Abstract

The present invention discloses a method, device and equipment for rendering images of transplanted application programs based on the GPU of a smart TV, relating to the technical field of running transplanted application programs on a smart TV. Specifically, two drawing boards are pre-constructed and the original main rendering thread is split into two threads. One thread is responsible for loading resources to be rendered and clearing the displayed drawing boards, and the other thread focuses on sequentially filling the resources to be rendered on each drawing board. During this process, the depth values of the drawing boards are dynamically adjusted to change the hierarchical relationship, so that the upper drawing board displays the rendered content and the lower drawing board performs the drawing of the next content. Thus, the tasks of loading, drawing and clearing are cyclically executed to complete the image rendering process of the transplanted application program. By parallel cooperation of multiple threads and rotation of the hierarchical levels of the drawing boards, the present invention reduces the rendering computing power requirements for the graphics image processor of the TV device, effectively avoiding the abnormal display of the screen, and thus enabling high-quality transplanted application programs to run smoothly on the TV side.

Description

Technical Field

[0001] The present invention relates to the technical field of running transplanted application programs on smart TVs, and in particular, to a method, device, and equipment for rendering images of transplanted application programs based on the GPU of a smart TV. Background Art

[0002] The mobile and cloud application industries have developed rapidly, and the demand for transplanting high-quality content to Android smart TV devices has also increased accordingly. However, even though the mobile and TV sides are both Android smart systems, there are significant differences in hardware configurations, resulting in some TV device hardware being unable to fully run the transplanted high-quality APPs (which are complex to process, resource-rich, and require high computing power). For example, there are problems such as less rendering memory and insufficient rendering computing power on the device, and the display effects presented to users will show screen distortion, incomplete images, or even black screens.

[0003] Therefore, currently, when transplanting application programs such as mobile APPs or cloud games to smart TVs, a large amount of debugging is still required for the compatibility of the TV device's operating environment, and additional redesign may also be necessary. For example, but not limited to, reducing the color values of the overall resources of the transplanted APP, reducing the size, or preparing multiple sets of resources, resulting in extremely high R & D time and labor costs. Summary of the Invention

[0004] In view of the above, the present invention aims to provide a method, device, and equipment for rendering images of transplanted application programs based on the GPU of a smart TV, so as to solve the high cost problem of transplanting mobile or cloud application programs to smart TVs, and improve the success rate of running transplanted application programs on smart TV models.

[0005] The technical solution adopted by the present invention is as follows:

[0006] In a first aspect, the present invention provides a method for rendering images of transplanted application programs based on the GPU of a smart TV, which includes:

[0007] 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;

[0008] The second thread loads the currently to-be-rendered resource, and the first thread draws on the blank first drawing board;

[0009] The first thread raises the level of the drawn first drawing board and outputs it for display;

[0010] The first thread draws the next to-be-rendered resource loaded by the second thread on the blank second drawing board, and the second thread clears the first drawing board to make it blank;

[0011] The first thread raises the level of the second drawing board that has been drawn and outputs it for display, and based on the next resource to be rendered loaded by the second thread, draws the first drawing board that has been cleared to a blank state;

[0012] The first thread and the second thread alternately and circularly execute the tasks of loading, drawing, and clearing by using the first drawing board and the second drawing board according to the above steps to complete the image rendering process of the ported application.

[0013] In at least one possible implementation manner, the method for creating the second drawing board includes: copying the pre-configured first drawing board to obtain the second drawing board, and both drawing boards include depth values for changing the level of the drawing board.

[0014] In at least one possible implementation manner, the method for dynamically adjusting the level of the drawing board includes: assigning a value to the depth value of the currently drawn drawing board by accumulating numerical values.

[0015] In at least one possible implementation manner, the method for dynamically adjusting the level of the drawing board further includes: by resetting the numerical value, restoring the depth value of the cleared drawing board to the initial value while or after clearing the drawing board.

[0016] In at least one possible implementation manner, the second thread loads the currently to-be-rendered resource, and the first thread draws on the blank first drawing board, specifically including: based on the transplanted application instructions, the second thread pre-loads the currently to-be-rendered resource from the operating memory of the TV, and then the first thread draws the currently to-be-rendered resource on the first drawing board according to the application instructions.

