The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The screen of a digital TV is mainly composed of a video layer picture and an interface layer picture. The video layer refers to the frame picture displayed by the on-board hardware analysis of the video stream of the digital TV network, that is, the TV picture viewed by the user; the interface layer refers to the picture displayed by the on-board software after parsing the user interface, and the interface layer The data includes a function table, a navigation bar, a prompt information, a user input, a two-dimensional special effect, etc., and for a digital TV browser software, generally refers to a webpage, and the two-dimensional graphic special effect mentioned in the embodiment of the present invention is The 2D effect is displayed on the interface layer webpage.

Usually, the digital signal processor used in the set-top box comes with a simplified version of the 2D graphics acceleration device, such as ST's STi51XX series, comes with AGE (Append Graphics Engine); BroadCom's 974XX series, comes with GSB (Graphics SubBlock); LSI's SC20XX series, comes with BGE (Block Graphics Engine); Huawei HISI 3XXX series, comes with TDE (Two Dimension Engine); Intel's CE21XX series, comes with 2DA (2D Accelerater). These self-contained acceleration devices are not really meaningful graphics acceleration devices because they lack basic graphics decoding functions, such as drawing graphics functions, graphics scaling functions, etc., but only simple block data movement, transparency overlay, raster operation. Such functions, so called the simplified version of the 2D graphics acceleration device.

The embodiment of the present invention is to fully utilize the two-dimensional graphics acceleration device that the digital signal processor used by the set-top box is not powerful, and to reduce the two-dimensional graphic special effects through the optimization and improvement of the software algorithm. Achieve the occupancy and performance requirements of the on-board digital signal processor. Smoothly implement two-dimensional graphics on a set-top digital signal processor with a computing power of 80M mips and a simplified version of the two-dimensional graphics acceleration device. Basic effects display.

Referring to FIG. 1 in detail, FIG. 1 is a schematic flow chart of a method according to a first embodiment of the present invention.

Step 101: Determine the size and position of the source object graphics that are respectively subjected to the two-dimensional effect processing by the digital signal processor and the two-dimensional graphics acceleration device.

The two-dimensional graphics acceleration device is self-contained with a digital signal processor, and has only simple functions of block data shifting, transparency superposition, and raster operation.

Performing 2D special effects refers to replacing or superimposing multiple 2D images (two or more) according to different rules to form two-dimensional graphic effects, such as 24 kinds of shutter effects, transparent fade-out effects, filter effects, etc. You can also extend animation effects (motion of 2D objects) and raster effects.

The data of the superimposed mixed image using the digital signal processor and the data of the superimposed mixed image of the two-dimensional graphics acceleration device provided by the digital signal processor may be pre-acquired to form a performance database, and the performance database is mainly composed of the foregoing two The size of the area in which the device handles the picture effects and the time required to implement the picture effects respectively.

According to the source object graphic size and the performance database, it is reasonable to arrange which source object graphics are processed by the digital signal processor, which source object graphics are completed by the two-dimensional graphics acceleration device, or a complete source object graphics can be cut into In part, one part is processed by the digital signal processor, and the other part is completed by the two-dimensional graphics acceleration device, so that the two devices share the work of the two-dimensional special effect processing, and the respective processing parts are completed in the same time period, thereby achieving a balance burden. The optimization effect of shortening the graphics processing time.

The source object graphic can be divided into two or more partial graphics. Taking two parts as an example, the specific size of the two parts is the two sizes recorded in the performance database. The principle of selection is that the two devices process two parts of the object separately for less than two devices. The time when any one of the devices processes the full-size source object graph separately, and the processing time of the two devices is not much different or even equal.

For example, the size of the source object is A*B. According to the performance database, the digital signal processor needs to process N1 seconds for the A1*B size. The 2D graphics acceleration device needs to process the A2*B size for N2 seconds. +A2=A, N1 and N2 are both less than the time of processing the A*B-sized source object graph by either of the digital signal processor and the two-dimensional graphics acceleration device, and N1 and N2 are not much different or even equal. When N1 and N2 are equal, the digital signal processor and the two-dimensional graphics acceleration device simultaneously perform two-dimensional special effect processing on a part of the source object graphics, so that resource sharing optimization is most efficient.

