I think you mis-understood what he said and meant; when he said times <= N, I think he meant that you can replace the continuous and unbounded t in a(t) and b(t) by some finite set t_1, r_2, ..., t_N and work with the discrete version of the problem. After doing that, you can pass to the continuous limit.
