TMDS - Computer Definition
(Transition Minimized Differential Signaling) A transmission method for sending digital information from a personal computer, set-top box or other video source to a flat panel display. Developed by Silicon Image, Sunnyvale, CA (www.siliconimage.com), it is used in DVI and HDMI interfaces, as well as in displays supported by the earlier VESA Plug and Display and DFP interfaces. TMDS is based on low-voltage differential signaling and converts an 8-bit signal into a 10-bit transition-minimized and DC-balanced signal (equal number of 0s and 1s) in order to reduce EMI generation and improve reliability. See DVI, LVDS and flat panel display.
