Abstract

The invention is applicable to the technical field of screen transmission, and a method and apparatus for wireless screen transmission are provided. The method includes steps: receiving a video streamsent by the sending end, decoding the video stream to obtain at least one screen frame of the first screen, at least one screen frame being buffered to a buffer area as a frame to be play, comparingthe number of frames to be played in the buffer area with the size of the first threshold value, if the number of frames to be played in the buffer area is less than or equal to the first threshold value, playing a frame to be played in the buffer area according to the first rule, otherwise, the frame to be played in the buffer area is played according to the second rule, within the same time, thenumber of frames to be played in the playback buffer area according to the second rule is larger than the number of frames to be played in the playback buffer area according to the first rule. The invention accelerates the clearance speed of the frame to be played in the buffer area of the receiving end, avoids the accumulation of a large number of frames to be played in the buffer area of the receiving end, thereby shortening the playback time difference between the receiving end and the sending end, and solves the problems that the receiving end and the sending end are not synchronous and the playback delay is long in the prior art wireless screen transmission technology.

Description

technical field [0001] The invention belongs to the technical field of screen transmission, and in particular relates to a wireless screen transmission method and device. Background technique [0002] Using wireless screen transmission technology, the content on one device is transmitted to another device for display and playback through the wireless network, for example: the video and audio played on the computer screen are transmitted to the TV for playback, and the screen of the mobile phone is transmitted and displayed to the TV Wait on the screen. At present, it is widely used in conferences and places where there is a need for content sharing in the education field. With the development of wireless networks, the application of wireless screen transmission technology is becoming more and more extensive. [0003] Since the wireless screen transfer adopts wireless network transmission, affected by the actual network and data processing time loss, the wireless screen tran...
