Embodiment
Below will coordinate graphic and embodiment to describe embodiments of the present invention in detail, and by this present invention's implementation procedure how application technology means solve technical problem and reach technology effect can be fully understood and be implemented according to this.
Core idea of the present invention is: in local side, obtain forms, described forms are divided into Bing Weige region, some regions the scan period is set respectively; At local lateral root, according to the scan period in each region, respectively each region is scanned, according to each region, whether in concerned state, adjust the scan period in each region, and the region that image is changed is transferred to network side.
Described region detected in concerned state, the following one or more combination of foundation: passed through, compare and change with the image that the upper one scan cycle obtains by mouse click, mouse track; Described forms, it can be system desktop, also can be that system desktop is divided into a certain region behind some regions, also can be one of region to obtaining behind a certain zone subdivision district, also can be emerging forms on desktop, also can be the forms (as zooming in or out forms) that shape changes, the present invention be not limited to this.
With an embodiment, the subregion transmission method for Long-distance Control of the present invention is described below.User accepts the request of server, take over user's terminal and carry out Long-distance Control, in the process of Long-distance Control, need server and capture in real time or periodically the desktop of user terminal, and the form that saves as picture sends on server and shows, thereby on server, reduce the desktop of user terminal, the personnel that maintain easily control user's terminal on server.
Subregion transmission method for Long-distance Control of the present invention, is applied to serve the effective family of side joint side when carrying out Long-distance Control, captures the process of the desktop of user terminal.As shown in Figure 1, specifically comprise following operation:
Step S1, obtains forms in local side, and described forms are divided into some regions, performs step respectively S2 and S7;
According to the GDI of internal system (Graphics Device Interface GDI), obtain described forms; Described forms are divided into some regions by any-mode, for example, can affiliated forms be divided into nine regions by nine grids, also can be divided into 16 lattice etc., the present invention is not limited to this; In local side, also need to obtain the initial pictures of described forms and be sent to network side, at network side, based on described initial pictures, described forms being reappeared afterwards;
Step S2, for each region arranges respectively the scan period separately;
Be now initial condition, acquiescence is the identical scan period by each region division;
Step S3, scans each region respectively according to the scan period in each region at local lateral root, performs step respectively afterwards S4 and step S6;
Whether whether the image in each region is obtained in scanning, can also obtain each region simultaneously and by mouse, be clicked, by mouse track, passed through;
Step S4, the region that image is changed transfers to network side;
For each region, the image of the current region that scanning is obtained, compares with the image that current region obtained in the upper one scan cycle, if changed, by the image transmitting in described region to network side; The positional information in the region that image is changed also transfers to network side together; The region that image changes can be that the content of the forms in this region changes, and the forms that in this region, appearance is newly opened can be also that the forms that shape changes are stretched over (as zooming in or out forms) in this region;
Step S5, relevant position in described network side is substituted into described forms by the image in the region receiving, reappears described forms at described network side, and flow process finishes;
In a certain moment, receive the image in a region at described network side, according to described positional information, the image in the region receiving is substituted into the relevant position of described forms, thereby reappear at network side the described forms that this constantly local side shows;
Whether step S6, adjust the scan period in each region according to each region in concerned state, return to execution step S3;
To each region, give a weight, according to different proportion ranges, be set the corresponding scan period; According to the scan period in each region, detect respectively each region and whether in concerned state and for each region, adjust weight, according to the residing proportion range of the weight in each region, adjust the scan period in each region;
For example, for a certain region, described region is scanned according to the scan period in described region, when described region being detected in concerned state, increased the weight in described region, as increased to before maximum, no longer increase, now keep maximum; When described region being detected not in concerned state, reduce the weight in described region, as reduced to before minimum value, no longer reduce, now keep minimum value; Weight is higher, and the scan period is shorter; Weight is lower, and the scan period is longer; Whether detect a certain region in concerned state, can detect whether described region is clicked by mouse and/or whether by mouse track through and/or whether compare and change with the image that the upper one scan cycle obtains; In practical operation, it is generally acknowledged, described region is clicked and is thought that it is in concerned state by mouse, described region is by mouse track through thinking that it is in concerned state, and the image in described region is compared with the image that the upper one scan cycle obtains to change and thought that it is in concerned state;
For example, can also to described region, scan according to the scan period in a region, described region be detected in concerned state, increase the weight in described region; Described region detected not in concerned state, no longer described region was scanned by its scan period, but just single pass is carried out in described region when described region often being detected in concerned state, for some not concerned regions, can carry out event-triggered scanning like this, further reduce the consumption of processing resource;
Step S7 scans each region every a fixed cycle in local side simultaneously, and situation about changing according to image is adjusted the scan period in each region, and the region that image is changed transfers to network side, execution step S5;
The longer region of scan period for being considered in step S2-S6 not in concerned state, if emergent image can find in time and obtain by the mode of this step, and can adjust the scan period in the short region changing; The positional information in the region that image need to be changed in addition, also transfers to network side together.In realization, every the fixed cycle, each region is scanned also simultaneously and can be realized by such mode: the configuration rule to the scan period, be defined as and with a base cycle, carry out multiple and increase, such as: 0.5 second, 2 seconds, 4 seconds etc. be to be configured with 2 multiple, so just be equivalent to the longest scan period in each region, can to each region, carry out single pass simultaneously.
