Abstract

The invention provides a data stream interaction method. The method is applied to a display process and comprises: defining a state array containing at least one first element, wherein one first element occupies one byte, one bit represents the selection state of one data stream, and the initial value of each first element represents that the initial selection state of the corresponding data stream is not selected; according to the actual selection state of each data stream corresponding to each first element, selecting a target second element corresponding to each target bit of which the actual selection state is selected from the marked data, and calculating the actual value of each first element; and updating the state array by utilizing the actual value of each first element, and outputting the updated state array. According to the method, the transmission data volume of the data stream can be reduced, the data storage space is greatly compressed, the data transmission efficiency is improved, and the risk of memory overflow caused by excessive data is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a data stream transmission method, transmission device, electronic equipment, and storage medium. Background technique [0002] The data flow refers to the data parameters exchanged within the electronic device or between electronic devices, which truly reflects the working voltage and state of the electronic device. [0003] The current general process of data stream transmission is as follows: list the names of all data streams in order, let the user select the data stream to be viewed, then store the selection status of all data streams in an array, and transmit them through memory sharing . [0004] However, since each element of the array occupies at least one byte, when the number of data streams is infinite, this transmission method occupies a very large memory, which may cause memory overflow and cause the program to crash.
