What is the main difference between television and cinema (as discussed in the source)?

The main difference between television and cinema lies in the liveness differential.

Television carries a sense of live, present-time transmission that cinema, a recorded form, lacks.

Eye movement describes viewing behaviour and is not the defining contrast between the two media.

Sound resonance concerns audio quality and does not mark the key distinction discussed.

Band width is a technical carrying capacity and is not the essential difference between them.

The liveness differential, television's nearness to the live moment against cinema's recorded distance, is the core distinction.

This connects to the idea of television's nowness against cinema's 'there and then'.
