METHOD AND APPARATUS FOR PERFORMING ADAPTIVE ENCODING RATE CONTROL OF A VIDEO INFORMATION STREAM INCLUDING 3:2 PULL-DOWN VIDEO INFORMATION

摘要

A method (200) and apparatus (100) for adapting and enhancing the behavior of an MPEG-like encoder to the presence and/or absence of 3:2 pull-down processed video information within a video information stream to be encoded. Specifically, a rate controller (140) within an MPEG-like encoder (100), in response to a detection (142; 235) of 3:2 pull-down processing of material to be encoded (IN), such as mixed mode video material, dynamically allocates (225-255) a group of pictures (GOP) bit budget (R).
