#1201 closed defect (fixed)

Minor corrections to Range Extensions

Reported by: peterderivaz Owned by:
Priority: minor Milestone: RExt D5
Component: RExt text Version: RExt D5 (O1005) v1
Keywords: Cc: davidf, joel, teruhiko, jct-vc@…


In O1005v1 there are the following minor errors:

  1. In 8.4.4 "Derivation process for block vector components in intra block copying prediction mode", the text uses x0,y0 which are undefined in this process. (Probably xCb, yCb are correct)
  1. In "General decoding process for intra blocks" the variables xCb,xB0,yCb,yB0 are used to access explicit_rdpcm_dir_flag, but none of these variables are defined in the process
  1. Table 9-4 mentions "explcit_rdpcm_dir_flag[ ][ ][ 0 ]" instead of "explicit_rdpcm_dir_flag[ ][ ][ 0 ]"
  1. Table 9-34 mentions "= chroma_qp_adjustment_table_size_minux1" instead of "= chroma_qp_adjustment_table_size_minus1"
  1. Equation 7-33 uses "Log2MinCuQpChromaAdjustmentSize" instead of "Log2MinCuChromaQpAdjustmentSize"
  1. intra_bc_flag is not mentioned in Table 9-39 (all other arithmetic coded symbols are in this table)

Another minor correction to add to the list:

In CuPredMode[xC][yC] is accessed. This should probably be CuPredMode[x0][y0] or perhaps CuPredMode[x0+xC][y0+yC].

  • Resolution set to fixed
  • Status changed from new to closed

All of the above (1--7) have been fixed in v2.


  1. use {x,y}Cb
  2. see also #1208 for more general issue
