Default 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
