s101, encoding information to be transmitted into image data suitable for video data line transmission.
The information includes, but is not limited to, a control command in a voice form, a control command in a text form, and a control command input by a keyboard. The control command may be, but is not limited to, a power-on command, a power-off command, a play command, a fast-forward command, a pause command, and the like.
The video data line is used for transmitting video signals, and includes but is not limited to any one of the following: audio and Video data lines (AV lines), S terminal lines, tristimulus lines, Video Graphics Array (VGA), Digital Video Interface (DVI) data lines, and 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, and corresponding image data can be transmitted through a video data line, so that on one hand, the information can be prevented from being processed by using a complex video underlying protocol, and on the other hand, the purpose of transmitting the information under the condition of no network can be achieved.
And S102, transmitting the image data by adopting the video data line.
Specifically, the video data line may be used to transmit image data to the receiving device, and after the receiving device receives the image data, the receiving device decodes the image data to obtain corresponding information, and the receiving device may perform corresponding operations according to the information. For example, when the information is a video playing instruction, the receiving device starts playing a video, and so on.
The embodiment encodes the information to be transmitted into image data, and then transmits the image data through the video data line, so that on one hand, research personnel can be prevented from using a complex video bottom layer protocol to encode the information, the labor cost is saved, on the other hand, the information can be successfully transmitted even under the condition of no network, and the information transmission efficiency is further improved.
Illustratively, encoding the information to be transmitted as image data suitable for transmission over the video data line comprises:
performing quantization processing on the content contained in the information, and taking a corresponding quantization value as a first image pixel value;
and obtaining image data suitable for video data line transmission according to the first image pixel value and a preset basic image.
The content contained in the information may be, but is not limited to, text information and voice information. The base image may be, but is not limited to, a blank image, an existing image, or other customized image.
Specifically, if the information is text information, each character included in the text information may be binarized, for example, each character is represented by 0 or 1, or each character is represented by 0 or 255. Or, normalizing the numerical value corresponding to each character between 0 and 255 to make the quantization value corresponding to each character be any numerical value between 0 and 255, and the like.

In this embodiment, the obtaining image data suitable for transmission of a video data line according to the first image pixel value and a preset basic image includes: and if the basic image is a blank image created in advance, adding the first image pixel value to the corresponding position of the blank image to obtain the image data.
Correspondingly, the method of the embodiment specifically includes:
s201, quantizing the content contained in the information to be transmitted, and taking the corresponding quantized value as a first image pixel value.
Specifically, taking the information content as text information as an example, one quantization example that can be adopted in the present embodiment is as follows: firstly, converting text information into a long character string, calculating the total byte number of the character string, converting the whole character string into corresponding binary digits, wherein one byte corresponds to 8 binary digits, and the total byte number is 8 times of the total byte number, so that a binary sequence is formed, and each binary digit (namely 0 or 1) in the binary sequence is used as a first image pixel value.
S202, if the basic image is a blank image created in advance, adding the first image pixel value to the corresponding position of the blank image to obtain the image data.

In addition, when the image has no information loss during transmission, the decoding can completely restore the original information, but considering that there may be information loss during transmission, such as slight change of the image pixel value, which causes errors during parsing of the picture, this embodiment considers a fault-tolerant mechanism, i.e. when encoding, 0 is not directly stored, 0 is stored if the value is 0, 255 is stored if the value is 1, after transmission, even if the pixel value has slight change, such as some 0 is changed into 3 or 5, some 255 is changed into 245 or 251, etc., the image received at the receiving end is binarized, such as taking the binarization threshold value as 128, if the value is less than 128, 0 is set, if the value is greater than 128, 1 is set, so that there is a tolerance for the loss during transmission, and the original information can be completely restored.
And S203, transmitting the image data by adopting a video data line.
Specifically, image data is transmitted through a video data line, after receiving the image data, the receiving device traverses the pixel values from the beginning for the image data, analyzes each acquired 8 values into one byte, stores the byte into a byte array, and when 8 continuous 1 ending marks are met, the situation that all the encoded modes are acquired is shown, the traversal is stopped, the byte array is converted into a character string, and then the whole encoding- > transmission- > decoding process is completed.
In the embodiment, the information to be transmitted is quantized, and the first image pixel value is added to the corresponding position of the blank image in a manner of creating the blank image, so that the image data suitable for the transmission of the video data line is obtained. Therefore, on one hand, research personnel can be prevented from using a complex video bottom layer protocol to code information, labor cost is saved, on the other hand, information can be successfully transmitted even under the condition of no network, and information transmission efficiency is improved.

Correspondingly, the method of the embodiment specifically includes:
s301, quantizing the content contained in the information to be transmitted, and taking the corresponding quantized value as a first image pixel value.
S302, if the basic image is an existing image, adding blank pixel points in the basic image.

Correspondingly, the method of the embodiment specifically includes:
s401, carrying out quantization processing on the content contained in the information to be transmitted, and taking the corresponding quantization value as a first image pixel value.
S402, if the basic image is an existing image, extracting a pixel value at a preset position in the basic image to serve as a second image pixel value.
Specifically, the existing image is directly used as the base image. When the image 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 can be selected as the second image pixel values according to the byte size contained in the information.
And S403, recalculating to obtain the pixel value at the preset position according to the first image pixel value and the second image pixel value, and taking the data corresponding to the recalculated basic image as the image data.
Specifically, the first image pixel value and the second image pixel value at the corresponding positions may be subjected to calculation such as addition, subtraction, or weighting, the calculated pixel values are used as the pixel values at the preset positions, and the newly calculated data corresponding to the existing image may be transmitted as image data.
And S404, transmitting the image data by adopting a video data line.
