* This is the H.26L decoder reference software. For detailed documentation
* see the comments in each file.
*
* \author
* The main contributors are listed in contributors.h
*
* \version
* JM 6.1d
*
* \note
* tags are used for document system "doxygen"
* available at http://www.doxygen.org
*
* \par Limitations:
* Using different NAL's the assignment of partition-id to containing
* syntax elements may got lost, if this information is not transmitted.
* The same has to be stated for the partitionlength if partitions are
* merged by the NAL.
* \par
* The presented solution in Q15-K-16 solves both of this problems as the
* departitioner parses the bitstream before decoding. Due to syntax element
* dependencies both, partition bounds and partitionlength information can
* be parsed by the departitioner.
*
* \par Handling partition information in external file:
* As the TML is still a work in progress, it makes sense to handle this
* information for simplification in an external file, here called partition
* information file, which can be found by the extension .dp extending the
* original encoded H.26L bitstream. In this file partition-ids followed by its
* partitionlength is written. Instead of parsing the bitstream we get the
* partition information now out of this file.
* This information is assumed to be never sent over transmission channels
* (simulation scenarios) as it's information we allways get using a
* "real" departitioner before decoding
*
* \par Extension of Interim File Format:
* Therefore a convention has to be made within the interim file format.
* The underlying NAL has to take care of fulfilling these conventions.
* All partitions have to be bytealigned to be readable by the decoder,
* So if the NAL-encoder merges partitions, >>this is only possible to use the
* VLC structure of the H.26L bitstream<<, this bitaligned structure has to be
* broken up by the NAL-decoder. In this case the NAL-decoder is responsable to
* read the partitionlength information from the partition information file.
* Partitionlosses are signaled with a partition of zero length containing no
* syntax elements.
