Hi,
I am going through the Rate control in h.264. Rate control can be done
at three levels - GOP level, frame level, macroblock level. We should
either with GOP level and frame level or GOP level and macroblock
level rate control.
I have gone through the do***ent provided by JM reference. Here, in
case of frame level and macroblock level rate control - linear model
to calculate the MAD of current frame from previous frame is used and
quadratic model to calculate QP is used.
I am not able to understand this linear model and quadratic model ??
Can anyone help me
to know the underlying concept?
