| * \brief lookup-table to assign different elements to partition |
| * |
| * \note here we defined up to 6 different partitions similar to |
| * document Q15-k-18 described in the PROGFRAMEMODE. |
| * The Sliceheader contains the PSYNC information. \par |
| * |
| * Elements inside a partition are not ordered. They are |
| * ordered by occurence in the stream. |
| * Assumption: Only partitionlosses are considered. \par |
| * |
| * The texture elements luminance and chrominance are |
| * not ordered in the progressive form |
| * This may be changed in image.c \par |
| * |
| * We also defined the proposed internet partition mode |
| * of Stephan Wenger here. To select the desired mode |
| * uncomment one of the two following lines. \par |
| * |
| * -IMPORTANT: |
| * Picture- or Sliceheaders must be assigned to partition 0. \par |
| * Furthermore partitions must follow syntax dependencies as |
| * outlined in document Q15-J-23. |
