[0001] The present invention relates to the technical field of smart televisions running transplanted applications, and in particular to a transplanted application image rendering method, device and equipment based on a smart television GPU. Background Art

[0002] With the rapid development of mobile and cloud application industries, the demand for porting high-quality content to Android smart TV devices has also increased. However, even for mobile phones and TVs that use the same Android smart system, the hardware configurations vary greatly, resulting in the inability of some TV device hardware to fully run the ported high-quality APPs (which are complex to process, rich in resources, and require high computing power). For example, there may be problems such as insufficient device rendering memory and insufficient rendering computing power, resulting in the display effect presented to users being distorted, incomplete, or even black.

[0003] Therefore, when applications such as mobile APPs or cloud games are ported to smart TVs, a lot of debugging is required for the compatibility of the TV device's operating environment, and additional redesign may be required, such as but not limited to lowering the color value of the overall resources of the ported APP, reducing the size, or preparing multiple sets of resources, resulting in huge R&D time and labor costs. Summary of the invention

[0017] In at least one possible implementation manner, the image rendering method further includes:

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0038] The present invention proposes an embodiment of a transplant application image rendering method based on a smart TV GPU. Specifically, Figure 1 shown, including:

[0039] Step S1: pre-create the same second drawing board based on the original first drawing board, and split the original single rendering thread into a first thread and a second thread;

[0040] Specifically speaking, on the one hand, an identical drawing board (i.e., the second drawing board, also called the second canvas) can be additionally created for at least one drawing board (i.e., the first drawing board, also called the first canvas) pre-configured in the graphics image processor GPU by means of copying and cloning, and depth value parameters for changing the hierarchical relationship of the drawing boards can be set in both drawing boards; on the other hand, the main rendering thread of the GPU is disassembled and divided into at least two sub-threads (i.e., the first thread and the second thread), each of which performs its own function.

[0041] Step S2: the second thread loads the current resource to be rendered, and the first thread draws on the blank first drawing board;

[0042] The specific links involved in this step can be referred to as follows: based on the transplanted application instructions, the second thread loads a frame of the program to be rendered at least one frame in advance (which can be understood as a preset time unit in advance) from the running memory of the TV device, and the first thread draws the frame of image on the first drawing board (since the first drawing board is exactly the same as the second drawing board, the first drawing board is mentioned here only to represent that one of the two drawing boards can be selected). Of course, those skilled in the art can understand that when initially rendering the first frame of the picture, they can choose any one. If it is not the first frame rendering, it is drawn on the current blank drawing board, which will be explained later.

[0043] Step S3, the first thread upgrades the level of the first drawing board that has been drawn to output and display it;

[0044] In combination with the previous embodiments, the purpose of raising the level of the artboard is to make it visible to the user as an output display screen, and the way to raise the level can be achieved by adjusting the above-mentioned artboard depth value. For example, by accumulating the depth value, assuming that the currently drawn artboard is assigned 1, and then the next drawn artboard is +1, the level of the next artboard will be raised to the artboard assigned 1, and the effect of alternating output display screens can be achieved. Of course, in addition to the method of superimposing and accumulating depth values, in other embodiments of the present invention, a depth value modulation mechanism of clearing and resetting can also be used, which will be explained below.

[0045] Step S4: the first thread draws the next resource to be rendered loaded by the second thread on a blank second drawing board, and the second thread clears the first drawing board to make it blank;

[0046] It can be seen that the aforementioned first thread and second thread have a clear division of labor. In this embodiment, the first thread is only responsible for drawing the picture to be rendered on a blank canvas and upgrading the completed canvas to display it in front of the user; the responsibility of the second thread is to load the picture resources to be rendered from the running memory according to the program design and to clear and reset the canvas after rendering and display.

[0047] As for resetting, the present invention proposes, based on this concept, that in other embodiments, a depth value modulation mechanism of clearing and resetting can also be adopted: the second thread "cleans" the depth value of the drawing board while performing the drawing board clearing task, that is, the action of clearing the drawing board includes resetting the depth value of the drawing board to the initial value (such as 0). Since the depth value of this drawing board is restored to the initial value, this drawing board will be dropped from the upper layer to the lower layer and will no longer be output and displayed to the user. This state can be understood as the cleared blank drawing board is currently under the drawing board that is output and displayed in the upper layer, and is ready for the first thread to draw the next frame. For example, the first thread no longer performs the task of raising the drawing board level by superimposing the value, but is similar to setting the depth value of the completed drawing board from 0 to 1; while the second thread sets the depth value of the cleared drawing board from 1 to 0 when clearing the drawing board.

