具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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。
本申请实施例，服务器将多路第一视频信号合并为一路第二视频信号，在一路第二视频信号中同时显示多个第一视频信号的画面，终端设备通过对第一视频信号的画面的选择操作，显示相应的第一视频信号的画面，使得用户在观看视频的同时可以轻松操作以选择自己感兴趣的节目画面进行观看。
图1是本申请实施例提供的一种视频画面切换方法，适用于终端设备，如电视，电脑等，该方法包括以下步骤S101-S103。
在步骤S101中，显示来自服务器的一路第二视频信号，所述第二视频信号由多路第一视频信号合并而成，包括所述多路第一视频信号的画面。
第一视频信号可以是来自于直播节目的直播视频信号，或者是录播视频信号。将多路第一视频信号做为输入信号合并成一路第二视频信号，例如，直播节目中同时从多个摄像机位传回的多个角度的视频画面，或者是其他节目中多个摄像机从不同角度录制的视频画面。
在步骤S102中，当检测到针对第一视频信号的画面的选择操作时，确定所述选择操作的坐标信息并发送至所述服务器。
每一路第一视频信号的画面在一路第二视频信号中具有固定的显示位置，显示位置是指第一视频信号的画面在第二视频信号的画面中的相对位置。当用户对感兴趣的第一视频信号的画面进行选择操作时，可确定该被选择的第一视频信号的画面在一路第二视频信号中的显示位置(即坐标信息)，服务器根据该坐标信息可实现与该坐标信息匹配的第一视频信号的画面的显示。
第一视频信号的画面在一路第二视频信号中的显示位置与第一视频信号的尺寸和第二视频信号的预设分辨率有关，尺寸是第一视频信号的画面在第二视频信号的画面中的大小。
首先根据多路第一视频信号的路数和第二视频信号的预设分辨率，确定每路第一视频信号的尺寸。可以根据预设分辨率和路数将第二视频信号画面进行平分，平均分配给每一路第一视频信号；也可以根据各路第一视频信号的画面显示时间或者重要程度，给显示时间更长或者更重要的画面分配更大的尺寸，以利于导播观察该画面是否正常，例如针对被设置在面向会场、广场或者体育场馆中央的摄像机位所拍摄的画面的第一视频信号，可以设置较大尺寸以利于导播监控这一路第一视频信号是否正常。
例如，第二视频信号的预设分辨率为1080×720，共有四路第一视频信号，那么，可以将预设分辨率平均分配给四路第一视频信号，每一路视输入信号的尺寸为540×360，也可以将相对重要的一路第一视频信号的尺寸设置为1080×360，其他三路第一视频信号为360×360。上述各路第一视频信号的尺寸划分方式仅用于示例性说明，不构成对本申请保护范围的限制。
根据确定的各路第一视频信号的尺寸，再进一步确定各路第一视频信号 的画面的显示位置，可以将各路第一视频信号的画面全部平铺在第二视频信号的画面中，并以第一视频信号画面的左上角的坐标来表示该路第一视频信号的显示位置。
例如，以第二视频信号的画面的左上角为原点，原点坐标为(0，0)，第二视频信号预设分辨率为1080×720，四路第一视频信号的尺寸都是540×360，将第二视频信号的画面平均划分为左上、右上、左下和右下四个显示区域。第一路第一视频信号显示在左上显示区域，其画面的左上角的坐标为(0，0)；第二路第一视频信号显示在右上显示区域，其画面的左上角的坐标为(540，0)；第三路第一视频信号显示在左下显示区域，其画面的左上角的坐标为(0，360)；第四路第一视频信号显示在右下显示区域，其画面的左上角的坐标为(540，360)。
当用户选择左上区域时，则相应的将与第一路第一视频信号画面的左上角的坐标为(0，0)发送至服务器；当用户选择右上区域时，则相应的将与第二路第一视频信号画面的左上角的坐标为(540，0)发送至服务器；当用户选择左下区域时，则相应的将与第三路第一视频信号画面的左上角的坐标为(0，360)发送至服务器；当用户选择右下区域时，则相应的将与第四路第一视频信号画面的左上角的坐标为(540，360)发送至服务器，服务器根据接收的坐标位置信息，将与坐标位置信息相匹配的第一视频信号返回至终端设备予以显示。
或者，终端设备获取用户点击的位置坐标，将位置坐标发送到服务器，由服务器根据位置坐标确定用户点击选择的区域，然后确定匹配到的第一视频信号并返回。
例如，以第二视频信号的画面的左上角为原点，原点坐标为(0，0)，第二视频信号预设分辨率为1080×768，四路第一视频信号的尺寸都是540×384，将第二视频信号的画面平均划分为左上、右上、左下和右下四个显示区域。第一路第一视频信号显示在左上显示区域，其画面的左上角的坐标为(0，0)；第二路第一视频信号显示在右上显示区域，其画面的左上角的坐标为(540，0)；第三路第一视频信号显示在左下显示区域，其画面的 左上角的坐标为(0，384)；第四路第一视频信号显示在右下显示区域，其画面的左上角的坐标为(540，384)。
