Description (last modified by ksuehring)

The paragraph just before E.3.2 section says:

log2_max_mv_length_horizontal and log2_max_mv_length_vertical indicate the maximum absolute value of a decoded horizontal and vertical motion vector component, respectively, in quarter luma sample units, for all pictures in the CVS. A value of n asserts that no value of a motion vector component is outside the range of −2n to 2n − 1, inclusive, in units of quarter luma sample displacement. The value of log2_max_mv_length_horizontal shall be in the range of 0 to 16, inclusive. The value of log2_max_mv_length_vertical shall be in the range of 0 to 15, inclusive. When log2_max_mv_length_horizontal is not present, the values of log2_max_mv_length_horizontal and log2_max_mv_length_vertical is inferred to be equal to 15.

What "n" here stands for?

To me that statement doesn't seem very likely to be misinterpreted, but I agree that a different phrasing would be desirable.

"n" refers to the value of log2_max_mv_length_horizontal and log2_max_mv_length_vertical for the horizontal and vertical component of the MV, respectively.

I was about to write a similar reply.
