Abstract
The invention relates to a method of video processing applied to N encoded video input signals, for decoding and reducing by a factor N the format of said encoded video input signals, and for generating a set of decoded video signals in the pixel domain, each encoded video input signal comprising DCT blocs. The method according to the invention is characterized in that it comprises a first and second inverse DCT step, each inverse DCT step being applied simultaneously on a plurality of DCT blocs of reduced size extracted from said N encoded video input signals. Thus are generated N output blocs of reduced size defining one of said decoded video signal of reduced format by a factor N. This invention can advantageously be used for the composition of mosaic video signals from a set of encoded signals.
