Claim 8:
9. The method according to claim 8, wherein
the run-length value N0 is mapped to a level value ax, wherein the level value ax is a level value with a largest distribution probability among the n values of the level values; and
the odd-numbered run-length values in the run-length value sequence are respectively mapped to the first group of level values, wherein sequence numbers of the first group of level values in the level value sequence are less than x; and the even-numbered run-length values other than the run-length value numbered 0 in the run-length value sequence are respectively mapped to the second group of level values, wherein sequence numbers of the second group of level values in the level value sequence are greater than x, and x is a non-negative integer; or
the even-numbered run-length values other than the run-length value numbered 0 in the run-length value sequence are respectively mapped to the first group of level values, wherein sequence numbers of the first group of level values in the level value sequence are less than x; and the odd-numbered run-length values in the run-length value sequence are respectively mapped to the second group of level values, wherein sequence numbers of the second group of level values in the level value sequence are greater than x, and x is a non-negative integer.
