US Patent 7474236 Method of and apparatus for transmitting digital data

A method of transmitting digital data, with which parallel data, which are constituted with first, second and third data sequences each constituting 12-bit word sequence and multiplexed in parallel with one another to form a digital video signal, are first converted into first and second word sequence data, each of which are constituted with 10-bit words arranged in sequence. Each of the 10-bit words arranged in sequence to form each of the first and second word sequence data does not correspond to a predetermined forbidden code, and consequently, each of the first and second word sequence data do not contain specific 10 bits corresponding to the predetermined forbidden code and therefore can be easily and appropriately reconverted into the original parallel data forming the digital video signal. Then, the first and second word sequence data thus obtained are subjected to P/S conversion to be converted into the first and second serial data, respectively, and the first and second serial data are transmitted.
