  1. Support of 8K15 uses a subset of level 6: maximum Luma picture size up to 225 samples, other constraints of Level 5.1 apply (e.g., maximum of 200 slices and 11×10 tiles), WPP is not supported for widths above 4,096.
  2. Support of 8K15 uses a subset of Level 6: maximum Luma picture size up to 225 samples, other constraints of Level 5.2 apply, maximum slice size of 65,535 macroblocks so a minimum of two balanced slices must be used above 4K size.

The following table describes the VDU maximum supported bit rates.
