Description

Watermark adding method, medium and device for remote desktop system

Technical Field

The embodiment of the disclosure relates to the technical field of remote desktops, in particular to a method, medium and equipment for adding watermarks for a remote desktop system.

Background

In some scenes with higher requirements on the safety of the picture content of the computer desktop, when a user shoots or captures and saves related image content, the image needs to have obvious copyright marks to protect related rights and interests, so that certain legal constraint is ensured in the propagation process of the image. A feasible method is to add a watermark mark in a desktop image, and even if a user shoots or captures a picture, the stored picture has obvious marks to identify the source, so that the user needs to carefully consider whether the use range and the mode of the picture cause legal disputes during sharing, thereby playing a certain constraint role.

In the related art, one way is that after the data is collected at the picture sending end (S end for short), watermark information is added into the data before the data is sent back to the encoder to realize the watermark function, but this method is to do a large amount of memory operations, especially if the S end has capacity to hard encode, the data collected originally can be directly sent to the hardware encoder for encoding without copy into the memory and then sent to the receiving end (R end for short), but because the watermark adding needs to be operated by using a Central Processing Unit (CPU), the collected data must be copied (copy) to the memory for operation, so that the processing performance of each frame of data is affected by three parts. After the three steps are completed, the encoding module can be sent to continue the subsequent flow, so that the frame rate of the whole remote desktop system is reduced, the influence is obvious especially on equipment with weaker S-terminal performance, and users can feel bad experiences such as picture blocking and the like under certain scenes with high frame rate requirements.

The other mode is that a full-screen transparent window program with watermark information is started along with the system at the S end and is always displayed at the top end, so that any picture displayed on the desktop is displayed under the coverage of the watermark, and the mode can achieve the effect of realizing the desktop watermark under the condition that the performance of the S end is hardly influenced. However, this approach has its drawbacks due to some limitations of the operating system or other software-induced effects: firstly, the program and daemon thereof can be maliciously stopped to run, and secondly, a login interface of the system cannot be displayed; in addition, if other programs are also on the layer on the preemption top, since the watermark window is also displayed on the preemption top, the flicker of the picture can be caused at this time, so that the picture experience is affected.

Regarding the above technical solution, the applicant has found that there is a problem that in the case of watermarking, there is a problem that the frame rate of the remote desktop system is reduced, or there is a problem that the watermark window preempts the overhead display.

Accordingly, there is a need to improve one or more problems in the related art as described above.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

There is first provided in this example embodiment a method for watermarking of a remote desktop system, as shown with reference to fig. 1, which may include the steps of:

step S101: the receiving end acquires the watermark picture and sets the watermark picture as a target watermark picture.

Step S102: and the receiving end generates a first window and displays the target watermark picture through the first window.

Step S103: the receiving end receives the coded image sent by the sending end, decodes the coded image and displays the decoded image through a second window.

Step S104: the receiving end always covers the first window on the second window.

It should be understood that, since the performance is not affected as much as possible, the watermark effect (including login interface) is ensured in the whole process after the system is started, and the phenomenon of picture flickering generated when the top is preempted due to some software is avoided. Since the remote desktop system is a remote presentation of pictures, unlike a personal PC, we can actually consider an improved way. In the remote desktop system, the real desktop runs at the S end, but a user can see that a picture is actually presented at the R end, if a sub-window always positioned at the top layer is realized in R end software, the window is transparent and has watermark information, and then some defects of directly adding the watermark at the S end can be avoided:

the watermark effect is only displayed by the R terminal processing, and the flow of the S terminal is not affected at all, so that the performance of the S terminal is not affected, and the watermark effect is not affected by the software set-top behavior of any S terminal. Because the R-terminal software can be set to display the watermark sub-window after being started and is arranged on the top layer of the software, the watermark effect can be displayed (including a system login interface) in the whole process or any time period of the whole process.

It will also be appreciated that it is necessary to ensure that the watermark picture is loaded onto the watermark mask window for display before the first frame is displayed, and that the watermark picture is updated and reloaded for display at the first time after the update is received, all after the first connection.

It is also understood that the receiving end receives the encoded image transmitted by the transmitting end. And the R end starts to decode, render and display the received image data of the S end. When the method is used for displaying, the coded image of each frame S end is presented under the shade of the watermark, so that the function of adding the watermark at the R end is achieved, any performance influence of the S end is not caused, and the R end software maintains a transparent sub-window and basically has no burden on the R end on performance.

By the method, the watermark effect is only displayed by the R terminal processing, the flow of the S terminal is not affected at all, so that the performance of the S terminal is not affected, and the watermark effect is not affected by the software set-top behavior of any S terminal.

Next, each step of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 5.

In one embodiment, referring to fig. 2, step S101 may further include:

step S201: the receiving end receives the updated watermark picture sent by the sending end and updates the target watermark picture according to the updated watermark picture.

Step S202: the receiving end displays the target watermark picture through a first window.

It is to be understood that the acquisition from the server: because each account corresponds to one S, after each account passes the verification, the server is actively acquired a corresponding watermark picture once, and when the server updates the watermark picture of the corresponding S, R connected with the current S is checked at the first time and a new watermark picture is pushed to the R to be used as a target watermark picture.

In one embodiment, referring to fig. 2, step S101 may further include:

step S203: the receiving end receives the watermark picture synchronized by the transmitting end and the server.

It should be understood that when the S terminal is powered on, the server may report the updated watermark information picture to the server, and at this time, the server may push the latest watermark information picture to the S terminal device and store the latest watermark information picture in the S terminal.

In one embodiment, step S102 may further include:

and displaying the target watermark picture as a background image of the first window.

The watermark picture is a picture with transparent background.

It should be understood that the R-side takes the watermark picture and generates a corresponding watermark sub-window (first window), the background transparent picture is displayed as the background of the sub-window (first window), the sub-window (first window) is always set as the top-level window of the R-side software, and the R-side does not process any input event, only is used for watermark masking function, and the target watermark picture is displayed.

In one embodiment, step S102 may further include:

the watermark picture is a picture in PNG format.

It should be understood that there are a variety of picture formats with transparent background, and that a PNG format picture may be used in consideration of reducing the amount of interactive data as much as possible to achieve the effect of quick interaction and satisfying the display effect.

In one embodiment, referring to fig. 2, step S101 may further include:

step S204: the receiving end selects a target sending end from the sending end list and initiates connection to the target sending end.

Step S205: and after the connection is established with the target sending end, acquiring the watermark picture from the target sending end.

It should be understood that the software is started at the R end, and the resource list of the S end is displayed after the software is started. Clicking a connection button of an S-terminal resource to connect and acquire a picture thereof. Since the watermark required by each S-terminal may be different and possibly updated, the R-terminal needs to obtain its corresponding watermark picture each time it is connected to S.

There is also provided in this example embodiment a method for watermarking of a remote desktop system, as shown with reference to fig. 3, which may include the steps of:

step S301: the method comprises the steps that a sending end generates a watermark picture corresponding to a first window and used for a receiving end to generate the first window;
