Description

There is around (7-76) equation in the JCTVC-R1013_v6

last_sig_coeff_x_prefix specifies the prefix of the column position of the last significant coefficient in scanning order within a transform block. The values of last_sig_coeff_x_prefix shall be in the range of 0 to ( log2TrafoSize << 1 ) − 1, inclusive.
last_sig_coeff_y_prefix specifies the prefix of the row position of the last significant coefficient in scanning order within a transform block. The values of last_sig_coeff_y_prefix shall be in the range of 0 to ( log2TrafoSize << 1 ) − 1, inclusive.

it looks like ( 1 << log2TrafoSize ) − 1 should be there

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

For coding of the last significant coefficient position, the prefix specifies the length of the suffix, and the two are then used to specify the actual last significant position (for X and Y).
