METHOD, SYSTEM AND RECEIVING DEVICE FOR TRANSMITTING SCREEN FRAMES FROM ONE TO MANY TERMINALS

摘要

A method for transmitting screen frames from one to many terminals is applied to a network system consisting of a first electronic device, a second electronic device, and a third electronic device. The method includes the following steps: the first electronic device transmitting a full screen frame and at least one rectangle data to the second electronic device via network packets, wherein the rectangle data is information of changed areas in the full screen frame; the second electronic device receiving the full screen frame and the rectangle data, and in accordance with each received network packet transmitting an acknowledgement; and the third electronic device intercepting the full screen frame and the rectangle data to reconstruct an updated screen frame for display. A system and a receiving device for transmitting screen frames from one to many terminals are disclosed simultaneously.
