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.

High-performance video transcoding method

Disclosed is a method () and an apparatus () for generating a scaled motion vector for a particular output coding unit, the method comprising determining () statistics of motion data from an area-of-interest selecting () from a pre-defined set (-) of re-sampling filters a re-sampling filter dependent upon said determined statistics for the particular output coding unit, and applying the selected re-sampling filter to motion vectors from said area-of-interest to generate the scaled motion vector.
