Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The main solution of the embodiment of the present invention is: receive a two-dimensional code display instruction, and obtain the characteristic character code according to the two-dimensional code display instruction; obtain the characteristic character code according to the preset two-dimensional code display area and display gray scale The display parameters of the code; the data information of the original two-dimensional code is obtained, and the target two-dimensional code is generated according to the data information of the original two-dimensional code, the characteristic character code and the display parameters; the generated target two-dimensional code is displayed .

Due to the low recognition of the two-dimensional codes generated by smart TVs in the prior art, users cannot distinguish between different two-dimensional codes before scanning, and know the meaning of the two-dimensional codes. The QR code displayed on the TV screen until the desired web page or application is obtained. It wastes the user's time and seriously affects the user experience.

The present invention provides a solution, so that the smart TV generates a personalized two-dimensional code with a specific logo based on the original initial two-dimensional code, and displays it according to a certain arrangement rule, so that the user can scan the two-dimensional code in advance Know the meaning of the QR code.

Referring to FIG. 1 , the first embodiment of the method for generating and displaying a two-dimensional code of the present invention provides a method for generating and displaying a two-dimensional code. The method for generating and displaying a two-dimensional code includes:

Step S10, receiving a two-dimensional code display instruction, and acquiring a characteristic character code according to the two-dimensional code display instruction.

The present invention is mainly applied to smart TVs to create two-dimensional codes, and users can use the two-dimensional codes displayed on smart TVs to download and install application programs, quickly link to application websites, obtain program information, and perform operations such as TV shopping. Of course, the present invention can also be applied to the creation of two-dimensional codes of other intelligent terminals.

In the embodiment of the present invention, the two-dimensional code display instruction may be triggered by the user using the remote control, or by the user's voice, or by the TV system at regular intervals, or by the TV system preset according to the broadcast program, or by It is another trigger method, which can be flexibly set according to actual needs.

Specifically, as an implementation manner, firstly, the television system detects the two-dimensional code display instruction, and when the user or the television system triggers the two-dimensional code display instruction, the television system acquires the two-dimensional code display instruction.

Wherein, there may be one two-dimensional code display instruction, or there may be multiple at the same time. The two-dimensional code display instruction includes the target two-dimensional code to be generated by this two-dimensional code display instruction, for example: the link two-dimensional code of the video website Iqiyi, the link two-dimensional code of the video website Youtubu.

Then, according to the two-dimensional code display instruction, the TV system reads the name of the target two-dimensional code application, and extracts the package name of the application. Search for the first character code of the application package name against the preset character code, and use this character code as the characteristic character code corresponding to this QR code display command, that is, the characteristic character code of the target QR code this time.

If there are currently multiple two-dimensional code display instructions, the corresponding characteristic character codes are sequentially obtained according to the time sequence in which the two-dimensional code display instructions are obtained. If the characteristic character code obtained by this two-dimensional code display instruction has been used, obtain the second character code obtained by comparing the application package name with the character code, and use it as the characteristic character code corresponding to this two-dimensional code display instruction. By analogy, the multiple current two-dimensional code display instructions all correspond to unique and different characteristic character codes.

Different two-dimensional code display instructions have unique corresponding characteristic character codes, so that the two-dimensional codes created by different two-dimensional code display instructions have unique and different identifications. Wherein, the feature character code can be a character or a number, which can be flexibly set according to actual needs.

It should be noted that the preset character code can be ASCII (American Standard Code for Information Interchange, American Standard Code for Information Interchange) code or other standard codes, which can be flexibly set according to actual needs.

Then, the television system stores the acquired characteristic character code in the first buffer area. The characteristic character code is stored separately, so that the TV system can access the characteristic character code conveniently and quickly, without interfering with the cache file access during the subsequent two-dimensional code generation process of the TV system.

The target two-dimensional code of the current two-dimensional code display instruction is the link two-dimensional code of the video website Youtube and the link two-dimensional code of the video website Iqiyi in turn as examples for illustration.

The TV system receives the current two QR code display instructions. First, according to the link QR code display instruction of the video website Youtubu, read the package name of the video website Youtubu application to obtain Youtubu, and then check the ASCII code to find the corresponding application package name Youtubu. The first character code, get Y.

