A pure video signal can be transmitted through various methods, such as using a coaxial cable, HDMI cable, or optical fiber. The video signal is typically generated by a video source, such as a camera or a computer, and then transmitted through the chosen medium to a display device, such as a TV or monitor. The signal is transmitted in its original form without any additional processing or alteration, ensuring that the video quality remains high and true to the original source. **
