Step 101: obtaining video window information from current control server, described video window information at least includes: any one apex coordinate of window (X1, Y1), window width W1 and high H1, window signal source name；
Generally, various video signals being shown, the whole processing procedure on combination is: by the control service centre of a combination in the display system of combination, sending and window instruction and send the video window information of the video signal that will export, it is to open video window that what is called is windowed；After receiving window instruction and video window information, the video signal that will export received is processed by combination processor, and is showing this video window according in video window information defined location.Most often applied video window shape is rectangle, i.e. each video window has four apex coordinates, be may determine that the particular location of video window by four vertex positions；Simultaneously, apex coordinate attribute properties according to rectangle: know wherein any one apex coordinate, rectangle width and the height in four summits of rectangle, i.e. can determine that other three apex coordinates, the coordinate-system of display screen just can correctly be determined the position of this video window.
Certainly, video window shape is square or rectangle, it is also possible to go to determine other vertex point coordinate information by the information of any one apex coordinate, height and width, so that it is determined that the position of video window.
Such as: current video signal wants output display, control service centre will send and perform the instruction message that transmission is relevant with the video window of required output simultaneously of windowing, this message at least includes: any one vertex point coordinate information of window, window width and high, window signal source name.Wherein, window signal source name is the caption information according to the video signal being configured needed for practical situation or user.When any one summit is lower left corner coordinate (X1, Y1), window width W1 and high H1, can calculate top left corner apex coordinate is (X1, Y1+H1), lower right corner apex coordinate is (X1+W1, Y1), upper right corner apex coordinate (X1+W1, Y1+H1).
Step 102: determine that window area is as first area according to any one apex coordinate of video window obtained and window width and height；
Such as: when the video window information obtained is: lower left corner coordinate (X1, Y1), window width W1 and high H1, can calculate top left corner apex coordinate by rectangular coordinates character is (X1, Y1+H1), lower right corner apex coordinate is (X1+W1, Y1), upper right corner apex coordinate (X1+W1, Y1+H1).The coordinates regional scope determined by these four summits is just as first area.
Such as: when the video window information obtained is: top left co-ordinate (X1, Y1), window width W1 and high H1, can calculate lower left corner apex coordinate by rectangular coordinates character is (X1, Y1-H1), lower right corner apex coordinate is (X1+W1, Y1-H1), upper right corner apex coordinate (X1+W1, Y1).The coordinates regional scope determined by these four summits is just as first area.
Utilize rectangular coordinates character to determine the coordinate on other summits by any one summit, height and width, have multiple implementation, numerous to list herein, also and be not specifically limited.
Step 103: generate a character shape window according to the window signal source name obtained；
Such as: video signal source is the outdoor scene information of Olympic Green, the window signal parent name in the video window information of acquisition is referred to as " Olympic Green ", will generate character to be shown in this window of character shape window for " Olympic Green ".
Step 104: described character shape window is shown in described first area.
Such as: the described character shape window " Olympic Green " generated is shown among first area.Be shown that the realistic picture of Olympic Green in first area, then what character shape window showed is exactly the caption information of this realistic picture.In actual applications, known what content that video information is specifically shown the most intuitively by caption information, preferably experience can be brought to user.
By above-described embodiment: obtain video window information from current control server；Determine that window area is as first area according to any one apex coordinate of video window obtained and window width and height；A character shape window is generated according to the window signal source name obtained；Described character shape window is shown in described first area.For there is no the video information of caption information when display, the caption information of this video information can be shown by this processing method when showing video information simultaneously, provide the user preferably experience.
Embodiment two
The method of the present invention must be explained in order to more preferable, it is described as a example by concrete application scenarios below, concrete scene is: having its signal source of video information is the geographical position image information near National Convention Center, but this video information does not has caption information, in order to make user more clearly know, on combination, the image information of display is any content, use each step in a kind of combination video window caption presentation method as shown in Figure 2, while realizing display video image information, show the caption information of this video.Specifically include following steps:
Step 201: obtaining video window information from current control server, described video window information at least includes: any one apex coordinate of window (X1, Y1), window width W1 and high H1, window signal source name；
Have a combination to control service centre in the display system of combination to show for the video controlling whole system, when combination control service centre receive the message being currently needed for showing a video information time, carry out instruction of windowing, transmission is currently needed for the video window information of the video information of display simultaneously, such as: having its signal source of video information is the geographical position image information near National Convention Center, but this video information does not has caption information.Include in the video window information sent: any one apex coordinate of window (X1, Y1), window width W1 and high H1, window signal source name；Wherein, any one apex coordinate is that lower left corner coordinate (1000,1000), window be a width of 3000, window a height of 2000, and window signal parent name is referred to as " National Convention Center ", and this window signal source name can be to pre-set according to the actual requirements.
