摘要
针对低比特率通信,对MPEG-4 Simple Visual Profile的编码特性进行剖析,并对影响编码速度最大运动估计与运动补偿进行讨论,提出实现MPEG-4 Simple Visual Profile编码模式,通过对待压缩帧数据的定义提出MB码流的构成,为MPEG-4编码器在移动通信设备上的实现建立一个研究的基础平台。
This article has deeply analyzed encoder characteristics for MPEG-4 Simple Visual Profile to low rate communication and discussed influence of Motion Estimation and compensation the largest coding speed in all parts of MPEG -4 encoder. The coding pattern based on MPEG -4 Simple Visual Profile has been given, preferred constitute of MB coding stream by definition of a compressing video frame, the research platform is built for mobile communication based on MPEG -4 Simple Visual Profile.
