/* HS:  This is a very first implementation of the DPB. It shall
        be extended in future in way that it performs exactly the
        same operations as the DPB in standard AVC (including 
        MMCO and RPLR commands). Currently, it simulates the 
        operations of the previous JSVM software version. 
        Furthermore, it is probably necessary that a single DPB is
        used for all "layers" (same dependency_id). With the
        current implementation, a DPB per "layer" is used.
