Along with each frame, it is possible to associate a QP Table specifying, for each encoding block of the frame, the QP you want to use. The QP value can be relative or absolute. The QP table buffer must contain a byte per MB/CTB, in raster scan format:

  1. In AVC, one byte per 16x16 MB
  2. In HEVC, one byte per 32x32 CTB
