最小化传输差分信号（Transition Minimized Differential Signaling，简称TMDS）是美国Silicon Image公司开发的一项高速传输数据技术，可用于DVI与HDMI的影像传输接口。

TMDS差分传输技术是一种利用2个引脚间电压差来传送信号的技术，TMDS具备4个Channel，前3条缆线分是YU（Pb）V（Pr）的传输线，或视为 RGB的传输线，第4条是Clock，以保证传输时所需的统一时序, 总称为１个连接或 Single-link。每个信道最大传输速度是165MHz(4.95 Gb/s)，１个连接有5Gbps的传输速度。MDS解码之后的原始数据被HDCP加密。并采用了8b/10b差分信号来降低EMI及提高精确的信号传输速率，将8比特的输入信号转换成10比特的编码。

Transition-minimized differential signaling (TMDS), a technology for transmitting high-speed serial data, is used by the DVI and HDMI video interfaces, as well as by other digital communication interfaces.

The transmitter incorporates an advanced coding algorithm which reduces electromagnetic interference over copper cables and enables robust clock recovery at the receiver to achieve high skew tolerance for driving longer cables as well as shorter low-cost cables.
