Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in the accompanying drawing, yet should be appreciated that and to realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order to understand the disclosure more thoroughly that these embodiment are provided, and can with the scope of the present disclosure complete convey to those skilled in the art.
Referring to Fig. 1, the embodiment of the invention provide a kind of in remote control process the method for the transmission of data, the method can may further comprise the steps:
S101: with after main control end is set up Long-distance Control and is connected, the desktop background of controlled end is shown as monochrome;
In embodiments of the present invention, consider in the process that the display interface data with controlled end transmit to main control end, in fact greatly data are the desktop backgrounds that represent controlled end, and generally speaking, the controlled end user may desktop background be set to comparatively complicated picture, when transmitting such image data, just need to take larger transmission bandwidth.But in fact, the desktop background of controlled end is in fact fully nonsensical for the remote assistance operation, and therefore, shared transmission bandwidth is actually a kind of waste on transmission desktop background picture.If can reduce this part data, then can greatly save the taking of transmission bandwidth, can not affect normally carrying out of remote assistance service simultaneously yet.For this reason, in embodiments of the present invention, with after main control end is set up Long-distance Control and is connected, be not directly the display interface of controlled end to be carried out sectional drawing, but at first the desktop background of controlled end be shown as monochrome, and then carry out the transmission of image.Like this, will be so that the display interface of controlled end become fairly simple, carry out sectional drawing on basis, simple displaying interface and then when picture encoded, the quantity of information that needs will be fewer, and then when carrying out the transmission of data message, the transmission bandwidth that takies also will be fewer.
Wherein, when the desktop background of controlled end was set to monochrome, concrete color value can be arbitrarily, for example, can be black etc.During specific implementation, can by the mode of list item corresponding in the edit the registry, realize that desktop background is set to the monochrome of certain color value.For example, registry entry HKEY CURRENT USER Control Panel the key assignments of Wallpaper under the Desktopd represent the filename of the picture that desktop background uses, therefore, for desktop background being changed into monochromatic value, at first just can change the key assignments of this registry entry into sky, so just can be so that the desktop background picture be nothing, also, not any pictures is set to the desktop background picture; Simultaneously, can by edit the registry item HKEY CURRENT USER Control Panel the key assignments of Background under the Colors, the desktop background color is set to needed color.Wherein, the key assignments of Background is character string type, this character string is divided into three sections, between every section with " space " as separator, three segment datas represent respectively trichromatic value, also are red R, green G, blue B, the span of every segment data is 0 to 255, therefore, can by being three numerical value corresponding to section input, just can realize the modification to the desktop background color.For example, the key assignments of Background is set to " 000 ", and then desktop background will be shown as black, and the key assignments of Background is set to " 255 00 ", and then desktop background is shown in red, etc.In actual applications, the color value of desktop background can be selected arbitrarily.Certainly, when specific implementation, can write in advance corresponding program at the remote assistance instrument, and in program, set the rgb value of required desktop background color, then revise the registry entry of system by this program, can realize that above-mentioned controlled end desktop background is set to monochrome.
Need to prove, because it only is in order to reduce taking transmission bandwidth in the process of remote assistance service that the desktop background of controlled end is changed into monochrome, therefore, after the remote assistance process finishes, state before can also automatically desktop background being returned to, and after desktop background is changed into monochrome, all right prompting user, " for so that the process of remote assistance is more smooth; need to temporarily change its desktop background into certain color; after remote assistance is finished, can automatically recover ", etc.Perhaps, can also before revising, the inquiry user whether allow desktop background is carried out provisional modification, if the user agrees to revise, again its desktop background be made amendment.
In order automatically desktop background to be returned to the state before revising, before desktop background is set to monochrome, can also obtain the desktop background information of controlled end, and it is saved in the registry file of an appointment.Wherein, so-called desktop background information, the path that can comprise the picture that desktop background is used, and the display mode of background picture (between two parties, tiling or stretching), also namely, need to be informed in before the modification, what desktop background adopted is that width of cloth picture, this picture is to show in mode placed in the middle, that tile or stretch, and these information are kept in the registry file.Then, when needs recovery desktop background arranges, just can read out the desktop background information of preserving in this registry file, then get final product by the desktop background of using these information to reset controlled end.
