Abstract

The invention relates to the technical field of data transmission, in particular to a video stream data fragment packaging method and device. The method is applied to a video stream data fragmentationpackaging device, and the device runs in a first working mode after being initialized and started. The method comprises the steps that if it is determined that a first fragmentation packet of a target I frame is received, switching the working mode to a second working mode; in the second working mode, receiving other fragmentation packets of the target I frame; and if it is determined that the last fragment packet of the target I frame is received, performing a packet assembling operation of the target I frame, switching the working mode to a third working mode after it is determined that thetarget I frame is assembled, and performing display control on the target I frame.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a method and device for grouping video stream data fragments. Background technique [0002] In the development of teaching scene software, the screen broadcast function is used as an auxiliary function of teaching tools, which can synchronize the teacher's demonstration film in real time, and solve the problem that students in traditional multi-functional classrooms cannot see clearly when they are far away from the projection screen. [0003] At present, the implementation of screen broadcasting is as follows: screen broadcasting software, copy the display screen content of the teacher computer to the student computer screen, the teacher computer and the student computer screen display the same content, and the student computer can see the real-time operation process of the teacher computer in real time. [0004] The screen broadcast students need to see the ...
