Embodiment
A preferred embodiment according to the present invention is a kind of multi-computer switch.Refer to 2A-1 figure, 2A-1 figure illustrates the detailed functions calcspar of the multi-computer switch in this embodiment.As shown in 2A-1 figure, multi-computer switch 23 comprises communication unit 230, processing unit 231, storage element 232, coding unit 233 and acquisition unit 234.Wherein, communication unit 230 is electrically coupled between network N and processing unit 231.Processing unit 231 is electrically coupled between communication unit 230 and storage element 232.Storage element 232 electric property coupling processing unit 231, coding unit 233 and acquisition unit 234 respectively.The controlled computer 22 of acquisition unit 234 electric property coupling at least.In fact, processing unit 231 can be central processing unit or microprocessor, and processing unit 231 can control communication unit 230, storage element 232 and coding unit 233, but not as limit.
Communication unit 230 comprises network communication interface 2300.Network communication interface 2300 is linked up by network N and at least one master control computer 21.Storage element 232 comprises mouse event queue 2320, acquisition picture buffer 2322 and coded data buffer 2324.Storage element 232 can be storer or solid state hard disc, but not as limit.Wherein, mouse event queue 2320 electric property coupling processing unit 231, coding unit 233 and acquisition unit 234 respectively.Acquisition picture buffer 2322 electric property coupling coding unit 233 and acquisition unit 234 respectively.Coded data buffer 2324 is electrically coupled between processing unit 231 and coding unit 233.
In the time that master control computer 21 is sent to multi-computer switch 23 by network N by its mouse state information MI, the communication unit 230 of multi-computer switch 23 receives mouse state information MI by network communication interface 2300.Wherein, the mouse state information MI that master control computer 21 sends can include mouse cursor position and mouse button state.For example, mouse state information MI may include: the state (M=1) of the left button of mouse cursor position and mouse upper at coordinate (X=50, Y=25) in being pressed, but be not limited with this example.
On the one hand, processing unit 231 can directly be sent to controlled computer 22 by mouse state information MI by the mouse delivery outlet 235 on multi-computer switch 23.Then, the mouse state information MI that processing unit 231 sends master control computer 21 is temporary in after mouse event queue 2320, mouse event queue 2320 transfers mouse state information MI to a mouse state particular region instruction RI and is resent to acquisition unit 234, then by acquisition unit 234 with reference to mouse state particular region instruction RI to capture the controlled computer picture VI of controlled computer 22 from controlled computer 22.Wherein, the queue that mouse event queue 2320 is first in first out, has a finite length.In fact, mouse event queue 2320 can be a memory storage queue, but not as limit.Suppose that the length that mouse event queue 2320 has is L, one group of new mouse state information that master control computer 21 sends all can be put into the head end of mouse event queue 2320, and simultaneously remove one group of old mouse state information in the tail end of mouse event queue 2320, make the length of mouse event queue 2320 to be maintained at L constant.
And 2A-2 figure is that with the difference of 2A-1 figure: 2A-2 schemes described mouse event queue 2320 and is independently arranged at outside storage element 232, that is storage element 232 only comprises acquisition picture buffer 2322 and coded data buffer 2324.Storage element 232 can be storer or solid state hard disc, but not as limit.Wherein, mouse event queue 2320 electric property coupling processing unit 231, coding unit 233 and acquisition unit 234 respectively.Acquisition picture buffer 2322 electric property coupling coding unit 233 and acquisition unit 234 respectively.Coded data buffer 2324 is electrically coupled between processing unit 231 and coding unit 233.
Because multi-computer switch 23 can effectively shorten user in the time starting point one of master control computer 21 end operating mouses until required time between the end time of the mouse cursor of the long-range controlled computer 22 of master control computer 21 frame updatings, therefore can increase the renewal frequency of the mouse cursor of controlled computer 22.Suppose that mouse cursor moving direction DOM is for to right-hand movement, user can be as the mouse cursor of biconditional operation master control computer 21 ends (shown in the hollow mouse cursor CSR2 of 2C figure) in the time of the controlled computer 22 by master control computer 21 operating remotes delicately the mouse cursor of the controlled computer 22 of operating remote (as shown in the hollow mouse cursor CSR1 of 2B figure) to right-hand movement.
It should be noted that, the controlled computer picture VI that acquisition unit 234 captures from controlled computer 22 can be the shown whole picture (as shown in 3A figure) of controlled computer 22 or be the specific region RIR (as 3B figure as shown in) relevant with mouse cursor in the picture as shown in controlled computer 22 simultaneously, looks closely the hardware capabilities of the acquisition unit 234 in multi-computer switch 23 and determine.For example, according to the hardware design difference of acquisition unit 234, and can process the region in the shown whole picture of controlled computer 22 and/or mouse coordinates periphery certain limit partly.Because the region in mouse coordinates periphery certain limit is all regions that mouse cursor may occur, so the specific region RIR relevant with mouse cursor can comprise mouse cursor position and mouse cursor around may region in the shown picture of controlled computer 22.
In fact, specific region RIR forms according to mouse cursor position and an ad hoc rules, its range size may along with system and mousebutton state different and change, user also can set in advance.For example, ad hoc rules can refer to using mouse cursor position the specific region that (for example coordinate (X=50, Y=25)) may occur as mouse cursor for the border circular areas scope that the center of circle was formed, but not as limit.