Wherein, specifically when obtaining desktop background information, can obtain by reading registration table the key assignments of the registry entry of appointment, get access to the display mode of desktop background picture according to this key assignments, simultaneously, the API(Application Programming Interface that can provide by the call operation system, application programming interface) mode of function, obtain the storing path of desktop background picture, which width of cloth picture what also namely know the controlled end use is.For example, by read HKEY_CURRENT_USER Control Panel WallpaperStyle under the Desktop and the key assignments of these two registry entries of TileWallpaper, can get access to the display mode that the desktop background picture uses.For example, also be 0 if the key assignments of TileWallpaper is the key assignments of 0, WallpaperStyle, then represent the display mode of desktop background picture for placed in the middle; If the key assignments of TileWallpaper is the key assignments of 1, WallpaperStyle is 0, the display mode that then represents the desktop background picture is tiling; If the key assignments of TileWallpaper is the key assignments of 0, WallpaperStyle is 2, then represent the display mode of desktop background picture for stretching.Therefore, by reading the key assignments of these two registry entries, which kind of display mode what can know current desktop background picture employing is.
Simultaneously, the mode of the API that can provide by calling system is obtained the storing path of desktop background picture.This api function can be SystemParametersInfo, and the SystemParametersInfo function can be used for inquiring about or arranging system-level parameters, can get access to by this function the path of the desktop background picture of controlled end use.
After the path that gets access to the desktop background picture and display mode, just these information can be kept in the registry file (take the file of reg as the suffix name).Like this, in the time the desktop background of controlled end need to being returned to the state of revising before, just can from this registry file, read out the desktop background information of preservation, then the key assignments of revising corresponding registry entry with these information (for example, can comprise TileWallpaper, WallpaperStyle, Wallpaper, the value of ConvertedWallpaper and OriginalWallpaper), then the api function that provides of the calling system desktop background of notifying operating system to refresh controlled terminal based on amended registration table key assignments just can be so that the desktop background of controlled end returns to the state before revising.For example, can call the SystemParametersInfo function equally, its parameter is set to SPI_SETDESKWALLPAPER, can notify operating system to use amended registration table key assignments that the desktop background picture is set.
Wherein, when specific implementation, the time point that recovers desktop background information can have a plurality of.For example, after finishing a Long-distance Control service, carry out the operation that recovers desktop background information.Wherein, can will disconnect event that Long-distance Control is connected as the sign of finishing the Long-distance Control service with main control end, and, receive disconnect with main control end between Long-distance Control be connected message the time, at first carry out to recover the operation of desktop background information, and then being connected between disconnection and the main control end.Perhaps, also can will withdraw from the event of remote control program as the sign of finishing the Long-distance Control service, also be, when receiving the message that withdraws from remote control program (also disconnect with main control end between be connected after, when for example the user clicks the X button of controlled end remote control program), at first carry out the operation that recovers desktop background information, and then finish the remote control program of controlled end.
Certainly, if will disconnect the event that Long-distance Control is connected or the event that withdraws from remote control program as the trigger event that recovers desktop background with main control end, in case then remote control program breaks down in operational process and causes unusually withdrawing from, then desktop background can't automatically restore to virgin state.For fear of the generation of this situation, a plurality of time points for recovering can be set, for example, can comprise that Long-distance Control connects when disconnecting, when remote control program withdraws from, when remote control program starts next time, etc.; And as long as finished the recovery of desktop background at any one time point, just with the desktop background information deletion of preserving in the registry file.Like this, whether each time point can be empty by judging in the registry file just, judge whether to carry out the recovery operation of desktop background, if be empty, then proof has been carried out the over recovery operation, then no longer repeats recovery operation, if be not empty, then proof is not yet carried out recovery operation, therefore just can carry out recovery operation.For example, suppose remote control program because the fault Anomalies Caused withdraws from, not yet carry out the recovery operation of desktop background, then when remote control program startup next time, find that registry file is not empty, just can prove that desktop background not yet recovers, and concrete recovery operation gets final product according to the information and executing of preserving in the registry file.
The above is to decide the recovery of carrying out desktop background when in its sole discretion by controlled end, in actual applications, because concrete assistance operation is sent in main control end, controlled end is just carried out the instruction that main control end is sent, and main control end knows more easily when what remote assistance service can finish.Therefore, also can send recover indication to controlled end by main control end, controlled end can be after the indication of receiving main control end like this, and the desktop background of controlled end is reverted to virgin state.Wherein, the recovery indication that main control end is sent, can manually be sent by the main control end user, for example, after the main control end user has finished all operations of this time serving, can be at first send an instruction that recovers desktop background to controlled end, treat that controlled end finishes after the recovery operation of desktop background, send again and the instruction such as disconnect.Certainly, main control end also can be send disconnect instruction in or afterwards, send the instruction that recovers desktop background, etc.
