Pixels: Each image is made up of thousands of tiny pixels and the more pixels you have the better quality of the image, which is also known as the resolution.
TV motion: Your brain puts today the still images and dots to make it look like a smooth image and there are around 25 still frames every second used in British TV.
TV screen: When an image is put onto your TV screen, the camera splits up every frame into horizontal ‘scan lines’, which are then layered onto the screen when it is received. However different counties use a different amount of ‘scan lines’ per second for each frame. The average in the UK is 525 ‘scan lines’
