detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Since the recognition of the two-dimensional code generated by the prior art smart television is low, the user cannot discriminate different two-dimensional codes before scanning, know the meaning of the two-dimensional code, easily scan the wrong two-dimensional code, or need the user to repeat the scanning intelligence. The QR code displayed on the TV screen until you get the web page or application you need. It wastes the user's time and seriously affects the user experience.

The invention provides a solution for the smart TV to generate a personalized two-dimensional code with a specific identifier based on the original initial two-dimensional code, and display according to a certain arrangement rule, so that the user can pre-scan the two-dimensional code. Know the meaning of the QR code.

Referring to FIG. 1, a first embodiment of a two-dimensional code generation and display method of the present invention provides a two-dimensional code generation and display method, and the two-dimensional code generation display method includes:

Step S10: Receive a two-dimensional code display instruction, and acquire a feature character code according to the two-dimensional code display instruction.

The invention is mainly applied to a smart TV to create a two-dimensional code, and the user can use the two-dimensional code displayed by the smart television to download and install the application program, quickly link to the application website, obtain program information, and purchase television. Of course, the present invention is also applicable to the creation of two-dimensional codes of other smart terminals.

In the embodiment of the present invention, the two-dimensional code display instruction may be triggered by the user using the remote controller, or may be triggered by the user voice, or may be triggered by the television system, or may be triggered by the television system according to the program being played, or It is another trigger method, which can be flexibly set according to actual needs.

Specifically, as an implementation manner, first, 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.

Among them, the two-dimensional code display instruction may have one or multiple at the same time. The two-dimensional code display instruction includes the target two-dimensional code to be generated by the two-dimensional code display instruction, for example, the link QR code of the video website Iqiyi and the link two-dimensional code of the video website Youtubu.

Then, the television system reads the name of the target two-dimensional code application according to the two-dimensional code display instruction, and extracts the application package name. The first character code of the application package name is searched according to the preset character code, and the character code is used as the feature character code corresponding to the current two-dimensional code display instruction, that is, the feature character code of the target two-dimensional code.

If there are multiple two-dimensional code display instructions, the corresponding feature character codes are sequentially acquired according to the time sequence of acquiring the two-dimensional code display instructions. If the feature character code obtained by the two-dimensional code display instruction has been used, the second character code obtained by comparing the application package name with the character code is obtained as the feature character code corresponding to the current two-dimensional code display instruction. By analogy, the current plurality of two-dimensional code display instructions all correspond to unique and different feature character codes.

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

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

Then, the television system stores the acquired feature character code in the first buffer area. The feature character code is separately stored, so that the subsequent acquisition of the feature character code by the television system is convenient and fast, and does not interfere with the cache file access in the subsequent generation process of the two-dimensional code of the television system.

The target two-dimensional code of the current two-dimensional code display instruction is exemplified by the link two-dimensional code of the video website Youtubu and the link two-dimensional code of the video website Iqiyi.

The television system receives the current two two-dimensional code display instructions. First, according to the link of the video website Youtubu, the two-dimensional code display instruction, reads the package name of the video website Youtubu application to get Youtubu, and then searches the application package name Youtubu according to the ASCII code. The first character code, get Y.

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

When obtaining the link QR code display instruction of the video website Youtubu and the feature 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 name of the package read by the TV system to the application;

Dif_AP_TAG(x1)=Y, the TV system uses the ASCII code to find the first character code.

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

Dif_AP_TAG(x2)=I, the TV system uses the ASCII code to find the first character code.

Thus, the television system obtains the feature character code Y corresponding to the link QR code display instruction of the video website Youtubu, and the feature character code I corresponding to the link two-dimensional code display instruction of the video website Iqiyi.

Step S20: Acquire a display parameter of the feature character code according to a preset two-dimensional code display area and a display gray scale.

