Detailed Description

Header file for elements in H.264 streams.

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

Variable Documentation

int* assignSE2partition[2]

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.

Elements inside a partition are not ordered. They are ordered by occurence in the stream. Assumption: Only partitionlosses are considered.

The texture elements luminance and chrominance are not ordered in the progressive form This may be changed in image.c

-IMPORTANT: Picture- or Sliceheaders must be assigned to partition 0.

Furthermore partitions must follow syntax dependencies as outlined in document Q15-J-23.
