Aspect Ratio Terminology
Recent developments in widescreen technology have made the use of Aspect
Ratio Converters Prolific. The industry as a whole has found it necessary to
formalise specifying the format of a picture on a 4:3 or 16:9 monitoring glass
using a sequence of letters and numbers. For example 16F16 is a normal Full
frame Widescreen picture viewed on a widescreen monitor.
Generally the format of the code is as follows:
PPAMM
“PP”
is a number (usually 12,14 or 16) which describes the aspect ratio divided
by 9** of the “Viewable Picture” when viewed correctly (i.e not distorted). Note
this does not include any “Black” which goes to make parts of the picture that
have no picture content (e.g the black of the letterbox).
“A”
is a letter describing the appearance of the “Viewable Picture” within the
Glass Screen. This can be:=
“F”, which means the picture completely fills the screen
“L”, which means the picture is letter-boxed. (Letter-box means there is a black
band at the top and the bottom of the picture).
“P”, which means the picture is pillar-boxed. (Pillar-box means that there is black
to the left and the right of the picture)
“MM”
is a number (usually 12, 16) which describes the aspect ratio divided by
9** of the “Glass”.
(**Note that 16 therefore means 16:9, and 12 means 12:9, which is the same as
4:3.)
An example of a conversion is:
