Abstract
Digital video signals are transmitted from a transmitter to a receiver via a digital video interface including shielded twisted pair cables that are surrounded by an over-braid shield. The over-braid shield is connected to a chassis ground at a transmitting end and the receiving end. An interface conveys the received signals to receiver processing circuitry. The interface is connected to an isolated ground, isolating the receiver processing circuitry. The twisted pairs are also connected to the isolated ground, such that a return current is forced back through the twisted pair cable shields rather than the over-braid shield. This reduces electromagnetic emissions and confines transients primarily to the over-braid shield.
