Patent ID: 6912008

Claim:
A method of adding auxiliary data to a serial video data stream comprising the steps of: generating a data stream in sequential groups of N 10-bit words, wherein each 10-bit word comprises 8 video data bits (S 0 -S 7 ) and a most significant bit (S 9 ), and further wherein N is an integer greater than one; combining the most significant bit (S 9 ) associated with first 10-bit word in each group with an auxiliary data bit (Xm) to generate the most significant bit (S 9 ) associated with the second and each subsequent 10-bit word in each group; and combining the video data bits (S 0 -S 7 ) associated with each 10-bit word in each group of N 10-bit words with the respective most significant bit (S 9 ) associated with each 10-bit word in each group of N 10-bit words to generate a resultant data stream.
