Abstract
An encoding scheme simplifies the TMDS encoding algorithm described in the DVI 1.0 specification while retaining compatibility with most existing DVI receivers. The generation of the Transition Control bit has been removed; and although the INV bit has a similar function to the DC bit in the DVI 1.0 standard, the algorithm for deriving it is very different. No attempt is made to maintain a DC balance on the cable. Instead, the INV bit is set to a '1' for the purpose of removing 'rogue' character sequences; otherwise it is always set to a ‘0’.
