Abstract (en)
[origin: WO2013160597A1] The subject of the present invention pertains to a device (100) for decompressing a digital video stream comprising at least one compressed image (I'), said device comprising: - a means of progressive decompression (M4) configured so as to decode said at least one compressed image (I'), and - a means of inverse phase-shifting (M5) configured so as to horizontally and/or vertically phase shift the chrominance plane, for each field (tf, bf) of said at least one decompressed image (I'), according to a determined horizontal (dhi) and/or vertical (dvi) inverse phase shift value, said horizontal (dhi) and/or vertical (dvi) inverse phase shift value being dependent on the horizontal (dh) and/or vertical (dv) phase shift values.
