Abstract: A video encoder and decoder are described. The encoder operates on luma data and chroma data. The luma data is split into two channels. The channel split can be based on frequency regions or based on even and odd lines. When the channel split is based on frequency regions, the encoder produces a channel with low frequency data and a channel with high frequency data. A third channel holds chroma data. The decoder recovers the split luma data and the third channel of chroma data. The decoder may then generate one or more pixels to be stored in a line buffer.
