Unique layers of video transmission and storage Every present their very own set of formats to choose from.
In interlaced video, the horizontal scan lines of each total body are treated as though numbered consecutively and captured as two fields: an odd discipline (higher area) consisting of the odd-numbered lines and an even area (lessen industry) consisting on the even-numbered strains.
