This paper presents an error correcting algorithm based on HDMI coding character,which can fix many errors when the data transmit through the HDMI channel.This new algorithm uses failure analysis to evaluate the error possibilities of each possible error;analyses the error characteristic and sort the most similar source,and then corrects it.It can also be combined with BCH code in the HDMI system to improve the reliability of HDMI transmission.However,the algorithm has some limitations:there are different re-pair rates in different stages of HDMI data transmission.An ASIC design of the algorithm is given in this article using Verilog HDL language for RTL level design,and its feasibility is proved by function simulation,verification and synthesis.