The present invention is for step S4 and S7, and the region that image is changed transfers to network side, the mode that can transmit by classification by the image transmitting in described region to network side.
The region that a certain image is changed, as shown in Figure 2, comprises the following steps:
Step SS1, obtains described region in local side;
Step SS2, is divided into some blocks by described region;
Described region is divided into some blocks by any-mode, for example, can described region be divided into nine blocks by nine grids, also can be divided into 16 lattice etc., the present invention is not limited to this;
Step SS3, the element wherein comprising for each block identification;
Described element, at least comprises: background, word and/or picture;
According to the GDI GDI of internal system, identify the background in the element in described block; For background, can be the picture that color is abundant, be likely also the picture of solid color;
The color category that described block is comprised is identified, and according to the quantity of described color category, identifies word and/or the picture in the element in described block; In general, the kind of the color that picture comprises can be abundanter, and relative picture, the color category that word comprises is comparatively single, therefore, can set a thresholding for color category, when the quantity of color category is less than described thresholding, identifying described element is word; When the quantity of described color category is greater than described thresholding, identifying described element is picture;
Certainly, can also carry out finer division to picture, can set the first thresholding and the second thresholding for color category, described the first thresholding is greater than the second thresholding; When the quantity of color category is less than described the second thresholding, identifying described element is word; When the quantity of described color category is greater than described the first thresholding, identifying described element is coloury picture; Described color category between the first thresholding and the second thresholding time, is identified as the not abundant picture of color;
Step SS4, for each block, find out the element of area occupied maximum wherein and judge that described element accounts for the proportion of the area of described block, if accounting for the proportion of the area of described block, described element surpasses a thresholding, execution step SS6, if accounting for the proportion of the area of described block, described element do not surpass a thresholding, execution step SS5;
In general, if the element of described area maximum accounts for the proportion of described block, surpass a default thresholding, can think that described block is mainly to consist of this element; If the proportion that described element accounts for described block does not surpass described thresholding, illustrate that element in described block is of a great variety and on average fill, described block is not to be mainly to consist of certain element;
Step SS5, is further subdivided into some secondary blocks by described block, for each secondary block, again performs step SS3, the element that identification wherein comprises;
Because described block is not to be mainly to consist of certain element, inhomogeneous element is applicable to different compress modes, so now cannot select applicable compress mode to described block; Can be further subdivided into some secondary blocks to described block, by any-mode, divide secondary block, for example, can described block be divided into nine secondary blocks by nine grids, also can be divided into 16 lattice etc., the present invention is not limited to this.If now still cannot determine main composition element in some secondary block, also can again divide secondary block, and carry out repeatedly iteration, the present invention is not limited to this;
Step SS6, is used with the corresponding compress mode of described element classification and described block is compressed and transfer to network side, the positional information of described block is also transferred to network side simultaneously;
Because described block is mainly to consist of this element, so use the corresponding compress mode of this element the most effective and applicable to this block;
For choosing of compress mode, can follow following principle:
To the block being mainly comprised of word, word is main object, and word often carries the data that need naked eyes identification, therefore need to guarantee the quality of data reduction, and the size of word itself is also less, can use Lossless Compression mode;
For the block being mainly comprised of the not abundant picture of color, the not abundant picture of color is main object, because the size of this picture itself is also little, can use lossless coding compress mode;
For the block mainly being formed by coloury picture, coloury picture is main object, for Long-distance Control, this picture is not often critical data, allow certain distortion, therefore lossy coding compress mode can be used, such as JPG, higher compression ratio can be obtained, greatly dwindle dimension of picture, when transmission, obtain higher speed.
