Abstract

The invention provides a wireless projection control method and a wireless projection control system. The control method comprises the following steps: at least one operation limit is set; a transmitting device communicates with a receiving device or a communication device, so that the transmitting device or the receiving device performs at least one limited operation; and after the transmitting device or the receiving device executes at least one limited operation, the receiving device selectively or limitedly projects the image signal to the display device. The transmitting device is used for selectively transmitting the image signal generated by the communication device to the receiving device according to at least one operation limit.

Description

technical field [0001] The present invention relates to a control method of wireless projection and a control system of wireless projection, in particular to a control method of wireless projection and a control system of wireless projection which use high-security key data to transmit data with different authority settings . Background technique [0002] With the rapid development of science and technology, various projector systems and conference report systems have been developed rapidly and are also used in daily life. The conference report system can be combined with a projector system to increase the convenience of the presenter when presenting materials. Most of the current conference report systems use the wireless communication data transmission method as the mainstream. The data transmission mode of wireless communication can be divided into two modes. In the first mode, the computers used by the members participating in the meeting must be equipped with specifi...