Then, according to the link QR code display instruction of the video website Iqiyi, read the package name of the video website Iqiyi application to obtain Iqiyi, and then search for the first character code corresponding to the application package name Iqiyi according to the ASCII code, and obtain I.

When obtaining the link QR code display instruction of the video website Youtube and the characteristic character code corresponding to the link QR code display instruction of the video website Iqiyi, the following algorithm can be used:

AP_PK_Name(x1)=YouTubu, the package name of the application read by the TV system;

Dif_AP_TAG(x1)=Y, the TV system finds the first character code by comparing with the ASCII code.

AP_PK_Name(x2)=Iqiyi, the package name of the application read by the TV system;

Dif_AP_TAG(x2)=1, the television system finds the first character code with ASCII code comparison.

Thus, the TV system obtains the characteristic character code Y corresponding to the link QR code display instruction of the video website Youtubu, and the characteristic character code I corresponding to the link QR code display instruction of the video website Iqiyi.

Step S20, acquiring the display parameters of the characteristic character code according to the preset two-dimensional code display area and display gray scale.

After obtaining the characteristic character code of the two-dimensional code display instruction, the TV system obtains the display parameters of the characteristic character code when displaying the characteristic character code according to the preset two-dimensional code display area and display gray scale.

Specifically, as an implementation manner, firstly, the television system detects the characteristic character code in the first storage area.

After the characteristic character code is detected, the TV system reads the detected characteristic character code and stores it in the second buffer area, which is used for obtaining the display parameters of the characteristic character code and generating the subsequent target two-dimensional code. Through the division of the first buffer area and the second buffer area, the television system prevents data storage and use from interfering with each other, and improves data processing efficiency.

Then, the TV system reads the preset display area of the target two-dimensional code to obtain the display area size of the target two-dimensional code, and obtains the display size of the characteristic character code according to the preset ratio of the display area size of the target two-dimensional code.

Then, according to the grayscale displayed on the preset smart TV screen, the TV system takes the random grayscale value of the grayscale displayed on the smart TV screen, and uses the grayscale corresponding to the obtained random grayscale value to gain the initial color of the characteristic character code to obtain Gain color of feature character code.

The gain color displayed by the characteristic character code is used to highlight the characteristic character code and distinguish different QR codes displayed at the same time. It should be noted that the gray scale of the smart TV screen can be 256 levels or other levels, which can be flexibly set according to actual needs.

Thus, the television system obtains the display parameters of the characteristic character code. Wherein, the display parameters of the characteristic character code include the display size and gain color of the characteristic character code.

Step S30, acquiring the data information of the original two-dimensional code, and generating a target two-dimensional code according to the data information of the original two-dimensional code, the characteristic character code and the display parameters.

After obtaining the display parameters of the characteristic character code, the TV system obtains the original two-dimensional code data information of this two-dimensional code display instruction, and according to the data information of the original two-dimensional code, the characteristic character code corresponding to this two-dimensional code display instruction and the display parameters of the characteristic character code to generate the target two-dimensional code.

Specifically, as an implementation manner, firstly, the television system reads the corresponding original two-dimensional code according to the current two-dimensional code display instruction. Analyze the original two-dimensional code to obtain the data information of the original two-dimensional code.

Then, according to the data information of the original two-dimensional code, the characteristic character code and the display parameters of the characteristic character code, a target two-dimensional code is created. The display size of the target two-dimensional code can be obtained according to a preset ratio according to the display size of the characteristic character code.

The characteristic character code is located in the filling area of the target two-dimensional code, and is displayed with corresponding display parameters. The data code of the target two-dimensional code is displayed in the initial color black, and the characteristic character code is highlighted.

Then, the created target two-dimensional code is masked to generate the target two-dimensional code, so that the black and white display of the generated target two-dimensional code is balanced, and the reliability of data reading is enhanced. Referring to FIG. 2 , in this embodiment, the target two-dimensional code can have multiple preset masking schemes, which can be randomly selected during masking processing, and the masking process is performed according to the corresponding masking formula.

Thus, the television system obtains the generated target two-dimensional code.

Step S40, displaying the generated target two-dimensional code.

After obtaining the generated two-dimensional codes, the television system arranges and displays the generated two-dimensional codes according to preset rules.

Specifically, as an implementation manner, firstly, the television system reads the currently generated two-dimensional code. There can be one or more QR codes currently generated.

