Problems solved by technology

[0008] The disadvantage is also obvious, that is, the drawing or text content displayed on the student terminal is quite abrupt, and a paragraph of text or drawing data is suddenly displayed on the PPT. strokes or after writing this paragraph, then the student will not match what the teacher said with the drawing or text data on the PPT displayed on the student terminal. When the teacher speaks part of the content, the text or drawing data suddenly appears on On PPT, it is more embarrassing

Embodiment Construction

[0031] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to figure 1 , the method for improving the synchronism of brush and text video live broadcast of the present invention, comprises the following steps:

[0033] S1. The student terminal requests historical data from the background and analyzes it, and executes step S2;

[0034] If the teacher end has a student enter the live broadcast room during the lecture, it is likely that the teacher has already drawn a part of the picture or written some text on the PPT at this time. When the student end just enters the live broadcast room, it first needs to request historical drawing data. And text data, get all the drawn pictures and written text on the PPT through http requests, and store the data in the memory, then organize this part of the data, and draw this part of the data to the corresponding page of the corresponding PPT at o...

Abstract

The invention discloses a method for improving the live video broadcast synchronism of a paintbrush and characters. The method comprises the following steps that a student terminal requests historicaldata from a background and analyzes the historical data; socket long connection is established between the student terminal and a teacher terminal; the teacher terminal regularly poll and check whether the content in a current text input frame is changed or not, and if the characters are changed, character information in the current text input frame is sent to the student terminal in a full-quantity mode; in the process that the teacher terminal presses a mouse, starts to draw, lifts the mouse and completes drawing through the paintbrush, the teacher terminal regularly sends graph data information drawn by the current paintbrush to the student terminal in an increment mode; the student terminal organizes the information received from the background and the teacher terminal and saves the information in a memory; the student terminal draws pictures or writes the characters on a corresponding PPT page. According to the method, the data of the teacher terminal conducting live video broadcast is transmitted to the student terminal in real time from the beginning to the end, and the data is smoothly displayed at high synchronism and high instantaneity.

Description

technical field [0001] The invention relates to a method for improving the synchronization of video live broadcast, in particular to a method for improving the synchronization of brush and text video live broadcast, and belongs to the technical field of network video live broadcast. Background technique [0002] Nowadays, there are many live broadcast platforms, and the live broadcast technology is quite mature. In educational live broadcast software, the teacher may write text, draw pictures, draw curves, etc. on the PPT through the live broadcast software at the same time of the live broadcast. These texts or graphics are quickly and real-time communicated to the student terminal for students to see, instead of abruptly displaying the final graphics or text on the student terminal after the teacher has finished drawing a stroke or writing a paragraph of text, this invention solves the problem This is the problem. This product is used in educational live broadcast software....
