摘要：
The invention relates to a method for encoding a video image sequence into frequency subband coefficients of different spatial resolutions consisting in forming at least two data flows (13) consisting of at least one rendering level (Niv N-2, Niv N-1, Niv N) which comprises frequency subband coefficients whose spatial resolution is equal to the rendering level spatial resolution. Said invention is characterised in that the inventive method also consists in inserting frequency subband coefficients of a spatial resolution which is greater than the rendering level spatial resolution(s) into at least one rendering level.
