Abstract

The present invention provides a video transmission apparatus including an input terminal input with a video signal; an output terminal wire connected to a video device; a wireless communication unit for modulating the video signal through a predetermined wireless modulation method and wirelessly transmitting the modulated video signal; an output switch unit, connected with the input terminal, the output terminal, and the wireless transmission unit, for switching an output destination of the video signal input from the input terminal to the output terminal or the wireless transmission unit; and a switch controller for causing the output switch unit to switch the output destination of the video signal in response to a switch request when receiving the switch request of the output destination by the wireless communication unit.

Description

technical field [0001] The invention relates to a video transmission device and a method for controlling switching of output destinations through the video transmission device. Background technique [0002] In recent years, it has been common to see a situation where a speaker uses a personal computer (PC) to present material to listeners during conferences and public lectures. In such cases, a projector cable connected to the PC is often used. A speaker connects a PC to a DVI (Digital Visual Interface) terminal arranged at a projector with a cable, and gives a lecture while operating the PC at a position where the cable can reach. In some cases, an assistant operating the PC is arranged in addition to the speaker. In this case, the lecturer gives a lecture near the screen on which the screen content of the PC is projected. [0003] Accordingly, projectors have been used to project video on large screens and present information to large numbers of people. However, recent...