S102: determine image waiting for transmission;
After the desktop background of controlled end is set to monochrome, just can determine image waiting for transmission, prepare for transmitting to main control end.Wherein, when determining image waiting for transmission, can carry out sectional drawing to the display interface (comprising icon, start menu, the taskbar on desktop background and the desktop and the program tag that wherein shows etc.) of controlled end, then directly with the image that is truncated to as image waiting for transmission, then this image is encoded, send the data message that obtains to main control end and get final product.Because desktop background is set to monochrome, therefore required data volume will diminish when the display interface picture that is truncated to is encoded, and is corresponding, will reduce taking transmission bandwidth when carrying out data transmission.
Perhaps, the embodiment of the invention can also combine with the piecemeal transmission of image.When in the remote assistance process, carrying out image transmitting; usually can adopt the subregion update mode of picture to carry out the renewal of image; that is to say; equally for the consideration to the reduction transmission bandwidth; if controlled end find with on one constantly compare; only have the image of subregion that variation has occured in the screen, other regional constant, the area image that conversion then can only this part have been occured is transferred to main control end.Upgrade in order to realize this subregion, usually need to carry out piecemeal to image, also namely before transmission, first image is divided into block one by one, and then these blocks are encoded respectively, and coded message and the coordinate of each block (comprised the origin coordinates of each block, shared wide high pixel value, etc.) send to main control end, convert picture in main control end to according to the coded message of each block, and according to coordinate figure separately each block is made up, obtain complete image, thereby show the display interface of controlled terminal.If controlled end is after next obtains image to the display interface sectional drawing constantly, can carry out piecemeal to image in the same way, then with upper one constantly the block on the correspondence position compare, the block that only conversion will occur is encoded, and data message and coordinate corresponding to block that obtains sent to main control end, and upper one constantly then can repeat again to send to main control end than the block that does not change.Main control end can make up the block that changes that newly receives and the block that does not change that originally received according to separately coordinate, obtain complete image, by that analogy.
And in embodiments of the present invention, after the desktop background of controlled end is set to monochrome, the display interface image that grabs can be divided into a plurality of blocks according to certain mode equally, then with each block as image waiting for transmission, and then each block encoded, re-send to afterwards main control end.
Need to prove, about specifically how image being carried out piecemeal, and the coordinate of each block of how to confirm, wide high, can referring to the implementation in the prior art, no longer describe in detail here.
S103: if comprise all or part of desktop background in the described image waiting for transmission, then send described monochromatic corresponding colour to described main control end, so that main control end shows the desktop background of controlled end according to described colour.
After having determined image waiting for transmission, just can treat transmitting image and encode, the data message that obtains is sent to main control end, in order to demonstrate the display interface of controlled end in main control end.Wherein, if comprise all or part of desktop background in the image waiting for transmission, then just can send the monochromatic corresponding colour of desktop background to main control end.Wherein, in the situation that the transmission of combining image piecemeal, effect is particularly evident.This be because, generally speaking, having very large area in the display interface is desktop background, for example, if the user does not open any program window, then may only show some icons in positions such as left sides in user's the display interface, show START button and status bar below, remainder is desktop background; Like this display interface image is carried out after the piecemeal, in each block that obtains, just may having greatly, block all is only to comprise desktop background, therefore, for such block, as long as the coordinate of this block and the colour of desktop background are sent to main control end, and need not again each pixel in this block be encoded, therefore, greatly save amount of coded data, and then saved transmission bandwidth.
