In TV transmission, a picture is converted into an electrical signal through a process called scanning, where a camera captures the image and breaks it down into pixels. These pixels are then encoded into a signal that can be modulated and transmitted over the airwaves or via cable. At the receiving end, the signal is demodulated and decoded, reconstructing the original picture for display on a television screen. This process occurs rapidly, typically at rates of 30 frames per second or higher, to create smooth motion.

How is a picture produced with the ultrasound machine?
It's very similar to the depth finder on a boat...sound waves are transmitted to the target and the "depth" determined from timing the return of the echo. This is in turn converted into a picture by computer software. I hope this makes sense to you.
Do new video cables really make a difference in the quality of picture?
Video cables stream information to the Television. The higher quality of the video cables, the more information will be transmitted per second to the television, resulting in a higher quality picture.
