ABSTRACT:
A digital color video signal is subsampled into a special YUV block format that arranges the data in small groupings of interleaved V, U, and Y values in a left-to-right, top-to-bottom sequence across a video frame. This format results in significantly-reduced hardware memory requirements in the video reception system. Interpolation or dithering is also used to reduce unwanted artifacts in the resulting images.
