    摘要: The method wherein the field or frame mode is selected according to the following steps: determination of a motion vector associated with a co-located macroblock of a macroblock to be coded and finding in the next reference picture, a predefined macroblock to be coded, for the selection, in field or frame mode, scaling of the motion vector according to the temporal distances between the reference pictures corresponding to this motion vector and between the current picture, field or frame, according to a predefined mode and a reference picture chosen from among the reference pictures corresponding to this motion vector, determination of the temporal macroblock in the chosen reference picture, designated by the motion vector scale attributed to the macroblock to be coded, and its field or frame coding mode, selection of field or frame coding mode of the temporal macroblock for the coding of the current macroblock. The applications relate to the compression of data using for example the MPEG4 part 10 standard.

    摘要: Said method comprises using a processing means for quantizing a transform of a residual of an intra-prediction of the image block using a quantization parameter value and encoding the quantized transform, further using a processing means for determining that an already used quantization parameter value and corresponding coding cost are available in a storage means, the already used a quantization parameter value being already used for quantizing of a further image block close resembling the image block or having a same complexity as the image block and using the already used quantization parameter value, the corresponding coding cost and a target bit rate for determining the quantization parameter value. Thus, the quantization parameter value can be determined such that flickering artifacts are avoided.
