[0025] 下面结合附图和实施例对本发明的视频会议中显示视频窗口的方法作详细描述。 The drawings and embodiment of a method of displaying a video window video conference according to the present invention described in detail [0025] below in conjunction.

[0026] 参见图1所示,本发明的视频会议中显示视频窗口的方法,包括以下步骤: [0026] Referring to FIG. 1, the video window display method according to the present invention, a video conference, comprising the steps of:

[0027] 步骤101 :获取视频会议中打开的视频窗口数N,即确定显示装置的显示视频窗口数。 [0027] Step 101: acquiring the video conference video window opening number N, i.e., the video display device determines the number of display windows.

[0028] 步骤102 :根据所述N值生成各个视频窗口的显示模板;即设定各个视频窗口在显示装置上的显示分辨率及其视角等。 [0028] Step 102: the value of each template to generate a display based on the video window N; i.e. setting respective display resolution and viewing angle video window on the display device and the like.

[0029] 步骤103 :将所述视频窗口依据所述显示模板在显示装置上进行显示。 [0029] Step 103: the video display window according to the template displayed on the display device.

[0030] 实际应用中,用户可以随时打开或关闭与会人的视频窗口来控制N的个数。 [0030] In practice, the user can turn on or off at any participant's video window to control the number of N. 对于步骤101,具体地,可以在会议发起后,通过会议服务器MCU控制打开的视频窗口数来获取有视频数据传输的与会人员(每个与会成员都配有视频装置),从而获取打开的视频窗口数N。 For Step 101, specifically, after initiating the meeting, the number of MCU conference server to acquire video window opens participants video data transmission control (participating members each equipped with a video device), thereby acquiring video window opening number N.

[0031] 对于步骤102,主要是设置各个视频窗口在显示装置上的进行显示时的模板,即设置显示分辨率及其视角等,如图2所示,包括如下步骤: [0031] For Step 102, the main video window is provided each template when displayed on a display device, i.e., set the display resolution and viewing angle, etc., shown in Figure 2 comprising the steps of:

[0032] 步骤201 :根据所述N值设置基准窗口;其中,基准窗口是作为参考的视频窗口,其它视频窗口相对基准窗口的位置是固定的。 [0032] Step 201: The reference value is set to the window N; wherein the window is a reference as a reference video window, the video window relative to the reference position of the other window is fixed. 具体地,设置基准窗口位置可以采用以下方法: 首先判断N是否为奇数,若是,则将第(N+1) /2个视频窗口设为基准窗口,若否,则将第N/2 和第N/2+1个视频窗口设为基准窗口。 Specifically, the reference position of the window can be provided using the following procedure: first determined whether N is an odd number, and if yes, the first (N + 1) / 2 video windows as a reference window, and if not, then the second N / 2 and N / 2 + 1 video windows as a reference window.

[0033] 步骤202 :依据所述基准窗口及所述N值设置所述视频窗口的显示布局;具体地, 可以包括以下步骤: [0033] Step 202: according to the reference display window and the layout of the video window value N; in particular, may comprise the steps of:

[0034] (a)获取显示区域的显示分辨率;其中,显示区域是视频窗口在显示装置上所占据的区域,具体地,通过首先获取显示装置的分辨率,然后再减去预留位置的分辨率。 [0034] (a) acquiring a display resolution of a display area; wherein the video window display area is an area occupied on the display device, in particular, by obtaining the first resolution of the display device, then subtract placeholder resolution. [0035] (b)依据基准窗口、N值预设各个视频窗口之间的拼接角度;具体地,在设置基准窗口后,在显示区域中间显示的视频窗口的位置已经确定,根据N值情况,用户可以预设各个视频窗口之间的拼接角度,从而可以使得视频窗口以一定的弧度拼接排列。 [0035] (b) based on the reference window, the value of N predetermined angles between the respective video mosaic windows; Specifically, after the reference window, the video window in the display position of the middle area of ​​the display has been determined, according to the N value, splice user can preset an angle between the respective video window, the video window that can be a constant curvature mosaics.

[0036] (c)根据所述拼接角度计算并分配显示区域的显示分辨率;具体地,根据设定的拼接角度计算出各个视频窗口的坐标显示范围,得到视频窗口的显示布局。 [0036] (c) is calculated and assigned according to the splicing angle of the display resolution of the display region; specifically, each video window is calculated according to the splicing angle setting range display coordinates, to obtain the display layout of the video window.

[0037] 步骤203 :根据所述显示布局生成各个视频窗口的显示模板;具体地,当N是奇数时,将第(N+l)/2个视频窗口(基准窗口)设置在显示区域的中间位置,然后按预设角度拼接其它视频窗口,当N是偶数时,,将第N/2和第N/2+1个视频窗口(基准窗口)拼接的中点设置在显示区域的中间位置,然后按预设角度拼接其它视频窗口;每个显示模板对应一个视频窗口,实际应用中,将视频数据发往相应的视频窗口的显示模板进行显示。 [0037] Step 203: according to the display layout template generating respective video display window; Specifically, when N is an odd number, the first (N + l) / 2 video window (reference window) is provided in the middle display region position, and then press a predetermined angle other video mosaic window when N is an even number,, the first N / 2 and the intermediate position of the N / 2 + 1 video window (reference window) is provided spliced ​​midpoint of the display area, then spliced ​​by a predetermined angle other video windows; each template corresponding to a video display window, the practical application, the video data to the display template corresponding video display window.

