TV-the grand illusion

Previously, the quality of motion reproduction in television has not been an issue. In the drive towards higher definition, the `definition´ is assumed to be spatial, not temporal. There was no requirement for better motion, that is, unless it was in the context of slow-motion replay, which effectively put motion under the microscope, and is the equivalent of high definition. However, the fact that most coding strategies are affected heavily by motion means that there is a need to understand a lot more about it. Little research has gone into the basics of motion perception, as opposed to the perception of impairments to it caused by compression. The author attempts to lay the groundwork of some theory on this matter. The topics of sampling, the film process and TV systems are discussed
