摘要

A lossless encoding method can include the steps of: determining a lossless encoding mode of quantization coefficients to be one of an infinite range lossless encoding mode and a finite range lossless encoding mode; encoding the quantization coefficients in the infinite range lossless encoding mode in response to a result of the determining of the lossless encoding mode; and encoding the quantization coefficients in the finite range lossless encoding mode in response to the determining of the lossless encoding mode.
