Transition-minimized differential signaling

Of the 1,024 possible combinations of the 10 transmitted bits: Control data is encoded using the values in the table below.

TMDS was developed by Silicon Image Inc. as a member of the Digital Display Working Group.

TMDS also uses a twisted pair for noise reduction, rather than coaxial cable that is conventional for carrying video signals.

The physical layer for TMDS is current mode logic (CML),[2] DC coupled and terminated to 3.3 Volts.

TMDS can be switched or repeated by any method applicable to CML signals.
