your tv set changes the television signals back into pictures and sound. it picks up the thin lines that the tv camera scanned and uses pats called electron guns to paint one thin line at a time. the lines get painted from top to botton. a colour tv set uses three electron guns to beam out three colors--red,green,and blue.the beams scan fast enough to paint a piuture on your screen 30 times a secnd

piuture改为picture secnd改为second 展开