用户随机点击的位置坐标为(560，390)，终端设备获取该坐标并将其发送至服务器，服务器根据位置坐标(560，390)确定用户点击选择的区域为右下区域，此时确定与右下区域匹配的第四路第一视频信号并返回。
在步骤S103中，显示所述服务器返回的与所述坐标信息匹配的第一视频信号的画面。
根据确定的被选择的第一视频信号画面的坐标信息，获取与该坐标信息相匹配的第一视频信号，并将该第一视频信号的画面予以显示。
本实施例中，将多路第一视频信号合并为一路第二视频信号，使得用户可以同时观看多种视频内容，并且用户在观看的同时，可对感兴趣的视频内容进行点击播放，实现了视频画面的自由切换，提高了用户体验。
在一个实施例中，如图2所示，该视频画面切换方法进一步包括以下步骤S104-S105。
在步骤S104中，当检测到针对与所述坐标信息匹配的第一视频信号的码流切换操作时，发送切换的码流信息至所述服务器。
码流(Data Rate)是视频文件在单位时间内使用的数据流量，在同样分辨率下，视频文件码流越大，压缩比越小，画面质量就越好。例如，第一视频信号画面的码流分为标清、高清、超清三个档次，用户可根据观看需求选择相应档次的码流，当要求视频画面有较高的分辨率及清晰度时，可选择高档次的码流，当对视频画面的流畅性有较高要求时，可选择低档次码流。
在步骤S105中，将与所述坐标信息匹配的第一视频信号切换至所述服务器返回的与所述码流信息对应的码流进行显示。
根据用户选择的码流档次，显示与该选择的码流档次相匹配的视频画面。
本实施例中，可根据用户对画面质量的不同需求，选择满足用户需要的视频画面进行显示，例如，当用户想要观看高清画面时，可选择具有较高码 流的视频画面予以显示，当用户想要保证视频画面的流畅性，可选择具有较低码流的视频画面予以显示，进一步的提升用户体验。
在一个实施例中，如图3所示，该视频画面切换方法进一步包括以下步骤S106-S107。
在步骤S106中，当检测到切换第二视频信号的操作时，发送第二视频信号切换信息至服务器。
多路第一视频信号合并为一路第二视频信号，在一路第二视频信号中同时显示多个第一视频信号的画面，当第一视频信号多于一路第二视频信号可安排的最大限制时，则存在多路第二视频信号，用户在其中一路第二视频信号中没有感兴趣的内容时，可通过翻页操作进入另一路第二视频信号。
例如，一路第二视频信号最多可显示四路第一视频信号，而第一视频信号的总量为十二路，此时在一路第二视频信号中难以显示全部的第一视频信号，因此就存在多路第二视频信号，即设置共三路第二视频信号可实现十二路第一视频信号的显示，例如，用第一路第二视频信号显示1-4路第一视频信号，用第二路第二视频信号显示4-8路第一视频信号，用第三路第二视频信号显示9-12路第一视频信号。当前显示的为第一路第二视频信号时，而用户感兴趣的视频为第8路第一视频信号时，用户只需进行翻页操作，即可进入第二路第二视频信号，然后选择感兴趣的视频画面进行观看。
在步骤S107中，将所述显示的第二视频信号切换为来自所述服务器的另一路第二视频信号。
当用户对当前第二视频信号中的第一视频信号均不感兴趣时，通过翻页进入下一路第二视频信号，当前显示的第二视频信号则切换为服务器中的另一路第二视频信号，用户在该另一路第二视频信号中选取感兴趣的第一视频信号进行观看，若用户在该路第二视频信号中仍然没有找到感兴趣的视频，可再次进行翻页，直到找到自己感兴趣的视频画面。
本实施例中，通过设置多路第二视频信号可实现更过路数的第一视频信号的画面的显示，用户可通过翻页操作，选取自己感兴趣的视频画面，增加 了用户的可选择性，且操作方便。
在一个实施例中，如图4所示，该视频画面切换方法进一步包括以下步骤S108-S109。
在步骤S108中，当检测到针对与所述坐标信息匹配的第一视频信号的画面的图像处理操作时，发送对应的编码参数至所述服务器。
用户选择感兴趣的第一视频信号的画面进行观看时，还可对直播画面进行图像处理操作，例如图像锐化、去噪、加logo等，用户可根据观看需要选择一种或多种图像处理操作对待观看的画面进行优化处理，根据用户选择的图像处理操作，将与该选择的图像处理操作对应的编码参数发送至服务器。
在步骤S109中，将与所述坐标信息匹配的第一视频信号切换至所述服务器返回的根据所述编码参数调整后的码流进行显示。
由服务器根据选择的图像处理操作对应的编码参数对第一视频信号的画面的码流进行调整并返回终端设备，然后终端设备将第一视频信号切换至调整后的码流予以显示，以此获得符合用户观看需求的视频画面。
本实施例中，用户可根据个人观看需求对待观看的视频画面进行处理，进一步的提升了用户体验，选择自由性高。
在一个实施例中，如图5所示，所述步骤S103可进一步实施为以下步骤S1031。
在步骤S1031中，获取与所述坐标信息匹配的第一视频信号的最低码率的码流进行显示。
为了用户的直播体验，保证直播视频的流畅性，优先选择码率最低的那个档次的码流进行显示。
