Problems solved by technology

At present, there are two types of screen projection solutions for these two types of newly connected electronic devices: the first one, the newly connected electronic devices are directly decoded and displayed, but there is a blurry screen due to the lack of available reference frames; the second one, the newly connected electronic devices The electronic device waits for an available reference frame before decoding the display, but this causes the user to wait a long time before seeing the video

Abstract

The embodiment of the invention provides an information processing method and device, first electronic equipment and a server. When the second electronic equipment is accessed in the screen projectionprocess of the first electronic equipment, a group of frame sequences output by the first electronic equipment most recently can be obtained; the second electronic equipment can quickly display the screen projection video of the first electronic equipment by decoding and displaying the frame sequence, and the frame sequence contains the initial frame which can be used as the reference frame and does not need to wait, so that the process of blurred screen or waiting for display does not occur, and the screen projection efficiency of the video conference is improved.

Description

technical field [0001] The present invention relates to the technical field of multimedia communication, and more specifically, relates to an information processing method, a processing device, a first electronic device and a server. Background technique [0002] The screen projection function has become a common means of communication for video conferencing in various industries. It has the characteristics of saving costs, saving time, strong real-time performance, and not subject to geographical restrictions. [0003] Taking the common electronic classroom scene as an example, it is a routine operation to project the teacher's screen to the student's screen. During the screen projection process, it is very likely that some students' electronic devices will be connected to the electronic classroom for the first time, or some students' electronic devices will be offline. Scenarios for re-accessing the electronic classroom. At present, there are two types of screen projectio...
