Are you wanting to display the centre portion of a 16:9 picture on a 4:3 set?
If so, then ZOOM is the setting you need.
Problem is, you need to be able to control the amount of ZOOM, so that you can 'zoom-in' until the top and bottom edges of the picture just fill the mask.
At this point, you have the full height of the scene, and have lost the minimum of the width.
This is how they used to transmit 'widescreen' films in 4:3 days. They would 'squash' the picture while the opening credits were running, then switch to just the middle 4:3 section for the action.
On extreme widescreen, such as CINERAMA, a TK operator would physically shift the transmitted portion of the picture left and right, to centralize the action.
(This is the job I wanted to do, as a kid).
