ＭＰＥＧ－４是一个正在制定的编码标准，除了具有 ＭＰＥＧ－１和 ＭＰＥＧ－２标准的基于“帧”的功能以外，ＭＰＥＧ－４视频编码算法还支持多媒体环境中对视频景物内的“物体”进行存取与操纵。文中描述了第四版ＭＰＥＧ－４视频验证模型的结构及其提供的主要编码工具和算法。
MPEG-4 is an encoding standard under development. In addition to frame-based functions with MPEG-1 and MPEG-2 standards, the MPEG-4 video encoding algorithm also supports “objects” in video scenes in a multimedia environment Access and manipulation. This paper describes the structure of the fourth edition of MPEG-4 video authentication model and its main coding tools and algorithms.
