6.4.2 Aspect ratio
Aspect ratios
The standard aspect ratio used in broadcast television is the 4:3 ratio. However, most of the DVD sources use nowadays the
widescreen 16:9 or even the cinemascope 2.35:1 aspect ratio.
Some DVD sources may even use the anamorphic 16:9 or anamorphic 2.35:1 to take advantage of the higher vertical resolution
offered by the 4:3 ratio. The “anamorphic” term means that the original widescreen image is squeezed in order to fit the 4:3 aspect
ratio.
