Abstract: A method includes reading a composite video descriptor data structure and a plurality of window descriptor data structures. The composite video descriptor data structure defines a width and height of a composite video frame and each window descriptor data structure defines the starting X and Y coordinate, width and height of each constituent video window to be rendered in the composite video frame. The method further includes determining top and bottom Y coordinates for each constituent video window, as well as determining left and right X coordinates for each constituent video window. The method also includes dividing each constituent video window using the top and bottom Y coordinates to obtain Y-divided sub-windows, dividing each Y-divided sub-window using left and right X coordinates to obtain X and Y divided sub-windows, and storing X, Y coordinates of opposing corners of each X and Y divided sub-window in the storage device.

Abstract translation: 一种方法包括读取复合视频描述符数据结构和多个窗口描述符数据结构。 复合视频描述符数据结构定义复合视频帧的宽度和高度，并且每个窗口描述符数据结构定义要在复合视频帧中呈现的每个构成视频窗口的起始X和Y坐标，宽度和高度。 该方法还包括确定每个构成视频窗口的顶部和底部Y坐标，以及确定每个构成视频窗口的左和右X坐标。 该方法还包括使用顶部和底部Y坐标划分每个构成视频窗口以获得Y分割子窗口，使用左和右X坐标划分每个Y分割子窗口以获得X和Y分割子窗口，以及 将每个X和Y分割子窗口的相对角的X，Y坐标存储在存储装置中。
