5. The method as defined in claim 1 , wherein the method further comprises: detecting a difference between the trick mode frame rate as calculated and a current trick mode frame rate V i−1 related to a semantic occurrence in time interval T i−1 ; and when a magnitude of said difference exceeds a determined threshold, varying a trick mode frame rate for the i th semantic occurrence from said current trick mode frame rate V i−1 to the trick mode frame rate V i as calculated during display of the i th semantic occurrence.
6. The method as defined in claim 5 , wherein said changing is performed in a manner selected from the group consisting of stepwise, stepwise linear, stepwise nonlinear, and uniformly equal stepwise increments.
