Abstract
Digital standards conversion from one T.V. line standard to another including a processor for synthesizing picture points from adjacent picture point information derived from video signals from at least one field and a digital persistence arrangement for effecting movement interpolation between incoming and stored information. The digital persistence may be cylically varied field by field as well as being variable in dependence on any picture movement detected.