[0048] It can be seen that in the embodiment of the reset mechanism, the responsibility of the second thread can be considered to be an additional task compared to the embodiment mentioned above, namely, resetting the depth value; and in actual operation, this additional task can be included in "clearing the drawing board".

[0049] Step S5, the first thread upgrades the level of the second drawing board that has been drawn to output and display it, and draws the first drawing board that has been cleared to a blank state based on the next resource to be rendered loaded by the second thread;

[0050] The first thread and the second thread use the first drawing board and the second drawing board alternately and cyclically perform loading, drawing, and clearing tasks according to the above steps to complete the image rendering processing of the transplanted application.

[0051] Finally, it can be added that in addition to alternately and cyclically executing the loading, drawing, and clearing tasks, the dynamic adjustment of the depth value of each artboard is also a key task proposed by the present invention, because the adjustment of the depth value is directly related to the picture effect presented to the user. Therefore, in other preferred embodiments of the present invention, the following measures are also included:

[0052] Based on different resources to be rendered, while the second thread is loading the current resource to be rendered, setting a corresponding drawing duration threshold;

[0053] When the first thread is drawing the current resource to be rendered, if the drawing is not completed after reaching the drawing time threshold, the second thread will clear the current output display board and force its depth value to remain unchanged until the first thread completes the current drawing task. This is because in real scenes, the processing time of the above process and the drawing time threshold are relatively short compared to the recognition ability of the human eye. It is difficult for the human eye to capture that the upper display board is cleared to a blank state during this process. The process of clearing first and then descending can reserve more drawing filling time for the first thread.

[0054] In summary, the main design concept of the present invention is to provide an optimization solution for the problem that high-quality applications on mobile phones and the cloud cannot run smoothly on TV devices due to their large resources, resulting in high rendering computing power required during operation. Specifically, at least two drawing boards are pre-built and the original main rendering thread is split into at least two threads, one of which is responsible for loading the resources to be rendered and cleaning the contents of the displayed drawing board, and the other thread is focused on filling the resources to be rendered on each drawing board in order. In this process, the depth value of each drawing board is dynamically adjusted to change the hierarchical relationship, so that the upper drawing board displays the completed content, and the lower drawing board draws the next content, thereby cyclically executing the loading, drawing, and cleaning tasks to complete the image rendering processing of the transplanted application. The mechanism of the present invention is to reduce memory data and convert it into video memory data, and then rotate the drawing board through multi-threaded parallel collaboration, reduce the rendering computing power requirements of the graphics image processor of the TV device, and effectively avoid the situation of abnormal display of the picture, so that high-quality transplanted applications can run smoothly on the TV side.

[0055] Corresponding to the above embodiments and preferred solutions, the present invention also provides an embodiment of a transplant application image rendering device based on a smart TV GPU, such as Figure 2 As shown, it may specifically include the following components:

[0056] A GPU pre-configuration module 201, configured to pre-create an identical second drawing board based on the original first drawing board, and split the original single rendering thread into a first thread and a second thread;

[0057] The multi-threaded multi-drawing board alternating rendering module 202 is used to perform the following:

[0058] The second thread loads the current resource to be rendered, and the first thread draws on the blank first drawing board;

[0059] The first thread upgrades the level of the first drawing board after drawing to output and display;

[0060] The first thread draws the next resource to be rendered loaded by the second thread on a blank second drawing board, and the second thread clears the first drawing board to make it blank;

[0061] The first thread upgrades the level of the second drawing board that has been drawn to output and display it, and draws the first drawing board that has been cleared to a blank state based on the next resource to be rendered loaded by the second thread;

[0062] The first thread and the second thread use the first drawing board and the second drawing board alternately and cyclically perform loading, drawing, and clearing tasks according to the above steps to complete the image rendering processing of the transplanted application.
