面、红色画面等,或者也可以为测试检查画面,如彩条画面等;提示信息可标识出未得到显示的视频流,在一些实施例中,还包括将提示信息输出至显示装置,以供显示装置根据该提示信息进行显示。
对应于相关技术中的方案,多个视频源对应的画面在屏幕上没有优先级的区分,以具有四个视频源为例,四个视频源对应的画面会在显示装置上以四等分平铺的形式进行显示,对单个或多个视频流无法实现突出显示的效果,无法满足一些场景的使用需求,如广播级监看场景、多人会议场景、多机位舞台场景等。
本公开实施例提供了一种显示控制方法,其可用于接收多个视频源发送的视频流,并获取每个视频流对应的第二优先级参数,根据显示装置的各显示区域的第一优先级参数和视频流的第二优先级参数,得到各显示区域所对 应的视频流,根据各显示区域所对应的视频流,生成图像数据,并发送给显示装置进行显示,由此,基于显示装置的各显示区域的优先级和视频流的优先级建立显示区域和视频流的对应关系,实现显示装置在多视频源下的突出显示。
图2为本公开实施例提供的另一种显示控制方法的流程图。如图2所示,该方法为基于图1所示方法的一种具体化可选实施方案。具体地,该方法不仅包括步骤S1至步骤S3,还包括步骤S01和步骤S02。下面仅针对步骤S01和步骤S02进行详细描述。
步骤S01、响应于第一配置指令,根据第一配置指令中的位置信息确定显示区域所在的位置以及显示分辨率,根据第一配置指令中的第一优先级信息确定显示区域对应的第一优先级参数。
步骤S02、响应于第二配置指令,根据第二配置指令中的第二优先级信息确定视频流对应的第二优先级参数。
在一些实施例中,显示区域可为规则图形,如矩形等。以显示区域为矩形为例,第一配置指令中的位置信息可包括两个特定位置的坐标,如矩形对角线所连接的顶点坐标等,基于该两个位置的坐标可确定显示区域的位置及显示分辨率;若显示装置的显示分辨率为M*N,则显示区域对应的最小显示分辨率为M/x*N/x,x为可随显示装置的显示分辨率变化的参数,例如,在一些实施例中,显示屏幕的显示分辨率为全高清(Full High Definition,简称FHD)分辨率(1920*1080或者2048*1080)时,x可取100,显示屏幕的显示分辨率为4K分辨率(3840*2160或者4096*2160)时,x可取200,当显示屏幕的显示分辨率为8K分辨率(7680*4320或者8192*4320)时,x可取400,对于M或者N和x不能整除的情况,对其结果可通过向上取整或向下取整或四舍五入取整的方式进行处理以得到该最小显示分辨率。
在一些实施例中,使用者可基于交互界面和交互装置实现对显示区域的 配置,交互界面可为图像化界面,交互装置可基于按钮输入控制、触摸输入控制、键鼠输入控制等;在一些实施例中,使用者每完成对一个显示区域的配置,或者每完成对一个显示区域原有的配置信息的修改,会下发一次第一配置指令,或者在一些实施例中,使用者完成对全部显示区域的配置或对全部显示区域原有的配置信息的修改后,下发第一配置指令。相应地,在一些实施例中,使用者每完成对一个视频流的配置,或者每完成对一个视频流原有的配置信息的修改,会下发一次第二配置指令,或者在一些实施例中,使用者完成对全部视频流的配置或对全部视频流原有的配置信息的修改后,下发第二配置指令。
需要说明的是,本公开实施例对步骤S1至步骤S3、步骤S01至步骤S02的执行顺序不做限制。即步骤S01至步骤S02可在步骤S1至步骤S3之前执行,具体地,其对应在一些实施例中,预先完成对显示区域和视频流的配置的情况;或者,步骤S01至步骤S02可在步骤S1至步骤S3之后执行,或者,步骤S01至步骤S02可与步骤S1至步骤S3穿插执行,具体地,其对应在一些实施例中,在已进行视频流的显示或者准备进行视频流的显示时,使用者实时配置的情况。
图3为本公开实施例中步骤S01的一种具体实施方法流程图。如图3所示,在步骤S01中,根据第一配置指令中的位置信息确定显示区域所在的位置以及显示分辨率的步骤之后,还包括:步骤S011。
步骤S011、对于确定出的显示区域,至少对其边缘部分进行标记。
其中,每个显示区域对应的标记类型不同,标记类型包括颜色和亮度中的至少一者,由此,对每个显示区域通过不同的颜色和/或亮度进行标记;在一些实施例中,对显示区域的边缘部分进行标记,或者在一些实施例中,对显示区域的边缘部分和内部均进行标记。
以及,在一些实施例中,如图3所示,在步骤S01中,根据第一配置指 令中的第一优先级信息确定显示区域对应的第一优先级参数的步骤之后,还包括:步骤S012。
