Si le c\u00e2ble est plus long que 20 m\u00e8tres, il est important que le fil qui transporte le signal vid\u00e9o soit blind\u00e9 contre les influences des autres fils. Cela se r\u00e9sout en utilisant un c\u00e2ble coaxial. Le signal vid\u00e9o passe alors par l&rsquo;\u00e2me du c\u00e2ble coaxial. La gaine autour de cette \u00e2me (qui est dans une gaine plastique) est en m\u00e9tal et peut servir \u00e0 transporter la tension n\u00e9gative (GND) et garantit que le signal vid\u00e9o est blind\u00e9 et reste bon.