Then, the television system displays the generated two-dimensional code in the preset two-dimensional code display area according to the preset arrangement rule.

The preset two-dimensional code arrangement rule can be based on the popularity of the two-dimensional code icon as the order of arrangement, for example: the higher the number of times the two-dimensional code icon is clicked and generated within the preset time, the priority will be arranged and displayed on the left side of the smart TV screen; The higher the number of clicks on QR code-related applications within the preset time, they will be prioritized and displayed on the left side of the smart TV screen; the longer the user stays in QR code-related applications within the preset time, they will be prioritized and displayed on the smart TV The left side of the screen; within the preset time, the QR code that the user scans more times will be prioritized and displayed on the left side of the smart TV screen. Of course, the preset two-dimensional code arrangement rules can be other arrangement orders, which can be flexibly set according to actual needs.

Thus, the television system displays the generated two-dimensional code for the user to scan and use. Since the generated two-dimensional codes are marked with corresponding characteristic character codes when displayed, users can know the meaning of the two-dimensional codes before scanning the two-dimensional codes, scan the two-dimensional codes currently needed, and obtain data information.

In this embodiment, the TV system obtains the corresponding characteristic character code according to the two-dimensional code display instruction by receiving the two-dimensional code display instruction; obtains the display of the characteristic character code according to the preset two-dimensional code display area and display gray scale parameter; then, obtain the data information of the original two-dimensional code, generate the target two-dimensional code according to the data information, characteristic character code and display parameters of the original two-dimensional code, and identify the different two-dimensional codes generated by the characteristic character code; then press preset The generated target QR code is displayed according to the rules, so that users can quickly distinguish different QR codes. This embodiment enhances the recognition of the two-dimensional code, enabling the user to know the meaning of the two-dimensional code in advance when scanning the two-dimensional code, and distinguish different two-dimensional codes, thereby improving the user experience.

Further, referring to FIG. 3 , the second embodiment of the method for generating and displaying a two-dimensional code of the present invention provides a method for generating and displaying a two-dimensional code. Based on the embodiment shown in FIG. 1 above, the display parameters of the characteristic character code include the The display size and gain color of characteristic character code, described step S20 comprises:

Step S21 , according to the preset two-dimensional code display area, acquire the display size of the characteristic character code.

After obtaining the characteristic character code corresponding to the two-dimensional code display instruction, the television system obtains the display size of the characteristic character code when generating the target two-dimensional code.

Specifically, as an implementation manner, firstly, the television system reads the preset display area of the target two-dimensional code to obtain the size of the preset target two-dimensional code display area.

Then, the TV system obtains the magnification factor of the characteristic character code according to the size of the display area of the target two-dimensional code and according to the preset ratio.

Then, the TV system enlarges the initial size of the characteristic character code according to the obtained magnification factor to obtain the display size of the characteristic character code.

Step S22 , according to the preset display grayscale, acquire the gain color of the characteristic character code.

After obtaining the characteristic character code corresponding to the two-dimensional code display instruction, the television system obtains the gain color of the characteristic character code when displaying the target two-dimensional code.

Specifically, as an implementation manner, the TV system is preset with display gray scales of the screen of the smart TV, and the gray scale values are in one-to-one correspondence with different levels of color brightness that the smart TV can display.

First, take the total number of current two-dimensional code display instructions as n, and the TV system randomly selects n different gray scale values according to the total number n of current two-dimensional code display instructions. If any two of the randomly obtained gray scale values are the same, reselect until n different gray scale values are obtained.

Thus, the grayscale value corresponding to each two-dimensional code display instruction is obtained.

The initial color of the characteristic character code corresponding to the two-dimensional code command is the preset color, and the gray level corresponding to the gray scale value is filled to obtain the gain color when each characteristic character code is displayed.

The gain color displayed by the characteristic character code is used to highlight the characteristic character code and distinguish different QR codes displayed at the same time.

In this embodiment, the display parameters of the characteristic character code include the display size and gain color of the characteristic character code; the television system obtains the display size of the characteristic character code according to the preset two-dimensional code display area; Gray scale, obtain the gain color of the characteristic character code, and obtain the display parameters of the characteristic character code. This embodiment obtains the display size and gain color of the characteristic character code when generating the two-dimensional code, so that the characteristic character code can be highlighted, the recognition of the two-dimensional code is enhanced, and the user can know in advance when scanning the two-dimensional code The meaning of the QR code, distinguishing different QR codes, and improving the user experience.