Obviously, the source object graphic can be cut into two or more parts according to actual conditions, for example, three, four or more parts, which does not affect the implementation of the embodiment of the present invention, as long as the graphic processing time after cutting is satisfied. The time to process a complete graphic on a single device is fine.

Step 102: Send the size, location, and acquired special effect parameters of the source object graphic to the digital signal processor, and add the processing object identifier to the parameters of the source object graphic determined by the two-dimensional graphics acceleration device.

The processing object identifier may be a certain parameter or a special assignment, and does not affect the implementation of the embodiment of the present invention.

Step 103: The digital signal processor sends the size, location, and special effect parameters of the source object graphic to which the processing object identifier is added to the two-dimensional graphics acceleration device.

The digital signal processor and the two-dimensional graphics acceleration device are coordinated by a set of registers, which can be divided into two types: a command parameter register and a running status register.

For example, when a two-dimensional graphics acceleration device is required to perform an overlay mixing task, the digital signal processor writes the corresponding commands and parameters into the command parameter register (group), and the two-dimensional graphics acceleration device reads from the command parameter register (group). And will perform the overlay mixing task and write the state of the overlay mixing to the status register. At the end of the overlay blending, the two-dimensional graphics acceleration device writes the superimposed state to the status register, and the digital signal processor queries the status register. Get 2D graphics to accelerate device status.

After the two-dimensional graphics acceleration device acquires the graphic position and the special effect parameter of the source object of the processing object identification, according to the special effect parameter, the corresponding special effect display effect is completed in the display memory space, the target object graphic is formed, and the target object graphic is output to the display screen. .

Preferably, the two-dimensional graphics acceleration device can complete the corresponding special effect display effect in the display memory space by using a set of standard two-dimensional special effects transplantation interface function according to the special effect parameter. A set of standard 2D special effects porting interface functions may include: block shift function, rectangular fill function, allocation of two-dimensional frame space interface function, release of two-dimensional frame space interface function, and acquisition of asynchronous execution state interface function. The 2D effect porting interface function can be easily ported to a set-top box or other handheld digital device with a digital signal processor with a 2D graphics acceleration device as its core device, such as a mobile phone or a personal digital assistant (PDA, Personal). Digital Assistant), etc., for various devices to perform 2D effects processing.

In the embodiment of the present invention, the processing of the two-dimensional graphic special effect display of the source object graphic is distributed to the digital signal processor and the two-dimensional graphics acceleration device of the digital signal processor, and the processing speed of the graphic is high due to the two-dimensional graphics acceleration device. In the digital signal processor, most of the processing work of the two-dimensional graphics effect display is completed by the two-dimensional graphics acceleration device in the display memory space, which reduces the occupancy and performance requirements of the digital signal processor.

The following second embodiment is a detailed description of the application of the first embodiment in a practical application scenario, where the source object graphic is 640*480 size, and the graphic is cut into two parts as an example.

Referring to FIG. 2 in detail, FIG. 2 is a schematic flow chart of a method according to a second embodiment of the present invention.

Step 201: Record the time required for the digital signal processor and the two-dimensional graphics acceleration device to respectively process the graphic objects of the plurality of sizes.

The size and time correspondence can be recorded in a table, as shown in Table 1:

It can be seen from Table 1 that when the object graphics are of various sizes, the digital signal processor and the two-dimensional graphics acceleration device separately process the time required for the object graphics of the size, for example, the digital signal processor separately processes the 636*480 size graphics. The time is 254ms.

Step 202: Determine the size and position of the source object graphic processed by the digital signal processor and the two-dimensional graphics acceleration device respectively, and cut the source object graphic into two parts.