Step 202: determine that window area is as first area according to any one apex coordinate of video window obtained and window width and height；
Such as: window shape is rectangle, any one apex coordinate obtained in video window information is lower left corner coordinate (1000,1000), window is a width of 3000, window a height of 2000, can calculate top left corner apex coordinate by rectangular coordinates character is (1000,1000+2000), lower right corner apex coordinate is (1000+3000,1000), upper right corner apex coordinate (1000+3000,1000+2000).The coordinates regional scope determined by these four summits is just as first area.
Certainly, if obtain video window information in summit, the Shi Fei lower left corner, any one summit time, by the coordinate relation on four summits of rectangle, equally determine other apex coordinates, and then determine that the region of video window is as first area.
Step 203: generate a character shape window according to the window signal source name obtained；
Preferably, step 203 includes: step 203A～tri-little steps of 203C, the method for establishment character shape window the most as shown in Figure 3.
Step 203A: create a square window object, and described square window and described video window formation mapping relations are set；
The home window that system provides in actual applications is square window, so first creating a square window, and arranging this square window and video window formation mapping relations, so-called mapping relations refer to corresponding relation, that is, this square window and video window are one-to-one relationships.Each window in systems has a window ID in order to identify this window, and the window ID of each window is unique.That is, reality application is exactly to form mapping relations one to one between the window ID of this square window and the window ID of corresponding video window.By the mapping relations formed, if it is known that the ID of a window just can utilize mapping relationship searching to go out the window ID of another window corresponding.
Step 203B: draw the window signal source name of acquisition in the device context of the square window object of described establishment；
Each window in systems has a device context region, associative operation can be carried out in this device context region, step 203B is only drawn in device context window signal source name.When drawing window signal source name, required font type and font size can be set, such as could be arranged to the Song typeface five or regular script three.A kind of font type and size are the most arbitrarily set.
Step 203C: obtain the character shape region of the signal source name drawn, the type of described square window is set to character shape window；
After drawing window signal source name in the device context region of square window, signal source name is to exist with character style, it is possible to obtains the character shape region that this window signal source name takies, then the type of square window is set to character shape window.
Step 204: described character shape window is shown in described first area.
Preferably, step 204 includes: step 204A and step 204B,
Step 204A: the coordinates regional of described character shape window is set: with the apex coordinate (X2 of any one vertex correspondence of the video window obtained, Y2), window width W2 and high H2, it must is fulfilled for following condition: X1 ＜=X2 ＜=(X1+W1), Y1 ＜=Y2 ＜=(Y1+H1), (X2+W2) ＜=(X1+W1), (Y2+Y2) ＜=(Y1+Y1)；
Such as: when the coordinate range of the first area determined is: lower left corner coordinate (1000,1000), top left corner apex coordinate is (1000,3000), lower right corner apex coordinate is (4000,1000) and upper right corner apex coordinate (4000,3000).Then according to the mode of step 204A, the coordinates regional of character shape window can be set in the range of first area.It is of course also possible to adopt in other ways, as long as the coordinates regional being capable of character shape window falls within the range of first area.
Step 204B: character shape window is moved to the coordinates regional arranged, and is set to top set and shows.
Such as: when the coordinates regional of the character shape window arranged is: top left co-ordinate (2000,2500) lower left corner coordinate (2000,1500), upper right corner coordinate (3000,2500), lower right corner coordinate (3000,1500) time, this window is moved to coordinates regional, is then set to top set and shows.
When moving video window or scaling process, the method also includes that following mobile Zoom display processing method, in order to the character shape window of video window and its correspondence to be adjusted display, specifically includes following steps:
Step 205: when receiving video window and moving scaling message, resolve described mobile scaling message and obtain the second area of video window, described second area at least includes: with the apex coordinate (X3 of any one vertex correspondence of the video window obtained, Y3), window width W3 and high H3；
Generally, usually operate or scaling mobile at needs etc. for convenience when processing, it is provided that window information in window summit with mobile before the window summit of offer be same summit.Such as: any one summit of the video window needing display of acquisition is specially top left corner apex, then the apex coordinate of the second area that the needs being resolved to move to also is the apex coordinate in the upper left corner.Certainly provided that be the coordinate information on other summits, be also the coordinate being readily able to calculate other summits.Such as: the second area of acquisition includes: lower left corner coordinate is that (2000,2000), window be a width of 6000, window a height of 4000.
Step 206: calculating the changes in coordinates value of video window first area and second area, described changes in coordinates value includes: window width changing value W3/W1, window High variation value H3/H1；
Video window first area refers to that video window moves or scale the band of position before process, video window second area refers to that video window moves or scale the band of position after process, is calculated the change in location value of the coordinate position of first area and the coordinate position of second area by the coordinate position of corresponding vertex.
