摘要： The method comprises a coding of a source block according to a coding mode wherein the selection of the coding mode is carried out, for a source block, according to coding error estimations and source block coding cost estimations for the different coding modes tested, the coding error being estimated, for a coding mode, according to the sum of the absolute values of coefficients obtained after a mathematical transformation in the frequency domain of the residue block related to this coding mode and as a function of the sum of absolute values of quantized coefficients corresponding to this coding mode. An application is the decision of the coding mode for data using the MPEG 2 or MPEG4-AVC standard.

摘要： This process to convert frames into frames with a larger format is characterized in that it carries out a motion estimation (5) of the current frame relatively to a previous extended view, it compensates in motion (6) the previous extended view relatively to the current frame, it updates the previous extended view (7) by taking into account data from the current frame to give an updated extended view becoming the previous extended view for the motion estimation of the next current frame, it completes the current frame (8) with data from the up-dated extended view to provide the frame with a larger format. The applications concern the 4/3 to 16/9 TV format conversion for 16/9 TV sets.

摘要： The invention relates to a method for generating for at least one macroblock of a high resolution image at least one motion predictor from motion data associated to macroblock(s) of a low resolution image. The method comprises the following steps: —defining a virtual structure made up of non overlapping macroblocks, called virtual base layer macroblocks; —identifying for the high resolution macroblock corresponding virtual base layer macroblocks in the virtual image on the basis of the location of the high resolution macroblock within the high resolution image and on the basis of the ratios of low resolution and high resolution images dimensions; —deriving, for each identified virtual base layer macroblocks, motion data from motion data associated to at least one macroblock of a corresponding low resolution macroblocks pair on the basis of the field/frame mode of the corresponding low resolution macroblocks pair and on the basis of the field/frame mode of the high resolution macroblock; —resampling motion data associated to the corresponding virtual base layer macroblocks so as to generate the at least one motion predictor.