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

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

After detecting the feature character code, the television system reads the detected feature character code and stores it in the second buffer area for acquiring the feature character code display parameter and generating the subsequent target two-dimensional code. The division of the first buffer area and the second buffer area by the television system enables data storage and use without interference, thereby improving data processing efficiency.

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

Then, the television system displays the gray scale according to the preset smart TV screen, takes the gray scale value of the gray scale displayed on the smart TV screen, and uses the gray level corresponding to the obtained random gray scale value to gain the initial color of the feature character code, and obtains The gain color of the feature character code.

The gain color of the feature character code display is used to highlight the feature character code and distinguish the different two-dimensional 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, and can be flexibly set according to actual needs.

Thus, the television system obtains the display parameters of the feature character code. The display parameter of the feature character code includes a display size and a gain color of the feature character code.

Step S30: Obtain data information of the original two-dimensional code, and generate a target two-dimensional code according to the data information of the original two-dimensional code, the feature character code, and the display parameter.

After obtaining the display parameter of the feature character code, the television system acquires the original two-dimensional code data information of the current two-dimensional code display instruction, and according to the data information of the original two-dimensional code, the feature character code corresponding to the current two-dimensional code display instruction And the display parameter of the character code, and generate the target two-dimensional code.

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

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

The feature character code is located in the filled area of the target two-dimensional code, and is displayed by the corresponding display parameter. The data code of the target two-dimensional code is displayed in the initial color black, and the feature character code is highlighted.

Then, the created target two-dimensional code is masked to generate a target two-dimensional code, so that the generated target two-dimensional code is balanced in black and white, and the data reading reliability is enhanced. Referring to FIG. 2, the target two-dimensional code can have a plurality of preset mask schemes in the embodiment, and the mask processing can be randomly selected from the mask scheme, and the mask processing is performed according to the corresponding mask formula.

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

Step S40: Display the generated target two-dimensional code.

After the generated two-dimensional code is obtained, the television system displays the generated two-dimensional code according to a preset rule.

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

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

The preset two-dimensional code arrangement rule may be according to the heat of the two-dimensional code icon as an arrangement order, for example, the higher the number of click generations of the two-dimensional code icon in the preset time, the priority is arranged, and displayed on the left side of the smart TV screen; The higher the number of clicks of the QR code related application, the priority is displayed on the left side of the smart TV screen; the longer the user stays in the QR code related application, the priority is arranged and displayed on the smart TV. The left side of the screen; the preset two-dimensional code of the number of user scans, prioritized, displayed on the left side of the smart TV screen. Of course, the preset two-dimensional code arrangement rule may be other arrangement order, and can be flexibly set according to actual needs.

Thus, the television system displays the generated two-dimensional code for scanning by the user. Since the generated two-dimensional code has the corresponding feature character code for identification when displayed, the user can know the meaning of the two-dimensional code before scanning the two-dimensional code, scan the currently needed two-dimensional code, and obtain the data information.

In this embodiment, the recognition degree of the two-dimensional code is enhanced, and the user can 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, the second embodiment of the present invention provides a two-dimensional code generation and display method. Based on the embodiment shown in FIG. 1, the display parameter of the feature character code includes the feature character code. Display size and gain color, the step S20 includes:

Step S21: Acquire a display size of the feature character code according to a preset two-dimensional code display area.

After acquiring the feature character code corresponding to the two-dimensional code display instruction, the television system acquires the display size of the feature character code when the target two-dimensional code is generated.

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

Then, the television system acquires the magnification of the feature character code according to the preset ratio according to the size of the target two-dimensional code display area.

Then, the television system enlarges the initial size of the feature character code according to the obtained magnification to obtain the display size of the feature character code.

Step S22: Acquire a gain color of the feature character code according to a preset display gray scale.

After acquiring the feature character code corresponding to the two-dimensional code display instruction, the television system acquires the gain color of the feature character code when the target two-dimensional code is displayed.