Transmit and compare with the whole region of direct crawl, after such classified compression, the size reduction 30%-50% in region can be greatly reduced to data volume, and transmission rate is improved greatly;
Step SS7, at network side, receive and the image of each block that decompresses, positional information according to each block is recombinated to each block at network side, the most at last this time inscribe the region reduction that the image of local side changes, and described region is replaced to the relevant position that is presented at forms;
Positional information can be the transverse and longitudinal coordinate on the region that changes at image of each block.
Below with an application example, method of the present invention is described again.
User A accepts the request of server B, take over user's computing equipment to carrying out Long-distance Control, in the process of Long-distance Control, the form that needs server B and capture in real time or periodically the computing equipment desktop of user A and save as picture sends in server B and shows, thereby the computing equipment desktop of going back original subscriber A in server B, the personnel that maintain easily control the computing equipment of user A in server B.
When Long-distance Control, as shown in Figure 3, server B is divided into 16 regions by the desktop of the computing equipment of user A, and an initial weight 1 is given in each region; Set the corresponding scan period of proportion range 2-4 is 0.5 second simultaneously, and the corresponding scan period of proportion range 5-7 is 0.1 second, and described weight is higher, and the scan period is shorter; The full screen scan period is 2 seconds in addition.
Described region is scanned according to the scan period in each region, described region detected in concerned state, increase the weight in described region, described region detected not in concerned state, reduce the weight in described region; It is generally acknowledged, described region is clicked and is thought that it is in concerned state by mouse, described region is by mouse track through thinking that it is in concerned state, and the image in described region is compared with the image that the upper one scan cycle obtains to change and thought that it is in concerned state.
Through after a while, as shown in Figure 4, the weight of region A is 4 like this, the weight of region B is 7, according to the residing proportion range of its weight, can obtain the Mobile state setting of going forward side by side of corresponding scan period, the scan period of region A is 0.5 second, and the scan period of region B is 0.1 second;
Respectively each hot spot region is scanned every 0.5 second scanning area A, every 0.1 second scanning area B according to each sector scanning cycle; When scanning area B, discovery is compared the image that the upper one scan cycle obtains and is compared with region B, image does not change, and detect to find within this scan period also click on area B not of mouse, mouse track does not streak region B yet yet, think region B within this scan period not in concerned state, the weight of region B is reduced to 6, the scan period is still set to 0.1 second.Because B image within the current scan period in region does not change, do not need region B to issue network side;
When scanning area A, detect to find within this scan period also click on area A not of mouse, mouse track does not streak region A yet yet, but detect finding to compare with region A image that the upper one scan cycle obtains compares variation has occurred, think region A within this scan period in concerned state, the weight of region A is upgraded to 5, scan period relative set is 0.1 second, every 0.1 second, region A is scanned.Because variation has occurred region A image within the current scan period, need the image of region A to issue network side.
In order to guarantee the precision of remote monitoring, within every 2 seconds, carry out a full screen scanning simultaneously, All Ranges was scanned with 2 seconds identical cycles.For example, region C weight is 1, for a long time in non-concerned state, the scan period longer, in system desktop, a dialog box is ejected suddenly in the position of region C, as shown in Figure 5, now, according to the scan period of region C, find this dialog box and region C is transmitted and may be needed for a long time, or not yet scanning, this dialog box disappears, thereby may miss very important data when network side reappears; At this moment carry out a full screen scanning every 2 seconds, the dialog box of this ejection of discovery that just can be at the right time, and confirm that this image change occurs in region C, by the image transmitting of region C to network side, and now can think that region C is in concerned state, its weight is upgraded to 2, the corresponding adjustment scan period.
