Problems solved by technology

[0003] In practical applications, in order to ensure that the client and the server can achieve real-time synchronous playback of the same information, usually the client generates a frame of data and receives a frame of data on the server. In theory, this can achieve real-time synchronization. However, In practical applications, when a user of a transmission terminal sends data to the client in a conference, and several people view the same video at the same time through screen projection, due to factors such as the difference between the speed of data encoding and decryption or the delay of network transmission, It often causes the data sent by the main control terminal (server) to be out of sync with the data received by the projection terminal (client), resulting in freezes, blurred screens, and even playback stoppages

Abstract

The invention discloses a transmission control method and system for screen projection and a readable memory medium. The transmission control method for the screen projection is applied to a transmission control system for the screen projection. The transmission control system for the screen projection comprises a server side and a client side which are in communication connection. The transmission control method for the screen projection comprises the following steps that when the server side starts a screen projection mode, the server side obtains data information of the screen projection; the server side codes the data information and caches the data information to a sending queue of the server side, so the data information in the sending queue is sent to the client side; and when the server side receives length warning information sent by the client side, the server side adjusts a transmission rate of the data information according to the length warning information. The invention also correspondingly provides the transmission control system for the screen projection and a readable memory medium. According to the method, the system and the readable memory medium, through establishment of cache queues at the server side and the client side for the screen projection, the frame loss and omission condition of the data information can be effectively avoided, and the fluency of the screen projection is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission control method, system and readable storage medium for screen projection. Background technique [0002] With the development of communication technology, screen projection technology can realize the interconnection between multiple terminals, so that the content displayed on the screen of the transmitting terminal is projected onto the screens of other receiving terminals, so as to realize the function of screen projection. [0003] In practical applications, in order to ensure that the client and the server can achieve real-time synchronous playback of the same information, usually the client generates a frame of data and receives a frame of data on the server. In theory, this can achieve real-time synchronization. However, In practical applications, when a user of a transmission terminal sends data to the client in a conference, and several people view the...