步骤S012、对于确定出的显示区域,在其内部根据其第一优先级参数对其进行标记。
其中,可通过相应的文本或字符标识在显示区域内部对其优先级进行标记。
在一些实施例中,通过随机选择的方式确定标记内容并进行标记;或者在一些实施例中,可根据使用者预先设置的标记方式确定标记内容并进行标记;或者在一些实施例中,根据使用者当前选择的标记方式确定标记内容并进行标记。
以及,在步骤S011和/或步骤S012之后,还包括:步骤S013。
步骤S013、在显示区域显示其对应的标记内容。
其中,标记内容即上述基于颜色和/或亮度的标记结果,以及对优先级的标记结果。
图4为本公开实施例提供的一种显示区域的示意图。如图4所示,其示例性地示出了一种显示区域的标记方式。其中,以不同的填充图形标识不同的显示区域,可以理解的是,前述的不同的颜色和/或亮度同样可以标识不同的显示区域;以H1、H2、H3、H4、H5标识不同显示区域的优先级;在(a)中,其示出了多个显示区域无交叠部分的情况,不同显示区域具有不同的优先级;在(b)中,其示出了多个显示区域出现交叠的情况,并且不同显示区域可具有相同的优先级。
在一些实施例中,在步骤S2,根据预先为显示装置的各显示区域配置的第一优先级参数和视频流的第二优先级参数,得到各显示区域所对应的视频流的步骤之后,还包括:取消在每个显示区域显示其对应的标记内容。由此,在完成对显示区域的优先级配置,并确定各显示区域对应的视频流后, 显示区域不再显示特定颜色、特定亮度以及标识等标记内容,而是准备显示对应的视频流的图像数据。
图5为本公开实施例中步骤S3的一种具体实施方法流程图。如图5所示,步骤S3,根据各显示区域所对应的视频流,生成图像数据,并发送给显示装置进行显示的步骤,包括:步骤S301。
步骤S301、根据各显示区域的显示分辨率,对各显示区域所对应的视频流进行变换处理。
其中,根据各显示区域的显示分辨率对视频流进行变换处理可包括上采样和下采样。具体地,因为使用者绘制确定的显示区域的显示分辨率,和视频流的原始分辨率不一定相同,则视频流需要根据对应的显示区域进行分辨率的适配。
其中,以显示区域是矩形为例,将显示区域和视频流对应的图像画面在行方向上的一边作为长,在列方向上的一边作为宽。在一些实施例中,上述的显示分辨率和原始分辨率成一定比例关系,即显示区域的长M比上视频流的图像画面的长m等于比值e,显示区域的宽N比上视频流的图像画面的宽n也为比值e,则可将视频流的分辨率基于比值e进行放大或者缩小,其长宽比例保持不变,其对应的图像画面不会变形。或者在一些实施例中,显示分辨率和原始分辨率不成比例关系,即显示区域的长M比上视频流的图像画面的长m等于比值e1,显示区域的宽N比上视频流的图像画面的宽n等于比值e2,且e1和e2不相等,又分为以下几种情况:如果e1>e2>1,则可对视频流按照比值e2进行长和宽的拉伸,对应放大、上采样过程;如果e2>e1>1,则可对视频流按照比值e1进行长和宽的拉伸;如果e1<e2<1,可对视频流按照比值e2进行长和宽的压缩,对应缩小、下采样过程;如果e2<e1<1,可对视频流按照比值e1进行长和宽的压缩;如果e1<1<e2,可对视频流按照比值e1进行长和宽的压缩;如果e2<1<e1,可对视频流按照比值e2 进行长和宽的压缩;其中,视频流的分辨率按照等比例的拉伸或者压缩,其对应的图像画面的分辨率发生变化但是画面长宽比例不会变化;以及,因为显示区域和视频流的分辨率不同,视频流经过拉伸或者压缩后,只能保证其长和宽有一边和显示区域的长或宽一致,另一边则会小于显示区域的长或宽,则此时需保证视频流的图像数据在不一致的一边所对应的方向上居中显示。

步骤S4、根据第一优先级参数对各显示区域进行检测,并在检测不通过时输出告警信息。
其中,对于任意两个显示区域,检测高优先级的显示区域的显示分辨率是否大于或等于低优先级的显示区域的显示分辨率,和/或,检测高优先级的显示区域对应的第一距离是否小于或等于低优先级的显示区域对应的第二距离,第一距离为高优先级的显示区域内的第一预设点与显示装置上的第二预设点之间的距离,第二距离为低优先级的显示区域内的第二预设点与第二预设点之间的距离。具体地,基于人眼感知特性,为实现突出显示,需保证高优先级的显示区域占用显示装置的面积更大,和/或,所处的位置更靠近人眼感兴趣的位置;在一些实施例中,显示区域内的第一预设点为显示区域的中心点,显示装置上的第二预设点为显示装置的中心点。
