The symbolic forms that contain the codes and syntax of media communication result in media

The symbolic forms that carry the codes and syntax of media communication result in media grammar.

Just as language has rules that organise words into meaning, media grammar is the system of conventions organising images, sounds and edits.

It is the underlying structure of codes and arrangement through which a medium makes its messages intelligible.

Sub-text refers to an implied or hidden meaning beneath the surface, not to the organising rule-system of codes and syntax.

Sense denotes the meaning that is finally grasped, which is a product of the grammar rather than the code-and-syntax structure itself.

Semiotics is the broader study of signs and signification, a field of analysis, not the specific rule-set of codes that this description names.
