[Mp4-tech] Video --H.264

[stefano battista]

ciao Luca--
the meaning of P skip is similar to what is done in H263 and MPEG4 video:
a MB without transform coefficients and without motion vectors...
the tricky thing is that you need to apply the correct MV predictor and classify the MB "P skip" if and only if it has **differential MV null** rather than **absolute MV null**...
hope this helps,

  Hi all
        Can anyone explain me the meaning of the P_Skip mode used by H.264 ?
  I don't understand what it is used to make the prediction of this block.
  Thanks in advantage for any kind of help
