| * \date 6.10.2000, | |
| * \version | |
| * 1.1 | |
| * | |
| * \note | |
| * Version 1.0 included three partition modes, no DP, 2 partitionsper slice | |
| * and 4 partitions per slice. As per document VCEG-N72 this is changed | |
| * in version 1.1 to only two partition modes, one without DP and one with | |
| * 3 partition per slice | |

| * | |
| * \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 | |
| * | |
| * -IMPORTANT: | |
| * Picture- or Sliceheaders must be assigned to partition 0. \par | |
| * Furthermore partitions must follow syntax dependencies as | |
| * outlined in document Q15-J-23. | |
