Abstract
A computer-implemented method and apparatus for processing signals. According to a preferred embodiment, a rate controller determines an initial quantization level for quantizing a block of coefficient signals representative of an image, wherein coefficient signals quantized with a given quantization level are associated with a quantization error. At least one new quantization level is generated in accordance with the initial quantization level. The quantization error associated with the initial quantization level and the at least one new quantization level is determined. A quantization level is selected from the initial quantization level and the at least one new quantization level in accordance with this determination.
