RTV 3511 Lecture Notes - Lecture 10: Ntsc, Patch Panel, Motion Blur
Document Summary
Resolution: how many lines in the frame, analog # of lines 525, with analog, you were better off with a smaller screen due to the lines. Aspect ratio: 4 x 3, basically a square. Modulation changing of electrical current (signal) corresponds to picture and sounds (cid:1) Signal integrity: the most prominent problem with analog. Attenuation: weakening of signal over distance: signal loss, interference (atmospheric, electrical, other frequencies) Modulation assign digital code: binary numbers, 1s and 0s, represent modulations sampling, modulations patterns turns into code, performed 48,000 times per second ss (cid:1) Invariable signal quality: all or nothing, like a light switch. Less bandwidth: simply takes up less space, less info. Computer compatibility: work on a digital platform. Work flow: can do anything with it, put it online, ext. High def has always been digital (in the us) but just because something is digital doesn"t mean its high def: however, high def can be analog.
