模式6：当前页面的布局为：1)左区域为视频B和右区域为视频C，2)左区域为视频C和右区域为视频B。Mode 6: The layout of the current page is: 1) the left area is video B and the right area is video C, 2) the left area is video C and the right area is video B.
针对模式1，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频A的画面，记录该区域的位置，将该画面区域切换到视频A的源(通道1)。For mode 1, the video source allocation method is as follows: if one of the three areas of the current picture selects the picture of video A, record the position of this area, and switch the picture area to the source of video A (channel 1).
针对模式2，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频B的画面，记录该区域的位置，将该画面区域切换到视频B的源(通道1)。For mode 2, the video source allocation method is as follows: if one of the three areas of the current picture is the picture of video B, record the position of this area, and switch the picture area to the source of video B (channel 1).
针对模式3，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频C的画面，记录该区域的位置，将该画面区域切换到视频C的源(通道2)。For mode 3, the video source allocation method is as follows: if one of the three areas of the current picture selects the picture of video C, record the position of this area, and switch this picture area to the source of video C (channel 2).
针对模式4，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频A的画面，记录该区域的位置，将该画面区域位置切换到视频A的源(通道1)；如果当前画面的三种区域中有一种选择的是视频B的画面，记录该区域的位置，如果该区域位置的视频开关是打开状态，则不将该画面区域位置切换到视频B的源。如果该区域位置的视频开关是打开状态，则将该画面区域位置切换到视频B的源(通道2)，此时，由于通道1已被视频A的源占用，视频B的源会通过FC总线将视频B的画面数据发送给视频源C，由视频源C将画面数据通过通道2切换到上述记录的区域的位置。For mode 4, the video source allocation method is as follows: if one of the three areas of the current picture chooses the picture of video A, record the position of this area, and switch the position of this picture area to the source of video A (channel 1); If one of the three areas of the current picture selects the picture of video B, record the position of this area, if the video switch of this area position is on, then do not switch the position of this picture area to the source of video B. If the video switch in this area is on, switch the area of the screen to the source of video B (channel 2). At this time, since channel 1 is already occupied by the source of video A, the source of video B will pass through the FC bus Send the picture data of video B to video source C, and video source C switches the picture data to the position of the above-mentioned recorded area through channel 2.
针对模式5，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频A的画面，记录该区域的位置，将该画面区域位置切换到视频A的源(通道1)；如果当前画面的三种区域中有一种选择的是视频C的画面，记录该区域的位置，则将该画面区域位置切换到视频B的源(通道2)。For mode 5, the video source allocation method is as follows: if one of the three areas of the current picture chooses the picture of video A, record the position of this area, and switch the position of this picture area to the source of video A (channel 1); If one of the three areas of the current picture is selected to be the picture of video C, record the position of this area, then switch the position of this picture area to the source of video B (channel 2).
针对模式6，视频源分配方法如下：如果当前画面的三种区域中有一种选择的是视频B的画面，记录该区域的位置，如果该区域位置的视频开关是打开状态，则将该画面区域位置切换到视频B的源(通道1)，如果该区域位置的视频开关是打开状态，则不将该画面区域位置切换到视频B的源。如果当前画面的三种区域中有一种选择的是视频C的画面，记录该区域的位置，将该画面区域位置切换到视频B的源(通道2)。For mode 6, the video source allocation method is as follows: If one of the three areas of the current screen selects the video B screen, record the location of this area, and if the video switch at the location of the area is on, then the screen area The position is switched to the source of video B (channel 1). If the video switch of the position of this area is on, the position of the area of the screen will not be switched to the source of video B. If one of the three areas of the current picture chooses the picture of video C, record the position of this area, and switch the position of this picture area to the source of video B (channel 2).