Further, referring to FIG. 4 , the third embodiment of the method for generating and displaying a two-dimensional code of the present invention provides a method for generating and displaying a two-dimensional code. Based on the above-mentioned embodiment shown in FIG. 3 , the step S21 includes:

Step S211 , according to the preset two-dimensional code display area, obtain the horizontal size of the two-dimensional code display area.

When the TV system obtains the display size of the characteristic character code when generating the target two-dimensional code, specifically, as an implementation, first, the TV system obtains the horizontal direction of the target two-dimensional code display area according to the preset target two-dimensional code display area. The display size above to get the horizontal size of the target QR code display area.

The horizontal size of the target two-dimensional code display area is the horizontal size of the display area assigned to the target two-dimensional code after the TV system pre-plans according to the number of target two-dimensional codes to be displayed on the screen and the size of the display area.

It should be noted that the planning of the target QR code display area on the screen by the TV system can be preset, or it can be based on the number of target QR codes to be displayed on the smart TV screen and the size of the display area after receiving the QR code display instruction. The dimensions are planned and can be flexibly set according to actual needs.

Wherein, the dimension of the display area of the target two-dimensional code can be expressed in units of pixels.

Step S212. According to the horizontal size of the two-dimensional code display area, the magnification factor of the characteristic character code is obtained.

After obtaining the horizontal size of the target two-dimensional code display area, the TV system obtains the magnification factor of the corresponding characteristic character code according to the size of the target two-dimensional code display area and according to a preset ratio.

Specifically, as an implementation manner, the television system may obtain a preset ratio value of the horizontal size of the target two-dimensional code display area as the characteristic character code and the size magnification factor of the two-dimensional code created by this two-dimensional code display instruction.

Wherein, the preset ratio value can be one-tenth, or other values, which can be flexibly set according to actual needs.

Thus, the TV system obtains the magnification factor of the characteristic character code.

Step S213, enlarging the initial size of the characteristic character code according to the magnification factor of the characteristic character code to obtain the display size of the characteristic character code.

After obtaining the magnification factor of the characteristic character code, the TV system can enlarge the initial size displayed by the characteristic character code according to the magnification factor.

The original size of the characteristic character code is the system preset value, for example: 3×3 pixel matrix.

The television system enlarges the horizontal size and the vertical size of the characteristic character code according to the magnification factor, and obtains the enlarged size of the characteristic character code.

In order to keep the characteristic character code in the filling area of the target two-dimensional code when generating the target two-dimensional code, the TV system can use the magnification factor of the characteristic character code to enlarge the initial size of the target two-dimensional code, so that the target two-dimensional code and the characteristic character code The dimensions are kept in sync.

The target two-dimensional code of the current two-dimensional code display command is the link two-dimensional code of the video website Youtube and the link two-dimensional code of the video website Iqiyi in turn, and the type of the current target two-dimensional code is QR (Quick Response, quick response) two-dimensional code for example.

First, the TV system obtains the horizontal dimension of the display area of the link QR code of the video website Youtube, which is 40 pixels; then, the TV system obtains one-tenth of the 40 pixels, and obtains a magnification factor of 4 for the characteristic character code; then, The TV system enlarges the horizontal direction and the vertical direction of the initial display size of the characteristic character code four times simultaneously, and obtains the characteristic character code display size of the link QR code of the video website Youtube.

The TV system obtains the display area horizontal size of the link QR code of the video website Iqiyi, which is 20 pixels; then, the TV system obtains one-tenth of 20 pixels, and the magnification factor of the characteristic character code is 2; then, the TV system The horizontal direction and the vertical direction of the initial display size of the characteristic character code are enlarged four times at the same time, and the characteristic character code display size of the link QR code of the video website Iqiyi is obtained.

When obtaining the magnification of the characteristic character code, the following algorithm can be used:

QR_X_Size(x1)=40, the TV system obtains the link QR code display area size of the video website Youtube in the horizontal direction: 40;

Adap_QR(x1)=QR_X_Size(x1)/10=4, the TV system obtains magnification: 4.

