The HDMI protocol allows the transmission of digital data through video and audio interfaces by moving information through the use of TMDS (transmission minimized differential signaling) from one point to another. TMDS protects the signal being transmitted by encoding it and preventing degradation as it moves down the cable length. With TMDS, high speed serial data is transmitted across DVI (digital video imaging) and HDMI and other digital video interfaces.
