Distinctive layers of video transmission and storage Each individual present their own personal list of formats from which to choose.
In interlaced video, the horizontal scan strains of each full frame are addressed just as if numbered consecutively and captured as two fields: an odd field (higher discipline) consisting on the odd-numbered lines and a fair discipline (reduced area) consisting with the even-numbered strains.
