 - The first 2 values are stored using the same code as the block length code.[[BR]]
 - The next values are coded as :[[BR]]
 code = value(n) - 2*value(n-1) + value(n-2)[[BR]]
-the 1 bit is sent for code sign, and the absolute value of code is sent as golomb code with k=10. A log code, as Fibonacci or Elias may be better, but golomb is easier to implement.
