ESP-KVM

The ESP-KVM system functions by capturing a digital video signal from a target computer and streaming it securely over a local network to a standard web browser. At the heart of the hardware setup is an ESP32-P4 development board paired with a TC358743 HDMI-to-CSI capture board. The target machine's video output connects via an HDMI cable directly into the TC358743 capture board, which translates the HDMI TMDS data streams into a MIPI CSI-2 camera serial interface format. This CSI-2 stream is fed via a ribbon cable directly into the ESP32-P4 processor, which handles the necessary image processing and video encoding tasks. Once encoded, the video frames are served over the network using the ESP-KVM firmware, allowing an administrator to view the remote machine's display in real time via a web browser. Additionally, the system integrates ATX power control optocouplers connected to the target computer's motherboard headers. These optocouplers provide electrical isolation while allowing the ESP32-P4 to safely trigger power, reset, and status functions remotely. Because this hardware interaction occurs entirely at the physical video and power interface level, it operates completely independently of the target machine's operating system, granting uninterrupted access even during pre-boot BIOS configuration or system crashes.
