摘要： A method for dual-standard coding of very low data-rate images and a coder-decoder system for implementing the method, wherein images can be transmitted with low spatial "Quarter of Common Intermediate Format" (QCIF) resolution and with high time resolution according to a first standard, or with high spatial "Common Intermediate Format" (CIF) resolution and low time resolution according to a second standard. In the method and system, the coding of the images includes calculating the mean value of the quantification steps used by a quantifier circuit, comparing the calculated mean value with a first predetermined threshold value and with a second predetermined threshold value higher than the first threshold value, and, chronologically, coding the images in the first standard when the mean value of the quantification steps is lower than the first predetermined threshold value, then coding the images in the first standard as long as the mean value of the quantification steps is lower than the second predetermined threshold value, then coding the images in the second standard as long as the mean value of the quantification steps is higher than the second predetermined threshold value, then coding the images in the first standard when the mean value of the quantification steps is lower than the first predetermined threshold value.

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.