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

[0018] Based on different resources to be rendered, while the second thread loads the currently to-be-rendered resource, set the corresponding drawing duration threshold;

[0019] When the first thread draws the currently to-be-rendered resource, if the drawing is not completed when the drawing duration threshold is reached, the second thread clears the currently output display drawing board and forces its depth value to remain unchanged until the first thread completes the current drawing task.

[0020] In a second aspect, the present invention provides a ported application image rendering device based on an intelligent TV GPU, which includes:

[0021] A GPU pre-configuration module, configured to 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;

[0024] The first thread raises the level of the completed first drawing board for output display;

[0025] The first thread draws the next to-be-rendered resource loaded by the second thread on the blank second drawing board, and the second thread clears the first drawing board to make it blank;

[0026] The first thread raises the level of the completed second drawing board for output display, and based on the next to-be-rendered resource loaded by the second thread, draws on the first drawing board that has been cleared to be blank;

[0027] The first thread and the second thread alternately and circularly execute loading, drawing, and clearing tasks using the first drawing board and the second drawing board according to the above steps to complete the image rendering process of the transplanted application.

[0030] In a fifth aspect, the present invention further provides a computer program product. When the computer program product is executed by a computer, it is used to execute the method as described in the first aspect or any possible implementation manner of the first aspect. In a possible design of the fifth aspect, the relevant programs involved in this product can be stored in whole or in part in the memory packaged together with the processor, or can be stored in whole or in part in a storage medium not packaged together with the processor.

[0031] It should be understood that the technical solutions of the second to fifth aspects of the embodiments of the present application are consistent with those of the first aspect of the embodiments of the present application. The beneficial effects obtained by each aspect and the corresponding feasible implementation manners are similar and will not be repeated.

[0032] The main design concept of the present invention is to provide an optimization solution for the problem that high-quality application programs on the mobile phone side and cloud side 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-constructed and the original main rendering thread is split into at least two threads. One thread is responsible for loading the resources to be rendered and clearing the content of the displayed drawing board, and the other thread focuses on sequentially filling the resources to be rendered on each drawing board. During this process, the depth values of each drawing board are dynamically adjusted to change the hierarchical relationship, so that the drawing board on the top displays the completed drawn content, and the drawing board on the bottom performs the drawing of the next content. Thus, the tasks of loading, drawing, and clearing are cyclically executed to complete the image rendering process of the transplanted application program. The mechanism of the present invention is to reduce the memory data and convert it into video memory data, and then through multi-threaded parallel cooperation and rotation of the drawing board levels, reduce the rendering computing power requirements for the graphics processing unit of the TV device, effectively avoiding the abnormal display of the screen. Therefore, high-quality transplanted application programs can run smoothly on the TV side. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0038] The present invention proposes an embodiment of a method for rendering images of a transplanted application program based on an intelligent TV GPU. Specifically, as Figure 1 shown, which includes:

[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 regarding this step, on the one hand, by means of replication and cloning, an additional identical drawing board (i.e., the second drawing board, also referred to as the second canvas) can be created for at least one pre-configured drawing board (i.e., the first drawing board, also referred to as the first canvas) in the graphics processing unit (GPU), and a depth value parameter 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, that is, handed over to at least two sub-threads (i.e., the first thread and the second thread) to perform their respective duties.

[0041] Step S2: The second thread loads the currently to-be-rendered resource, and the first thread performs drawing 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 at least one frame (which can be understood as a pre-set time unit) in advance from the operating memory of the television device into the frame of the program currently to be rendered, and the first thread draws this frame of image on the first drawing board (since the first drawing board and the second drawing board are exactly the same, the mention of the first drawing board here is only to represent choosing one of the two drawing boards). Of course, those skilled in the art can understand that when initially rendering the first frame of the image, it can be chosen arbitrarily. If it is not the first frame rendering, it is drawn on the current blank drawing board, which will be described later.

[0043] Step S3: The first thread promotes the hierarchical level of the drawn first drawing board and outputs it for display.

