The central control module controls the server to distribute the adaptive audio and video data to the data receiving client according to the network quality of the data receiving client, prevents the data receiving client from being incapable of effectively receiving the data due to poor network, and reduces the operation calculation force of the data receiving client through the processing of the server, thereby ensuring the real-time performance of data transmission and ensuring the effective operation of a video conference.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
