[Mp4-tech] H.264 motion vectors

[Luca Del Vecchio]

Hi all,
I'm implementing an H.264 decoder and it seems that JM9.2 encoder may
generate motion vectors referring to pixels outside the picture
boundaries.
>From my understanding of the code, in these cases the borderline pixels
are repeated as necessary to get the complete reference. Is it correct?
I've tried to verify what observed before looking into the standard, (my
copy is an old one: JVT-G050r1.doc), but I was not able to find
something about that. Could you help me?
Best regards.
