Most everyday meetings today involve presenters connecting their computers to a shared TV or projector via HDMI during their turn. This requires the hassle of switching HDMI connections every time a presenter changes, and it also limits the ability to view multiple presenters' screens simultaneously. This paper proposes and implements a Multiplexer System that allows presenters to easily share displays. This system is a form of display sharing that connects the presenters' screens to a general-purpose multiplexer computer that is directly connected to a large display and is connected in real time. We used WebRTC to handle real-time transmission of screen images, and leveraged the hardware video decoder built into the multiplexer computer for fast decoding of encoded streams. To evaluate the performance of the Multiplexer System, we measured the screen latency required for the screen image of the presenter's computer to be displayed on the multiplexer's display. The result was evaluated to be around 221-362 ms when the number of simultaneous presenters is two, which is considered to be a level that does not cause any inconvenience to the presenters. We conclude that the Multiplexer System proposed in this paper is a system that conveniently supports everyday meetings without the use of special hardware or additional costs.
