INHDMI devices do not just send video automatically. Before anything displays, the source checks what it is connected to and looks for a valid EDID handshake, which is the digital identity a TV sends to confirm it is a legitimate display.
In this video, they are removing a video decoder chip from the circuit board because it contains a working EDID key stored inside. That key can be reused so another device can impersonate a real television instead of being detected as an unlicensed capture card or restricted recording device.
Once that chip is salvaged, it can be installed into other hardware to force the handshake to succeed and unlock normal video output. It is a small component, but it controls a critical part of modern video security and compatibility.
