Skip field
In video, skip field recording is a process in which only one field of video is recorded in order to conserve recording media space. In some cases, the quality loss from not using both fields is negligible, although it leads to a reduction in vertical and temporal resolution. It was a common method used in early telerecording systems, as well as early and current non-professional/industrial videotape formats such as CV-2000, Cartrivision and V-Cord.
