Wherein, the terminal device may be, but is not limited to, a mobile terminal (tablet computer or smart phone), a fixed terminal device (such as a desktop computer).

The application end may be a plug-in of a client embedded in the terminal device, or a plug-in of the operating system of the terminal device, and the information transmission client embedded in the terminal device or the operating system of the terminal device. The application end can also be an independent client in the terminal device that can provide information transmission, which is not limited in this embodiment.

FIG. 1 is a schematic flowchart of an information transmission method provided in Embodiment 1 of the present invention, as shown in FIG. 1 , which specifically includes:

S101. Encode the information to be transmitted into image data suitable for video data line transmission.

The information includes, but is not limited to, control instructions in voice form, control instructions in text form, and control instructions entered by keyboard. The control instruction may be, but not limited to, a power-on instruction, a power-off instruction, a play instruction, a fast-forward instruction, a pause instruction, and the like.

Wherein, the video data line is used to transmit video signals, including but not limited to any of the following: audio and video data line (Audio Video Cable, AV line), S terminal line, three color difference line, video graphics array data line ( VideoGraphics Array, VGA), digital video interface data line (Digital Visual Interface, DVI), high definition multimedia interface line (High Definition Multimedia Interface, HDMI).

Specifically, the information to be transmitted can be encoded into an image format, so that the information to be transmitted exists in the form of image pixel values, so that the corresponding image data can be transmitted through the video data line, on the one hand, the use of complex video bottom layers can be avoided. The protocol processes information, on the other hand, it can achieve the purpose of transmitting information without a network.

S102. Use the video data line to transmit the image data.

Specifically, the video data line can be used to send the image data to the receiving device. After the receiving device receives the image data, it decodes the image data to obtain corresponding information, and the receiving device can perform corresponding operations according to the information. For example, when the information is a video playing instruction, the receiving device starts to play the video and so on.

In this embodiment, the information to be transmitted is encoded into image data, and then transmitted through the video data line. On the one hand, it can avoid the R&D personnel to use the complex video bottom layer protocol to encode the information, which saves labor costs. On the other hand, even if In the case of no network, information can also be successfully transmitted, thereby improving the efficiency of information transmission.

Exemplarily, the encoding of the information to be transmitted into image data suitable for video data line transmission includes:

Perform quantization processing on the content contained in the information, and use the corresponding quantized value as the pixel value of the first image;

According to the pixel value of the first image and the preset basic image, image data suitable for video data line transmission is obtained.

The content included in the information may be, but not limited to, text information and voice information. The base image can be, but is not limited to, a blank image, an existing image, or another customized image.

Specifically, if the information is text information, each character included in the text information may be binarized, for example, 0 or 1 is used to represent each character, or 0 or 255 is used to represent each character. Alternatively, the numerical value corresponding to each character is normalized between 0 and 255, so that the quantized value corresponding to each character is any numerical value from 0 to 255, and so on.

Embodiment 2

In this embodiment, the obtaining image data suitable for video data line transmission according to the first image pixel value and the preset basic image includes: if the basic image If the image is a pre-created blank image, the pixel value of the first image is added to the corresponding position of the blank image to obtain the image data.

Correspondingly, the method of this embodiment specifically includes:

S201. Perform quantization processing on the content contained in the information to be transmitted, and use the corresponding quantized value as the pixel value of the first image.

Specifically, taking the information content as text information as an example, a quantitative example that can be used in this embodiment is as follows: first, convert the text information into a long string, calculate the total number of bytes of the string, and convert the entire string into a corresponding One byte corresponds to 8 binary bits, and the total number of binary digits is 8 times the total number of bytes, so a binary sequence is formed, and each binary number (ie, 0 or 1) in the binary sequence is used as the first image. Pixel values.

S202. If the base image is a pre-created blank image, add the pixel value of the first image to a corresponding position of the blank image to obtain the image data.

The blank image is an image whose pixel values are all 0 or 1.

Specifically, you can use the opencv open source library to create a blank image. All the pixel values of the blank image are 0 or 1. Write the binary sequence in S201 into the blank image in sequence. 8 1s mark the end of the binary sequence.

In addition, when there is no information loss in the image during transmission, decoding can completely restore the original information, but considering that there may be information loss during the transmission process, such as a slight change in the image pixel value, an error occurs when parsing the image. A fault-tolerant mechanism is considered, that is, 0 and 1 are not directly stored during encoding, but if the value is 0, 0 is stored, and if the value is 1, 255 is stored. After transmission, even if the pixel value changes slightly, If some 0 become 3 or 5, some 255 become 245 or 251, etc., binarize the image received by the receiver, for example, take the binarization threshold as 128, if the value is less than 128, set it to 0 , if the value is greater than 128, it is set to 1, so that the loss in the transmission process can be accommodated, and the original information can be completely restored.

S203. Use a video data line to transmit the image data.

Specifically, the image data is transmitted through the video data line. After the receiving device receives the image data, it traverses the pixel values of the image data from the beginning. Every 8 values obtained are parsed into one byte and stored in the byte array. The end flag is 8 consecutive 1s, indicating that all the encoded methods have been obtained, stop traversing, and convert the byte array into a string, that is, the entire encoding->transmission->decoding process is completed.

In this embodiment, the information to be transmitted is quantized, and the pixel value of the first image is added to the corresponding position of the blank image by creating a blank image to obtain image data suitable for video data line transmission. It can be seen that, on the one hand, developers can avoid using complex video underlying protocols to encode information, saving labor costs, on the other hand, information can be successfully transmitted even without a network, thereby improving information transmission efficiency.

S402. If the base image is an existing image, extract a pixel value at a preset position in the base image as a second image pixel value.

Specifically, the existing image is directly used as the base image. When it is an existing image, the corresponding second image pixel value is the image pixel value at the preset position in the existing image. The image pixel values at the preset number of positions may be selected as the second image pixel value according to the byte size included in the information.

S403. Recalculate the pixel value at the preset position according to the pixel value of the first image and the pixel value of the second image, and use the recalculated data corresponding to the base image as the image data.

Specifically, the pixel value of the first image and the pixel value of the second image at the corresponding position can be calculated by adding, subtracting, or weighting, and taking the calculated pixel value as the pixel value at the preset position, and recalculating The obtained data corresponding to the existing image is transmitted as image data.