And for the block that not only comprises desktop background, the embodiment of the invention also provides corresponding method for encoding images, to reduce as far as possible taking transmission bandwidth.Concrete, can judge the color category that comprises in the block, if only have two kinds of colors, then can carry out respectively index to two kinds of colors, then with two kinds of colors respectively corresponding index value described current block is encoded, again with coding result, and the corresponding relation of index value and color value sends main control end to, main control end just can be according to coding result like this, and the corresponding relation of index value and color value, demonstrates current block.For example, after getting access to two kinds of color values, can represent wherein a kind of color value with 0, with the another kind of color value of 1 representative, then index with 0 and 1, by in the block from top to bottom the order of delegation of delegation each pixel is encoded, for each pixel, if the first color value just is encoded into 0, if the second color value just is encoded into 1.Like this, index value only has one, and the color value that index value is corresponding can be 24, is specially what color because color value need to be expressed by the concrete value of RGB.Namely have a talk about, in this manner, do not need each pixel is encoded with 24 color value, but only come each pixel is encoded with 1 index value, simultaneously with two index values respectively corresponding color value send to main control end and get final product.In other words, suppose that certain block has 10,000 pixels, if then each pixel is encoded with 24 color value, then the data volume behind the coding is at least 240,000 bits, and if the coded system that provides according to the embodiment of the invention, the data volume behind the coding only is 10,000 bits, and in addition only need to can express corresponding relation between encoded radio and the color value by the data of tens bits, as seen, this mode greatly reduces the required data volume of Image Coding, and then saves transmission bandwidth.
In addition, if the color value that comprises in certain block is above three kinds, then can judge the flatness of tile images, then determine the compress mode of this block according to judged result, compress with the image of this suitable compress mode to this block, then the view data after will compressing sends main control end to, so that main control end shows current block according to the view data after compressing.For example, if smoothly would use JPEG(Joint Photographic Experts Group, joint image expert group) algorithm compresses, if unsmooth then compress with the ZIP algorithm.Wherein, so-calledly smoothly be and sharp-pointed relative concept, smoothly just refer in the image the excessively milder of color between each image, the entire image picture is softer, edge boundary too clearly not, etc.When judging that piece image is whether level and smooth, can judge that whether the summation of the color distortion of adjacent image point in the image is less than a threshold value (its value can be set or adjust according to the actual needs), if less than, prove that then this image is smoother, and then the jpeg algorithm that can select to be more suitable for smoothed image compresses; Otherwise this image is unsmooth, and is also namely more sharp-pointed, and then the ZIP algorithm that can select to be more suitable for unsmooth image compresses.Certainly, because the image compression algorithm that different blocks adopts may be different, therefore, for main control end can correctly be decoded, can also be in the data message after main control end transmission compression, carry the image compression algorithm of corresponding block, so that main control end is utilized corresponding decompression algorithm, recover corresponding tile images.
Wherein, ZIP is a kind of harmless compress mode, and for the image of determining, its compression factor is identical; But jpeg algorithm then can require to adjust its compression factor according to different compression qualities, and, in the situation that identical compression quality, smoothness and compression factor are inversely proportional to, also be, when using jpeg algorithm that level and smooth image is compressed, if required compression quality is certain, then can select according to the smoothness of image the compression factor of jpeg algorithm, if the smoothness of image is higher, then can use lower compression factor, otherwise, if the smoothness of image is lower, the compression factor of then also using is also higher.In addition, in the situation of identical compression factor, image compression quality is directly proportional with Image Smoothness, and also, Image Smoothness is higher, and then image compression quality is also just higher.
Need to prove, specifically in judging a block during quantity of that color value that comprises, can travel through each pixel in the zone, when learning the color value of first pixel, this color value is kept in the color value table, learn after the color value of next pixel, at first judge and whether have this color value in the color value table, if not in table, then a new color is found in representative, simultaneously this color value is inserted in the color value table, if suffered at the color value table, then continue traversal, by that analogy, finally just can learn in the block to comprise altogether what pixel values.Certainly, as mentioned before, if find to comprise in the block color value more than three, just adopt the mode of judging smoothness to select compression algorithm to compress rear transmission, therefore, in the process of traversal, after finding three kinds of color values, just can stop traversal, to save the running time.
In addition, in actual applications, if when comprising three kinds even more colors in the block, also can use when having color value with aforementioned two kinds similar indexing means that image is encoded, just very many at the color value that comprises, to such an extent as to the shared bit number of index value during near the shared bit number of color value, just there is no need to carry out in this manner index, selects compress mode to compress according to smoothness and gets final product.
In a word, after the controlled end desktop background is set to monochrome, can reduce as much as possible in several ways taking transmission bandwidth.When the data-message transmission of controlled end after main control end, main control end just can be resolved the data message, and restores the image of controlled end display interface.Simultaneously, at controlled end, also can be according to the display interface of Preset Time gap periods scanning controlled end, the change color that comprises in one or more described blocks in the each scanning of monitoring, with the block coordinate that changes, and the Image Coding result after changing, send to main control end, so that main control end according to described coordinate and Image Coding result, shows corresponding one or more blocks.