QR_X_Size(x2)=20, the TV system acquires the link QR code display area size of the video website Iqiyi in the horizontal direction: 20;

Adap_QR(x2)=QR_X_Size(x2)/10=2, the television system obtains magnification: 2.

In this embodiment, the TV system obtains the horizontal size of the two-dimensional code display area through the preset two-dimensional code display area; then, according to the horizontal size of the two-dimensional code display area, obtains the magnification factor of the characteristic character code; then, The initial size of the characteristic character code is enlarged according to the magnification factor of the characteristic character code to obtain the display size of the characteristic character code. In this embodiment, the display size of the characteristic character code is obtained, and the characteristic character code can be displayed at an appropriate ratio when generating a two-dimensional code, so that the generated two-dimensional code remains beautiful, and it is convenient for users to identify different two-dimensional codes.

Further, referring to FIG. 5 , the fourth embodiment of the method for generating and displaying a two-dimensional code of the present invention provides a method for generating and displaying a two-dimensional code, based on the above-mentioned embodiment shown in FIG. 3 or 4 (this embodiment takes FIG. 4 as an example) , the step S22 includes:

Specifically, as an implementation, the TV system is preset with display gray scales displayed on the smart TV screen, and the gray scale displayed on the smart TV screen is represented by a gray scale value, and the gray scale value is different from the colors of different levels that the smart TV screen can display. One-to-one correspondence of brightness.

First, the TV system acquires the total number of current two-dimensional code display instructions, and takes the current total number of two-dimensional code display instructions as n.

Then, the acquired gray scale values are divided into n equal parts according to the original arrangement order to obtain n equal divided gray scale values.

Step S222. Obtain the random gray scale value of each divided gray scale value.

After equalizing the gray scale values, the television system randomly selects gray scale values in each equal gray scale value to obtain random gray scale values.

If any two obtained random gray scale values are in the same equally divided gray scale value, the television system reselects the random gray scale value until the obtained random gray scale values are in different equally divided gray scale values.

Thus, the television system obtains n random grayscale values corresponding to different two-dimensional code display instructions.

Step S223. Obtain the gain color of the characteristic character code according to the obtained random gray scale value.

After obtaining the random grayscale value corresponding to each two-dimensional code display instruction, the random grayscale value is the color gain value of the characteristic character code.

The TV system fills the initial color of the characteristic character code corresponding to the two-dimensional code display instruction with the gray scale corresponding to the random gray scale value, and obtains the gain color of the characteristic character code when displaying the characteristic character code.

Create_QR_Rev(x2)=I, the TV system generates the corresponding two-dimensional code icon according to the display parameters from the original two-dimensional code and characteristic character code I of the video website Iqiyi link two-dimensional code.

Step S340: Correct the created two-dimensional code according to the second error correction code to generate a target two-dimensional code.

After obtaining the created target two-dimensional code, the television system uses the second error correction code to correct the created target two-dimensional code.

Specifically, as an implementation manner, the television system reads the second error correction code and the current data code of the target two-dimensional code created this time.

Then, according to the preset character code, the TV system inverts the character code of the second error correction code and subtracts the character code of the current data code. If the obtained value is 0, the current data transmission is normal; if the obtained value If it is not 0, use the second error correction code to correct the target QR code created this time.

Then, according to the preset character code, the correcting unit 340 inverts the character code of the second error correction code, and then subtracts the character code of the current data code. If the obtained value is 0, the current data transmission is normal; If the value is not 0, use the second error correction code to correct the target QR code created this time.

Then, a preset mask scheme is selected for the created target two-dimensional code to perform mask processing to generate the target two-dimensional code.

The generated target two-dimensional code contains a characteristic character code, and the characteristic character code is located in the filling area of the target two-dimensional code, which does not affect the reading of data when the user scans the target two-dimensional code.

Referring to Figure 7, the target two-dimensional code of the current two-dimensional code display command is the link two-dimensional code of the video website Youtube and the link two-dimensional code of the video website Iqiyi in sequence, and the type of the current target two-dimensional code is a QR two-dimensional code for example illustrate.

A characteristic character code Y is displayed in the filled area of the two-dimensional code of the link of the obtained video website Youtube; a characteristic character code I is displayed in the filled area of the two-dimensional code of the link of the obtained video website Iqiyi.
