SCANNING SYSTEM

TV signal transmission system is point to point and make a line by line by an electron beam (Electron Beam) or light Kathoda (Cathode beam) as read from left to right and once to the right side must be left back again quickly and shifted vertically downward read the following sentence under it, so after the end of the sentence until the bottom side must get back quickly onto the next page to read the sentence. At the time of re-moving horizontally from right-left and from below upwards, the electron beam is extinguished. Before the era of television technology have been known Media Movie Theaters that use the big screen, compared with Vertical Horizontal size is 2: 1 or more technical term is Aspect Ratio (H / V) = 2 / 1, taken from the characteristics...

CHARACTERISTICS OF HUMAN EYES

Similarly, the characteristics of the human eye which is the basic principle to the establishment of TV technology, among others: The human eye can not follow the movement of the light source is moving very fast, eg in a dark room a light source (Flashlight or small flashlight, mosquito coil ignition, flame or smoking)            when driven slowly will be seen as a point of light, but when he moved very quickly then it will be seen as light lines corresponding movement. Human eyes can not see the flashing light source 20 times per second, Lighting Lamp TL example blink as much as 50 x per second. Human eyes can not see the change of moving images as much as 16 pictures per second, examples of film technology that uses the turn of the Frame as many as 24 frames...
