Abstract
The present invention relates to a kind of lossless automatic switching method that damages for RDP, the method comprises the steps: the picture pace of change on (1) monitoring remote desktop and runs process accordingly；(2) judge on remote desktop, whether picture pace of change exceedes setting value, if the process coding schedule of operation process with preservation is contrasted, perform step (3), otherwise perform step (4)；(3) judge whether operation process corresponds to damage process in process coding schedule, if the image content then on remote desktop carries out coding output by lossy coding mode, otherwise perform step (4)；(4) image content on remote desktop is carried out coding output by lossy coding mode.Compared with prior art, the present invention uses the method that pace of change detects and process detection combines of picture region of variation to judge to use lossless or lossy coding, improves the accuracy of judgement, improves Consumer's Experience.
Description
Technical field
The present invention relates to a kind of lossless damage automatic switching method, especially relate to a kind of nothing for RDP
Damage damages automatic switching method.
Background technology
RDP is the screen updates of remote desktop to be sent to subscription client show, optimal in order to ensure
Consumer's Experience, when subscription client shows, needs take different type of codings according to the difference of screen content type,
Type of coding includes lossy coding and lossless coding.Such as with AutoCAD, when PhotoShop etc. should be used as design, need
Full reduction remote desktop screen content, it is therefore desirable to use lossless coding, and the office application that other enable such as Office applies
Time, use damage or lossless coding can, and when playing video or change game picture quickly, it is necessary to use and have
Damage coding and reduce the transmission bandwidth of data, it is ensured that the smooth display of video class picture.
The scheme that prior art uses mainly judges whether to damage still according to the pace of change of screen area
Lossless coding, this mode is not necessarily accurate, such as can be switched to damage mode when IE browser is quickly by mouse rollovers, but
Being that now user may not want that and sees the mode damaged, Consumer's Experience is poor.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of for remote desktop
The lossless of agreement damages automatic switching method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of lossless automatic switching method that damages for RDP, the method comprises the steps:
(1) monitor the picture pace of change on remote desktop and run process accordingly；
(2) judge on remote desktop, whether picture pace of change exceedes setting value, if entering operation process and preservation
Journey coding schedule contrasts, and performs step (3), otherwise performs step (4)；
(3) judge whether operation process corresponds to damage process in process coding schedule, if the picture then on remote desktop
Face content carries out coding output by lossy coding mode, otherwise performs step (4)；
(4) image content on remote desktop is carried out coding output by lossy coding mode.
The picture pace of change of step (1) medium-long range desktop obtains in the following way: in real time on monitoring remote desktop
Picture changes, and is outlined by region of variation one rectangle frame that can comprise whole region of variation of employing when picture changes, with
Time detect the size of this rectangle frame, the size leukorrhagia of this rectangle frame and correspondence stores to historical queue, by one
The overall size size of the rectangle frame of storage in interior historical queue of fixing time obtains picture pace of change.
Operation process on step (1) medium-long range desktop is monitored by Hook Function.
The described picture change on monitoring remote desktop used Hook Function to be monitored.
Described process coding schedule includes the type of coding of process title and correspondence, and described type of coding includes damaging
Process and lossless process.
Compared with prior art, present invention have the advantage that
(1) present invention use the pace of change detection of picture region of variation and the method that combines of process detection judge be
Use lossless or lossy coding, improve the accuracy of judgement, improve Consumer's Experience；
(2) detection of the picture pace of change of remote desktop of the present invention is by the picture region of variation in the detection setting time
Size obtain, when in the setting time, the overall size size of picture region of variation is bigger, then picture pace of change is relatively
Hurry up, this mode is convenient to be realized.
Accompanying drawing explanation
Fig. 1 is the present invention lossless FB(flow block) damaging automatic switching method for RDP.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of lossless automatic switching method that damages for RDP, the method comprises the steps:
(1) monitor the picture pace of change on remote desktop and run process accordingly, this step passes through Hook Function
Realize the monitoring of operation process；
(2) judge on remote desktop, whether picture pace of change exceedes setting value, if entering operation process and preservation
Journey coding schedule contrasts, and performs step (3), otherwise performs step (4), and wherein process coding schedule includes process title and right
The type of coding answered, described type of coding includes the process that damages and lossless process；
(3) judge whether operation process corresponds to damage process in process coding schedule, if the picture then on remote desktop
Face content carries out coding output by lossy coding mode, otherwise performs step (4)；
(4) image content on remote desktop is carried out coding output by lossy coding mode.
Wherein, the picture pace of change of step (1) medium-long range desktop obtains in the following way: real-time by Hook Function
Picture change on monitoring remote desktop, can comprise whole region of variation when picture changes by region of variation employing one
Rectangle frame outline, detect the size of this rectangle frame simultaneously, the size leukorrhagia of this rectangle frame and correspondence stores to going through
In history queue, obtain picture pace of change by the overall size size of the rectangle frame of storage in historical queue in certain time.
The detection of the picture pace of change of remote desktop of the present invention is by the picture region of variation in the detection setting time
Size obtains, and when in the setting time, the overall size size of picture region of variation is bigger, then picture pace of change is very fast,
This mode is convenient to be realized.
Specifically, the present invention damage automatic switching method flow chart as shown in Figure 1 for the lossless of RDP:
Perform step 1: monitor the picture on remote desktop, perform step 2；
Step 2: monitoring operation process, performs step 3；
Step 3: be loaded on remote desktop by process coding schedule, performs step 4；
Step 4: detect that the picture change on remote desktop performs step 5；
Step 5: region of variation one rectangle frame that can comprise whole region of variation of employing is outlined, detects this square simultaneously
The size of shape frame, the size leukorrhagia of this rectangle frame and correspondence stores to historical queue, performs step 6；
Step 6: obtaining the rectangle frame in the setting time from historical queue, what each rectangle frame represented is region of variation,
Judge that the overall size size of all rectangle frames, whether more than setting value, if then performing step 7, otherwise performs step 9；This step
The judgement of the 6 picture paces of change i.e. achieving remote desktop；
Step 7: judge that in step 2, the current process of monitoring, whether for damaging process, if being carried out step 8, otherwise performs
Step 9；
Step 8: the image content on remote desktop is carried out coding output by lossy coding mode, performs step 10；
Step 9: the image content on remote desktop is carried out coding output by lossless coding mode, performs step 10；
Step 10: judged whether remote transmission, if then terminating, otherwise returns step 4.
