color upsampling error (CUE)

Color Upsampling Error (CUE) or Color Upsampling Bug is an error that has partially survived in early generation DVD players to this day. In the case of the CUE error, the colour signals of the even and odd lines were swapped from the YCbCrvideo signal stored on the DVD with 4:2:0 colour subsampling due to an error in the extrapolation to the 4:2:2 format, which leads to horizontal edge noise in corresponding picture content.
