Skybuck's universal code
I have updated this section to prevent any further confusion:
" Data bits: a,a,a,a,a,a,b,b,b,b,b,c,c,c,c (these bits can have value 0 or 1) " (Since some people though these aaaa, bbb, ccc bits behaved like unary encoding (all ones or all zeros) This is not the case. These bits can have any binary value, a zero or a one. I have also included a new part for further clearity: New part: " The position of the bit in the information stream identifies if it is a marker bit or a data bit. Positions: 0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,2,2,2,2,2, 2,2,2,2,2 0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4, 5,6,7,8,9 Information stream: a,0,a,0,a,0,a,0,a,0,a,1,b,0,b,0,b,0,b,0,b,1,c,0,c, 0,c,0,c,1 The data bits are located on "even" positions. (0,2,4,6,8,10,12,14,16,18,20, etc ) The marker bits are located on "oneven" positions. ( 1,3,5,7,9,11,13,15,17,19, etc ) By reading a data bit, marker bit, data bit, marker bit, etc they can be seperated from each other. " Bye, Skybuck. |

Hi,
And finally what better way than to explain it with an example " An example: Data bits for field A = 1,0,0,0,1,0 Data bits for field B = 1,1,1,0,1 Data bits for field C = 1,0,0,1 Market bits for field A = 0,0,0,0,0,1 Market bits for field B = 0,0,0,0,1 Market bits for field C = 0,0,0,1 Data bits and marker bits interleaved for field A: 1,0,0,0,0,0,0,0,1,0,0,1 Data bits and marker bits interleaved for field B: 1,0,1,0,1,0,0,0,1,1 Data bits and marker bits interleaved for field C: 1,0,0,0,0,0,1,1 Interleaved field A,B,C stuck together (final encoded bitstream): 1,0,0,0,0,0,0,0,1,0,0,1,1,0,1,0,1,0,0,0,1,1,1,0,0, 0,0,0,1,1 " Bye, Skybuck |
