Information Transmission Method and Wireless Display System

摘要

An information transmission method is utilized in a wireless display system and the wireless display system includes a source terminal and a sink terminal establishing a wireless connection with each other. The information transmission method includes the sink terminal receiving and displaying frame information transmitted from the source terminal by a data channel and obtaining an operation information; the sink terminal generating a control information according to the operation information and transmitting the control information to the source terminal by a user input back channel; the source terminal performing a command in the control information to output a result information; and the source terminal determining whether to adjust the result information to a display information with a smaller amount of information according to a transmission setting corresponding to the command in the control information and transmitting the display information to the sink terminal by the data channel.
