Period of 2 for both the U and V components indicating that U and V samples are taken forĮvery second pixel across a line. For example, UYVY format has a horizontal subsampling The horizontal subsampling interval describes how frequentlyĪcross a line a sample of that component is taken while the vertical interval describes on Subsampling intervals in the horizontal and vertical directions may Indicates the leftmost V sample and Yn indicates the Y sample at the (n+1)th pixel from V sample indicates the sampling position across the image line, so, for example, V0 In the diagrams below, the numerical suffix attached to each Y, U or Into macropixels which are stored in a single array, and the planarįormats where each component is stored as a separate array, the final image being a (Cb) and V (Cr) samples are packed together YUV formats fall into two distinct groups, the packed formats where Y, U
