...的MPEG-4编码都比基于帧的MPEG-4编码效率高，所以ObjectVideo同时进行两种编码，基于对象(object-based)的和基于帧(frame-based)的，最终取视频质量较好的编码结果作为输出，输出码流符合MPEG-4 main profile规范。分割后分别编码的视频对象在解码端合成。
There are two ways in which this is primarily done: frame-based offsets that apply to all coefficients or just some portion of them, and macroblock-level offsets.
主要有两种做法：适用于所有的系数或只是其中一些部分的基于帧的偏移量，和宏块级的偏移。