Specifically, as an implementation manner, the television system is pre-configured with a grayscale display of the smart television screen, and the grayscale value is in one-to-one correspondence with different levels of color brightness that the smart television can represent.

First, the total number of current two-dimensional code display instructions is n, and the television system randomly selects n different grayscale values according to the total number n of the current two-dimensional code display instructions. If any of the randomly obtained grayscale values are the same, reselect them until n different grayscale values are obtained.

Thereby, the gray scale value corresponding to each two-dimensional code display instruction is obtained.

The initial color of the feature character code corresponding to the two-dimensional code instruction is a preset color, and the gray level corresponding to the grayscale value is filled, and the gain color of each feature character code is obtained.

The gain color of the feature character code display is used to highlight the feature character code and distinguish the different two-dimensional codes displayed at the same time.

In this embodiment, when the two-dimensional code is generated, the display size and the gain color of the feature character code are obtained, so that the feature character code can be highlighted, and the recognition degree of the two-dimensional code is enhanced, so that the user can know in advance when scanning the two-dimensional code. The meaning of the QR code identifies different QR codes and enhances the user experience.

Further, the third embodiment of the two-dimensional code generation and display method of the present invention provides a second-dimensional code generation and display method, based on the second embodiment of the above-described two-dimensional code generation and display method of the present invention, the step S21 includes:

Step S211: Acquire a horizontal size of the two-dimensional code display area according to a preset two-dimensional code display area.

When the television system obtains the display size of the feature character code when generating the target two-dimensional code, specifically, as an implementation manner, first, the television system acquires the horizontal direction of the target two-dimensional code display area according to the preset target two-dimensional code display area. The display size on the top gives the horizontal size of the target two-dimensional code display area.

The horizontal size of the target two-dimensional code display area is the horizontal size of the display area allocated to the target two-dimensional code after the television system performs pre-planning according to the number of target two-dimensional codes and the size of the display area displayed on the screen.

It should be noted that the planning of the target two-dimensional code display area in the screen by the television system may be preset, or the number of target two-dimensional codes and the display area that are required to be displayed according to the smart television screen after receiving the two-dimensional code display instruction. The size can be flexibly set according to actual needs.

Wherein, the representation of the size of the target two-dimensional code display area may be in units of pixels.

Step S212: Acquire a magnification factor of the feature character code according to a horizontal size of the two-dimensional code display area.

After obtaining the horizontal size of the target two-dimensional code display area, the television system acquires the magnification of the corresponding characteristic character code according to the preset ratio according to the size of the target two-dimensional code display area.

Specifically, as an implementation manner, the television system may obtain a preset scale value of the horizontal size of the target two-dimensional code display area as the feature character code and the size enlargement multiple of the two-dimensional code created by the current two-dimensional code display instruction.

The preset ratio value may be one tenth or other values, and may be flexibly set according to actual needs.

Thus, the television system obtains the magnification of the feature character code.

Step S213: Enlarge the initial size of the feature character code according to the magnification of the feature character code to obtain a display size of the feature character code.

After obtaining the magnification of the feature character code, the television system can enlarge the initial size of the feature character code display according to the magnification.

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

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

In order to maintain the target two-dimensional code, the feature character code is in the target two-dimensional code filling area, and the television system can use the magnification of the feature character code to enlarge the initial size of the target two-dimensional code, so that the target two-dimensional code and the feature character code The dimensions are kept in sync.

The target two-dimensional code of the current two-dimensional code display instruction is the link two-dimensional code of the video website Youtubu and the link two-dimensional code of the video website Iqiyi, and the current target two-dimensional code type is QR (Quick) Response, quick response) Two-dimensional code for illustration.

First, the television system obtains the horizontal size of the display area of the link QR code of the video website Youtubu, which is 40 pixels; then, the television system acquires one tenth of the 40 pixels, and obtains the magnification of the characteristic character code to 4; The television system simultaneously enlarges the horizontal direction and the vertical direction of the initial display size of the feature character code by four times, and obtains the characteristic character code display size of the linked two-dimensional code of the video website Youtubu.

