Description

The attached file suggests solutions for bugs and typos in the syntax and specification text related to coefficients coding. Below is a summary of the suggested changes:

  • numSigCoeff is removed, since it does not seem to be used anymore
  • A couple of typos are fixed in the first and second loops for coefficients coding
  • Section 9.5.3.2 Rice parameter derivation process for dec_abs_level[ ] is fixed

Many thanks to Heiko for having a look at the suggested changes.

After further discussions with Heiko, some more fixes have been included:

  • In the definition of firstPosMode0 in the syntax
  • In the conditions for coding of sig_coeff_flag
  • Replaced checking if sig_coeff_flag is equal to 1 by checking if AbsLevel is greater than 0, since sig_coeff_flag is not signalled for all coefficient positions
