Abstract
A screen frame transmission system includes a receiving device and a transmitting device. The receiving device includes a display unit or an external display device for displaying a 2D bar code containing connection information. The transmitting device includes an image capturing unit for capturing an image of the 2D bar code. The transmitting device decodes the 2D bar code to obtain the connection information and establishes a communication connection with the receiving device therewith to transmit a screen frame, thereby simplifying operations of a user.