In addition, ad hoc rules can also refer to the specific region that effective mouse cursor priority area group (effective cursor priority region set) of being combined using the mouse cursor position of effective mouse event (effective mouse event) may occur as mouse cursor.As shown in 4A figure to the 4C figure, due to from arbitrary mouse state information (X1, Y1), the time t0 that M1 is transferred into controlled computer 22 upgrades its output picture and mouse cursor is shown in to coordinate (X1 in time t1 up to controlled computer 22, Y1) and key-press status be to have poor Te of the very first time till M1, and upgrade its output picture and mouse cursor is shown in to a time event (X0 in controlled computer 22, Y0), till the coordinate of M0, have the second mistiming Tn.Therefore, stored its length of mouse cursor track of mouse event queue 2320 need be enough to allow (X1, Y1), M1 can stay in mouse event queue 2320 between the second mistiming Tn, that is at least must be included in all mouse events of the controlled computer 22 that is sent between the second mistiming Tn.Simultaneously because the mouse event that controlled computer 22 is received in poor Te of the very first time is not yet updated to picture, choose effective mouse event can be by poor very first time Te between corresponding mouse event omit.Therefore for one group of mouse event (X1, Y1), M1～(Xn, Yn), Mn, (Xn, Yn), Mn sends to controlled computer 22 and (X1, Y1) the earliest, and M1 finally sends to controlled computer 22 and falls within poor Te of the very first time, can obtain the mouse cursor position (X2 of effective mouse event, Y2) effective mouse cursor priority area group that～(Xn, Yn) combines, as shown in the mouse cursor coordinate position that thick frame enclosed in 4C figure.
Then, the controlled computer picture VI that the temporary acquisition unit 234 of acquisition picture buffer 2322 of storage element 232 captures, carries out follow-up coding for coding unit 233.When coding unit 233 receives controlled computer picture VI and in the time that mouse event queue 2320 receives mouse state particular region instruction RI from acquisition picture buffer 2322 respectively, coding unit 233 will and preferentially be encoded to the above-mentioned specific region in the controlled computer picture VI of controlled computer 22 with reference to mouse state particular region instruction RI, to produce mouse cursor coded data.
In the time that coding unit 233 produces mouse cursor coded data and is sent to coded data buffer 2324, mouse cursor coded data will be temporary in coded data buffer 2324.Then, mouse cursor coded data is sent to communication unit 230 by processing unit 231, and the network communication interface 2300 of communication unit 230 is sent to master control computer 21 by network N by mouse cursor coded data again.In the time that master control computer 21 receives mouse cursor coded data, master control computer 21 upgrades the shown master control computer picture of master control computer 21 according to mouse cursor coded data, with the mouse cursor position after display update.
It should be noted that, mouse cursor picture of the present invention, the priority of its transmission is higher than general picture, and its transmission can be by multi-computer switch 23 active push.In practical application, when master control computer 21 upgrades the shown master control computer picture of master control computer 21 according to mouse cursor coded data, mouse cursor picture and general picture can be positioned on same figure layer maybe and will be respectively mouse cursor picture and general picture be positioned on upper and lower two different figure layers.
For example, if upper figure layer is mouse cursor picture, for example directly reach by mouse event queue 2320 picture that the mouse state particular region instruction RI (needn't pass through controlled computer 22) of coding unit 233 forms, and figure below layer is general picture, for example, after the mouse state signal MI that controlled computer 22 is received by the mouse delivery outlet 235 on multi-computer switch 23 by the processing unit 231 in multi-computer switch 23, directly reached again the controlled computer picture VI of acquisition unit 234 by controlled computer 22: the nontransparent region of upper strata picture covers lower layer pictures, master control computer 21 is directly signed in upper figure layer by the mouse cursor data of renewal, and empty in old mouse cursor data with new mouse cursor data without the region of occuring simultaneously.So just can make to be finally presented on and in the picture of master control computer 21, not have two mouse cursor and occur
If mouse cursor picture is positioned at same figure layer with general picture: the region of recording in passing mouse picture when mouse cursor data that (1) master control computer 21 upgrades, when next update, can avoid mouse images position; (2) when master control computer 21 upgrades mouse cursor data, multi-computer switch 23 captures the region of mouse picture, therefore, when multi-computer switch coding 23 next time and while transmitting new mouse cursor data, can omit mouse cursor region.
Another specific embodiment according to the present invention is a kind of mouse cursor display packing.In this embodiment, mouse cursor display packing is applied to multi-computer switch.Multi-computer switch is coupled between at least one master control computer and at least one controlled computer.Multi-computer switch comprises a storage element.Please refer to the 5th figure, the 5th figure illustrates the process flow diagram of the mouse cursor display packing of this embodiment.
As shown in Figure 5, first, in step S10, the method receive mouse state information that master control computer sends and by mouse state information temporary storage in the mouse event queue of storage element.In fact, mouse state information can comprise mouse cursor position and mouse button state.The method can receive the mouse state information that master control computer sends by network or transmission line, but not as limit.
In step S11, mouse event queue transfers mouse state information to mouse state particular region instruction (RI).In step S12, the method with reference to mouse state particular region instruction (RI) to capture the controlled computer picture of controlled computer.Wherein controlled computer picture is the shown whole picture of controlled computer or only comprises the specific region relevant with mouse cursor.In fact, specific region can form according to an ad hoc rules and mouse cursor position.Specific region comprises mouse cursor position and mouse cursor around may region.In step S14, the controlled computer picture that the temporary step S12 of the method captures.
In step S16, the method is with reference to mouse state particular region instruction (RI) and preferentially mouse cursor coded data is encoded to produce in the specific region in the controlled computer picture of controlled computer, and wherein specific region is relevant with mouse cursor.In step S18, the mouse cursor coded data that the temporary step S16 of the method produces.
In step S20, mouse cursor coded data is sent to master control computer by the method.In step S22, master control computer upgrades the shown master control computer picture of master control computer according to mouse cursor coded data.
