Why the name Bibi-binary?

Boby Lapointe described BiBi-binary as a short binary code. Citations (translated):

With the binary code, with 4 digits, get up to 15. With BiBi-binary, get up to 15 ... with 2 letters. [...] In argot bibi means me, my name is Boby and my children call me bibi so it is fun to call this system Bibi. [...] Binary is a base 2 system, bibinary is a base 4 system, bibi-binary is a base 16 system.

Base 4 or Base 16 for Bibi-binary?

BiBi-binary uses 8 characters: 4 vowels O, A, E, I and 4 consonants H, B, K et D. So it is not exactly a base 4 numeric system, but, depending on the parity (odd/even) it uses a vowel or a consonant. This subtlety supports that it is a base 16 writing (hexadecimal).

How to convert binary to Bibi-binary?

Segment the binary code in groups of 2 (from the right)

Example: 110111001 becomes '01, 10,11,10,01 '

Always starting from the right, replace the first group with vowels then the next group with consonants and so on alternately according to the table:

00OH
01AB
10EK
11ID

Example: '01, 10,11,10,01 becomes AKIKA', if the number of letters is not even, complete with an initial H or HAKIKA

When Bibi-binary code was invented ?

A patent has been set in 1968 by Robert Lapointe.
