Variable bitrate video coding method and corresponding video coder

摘要

variable bit rate coding method according to the invention comprising a first and a second analysis route predicted route comprises an integrated handle . Analysis path enables the picture coding of a sequence according to a predetermined quantization step size ( and quality ) predicted route is to match the step size to the desired target bit rate . After several iterations , the final step is to enable fine adjustment of the step size for the target bit -rate ; application : the MPEG2 encoder for the storage medium having a limited capacity