It can be seen from Table 1 that when the source object graphic is 640*480 size, the time required for the digital signal processor to process the full-size source object graphic separately is 260 ms, and the two-dimensional graphics acceleration device separately processes the full-size source object graphic. The time required is 6ms; the time for the digital signal processor to process 4*480 size graphics is 5ms, and the time for the 2D graphics acceleration device to process 636*480 size graphics is also 5ms, and the 4*480 size is added to the 636*480 size. Just 640*480 size, the required time for both sizes is less than the time required to process the full-size source object graphic separately. Therefore, it can be determined that the source object pattern of 640*480 size is cut into two parts A and B, and the part A is 4*480 size, which is handed to the digital signal processor to process the two-dimensional graphic special effect, and the part B is 636*480 size. , handed over to the 2D graphics acceleration device to handle 2D graphics effects.

Referring to FIG. 3, FIG. 3 is a schematic view showing the cutting position of the source object pattern in the second embodiment of the present invention, FIG. 3a is a schematic view of a cutting mode, and FIG. 3b is a schematic view showing another cutting mode. The position refers to the portion where the A portion of the 4*480 size is the upper portion, the portion B of the 636*480 size is the lower portion, as shown in Fig. 3a, or the portion A of the 4*480 size is the lower portion. The portion of the 636*480 size B portion is the upper portion, as shown in Fig. 3b, which does not affect the implementation of the embodiment of the present invention.

Step 203: Send the cut size, the position, and the acquired special effect parameter of the source object graphic to the digital signal processor, and add the processed object identifier to the source object graphic parameter determined by the two-dimensional graphics acceleration device.

For example, the code obtained from a web page is:

META http-equiv=Page-Enter content=revealTrans(Duration=5.0, Transition=3)

Indicates that the required 2D effect display effect is the louver effect numbered 3, and the continuous effect time is 5 seconds.

The source object graphic is cut into two parts: the A part of the 4*480 size is the upper part, the B part of the 636*480 size is the lower part, the special effect type is the louver effect, the special effect number is 3, and the special effect continues. These parameters are sent to the digital signal processor for a time of 5 seconds, and the processing object identification is added to the B part graphic parameters.

Obviously, the relationship between the effect number and the corresponding effect type can be customized. The operator can add a custom 2D effect type and its effect number, and store the effect number and the customized 2D effect type on the set-top box. The corresponding relationship can be; for example, if a new number of louver effects is added, a new special effect number needs to be expanded, and the correspondence between the new special effect number and the new louver effect is stored on the set-top box. In this way, operators can freely create a variety of 2D special effects types, such as movie poster backgrounds, recent popular episode backgrounds or other new types of image transformation methods, to attract more users.

Step 204: The digital signal processor sends the size, location, and special effect parameters of the source object graphic to which the processing object identifier is added to the two-dimensional graphics acceleration device.

The digital signal processor can write the size, position and special effect parameters of the B part of the graphic into the command parameter register, so that the two-dimensional graphics acceleration device reads the size, position and special effect parameters of the B part graphic from the command parameter register, so that Process it.

Step 205: The two-dimensional graphics acceleration device acquires the size, the position, and the special effect parameter of the image of the source object object to which the processing object identifier is added, and the special effect parameter includes the special effect type number, the special effect duration, and the like.

Step 206: The two-dimensional graphics acceleration device completes the corresponding special effect display effect in the display memory space according to the special effect parameter, and forms the target object graphic.

For example, the two-dimensional graphics acceleration device superimposes the special effect display effect corresponding to the special effect type code on the position of the source object graphic to obtain the target object graphic; wherein, the source object graphic occupies a space for displaying one frame of the memory, and the target object graphic occupation display The space of one frame of memory.

Two-dimensional graphics acceleration devices usually operate directly on physical addresses. The hardware feature requires two to three similar frame-like operating spaces for operation. The screen display on the set-top box must have a frame space, the memory space is regarded as the final output of the two-dimensional graphics acceleration device (target object graphics), and the two-dimensional graphics acceleration device needs to be allocated two frame space sources. And source 2, in general, the three frame spaces are given according to the maximum width and height of the screen. The physical address of the three frame spaces does not change during the running of the program, but the superimposed mixed small The location of the area is subject to change.

