이 연구에서는 스마트 HDMI 스위치를 제안하는데, HDMI 플러그를 물리적으로 빼고 다시 껴는 일이 없는 상태에서 새로이 형성되는 비디오 스트림을 감지해서 자동적으로 전송 경로를 해당 포트로 전환해 주는 것이 주된 내용이다. 더 나아가 제안하는 시스템은 밀리미터 밴드 기술을 기반으로 진보된 무선 비디오 전송 구조 안에서 설계되었다. 하드웨어 실험을 통해서 제안된 시스템이 스마트 포트 전환 기능을 포함하는 가운데 풀 HD 비디오 전송 성능을 갖는 것을 보임으로써 그 유용성을 확인하였다.

The recent development of information and communication technology has a great impact on the audio/video industry. In particular, IP-based AoIP transmission technology and AVB technology are making changes in the audio/video market. Video signal transmission technology has been introduced to the market through a network, but it has not replaced the video switcher function. Video signals in the conference room or classroom are still controlled by the switching device. In order to switch input/output video devices, a cable that is not limited by distance must be connected to the switcher. In addition, the control of the switching device must be performed by a person who has received professional training. In this paper, it is a technology that can be operated even by non-experts by replacing complex video cables (RGB, DVI, HDMI, DP) with LAN cables and enabling IP-based video switching and transmission (Video Mirroring over IP: VMoIP) to replace video switcher equipment. We are going to do this study, I/O videos were controlled in the form of matrix and high-definition videos were transmitted without distortion, and VMoIP is expected to become the standard for video switching systems in the future.
