Further, as to the further expanding of method embodiment shown in Figure 2, the method that the embodiment of the invention also provides a kind of image to show.Receive the wireless image data instance that four electronic equipments send simultaneously with intelligent television, as shown in Figure 3, said method comprises the steps:
301, receive the picture frame of four electronic equipment wireless transmissions through WI-FI.
According to the design feature of intelligent television, intelligent television receives the mode of electronic equipment picture frame and does not limit following three kinds:
1) when intelligent television built-in or extrapolation during the WI-FI chip of equivalent amount, the picture frame that can send through four electronic equipments of four WI-FI chip parallel receives.
2) when intelligent television only built-in or extrapolation during a WI-FI chip, can receive the picture frame that four electronic equipments send successively through this WI-FI chip.Concrete; The WI-FI chip receives first picture frame of electronic equipment A, first picture frame of electronic equipment B, first picture frame of electronic equipment C, first picture frame of electronic equipment D in proper order, continues to receive successively second picture frame of electronic equipment A, second picture frame of electronic equipment B, second picture frame of electronic equipment C, second picture frame of electronic equipment D then ... by that analogy it.
3) but the WI-FI number of chips of or extrapolation built-in during more than the quantity of a not enough electronic equipment when intelligent television; Can part WI-FI chip according to mode 1) picture frame of man-to-man reception electronic equipment, part WI-FI chip is according to mode 2) picture frame of the reception electronic equipment of one-to-many.
Need to prove; Because the WI-FI chip receives the speed of picture frame and is generally a millisecond rank; In the above described manner 2) and mode 3) in receive the multiple electronic equipment picture frame successively mode can not produce the time sequence difference on user's sense organ, can not exert an influence to showing four picture frames in the step 305 simultaneously.
302, the picture frame that receives is decoded.
Picture frame is identical with receiving, the mode that the picture frame decoding also can be adopted parallel decoding or decode successively, and the foundation of selecting decoding process is for receiving the mode of picture frame.The picture frame decode rate of intelligent television is similarly a millisecond rank, so on user's sense organ, do not produce time sequence difference equally.
303, the quantity according to electronic equipment is divided into four sub-display section territories with on-screen display (osd) area.
Intelligent television is divided at least two sub-display section territories according to preset division rule with on-screen display (osd) area, and the quantity at least two sub-display section territories is no less than the quantity of at least two electronic equipments.
The mode of dividing on-screen display (osd) area includes but not limited to following four kinds:
A) shown in Fig. 4 (a), do line of demarcation, three long limits respectively at on-screen display (osd) area broadside 1/3rd places, this line of demarcation, three long limits is parallel to the long limit of on-screen display (osd) area, on-screen display (osd) area is divided into the sub-viewing area of four homalographics.
B) shown in Fig. 4 (b), do three broadside lines of demarcation at 1/3rd places, the long limit of on-screen display (osd) area respectively, these three broadside lines of demarcation are parallel to the broadside of on-screen display (osd) area, on-screen display (osd) area are divided into the sub-viewing area of four homalographics.
C) shown in Fig. 4 (c); Do a broadside line of demarcation at 1/2nd places, the long limit of on-screen display (osd) area respectively; Do line of demarcation, a long limit at on-screen display (osd) area broadside 1/2nd places; These two lines of demarcation are divided into the sub-viewing area of four homalographics with on-screen display (osd) area, and promptly sphere of movements for the elephants shape is divided.
D) preset dividing line by manufacturer according to the display effect maximization principle, said preset dividing line is satisfied to be divided into four sub-display section territories at least with on-screen display (osd) area.Perhaps, according to the preset dividing line of user's personal like, the sub-viewing area that said preset dividing line marks off is no less than four equally, (d) among Fig. 4 and (e) two kinds of possible dividing mode are provided.
Need to prove; Above-mentioned dividing mode is to be that example describes with the picture frame that shows four electronic equipments simultaneously; Need divide on-screen display (osd) area according to concrete demonstration way in the practical application, division principle is that sub-viewing area number is no less than the demonstration way.Unnecessary sub-viewing area can show complete white or complete black, perhaps shows the still image that manufacturer is preset.For example shown in Fig. 4 (f); When showing that way is seven the tunnel; Can not do two lines of demarcation, long limit and two broadside lines of demarcation with 1/3rd punishment of long limit at on-screen display (osd) area broadside 1/3rd places; These four lines of demarcation are divided into nine sub-display section territories of homalographic with on-screen display (osd) area, and promptly nine palace lattice types are divided.Unnecessary sub-viewing area, the on-screen display (osd) area lower left corner shows complete black.
