Abstract
A reusable quantization value Qref included in history information or parameter information is obtained in step S. In step S, it is judged whether or not the quantization value Qref obtained in step Sis smaller than a predetermined minimum quantization value Qmin. If it has been judged that the quantization value Qref is smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S, where the quantization value Q is set at Qmin, and then the process is completed. If it has been judged that the quantization value Qref is not smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S, where the quantization value Qref is reused and is set as the quantization value Q, and then the process is completed. The present invention can be applied to an SDTI CP-ASI converter or a long GOP encoder.
