Abstract

The invention relates to a method and an apparatus for realizing wired screen transmission. The method includes the following steps: providing a plurality of communication protocol ports for a first device through a first USB interface of a home terminal, and establishing a USB communication connection between the home terminal and the first device through the communication protocol ports and thefirst USB interface, wherein the communication protocol ports can be identified by the universal driver of the first device; when detecting that the first USB interface receives information from the first device, detecting the communication protocol port transmitting the information, and if the communication protocol port is a port used for transmitting audio and video data, identifying the information as audio and video data; forwarding the audio and video data to a second device through a second USB interface of the home terminal; and when detecting that the second USB interface receives a control signal from the second device, 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 present invention relates to the field of data transmission technology, in particular to a method and device for implementing wired screen transmission. Background technique [0002] The implementation of screen transfer is that the display source device such as a computer intercepts the screen page and sound data of the system and sends it to the display device. The display device decodes and displays and plays the sent picture and sound. Screen transmission is often used in conferences or teaching fields. Users need to project the audio and video signals of the computer to a large-screen LCD whiteboard or projector for display. The audio and video data on the computer is sent to the display device through the corresponding data line. However, in the traditional screen display mode, the display device only serves as an information display function, and does not have the function of receiving user operation instructions and returning the display source,...
