4.4 Digital quantization methods
Replace the existing note after equation (7) by the following new note:
N-8 N-8 N
NOTE Bit levels “from 0 to 2 -1” and “from 255 × 2 to 2 -1” (0 and 255, for the case of 8-bit
encoding) are used exclusively for synchronization and are not allowed for storing colour values. Levels
N-8 N-8
from “2 ” to “255 × 2 -1” (from 1 to 254, for the case of 8-bit encoding) are available.
