This TDMS will help to protect the signal quality and reduce the risk of degradation. As the information is transferred, one of the twisted pairs of the wire carries the signal itself. While the other pairs carry the signal’s inverted duplicate.

This is how you obtain high-quality audio and video. The HDMI can also protect your data from piracy using the HDCP (high-bandwidth digital protection) technology.
