VCRPlus code, 1 - 6 or 9 digits Day Month Year (last update: 06/05/2000)

(The original example of Ken Shirriff is code 3316, 05/01/1991
my example is code 300-061-798, 05/01/2001)

Final result: I have no chance to check the tables.
I had to take those I found on the Internet!

Step 1:

Minute offset:

Step 2: (compute from right to left!)

           
                    =
                =    
            =        
        =            
    =                
=                    
1. intermediate number:
           
= = = = = =
2. intermediate number:
           
= = = = = =
result:

This step is only needed, if the above result is shorter than the original VCRPlus code:

           
= = = = = =
1. intermediate number:
           
= = = = = =
2. intermediate number:
           
= = = = = =
result:

The following step(s) is(are) only needed, if the above result is still shorter than the original VCRPlus code:

Int. code 1: Int. code 2: result:
Int. code 1: Int. code 2: result:
Int. code 1: Int. code 2: result:
Int. code 1: Int. code 2: result:

 

Intermediate code:

Step 3:

Top (of intermediate code) =
Bottom (of intermediate code) =

Step 4:

Day =
Rem =

Step 5::

Offset =
Amount of repetitions =
1: Top ( = = =) Offset =
2: Top ( = = =) Offset =
3: Top ( = = =) Offset =
4: Top ( = = =) Offset =
5: Top ( = = =) Offset =
6: Top ( = = =) Offset =
7: Top ( = = =) Offset =
8: Top ( = = =) Offset =
9: Top ( = = =) Offset =
10: Top ( = = =) Offset =
11: Top ( = = =) Offset =
12: Top ( = = =) Offset =
13: Top ( = = =) Offset =
14: Top ( = = =) Offset =
15: Top ( = = =) Offset =
16: Top ( = = =) Offset =
Newtop Offset

This step is only needed, if the above result is shorter than the original top:

Newtop Offset

These values are used for further computations:

Newtop Offset

Step 6:

Top2 =

Step 7:

Newtop = t8 c5 t7 c4 t6 t5 t4 c3 t3 c2

 

Top2 = (binary) t2 c1 t1 c0 t0

 

Channelbits = c5 c4 c3 c2 c1 c0 = =
32 16 8 4 2 1

 

Indexbits = t8 t7 t6 t5 t4 t3 t2 t1 t0 =
256 128 64 32 16 8 4 2 1

Step 8::
