<span style>Hi</span><div style>You are quiet expert in intra prediction process and so you may know how i can solve my problem. </div><div style>I want to detect the 4x4 intra prediction modes by just parsing a h.264 video file. it look like a partial decoder just for extracting intra prediction modes.

<div style>In chapter 7 says <font color="#000099">rem_intra4x4_pred_mode</font> is an unsigned integer in 3 bit and (<font color="#000099">u(3)</font> and <font color="#000099">ae(v)</font> ). but with 3 bit in <font color="#000099">u(3)</font> how can we represent 9 mode? and how can i interpret <font color="#000099">ae(v)</font>?</div>
