Webmore data bits must be transmitted within the same time frame, thus requiring an increase in data rate and TMDS clock. The factor by how much the TMDS clock must increase is given by the ratio of deep color mode (n-bit/pixel)to standard color mode (24-bit/pixel).Table 2 lists the various color depths and their corresponding multiplying factors. WebNov 1, 2024 · HDMI 2.0 increases the transition-minimized differential signaling (TMDS) character rate from 340 to 600 Mega characters per second (Mcsc) over previous versions, and also adds scrambling for EMI/RFI for different rates. The relation in TMDS clock rate, bit rate, and character rates below 340 Mcsc or above 340 Mcsc, is shown in below table.
