Data sending method and data receiving method

Abstract

The embodiment of the invention discloses a data sending method and a data receiving method. The data sending method comprises the steps that a sender acquires transmitted data; the sender generates noriginal data frames and m intra-frame error correction data frames according to the transmitted data, wherein n and m are both natural numbers greater than 1; the sender generates n+m frames of intra-frame error correction images according to the n original data frames and the m intra-frame error correction data frames; and the sender displays the n+m frames of intra-frame error correction images on a display. The data receiving method comprises the steps that a receiver acquires multiple frames of intra-frame error correction images through an image acquisitor; and the receiver restores themultiple frames of intra-frame error correction images to obtain the transmitted data acquired by the sender. According to the data sending method and the data receiving method, the reliability and the high rate of data transmission can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data sending and data receiving method. Background technique [0002] Data transmission is the communication process in which data is sent from one place to another. One-way transmission is a common data transmission method, which emphasizes one-way data transmission. For example, among the communication parties, one party is fixed as the sender, and the other is fixed as the receiver, and information can only be transmitted in one direction, that is, data can only be transmitted from the sender to the receiver. [0003] In the prior art, there are many one-way transmission methods, and the one-way transmission method using image recognition technology is one of them. Its main realization principle is: the computer on network A converts the data file to be transmitted into an image through graphic conversion processing, and then displays the image on t...

Problems solved by technology

[0004] The inventors of the present invention found that due to the characteristics of one-way transmission, the computer and the computer cannot complete the handshake process. When the computer fails to decode the picture and data packet loss occurs, the computer cannot be notified to retransmit, resulting in file transmission failure.

In order to ensure the reliability of transmission, the solution in the prior art is to reduce the image decoding error rate by reducing the information content of the image or prolonging the display time of the image, which makes the transmission rate significantly lower and cannot meet the needs of practical applications.
