Digital video data is transmitted from a video source (61) to a video sink (62) as a group of three multilevel symbols (611, 612, and 613) per pixel color with each associated symbol being sent at a rate of three times the pixel clock (601). When eleven levels are used per symbol (611) and undesirable symbol groups having excess DC residual or minimal energy are eliminated, and a built-in-test symbol group is added for pixel alignment; there results a one-to-one correspondence between the remaining symbol groups available and the two-hundred and sixty possible states that are used in the TMDS physical layer that is in widespread commercial use.