The television system obtains the horizontal size of the display area of the link QR code of the video website Iqiyi, which is 20 pixels; then, the television system acquires one tenth of 20 pixels, and obtains a magnification of the characteristic character code of 2; then, the television system The horizontal direction and the vertical direction of the initial display size of the feature character code are simultaneously magnified four times to obtain the feature character code display size of the linked two-dimensional code of the video website Iqiyi.

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

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

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

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

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

In this embodiment, the display size of the feature character code is obtained. When the two-dimensional code is generated, the feature character code can be displayed in a suitable ratio, so that the generated two-dimensional code is beautiful, and the user can recognize different two-dimensional codes.

Further, the fourth embodiment of the present invention provides a two-dimensional code generation and display method, which is based on the second embodiment or the third embodiment of the present invention. The third embodiment of the invention for generating a two-dimensional code generation method is as an example), and the step S22 includes:

Step S221: Perform a grayscale value equalization on the preset display grayscale to obtain an equally divided grayscale value.

Specifically, as an implementation manner, the television system is pre-configured with a grayscale display of the smart TV screen display, and the grayscale display of the smart television screen is represented by grayscale values, and the grayscale value and the color of the different levels of the smart television screen can be expressed. The brightness corresponds one by one.

First, the television system obtains the total number of current two-dimensional code display instructions, and takes the total number of current two-dimensional code display instructions to be n.

Then, the obtained grayscale values are equally divided into n in the original arrangement order to obtain n-divided grayscale values.

Step S222: Acquire a random grayscale value of each of the grayscale values.

After averaging the grayscale values, the television system randomly selects grayscale values in each of the gradation grayscale values to obtain random grayscale values.

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

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

Step S223: Obtain a gain color of the feature character code according to the acquired random grayscale 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 feature character code.

The television system displays the initial color of the characteristic character code corresponding to the instruction by the two-dimensional code, and fills the gray level corresponding to the random grayscale value to obtain the gain color of the characteristic character code when the characteristic character code is displayed.

In this embodiment, the random grayscale values of each feature character code are in different equal-gradation grayscale values, so that the gain color of the feature character code can be significantly distinguished, and the recognition degree of different two-dimensional codes is enhanced, so that It is easier for users to distinguish between different QR codes.

Further, the fifth embodiment of the present invention provides a two-dimensional code generation and display method, which is based on the fourth embodiment of the present invention, and the data information of the original two-dimensional code includes The positioning pattern position, the version information, the data code, and the error correction code of the original two-dimensional code, the step S30 includes:

Step S310: Obtain data information of the original two-dimensional code, correct the data code according to the error correction code, and obtain the corrected data code.

The television system searches for the original two-dimensional code corresponding to the current two-dimensional code display instruction according to the two-dimensional code display instruction.

After obtaining the original two-dimensional code, the television system parses the original two-dimensional code to obtain the data information carried by the original two-dimensional code. The data information carried by the original two-dimensional code may include a positioning pattern position, a version information, a data code, and an error correction code of the original two-dimensional code, and may also include other information, and may be flexibly set according to actual needs.

After obtaining the original two-dimensional code data information corresponding to the current two-dimensional code generation instruction, the data information of the original two-dimensional code includes the positioning pattern position, version information, data code and error correction code of the original two-dimensional code, and the television system corrects the obtained Data code.

Specifically, as an implementation manner, the television system acquires an error correction code and a data code of the original two-dimensional code, and corrects the data code by using an error correction code to avoid errors generated during data transmission.

Thereby, the television system acquires the corrected data code.

Step S320: Acquire a second error correction code according to the corrected data code.

The television system acquires a second error correcting code for generating a target two-dimensional code according to the currently obtained corrected data code.
