you are correct, it is not explicit enough. the encoded residual
is a string of Rice codes of the form 000nnn, where 000 is a unary
portion and nnn is the binary portion of length k, k being the
rice parameter. but there is a signed->unsigned transform before
rice coding that needs to be documented.
