VIDEO CODING METHOD USING AT LEAST EVALUATED VISUAL QUALITY AND RELATED VIDEO CODING APPARATUS

摘要

A video coding method includes at least the following steps: utilizing a visual quality evaluation module for evaluating visual quality based on data involved in a coding loop; and referring to at least the evaluated visual quality for deciding a target bit allocation of a rate- controlled unit in video coding. Besides, a video coding apparatus has a visual quality evaluation module, a rate controller and a coding circuit. The visual quality evaluation module evaluates visual quality based on data involved in a coding loop. The rate controller refers to at least the evaluated visual quality for deciding a target bit allocation of a rate-controlled unit. The coding circuit has the coding loop included therein, and encodes the rate-controlled unit according to the target bit allocation.