Above-mentioned dividing mode is the example explanation with the homalographic dividing mode, also can on-screen display (osd) area be divided into a plurality of sub-viewing area of non-homalographic in the practical application.For example, shown in Fig. 4 (g), when showing the two-way picture frame, can on-screen display (osd) area be divided into a sub-display section territory (regional A among the figure) and a female viewing area (area B among the figure) unequal two viewing areas of two areas.
Above-mentioned described dividing line is not the physical division line, but the virtual dividing line definite according to the pixel coordinate position.Article one, dividing line takies delegation or multirow pixel, and when the displayed map picture frame, the pixel that dividing line takies can show complete black.
304, the resolution compression with decoded picture frame is the resolution that shows the sub-viewing area of this picture frame.
With 1920*1080 high-definition format display screen is example: this screen width is 1080 pixels, and promptly screen laterally has 1080 scan lines, and length is 1920 pixels, and promptly screen vertically has 1920 scan lines.When in whole on-screen display (osd) area, showing one road picture frame, if the resolution of this picture frame is 1920*1080, then directly show, need not to adjust the resolution of picture frame.When on-screen display (osd) area shows four road picture frames; As shown in Figure 5; With the four sub-display section territories (being the first, second, third and the 4th sub-viewing area among Fig. 5) that on-screen display (osd) area is divided into sphere of movements for the elephants shape, then the resolution of each sub-viewing area is 960*540.If the resolution of every road picture frame still is 1920*1080, then need the resolution of picture frame be adjusted into 960*540.
Special, for erose sub-viewing area, can pixel matrix be set according to the shape of sub-viewing area, the line number of pixel matrix is the maximum number of lines of this sub-viewing area, the columns of pixel matrix is the maximum number of column of this sub-viewing area.In the pixel matrix each has 0 and 1 two kind of value, is to represent that this pixel was positioned within the sub-viewing area at 1 o'clock, is to represent that this pixel was positioned at outside the sub-viewing area at 0 o'clock, and the pixel in the Frame outside the corresponding sub-viewing area will not show.Can adjust the resolution of picture frame according to pixel matrix.
305, in four sub-display section territories, show four picture frames simultaneously.
Four picture frames need show on each self-corresponding sub-viewing area; Because picture frame is to exist with the pixel matrix form; Wherein the position between the pixel concerns relative fixed; So, just can picture frame be presented on the corresponding sub-viewing area as long as the pixel position of first row, first row in the pixel matrix is corresponding with the pixel position of sub-viewing area first row, first row.Still as shown in Figure 5, for the picture frame that is shown on the second sub-viewing area, can the pixel of these picture frame first row first row be navigated on the pixel of the 1st row the 961st row on the on-screen display (osd) area, i.e. some A among Fig. 5.
And for which picture frame be shown on which sub-viewing area, then can pre-seting by manufacturer or user, the embodiment of the invention does not limit this.
306, the quantity of monitoring electronic equipment.
Optional, when showing four road picture frames at the same time, can also monitor the increase and decrease of the quantity of electronic equipment.The number of electronic devices that monitors can be used as the foundation of dividing on-screen display (osd) area.
307, when the quantity of electronic equipment has increase and decrease, repartition on-screen display (osd) area according to the quantity of the electronic equipment after the increase and decrease.
When the quantity of electronic equipment reduces, can repartition on-screen display (osd) area according to number of electronic devices and the described implementation of step 303 after reducing.Perhaps do not repartition on-screen display (osd) area, the sub-viewing area that the picture frame of minimizing is corresponding is shown as no signal or complete black.
When the quantity of electronic equipment increases, can repartition on-screen display (osd) area according to number of electronic devices and the described implementation of step 303 after increasing.When the number of electronic devices after increasing is no more than atom viewing area quantity, also can not repartition on-screen display (osd) area.
The electronic equipment of quantity increase and decrease had both referred to carry out with intelligent television the electronic equipment of wireless image transfer of data, also can be and be that intelligent television belongs to the electronic equipment in the same application scenarios.
After repartitioning on-screen display (osd) area, handle according to the picture frame of step 304 and step 305 pair current way, concrete implementation please refer to step 304 and step 305, repeats no more here.
Optional, can also be the resolution of this picture frame before the adjustment with the resolution recovery of images displayed frame in any sub-display section territory.For example can the picture frame of any 960*540 resolution be reduced to 1920*1080 resolution among Fig. 5, on whole on-screen display (osd) area, show then.
The rule of selective reduction picture frame can be to receive user instruction, according to user's demand reduction picture frame.Perhaps, the significance level according to each road picture frame content engraves this picture frame when preset.For example, at the highest picture frame of a certain preset moment reduction priority.