[0038] 参见图3所示,假设在一个4个人的视频会议中(实际应用中用户可以根据需要设定显示装置的显示人数),获取到视频窗口数N = 4,其中,①、②、③、④分别为4个视频窗口的编号,首先获取显示装置的屏幕横向分辨率为X,纵向分辨率为Y,需要说明的是,用户可以对显示装置的分辨率进行自由设置。 [0038] Referring to Figure 3, suppose that four people in a video conference (number of users in practical use can be displayed according to the display device needs to be set), the number of video windows to obtain N = 4, wherein, ①, ②, ③, ④ are four video window number acquired first lateral screen resolution of the display device X, the vertical resolution of Y, be noted that the user can freely set the resolution of the display device.

[0039] 假设显示装置在显示区域的两边需要预留出ρ的宽度,则显示区域的横向显示分辨率为X-2p,设两个基准窗口视频窗口的宽度为X,则 [0039] assumed that the display device in the display area on both sides of the need to reserve the width of ρ, the display region of the display resolution of a lateral X-2p, provided two reference video window width of the window is X, then

[0040] X-2p = 2x(l+cos α ) [0040] X-2p = 2x (l + cos α)

[0041] 通过上述公式可以求得x,由于视频窗口的长高比例一般为4 : 3、16 : 9的规格, 下面选取4 : 3的为例,则可以计算得到视频窗口高度为3x/4,在得到视频窗口的长、高以及拼接角度之后,即可根据这些数据来计算每个视频窗口的显示范围。 [0041] x can be obtained by the above equation, since a high proportion of long video window is generally 4: 9 specification, the following select 4: 3 and 16: 3 as an example, it is possible to calculate the height of the video window 3x / 4 , after obtaining length and height of the video window as well as the angle of stitching, the display range can be calculated for each video window based on these data.

[0042] 然后将视频显示区域依据每个视频窗口的显示范围进行分配显示分辨率,优选地,采用黄金分割原则进行分配,将基准窗口的中心点设置在显示装置的中线上,即视频窗口的中心点的纵坐标在整个显示装置的屏幕纵坐标的黄金点分割点上(离屏幕最下方的高度为0. 618Y),以屏幕最左下角的坐标为(0,0),根据所设定的基准窗口的位置,即可确定视频显示区域的各个视频窗口的坐标显示范围,从而得到所有的视频窗口的显示布局。 [0042] and the video display area allocated according to the display range for each video window display resolution, preferably, the principles of allocation golden section, the center point of the reference line of the window is provided in the display device, i.e., the video window the center point of the ordinate at the point of the screen dividing point golden ordinate entire display apparatus (the height from the bottom of the screen most of 0. 618Y), to the lower left corner of the screen coordinates (0,0), based on the set position of the reference window, the video display to determine the coordinates of each video window display area range, to thereby obtain the display layout of all the video window.

[0043] 需要说明的是,当N为奇数时,如图4所示,基准窗口水平显示在显示区域的中间; 当N为偶数时,两个基准窗口既可以水平拼接,也可以如图5所示,以一定的角度进行拼接。 [0043] Incidentally, when N is odd, as shown in FIG. 4, the reference window is displayed horizontally in the middle display area; when N is even, the level of the two reference windows may be spliced, as shown in 5 shown, at an angle stitching.

[0044] 对于基准窗口两边的视频窗口拼接角度α的设置,原则上是需要显示的视频窗口越多,则α越小,倾斜越大的,观看者会感觉离到距离越近。 [0044] The more video mosaic window for the video window reference angle α on either side of the window is provided, in principle, is to be displayed, the smaller α, the greater the inclination, the viewer will feel from the closer. 例如,在4人进行的视频会议上,拼接角度为5度较为合适。 For example, in a video conference conducted on 4, splice angle of 5 degrees is more suitable.

[0045] 假设观看者站在圆桌的中心位置,正面观看的视频窗口为平行正放的,也是离自己最远的;然后离自己近的视频窗口需要侧着观看,观看到的窗口会呈现一定的向下倾斜度,越近越倾斜度越大。 [0045] assume that the viewer standing in the center of a round-table position, the front window to watch the video being put in parallel, but also from their furthest; then from their recent sideways to watch video windows need to watch the window will show a certain the downward inclination, the greater the closer the inclination. 显示在2D的屏幕上,观看者就有远近的感觉,观看的视频窗口呈现一个圆桌显示。 2D display on the screen, the viewer will have the feeling of distance, watch video window presents a round-table display.

[0046] 上述显示方式是将观看者的位置定义为圆桌中心时的情况,若将观看者的位置定义为圆桌的一端时,则视频窗口的显示方式如图6所示,视频窗口的排列为向上倾斜的方式。 [0046] The display position of the viewer is defined as the case when the center of the round table, while if the position of the viewer is defined as the end of the round table, the display mode of the video window shown in Figure 6, the video window is arranged upward sloping way.

[0047] 另外,在应用的本发明过程中,可以预先将不同N值生成的显示模板存储起来,在需要进行调整时,检测出需要显示的视频窗口的数量,然后提取出相应数量时进行的显示模板,将视频分别发送至对应位置进行显示。 [0047] Further, in the process of the present invention is applied, it is possible in advance to a different value of N to generate a display template stored in the adjustment is needed, the detected number of video windows to be displayed, and then extract the corresponding quantity for the display template, are transmitted to the corresponding video display position.

[0048] 进一步地,在显示装置的屏幕下部显示背景衬托地球弧形图,如图7所示,该地球弧形图与视频窗口的弧形相互衬托,空间感会更强烈。 [0048] Further, in the lower display device is a display backdrop to FIG earth arcuate, shown in Figure 7, the arcuate FIG earth arcuate mutual background video window, it will be more strongly a sense of space.
