Abstract
Disclosed is an apparatus () for generating a second compressed video stream () having a second resolution, from a first compressed video stream () having a first resolution. The apparatus comprises means () for extracting transform domain luma data and spatial domain chroma data from the first compressed video stream (), means (-) for applying a transform domain operation to the luma data to form reconstructed transform domain luma data, means () for applying a spatial domain operation to the chroma data to form reconstructed spatial domain chroma data, and means for scaling the reconstructed transform domain luma data and reconstructed spatial domain chroma data to generate the second compressed video stream.
