[0002] The USB interface is a data communication interface widely used in modern electronic devices. It supports plug-and-play and hot-swap functions, allowing users to easily connect various devices such as keyboards, mice, printers, external storage devices, etc.

[0003] However, as the USB interface evolved from versions 1.0 / 1.1 / 2.0 / 3.0 / 4, while transmission speed specifications significantly improved, particularly with the introduction of ultra-high-speed transmission (bandwidth exceeding 5Gbps) starting with USB 3.0, transmission distance became an increasingly prominent issue. With high bandwidth demands, achieving long-distance transmission became a major challenge, limiting USB's use in applications such as large printers, medical equipment, multimedia classrooms and exhibition screens, and high-definition industrial cameras for data acquisition and monitoring. Furthermore, the USB interface itself does not support direct output of video signals, necessitating additional conversion equipment for image display. Traditional USB extenders on the market primarily extend USB data signals, while HDMI video extenders are specifically designed to extend video signals. These two products exist independently. Because they cannot simultaneously process both USB data and video signals, these single-signal processing devices exhibit limitations in practical applications. To meet different signal extension requirements, users must purchase and maintain multiple devices, which not only increases costs but also complicates engineering and wiring.
