|

* VLADIMIR Z. MESAROVIC , RAGHUNATH RAO, MIROSLAV V. DOKIC, and SACHIN DEO
|
|

* AES paper 5436
|
|

*
|
|

* 2 methods are used for huffman decoding:
|
|

* - binary search
|
|
||||||
* - 2-step table lookup
|
|
||||||
*
|
|
||||||
* The choice of the "optimal" method is based on the fact that if the
|
|
||||||
* memory size for the Two-step is exorbitantly high then the decision
|
|
||||||
* is Binary search for that codebook. However, for marginally more memory
|
|
||||||
* size, if Twostep outperforms even the best case of Binary then the
|
|
||||||
* decision is Two-step for that codebook.
|
|
||||||
*
|
|
||||||
* The following methods are used for the different tables.

/* RVLC scalefactor decoding
|
|
||||||
*
|
|
||||||
* RVLC works like this:
|
|
||||||
* 1. Only symmetric huffman codewords are used
|
|
||||||
* 2. Total length of the scalefactor data is stored in the bitsream
|
|
||||||
* 3. Scalefactors are DPCM coded
|
|
||||||
* 4. Next to the starting value for DPCM the ending value is also stored
|
|
||||||
*
|
|
||||||
* With all this it is possible to read the scalefactor data from 2 sides.
|
|
||||||
* If there is a bit error in the scalefactor data it is possible to start
|
|
||||||
* decoding from the other end of the data, to find all but 1 scalefactor.
