Abstract: One approach commonly used in the design of advanced television (ATV) systems, that of spatiotemporal subsampling, provides high static spatial resolution at the cost of reduced dynamic spatial resolution. This article describes the results of two psychophysical experiments which demonstrate that the viewer's visual spatial acuity for the stationary and moving portions of a television program depend critically upon the patterns of eye movements the viewer employs while watching the program. It is concluded that, if an appropriate balance of static and dynamic resolution is to be achieved in ATV, it will be necessary to be able to predict the patterns of eye movements likely to occur during viewing. A brief description of preliminary results from a study of eye movements during program viewing is presented.
