\subsection{Detailed Description}
A Huffman code for a Theora D\+CT token.
Each set of Huffman codes in a given table must form a complete, prefix-\/free code. There is no requirement that all the tokens in a table have a valid code, but the current encoder is not optimized to take advantage of this. If each of the five grouops of 16 tables does not contain at least one table with a code for every token, then the encoder may fail to encode certain frames. The complete table in the first group of 16 does not have to be in the same place as the complete table in the other groups, but the complete tables in the remaining four groups must all be in the same place.
