Dynamic range
Dynamic range is the difference between the lowest level of
sound that can be heard above the noise of the equipment and

Dynamic range compression means reducing the gap between
the loudest and softest sounds. This means you can listen at
low volumes but still hear dialog clearly.

Frames and fields
Frames refer to the single images that constitute the video you
see on your television. Each frame consists of two fields.
≥ A frame still shows two fields, so there may be some blurring,
but picture quality is generally better.
≥ A field still shows less picture information so it may be
rougher, but there is no blurring.
