Abstract
The relationships between motion and television signal deterioration are explored for one of the two television coding schemes currently most used, i.e., PAL. The relevance of motion issues is related to the fact that, to a given extent, for PAL and NTSC (and in general for fixed bit-rate image coding schemes), television signals quality becomes worse as the motion content of the scene increases. The motion-dependent aliasing of sampled spatio-temporal signals is reported
