Abstract

The invention relates to a method and an apparatus for realizing wired screen transmission. The method includes the following steps: providing more than two communication protocol ports for a first device based on a pre-installed universal driver of the first device, and establishing a USB communication connection between a home terminal and the first device through the communication protocol ports and a first USB interface of the home terminal; when detecting that the first USB interface receives information from the first device, detecting the port transmitting the information, and if the port is a port used for transmitting audio and video data, identifying the information as audio and video data, and playing corresponding audio and video on the home terminal; and acquiring a control signal for the first deice detected by the home terminal, adapting the control signal to the port used for transmitting control signals, and sending the control signal to the first device through the first USB interface. Through the method and the apparatus, wiring for screen transmission can be simplified, and the difficulty of wiring for users can be reduced.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and device for realizing wired screen transmission. Background technique [0002] Screen transfer is realized by computer and other display source devices intercepting the screen pages and sound data of the system, and sending them to the display device, and the display device decodes, displays and plays the sent pictures and sounds. Screen transmission is often used in conferences or teaching fields. Users need to project audio and video signals from the computer to a large-screen LCD electronic whiteboard or projector for display. The audio and video data on the computer are sent to the display device through the corresponding data cable. However, in the traditional screen display mode, the display device is only used for information display, and does not have the function of receiving user operation instructions and sending back the display source, which is ...