Referring to Fig. 4, Fig. 4 is a schematic view showing the superimposed area of the second embodiment of the present invention. 4a and 4b are frame space source 1 and source 2, and FIG. 4c is a target object pattern, and the oblique line portions in FIG. 4a, FIG. 4b, and FIG. 4c are areas where two-dimensional effect processing is required. Generally, the source 1 width, the source 2 width, and the target width are the maximum width of the display screen, and the source 1 height, the source 2 height, and the target height are the maximum heights of the display screen, in the 4th, 4b, and 4c pictures. The height and width of the shaded portion are the same, the longitudinal offset 1 in Fig. 4a is equal to the longitudinal offset 2 in Fig. 4b, and the lateral offset 1 in Fig. 4a is equal to the lateral offset 2 in Fig. 4b, and the The longitudinal offset 3 in Fig. 4c is not necessarily equal to the longitudinal offset 1 in Fig. 4a, and the lateral offset 3 in Fig. 4c is not necessarily equal to the lateral offset 1 in Fig. 4a, obviously, in Fig. 4c The longitudinal offset and the longitudinal offset are equal to or not equal to the values in FIGS. 4a and 4b, or the longitudinal offset 3 and the lateral offset 3 in FIG. 4c are fixed values or change values, and do not affect the present invention. The implementation of the embodiment can realize various display forms of the two-dimensional special effect, giving the user rich visual enjoyment.

Thus, in the embodiment of the present invention, only a memory space of up to 3 frames full screen (including the display memory) can be used to complete various two-dimensional graphics effects, and the existing method requires a large amount of memory resources. (6 to 10 frames of full screen memory space), the embodiment of the invention greatly reduces the occupied memory space. Moreover, the embodiment of the present invention uses a digital signal processor and a two-dimensional graphics acceleration device to simultaneously perform two-dimensional special effect processing of the source object graphics, so that the occupancy rate of the digital signal processor is reduced from 80 to 95% to 2 to 10 in the processing. %; also improved the speed of 2D effects processing. For example, the embodiment of the present invention processes the source object graphics of 640*480 size in only 5 ms, less than the time (260 ms) processed by the digital signal processor alone and the time (6 ms) processed by the two-dimensional graphics acceleration device alone.

Due to the different performance of different digital signal processors, the final results of different digital signal processors may vary slightly. Tests have shown that 80M mips (including 80M) digital signal processor with two-dimensional graphics acceleration device can smoothly complete a variety of two-dimensional effects.

Preferably, the two-dimensional graphics acceleration device can perform the corresponding special effect display effect in the display memory space through the two-dimensional special effect transplantation interface function, and the specific syntax format, function, parameter meaning and return value meaning of each two-dimensional special effect transplantation interface function. See Tables 2 to 6 below.

The 2D effect porting interface is designed based on the most basic hardware functions of the 2D graphics acceleration device that comes with the digital signal processor. It also provides for more complex hardware functions such as command queues. Parameter input. Therefore, whether it is a complex two-dimensional graphics acceleration device or a simple two-dimensional graphics acceleration device, the migration interface function does not have to be modified. Taking the filling rectangle and the block moving interface function as an example, see Table 7 for the parameter transfer meaning table of the transplant interface function on different acceleration devices.

The platforms that have been successfully transplanted include STMicroelectronics' STi51XX series DSP, BroadCom's 974XX series DSP, LSI's SC20XX series DSP, Huawei HISI's 3XXX series DSP, and Intel's CE21XX series DSP.

Step 207: The two-dimensional graphics acceleration device outputs the target object graphic to the display screen.

In the embodiment of the present invention, the digital signal processor and the two-dimensional graphics acceleration device respectively perform the two-dimensional special effect processing of the source object graphic, and the processing of the two-dimensional graphic special effect display of the source object graphic is distributed to the two devices, and the two-dimensional graphics are accelerated. The processing speed of the device is much higher than that of the digital signal processor, so that most of the processing of the two-dimensional graphics effect display is completed by the two-dimensional graphics acceleration device in the display memory space, reducing the occupancy and performance of the digital signal processor.