[0044] Combined with the previous embodiments, the purpose of promoting the hierarchical level of the drawing board is to make it the output display screen visible to the user, and the way to promote the hierarchical level can be achieved by adjusting the above-mentioned depth value of the drawing board. For example, by accumulating the depth value, assuming that the currently drawn drawing board is assigned 1, and then for the next drawn drawing board, +1 is added, then the hierarchical level of the next drawing board will be promoted above the drawing board assigned 1, and the function of alternately outputting and displaying the screen can be achieved. Of course, in addition to the way of accumulating the depth value, in other embodiments of the present invention, a depth value modulation mechanism of clearing and resetting can also be adopted, which will be described later.

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

[0046] It can be seen from this that the aforementioned first thread and the second thread have clear divisions of labor. In this embodiment, the first thread is only responsible for drawing the to-be-rendered image on the blank drawing board and promoting the hierarchical level of the drawn drawing board to display it in front of the user; while the responsibility of the second thread is to load the image resources to be rendered from the operating memory according to the program design and to clear and reset the drawing board after rendering and displaying.

[0047] Regarding reset, based on this concept, the present invention proposes that in some other embodiments, a depth value modulation mechanism of clearing and resetting can also be adopted: while the second thread is performing the drawing board cleaning task, it also "cleans" the depth value of the drawing board, that is, the action of cleaning 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 drop from the upper layer to the lower layer and no longer be output and displayed to the user. This state can be understood as that the cleared blank drawing board is below the drawing board that is currently being output and displayed at the upper layer and is ready for the first thread to draw the next frame of the picture. For example, when the first thread performs the task of promoting the drawing board level, it no longer adds values, but is similar to setting the depth value of the drawn drawing board from 0 to 1; while the second thread sets the depth value of the cleared drawing board from 1 to 0 when cleaning the drawing board.

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

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

[0050] The first thread and the second thread alternately and circularly execute the loading, drawing, and cleaning tasks using the first drawing board and the second drawing board according to the above steps to complete the image rendering process of the ported application program.

[0051] Finally, it can be added that in addition to alternately and circularly executing the loading, drawing, and cleaning tasks, the dynamic adjustment of the depth value of each drawing board 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 some 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 loads the current resource to be rendered, set the corresponding drawing duration threshold;

[0053] When the first thread is rendering the currently to-be-rendered resource, if the rendering duration threshold is reached and the rendering is not completed yet, the second thread clears the currently output display drawing board and forces its depth value to remain unchanged until the first thread completes the current rendering task. This is considering that in the real scenario, the processing time of the above process and the rendering duration threshold are relatively short compared to the human eye recognition ability, and it is difficult for the human eye to capture that the drawing board displayed on the upper layer is cleared to a blank state during this process. And just this process of clearing first and then lowering the layer can reserve more rendering and 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 application programs on mobile phones and the cloud have large resources, resulting in high rendering computing power required during operation and unable to run smoothly on TV devices. Specifically, at least two drawing boards are pre-constructed and the original main rendering thread is split into at least two threads. One thread is responsible for loading the to-be-rendered resource and clearing the content of the already displayed drawing board, and the other thread focuses on sequentially filling the to-be-rendered resource on each drawing board. During this process, the depth values of each drawing board are dynamically adjusted to change the hierarchical relationship, so that the drawing board on the upper layer displays the completed drawn content, and the drawing board on the lower layer performs the drawing of the next content. Thus, the tasks of loading, drawing, and clearing are cyclically executed to complete the image rendering process of the transplanted application program. The mechanism of the present invention is to reduce memory data and convert it into video memory data, and then rotate the drawing boards through multi-threaded parallel cooperation, reducing the rendering computing power requirements for the graphics image processor of the TV device, effectively avoiding the abnormal display of the screen, and thus enabling high-quality transplanted application programs to run smoothly on the TV side.

[0055] Corresponding to the above-mentioned various embodiments and preferred solutions, the present invention also provides an embodiment of an image rendering device for transplanted application programs based on the GPU of a smart TV, as Figure 2 shown, which may specifically include the following components:

[0056] The GPU pre-configuration module 201 is used to 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;

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

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

[0059] The first thread raises the level of the drawn first drawing board for output 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 in a blank state;

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

[0062] The first thread and the second thread alternately and circularly execute loading, drawing, and clearing tasks using the first drawing board and the second drawing board according to the above steps to complete the image rendering process of the ported application.

[0063] It should be understood that the division of each component in the above Figure 2 ported application image rendering device based on the smart TV GPU is only a division of logical functions.