Calculate according to the second area coordinate obtained and first area coordinate before: window width changing value is W3/W1=6000/3000=2, window High variation value H3/H1=4000/2000=2.
Step 207: according to the mapping relations of video window Yu character shape window, search the character shape window corresponding with video window；
In order to set up corresponding caption window, in step 203A to the video signal not having captions: create a square window object, and arrange described square window and described video window formation mapping relations；Described square window is exactly the character shape window determined afterwards.So, mapping relations according to video window Yu character shape window, search the character shape window corresponding with video window, may is that the mapping relations between the window ID of the window ID by video window and character shape window in actual applications, mapping relations are one to one between element, so when knowing the window ID of video window, it is possible to utilize mapping relationship searching to go out the window ID of corresponding character shape.
Step 208: adjust the coordinates regional of the character shape window of described lookup according to described changes in coordinates value, and character shape window is moved to the coordinates regional position after adjusting, including:
When the coordinates regional of the corresponding character shape window searched is the apex coordinate (X2 corresponding with any one vertex position of video window, Y2), during window width W2 and high H2, corresponding apex coordinate (the X4 of the character shape window after adjustment, Y4), window width W4 and high H4 meets following condition: X3 ＜=X4 ＜=(X3+W3) respectively, Y3 ＜=Y4 ＜=(Y3+H3), W4/W2=W3/W1, H4/H2=W3/W1.
nullWhen the coordinates regional of the corresponding character window searched is: top left co-ordinate (2000，2500) lower left corner coordinate (2000，1500)、Upper right corner coordinate (3000，2500)、Lower right corner coordinate (3000，1500)，I.e.，Window a height of 1000，Window a width of 1000、When calculating W3/W1=6000/3000=2、Window High variation value H3/H1=4000/2000=2，Corresponding apex coordinate (the X4 of the character shape window after adjustment，Y4)，Window width W4 and high H4 meets following condition: 2000 ＜=X4 ＜=(2000+6000) respectively，2000 ＜=Y4 ＜=(2000+4000)，W4/1000=2，H4/1000=2.Understand: 2000 ＜=X4 ＜=8000,2000 ＜=Y4 ＜=6000), W4=2000, H4=2000.Processed by calculating and can ensure that caption window change keeps consistent with the change of corresponding video window, zoom in or out into same ratio change, ensure that caption window shows within video window simultaneously.Above-mentioned only a kind of calculation, to determine the excursion of caption window, does not limit concrete calculation at this.
So that caption window is all the time in the relatively fixed position of video window, such as, before mobile change, caption window is at the lower right position of video window, after mobile change, caption window is also at the lower right position of video window, so that the mobile adjustment on window operates the relative position relation not affecting caption window with video window, preferably, step 208: adjust the coordinates regional of the character shape window of described lookup according to described changes in coordinates value, and character shape window is moved to the coordinates regional position after adjusting, including:
When the coordinates regional of the corresponding character type window searched is lower left corner coordinate (X2, Y2), during window width W2 and high H2, the coordinates regional of the character type window after adjustment is lower left corner coordinate (X4, Y4), window width W4 and high H4 meets following condition respectively:
(X2-X1)/W1=(X4-X3)/W2, (Y2-Y1)/H1=(Y4-Y3)/H2, W4/W2=W3/W1, H4/H2=H3/H1.
After calculating changes in coordinates value, the coordinates regional of the character shape window corresponding with video window can be adjusted according to changes in coordinates value, make the change of video window keep consistent with the change of character shape window.Such as: when video window reduces one times, and character shape window reduces one times the most therewith；Putting when video window and be twice, character shape window is put the most therewith and is twice.In a word, character shape window changes along with the change of corresponding video window.Behind character shape window coordinates region after determining adjustment, character shape window is moved on the coordinates regional position after adjusting.
When needing the character shape close by the video window shown and correspondence thereof, preferably, described method also includes: when receiving closedown video window message, by the mapping relations of video window Yu character shape window, find the character shape window corresponding with video window；Close video window and corresponding character shape window.
When needing the character shape close by the video window shown and correspondence thereof, control service centre and can send the instruction closing video window, explicitly point out the window ID of the video window needing closedown, then by the mapping relations of the ID of video window with the window ID of character shape window, find the character shape window corresponding with video window, finally close video window and corresponding character shape window.
By above-described embodiment it can be seen that utilize the method for the present invention to be possible not only to when being displayed without the video information of caption information, there is provided character shape window in order to show caption information for this video window, can also be when adjusting video window, corresponding adjustment corresponding character shape window, make whole display window synchronize change, provide the user the display of more preferable combination video and experience.
